To find the optimal strap tensile force at brace application. External compression by knee braces may impair neuro-muscular function in the leg. Pressures are recorded by the microcapillary infusion technique. The force output is recorded on a Kin-Com ergometer.
Intramuscular oxygenation is recorded with near infrared spectroscopy.
Nerve conduction velocity is recorded with a neurograph. Functional knee braces impair muscle function by decreasing local perfusion pressure and local muscle blood flow during exercise. This is caused by the increased muscle relaxation pressure due to external compression of the brace, and results in premature muscle fatique.
