When recommending suitable ways for people with Parkinson’s disease (PD) to increase their physical activity, healthcare professionals and caregivers often base their advice on observable motor impairments. Yet we might also consider the dimension of happiness. A 66-year-old former professional water polo player with longstanding PD felt completely freed from his symptoms while swimming, with a sustained post-exercise benefit. His experience in the water was a feeling of happiness. He noticeably worsened on days when he did not swim. However, objective video analysis found no corresponding motor improvement during swimming, which remained significantly impaired due to poor interlimb coordination and ineffective leg movements. This discrepancy underscores the importance of recognising meaningful subjective benefits, including reduced tension and stress that may not be captured by motor assessments alone. In addition to safety concerns, including drowning risk during swimming, exercise recommendations should also consider subjective patient-reported benefits.
