Nine months ago my physiotherapist referred me to an aquatic exercise class at the council-run Leisure Pool. Two half -hour classes a week for twelve weeks, then "promotion" to a more "advanced" class for twelve weeks. Before you start you have an interview with the tutor, who assesses what kinds of exercises will help you most.
The water is about 4 feet deep. You warm up for ten minutes with communal exercises in a large circle, do your own individual exercises for 15 mins, then finish in the circle again.
After eight weeks I began to have the confidence to walk through the water alone without holding on to the side, and after another two weeks joined all the others in the circle. The tutor is excellent, and infinitely patient and encouraging. Fortunately I wasn't turfed out after the twelve weeks, and nine months later I am still in the "elementary" class, and still benefitting from the exercises.
I wasn't expecting any dramatic improvement - just hoping to delay the progression of the CMT. However I really do think my balance is a little bit less dire, while the ability to stand, walk, "jog" (after a fashion, with hardly any forward movement) - and even jump, while supported by the water is a wonderful and liberating feeling.
