New surgical interventions for cerebral palsy and the place of gait analysis

Rehabilitation of spasticity and related problems in childhood cerebral palsy

Spasticity is one part of the upper motor neuron syndrome, but it is a widespread problem in cerebral palsy; it is debilitating, affects function and can lead to musculoskeletal complications. Significant advances have occurred in antispasticity management (and related musculoskeletal problems) in children with cerebral palsy during the past 5-10 years. Botulinum toxin A has been the most outstanding treatment advance; it is relatively long-lasting, easy to administer, reversible, has a favourable side-effect profile and is highly useful for focal spasticity. There is an emerging role for intrathecal baclofen in Australia. Despite being available and practised in North America for years, selective dorsal rhizotomy has not been popular in Australia. The use of orthopaedic surgery has significantly altered in recent years. There is still a place for oral drug treatment, including some newer agents and the potential for combination treatment with other modalities. The role of physical therapy in defining disability, assessing function, undertaking biomechanical assessment and providing mobility aids/casting/orthoses and motor training/stretching exercises is critical for the success of medical and surgical interventions. From an Australian perspective, the purpose of the present review is to provide a critical review of therapies available for spasticity associated with childhood cerebral palsy.

A practical guide to gait analysis

The act of walking involves the complex interaction of muscle forces on bones, rotations through multiple joints, and physical forces that act on the body. Walking also requires motor control and motor coordination. Many orthopaedic surgical procedures are designed to improve ambulation by optimizing joint forces, thereby alleviating or preventing pain and improving energy conservation. Gait analysis, accomplished by either simple observation or three-dimensional analysis with measurement of joint angles (kinematics), joint forces (kinetics), muscular activity, foot pressure, and energetics (measurement of energy utilized during an activity), allows the physician to design procedures tailored to the individual needs of patients. Motion analysis, in particular gait analysis, provides objective preoperative and postoperative data for outcome assessment. Including gait analysis data in treatment plans has resulted in changes in surgical recommendations and in postoperative treatment. Use of these data also has contributed to the development of orthotics and new surgical techniques.

The child with cerebral palsy--clinical considerations and management

Cerebral Palsy (CP) is a non-progressive disorder of the motor system secondary to brain injury during early development. Associated non-motor problems are frequent and contribute significantly to the disability. While spastic CP is the commonest, dyskinetic CP continues to be a problem in our contribute. Acquired CP mostly secondary to CNS infections constitutes a significant proportion of cases in developing countries. Early diagnosis, proper assessment of the functional capacity and needs of the child and providing early intervention are important. A multidisciplinary approach to management with active parental involvement helps the child achieve his potential.
