Biomechanical Assessment with Electromyography of Post-Stroke Ankle Plantar Flexor Spasticity
Spasticity has been defined as a motor disorder characterized by a velocity-dependent increase in tonic stretch reflex (muscle tone). Muscle tone consists of mechanical-elastic characteristics, reflex muscle contraction and other elements. The aims of this study were to determine whether to assess spasticity quantitatively, and to characterize biomechanical and electromyographic spasticity asse...
متن کاملBiomechanical measurement of post-stroke spasticity.
BACKGROUND spasticity following stroke is common, but clinical measurement is difficult and inaccurate. The most common measure is the modified Ashworth scale (MAS) which grades resistance to passive movement (RPM), but its validity is unclear. AIM to assess the validity of the MAS. METHODS spasticity was clinically graded using MAS and RPM measured biomechanically in the impaired arm of 11...
متن کاملThe immediate effects of dry needling for ankle and toe plantar flexors on spasticity and balance in patients with stroke
Background: Spasticity is one of the most important symptoms of stroke, which leads to movement constraints and disability. The presence of spasticity in the ankle and toe plantar flexor muscles disturbs the balance and gait of patients with stroke. Dry needling has been introduced as a new method for the treatment of spasticity. The aim of this study was to investigate the immediate effects of...
متن کاملAnkle Plantar-flexor Power in Human Gait
In human gait the majority of mechanical work is generated by the ankle joint. It is commonly thought that concentric contraction of the ankle plantar flexors is the mechanism behind A2 power generation. This study investigated the relationship between the EMG activity of the ankle plantar flexor muscles and A2 power generation. The gait patterns of six healthy adults were recorded. The followi...
متن کاملDynamic spasticity of plantar flexor muscles in cerebral palsy gait.
OBJECTIVE To quantify dynamic spasticity, i.e. the coupling between muscle-tendon stretch velocity and muscle activity during gait, of the gastrocnemius and soleus muscles in children with spastic cerebral palsy. DESIGN Prospective, cross-sectional study. SUBJECTS Seventeen ambulatory children with cerebral palsy with spastic calf muscles, and 11 matched typically developing children. MET...
