Interventions

  • Spray and stretch technique on Hamstring Muscle — OTHER
    The participant will be positioned in a comfortable supine lying position on a treatment table in a quiet and suitable clinical environment. Before starting the intervention, the procedure will be explained to the participant in simple language, and verbal confirmation of comfort will be obtained. The affected lower limb will be exposed appropriately while ensuring privacy, modesty, and warmth through proper draping with towels or sheets. The participant will be instructed to relax the lower limb during the procedure. The hip will be maintained in a neutral position, and the knee will be kept straight or slightly flexed according to the participant's comfort before the stretching component begins. The therapist will first inspect the posterior thigh region to ensure that the skin is intact and suitable for vapocoolant application. The presence of any open wound, skin infection, rash, hypersens
  • Strain and counter strain technique on hamstring muscle — OTHER
    identify the tender point Palpate the hamstring while the patient is prone or side lying locate the most tender point in belly of the muscle or near the ischial tuberosity Establish a pain scale and Ask the patient to rate the tenderness from 0 to 10 (10 being the most painful).Position of ease will be achieved by Flexing the patient's knee to about 70 to 90 degrees .Slightly abduct and externally rotate the leg to shorten the hamstring muscle (the position may vary depending on the muscle .The goal is to reduce tenderness by at least 70% .Hold the position and Maintain this position of comfort for 90 seconds Encourage the patient to relax during this time .Return the leg passively to a neutral position to avoid reactivating the trigger point .Palpate the tender point again and ask for a new pain rating.

Study Details

Non-specific low back pain refers to pain in the lower back region that cannot be attributed to a specific identifiable pathology such as infection, tumor, osteoporosis, lumbar disc herniation, spinal stenosis or fracture. It is the most common type of low back pain, accounting for about 85-90% of cases. Non specific low back pain is posteriorly occurring that is located between lower rib margin and gluteal fold. It is exacerbated by sustained back postures, back movements or back muscle imbalances. The aim of study is to find out which technique whether Spray and stretch technique or strain Counter strain works better in reducing pain ,improving movement ,and decreasing disability caused by tight hamstring muscles in people with non specific low Back Pain.

Arms

  • Experimental: Spray and stretch technique on Hamstrings muscle
    The spray and stretch technique is a physical therapy method used to inactivate myofascial trigger points, reduce muscle spasms, and increase range of motion. It works by applying a vapocoolant spray to numb the skin, which interrupts the pain signal, allowing the therapist to safely stretch the muscle
  • Active Comparator: Strain and counter strain technique on Hamstring muscle
    Strain-Counterstrain (SCS) is a gentle, hands-on physical therapy technique used to relieve low back pain by "resetting" the nervous system. By placing the body in specific, pain-free positions, it relaxes tight muscles, reduces muscle guarding, and improves mobility

Primary Outcome Measure

Numeric pain rate scale (NPRS) [ Time Frame: Baseline and after 4 weeks of intervention ]
