Fig. 1From: Quantitative evaluation for spasticity of calf muscle after botulinum toxin injection in patients with cerebral palsy: a pilot studyRationales of spasticity measurement for modified Tardieu scale (MTS) and our quantitative modified Tardieu approach (QMTA). a Conventional MTS approach. b Our QMTA approach. c Expected curves of resistance during a manual stretch. d Expected curves of displacement during slow or fast stretches. Both curves of (c) and (d) are derived from a fast stretch on a spastic ankle joint of a patient with cerebral palsyBack to article page
