Robot-assisted task-oriented upper extremity skill training in cervical spinal cord injury: a feasibility study

Area of Science:

• Robotics in Rehabilitation
• Neurorehabilitation
• Spinal Cord Injury Research

Background:

• Cervical spinal cord injury (C-SCI) significantly impacts arm-hand function (AHF) and skill performance (AHSP).
• Haptic robot technology offers a potential avenue for targeted motor rehabilitation.

Observation:

• A prospective multiple case study involving five C-SCI patients was conducted over 6 weeks.
• Feasibility, motivation, and expectations regarding haptic robot (Haptic Master - HM) use were assessed using validated questionnaires (USE, IMI, CEQ).
• Functional outcomes were measured using standardized tests for AHF and overall function.

Findings:

• The Haptic Master (HM) demonstrated feasibility for C-SCI rehabilitation, with positive therapist feedback on usability.
• Participants reported motivation to train with the HM, rating its credibility higher than their expectations for improvement.
• Limited progress was observed in International Classification of Functioning, Disability and Health (ICF) function and activity levels among the participants.

Implications:

• Haptic robot technology is a feasible tool for C-SCI rehabilitation, though its usability can be enhanced.
• Further research is required to identify optimal C-SCI patient groups and rehabilitation stages for HM intervention.
• This study highlights the need for tailored approaches to maximize the benefits of robotic assistance in spinal cord injury recovery.
