A motor cortex excitability and gait analysis on Parkinsonian patients.

Transcranial magnetic stimulation (TMS) parameters were recorded in a lower limb muscle and correlated with the gait parameters of 25 patients with Parkinson's disease (PD) with and without dopamine substitution treatment (DST) and 10 control subjects. Single and paired-pulse TMS were recorded in the tibialis anterior muscle (TA). Gait analysis was performed using a 3D motion analysis system.

Effect of ascorbic acid in patients with Charcot-Marie-Tooth disease type 1A: a multicentre, randomised, double-blind, placebo-controlled trial.

Background: Charcot-Marie-Tooth disease type 1A (CMT1A) is a hereditary peripheral neuropathy that affects roughly one in 5000 births. No specific therapy currently exists for this degenerative disorder, which is characterised by distal progressive muscle atrophy and sensory loss, although ascorbic acid has been shown to reduce demyelination and improve muscle function in a transgenic mouse model of CMT1A. We tested the safety and efficacy of ascorbic acid in adults with CMT1A.
