Exercise for hand osteoarthritis.

Area of Science:

• Rheumatology
• Physical Therapy
• Osteoarthritis Research

Background:

• Hand osteoarthritis (OA) is a common condition causing pain, stiffness, and functional limitations.
• Current treatments focus on non-pharmacological approaches, but exercise efficacy for hand OA remains unclear.
• Existing evidence for exercise in hip and knee OA suggests benefits, prompting investigation into hand OA.

Purpose of the Study:

• To evaluate the benefits and harms of exercise interventions for individuals with hand OA.
• To compare exercise against placebo or no intervention in managing hand OA symptoms.
• Primary outcomes assessed were hand pain and hand function.

Main Methods:

• Systematic review and meta-analysis of randomized controlled trials (RCTs) comparing therapeutic exercise to control groups.
• Searched six electronic databases up to September 2015.
• Data extraction, risk of bias assessment (e.g., Cochrane's Risk of Bias tool), and GRADE approach for evidence quality were performed by two independent reviewers.

Main Results:

• Low-quality evidence from five trials (381 participants) indicated exercise reduced hand pain (SMD -0.27) and finger joint stiffness (SMD -0.36).
• Four studies (369 participants) showed exercise improved hand function (SMD -0.28), but effects were not sustained at medium- and long-term follow-up.
• Evidence regarding quality of life was uncertain, and reported adverse events were few and not severe, though an increased likelihood of adverse events and withdrawals was noted (RR 4.55 and 2.88, respectively).

Conclusions:

• Exercise demonstrates small, short-term beneficial effects on hand pain, function, and stiffness in hand OA, based on low-quality evidence.
• The clinical significance of these small effect sizes is debatable, and long-term benefits were not observed.
• Further research is required to clarify the optimal exercise protocols and confirm the safety and efficacy of exercise for hand OA management.
