The effect of botulinum <scp>toxin‐A</scp> on neural and non‐neural components of wrist hyper‐resistance in adults with stroke or cerebral palsy

BoNT affected the neural component of resistance to passive wrist extension, while leaving the non-neural elastic and viscous components unaffected. This instrumented approach to quantify the effects of BoNT in the wrist and finger flexor muscles on the components of wrist hyper-resistance may have an added value for BoNT treatment evaluation in clinical practice.
