MELBOURNE SHOULDER GROUP
MSG is continually involved in the treatment of elite and non-elite tennis players. We pride ourselves on objective, criteria-based pre-treatment and return to sport testing protocols for all our athletes to monitor treatment progress and enhance successful return to play.
Among other tennis-specific treatments, MSG developed and implements the Watson Instability Program (WIP1), the only shoulder rehabilitation program to be tested in a randomised controlled trial and the Watson Posterior instability program (WIP-p), which are paramount in the treatment of micro-instability in tennis players.
Tennis related conditions not appropriate for surgery can be referred our surgical team members for review (Mr Hoy, Mr Barwood), who have years’ experience treating elite and non elite tennis players.
Though our tested rehabilitation programs, ongoing research, appointments at the AO, educational courses and presence on the national and international conference circuit, we aim to continue to disseminate, educate and impact future participants and organizations in tennis.
