Introduction: Low back pain is a syndrome with multifactorial etiology that affects 6.8% of the world population during life time. Therefore, the aims of this study was to examine the effect of rehabilitation with medicine ball on muscle activity in low back pain.
Patients during Walking
Methods: The present study was a clinical trial.  The statistical population of the present study included patients with low back pain that randomly divided into two intervention (age: 25.4±2.5 years, weight: 79.04±3.06 kg, height: 176.03±7.04 cm) and control (age: 25.8±2.09 years, weight: 79.00±3.01 kg, height: 176.06±7.01cm) group. The intervention group performed resistance training with medicine ball and the control group participated in pre-test and post-test only, without performing any training. were recorded muscle activities of the gastrocnemius lateral (GAS-L), biceps femoris (BF),semitendinosus (ST), vastus medialis (VM), external abdominal (ABD-L), rectus abdominal (ABD-R) and erector spinae (ES).
Results:  The results of the present study showed an increase in the frequency spectrum of the rector femoris muscle during the heel contact and push off in experimental group in post-test compared to the pre-test, and indict a statistically significant difference, Also, the frequency spectrum of the right abdominal muscle in the experimental group has decreased in the post-test compared to the pre-test during the pushing phase, and indict a statistically significant difference .
Conclusion: Rehabilitation with a medicine ball leads to increase the activity the quadriceps muscles in low back pain patients, and it seems to be important factor in decrees the shock absorption during walking.
