Abstract
Numerous studies have previously shown that physical activity improves quality of life in patients with Parkinson Disease (PD) in several areas. Between non-motor difficulties, PD patients develop sleep disturbances. Poor reported sleep quality is very common in this condition and it is important to be taken into account because it impacts seriously on daily function. The objective of this study was to assess the effectiveness of an eight weeks exercise program with elastic bands on the subjective quality of sleep in PD patients. A sample including 23 PD patients with more than 21 punctuation in the MiniMental State Examination were recruited from a local association. Each participant underwent an individual assessment. Anthropometric data were measured. Outcomes measures were perceived sleep quality measured with the Pittsburgh Sleep Quality Index (PSQI) and perceived fatigue evaluated with the Piper Questionnaire. The participants were included in an eight weeks-physical activity program with elastic bands during an hour three times per week. The majority of the participants were men (74%) with a mean age of 74.12 ± 6.11 years old. The Geriatric Functional Rating Scale (GFRS) showed a 70% value of functionality. Their Hoen & Yahr score in off condition was I in the 4.3% of participants, II in 17.4%, III in 52.2% and IV in the 26.1%. Pre-to-postintervention significant improvements ( p = 0.011) are important to consider regarding to perceived quality of sleep in total punctuation of PSQI. Significant differences ( p = 0.005) were found in the sleep disturbances subscale, that appear to be reduced after the 8 weeks training program. Perceived fatigue was also significantly better ( p < 0.05) after the exercise program. The participants reported improvements in the areas of behavioural, affective and sensorial fatigue. The exercise program used in this study was safe and effective in order to improve perceived fatigue and quality of sleep in PD patients.
