Spinal Cord Injury Assistive Technology Rehabilitation

Simple Explanation

This study investigates whether using a mobility assistance dog (ADMob) reduces the effort required from the upper limbs (U/L) when a manual wheelchair user (MWU) with a spinal cord injury (SCI) ascends a ramp. The study compares the mechanical and muscular efforts of the non-dominant U/L with and without the ADMob during ramp ascent. The results suggest that using an ADMob reduces the force and muscle activity needed for ramp ascent, improving mechanical efficiency.

Study Duration

Not specified

Participants

One 26-year-old male with T7 spinal cord injury using a manual wheelchair and mobility assistance dog

Evidence Level

Level 4; Case Report

Key Findings

1
The total and tangential forces applied to the handrim were reduced when using the ADMob, indicating less effort required for propulsion.
2
Net joint movements at the wrist, elbow, and shoulder were decreased with ADMob assistance, suggesting reduced strain on these joints.
3
Muscular demands (biceps, triceps, anterior deltoid, pectoralis major) decreased during uphill propulsion with an ADMob.

Research Summary

This case report examined the impact of using a mobility assistance dog (ADMob) on upper limb (U/L) effort during manual wheelchair ramp ascent in an individual with a spinal cord injury (SCI). The study found that using an ADMob reduced the forces applied to the handrim, decreased net joint movements, and lowered muscular demands in the non-dominant U/L. The conclusion is that ADMob assistance reduces U/L effort and improves efficiency during uphill propulsion for manual wheelchair users with SCI.

Practical Implications

Reduced Upper Limb Strain

Using a mobility assistance dog can potentially reduce the risk of upper limb injuries and fatigue in manual wheelchair users with spinal cord injuries.

Improved Independence

ADMob assistance may facilitate independent performance of wheelchair propulsion in challenging environments, such as ramps.

Consideration of Technological Adaptations

Rehabilitation professionals should carefully assess the potential benefits and drawbacks of ADMob use compared to other technological aids, such as handrim-activated power-assisted wheels.

Study Limitations

1
Single case study limits generalizability.
2
The level of evidence remains low and careful interpretation of the results is required.
3
Surface EMG only allows for monitoring of U/L superficial muscles.
