This summary of a Cochrane review presents what we know from research about the effect of stretch interventions for contractures. The review shows that stretch is not effective for the treatment and prevention of contractures. We do not have precise information about side effects. Possible side effects include pain, and skin redness or breakdown. What are contractures and what is stretch? Contractures are characterised by the inability to move a joint freely. Contractures may be a complication of neurological conditions including stroke, spinal cord injury, traumatic brain injury and cerebral palsy. They are also commonly associated other conditions including rheumatoid arthritis, surgery and burns. They interfere with activities of daily living and can cause pain, sleep disturbances and pressure areas, and can also result in unsightly deformities. Stretch is widely used for the treatment and prevention of contractures. The aim of stretch is to increase joint mobility. Stretch can be administered with splints and positioning programs, or with casts which are changed at regular intervals (serial casts). Alternatively, stretch can be self-administered or applied manually by therapists.
