Tokyo, May 10 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000061504) titled 'Comparative Effects of Low-Level and High-Intensity Laser Therapy on Neuromuscular Function and Balance in Healthy Older Adults: A Randomized Controlled Trial' on May 9.

Study Type: Interventional

Study Design: Basic Design - Parallel Randomization - Randomized Blinding - Single blind -participants are blinded Control - Active

Primary Sponsor: Institute - Integrative Exercise Physiology Laboratory, Department of Physical Education, Jeonbuk National University,

Condition: Condition - Healthy older adults with age-related lower-limb neuromuscular and balance function decline Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - To compare the effects of high-energy laser therapy and low-energy laser therapy on pain, knee-related symptoms, peri-knee muscle stiffness, neuromuscular co-activation during squatting and standing, and static and dynamic balance performance in healthy older adults. Basic objectives2 - Efficacy

Intervention: Interventions/Control_1 - High energy laser therapy group: Participants received high energy laser therapy with the LMD LT 30 laser therapy device. The treatment was delivered at a wavelength of 1064 nm with an output power of 5 W. Each treatment session lasted 30 minutes, consisting of 10 minutes of pulsed irradiation followed by 20 minutes of continuous irradiation. Treatment was provided three times per week for 12 weeks. The laser was applied with a slow scanning technique over an area of approximately 8 square centimeters around the knee, including the anteromedial, anterolateral, medial, and lateral knee regions, as well as the joint line. The total energy delivered in each session was 9000 J, with an energy density of 1125 J per square centimeter. Interventions/Control_2 - Low energy laser therapy group: Participants received low energy laser therapy using the same scanning method and treatment area as the high energy laser therapy group. The treatment was delivered at a wavelength of 830 nm with a peak power output of 400 mW. Each treatment session lasted 30 minutes, consisting of 10 minutes of pulsed irradiation followed by 20 minutes of continuous irradiation. Treatment was provided three times per week for 12 weeks. The laser was applied over the same area of approximately 8 square centimeters around the knee. The total energy delivered in each session was 720 J, with an energy density of 90 J per square centimeter.
