Effect of Neuromuscular Electrical Stimulation Integrated with Closed Kinetic Chain Exercises on Strength of Quadriceps Muscle
Keywords:Neuromuscular electrical stimulation, Closed kinetic exercise, Maximum isometric voluntary contraction, Quadriceps
Background & Objective: Electrical stimulation has been well studied in strengthening of weak muscles.
Incorporating high-intensity NMES into rehabilitation program for muscle strengthening is an effective
option available for restoring quadriceps strength. The clinical use of CKC has significantly increased during
the past two decades as these exercises concentrates on a co-contraction of the quadriceps, hamstrings, hip
flexors, soleus, and gastrocnemius muscles and are labeled as being “sport specific movements. Literature
available till date has been largely inconsistent whether combining NMES with either of strength training
will produce better results. Therefore, in present study we propose to integrate NMES and CKC exercises
protocols in improving strength of Quadriceps Femoris.
Method: Thirty Healthy subjects were recruited, group A(n=10) combination technique, group B(n=10)
NMES, group C(n=10), CKC group: were given training for 3 days/ week for 4 weeks.
Result and Conclusion: maximum improvement resulted in Group C, followed by Group A and minimum
improvement in Group B.
