Study Details

Study Description

Brief Summary

A total of 154 healthy young individuals will be recruited by purposive sampling method to participate in a randomized, single-blinded, sham-controlled study. Recruited participants will be randomly dividing into two groups, the Active high-intensity laser therapy (a-HILT) group, and the Sham high-intensity laser therapy (s-HILT) group. The treatment duration will be 10 minutes per session on both lower limbs for each day for 3 days/week for 2 weeks. Hamstring muscle length will be assessed at baseline, end of the 2-week post-intervention period.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: High-intensity laser therapy 77 participants will receive active high-intensity laser therapy interventions on hamstring muscle to improve the flexibility of muscle	Device: Active High-intensity laser therapy; High-intensity laser therapy will be used in the contact method, with the laser beam irradiated over the hamstring muscle. Dosage and parameters for the laser will be calculated. Parameters- Wavelength- 980 nm Intensity/Power density- 3W/cm2 Emission mode- Continuous Emission Energy (Joules)- 490 J Irradiation time- 70 Sec on each point Peak power- 15 Watt Irradiation points- 09
Sham Comparator: Sham High-intensity laser therapy 77 participants will receive sham high-intensity laser therapy on hamstring muscle	Device: Sham High-intensity laser therapy; Sham High-intensity laser therapy will be used in the contact method, without the laser beam irradiation over the hamstring muscle.

Outcome Measures

Primary Outcome Measures

1. Active Knee Extension Test [Changes will be measured at baseline, end of two week post intervention]

   Active knee extension test (AKET) is most reliable method to assess the hamstring tightness.

2. Sit and toe touch test [Changes will be measured at baseline, end of two week post intervention]

   Sit and toe touch test is used to assess the hamstring flexibility
