Alterations in Muscle Tone ll01:12

Alterations in Muscle Tone ll

Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...
Skeletal Muscle Relaxants: Therapeutic Uses01:31

Skeletal Muscle Relaxants: Therapeutic Uses

Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx as...

Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin

Directly acting muscle relaxants like dantrolene and botulinum toxin (BoNT) have distinct mechanisms and applications. Dantrolene, a hydantoin derivative, acts on the ryanodine receptor (RYR1) in skeletal muscle cells. RYR1 are calcium channels present at the sarcoplasmic reticulum membrane. In response to excitation, they release calcium ions from the sarcoplasmic reticulum to the cytosol. Calcium promotes actin-myosin-mediated contraction of muscles.
The binding of dantrolene to the RYR1...
Depolarizing Blockers: Pharmocokinetics01:19

Depolarizing Blockers: Pharmocokinetics

Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...

Area of Science:

  • Neurological Surgery
  • Movement Disorders
  • Neurosurgical Technology

Background:

  • Dystonia treatment has evolved over centuries, with historical interventions like myotomy.
  • Lesional neurosurgical procedures targeting the pallidum gained prominence in the 20th century.
  • Deep brain stimulation (DBS) has emerged as a significant advancement in managing dystonia.

Purpose of the Study:

  • To provide a comprehensive overview of deep brain stimulation for dystonia.
  • To discuss critical aspects of DBS, including patient selection and surgical technique.
  • To review the efficacy, outcomes, and potential complications associated with DBS in dystonia patients.

Main Methods:

  • Review of historical and contemporary surgical techniques for dystonia.
  • Focus on bilateral medial pallidal stimulation via deep brain stimulation.
  • Analysis of patient selection criteria, implantation procedures, and clinical effects.
  • Examination of complications and management strategies for DBS in dystonia.

Main Results:

  • Deep brain stimulation, specifically bilateral medial pallidal stimulation, is now a common surgical approach for dystonia.
  • The review highlights key considerations for successful patient selection and technical implementation.
  • DBS demonstrates significant effects on dystonia symptoms, but potential complications require careful management.
  • The applicability of DBS to rarer forms of dystonia is also discussed.
