Horticulture therapy and nature-based interventions represent a holistic approach to rehabilitation in corticobasal syndrome (CBS) and progressive supranuclear palsy (PSP). These interventions leverage the therapeutic properties of natural environments, plants, and garden-based activities to address motor, cognitive, and psychological symptoms in patients with 4R-tauopathies[1][2].
This section covers the evidence base, mechanisms, and practical implementation of horticulture therapy, garden-based rehabilitation, and nature exposure interventions for the 50-year-old male patient with suspected CBS/PSP.
The therapeutic effects of nature-based interventions operate through multiple pathways:
Nature-based interventions engage several neurobiological pathways relevant to CBS/PSP:
| Mechanism | Relevance to CBS/PSP |
|---|---|
| Reduced cortisol | May reduce tau phosphorylation stress |
| Increased BDNF | May support neuronal plasticity |
| Reduced inflammation | Addresses neuroinflammation in tauopathies |
| Improved vagal tone | May enhance autonomic function |
| Enhanced GABA activity | May reduce excitotoxicity |
Horticulture therapy is the purposeful use of plants and gardening activities to achieve specific therapeutic goals. For CBS/PSP patients, this includes:
For CBS/PSP patients, gardens should incorporate:
Studies in dementia care facilities demonstrate that horticulture therapy improves:
The green care interventions show particular benefit for patients with behavioral symptoms[3][4].
Garden-based rehabilitation specifically targets functional recovery through structured garden activities:
Shinrin-yoku (森林浴), or forest bathing, originated in Japan and involves mindful immersion in forest environments[5][6]:
Eco-therapy encompasses broader nature-based interventions:
Before implementing nature-based interventions, assess:
| Phase | Duration | Activities |
|---|---|---|
| Introduction | 10 min | Review goals, select activity |
| Warm-up | 5 min | Stretching, joint mobility |
| Main activity | 30 min | Plant care, garden work |
| Cool-down | 10 min | Relaxation, reflection |
| Closure | 5 min | Review progress, plan next session |
| Phase | Duration | Activities |
|---|---|---|
| Center | 15 min | Orientation, breathing exercises |
| Slow walk | 30 min | Mindful walking, sensory awareness |
| Sitting | 20 min | Meditation, nature observation |
| Walking | 20 min | Continued awareness |
| Closing | 5 min | Reflection, sharing |
For CBS/PSP patients, implement additional safety measures:
For the 50-year-old male patient with suspected CBS/PSP:
Indoor plants: Begin with low-maintenance plants for room
Window garden: Container gardening on balcony or windowsill
Nature videos: If outdoor access limited
Nature-based interventions complement other CBS/PSP treatments:
| Combined With | Potential Benefit |
|---|---|
| Physical therapy | Enhanced outdoor exercise |
| Occupational therapy | Functional garden activities |
| Speech therapy | Outdoor communication practice |
| Music therapy | Nature sound integration |
| CBT | Nature-based mindfulness |
