Peggy FisherPeggy Fisher –  Physiotherapist
B. App Sc (Physio)

Peggy has worked in the practice or consulted to Northern Beaches Physiotherapy for more than 15 years. She has also worked at ADHC early intervention and school age programs for children developmental disorders (Fisher Rd Special school in Dee Why) for 25 years treating and encouraging children with all range of movement issues.

She has extensive experience in minor movement disorders/abnormalities through to very serious problems associated with cerebral palsy, neuromuscular conditions and many other genetic disorders.

We are privileged to have Peggy still consulting with us for children with movement dysfunction. Her wealth of knowledge and experience in recognising, diagnosing and treating children with movement dysfunction is irreplaceable.

Peggy will work with parents and care givers, discussing their concerns. She knows these adults are the most likely to pick up minor problems with children’s movement patterns and encourages parents and care givers to have children assessed early to prevent small imbalances becoming a bigger issue,

Children with early balance issues are more likely to be overly cautious leading to lack of enthusiasm in participation in more challenging tasks and can affect confidence in kids.

Balance and movement control issues are best addressed prior to school age as they can lead to/have an effect on fine motor or pencil (handwriting) control.

In Peggy’s hands children will be given guidance to develop the skills of balance and control in a fun, play themed way.  Parents and care givers will be shown how to continue at home so progress is continuous.

A referral to Peggy is not necessary so if you have concerns about how your baby is rolling or crawling, a clumsy toddler, or a school age child with balance issues, phone for an appointment.

Peggy can also help with Torticollis (when a baby’s  head turns one way predominantly), flat feet, knock knees, sporting issues or injuries.
