Final answer:
Serial casting is a procedure used to gradually improve joint flexibility and reduce muscle spasticity in clients with increased muscle tone by applying a series of casts that hold the joint in a stretched position over time.
Step-by-step explanation:
Serial casting works by applying a series of casts to gradually stretch muscles and tendons. The casts are used to hold a joint, such as the ankle, wrist, or elbow, in a stretched position for an extended period. This method is based on the principle that providing a continuous low-force stretch can reduce muscle spasticity and improve the range of motion over time. It's particularly effective in clients with increased tone, also known as hypertonia, where muscles are continuously contracted.
Serial casting involves changing the casts frequently, usually every week or so, to allow for further stretching as the muscle adjusts and the range of motion improves. This treatment is especially beneficial for individuals with neurological conditions like cerebral palsy, where increased muscle tone can cause joint stiffness and functional impairment.
To answer the question specifically, the correct option is C: Serial casting involves the use of multiple casts to gradually improve joint flexibility and reduce muscle spasticity.
