Is there a dose response for valgus unloader brace usage on knee pain, function, and muscle strength?

Objective: To examine whether there was a dose response for valgus unloader brace wear on knee pain, function, and muscle strength in participants with medial compartment knee osteoarthritis.

Design: In this single-group study, participants with medial compartment knee osteoarthritis were followed for approximately 6 months.

Setting: Recruitment was conducted in the general community, and testing was performed at a university laboratory.

Effect of a high intensity quadriceps fatigue protocol on knee joint mechanics and muscle activation during gait in young adults.

The purpose of this study was to determine the effect of impaired quadriceps function on knee joint biomechanics and neuromuscular function during gait. Surface electromyograms, three-dimensional motion and ground reaction forces were collected during gait before and after 20 healthy adults completed a high intensity quadriceps fatigue protocol. Pattern recognition techniques were utilized to examine changes in amplitude and temporal characteristics of all gait variables.
