Effects of High-Intensity Laser Therapy Combined With Exercise in Patients With Knee Osteoarthritis (HILT-KOA)
Effects of High-intensity Laser Therapy on Muscle Strength in People With Knee Osteoarthritis
The goal of this clinical trial was to determine whether high-intensity laser therapy (HILT) combined with exercise improves pain, physical function, and muscle strength in people with knee osteoarthritis.
The main questions the study aimed to answer were:
- Did HILT combined with exercise lower pain more than sham laser combined with exercise?
- Did HILT combined with exercise improve physical function more than sham laser combined with exercise?
- Did HILT combined with exercise improve knee extensor muscle strength more than sham laser combined with exercise?
Researchers compared HILT plus exercise with sham laser plus exercise to determine whether HILT provided additional benefits beyond those achieved with exercise alone.
Participants:
- Received either HILT or sham laser treatment for four weeks.
- Participated in a standardized exercise program.
- Completed assessments of pain, physical function, and muscle strength before and after treatment.

상세 설명
Knee osteoarthritis is a common musculoskeletal condition associated with pain, reduced physical function, and muscle weakness. Exercise therapy is widely recommended as a first-line treatment; however, the additional benefits of high-intensity laser therapy (HILT) remain uncertain. Previous studies have reported improvements in pain and function following HILT, but results have been inconsistent, and its effects on muscle strength have not been fully established.
The purpose of this randomized, participant-blinded, sham-controlled clinical trial was to evaluate the effects of HILT combined with exercise on pain, physical function, and knee extensor muscle strength in people with knee osteoarthritis.
Participants with clinically diagnosed knee osteoarthritis were randomly assigned to one of two groups. The experimental group received HILT combined with a standardized exercise program, while the control group received sham laser treatment combined with the same exercise program. The intervention lasted four weeks and included ten treatment sessions.
Pain intensity, physical function, and knee extensor muscle strength were assessed before and after the intervention using validated clinical outcome measures. The primary objective was to determine whether HILT provides additional benefits beyond those achieved with exercise alone.
The findings of this study may help clarify the role of HILT as an adjunct treatment in rehabilitation programs for people with knee osteoarthritis and contribute to the development of evidence-based clinical recommendations.

실험적: High Intensity Laser Therapy + Exercise
Participants received high-intensity laser therapy (HILT) combined with a standardized exercise program.
HILT was delivered using an MLS laser device (MPHI D, ASA Laser, Italy) over four periarticular knee application points during 10 treatment sessions over four weeks.
The exercise program included strengthening, flexibility, and balance exercises and was identical to that provided to the sham comparator group.

High-intensity laser therapy (HILT) was delivered using an MLS laser device (MPHI D, ASA Laser, Italy), which combines synchronized 808 nm and 905 nm wavelengths.
Treatment was applied to four periarticular knee regions, including the medial and lateral patellar borders, the suprapatellar region, and the medial tibiofemoral joint line.
Participants received 10 treatment sessions over four weeks.
HILT was administered in combination with a standardized exercise program.
다른 이름들:
The exercise program was performed during each treatment session and included strengthening, flexibility, and balance exercises targeting the lower extremities.
Exercises included stationary cycling, hamstring and gastrocnemius stretching, straight-leg raises, knee extensions, heel raises, step-ups, and single-leg balance activities.
The program was standardized for both study groups and was delivered over 10 sessions during a four-week period.

가짜 비교기: Sham Laser + Exercise
Participants received sham laser treatment combined with the same standardized exercise program used in the experimental group.
Sham treatment was delivered using the same laser device and treatment schedule as the active intervention but with subtherapeutic parameters designed to maintain participant blinding.
The intervention consisted of 10 treatment sessions over four weeks.
The exercise program included strengthening, flexibility, and balance exercises.
