Patients with neuromuscular disorders benefit from specialized seating devices that stabilize the trunk and pelvis. Proper fitting guidelines and patient classification are crucial for effective wheelchair seating solutions.
Area of Science:
- Rehabilitation Engineering
- Biomedical Engineering
- Assistive Technology
Background:
- Neuromuscular disorders impair continuous postural adaptation.
- Seating devices (orthoses, cushions) can enhance quality of life by stabilizing the pelvis and trunk.
- Dynamic sitting involves motor reactions of trunk and pelvic muscles influenced by internal and external factors.
Purpose of the Study:
- To establish guidelines for planning and fitting high-quality, cost-effective seating devices.
- To address functional problems and pain associated with inadequate seating.
- To improve patient outcomes through precise indication and fitting of seating solutions.
Main Methods:
- Developing guidelines considering pathomorphologic mechanisms and patient personality.
- Emphasizing teamwork within a seating clinic for goal definition.
- Defining treatment goals based on functional deficits, daily activities, and social factors.
- Implementing defined treatment guidelines for device fitting.
Main Results:
- Classification of patients' sitting ability simplifies device indication.
- Differentiation between active sitters (able to adjust posture) and passive sitters (requiring support).
- Identification of three distinct groups within both active and passive sitter categories.
Conclusions:
- Examination of sensor and musculoskeletal systems aids in classifying sitting ability.
- A structured classification system facilitates appropriate seating device selection.
- This approach aims to optimize seating solutions for individuals with neuromuscular disorders.
