Strength and functional improvement using pneumatic brace with extension assist for end-stage knee osteoarthritis
Cherian, J.J., Bhave, A., Kapadia, B.H., Starr, R., McElroy, M.J., and Mont, M.A. (2015) J. Arthroplasty. 30(5): 747-53. doi: 10.1016/j.arth.2014.11.036.
Increased quadriceps strength
Brace users experienced a 54% gain to their quadriceps muscle strength.
Increased Hamstring strength
Brace users experienced a 24% gain to their hamstring muscle strength.
Functional test improvements
Brace users made significant improvements in three functional tests.
A novel pneumatic unloader brace (OA Rehabilitator) with an active swing-assist and neuromuscular retaining properties was evaluated across multiple patient outcomes in a prospective, randomized trial. After a minimum of 3 months, patients were assessed for changes in muscle strength, objective function, subjective function, pain, quality of life, and conversion to total knee arthroplasty. When compared with a matched cohort, the patients, all of whom had end-stage knee osteoarthritis (OA), showed significant improvements in muscle strength, several functional tests, and patient reported outcomes.
