Brief summary

To investigate the effect of adding open versus closed chain segmental control exercises to conventional treatment program on pain intensity, lumbar ROM, and CSA of multifidus muscle.

Detailed description

* To investigate the effect of adding open versus closed chain segmental control exercises to conventional treatment program on pain intensity. * To investigate the effect of adding open versus closed chain segmental control exercises to conventional treatment program on lumber ROM. * To investigate the effect of adding open versus closed chain segmental control exercises to conventional treatment program on CSA of multifidus muscle. * To investigate the effect of adding open versus closed chain segmental control exercises to conventional treatment program on lumber function.

Interventions

OTHERConventional treatment

Application of ultrasound and transcutaneous electrical nerve stimulation "TENS" for mechanical low back pain.

OTHEROpen chain segmental control
