Dynamic water exercise in individuals with late poliomyelitis.

OBJECTIVE: To evaluate the specific effects of general dynamic water exercise in individuals with late effects of poliomyelitis.
DESIGN: Before-after tests.
SETTING: A university hospital department. PARTICIPANTS: Twenty-eight individuals with late effects of polio, 15 assigned to the training group (TG) and 13 to the control group (CG). INTERVENTION: The TG completed a 40-minute general fitness training session in warm water twice weekly. Assessment instruments included the bicycle ergometer test, isokinetic muscle strength, a 30-meter walk indoors, Berg balance scale, a pain drawing, a visual analog scale, the Physical Activity Scale for the Elderly, and the Nottingham Health Profile (NHP). MAIN OUTCOME MEASURES: Peak load, peak work load, peak oxygen uptake, peak heart rate (HR), muscle function in knee extensors and flexors, and pain dimension of the NHP.
RESULTS: The average training period was 5 months; compliance was 75% (range, 55-98). No negative effects were seen. The exercise did not influence the peak work load, peak oxygen uptake, or muscle function in knee extensors compared with the controls. However, a decreased HR at the same individual work load was seen, as well as a significantly lower distress in the dimension pain of the NHP. Qualitative aspects such as increased well-being, pain relief, and increased physical fitness were reported.
CONCLUSIONS: A program of nonswimming dynamic exercises in heated water has a positive impact on individuals with late effects of polio, with a decreased HR at exercise, less pain, and a subjective positive experience. The program was well tolerated (no adverse effects were reported) and can be recommended for this group of individuals.
