contracture prevention and management
Leave a joint in the same bent position long enough — a hand kept in a fist, a knee left flexed in bed — and something quiet and permanent happens: the muscles, tendons, and the tissue around the joint slowly shorten and stiffen until the joint can no longer be straightened, even by force. That fixed shortening is a contracture, and the whole craft of preventing it, and unwinding it early when it starts, is one of the most quietly important jobs in rehabilitation, because a contracture, once truly fixed, is hard and costly to reverse.
Contractures form whenever a joint is held short and not moved through its full range — and several rehabilitation patients are at high risk: a paralysed limb that cannot move itself, a spastic limb constantly pulled into a posture, a painful joint the person guards, a sedated patient in intensive care. The defining test of a true contracture is that the joint will not reach full range even when the person is fully relaxed or anaesthetised, which separates it from spasticity (which eases when you move slowly). Prevention is the heart of the matter: move every joint through its full range daily, position limbs in lengthened rather than shortened postures, splint at risk joints, treat the spasticity that is pulling them, and mobilise early. Once one is forming, the same tools intensify — sustained stretch, night splints, serial casting — and only a long-standing, hard contracture is handed to surgery.
This matters because a contracture is the expensive, avoidable end-point of unmanaged tone and immobility. It blocks function (a hand that cannot open, a knee that cannot straighten to stand), wrecks positioning and hygiene, and causes pain and pressure sores. The honest lesson threaded through this whole field lands here: the cheapest, most effective treatment is the one given before the contracture exists — daily range of motion and good positioning — which is exactly the care most easily skipped when a ward is busy.
A man lies in intensive care, sedated and unmoving, his ankles drooping into a pointed position under the weight of the bedsheets. A nurse props his feet against a footboard and the team moves every joint through its range twice a day — simple, dull work that quietly prevents the foot contractures that would otherwise stop him standing when he recovers.
Daily range of motion and good positioning prevent the costly, hard-to-reverse fixed contracture.
A true fixed contracture does not ease when the limb is moved slowly or relaxed — that is what separates it from spasticity. Treating fixed shortening with antispasticity drugs alone wastes time the joint does not have; the answer is mechanical lengthening.
