Rehabilitation Outcomes and Caregiver Stress in Elderly Patient with End-Stage Parkinson’s Disease

The objective was to evaluate the impact of a 3-month comprehensive rehabilitation program on functional outcomes and caregiver burden in a 73-year-old male with end-stage Parkinson’s disease (PD) following pallidotomy. Baseline evaluation included cardiorespiratory, digestive, and neuromusculoskeletal assessments, complemented by a multidomain geriatric assessment: activities of daily living (Barthel Index), cognition (MoCA), nutrition (MNA), mental health (GDS, UCLA Loneliness Scale), sarcopenia (AWGS criteria), frailty (Clinical Frailty Scale), fatigue (FSS), mobility (De Morton Mobility Index), fall risk (Morse Fall Scale), and caregiver burden (Zarit Burden Interview). The patient then underwent a structured 3-month rehabilitation program consisting of strengthening and flexibility training, cardiopulmonary endurance exercise, functional task practice, and psychological and nutritional counseling, with monthly evaluations. At baseline, the patient presented with generalized rigidity, fatigue, low cardiorespiratory endurance, total ADL dependence, malnutrition, sarcopenia, frailty, loneliness, and high caregiver burden, but intact cognition and mood. After rehabilitation, he achieved short distance walking, improved appetite and weight gain, and reduced scores in Zarit Burden, Fatigue Severity Scale, and MNA. Functional independence (Barthel Index) and respiratory capacity (single-breath count) improved, while frailty and sarcopenia remained stable without progression. In advanced PD, comprehensive rehabilitation can yield meaningful gains in mobility, nutrition, and functional independence while alleviating caregiver burden. Frailty and sarcopenia remain strongly associated with disease progression and highlight the need for sustained multidisciplinary care for both patients and caregivers.
