HYDRO-DMD research study
Hydrotherapy for Duchenne Muscular Dystrophy (DMD): a pilot and feasibility randomised controlled trial in children.
Physiotherapy is thought to help children with Duchenne muscular dystrophy (DMD) stay physically active.
Aquatic therapy (hydrotherapy), physiotherapy in warm water, allows exercise and stretching which are not possible on land. It is not clear that aquatic therapy works, so NHS access is limited. This pilot study was funded to see if a controlled trial of aquatic therapy for DMD was feasible.
We wanted to enrol 40 children with 20 having aquatic therapy. If we succeeded, we could say that a full-scale study was feasible.
Mixed methods feasibility study incorporating external pilot RCT, qualitative case study, cost-impact analysis. All children were asked to do stretching and exercise at home.
We planned that half would have aquatic therapy in hospital pools for half an hour, twice a week for six months.
We measured how well they could use their legs at the beginning and end. After this, children, parents and physiotherapists told us how they felt about aquatic therapy and the study.
Lay Summary Video
We screened 348 children with DMD for the study. Only twelve could enter the study. This is too few to show if aquatic therapy works or not.
Those involved said it should be offered nearer to their homes than we managed. Not enough children could be found for a full-scale study run only from hospitals.
Local aquatic therapy programmes should be designed by children, parents, physiotherapists and teaching assistants. Standard trial designs may not be feasible. Other research designs might be needed to test aquatic therapy.
What people said
Some children who had aquatic therapy felt better
"I couldn’t jump and now I can" (Child)
"the next day the body is more refreshed … it was nice way to start the day" (parent)
But some didn't improve.
"Unfortunately, I couldn’t find any kind of good positive result from hydrotherapy" (parent)
It wasn't just about how well your legs worked...
“He really did come out of himself and be excitable in the pool and actually chat to the physiotherapists… rather than being the reserved child he often is in public…" (Parent)
One child was very tired and had some pain after the aquatic therapy:
“Well I get really exhausted I feel like I wanna go to bed, but obviously I can’t go to bed because I have to go to school... when I get in class my legs are in a little bit of pain but then, when it’s the afternoon my legs feel better.” (Child)
Travelling to the hospital pools to do aquatic therapy was tough:
"It was probably only fifteen miles each way, but via the school and then rush hour traffic. Bear in mind my session was at four o’clock so sometimes it was an hour and a half on the way back, not a challenge unless you’ve got a five month old screaming baby in the back.”
Physiotherapists had different opinions about aquatic therapy.
"I mean I’ve often said ‘this child needs hydro'... but I think I would be even more dogmatic now and say ‘look it really is a good intervention’."
“All he’s done is get progressively worse and had more and more issues at school with fatigue and I think we’ve affected his quality of life very negatively”
Before our study was neither robust data nor internationally-agreed guidelines on the effectiveness or optimal content of physical therapies for Duchenne Muscular Dystrophy. We created and tested manuals for land-based and aquatic therapy which are publicly available.
