EFFECT OF MOTOR CONTROL EXCERCISES ON ELECTROMYOGRAPHIC RESPONSES IN BACK MUSCLES IN PATIENTS WITH LOW BACK PAIN. A PILOT STUDY
Authors : E. S. Prathyush

Background & Purpose: Low back ache is one of common disorder experienced by all the individuals in their lives. Muscle strength and flexibility essential for maintaining the spine in neutral. The main muscle of the back is the erector spine which is commonly affected. To improve the function of erector spine muscles there are so many protocols available. Now a days the importance of motor control exercises
was increased in improving muscle activity and Electro-myographic application to the back muscle is limited so, the purpose of the study is to record the activity of the erector spine muscle after motor control exercise.

Objectives: The objective of this study was to know the electro-myographic changes of the erector spine after motor control exercise in low back pain patients and comparing the test results with pain levels and strength gained.

Methodology: 20 subjects are included in the study, 10 in each group. Experimental group received motor control exercises and interferential therapy, conventional group received flexion and extension exercises and interferential therapy for a duration of 6 weeks. Exercises were given for 30 minutes and IFT for 15 minutes per day. Muscle activity is recorded before and after the intervention. The EMG amplitude and fiber density were used as outcome measures. The outcome was measure before the treatment and after 6 weeks.

Result: After 6 weeks the EMG amplitudes of erector spine muscles in experimental and conventional group were compared. P value is 0.0002, considered extremely significant with t = 4.660. The comparison between post treatment values of fiber density of erector spine muscles in experimental and conventional group considered extremely significant with P value is < 0.0001,
t = 5.680.

Conclusion: Motor control exercises are showing positive changes in EMG activity of erector spine muscles than conventional
exercises while treating patients with chronic low back ache .this can conclude that motor control exercises are more specific in treating
patients with chronic low back ache.
Key words: Motor control exercises, low back ache, electromyography.
