Somatosensation

Somatosensation

The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

Reflex Activity

Reflex Activity

A reflex activity is an automatic, involuntary response to specific stimuli. It is a part of our survival mechanism, designed to protect us from potential harm. For example, when a bright light suddenly shines into our eyes, we instinctively close them or look away. This is a simple reflex activity orchestrated by the nervous system without conscious thought or effort.
A reflex exam is a diagnostic procedure performed by a healthcare professional to evaluate the functionality of a patient's...

Area of Science:

Biomedical Engineering
Rehabilitation Engineering
Human-Computer Interaction

Background:

Mechanically driven haptic feedback systems use hydro-mechanical forces to generate tactile sensations.
Integrating haptic feedback into prosthetics can enhance user experience and functionality.

Purpose of the Study:

To design, fabricate, verify, and validate an integrated mechano-tactile haptic feedback system for a body-powered partial hand prosthesis.
To assess the system's perceptibility and impact on daily task performance in an amputee user.

Main Methods:

Developed a custom haptic feedback mechanism integrated into a Naked Prosthetics device for a patient with finger amputations.
Conducted verification experiments to characterize fingertip-actuator interaction.
Performed a clinical trial with an amputee, evaluating objective (task completion time) and subjective (user feedback) metrics.

Main Results:

Verification experiments characterized the physical interaction of the custom fingertips and feedback actuators.
The integrated haptic feedback system was perceptible to the amputee user.
A moderate improvement in daily task completion time was observed.

Conclusions:

The integration of mechano-tactile haptic feedback into a body-powered partial hand prosthesis is feasible and beneficial.
The system demonstrated practical application and effectiveness in a clinical setting.
Haptic feedback shows potential for improving prosthetic functionality and user experience.
