This study investigated the use of whole-body vibration (WBV) as an alternative
strengthening regimen in the rehabilitation of individuals with total knee
arthroplasty (TKA) compared with traditional progressive resistance exercise
(TPRE). Individuals post TKA (WBV n = 8; TPRE n = 8) received physical therapy
with WBV or with TPRE for 4 weeks. Primary dependent variables were knee extensor
strength, quadriceps muscle activation, mobility, pain, and range of motion
(ROM). There was a significant increase in knee extensor strength and
improvements in mobility, as measured by maximal volitional isometric contraction
and the Timed Up and Go Test (TUG), respectively, for both groups (p < 0.01). The
WBV knee extensor strength improved 84.3% while TPRE increased 77.3%. TUG scores
improved 31% in the WBV group and 32% for the TPRE group. There were no
significant differences between groups for strength or muscle activation
(Hotelling's T(2) = 0.42, p = 0.80) or for mobility (F = 0.54; p = 0.66). No
adverse side effects were reported in either group. In individuals with TKA, both
WBV and TPRE showed improved strength and function. Influence of WBV on muscle
activation remains unclear, as muscle activation levels were near normal for both
groups.
