Spasticity and spastic dystonia: the two faces of velocity-dependent hypertonia.
BACKGROUND Spasticity and spastic dystonia are two separate phenomena of the upper motor neuron syndrome. Spasticity is clinically defined by velocity-dependent hypertonia and tendon jerk hyperreflexia due to the hyper-excitability of the stretch reflex. Spastic dystonia is the inability to relax a muscle leading to a spontaneous tonic contraction. Both spasticity and spastic dystonia are prese...
متن کاملThe effect of cannabinoids on the stretch reflex in multiple sclerosis spasticity.
The aim of this observational study was to assess the efficacy of a tetrahydrocannabinol-cannabidiol (THC : CBD) oromucosal spray on spasticity using the stretch reflex in patients with multiple sclerosis (MS). Numeric rating scale (NRS) for spasticity, modified Ashworth scale (MAS), and the stretch reflex were assessed before and during treatment in 57 MS patients with spasticity eligible for ...
متن کاملThe quadriceps stretch reflex in human spasticity.
The similarity of decerebrate rigidity in the cat and human spasticity has been noted frequently since the initial observation of Sherrington (1897). Walshe (1919, 1929) considered the two conditions to be physiologically identical, although spasticity 'is but a fractional expression of decerebrate rigidity'. More recently Brodal (1962) and Rushworth (1964) have referred to this similarity. Bro...
متن کاملInfluence of posture and muscle length on stretch reflex activity in poststroke patients with spasticity.
OBJECTIVE To investigate the influence of different positions on stretch reflex activity of knee flexors and extensors measured by electromyography in poststroke patients with spasticity and its expression in the Ashworth Scale. DESIGN Crossover trial with randomized order of positioning. SETTING Outpatient rehabilitation center in the Netherlands. PARTICIPANTS Poststroke patients (N = 19...
متن کاملPsychological Changes in Patients With Multiple Sclerosis
Introduction: Multiple Sclerosis (MS) as a stressful event, despite causing negative psychological changes, may lead to positive ones as well. Objective: This study was mainly conducted to examine the implications of posttraumatic growth and demoralization and also to determine the relationship between them in patients with MS. Materials and Methods: This was a cross-sectional study, in which...
