Brief Summary:

PURPOSE: this study aimed to investigate the effect of opposite knee position on hamstring flexibility BACKGROUND Hamstrings tightness is one of the most common findings in patients with LBP. It is thought that, due to the attachments of hamstrings to the ischial tuberosity, hamstrings tightness generates posterior pelvic tilt and decreases lumbar lordosis, which can result in LBP.

HYPOTHESES There will be significant difference in the hamstring flexibility with changing position of opposite knee (flexed or extended) in patients with mechanical low back pain.

RESEARCH QUESTION: Will changing position of opposite knee (flexed or extended) affect the hamstring flexibility in patients with mechanical low back pain?


Condition or disease Intervention/treatment
Flexibility Other: Hamstring Flexibility

Detailed Description:
  • The subject will be instructed to maintain 90° hip flexion in the supine position.
  • Then asked to actively extend the knee joint.
  • The degree of achieving active knee extension will be measured using a universal goniometer.
  • The average of three active knee extension measurements will be recorded used as the hamstring muscle length for the data analysis (Dong-Kyu Lee, et al., 2018).
  • This test will be done for the same limb with opposite leg extended and with opposite flexed.

  • Other: Hamstring Flexibility

    The active knee extension test has been proposed as the gold standard for assessment of hamstring flexibility, as it utilizes readily available equipment and offers a quick, reliable, and low-cost alternative for measurement of hamstring flexibility (Connor et al; 2015).

    • The subject will be instructed to maintain 90° hip flexion in the supine position.
    • Then asked to actively extend the knee joint.
    • The degree of achieving active knee extension will be measured using a universal goniometer.
    • The average of three active knee extension measurements will be used as the hamstring muscle length for the data analysis (Dong-Kyu Lee, et al; 2018).

      • the procedures will be done with opposite-leg flexed, then repeated with opposite-leg extended.


Primary Outcome Measures :
  1. Knee extension ROM [ Time Frame: 30 minutes ]
    measuring knee extension ROM from 90 degrees hip flexion with opposite-leg flexed and extended
