Spasticity in the leg muscles can interfere with mobility, seating, and transfers, such as from bed to wheelchair or from sitting to standing. Spasticity may make it difficult to sit comfortably, or to change positions frequently enough to prevent joint pain and pressure sores. Spasticity in the feet can prevent comfortable fitting of shoes. Severe spasticity may cause painful joint misalignments. A contracture is an abnormal joint posture due to persistent muscle shortening.
Contracture is one of the most significant consequences of spasticity.
When a muscle is not regularly put through its full range of motion, its tendons shorten. This makes stretching the muscle even more difficult, setting up a vicious cycle of even more shortening and decreased stretch. The muscle may develop fibrous scar tissue, further preventing full range of motion. The end result of untreated contracture is a permanent, often painful, abnormal posture. Yes, although it is important to note that in some cases, no treatment is necessary or desirable.
