Effectiveness of physical activity as primary preventive care for lower urinary tract symptoms in elderly people through the "Muscle Enhancing Club".

There was no control group and no random assignment, so the study cannot show that the class caused any change. The class included aerobic exercise, stretch, balance movement, muscle strength exercise, talking about health, and physical fitness tests, so the effect of any single component cannot be separated. The response rate was 61.7%, and men who did not fill the questionnaire were excluded, so the analyzed group may not represent all class attendees. Many symptom scores were tested, and the main whole-group results were mostly null, so the subgroup changes could be chance. Participants were over 65 with no long-term care need, so the results may not apply to frailer older adults. Outcomes were questionnaires with missing data handled item by item, not a clinical assessment of bladder function.

Do not conclude that the Muscle Enhancing Club prevented or treated lower urinary tract symptoms in all older adults. The whole-group results were mostly unchanged, the changes were in people already selected as having symptoms, and the class included aerobic exercise, stretch, balance movement, muscle strength exercise, talking about health, and physical fitness tests, so no single component can be separated.
