Question 1Orthotic patient assessment

During an initial orthotic assessment, which finding is documented as a measure of lower-limb alignment rather than a functional measure?

  1. Berg balance score
  2. Timed up-and-go score
  3. Tibial torsion angle Correct answer.
  4. Six-minute walk distance

Explanation

Structural alignment measures describe the geometry of the limb, such as torsion, angulation, and leg-length difference, and are recorded separately from performance-based tests. Walking and balance tests quantify function rather than bony alignment.

Question 2Orthotic patient assessment

A patient reports numbness over the plantar aspect of the first web space. Which neurologic level is most consistent with this finding?

  1. L5 nerve root Correct answer.
  2. S2 nerve root
  3. L4 nerve root
  4. S1 nerve root

Explanation

Sensation on the dorsum and plantar surface of the first web space is supplied by the L5 dermatome. S1 covers the lateral foot and sole, while S2 covers the posterior thigh and popliteal region.

Question 3Orthotic patient assessment

Which measurement best quantifies a fixed ankle equinus contracture during assessment?

  1. Weight-bearing lunge distance alone
  2. Passive dorsiflexion with the knee flexed and extended Correct answer.
  3. Active dorsiflexion in sitting
  4. Resistive plantarflexion strength grade

Explanation

Fixed equinus is assessed by passive dorsiflexion with the knee both flexed and extended, which distinguishes gastrocnemius from soleus involvement and identifies the end-feel. Active and resisted tests assess function and strength rather than contracture.

Question 4Orthotic patient assessment

A patient's leg-length discrepancy is suspected to arise from the tibia. Which measurement technique best isolates tibial length?

  1. Umbilicus to medial malleolus
  2. Anterior superior iliac spine to medial malleolus
  3. Medial joint line of the knee to medial malleolus Correct answer.
  4. Fibular head to lateral malleolus

Explanation

Measuring from the medial knee joint line to the medial malleolus isolates the tibial segment. The other techniques include the femur or pelvis and therefore measure total limb length.

Question 5Orthotic patient assessment

During gait observation, a patient shows excessive knee flexion throughout stance. Which assessment finding would most directly explain this pattern?

  1. Plantarflexor spasticity
  2. Hip flexion contracture
  3. Genu recurvatum
  4. Knee flexion contracture Correct answer.

Explanation

A fixed knee flexion contracture prevents full extension in stance, producing a crouched pattern. Plantarflexor spasticity typically produces equinus, and hip flexion contracture produces increased lumbar lordosis or trunk flexion.

Question 6Orthotic patient assessment

Which finding on vascular assessment would prompt deferral of a rigid total-contact orthosis until medical review?

  1. Absent pedal pulses with dependent rubor Correct answer.
  2. Warm, dry skin with intact hair growth
  3. Brisk capillary refill of two seconds
  4. Palpable posterior tibial pulse

Explanation

Absent pedal pulses with dependent rubor suggest compromised arterial perfusion, which raises the risk of skin breakdown under a rigid device. Normal pulses, brisk capillary refill, and intact skin and hair indicate adequate perfusion.

Question 7Orthotic patient assessment

In a patient with diabetes and peripheral neuropathy, which assessment tool is most appropriate for identifying loss of protective sensation?

  1. Ankle brachial index
  2. Two-point discrimination on the dorsum of the foot
  3. 10-g monofilament testing at plantar sites Correct answer.
  4. Vibration tuning fork at the knee

Explanation

The 10-g monofilament is the standard screen for loss of protective sensation at plantar weight-bearing sites. Vibration and two-point discrimination assess other sensory modalities, and the ankle brachial index evaluates perfusion.

Question 8Orthotic patient assessment

A patient with a C6 spinal cord injury is being assessed for a hand orthosis. Which function is most likely preserved?

  1. Intrinsic hand muscle control
  2. Thumb opposition
  3. Wrist extension Correct answer.
  4. Full finger flexion

Explanation

Wrist extension is innervated by the radial nerve, which is largely spared at the C6 level, allowing tenodesis grasp. Finger flexors, intrinsics, and thumb opposition depend on lower segments and are typically impaired.

Question 9Orthotic patient assessment

Which component of the initial assessment most directly informs the choice between a prefabricated and a custom-fabricated device?

  1. Shoe size
  2. Patient's preferred color
  3. Degree of deformity correctability and limb volume stability Correct answer.
  4. Insurance coverage limits

Explanation

Custom fabrication is indicated when the deformity is not correctable by prefabricated designs or when limb volume changes require close conformity. Color and shoe size are secondary, and coverage is a logistical rather than clinical determinant.

Question 10Orthotic patient assessment

A patient presents with a rigid, non-reducible plantarflexed first ray. Which orthotic design element is most appropriate to accommodate this finding?

  1. A high lateral flange
  2. A medial heel wedge
  3. A first-ray cutout or recess in the shell Correct answer.
  4. A deep heel cup

Explanation

A rigid plantarflexed first ray cannot be corrected and must be accommodated with a recess or cutout to prevent focal pressure. Wedges, flanges, and heel cups do not relieve pressure over an inflexible first ray.

Question 11Orthotic patient assessment

Which documentation element is essential when recording a measured joint range of motion?

  1. The manufacturer of the goniometer
  2. The patient's occupation
  3. The clinician's years of experience
  4. The presence or absence of pain at end range Correct answer.

Explanation

Documenting pain at end range clarifies whether limitation is due to pain or to tissue restriction, which affects device design. Occupation, clinician experience, and goniometer brand are not part of the range-of-motion record.

Question 12Orthotic patient assessment

A patient with rheumatoid arthritis has severe forefoot deformity with multiple subluxations. Which assessment finding most strongly supports a custom-molded foot orthosis over an off-the-shelf insert?

  1. Rigid, non-correctable forefoot deformity with skin at risk Correct answer.
  2. Mild callus under the second metatarsal
  3. Bilateral pes planus with flexible deformity
  4. Occasional heel pain after prolonged standing

Explanation

Rigid deformity with threatened skin requires total-contact custom molding to distribute pressure. Flexible or mild findings can often be managed with prefabricated devices.

Question 13Orthotic patient assessment

Which test is used to assess hip flexor length during an orthotic evaluation?

  1. Ober test
  2. Thomas test Correct answer.
  3. Trendelenburg test
  4. Ely test

Explanation

The Thomas test assesses hip flexor length by observing whether the thigh remains elevated when the contralateral hip is flexed. The Ober test assesses iliotibial band tightness, the Ely test assesses rectus femoris tightness, and the Trendelenburg test assesses hip abductor function.

Question 14Orthotic patient assessment

A patient demonstrates a positive Trendelenburg sign on the right during left single-leg stance. Which finding does this indicate?

  1. Right hip adductor contracture
  2. Left ankle instability
  3. Left hip abductor weakness Correct answer.
  4. Right hip abductor weakness

Explanation

The Trendelenburg sign is named for the side of the stance limb; the pelvis drops on the swing side when the stance-side hip abductors are weak. A positive sign during left stance therefore indicates left hip abductor weakness.

Question 15Orthotic patient assessment

Which of the following best describes the purpose of a static evaluation in orthotic assessment?

  1. Observing the patient's gait across multiple trials
  2. Assessing endurance during sustained activity
  3. Recording the patient's functional history
  4. Measuring alignment and posture in a stationary position Correct answer.

Explanation

Static evaluation records alignment, posture, and measurements while the patient is stationary. Dynamic evaluation observes movement, and history-taking captures functional and medical background.

Question 16Orthotic patient assessment

A patient reports burning pain and tingling in the distribution of the sural nerve after wearing a new ankle-foot orthosis. Which assessment action is most appropriate?

  1. Inspect the device for focal pressure over the lateral ankle and adjust Correct answer.
  2. Add a heel lift to the contralateral shoe
  3. Increase the trim line height over the lateral malleolus
  4. Reduce wearing time without inspecting the device

Explanation

Nerve irritation symptoms after fitting indicate focal pressure and require inspection and modification of the device at the symptomatic site. Raising the trim line or altering the opposite limb does not address the source of pressure.

Question 17Orthotic patient assessment

Which measurement is most useful for determining the appropriate length of a knee-ankle-foot orthosis shell?

  1. Femoral condyle to medial malleolus distance Correct answer.
  2. Greater trochanter to lateral malleolus
  3. Tibial tubercle to dorsum of the foot
  4. Popliteal crease to heel

Explanation

Knee-ankle-foot orthosis length is determined by measuring from the femoral condyles to the medial malleolus to establish the shell's proximal and distal extent. The other measurements include segments outside the device's span.

Question 18Orthotic patient assessment

A patient with a fixed pelvic obliquity is being assessed for a spinal orthosis. Which finding is most important to document before fabrication?

  1. Shoulder range of motion
  2. Grip strength
  3. Trunk balance in sitting and standing Correct answer.
  4. Shoe size difference

Explanation

Trunk balance in both sitting and standing determines the orthosis's ability to support the spine and guides design. Shoe size, shoulder motion, and grip strength are not primary determinants of spinal orthosis design.

Question 19Orthotic patient assessment

Which of the following findings suggests a flexible rather than rigid flatfoot deformity?

  1. Arch present in non-weight-bearing and absent in weight-bearing Correct answer.
  2. Fixed forefoot varus with no correction
  3. Arch absent in both non-weight-bearing and weight-bearing
  4. Rigid hindfoot valgus that does not change with loading

Explanation

A flexible deformity corrects when unloaded, so the arch appears in non-weight-bearing and disappears in weight-bearing. Absence of the arch in both positions indicates a rigid deformity.

Question 20Orthotic patient assessment

A patient's foot shows forefoot varus in the non-weight-bearing position. Which orthotic posting is typically required to compensate?

  1. Lateral heel wedge
  2. Medial forefoot posting Correct answer.
  3. Anterior tibial posting
  4. Forefoot valgus posting

Explanation

Forefoot varus means the medial side of the forefoot is elevated relative to the rearfoot, so medial posting brings the forefoot to the floor. Lateral posting would worsen the deformity.

Question 21Orthotic patient assessment

Which assessment finding would contraindicate a rigid total-contact orthosis in a patient with a neuropathic foot?

  1. Intact protective sensation
  2. Active plantar ulceration over the first metatarsal head Correct answer.
  3. Mild pes cavus
  4. Bilateral hallux valgus

Explanation

Active ulceration requires offloading and wound care before a rigid device is applied, since rigid materials can worsen pressure over an open wound. Intact sensation, mild cavus, and hallux valgus are not contraindications.

Question 22Orthotic patient assessment

During gait analysis, a patient shows a foot slap immediately after initial contact. Which muscle group is most likely weak?

  1. Knee flexors
  2. Ankle plantarflexors
  3. Ankle dorsiflexors Correct answer.
  4. Hip abductors

Explanation

Foot slap occurs when the dorsiflexors cannot eccentrically control plantarflexion after heel strike. Plantarflexor weakness produces push-off deficits, and hip abductor weakness produces pelvic drop.

Question 23Orthotic patient assessment

Which of the following best describes the role of a patient interview in orthotic assessment?

  1. Establishing goals, history, and functional expectations Correct answer.
  2. Determining the exact material thickness
  3. Assessing skin integrity
  4. Measuring joint range of motion

Explanation

The interview captures the patient's history, goals, and functional expectations, which guide device selection and design. Material thickness, range of motion, and skin integrity are determined by physical examination.

Question 24Orthotic patient assessment

A patient with a transfemoral amputation is being assessed for a prosthesis. Which measurement is most relevant to socket design?

  1. Thoracic spine curvature
  2. Contralateral shoe size
  3. Ischial tuberosity to medial tibial plateau length and residual limb circumference Correct answer.
  4. Wrist circumference

Explanation

Transfemoral socket design depends on residual limb length measured from the ischial tuberosity and on circumferential measurements for fit. Shoe size, wrist circumference, and thoracic curvature do not inform socket design.

Question 25Orthotic patient assessment

Which assessment finding most strongly indicates the need for a foot orthosis with arch support in a patient with plantar fasciitis?

  1. Pain with resisted knee extension
  2. Pain with the first steps in the morning and tenderness at the medial calcaneal tubercle Correct answer.
  3. Pain at the lateral malleolus with palpation
  4. Pain with resisted ankle eversion

Explanation

Morning pain with the first steps and tenderness at the medial calcaneal tubercle are classic for plantar fasciitis, which responds to arch support that reduces strain on the fascia. The other findings suggest peroneal or knee pathology.

Question 26Orthotic patient assessment

During an initial orthotic assessment, which measurement best establishes a baseline for detecting later swelling in a limb that will be fitted with a custom device?

  1. Circumferential girth measured at a marked, reproducible landmark Correct answer.
  2. Joint range of motion measured with a goniometer
  3. Manual muscle test grade of the surrounding musculature
  4. Two-point discrimination at the distal limb

Explanation

Serial girth measurement at a consistent, marked landmark is the standard way to track volume change over time, because the same reference point allows meaningful comparison between visits. Range of motion, strength, and sensation describe other domains and do not quantify limb volume.

Question 27Orthotic patient assessment

A patient is unable to actively dorsiflex the ankle but retains full passive dorsiflexion range. Which conclusion does this finding support?

  1. The limitation is due to pain-limited guarding of the calf
  2. The limitation is due to bony block at the anterior joint margin
  3. The limitation is due to capsular contracture of the ankle
  4. The limitation is due to lost motor function rather than joint restriction Correct answer.

Explanation

When passive range exceeds active range, the joint and soft tissue envelope can still be moved through the arc, so the deficit lies in the motor system producing the motion. Contracture, bony block, or guarding would restrict passive range as well.

Question 28Orthotic patient assessment

Which piece of information gathered during the patient interview most directly shapes the wearing schedule prescribed with a new orthosis?

  1. The patient's preferred color of strap closure
  2. The patient's insurance coverage for replacement devices
  3. The patient's daily routine and tolerance for wearing time Correct answer.
  4. The patient's handedness for donning the device

Explanation

Wearing schedules are built around how long and how often a device can be tolerated within the patient's daily activities, so routine and tolerance are the driving factors. Coverage, handedness, and cosmetic preferences affect logistics or design details but not the progression of wear time.

Question 29Orthotic patient assessment

A patient walks with a markedly increased cadence and short step length bilaterally, and reports fear of falling. Which gait parameter should be documented to capture this pattern?

  1. Walking speed along with step and stride length Correct answer.
  2. Calcaneal pitch angle in standing
  3. Single-leg stance duration on the unaffected limb only
  4. Pelvic rotation measured in supine

Explanation

Short steps with high cadence are captured by measuring speed together with step and stride length, which together characterize the cautious gait pattern. The other measures describe static alignment or isolated components and do not describe the overall temporal-distance pattern.

Question 30Orthotic patient assessment

A patient with a long-standing below-knee amputation presents with a firm, non-tender, movable nodule at the distal tibial remnant. What is the most appropriate next step in orthotic/prosthetic assessment?

  1. Proceed with casting and note the finding only in the final report
  2. Delay casting until the patient reports pain at the site
  3. Increase distal socket relief and proceed without referral
  4. Document the finding and refer for medical evaluation before fabricating a socket Correct answer.

Explanation

Any new or unusual residual-limb finding should be documented and cleared medically before a definitive socket is fabricated, because the tissue condition affects both safety and fit. Proceeding without evaluation risks skin breakdown and masks a condition that may need treatment.

Question 31Orthotic patient assessment

During assessment of a child with a flexible flatfoot, the arch reappears when the child stands on tiptoe. Which interpretation is most accurate?

  1. The deformity is supple and potentially responsive to a flexible orthosis Correct answer.
  2. The deformity is rigid and requires surgical referral
  3. The finding confirms tibialis anterior weakness
  4. The finding indicates a forefoot varus deformity

Explanation

Re-formation of the arch with toe standing demonstrates that the subtalar joint can still invert and the deformity is flexible, which supports a flexible accommodative device. A rigid deformity would not correct with this maneuver, and the test does not isolate a single muscle.

Question 32Orthotic patient assessment

A patient with a C7-level tetraplegia is being evaluated for a wrist-hand orthosis. Which muscle action is most likely available to assist tenodesis grasp?

  1. Elbow extension via the triceps brachii
  2. Finger flexion via the flexor digitorum profundus
  3. Wrist extension via the extensor carpi radialis Correct answer.
  4. Thumb opposition via the opponens pollicis

Explanation

At the C7 level, wrist extensors are innervated and can drive a tenodesis effect, allowing passive finger flexion when the wrist extends. The long finger flexors, thenar muscles, and triceps are innervated at levels below or at the margin of C7 and are not reliably available.

Question 33Orthotic patient assessment

A patient reports that a leather ankle-foot orthosis becomes uncomfortably tight after several hours of standing. Which assessment finding best explains this?

  1. Reduced vibratory sensation in the toes
  2. Weakness of the ankle dorsiflexors
  3. Fixed equinus contracture of the ankle
  4. Dependent edema that increases limb volume during the day Correct answer.

Explanation

Dependent edema causes limb volume to rise with prolonged standing, so a device fitted in the morning can become tight later in the day. Contracture, sensory loss, and weakness affect alignment or safety but do not explain time-dependent tightness.

Question 34Orthotic patient assessment

When assessing a patient for a shoe insert, which finding is most important to record because it determines whether the insert must accommodate or correct the rearfoot?

  1. The width of the forefoot at the metatarsal heads
  2. The height of the medial longitudinal arch in non-weight bearing
  3. The resting calcaneal stance position relative to the lower leg Correct answer.
  4. The length of the second metatarsal

Explanation

Resting calcaneal stance position describes how the rearfoot sits relative to the tibia under load and therefore guides whether the insert accommodates or attempts to correct the rearfoot. Metatarsal length, forefoot width, and non-weight-bearing arch height inform sizing and shape but not rearfoot strategy.

Question 35Formulation of an orthotic treatment plan

Which component of an orthotic treatment plan defines the specific biomechanical goals the device must achieve?

  1. The patient education materials
  2. The billing and coding documentation
  3. The prescription and design rationale Correct answer.
  4. The problem list and functional limitations

Explanation

The prescription and design rationale translate the assessment findings into specific device requirements, such as controlling motion, redistributing pressure, or providing stability. This section states the biomechanical objectives the orthosis is intended to accomplish.

Question 36Formulation of an orthotic treatment plan

A patient with a healed tibial fracture has 5 degrees of ankle dorsiflexion and needs to clear the foot during swing. Which orthotic design goal is most appropriate?

  1. Apply a varus correction strap
  2. Limit plantarflexion to 0 degrees
  3. Provide a rigid ankle block to prevent motion
  4. Add a dorsiflexion assist to aid foot clearance Correct answer.

Explanation

Limited dorsiflexion impairs swing-phase foot clearance, so a dorsiflexion assist helps lift the foot. A rigid block or plantarflexion limit would not address clearance and could worsen gait.

Question 37Formulation of an orthotic treatment plan

When formulating an orthotic plan for a patient with peripheral neuropathy and a history of plantar ulcers, which outcome measure is most relevant to monitor?

  1. Peak plantar pressure at the ulcer site Correct answer.
  2. Knee flexion strength
  3. Hip abductor strength
  4. Ankle dorsiflexion range of motion

Explanation

In neuropathic ulcer management, reducing peak plantar pressure is a primary orthotic goal because elevated pressure contributes to tissue breakdown. Range of motion and proximal strength are secondary considerations in this context.

Question 38Formulation of an orthotic treatment plan

A patient with multiple sclerosis has fluctuating tone and fatigue that varies throughout the day. Which orthotic plan feature is most important?

  1. A custom-molded foot orthosis only
  2. An adjustable or articulated design that can accommodate changes Correct answer.
  3. A fixed, rigid ankle-foot orthosis for maximum stability
  4. A knee-ankle-foot orthosis with locked knee

Explanation

Fluctuating symptoms require a device that can be adjusted or that accommodates varying tone and fatigue. A fixed rigid design may be too restrictive on better days and insufficient on worse days.

Question 39Formulation of an orthotic treatment plan

Which factor is most critical when deciding whether to use an off-the-shelf versus a custom-fabricated orthosis?

  1. The manufacturer's warranty
  2. The clinician's familiarity with the product
  3. The patient's insurance coverage
  4. The complexity and uniqueness of the patient's anatomy and needs Correct answer.

Explanation

Custom fabrication is indicated when the patient's anatomy or functional requirements cannot be adequately addressed by standard sizes or shapes. Insurance, familiarity, and warranty are secondary considerations.

Question 40Formulation of an orthotic treatment plan

In an orthotic treatment plan, what is the primary purpose of specifying wearing schedules and break-in periods?

  1. To satisfy documentation requirements for reimbursement
  2. To ensure the patient gets used to the device gradually and avoids skin breakdown Correct answer.
  3. To reduce the cost of the device
  4. To test the durability of the materials

Explanation

Gradual introduction of an orthosis helps the patient adapt and allows clinicians to monitor for skin irritation or pressure problems. This is a clinical safety measure, not an administrative one.

Question 41Formulation of an orthotic treatment plan

A patient with a C6 spinal cord injury has weak wrist extensors and needs a tenodesis grasp. Which orthotic goal is most appropriate?

  1. Provide powered finger flexion
  2. Stabilize the wrist in slight extension to enhance tenodesis Correct answer.
  3. Immobilize the fingers in extension
  4. Prevent wrist extension to allow passive finger flexion

Explanation

Tenodesis grasp relies on wrist extension causing passive finger flexion. A wrist-hand orthosis that positions the wrist in slight extension can enhance this mechanism without blocking it.

Question 42Formulation of an orthotic treatment plan

When planning an orthosis for a child with cerebral palsy and spastic equinus, which consideration is most important for the design?

  1. The device should be as rigid as possible to block all motion
  2. The device should be made of the lightest possible material
  3. The device should accommodate growth and be adjustable Correct answer.
  4. The device should only be worn at night

Explanation

Children grow rapidly, so orthoses must accommodate growth and be adjustable to maintain fit and function. Rigidity and material weight are secondary to growth accommodation.

Question 43Formulation of an orthotic treatment plan

Which of the following best describes the role of a trial period in an orthotic treatment plan?

  1. To evaluate the device's function, comfort, and fit before final acceptance Correct answer.
  2. To test the patient's insurance coverage
  3. To determine the final cost of the device
  4. To fulfill a legal requirement for custom devices

Explanation

A trial period allows the clinician and patient to assess whether the orthosis meets the treatment goals and to make adjustments. It is a clinical evaluation step, not a financial or legal one.

Question 44Formulation of an orthotic treatment plan

A patient with a recent stroke has foot drop and medial knee instability. Which orthosis would best address both problems?

  1. A knee-ankle-foot orthosis with a drop lock knee joint
  2. A hinged ankle-foot orthosis with a medial knee strap Correct answer.
  3. A custom foot orthosis with medial posting
  4. A posterior leaf spring ankle-foot orthosis

Explanation

A hinged AFO with a medial knee strap can provide dorsiflexion assist for foot drop and apply a valgus moment to stabilize the knee. A posterior leaf spring does not address knee instability.

Question 45Formulation of an orthotic treatment plan

When setting orthotic goals for a patient with rheumatoid arthritis and ulnar deviation of the fingers, which is the primary aim?

  1. Increase grip strength
  2. Improve wrist extension range
  3. Prevent further deformity and support function Correct answer.
  4. Reduce inflammation

Explanation

In rheumatoid arthritis, orthoses are used to support joints, prevent progression of deformity, and maintain function. They do not directly reduce inflammation or increase strength.

Question 46Formulation of an orthotic treatment plan

Which patient factor most strongly suggests the need for a weight-bearing orthosis rather than a non-weight-bearing one?

  1. The patient has a desk job
  2. The patient needs to stand for prolonged periods at work Correct answer.
  3. The patient has limited hand dexterity
  4. The patient has a history of falls

Explanation

Prolonged standing requires an orthosis that can withstand weight-bearing forces and provide stability. A non-weight-bearing device would not be adequate for this demand.

Question 47Formulation of an orthotic treatment plan

In the context of orthotic treatment planning, what does the term 'accommodative' approach mean?

  1. The device restricts all joint motion
  2. The device corrects deformity to neutral alignment
  3. The device accepts the existing deformity and relieves pressure Correct answer.
  4. The device is designed for temporary use only

Explanation

An accommodative orthosis is designed to conform to the patient's existing alignment and redistribute pressure rather than correct the deformity. This is often used when correction is not feasible or not indicated.

Question 48Formulation of an orthotic treatment plan

A patient with a Charcot foot requires an orthosis. Which design principle is most important?

  1. Total contact to distribute pressure and accommodate the deformity Correct answer.
  2. Minimal contact to allow skin inspection
  3. Rigid immobilization to prevent further collapse
  4. Flexible materials to allow motion

Explanation

In Charcot foot, a total-contact orthosis distributes pressure over the entire surface, reducing focal loading and accommodating the deformed shape. Rigid immobilization may be used acutely but total contact is key for accommodation.

Question 49Formulation of an orthotic treatment plan

Which of the following is a key component of patient education in an orthotic treatment plan?

  1. Instructions on how to modify the orthosis at home
  2. The billing codes used for reimbursement
  3. Proper donning and doffing techniques Correct answer.
  4. The manufacturing process of the device

Explanation

Teaching the patient correct donning and doffing is essential for safe and effective use of the orthosis. Patients should not modify the device themselves, and manufacturing or billing details are not relevant to their education.

Question 50Formulation of an orthotic treatment plan

When considering an orthosis for a patient with a BMI over 40, which design modification is most likely needed?

  1. Increased structural reinforcement and wider straps Correct answer.
  2. Thinner materials to reduce weight
  3. Smaller footplate to reduce bulk
  4. Decreased ankle control

Explanation

Higher body weight imposes greater forces on the orthosis, so reinforcement and wider straps are often needed to prevent breakage and improve fit. Thinner materials or smaller components would compromise durability.
