Differences in pain perception in women using concentric and monopolar needles.

Objective: To examine pain perception using concentric needle electrodes and monopolar needle electrodes in an all-female study group without underlying hand or arm pain complaints, using study subjects as their own controls.

Design: Prospective randomized study. Two muscles--the biceps and abductor pollicis brevis (APB)--were examined using both a concentric needle electrode and a monopolar needle electrode.

Pilocarpine-induced sweat gland function in individuals with multiple sclerosis.

This investigation tested the hypothesis that cholinergic sweat function of individuals with multiple sclerosis (MS) (MS-Con; n = 10) is diminished relative to matched healthy control subjects (Con; n = 10). In addition, cholinergic sweat function was determined before and after 15 wk of aerobic training in a subgroup of individuals with MS (MS-Ex; n = 7). Cholinergic sweating responses were assessed via pilocarpine iontophoresis on ventral forearm skin.

Physiological measures of therapeutic response to interferon beta-1a treatment in remitting-relapsing MS.

Objective: This pilot study was designed to determine the effects of interferon beta-1a (IFNB) therapy (Avonex) on cortically evoked motor potentials (MEPs) during resting and fatigued states in individuals with multiple sclerosis (MS).

Methods: Eight women with relapsing-remitting MS (mean age 36) and mean Expanded Disability Status Scale (EDSS) score of 3.1 were evaluated before and after 3, 6, and 12 months of IFNB therapy.

Thermal regulatory responses to submaximal cycling following lower-body cooling in humans.

This study compared the effects of pre-exercise cooling with control water immersions on exercise-induced thermal loads derived from steady-state submaximal exercise. Eight healthy male participants [mean (SEM) age 29 (1) years, maximal oxygen uptake 3.81 (0.
