The goal of this clinical trial is to learn if a nature-based program has positive effects on the physical and psychosocial health in a group of participants with Parkinson's disease. The main questions it aims to answer are:
Will the program improve:
Participants will:
The chronic and neurodegenerative disease of Parkinson's (PD) is often characterized by movement and balance disorders, which are accompanied by an increased risk of falls. Falls are one of the most common problems that can lead to subsequent injuries (e.g., femoral head fracture) and associated mortality rates. Falls are frequent, debilitating, and have deleterious effects on self-confidence and the quality of life of individuals with PD. Additionally, according to Parkinson Canada, a high proportion of individuals living with this disease suffer from depression and/or anxiety. Therefore, it is essential to implement intervention programs aimed at improving the physical and functional capacity as well as the well-being of this population to prevent falls and promote sustainable health.
In recent years, an increasing number of studies have demonstrated the benefits of contact with nature on the physical and mental health of individuals. Specific and positive effects on psychological symptoms (e.g., depression) as well as cognition (memory) in adults have also been shown according to this recent evidence. This stimulates our research team to test the effects of a physical intervention in nature on the physical and mental health of individuals suffering from PD. One of the perspectives of this new intervention in nature is also to evaluate its impact on fall risks in this population. The ultimate goal of this project is to contribute to the sustainable health of the population.
The overall objective of this project, based on a pilot study, is to assess the effects of an 8-week nature-based intervention program on the physical and mental health of individuals with PD. Various physical measures (mobility, strength, and balance) and mental measures (level of depression, stress) will be studied in this project to better understand the effects of this type of intervention.

The Social Provisions Scale-10 (SPS-10) is a shorter version of the original Social Provisions Scale (SPS). It is a brief self-report questionnaire designed to measure perceived social support across five dimensions. The SPS-10 is derived from the longer SPS but consists of a subset of items that capture key aspects of social support. Similar to the original SPS, respondents rate their agreement with each item on a Likert scale, ranging from 1 (strongly disagree) to 4 (strongly agree). The SPS-10 provides a quick and efficient way to assess an individual's perceived social support network and their satisfaction with various aspects of their social relationships. |
| change from baseline at 0 to 8 weeks |
| Connection to nature (CNS) | The Connection to Nature Scale (CNS) is a psychological assessment tool designed to measure an individual's subjective connection to nature. It evaluates the degree to which people perceive themselves as a part of the natural world and the extent to which they appreciate and value nature in their lives. Respondents are asked to rate their agreement with each statement on a Likert scale, ranging from 1 (strongly disagree) to 5 (strongly agree). The scores are then totaled to provide an overall measure of an individual's connection to nature. | change from baseline at 0 to 8 weeks |
| 5 times Sit-To-Stand (FTSTS) |
f the 30 second sit to stand test was not applied for some patients, we used also this test which it measures the amount of time it takes for a patient to sit and stand five times in succession with arms folded across their chest. 2 trials were applied in this test and the best time in seconds used for analysis. |
| change from baseline at 0 to 8 weeks |
| Maximal isometric hand grip strength | Jamar dynamometer to assess maximal isometric hand grip strength and frailty criteria. 3 trials of maximal contraction up 5 seconds. The best value was retained and corrected by body mass index from Fried classification. | change from baseline at 0 to 8 weeks |
| Number of falls | Self-reported falls before, during and after the study | change from baseline at 0 to 8 weeks |
| Trunk postural control on wobble chair | This test measures trunk postural balance during a sitting balance task on an unstable chair where only lumbar spine movements are allowed to restore balance. Briefly, the base of the chair consists of a pivot at its center and four springs that can be arranged and fixed at a distance varying between 6.0 and 21 cm from the center, allowing the system's level of stability to be varied. The system allows only forward/backward and lateral tilting. | change from baseline at 0 to 8 weeks |
| Frailty criteria from Fried | The presence of frailty criteria according to Fried was assessed with self-report questions and two physical tests from five characteristics : 1) Low physical activity (to capture history of sedentary behavior or activity: ex. Do you get any physical exercise for the sake of exercising? How often do you leave your house?); 2) fatigue (complaint of exhaustion with normal activity such as walking outside, climbing stairs: ex. I felt that everything I did was an effort in the last week?); 3) weight loss (unintentional weight loss 10 lbs. or more in past year or more than 5% in past year); 4) weakness (grip strength evaluated with manual dynamometer; in average <30 kg for men and <18 kg for women, but data is normalized by body mass index); 5) slowness or slow walking speed (usual gait speed over 4.57 meters (15 feet); ex. >6.5 seconds, dependent of height). | change from baseline at 0 to 8 weeks |
| Hoehn and Yahr Scale | It is a five-point scale used by doctors and researchers to rate the degree of disability and severity of symptoms caused by Parkinson's disease: Stage 1: Unilateral involvement only Stage 1.5: Unilateral and axial involvement Stage 2: Bilateral involvement without impairment of balance Stage 2.5: Mild bilateral disease with recovery on pull test Stage 3: Mild to moderate bilateral disease; some postural instability; physically independent Stage 4: Severe disability; still able to walk or stand unassisted Stage 5: Wheelchair bound or bedridden unless aided | Only at baseline from Sample characterization when Parkinson was included |
| Cognitive status | Mini-mental state questionnaire (MMSE or Folstein), which is used for grading the cognitive state of patients in this study. It's assessing the attention and orientation, memory, registration, recall, calculation, language and ability to draw a complex polygon. It is ranged from 0 to 30, where 30 means no impairment. | Only at baseline from Sample characterization |
