A Grasp Taxonomy for People with C5-7 Spinal Cord Injury.
Summary
Researchers developed a new grasp taxonomy for individuals with spinal cord injury (SCI). This tool characterizes dexterous abilities, aiding in the design of assistive technologies for SCI manual function.
Area of Science:
- Rehabilitation Medicine
- Biomedical Engineering
- Human Movement Science
Background:
- Grasp taxonomies are crucial for assessing manual abilities but are lacking for individuals with spinal cord injury (SCI).
- This absence creates challenges in evaluating assistive devices for dexterous manipulation in SCI populations.
- Existing assessments often overlook specific dexterous abilities relevant to SCI users.
Purpose of the Study:
- To develop a preliminary grasp taxonomy for individuals with C5-7 spinal cord injury (SCI).
- To characterize the unique grasping strategies employed by individuals with SCI.
- To inform the design and assessment of assistive technologies for SCI.
Main Methods:
- Analysis of six publicly available videos depicting grasp strategies in individuals with C5-7 SCI.
- Development of a preliminary grasp taxonomy based on observed strategies.
- Validation of the taxonomy's completeness through an egocentric video case study of an individual with C5-6 SCI.
Main Results:
- A taxonomy of 27 grasping strategies was developed.
- Fourteen of these grasping strategies are novel and unique to this study.
- The egocentric case study indicated the taxonomy captures key grasp strategies relevant to the SCI population.
Conclusions:
- The developed grasp taxonomy provides a novel characterization of dexterous abilities in individuals with SCI.
- This taxonomy can address gaps in current technology design and assessment for SCI.
- The proposed taxonomy should guide the development of innovative grasp assistance technologies for SCI.

01:16Spinal Cord: Cross-sectional Anatomy
1.6K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

01:54The Spinal Cord
29.1K
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.

2.5K
The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...

01:23Spinal Nerves: Anatomy
1.8K
Spinal nerves are pivotal conduits in the nervous system, bridging the central nervous system (CNS) with the peripheral nervous system (PNS). These nerves enable a complex communication network between the brain, spinal cord, and the rest of the body, facilitating sensory input, motor output, and autonomic functions.

01:10Spinal Cord: Information Processing
1.1K
The spinal cord is an integral hub for motor and sensory information that enables the brain to communicate with the peripheral nervous system (PNS). This communication consists of relaying sensory data and transmission of motor commands.
Sensory Information Processing
Sensory information processing begins at the sensory receptors located in the skin and other tissues, which detect somatic sensory stimuli such as touch, temperature, or pain. These receptors function as catalysts, initiating...
