Details a study which evaluated the subtypes of multiple sclerosis (MS) using quantitative magnetic resonance spectroscopic imaging. Information on the study population; Measurement of metabolite values; Physiological changes in MS.

Patients presenting with isolated partial cervical myelopathy are at high risk for development of multiple sclerosis (MS), especially if lesions suggestive of demyelination are present on cranial magnetic resonance imaging (MRI). This risk is lower, though not precisely known, in patients whose cranial MRI is normal. This clinical issue was addressed by examining the role of paraclinical studies in establishing a diagnosis of MS at the time of initial presentation. Twelve consecutive patients, mean age of 32.2 years, seen over 6.5 years were identified prospectively and included in this study. Numbness was the presenting symptom in 11 of these patients. Symptoms completely resolved in nine patients regardless of treatment with glucocorticoids. Evoked potential (EP) and cerebrosphinal fluid (CSF) examinations assisted in establishing a diagnosis of laboratory-supported definite (LSDMS) or clinically probable (CPMS) MS in six patients at the time of presentation. During a clinical follow-up period of 4.1 years, four developed recurrent neurologic deficits leading to the establishment of a diagnosis of clinically definite MS (CDMS). The presence of a solitary, non-specific lesion on cranial MRI resulted in an increased risk for the development of definite MS. In patients with a clinically isolated cervical partial transverse myelitis (TM) and normal cranial MRI, an accurate diagnosis of MS can usually be made. Revision of the diagnostic criteria for LSDMS is warranted. Multiple Sclerosis (2000) 6, 312–316. [ABSTRACT FROM AUTHOR]

Objective To evaluate whether Constraint-Induced Movement therapy (CI therapy) may benefit chronic upper extremity hemiparesis in progressive multiple sclerosis (MS). Methods Five patients with progressive MS, who had chronic upper extremity hemiparesis and evidence for learned non-use of the paretic limb in the life situation, underwent 30 hours of repetitive task training and shaping for the paretic limb over 2-10 consecutive weeks, along with physical restraint of the less-affected arm and a "transfer package" of behavioral techniques to reinforce treatment adherence. Results The patients showed significantly improved spontaneous, real-world limb use at post-treatment and 4 weeks post-treatment, along with improved fatigue ratings and maximal movement ability displayed in a laboratory motor test. Conclusions The findings suggest for the first time that slowly progressive MS may benefit from CI therapy. Further studies are needed to determine the retention of treatment responses.
