Summary
Elderly adults with carpal tunnel syndrome (CTS) show more severe nerve entrapment objectively, despite similar subjective symptoms. Focus on clinical signs and nerve tests, not just patient complaints, for accurate diagnosis in older individuals.
Area of Science:
- Neurology
- Geriatrics
- Clinical Electrophysiology
Background:
- Carpal tunnel syndrome (CTS) is common, but its presentation in elderly adults is not fully understood.
- Previous studies have not clearly defined age-related differences in CTS clinical and electrophysiologic features.
Purpose of the Study:
- To investigate age-related differences in clinical, functional, and electrophysiologic characteristics of carpal tunnel syndrome.
- To compare symptom duration, hand function, autonomic symptoms, thenar weakness, atrophy, and electrophysiologic findings across age groups.
Main Methods:
- Retrospective analysis of 415 consecutive patients referred for suspected CTS over 18 months.
- Categorization of patients into young (<=50), middle-aged (51-64), and elderly (>=65) groups.
- Clinical assessment, functional evaluation, and electrophysiologic testing for CTS diagnosis and severity.
Main Results:
- No significant age differences were found in symptom duration, hand function, or autonomic symptoms.
- Elderly adults exhibited a higher prevalence of thenar weakness and atrophy compared to younger subjects.
- Electrophysiologic abnormalities were more frequent and severe in the elderly group, indicating more significant median nerve entrapment.
Conclusions:
- Older adults with carpal tunnel syndrome present with objective clinical and electrophysiologic evidence of more severe median nerve entrapment.
- Subjective symptom complaints in elderly CTS patients may not accurately reflect disease severity.
- Clinical evaluation of elderly patients with suspected CTS should prioritize objective findings over subjective complaints.
