Brief summary

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: * The physical outcomes such as mobility, strength and balance? * The psychosocial health outcomes? Participants will: * Be assessed before and after the program; * Participate in one session per week of the intervention.

Detailed description

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.

Design outcomes

Primary

MeasureTime frameDescription
Depression state (PHQ-9)change from baseline at 0 to 8 weeksThe Patient Health Questionnaire-9 (PHQ-9) is a self-administered tool used to screen, diagnose, monitor, and measure the severity of depression. It consists of nine questions based on the diagnostic criteria for major depressive disorder in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition).Respondents rate how often they have experienced each symptom over the past two weeks on a scale ranging from 0 (not at all) to 3 (nearly every day). The scores are then added together to produce a total score ranging from 0 to 27, with higher scores indicating greater severity of depressive symptoms
Well-being state (WHO-5)change from baseline at 0 to 8 weeksThe World Health Organization Well-Being Index (WHO-5) is a widely used self-reported questionnaire designed to measure subjective well-being. It assesses the individual's overall psychological well-being and quality of life. The WHO-5 consists of five simple questions that ask respondents to rate their well-being over the past two weeks. The questions cover aspects such as positive mood, vitality, and general interest in life. The questionnaire is scored on a scale from 0 to 100, with higher scores indicating better well-being.
Connection to nature (CNS)change from baseline at 0 to 8 weeksThe 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.
Postural controlchange from baseline at 0 to 8 weeksMeasures of center of pressure (COP) from plateform of force during different balance tasks
Walkingchange from baseline at 0 to 8 weeksGait parameters from GaitRite measurement The participants will be asked to walk at normal and fast speeds on a GaitRite treadmill (GAI-TRite® Platinum) Plus System 16' - 4.876 m, SN: Q209, CIR Systems Inc., Franklin, NJ, USA). Participants will perform each task twice. Main gait parameters will be used as main outcomes such as velocity in m/s.
Social Provisions (SPS-10)change from baseline at 0 to 8 weeksThe 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.

Secondary

MeasureTime frameDescription
Number of fallschange from baseline at 0 to 8 weeksSelf-reported falls before, during and after the study
Functional mobility test (TUG)change from baseline at 0 to 8 weeksTo assess mobility. Equipment: A stopwatch. Directions: Patients wear their regular footwear and can use a walking aid, if needed. Begin by having the patient sit back in a standard arm chair and identify a line 3 meters, or 10 feet away, on the floor.
5 times Sit-To-Stand (FTSTS)change from baseline at 0 to 8 weeksf 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.
Maximal isometric hand grip strengthchange from baseline at 0 to 8 weeksJamar 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.
Trunk postural control on wobble chairchange from baseline at 0 to 8 weeksThis 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.

Other

MeasureTime frameDescription
Falls Efficacy Scale-International (FES-I)change from baseline at 0 to 8 weeksThe Falls Efficacy Scale-International (FES-I) is a short, easy to administer tool that measures the level of concern about falling during social and physical activities inside and outside the home whether or not the person actually does the activity. The level of concern is measured on a four point Likert scale (1=not at all concerned to 4=very concerned)
Cognitive statusOnly at baseline from Sample characterizationMini-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.
Hoehn and Yahr ScaleOnly at baseline from Sample characterization when Parkinson was includedIt 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
Frailty criteria from Friedchange from baseline at 0 to 8 weeksThe 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).
