To explore the activity experiences of patients with Parkinson’s disease (PD) after falls. Methods: Thirteen PD patients were recruited from the Department of Neurology of a tertiary hospital in Wuhan, China using the purposive sampling method. Semi-structured interviews were then conducted and the data were analyzed using Colaizzi’s 7-step method. Results: The activity experiences of PD patients after falls were categorized into four main themes: insufficient activity participation, significant cognitive difference in falling awareness, psychological changes after falls, and accumulation of fall prevention experience. Conclusion: Healthcare professionals should encourage PD patients to actively engage in activities while assisting them in recognizing falls and fall risks. Fall prevention strategies can involve adjusting activity modes, seeking assistance from family members, and improving the home environment.
