OBJECTIVE: To compare sensory-level neuromuscular electrical stimulation (NMES)
and conventional motor-level NMES in patients after total knee arthroplasty.
DESIGN: Prospective randomized single-blind trial.
SETTING: Hospital total
arthroplasty center: inpatients. PARTICIPANTS: Patients with osteoarthritis
(N=66; mean age, 73.5+/-6.3y; 85% women) were randomized to receive either
sensory-level NMES applied to the quadriceps (the sensory-level NMES group),
motor-level NMES (the motor-level NMES group), or no stimulation (the control
group) in addition to a standard rehabilitation program. INTERVENTIONS: Each type
of NMES was applied in 45-minute sessions, 5d/wk, for 2 weeks. MAIN OUTCOME
MEASURES: Data for the quadriceps maximum voluntary isometric contraction, the
leg skeletal muscle mass determined using multiple-frequency bioelectrical
impedance analysis, the timed Up and Go test, the 2-minute walk test, the visual
analog scale, and the range of motion of the knee were measured preoperatively
and at 2 and 4 weeks after total knee arthroplasty. RESULTS: The motor-level NMES
(P=.001) and sensory-level NMES (P=.028) groups achieved better maximum voluntary
isometric contraction results than did the control group. The motor-level NMES
(P=.003) and sensory-level NMES (P=.046) groups achieved better 2-minute walk
test results than did the control group. Some patients in the motor-level NMES
group dropped out of the experiment because of discomfort. CONCLUSIONS:
Motor-level NMES significantly improved muscle strength and functional
performance more than did the standard program alone. Motor-level NMES was
uncomfortable for some patients. Sensory-level NMES was comfortable and improved
muscle strength and functional performance more than did the standard program
alone.
