|April 1, 1986
Summary
This study provides a systematic method for selecting elastic traction for dynamic splints. Therapists can use simple tools and charts to determine appropriate rubber bands for patient treatment.
Area of Science:
- Orthopedics
- Biomechanical Engineering
- Rehabilitation Therapy
Background:
- Elastic traction is crucial for dynamic splints but often misapplied.
- Limited information exists on systematically selecting elastic traction for upper-extremity splinting.
Observation:
- Material properties of clinical elastic bands were measured using a mechanical testing system.
- Spring constant values ranged from 134 to 531 g, and original lengths from 0.7 to 3.2 inches.
- Elastic bands demonstrated consistent properties and similar durability with repeated use.
Findings:
- A biomechanical analysis identified key factors for proper elastic traction application.
- A simple, logical method was developed to determine elastic traction needs for various diagnoses.
- Goniometers, rulers, and spring scales are sufficient tools for this analysis.
Implications:
- This research educates therapists on the optimal use of elastic traction in dynamic splinting.
- The devised method simplifies the selection process, potentially improving patient outcomes.
- Standardized charts of forces and moments will aid in choosing appropriate rubber bands.
