About
Individuals with wrist osteoarthritis (OA) can suffer from pain, muscular weakness, and impaired motion of the wrist, which can reduce the quality of life. While there is strong evidence that all patients with OA should receive first-line treatment with education and exercises, this approach has not yet been proposed for individuals with wrist OA. Therefore, this trial aimed to evaluate the effectiveness of a first line neuromuscular joint protective exercise therapy program compared to a training program with range of motion (ROM) exercises in patients with wrist OA.
Full description
Background: Post-traumatic wrist OA develops slowly, and the joint degeneration may eventually lead to pain, muscular weakness, and stiffness of the wrist. As a result, this can affect the function of the entire upper limb, which can interfere with activities of daily living and the ability to work; thus, leading to reduced quality of life. A progress of disproportionate joint load and disturbed neuromuscular control are frequently present and may even make the condition worse.
Exercise therapy has been defined as a regime of physical activities designed and prescribed for precise therapeutic goals, aiming at educating the performance of specific exercises to improve neuromuscular control, reduce pain and achieve functional joint stability.
Self-management programs, including exercise therapy and joint protective strategies, are core treatments in knee and hip OA. Since the complex wrist joint cannot fully be compared to larger weight-bearing joints as the knee and hip, there is a need to develop exercise therapy programs specially designed for the wrist. Such a program should be part of a comprehensive joint protective standard care and could be beneficial to decrease disability and postpone, or possibly even eliminate, the need for surgery in individuals with wrist OA.
Aim: This is a randomized controlled trial (RCT) with the aim to investigate if a self-managed exercise therapy program with joint protective strategies to improve neuromuscular control (intervention group) will reduce pain and improve function more compared to a training program with range of motion (ROM) exercises (control group).
Material and methods: This study is a single-blinded randomized controlled trial (RCT) in patients with symptomatic and radiographically verified wrist OA with two treatment arms. The participants will be randomly assigned either to an exercise therapy program (intervention group) or to a training program including ROM exercises only. The participants in both groups will receive structured education on 1) wrist anatomy; 2) pathophysiology; 3) joint protective self-management strategies and 4) management of pain and fatigue by exercises.
Both program will consist of home exercises twice a day for 12 weeks. The treatments will be followed up by the treating physiotherapist at the department of hand surgery in Malmö, Sweden at 2-, 6- and 12-weeks post baseline, and the participants will be contacted by telephone at 4 and 8 weeks post baseline. Assessments will be performed at baseline and at 3, 6, and 12 months after baseline by an independent assessor, who is blinded to the participants' group allocation. At the 3- and 6-months follow-up, the participants will rate their global rating of change (GROC) regarding how they perceive their wrist pre- and post-training.
