Juvenile Chronic Arthritis
The inflammatory changes involve soft tissues in and around the joints, bones and articular cartilage. The joints most usually affected are those of knees, hips, ankles, wrists, and cervical spine. The condition may affect a single joint or many joints.
The onset of the condition usually occurs at an early age and thus most patients will undergo treatment for a prolonged period of time. Hydrotherapy provides excellent conditions to obviate hurdles to therapy and normal life activities which enrich life, particularly when hydrotherapy exercises can be camouflaged in a program of fun games and group activities which lead on to healing, learning of life skills and general feelings of well being. The warmth of the water provides relief of pain and muscle spasm, and buoyancy relieves the strain on joints, particularity the arthritic weight bearing joints.
The aims of Hydrotherapy are to:
(a) relieve pain
(b) aid relaxation
(c) increase range of movement and muscle strength,
(d) decrease deformity,
(e) improve functional ability.
Children may be referred for hydrotherapy while still on bed-rest as they become able to exercise in a non weight bearing situation, and stand and walk while partially weight bearing. The therapist must observe the child's shape and density. Alterations in the former will come about due to the pain, muscle spasm and joint changes. Density may he altered due to the loss of muscle bulk which can result from the decrease in use first caused by pain. In practice, it is advisable to introduce the child to the water gently and quietly at first, observing all the points of handling and entry. The young child in pain will be anxious about going into water and may exhibit fear. A one-to- one relationship within a group situation is desirable, but at first care should be taken to avoid joining a group that contains other extremely active children.
An awareness of which joints are most affected is important, and activities directed towards exercising them and strengthening the muscles surrounding them must be selected. As with all children and all water activity, it is advantageous to encourage blowing onto, and into, the water from the earliest time because in addition to the effects on respiration, such action induces the forward movement of the head and encourages flexion of neck and trunk. The range of abduction and adduction of the hip joints may need to be increased and muscle power strengthened If the child is non-weight-bearing due to pain in the hip joints, these can be exercised in supine lying supported by the therapist at the center of balance of the body, with the head resting on the therapist's shoulder.
Increasing Muscle Weakness
If the child is less and less able to create movement in the water, particularly those movements of vertical and lateral rotation, consequently the child is at greater risk and care must be taken to ensure safety. Facilitation of rolling and forward recovery eventually becomes necessary.
As muscle changes take place, so the density of the child alters and there will be a tendency for those parts, which have become less dense, to float higher. Floating is usually easy for the child but, for comfort, happiness and safety, floating should be in the supine position.
