Comparison of Task Oriented Therapy and Modified Constraint Induced Movement Therapy along with Functional Electrical Stimulation to Improve Hand Function In Sub Acute Stroke survivors: a Randomized Control Trial
Keywords:Stroke, Functional Electrical Stimulation, hand function, dexterity, rehabilitation.
Background: The study aims to investigate the effectiveness of 6 weeks of two-channel functional
electrical stimulation assisted hand training along with Task Oriented Training and Modified Constraint
Induced Movement Therapy on the restoration of hand function in subacute stroke patients. Trial design: A
Multi–group pre test–post test design randomized controlled study was conducted with 30 individuals with
upper-limb motor impairment after stroke. Method: Participants was randomly assigned into three groups
FES-TOT, FES- mCIMT and FES-Ctrl groups. All participants were treated for 90 minutes a day, 5 times
a week for 6 weeks. Hand function was assessed by Action Research Arm Test score (primary outcome),
Grip strength, Pinch strength and Stroke Impact Scale (secondary outcome). Result: There was statistical
significance (p<.05) between the groups for ARA and Grip strength outcome measures. It was found that
subjects in both experimental groups (but FES-TOT > FES-mCIMT,) showed more improvement in ARA
score and grip strength (lateral pinch and three jaw chuck pinch) as compared to control group (FES-CTRL).
Conclusion: It is concluded that training with FES along with TOT is more effective in improving Hand
function and grip strength as compared to mCIMT and conventional hand rehabilitation. However studies
with large sample size are required for generalizability of the finding based on statistical analysis.
