Arthritis and Exercise THE ESSENTIALS The role, benefits and outcomes of exercise for hip and knee osteoarthritis and rheumatoid arthritis Arthritis and Exercise: The Essentials ABSTRACT Objective The paper was drafted by members of the Both in Australia and worldwide, Arthritis Australia’s Expert Advisory Panel, osteoarthritis and rheumatoid arthritis and reviewed and revised by all panel are major causes of disability and chronic members until consensus was reached. pain. Research has established exercise as Arthritis Australia’s Board, Scientific Advisory a safe and recommended treatment for Committee and Affiliate Healthy Lifestyle these arthritides. Despite evidence and Coordinators all reviewed the paper and clinical guidelines, both consumers and provided further input. health practitioners report confusion and uncertainty around the prescription of, and Results participation in, exercise. Five core components of effective exercise The purpose of this paper is to programs were identified and explored: provide clear, evidence-based practical assessment; education; exercise prescription; recommendations about the role of exercise monitoring and reporting; and behaviour in the management of osteoarthritis change strategies. Evidence for each and rheumatoid arthritis as a guide for was reviewed, summarised and practical consumers, health professionals and recommendations made. exercise & fitness professionals. These recommendations will also underpin the development of criteria that can be used Conclusions to evaluate whether current and proposed Substantial evidence supports the key role community exercise programs are suitable of exercise in the successful management of for people with these arthritides. osteoarthritis and rheumatoid arthritis. By compiling evidence-based recommendations Methods on exercise for these forms of arthritis, this Arthritis Australia established an expert document provides a national resource for advisory panel to guide the process. A consumers, health professionals and exercise narrative review of current literature was & fitness professionals to guide exercise conducted, focusing on Cochrane and prescription and evaluate whether current systematic reviews including meta-analysis of and proposed community exercise programs results available up to April 2014. are suitable for people with arthritis.

Worldwide, arthritis is a major cause of disability Yet significant confusion about the benefit and and chronic pain. In Australia in 2012 there safety of exercise for people with arthritis still were an estimated 6.1 million people with exists within the community, reflected in the arthritis and other musculoskeletal conditions, large number of exercise-related calls to our of which 1.9 million have osteoarthritis (OA) national Arthritis Helpline. Health consumers and 0.5 million have rheumatoid arthritis (RA). frequently report fear of exacerbating This prevalence is predicted to rise substantially, symptoms, and a lack of knowledge about particularly for OA, as the population ages what to do and how to get started, ultimately and rates of obesity increase [2]. By 2032 resulting in lower than optimal levels of physical it is projected that 8.7 million Australians activity. Australian GPs have also told us, via our will have arthritis and other musculoskeletal Voice of GP survey [1], that they lack confidence conditions, an increase of 43% [2]. Arthritis and in prescribing the most appropriate exercise for musculoskeletal conditions have been identified their patients who have arthritis. Recognising by the Australian Government as a National this uncertainty, Arthritis Australia has worked Health Priority Area since 2002 [2]. with a group of experts to bring together this Osteoarthritis and RA can both be extremely guide for consumers, health professionals and debilitating, with pain and physical dysfunction exercise & fitness professionals. leading to significant loss of quality of life. Its purpose is to provide clear, evidence- People with OA and RA report pain, difficulty based recommendations about the role of performing activities of daily living, sleep exercise in the prevention of arthritis and problems and fatigue. They present with ongoing management of individuals with the a range of physical impairments including condition. These recommendations will drive joint stiffness, muscle weakness, altered the development of criteria that can be used proprioception, reduced balance and to evaluate whether current and proposed gait abnormalities. In addition to these, community exercise programs are suitable for psychological impairments such as depression people with arthritis. and anxiety are common. There is no cure for hip or knee OA, and joint replacement surgery We hope that by pulling together this is a costly treatment option reserved for severe information we can offer a significant disease. The direct health care cost of OA opportunity for the fitness industry to link and RA combined in Australia in 2012 was with health sector professionals such as estimated at $4.25 billion. In addition to this physiotherapists and exercise physiologists. For cost is the significant loss of productivity, carer these allied health professionals we believe costs, travel costs and aids [2]. that creating and strengthening referral pathways into suitable evidence-based exercise programs will greatly assist the overall objective ARTHRITIS AND EXERCISE 5 THE ESSENTIALS 2. The role of exercise for cure for RA. Clinical guidelines recommend arthritis regular participation in exercise alongside pharmacological treatments [12-15].

All current clinical guidelines [4-8] recommend However, while exercise is recommended for exercise in the management of hip and RA, the evidence base is still relatively limited knee OA, irrespective of patient age, joint (Table 1).

A 2009 sequential analysis and network meta-analysis Cochrane review of dynamic exercise programs found that since 2002 sufficient evidence has (aerobic training and/or strength training) been accrued to show the significant benefits in patients with RA, which included 8 trials of exercise interventions over no exercise (575 participants), concluded that there was control for lower limb OA [9]. However, most moderate quality evidence that aerobic training of the evidence about the effects of exercise combined with muscle strengthening had a relates to osteoarthritis at the knee with fewer positive effect on aerobic capacity, functional trials investigating osteoarthritis at the hip.
