Abstract
Introduction/aims: The single simple question (SSQ), "What percentage of normal (0%-100%) do you feel regarding your disease?" has proven feasible and valid in assessing myasthenia gravis and a heterogeneous spectrum of neuropathies. This study explores the utility of the SSQ in axonal polyneuropathies (PNPs), encompassing diabetic neuropathy, and evaluates its responsiveness to scale changes.
Methods: A retrospective chart review of 150 patients with axonal PNP responding to the SSQ was performed. Patients underwent clinical and electrophysiological evaluations, and were evaluated by clinical and disability scales, including the Medical Research Council sum score, modified Toronto Clinical Neuropathy score (mTCNS), Overall Neuropathy Limitation Scale, and Rasch-built Overall Disability Scale (RODS).
Results: The SSQ total scores correlated moderately with both the RODS score (r = .59, p < .001) and the mTCNS symptom score (r = -.43, p < .001), maintaining significance after adjustment for multiple comparisons. Longitudinally, after adjusting for multiple comparisons, the change in mTCNS symptom score retained statistical significance (adjusted p = .048). The SSQ did not show any association with electrophysiological parameters or sensory symptoms, other than a lower score in those with pain (100% with SSQ <40%, 85% with SSQ 40%-70%, and 34% with SSQ >70%).
Discussion: The SSQ is a feasible, valid scale that may be utilized to assess and follow patients with length-dependent axonal PNPs. Given that the SSQ is not strongly associated with clinical and disability scales or electrophysiological findings, additional investigations are required for a comprehensive assessment of PNP.
期刊介绍:
Muscle & Nerve is an international and interdisciplinary publication of original contributions, in both health and disease, concerning studies of the muscle, the neuromuscular junction, the peripheral motor, sensory and autonomic neurons, and the central nervous system where the behavior of the peripheral nervous system is clarified. Appearing monthly, Muscle & Nerve publishes clinical studies and clinically relevant research reports in the fields of anatomy, biochemistry, cell biology, electrophysiology and electrodiagnosis, epidemiology, genetics, immunology, pathology, pharmacology, physiology, toxicology, and virology. The Journal welcomes articles and reports on basic clinical electrophysiology and electrodiagnosis. We expedite some papers dealing with timely topics to keep up with the fast-moving pace of science, based on the referees'' recommendation.
