Immediate Effects of High-intensity Laser Therapy on Knee Joint Position Sense and Knee Muscle Strength in Patients with Knee Osteoarthritis
- Conditions
- Knee Osteoarthritis
- Interventions
- Device: high-intensity laser therapyDevice: Sham-HILT
- Registration Number
- NCT06632119
- Lead Sponsor
- Mahidol University
- Brief Summary
The goal of this clinical trial is to compare whether HILT versus Sham-HILT is effective to reduce pain, improve knee joint position sense, and knee muscle strength.
Participants will undergo a single-session of HILT or Sham-HILT, the measurements of pain, knee joint position sense error, and knee muscle strength will be done at before, immediately after, and 24-hour after the single-session intervention.
- Detailed Description
The investigators would like to investigate whether single session of high-intensity laser therapy (HILT) is promising to see the changes in individuals with knee osteoarthritis (KOA)-related knee pain regarding pain intensity, knee joint position sense, and knee muscle strength.
The objectives of this study is to compare pre and post, and between the two groups (HILT versus Sham-HILT) at after interventions regarding pain, knee joint position sense, and knee muscle strength.
Participants will undergo a single-session of HILT or Sham-HILT by an experienced musculoskeletal physical therapist, the measurements of pain, knee joint position sense error, and knee muscle strength will be done at before, immediately after, and 24-hour after the single-session intervention.

- Primary Outcome Measures
Name Time Method Knee joint position sense Baseline, immediately after, 24-hour after intervention Knee joint position sense, the investigators used the joint position repositioning technique. The participants were measured for joint position reposition technique with a smartphone application "Measure App" (iPhone 12 Pro Max, Apple Inc., USA). The smartphone attached at shank of tibia bone at the malleolar level. The participants sat in the starting position knee flexion 90°. Then the participants with eyes closed were actively guided to the knee flexion 45 degrees and hold for 3 seconds. The data was recorded the difference between performed position and targeted position.
- Secondary Outcome Measures
Name Time Method Knee muscle strength Baseline, immediately after, 24-hour after intervention The muscle strength measured both quadriceps and hamstring muscles by the handheld dynamometer at 90°.
Pain Baseline, immediately after, 24-hour after intervention The participants rated the pain scores using a 10-cm visual analog scale (VAS) ranged from 0 "no pain at all" on the left end to 10 "worst pain imaginable" on the right end.
