Exercise is highly recommended while taking into account the persons physical capabilities and stability, carers' close supervisory capacity and environmental safety. Remembering all the while that a person with Angelman Syndrome cannot adjust their own internal thermostat adequately and close attention must be taken of the risk of over-heating and/or dehydration. Be aware of restrictive or excessive clothing during activities and modify same. Running and jumping are not recommended due to the unsteady wide gaite and the high risk of falls. Walking over flat, safe terrain, rowing on a rowing machine, treading water/swimming in a safe level of water with good supervision at hand, ball play for hand-eye co-ordination, gentle group aerobic exercises, bowing bubbles with a bubble pipe to strengthen/exercise mouth muscles, mimicking tongue exercises as recommended by speech therapist. A good OT should be able to advise on further age-appropriate activities. Ensure supervision and safety at all times
