ABPMR PM&R common mistakes
ABPMR PM&R · Understand the traps and how to avoid them.
Reads a prolonged distal latency or slowed conduction velocity as demyelination without first confirming limb temperature and without applying age-, height-, and sex-adjusted normative values.
Candidates memorize a single set of cutoff numbers from training and treat them as universal, forgetting that cold limbs slow conduction and that normal values shift with height and age.
What to do instead
Warm the limb to at least 32 degrees C, use the laboratory's own normative tables, and adjust for height and age before labeling any finding demyelinating.
On needle EMG, calls fibrillation potentials and positive sharp waves 'acute denervation' within days of a nerve injury, or labels a painful weak limb as radiculopathy without showing a myotomal pattern across multiple muscles.
The Wallerian degeneration timeline is known loosely, and pain-nearby-muscle reasoning substitutes for systematic myotomal mapping.
What to do instead
Recall that spontaneous activity appears roughly 2 to 3 weeks after nerve injury; require a distribution concordant with myotomes and with NCS or imaging before committing to a radicular diagnosis.
Anchors on a benign musculoskeletal label such as lateral epicondylitis, hamstring strain, or IT band syndrome in a patient with night pain, fever, weight loss, or pain far out of proportion to exam, and never screens for fracture, infection, or tumor.
Outpatient sports medicine pattern-matching rewards the common diagnosis, and red flags are not systematically elicited under time pressure.
What to do instead
Run an explicit red-flag screen (night pain, systemic symptoms, trauma, age over 50 with new pain, neuro deficits) before finalizing any soft-tissue diagnosis.
In a hemiplegic shoulder, treats pain as rotator cuff tendinitis without examining for glenohumeral subluxation, pectoralis or subscapularis spasticity, or complex regional pain syndrome.
The candidate carries an outpatient musculoskeletal frame into a neurologic patient and examines only the tendon.
What to do instead
Palpate and measure subluxation, test passive external rotation and scapular mobility, and screen for CRPS features before attributing pain to the rotator cuff.
Equates any increased tone with spasticity, missing rigidity or cogwheeling, or labels velocity-independent lead-pipe tone as spasticity and thus mislocalizes the lesion.
Tone is assessed only at one speed, so velocity dependence, the defining feature, is never tested.
What to do instead
Test passive range at slow and then fast speeds; velocity-dependent catch with clasp-knife release indicates spasticity, while velocity-independent resistance suggests rigidity or another cause.
Mistakes aphasia, hemispatial neglect, or cognitive impairment for noncompliance, depression, or 'poor motivation,' and sets rehabilitation goals without formally screening language and attention.
Behavioral labels are applied before standardized bedside screening, and aphasia can mask preserved cognition.
What to do instead
Perform a formal language and neglect screen early, use non-verbal or augmented communication, and build goals on demonstrated capacity rather than observed cooperation.
In a patient with SCI at T6 or above who reports headache with flushing, sweating, and elevated blood pressure, attributes the episode to anxiety or migraine and does not check bladder and bowel.
Autonomic dysreflexia is treated as a medical trivia item rather than a bedside emergency drill.
What to do instead
Treat as autonomic dysreflexia: sit the patient upright, check and relieve bladder and bowel distension, remove noxious stimuli, and use antihypertensives only if the trigger cannot be corrected.
Reassures parents that loss of a previously attained milestone is normal variation, or attributes it to prematurity well past age 2, instead of pursuing regression as a red flag.
Milestone checklists are memorized as ages to achieve, not as skills that must be retained, and prematurity is over-used as an explanation.
What to do instead
Treat any loss of attained skills as pathologic until proven otherwise; document the specific lost milestones and refer for urgent neurologic and metabolic evaluation.
Writes a fixed botulinum toxin dose and muscle set for every 'spastic diplegia' or 'spastic hemiplegia' without naming a functional goal, using guidance, or respecting redosing intervals.
Protocol habits from training replace goal-directed planning, and antibody risk plus unwanted weakness from spread are underweighted.
What to do instead
Set a measurable functional goal first, select muscles by exam with ultrasound or EMG guidance, use the lowest effective dose, and keep intervals of at least 12 weeks.
Orders a wheelchair by diagnosis alone, such as a power chair for cerebral palsy, without a seating and mobility assessment covering posture, pressure distribution, and transfer ability, leading to pressure injury or shoulder overuse.
The prescription is treated as an equipment order rather than a functional assessment, and pressure mapping is skipped.
What to do instead
Perform a mat assessment with posture, range, and pressure mapping, match the device to mobility goals and environment, and document the justification for the specific configuration.
