Skeletal Muscle Relaxants: Therapeutic Uses01:31

Skeletal Muscle Relaxants: Therapeutic Uses

445
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...

Myasthenia Gravis: Diagnostic Tests

581
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
The edrophonium test is a diagnostic tool for myasthenia gravis. It involves...

Classification of Skeletal Muscle Relaxants

2.3K
Skeletal muscle relaxants are a group of drugs that can reduce muscle stiffness and induce temporary paralysis to relieve pain. These agents can act centrally to reduce muscle tone or spasms in painful conditions such as multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), or spinal injuries; they are called antispasmodics or spasmolytics.
Peripherally acting skeletal muscle relaxants interfere with the neurotransmission at the neuromuscular end plate to induce paralysis during...

Myasthenia Gravis: Overview and Treatment

1.0K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Area of Science:

  • Oncology
  • Rehabilitation Medicine
  • Physical Therapy

Background:

  • Spinal accessory nerve injury can lead to debilitating shoulder and neck dysfunctions, significantly impacting patients' quality of life.
  • Head and neck cancer patients often experience these dysfunctions due to treatment or the disease itself.

Purpose of the Study:

  • To evaluate the efficacy of manual therapy combined with standard physiotherapy for improving muscle mechanical properties, neck and shoulder function, pain, and quality of life in head and neck cancer patients.
  • To compare the outcomes of combined manual therapy and physiotherapy with standard physiotherapy alone.

Main Methods:

  • A prospective, randomized, controlled, double-blind clinical trial was conducted.
  • 26 participants were randomized into two groups: a control group receiving standard physiotherapy and an intervention group receiving manual therapy plus standard physiotherapy.
  • Outcome measures included muscle mechanical properties, active range of motion, shoulder pain and disability, and quality of life.

Main Results:

  • The intervention group showed a significant reduction in upper trapezius and sternocleidomastoid muscle stiffness compared to the control group (P=.001).
  • Both groups experienced improvements in neck and shoulder active range of motion, shoulder pain, and quality of life (P<.01).
  • Muscle thickness decreased bilaterally in both groups (P<.01).

Conclusions:

  • Manual therapy, when added to standard physiotherapy, demonstrates superior effectiveness in enhancing neck and shoulder function and improving quality of life.
  • The combined approach significantly reduces muscle stiffness, offering a more comprehensive treatment strategy.
  • Clinicians are advised to integrate manual therapy into treatment protocols for head and neck cancer patients to optimize functional recovery and well-being.
