To determine whether Bilateral Transcutaneous Electrical Nerve Stimulation (Bi-TENS) +TOT was superior to Unilateral Transcutaneous Electrical Nerve Stimulation (Uni-TENS +TOT, placebo-TENS+TOT and control group in improving the upper limb motor function in people with stroke.
Design : A single-blind randomized, controlled trial
Setting : A local university laboratory
Participants (or Animals, Specimens, Cadavers) :
One hundred and twenty subjects with chronic stroke (76 males, Mean age=61.52±6.73 years, time since stroke=6.04±3.12 years)
Interventions : Subjects received 20 treatment sessions (3 sessions per week for 7 weeks). Two pairs of electrodes were applied over the median nerve and radial nerves of the upper limbs. In the Bi-TENS+TOT group, TENS were applied on bilateral upper limbs. In Uni-TENS+TOT group, TENS was only applied on the affected upper limb, while placebo-TENS was applied on the unaffected side. In the placebo group, the disconnected TENS was applied on bilateral upper limbs. Subjects in these three intervention groups (Bi-TENS, Uni-TENS and placebo-TENS) received TOT during TENS. In the control group, subjects did not receive any active treatment.
Main Outcome Measure(s) :
Fugl-Meyer Assessment of Upper Extremity (FMA-UE) was assessed pre-, mid- and post-intervention.
Bi-TENS+TOT showed a significant greater improvement in FMA-UE (Uni-TENS+TOT: difference in slope=2.03, p=0.007; Placebo TENS+TOT: difference in slope=2.54, p=0.001; Control: difference in slope=3.00; p<0.001) than the other three groups in post-intervention assessment.
Twenty sessions of Bi-TENS+TOT was superior to Uni-TENS+TOT, placebo TENS+TOT and control group in improving FMA-UE in people with stroke.
