High Intensity Laser Therapy (HL) vs Exercise in Thumb Osteoarthritis
High Intensity Laser Therapy (HL) vs Exercise in Thumb Osteoarthritis
Osteoarthritis (OA) is a degenerative joint disease that can affect the hands and is particularly debilitating when it involves the trapeziometacarpal joint (rhizarthrosis). It causes pain, deformity, limited movement and strength, joint instability, resulting in significant limitations in daily activities.Many conservative treatments, such as medications, therapeutic exercises, physical therapy, and orthoses, are effective for managing hand OA. For patients who do not respond to conservative treatments, surgical intervention will be necessary.
Among physical therapies, in recent years particular interest has been focused on the laser (Light Amplification through the Stimulated Emission of Radiation), which exploits the biological effects induced by electromagnetic emission, consisting of increased mitochondrial oxidation, which facilitates the formation of adenosine triphosphate (ATP), increased cellular metabolism, and blood circulation, with rapid absorption of edema and removal of exudates. These actions induce significant anti-inflammatory, proliferative, and analgesic effects on various orthopedic conditions. So far, low-energy lasers have been used in rehabilitative treatments. Currently, there is growing interest in using high-energy lasers, which have a greater ability to penetrate deeply into the tissues and to biostimulate the affected area.The first studies investigating the effects of high-energy laser in this pathology provide interesting results. Medina-Porqueres et al. in 2017 published a study protocol for high-energy laser treatment in rhizarthrosis, which involved randomization to experimental treatment or placebo, but to date the results have not been disclosed. Cantero-Téllez and colleagues (2020) treated 43 patients with rhizarthrosis, randomizing them to an experimental group (high-energy laser) or placebo. They found a remission of pain at the end of high-energy laser treatment, noting, however, that the benefits subsided within 12 weeks. Guo and colleagues (2023) also randomized 42 patients with rhizarthrosis to high-energy laser treatment with occupational therapy guidance or to short-wave treatment and orthosis; their experience has shown that experimental treatment with high-energy laser allowed for improvement in pain and pinch function of the thumb at 12 weeks. The aim of our study is to further investigate the therapeutic effectiveness of high-energy laser treatment in hand osteoarthritis.
