Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

High-intensity laser therapy

77 participants will receive active high-intensity laser therapy interventions on hamstring muscle to improve the flexibility of muscle

Group Type EXPERIMENTAL

Active High-intensity laser therapy

Intervention Type DEVICE

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-

1. Wavelength- 980 nm
2. Intensity/Power density- 3W/cm2
3. Emission mode- Continuous Emission
4. Energy (Joules)- 490 J
5. Irradiation time- 70 Sec on each point
6. Peak power- 15 Watt
7. Irradiation points- 09

Sham High-intensity laser therapy

77 participants will receive sham high-intensity laser therapy on hamstring muscle

Group Type SHAM_COMPARATOR

Sham High-intensity laser therapy

Intervention Type DEVICE

Sham High-intensity laser therapy will be used in the contact method, without the laser beam irradiation over the hamstring muscle.
