When refering to evidence in academic writing, you should always try to reference the primary (original) source. That is usually the journal article where the information was first stated. In most cases Physiopedia articles are a secondary source and so should not be used as references. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article).

Most common clinical presentation of RA is polyarthritis of small joints of hands: proximal interphalangeal (PIP), metacarpophalangeal (MCP) joints and wrist.
The hand is one of the main elements of the rehabilitation of patients with rheumatoid arthritis (RA) due to deformities, which occur in approximately 90% of patients.
It is a serious problem, both in the psychological and functional aspect, connected with muscle strength reduction, a limited range of motion and non-acceptance of the changes in the shape of the limb.[1]
Adults with RA should have access to specialist physiotherapy, with periodic review (NICE guideline)[2]
Clinically Relevant Anatomy
The hand contains a complex range of structures which permit a wide variety of movements, many of which are essential for day-to-day tasks. For anatomy see Wrist and Hand
Like many joints in the body, the joints in the hand are synovial joints. These joints are flexible and surrounded by a thin, pliable membrane called synovium. The synovium produces synovial fluid, a thin, clear, viscous substance that normally nourishes and lubricates the joint, enabling movement. In people who have rheumatoid arthritis, however, the joints of the hand can become inflamed when the body’s immune system malfunctions and attacks healthy tissue in the fingers and wrists.
In addition to encapsulating joints, synovial tissue surrounds most tendons. Rheumatoid arthritis can cause a tendon’s synovial sheath to become inflamed i.e. tenosynovitis. The inflammation is not always painful but can lead to tendon damage.
Over time these changes lead to RA affecting the joints of the hand and wrist including
Wrist joint
Metacarpal joints
Metacarpophalangeal Joint (MCPJ) – condyloid joints comprised of the articulation between metacarpal and proximal phalanx in each of the 5 digits.
Interphalangeal Joints – between the phalanges and there are two in each digit. The thumb is an exception, and has only one interphalangeal joint. The two joints are the:
Proximal Interphalangeal Joints (PIPJ)
Distal Interphalangeal Joints (DIPJ)
Pathological Process
Rheumatoid arthritis (RA) is a chronic inflammatory systemic disease.
The immunological process within the connective tissue contributes to progressive disability.
It starts in the synovial membrane and leads to a gradual deterioration of articular and periarticular structures and deformity development.
Problems which are constantly experienced by RA patients include morning joint stiffness and reduced muscle strength.
The first symptoms are symmetrical carpal and metacarpophalangeal arthritis manifested by pain, oedema, exudate and a limited range of motion.
Progressive hand dysfunction contributes to various limitations in the personal, social and professional aspects of life.
Pain is the dominant symptom reported by patients.
Rheumatic pain is chronic and lasts from the onset of the disease until the end of a patient’s life.[1]
Clinical Presentation
Most common clinical presentation of RA is polyarthritis of small joints of hands: proximal interphalangeal (PIP), metacarpophalangeal (MCP) joints and wrist (other commonly affected joints include wrist, elbows, shoulders, hips, knees, ankles and metatarsophalangeal (MTP) joints).
Most commonly joint involvement occurs insidiously over a period of months, however, in some cases, joint involvement may occur over weeks or overnight.
Stiffness in the joints in the morning may last up to several hours, usually greater than an hour.
On examination, there may be swelling, stiffness, deformity, and tenderness of the PIP, MCP wrist, synovitis, and there may be a decreased range of motion.
Rehabilitation is a long-term process depending on the grade and type of deformity and activity of disease.
Exercises which strengthen muscles and increase joint mobility are beneficial.
Exercise intensity needs to be constantly controlled and adjusted to the activity of disease.
During the exacerbations, the exercises should be performed in hospital or on an outpatient basis under strict supervision of a therapist.
Numerous therapeutic regimens are introduced during the chronic stage. These address both the dysfunctions and individual needs of the patient, including professional activity or hobbies.
Irrespective of the activity of disease, it is extremely important to teach the patient how to behave and perform activities of daily living in a safe way in order to limit excessive joint loading.
The improved function of the hand may be maintained with the continuation of an exercise programme at home. Functional assessment is a basic tool to determine hand dysfunction severity.[1]
