Experimental: Electrophysiologic guidance
Electrophysiologic guidance, using electrical stimulation
Device: Electrical stimulation
The purpose of this study is to investigate the use of two ways of locating the muscle for botulinum toxin (BoNT) injection for the treatment of focal hand dystonia and upper limb spasticity located by either electrical stimulation using a needle or ultrasound using sound waves.
Other Name: E-stim
Active Comparator: Ultrasound guidance
Ultrasound guidance,using sound waves through a wand directed towards the targeted muscles.
The purpose of this study is to compare how the muscle is located by either electrical stimulation using a needle or ultrasound using sound waves.
Other Name: Sonography
