CO Treatment Planning & Protocols 3

Question 1

A patient with L3-L4 spinal stenosis has neurogenic claudication limiting walking to 50 feet. Which orthotic approach is supported by evidence?

Accepted Answer

Lumbar flexion orthosis to open the spinal canal

Answer

Lumbar flexion orthoses open the posterior elements of the spinal canal, reducing stenotic compression and alleviating neurogenic claudication symptoms.

Question 2

Which outcome measure is MOST appropriate for assessing functional improvement in a patient fitted with a lower limb orthosis for stroke?

Accepted Answer

10-Meter Walk Test (10MWT)

Answer

The 10-Meter Walk Test is a validated, functional measure of walking speed that directly captures the ambulation benefits of lower limb orthotics in stroke patients.

Question 3

A patient with idiopathic scoliosis (Cobb angle 28°, Risser 2) presents for orthotic management. Which brace and wearing protocol is standard of care?

Accepted Answer

Boston TLSO or equivalent, worn 16-23 hours/day

Answer

Evidence-based guidelines (SRS/POSNA) recommend a rigid TLSO worn 16-23 hours per day to halt curve progression during the adolescent growth phase.

Question 4

When writing a treatment plan for a unilateral transtibial amputee, what is the primary biomechanical purpose of a prosthetic sock fit check at each visit?

Accepted Answer

Evaluate residual limb volume changes affecting socket fit

Answer

Residual limb volume fluctuates due to activity, edema, and tissue remodeling; sock ply adjustments ensure proper socket fit and prevent skin breakdown.

Question 5

A pediatric patient with myelomeningocele at the L2 level has no active hip flexion below that level. Which orthotic system best enables therapeutic ambulation?

Accepted Answer

Hip-knee-ankle-foot orthoses (HKAFOs) with pelvic band

Answer

L2 level spina bifida results in absent hip extension and knee control; HKAFOs with a pelvic band provide the necessary proximal stability for therapeutic ambulation.
