Botulinum toxin A is considered an effective treatment for involuntary facial movements. We examined whether treatment efficacy maintained or changed over time with two products, Botox and Dysport, in patients with hemifacial spasm, facial synkinesis and benign essential blepharospasm.We retrospectively investigated 87 consecutive patients (51 women, 36 men) who had undergone treatment for ≥6 years.

Objective: To study the effects of closed-loop auditory feedback cues, corresponding to patient self-motion, on the walking abilities of patients with Parkinson's disease, in comparison to the effects of open-loop (metronome-like) auditory cues.

Methods: Sixteen patients on their regular medication schedule participated. A device which translates patient steps into a clicking cue sounded by earphones provides auditory feedback for gait pattern correction.

Background: Our aim was to study the effects of visual feedback cues, responding dynamically to patient's self-motion and provided through a portable see-through virtual reality apparatus, on the walking abilities of patients with Parkinson's disease.

Methods: Twenty patients participated. On-line and residual effects on walking speed and stride length were measured.

Background: Long-term therapy with botulinum toxin is sometimes associated with therapy failure following repeated injections of the neurotoxin, presumably due to specific antibody production. Primary therapy failure with botulinum toxin is less common and poorly understood.

Objectives: To examine the effectiveness of the botulinum neurotoxin Dysport in patients with blepharospasm and hemifacial spasm after primary or secondary failure with Botox treatments.
