Active Release Technique Verses Proprioceptive Neuromuscular Facilitation on Hamstring Flexibility in Patients Having Specific Low Back Pain

Comparative Effects of Active Release Technique Verses Proprioceptive Neuromuscular Facilitation on Hamstring Flexibility in Patients Having Specific Low Back Pain

The goal of this clinical trial is to learn whether Active Release Technique (ART) or Proprioceptive Neuromuscular Facilitation (PNF) is more effective in improving hamstring flexibility in adults with specific low back pain. It will also look at how these treatments affect pain and movement.

The main questions it aims to answer are:

Does ART or PNF improve hamstring flexibility more in people with specific low back pain?

Do participants report reduced pain and better movement after receiving either treatment?

Researchers will compare the effects of ART and PNF to see which method works better for improving flexibility and reducing pain.

Participants will:

Receive either ART or PNF therapy for 2 weeks

Attend regular physiotherapy sessions during the treatment period

Be assessed before and after treatment for hamstring flexibility and pain levels

This randomized controlled trial was designed to compare the effectiveness of Active Release Technique (ART) and Proprioceptive Neuromuscular Facilitation (PNF) in improving hamstring flexibility among individuals with specific low back pain. Reduced hamstring flexibility is a common contributing factor in low back dysfunction, and identifying the most effective manual therapy technique can guide more targeted physical therapy interventions.

Participants were randomly assigned to receive either ART or PNF over a 2-week intervention period. Both groups received treatment administered by trained physiotherapists using standardized protocols. ART focused on applying specific manual pressure to soft tissues while moving the muscle through its range of motion, while PNF employed contract-relax stretching techniques to promote muscle lengthening and neuromuscular facilitation.

Participants were evaluated at baseline and after the completion of the intervention for changes in hamstring flexibility, with secondary observations on pain reduction and functional improvement. The study adhered to ethical standards, and all participants provided informed consent prior to participation.

The trial contributes to evidence-based physiotherapy by offering comparative insight into two widely used manual techniques in musculoskeletal rehabilitation.
