TREATMENT FOR LOWER-LIMB MUSCLES BY SQUEEZE-HOLD TECHNIQUE IS VERY VALID FOR KNEE OA: ONE-YEAR FOLLOW-UP STUDY OF THREE CASES

The International Society for Technology in Arthroplasty (ISTA), 27th Annual Congress. PART 3.



Abstract

Introduction

Knee osteoarthritis (OA) is a major contributor to disability in seniors and affecting millions of people around the world. Its main problem and the biggest factor in the disability of patients is pain. Pain renders patient inactive and develops lower extremity muscle wasting and worsens patient status adversely. However no radical solution existed until now. Recently I discovered a very valid manipulative technique (Squeeze-hold) for OA knee. This study presents the one-year follow-up data (three cases) by this treatment.

Methods

Subjects

The subjects were three severe knee OA patients who had their data collected for 12 months after having a treatment. Treatment (squeeze-hold): The lower limb muscles (all muscles attached to the knee joint) were squeezed and held by hand. Each squeeze was performed in linear sequence all the way through the lower limbs. The squeezes were held for 20 seconds. This treatment was performed on a weekly basis. Evaluation: The conditions of the OA were evaluated using a Kellgren-Lawrence Grading Scale. Visual analogue scale as indicator of pain and Japanese Knee Osteoarthritis Measure as indicator of the activity restriction were recorded every month for a year.

Results

In all three cases, OA knee pain and ADL were gradually improved by sustained once-a-week treatment. The daily activities were gradually increased. After a year, the pain passed approximately away. In case 1 and 2, a limitation in ROM did not show a marked improvement and joint contracture remained.

Discussion

Squeeze-hold therapy that is approach to lower-limb muscles relieved OA knee pain. It is suggested by the fact that lower-limb muscles is responsible for the pain. And the physical activity of knee OA patient increases with decreasing pain effected by Squeeze-hold therapy. This increase in physical activity provides increase in joint movement and it lead to improve articular metabolism. Cyclical loading increases chondrocyte activity. Additionally, It inhibits the release of matrix metalloproteinase, pro-inflammatory mediators and shear stress-induced nitric oxide that induces chondrocyte apoptosis. And further, this increased physical activity improves muscle-strengthening of the lower extremity. It is plausible that these effects may continuously lead to decreased pain and improved ADL. A primary pain in knee OA can be attributed to inflammation of knee joint capsule or within knee joint capsule. And the pain leads to muscular hypertonicity thereby a bigger secondary pain develops in the muscles. Decreased physical activity due to the pain worsens pathological condition to induce greater pain. By this means, there might be formed pain-deterioration chain. Squeeze-hold therapy reduces the myogenic pain and cut the pain-deterioration chain. However, ROM could not improve though the pain and ADL activity imploved. This treatment ought to be performed before the formation of articular contracture.

The results indicate Squeeze-hold treatment for lower-limb muscles might improves OA knee pain and limited ADL. However, this study had only three cases. Further research efforts are needed to identify the adaptation to diverse clinical symptoms knee OA.
