AI Article Synopsis
- - The study aimed to determine if women with osteoarthritis (OA) or rheumatoid arthritis (RA) in their hands experience sensory impairments that could affect daily activities.
- - Researchers evaluated sensory function by measuring nerve action potentials and thresholds in the dominant hand of women with OA or RA compared to healthy women.
- - Findings revealed significantly lower sensory nerve action potential amplitudes in the OA and RA groups, suggesting possible axonal loss of sensory fibers, but no notable differences in conduction speed or sensory perception were found.
Article Abstract
Background: Arthritis of the hand can limit a person's ability to perform daily activities. Whether or not sensory deficits contribute to the disability in this population remains unknown. The primary purpose of this study was to determine if women with osteoarthritis (OA) or rheumatoid arthritis (RA) of the hand have sensory impairments.
Methods: Sensory function in the dominant hand of women with hand OA or RA and healthy women was evaluated by measuring sensory nerve action potentials (SNAPs) from the median, ulnar and radial nerves, sensory mapping (SM), and vibratory and current perception thresholds (VPT and CPT, respectively) of the second and fifth digits.
Results: All SNAP amplitudes were significantly lower for the hand OA and hand RA groups compared with the healthy group (p < 0.05). No group differences were found for SNAP conduction velocities, SM, VPT, and CPT.
Discussion: We propose, based on these findings, that women with hand OA or RA may have axonal loss of sensory fibers in the median, ulnar and radial nerves. Less apparent were losses in conduction speed or sensory perception.
