A patient 6 weeks post total knee arthroplasty is having difficulty achieving full knee extension. Which intervention should be prioritized?
Answer: Terminal knee extension exercises and prone knee extension stretching
Achieving full knee extension after TKA is critical to prevent flexion contracture; terminal knee extension exercises and prolonged low-load stretching in prone are prioritized.
Which soft tissue mobilization technique involves applying pressure perpendicular to the muscle fiber direction to break up adhesions?
Answer: Cross-friction massage
Cross-friction massage (Cyriax technique) applies transverse pressure perpendicular to tissue fibers to break adhesions and promote proper collagen remodeling.
A patient with patellofemoral pain syndrome shows weakness in which muscle group that most commonly contributes to the condition?
Answer: Hip abductors and external rotators
Weakness in hip abductors and external rotators leads to dynamic valgus collapse and increased lateral patellar stress, contributing to PFPS.
When using neuromuscular electrical stimulation (NMES) for quadriceps strengthening post-ACL reconstruction, which parameter produces the strongest muscle contraction?
Answer: High frequency (50–80 Hz), long pulse width
High frequency (50–80 Hz) with a longer pulse width (200–400 µs) recruits more motor units and produces the strongest tetanic muscle contraction for NMES.
Which orthopedic special test is used to assess for a SLAP lesion of the shoulder?
Answer: Active compression (O'Brien's) test
O'Brien's active compression test is specifically designed to detect SLAP lesions and AC joint pathology through resisted internal and external rotation in flexion.
A patient with a Colles' fracture is 6 weeks post-cast removal. What is the PRIMARY therapeutic goal at this stage?
Answer: Restoring wrist and forearm range of motion
Immediately after cast removal for Colles' fracture, restoring wrist and forearm ROM is the primary goal before progressive strengthening can begin.
Which type of muscle contraction generates the greatest force output?
Answer: Eccentric contraction
Eccentric contractions produce the greatest force because passive elastic elements (titin) contribute alongside active cross-bridge cycling, resulting in supramaximal force.
