Post Stroke Spasticity vs Movement Disorder - Diagnosis and Management-Post Stroke Spasticity vs Movement Disorder

Video Transcription

Video Summary

The video discussed post-stroke movement disorders, specifically focusing on spasticity and dystonia. The upper motor neuron syndrome associated with stroke can manifest as spasticity and dystonia, with weakness underlying these symptoms. Spasticity is characterized by velocity-dependent increased resistance to passive stretch, while dystonia involves sustained muscle contractions and repetitive twisting movements. The pathophysiology of spasticity involves disinhibition effects and exaggerated stretch reflexes due to damage in the corticoreticulospinal tract. Dystonia, on the other hand, is a sensory motor modulation issue. Treatment options for both spasticity and dystonia include therapy, oral medications, neurotoxin injections, intrathecal baclofen pumps, and deep brain stimulation. The discussion also included two patient cases. In the first case, a patient with post-stroke dystonia and spasticity received botulinum toxin injections and e-stem therapy, which resulted in improved sensory function and arm control. In the second case, a patient with traumatic brain injury and cervical dystonia tried e-stem therapy, which led to improvements in head posture and awareness. The video also mentioned the network model of dystonia, which suggests that altered sensory motor processing and impaired sensory function contribute to dystonic movements. E-stem therapy may restore the sensory motor connection and modulate motor output to treat dystonia. The video concluded by highlighting the need for further research on the optimal dose and effectiveness of e-stem therapy for dystonia.
