The study took place for 14 weeks, with measures being taken at baseline, seven weeks in, and at the conclusion. The participants were also followed up 6 weeks after the final session. The training program consisted of bi-weekly 1-hour sessions of sports activities. The authors noted that again because the course of PD is so variable, it is hard to determine the "best" physical activity plan for people with PD. The authors do outline various common problems associated with PD (for example, problems with initiation of movement and slow gait) and list various suggested exercise training activities. The activities took place in a pool once per week. PD-specific issues were recorded using the Unified Parkinson's Disease Rating Scale (UPDRS); issues covered in the UPDRS include cognitive function, activities of daily living, and complications of treatment. Several other measures were used to collect various data: the Columbia University Rating Scale (CURS), which measures motor function; the Basic Motor Test (BMT), which measures strength, flexibility, and coordination; the Mini Mental Status (MMS), which measures dementia; the Adjective Mood Questionnaire of Zeersen, which measures mood; and the Sickness Impact Profile (SIP), which measures subjective well-being. No related medical problems occurred during the training program.
