Clinical Trial 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.

Related Conditions & MeSH terms

• Muscle Tightness

Intervention

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 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

Type	Measure	Description	Time frame	Safety issue
Primary	Active Knee Extension Test	Active knee extension test (AKET) is most reliable method to assess the hamstring tightness.	Changes will be measured at baseline, end of two week post intervention
Primary	Sit and toe touch test	Sit and toe touch test is used to assess the hamstring flexibility	Changes will be measured at baseline, end of two week post intervention
