ObjectiveTo assess the prevalence of peripheral neuropathy in patients with rheumatoid arthritis (RA) having neuropathic symptoms, and to investigate the relationship between electrophysiological findings of peripheral neuropathy and clinical findings of RA.MethodsPatients with a clinical diagnosis of RA and who had tingling or burning sensation in any extremity were electrophysiologically examined for evidence of peripheral neuropathy. Study parameters, including age, gender, laboratory parameters, duration of RA, and medication, were recorded. The symptoms and signs of neuropathy were quantified with the neuropathy symptom score, and the functional statuses of these patients were assessed.ResultsOut of a total of 30 RA patients, 10 (33%) had peripheral neuropathy: 2 had bilateral carpal tunnel syndrome (CTS), 5 had unilateral CTS, 1 had sensory polyneuropathy, and 2 had motor-sensory polyneuropathy. The mean ages of the patients with and without peripheral neuropathy were 69.4 and 56.5 years, respectively (p<0.05). A significant relationship was found between peripheral neuropathy and anti-cyclic citrullinated peptide (anti-CCP) antibody. However, no relationship was found between peripheral neuropathy and the type of medication, RA duration, the patients' functional status, neuropathic symptoms, erythrocyte sedimentation rate, and C-reactive protein values.ConclusionNeuropathic symptoms are common in RA patients, and it is difficult to distinguish peripheral neuropathy symptoms from those of arthritis. Patients with RA, particularly elderly patients and anti-CCP antibody positive patients who complain of neuropathic symptoms should undergo electrophysiological examination.
[Purpose] To evaluate differences in pectoral muscle tightness according to arm abduction
angle and to determine the best arm abduction angle for stretching of pectoral muscle
tightness in breast cancer patients. [Subjects and Methods] Horizontal abduction
differences of shoulders were measured bilaterally by arm abduction to 45°, 90°, and 135°
to determine the best arm abduction angle for measuring pectoral muscle tightness.
Thirty-two patients were divided into three pectoral muscle stretching groups (A: 45°, B:
90°, and C: 135°). We measured the shoulder range of motion, scores of the Disabilities of
the Arm, Shoulder, and Hand, European Organization for Research and Treatment of Cancer
Quality of Life Questionnaire and the Breast Module, and pain levels (using a visual
analog scale) before and after therapy. [Results] The differences in degree of horizontal
abduction between shoulders were significantly larger for arm abduction to 90° and 135°
than that to 45°. Groups B and C showed greater improvements in horizontal abduction
limitations than group A. [Conclusion] Horizontal abduction differences between shoulders
are prominent when arms are abducted to 90° and 135°. The appropriate arm abduction angle
for measuring horizontal abduction and effective stretching of pectoral muscle tightness
may be >90°.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
