Hydrotherapy for Health in Boys and Adolescents With Duchenne Muscular Dystrophy

The quality of life in young males with Duchenne muscular dystrophy (DMD) is negatively impacted by daily pain, changes in body composition and a lack of support to undertake physical activity. Hydrotherapy represents a potential means of involving boys and adolescents with DMD in activity that could benefit the negative factors influencing their quality of life. There are presently no guidelines or evidence for the benefits of hydrotherapy with the standards of care for young males with DMD.

This trial will provide evidence that will allow care providers to advocate the use of hydrotherapy within the management of DMD, as an inclusive activity, that can be adopted by those with DMD who are either ambulatory, or non-ambulatory. Through 12-weeks of hydrotherapy, the trial will investigate whether there are benefits to physical function, pain and quality of life. These measures represent meaningful outcomes in the progression of DMD, and have direct patient impact for those affected by DMD. On completion of the hydrotherapy, there will be a series of interviews with some of the participants and their parents. The aim of these interviews is to understand participant and parent barriers to hydrotherapy, and uncover whether hydrotherapy improves the lives of the participants beyond simple clinical measures and questionnaires.

The study aims recruit 44 boys and young men with Duchenne muscular dystrophy. Patients will be recruited from NHS neuromuscular services and through families who attend the local hospice.

Following an informed consent process they will enter the first 12 week stage, as a control to observe and measure their habitual physical activity, along with monitoring their diet. They will then enter the intervention stage where they will have a weekly physiotherapy led pool session with a number of physical activities. During the hydrotherapy period, participants will access the hydrotherapy pool once a week for 12 weeks. Sessions are supervised by an experienced physiotherapist, who will guide the exercise for a session lasting 30 to 60 minutes.

The exercises, intensity and specific hydrotherapy plan will be derived from consultation with the participants and their parents. Due to the variance within the presentation of the condition, and the inclusive age range within the study, an externally valid approach to exercise prescription will be utilised. Diet and physical function will be measured during this stage.
