OBJECTIVE: To determine whether the combination of stochastic resonance (SR)
electrical stimulation and a neoprene knee sleeve could improve center of
pressure (COP) measures of postural sway during single-leg stance in those with
knee osteoarthritis (OA). DESIGN: Counterbalanced, repeated-measures intervention
study of osteoarthritic adults during 6 different testing conditions: a control
condition-control 1 (1); a counterbalance sequence of 4 treatment conditions-no
stimulation with sleeve (2),
75% stimulation with sleeve (3), 100% stimulation
with sleeve (4), and 150% stimulation with sleeve (5);
and a second control
condition-control 2 (6). SETTING: University sports medicine research laboratory.
PARTICIPANTS: Subjects (N=52) with radiographically determined,
minimal-to-moderate medial knee OA. INTERVENTIONS: Neoprene knee sleeve and SR
electrical stimulation. MAIN OUTCOME MEASURES:
COP displacement in the
medial-lateral and anterior-posterior directions was collected to resolve the
mean velocity, SD, range, and total path length. RESULTS: No significant
differences were found in the study measures between the testing conditions.
Additionally, no significant differences were found between the 3 stimulation
conditions or between the sleeve-alone and stimulation conditions for any of the
study measures. CONCLUSIONS: There were no significant improvements in balance
with the use of a neoprene knee sleeve. Additionally, there was no added benefit
of the SR stimulation as applied in the current configuration in this population.
