CO study plan

CO · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Patient Assessment and Evaluation & Design, Measurement, and Casting/Scanning

  • Build a one-page assessment checklist covering history, vascular status, sensation, skin integrity, and functional/ROM findings for lower- and upper-limb patients

  • List the objective measurements taken at initial evaluation (girth, length, joint ROM, muscle strength, skin condition) and state the clinical reason for each

  • Define the key landmarks and measurement techniques used for transtibial, transfemoral, and upper-limb casting or scanning

  • Complete 30 practice questions on assessment and measurement, logging every miss with the underlying concept

Your checkpoint

Annotated assessment-and-measurement checklist plus a scored 30-question practice set with a written error log

Week 2

Design, Measurement, and Casting/Scanning & Patient Assessment and Evaluation

  • Explain indications, advantages, and limitations of hand casting versus digital scanning for each major amputation level

  • Describe the steps of casting a transtibial residual limb, including patient positioning and pressure application

  • Identify common casting and scanning errors (rotation, inadequate pressure, wrong landmarks) and the resulting fit problems

  • Interpret a residual limb assessment to select an appropriate suspension strategy

Your checkpoint

A written comparison table of casting vs. scanning by amputation level, plus five worked case vignettes linking assessment findings to design choices

Week 3

Formulation of the Treatment Plan & Design, Measurement, and Casting/Scanning

  • Draft a treatment-plan template that translates assessment findings into prescription decisions (componentry, socket design, suspension, alignment)

  • Justify socket and suspension choices for at least four patient profiles with differing activity levels and limb characteristics

  • Sequence design, measurement, and fabrication steps for a transtibial device from evaluation to delivery

  • Complete 30 practice questions on treatment planning and design, reviewing each rationale

Your checkpoint

A completed treatment-plan template applied to four patient profiles, with a scored 30-question practice set

Week 4

Fabrication, Modification, and Assembly & Design, Measurement, and Casting/Scanning

  • Outline the fabrication workflow for a transtibial and a transfemoral prosthesis, naming each modification step and its purpose

  • Explain bench alignment principles and how they are verified before dynamic fitting

  • Identify common fabrication defects and the fitting problems each produces

  • Describe modification techniques for socket reliefs, buildups, and trim lines

Your checkpoint

A fabrication and bench-alignment flowchart for two device types, plus a defect-to-symptom troubleshooting list

Week 5

Fabrication, Modification, and Assembly & Fitting, Delivery, and Patient Education

  • Describe the assembly and component-selection checks performed before a device leaves the lab

  • List the sequence of fitting and delivery steps, including static and dynamic alignment checks

  • Draft a patient-education outline covering donning/doffing, skin checks, wear schedule, and warning signs

  • Match common delivery complaints (pressure, pistoning, rotation) to corrective actions

Your checkpoint

A delivery-day checklist and a one-page patient-education handout for a transtibial user

Week 6

Fitting, Delivery, and Patient Education & Follow-Up, Maintenance, and Outcome Evaluation

  • Explain how to teach a patient to inspect and care for the residual limb and device at home

  • Identify follow-up intervals and the outcome measures used to track function, comfort, and satisfaction

  • Interpret outcome data to decide whether to adjust, modify, or remake a device

  • Complete 25 practice questions on fitting, education, and follow-up, reviewing rationales

Your checkpoint

A follow-up and outcome-tracking plan with a scored 25-question practice set

Week 7

Follow-Up, Maintenance, and Outcome Evaluation & Practice Management, Ethics, and Professional Standards

  • Summarize the ethical and professional standards relevant to patient care and documentation

  • Describe scope-of-practice boundaries and appropriate referral pathways

  • Explain documentation and record-keeping requirements across the care episode

  • Complete 20 practice questions on follow-up and practice management, reviewing each rationale

Your checkpoint

A one-page ethics and documentation quick-reference sheet plus a scored 20-question practice set

Week 8

Patient Assessment and Evaluation & Formulation of the Treatment Plan & Design, Measurement, and Casting/Scanning & Fabrication, Modification, and Assembly & Fitting, Delivery, and Patient Education & Follow-Up, Maintenance, and Outcome Evaluation & Practice Management, Ethics, and Professional Standards

  • Complete two full-length timed mock exams under test conditions

  • Categorize every missed item by domain and root cause (knowledge gap vs. misread)

  • Re-review the highest-miss domains using the error logs from weeks 1-7

  • Write a final one-page summary of the ten concepts most likely to trip you up

Your checkpoint

Two scored mock exams with a domain-by-domain error analysis and a one-page final review sheet

Milestones

Week 2: Score at least 75% on a 30-question assessment-and-design set and explain casting vs. scanning tradeoffs without notes

Week 4: Reproduce the fabrication and bench-alignment workflow for two device types from memory and correctly map five defects to their symptoms

Week 6: Score at least 80% on the combined fitting, education, and follow-up question sets and deliver a complete patient-education handout

Week 8: Score at least 80% on both full-length mock exams, with no domain below 70% on the error analysis
