Chronic transformation of muscle in spasticity: a peripheral contribution to increased tone.
نویسندگان
چکیده
Mechanical properties of relaxed lower leg muscles were assessed by torque measurements during imposed constant velocity dorsiflexion-plantarflexion cycles. At low angular velocities, they exhibited an elastic and an energy-consuming, velocity-independent (plastic) resistance. In most patients with long-standing spasticity, both of these were enhanced. The results support the hypothesis of secondary structural changes of muscles in spasticity.

Spasticity or increase in muscle tone is one of the problems following stroke. Due to this increase in muscle tone, patients are confronted to problems in motor control and difficulties in activities of daily living and complications such as shortness and contracture. The aim of this study is to compare the effects of using splint or botulinum toxin injection on spasticity, range of motion and ...

Background & Aim: Hemiplegia results from upper motor neuron lesion and the patient encounters complications such as spastic paralysis of limbs, weakness and disability in performing movement patterns. One of the effective treatment approaches for these patients is neurodevelopmental treatment(NDT) based on Bobath’s assumptions. On the other hand, the latest researches show that botulinum t...

The development of spinal hyper-reflexia as part of the spasticity syndrome represents one of the major complications associated with chronic spinal traumatic injury (SCI). The primary mechanism leading to progressive appearance of muscle spasticity is multimodal and may include loss of descending inhibitory tone, alteration of segmental interneuron-mediated inhibition and/or increased reflex a...
