OA is a common form of [[arthritis]] and it leads to a major health economic burden.

In [[osteoarthritis]], initially there is molecular derangement (interrupted joint metabolism) followed by anatomical and physiological derangements such as cartilage degeneration, osteophyte formation, bone remodeling, joint inflammation and loss of normal function. Clinically the patients present with pain and stiffness in affected joint. Morning stiffness is also present.<ref>Katz JN, Arant KR, Loeser RF.

Introduction[edit | edit source]

Exercise group

Exercise therapy has positive benefits for people with symptomatic Osteoarthritis (OA). OA is a common form of arthritis and it leads to a major health economic burden. It commonly occurs in weight bearing (WB) joints (for example hips and knees), and NWB joints (for example the hands). In osteoarthritis patients present with pain and stiffness in affected joint.[1] [2]The management of OA can be divided in to conservative and conservative[3] treatments. Also, non conservative ( non operative) treatment can be divided to pharmacological and non pharmacological.[3]

Exercise therapy is the core for conservative Treatment,[3]

  1. Muscle strengthening and programs containing combinations of strength, flexibility, and aerobic exercises, mind body exercise like Yoga and Tai Chi are helpful for pain relief ,improving physical function and disability than general activity (e.g., walking).
  2. Exercise therapy brings other benefits, beyond pain and physical function, with moderate effects on depression.
  3. Programs including exercise therapy and education about exercise are recommended to decrease fear of activity and improve patient engagement in exercise programs.[4]See Patient Education in Pain Management.

Obesity, Exercise and OA[edit | edit source]

Obesity: risk factor for OA

Obesity is one of the most significant risk factors for osteoarthritis symptoms and disease progression, especially for the knee involvement.[5][3]

  1. Exercise is beneficial for the maintenance of metabolic homeostasis. Excessive adipose tissue, as occurs in obesity, increases mechanical stresses on weight-bearing joints and additionally generates an imbalance in the secretory profile of adipokines, including leptin, adiponectin, visfatin, and resistin. These conditions create an environment of low-grade inflammation lead eventually to cartilage breakdown.
  2. Clinical trials have shown that exercise programs (consisting of aerobic walking, strength training, a second aerobic phase, then a cool-down period) in combination with diet, led to significant reduction in weight, total fat mass, pain relief, and improvements in mobility.[6][7][8]

NB Knee OA: Obesity also causes thinner medial tibial cartilage compared to normal BMI individuals.[9]

Physiotherapy[edit | edit source]

Therapeutic exercises(type/ dose) are decided by the physical therapist based on the need of the patient and are dependent on age, weight, basic fitness level, severity of the disease and comorbidities.[10][11]

  • Low contact sports are effective to manage OA, it prevents maximum joint stress and improves muscle strength and joint stability. High contact sports are avoided.
  • Mind and body exercises such as Tai Chi and yoga are also prescribed.[12]
  • Gait aids can be recommended.
  • Cryotherapy can be used as an adjunct along with land based exercises.[13]
  • Education on weight management has to be provided.
  • In electrotherapy, Transcutaneous Electrical Nerve Stimulation is applied.[14]
  • Balance Exercise [3]

Optimal exercise prescription will lead to exercise adherence reduce the risk of symptom flare up and maximize the outcome. See Adherence to Home Exercise Programs

Aquatic Exercises[edit | edit source]

Hydrotherapy

The exercises which are performed in water are known as aquatic exercises or hydrotherapy. It has various advantages in comparison to land based exercises. Blood circulation is improved by constant water temperature and hydrostatic pressure, it reduces the tension of soft tissue contracture. It even helps in reducing muscle spasm and fatigue. Muscle strengthening is promoted as water resistance acts in opposite direction of the body motion, which needs greater muscle activity. The buoyancy reduces the weight bearing which helps in reducing the degradation of the joints. It also give a soothing environment for osteoarthritis patients who are reluctant towards exercise.[15]

OA Hand[edit | edit source]

Hand OA

Osteoarthritis of hand is a common musculoskeletal disease. Its prevalence is rising rapidly with increasing age. It is usually occurs in 1st carpometacarpal joint. [16]The clinical features are hand pain, stiffness, reduced grip strength and compromised functional status. The primary goal of a physiotherapist will be to manage pain and improve the functional status by working on strength of the muscles.[17]Hand orthosis are strongly prescribed.[16]

European League Against Rheumatism Recommendations for Hand OA

  • Education and training in ergonomic principles ,pacing of activity and use of assistive devices should be offered to every patient.
  • Exercises to improve the function and strength and to reduce pain should be considered by the therapist.
  • Orthoses should be prescribed in thumb base OA for symptom relief.
  • Long term follow up of patients with hand OA should be as per the patient's requirement. [18]
