Item Efficacy of splinting and oral steroids in the treatment of carpal tunnel syndrome: a prospective randomized clinical and electrophysiological study.(2006-09-29) Mishra, Sanjay; Prabhakar, Sudesh; Lal, Vivek; Modi, Manish; Das, Chandi P; Khurana, DheerajOBJECTIVE: To study the efficacy of splinting and oral steroids in the management of carpal tunnel syndrome (CTS). DESIGN: Prospective, randomized, open-label, clinical and electrophysiological study with 3-month follow-up. MATERIALS AND METHODS: Forty patients with CTS were randomly divided into splint group (N-20), wearing splint in neutral position for 4 weeks; and steroid group (N-20), who received oral prednisolone 20 mg/day for 2 weeks followed by 10 mg/day for 2 weeks. Clinical and electrophysiological evaluations were done at baseline and at 1-month and 3-month follow-up. Independent 't' test and paired 't' test were used for statistical analysis. OUTCOME MEASURES: Primary outcome measure was the symptom severity score and functional status score. Secondary outcome measures were median nerve sensory and motor distal latency and conduction velocity. RESULTS: At the end of 3 months, statistically significant improvement was seen in symptom severity score and functional status score in both groups (P<0.001). Median nerve sensory distal latency and conduction velocity also improved significantly in both the groups at 3 months. Improvement in motor distal latency was significant (P=0.001) at 3 months in steroid group, while insignificant improvement (P=0.139) was observed in splint group. On comparing the clinical and electrophysiological improvement between the two groups, except for the functional status score, there was no significant difference at 3-month follow-up. Improvement in functional status score was significantly more in steroid group (P=0.03). CONCLUSION: There was significant improvement in both groups, clinically as well as electrophysiologically, at 3 months. On comparing the efficacy of the two treatment methods, except for the functional status score, there was no significant difference between the two groups.Item Posterior circulation stroke in a cannabis abuser.(2009-01-24) Bal, Simerpreet; Khurana, Dheeraj; Lal, Vivek; Prabhakar, SudeshItem Transcranial magnetic stimulation: role in the evaluation of disability in multiple sclerosis.(2005-06-13) Sahota, Preeti; Prabhakar, Sudesh; Lal, Vivek; Khurana, Dheeraj; Das, Chandi P; Singh, ParampreetBACKGROUND: In patients with multiple sclerosis (MS), transcranial magnetic stimulation (TMS) has shown significant prolongation of central motor conduction time (CMCT). Abnormal CMCT may reflect sub-clinical involvement of motor pathways and correlate with clinical motor disability. OBJECTIVE: To determine the diagnostic yield of TMS in MS and the possible correlation of TMS abnormalities with clinical disability. MATERIALS AND METHODS: Thirty patients with clinically definite MS presenting in acute relapse or with progressive disease course and 30 healthy controls were evaluated. TMS parameters evaluated included threshold intensity, motor evoked potentials (MEP) amplitudes and latencies and CMCT. Reassessment studies were done after three months. STATISTICAL ANALYSIS: Student t-test, Mann-Whitney U test and Spearman's rank correlation test were used to assess the relationships. RESULTS: Patients with MS had significantly higher threshold intensities, prolonged CMCT and reduced MEP amplitudes as compared to controls. Abnormalities in at least one parameter were observed in 86.7% of patients. When inter-side asymmetries in MEP latency and/or in CMCT were considered, the diagnostic yield increased to 96.7%. The diagnostic yield was 74.7% for visual evoked potentials, 13.3% for brainstem auditory evoked response and 10% for cerebrospinal fluid oligoclonal band. One MS patient without pyramidal or cerebellar dysfunction had prolonged CMCT. CMCT abnormalities correlated significantly with the degree of pyramidal signs, limb ataxia, intention tremor, dysdiadokokinesia and overall cerebellar score. In patients who had clinical improvement, follow-up studies showed improvement in CMCT parameters. CONCLUSION: TMS is a highly sensitive technique to evaluate cortico-spinal conduction abnormalities in MS that may have no clinical correlate and in monitoring the course of the disease. The effects of cerebellar dysfunction on TMS results need further evaluation.
