Physiotherapy methods in cerebral palsy
Stretching, range of motion and strengthening exercises are essential in all children. In addition, neurofacilitation techniques stimulate the central nervous system to establish normal patterns of movement. These neurofacilitation techniques were developed over the years to minimise the neurological impairment and help the healing CNS to reorganize. This has not been possible and the focus of therapy shifted from trying to heal the neurological lesion to increasing motor function. There is no treatment method that can heal the lesion in the CNS. The intact neurons in the brain may substitute for lost function, new synapses may form and reorganisation of neurons take place so that the child gains function as he grows. This process is termed neuronal plasticity. The present neurofacilitation methods stimulate the CNS and accelerate neuromotor maturation through the process of neuronal plasticity. The Vojta method is common in Eastern Europe whereas the neurodevelopmental training technique established by B. Bobath and named after her is widely used in the Western world. Both because of difficulties in diagnosing CP in infancy, and the inherent potential of the CNS to heal, it is extremely difficult to judge the actual success of such procedures. Plan the exercises according to the mobility needs of the child. It is not enough to have a therapy session only once during the day with the therapist. Children with CP need to exercise at home to gain maximum function. The success of the techniques used in physical therapy depends on repeated practice. The parents must repeat the exercises with their children every day and observe children for improvement or changes that may be needed.
Conventional exercises
Conventional exercises consist of active and passive range of motion exercises, stretching, strengthening and fitness to improve the cardiovascular condition. Range of motion and strengthening exercises continue for a lifetime in CP, but are especially important in the recovery stage following orthopaedic surgery and in the growth spurt period when risk of contracture formation is maximal. Teach the stretching exercises to the caregiver to prevent contractures. Physiotherapists and parents should be careful with stretching exercises so as not to tear muscle fibers and cause pain, otherwise they will have the opposite effect. Night splints and stretching are not by themselves sufficient to prevent contractures. Strengthening exercises to the antagonist muscles are always necessary because spastic muscles are also weak. Sports activities are helpful in decreasing stiffness and contractures in adolescents using the wheelchair. Cardiovascular conditioning is crucial for the total body involved individual in the wheelchair. Balance is a prerequisite for independent walking, balance training is one of the key reasons for physiotherapy. Strengthening does not affect muscle tone, it does not increase spasticity. On the contrary, the importance of strengthening the spastic muscles and their antagonists cannot be over emphasized for efficient motor function. Do not prevent sitting in the W-position for fear of hip subluxation. W-sitting does not increase femoral anteversion or cause hip subluxation. Children with femoral anteversion sit in a W-shaped position because it is comfortable. When forced to change position for fear of contracture, the child needs to use his hands for balance which interferes with hand function.
