Laser Therapy on Hamstring Muscle Among Young Adults

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.

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Asymptomatic young adults
  • Both gender
  • Tightness of hamstring muscles

  • Any other musculoskeletal disorder
  • Any disc pathology
  • Any nerve root irritation
  • Any surgical history or trauma

Treatment and study plan

Active High-intensity laser therapy

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-

  • 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

Device

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

Primary outcomes

  1. Active Knee Extension Test

    Time frame: 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

    Time frame: Changes will be measured at baseline, end of two week post intervention

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