Jack is a young man of 19 with multiple disabilities including Spinal Muscular Atrophy, Autism Spectrum Disorder, Intellectual Disability as well as having his right hip removed aged 14 due to sepsis. One of Jack's goals is to reduce his risk of further contractures and maintain current range of motion and function in his upper and lower limbs. It is important for Jack to maintain a regular exercise routine.  Jack works closely with an OT and exercise physiotherapist to help achieve this goal. The challenge for Jack and his therapists is that Jack struggles to hold himself upright when in the pool, and requires the exercise physiotherapist to physically support his body. This compromises the exercises Jack can do in the pool and as such his pool exercise sessions suffer. Jack and his physiotherapist would like a solution that helps Jack support his body in the water independently while allowing the exercise physiotherapist to perform the exercises with Jack.
