Treatment and study plan

conventional treatment

Other

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

Open chain segmental control

Other

Application of "open chain segmental control exercises" As well as, application of ultrasound and transcutaneous electrical nerve stimulation "TENS" for mechanical low back pain.

Closed chain segmental control

Other

Application of "closed chain segmental control exercises" As well as, application of ultrasound and transcutaneous electrical nerve stimulation "TENS" for mechanical low back pain.

Primary outcomes

  1. Cross sectional area of multifidus muscle

    Time frame: Pre and Post measurement (12 weeks)

    Cross sectional area of multifidus muscle

  2. Pain intensity

    Time frame: Pre and Post measurement (12 weeks)

    Measured by VAS (from 0 to 10; 0 means no pain and 10 means worst pain)

Secondary outcomes

  1. ROM of lumbar spine

    Time frame: Pre and Post measurement (12 weeks)

    Measuring ROM of lumbar spine

  2. Functional ability of lumbar spine

    Time frame: Pre and Post measurement (12 weeks)

    Questionnaire for measuring lumbar activities (lower score means better and higher score means worse)
