Summary
Hand grip strength, unlike peak expiratory flow, is linked to swallowing difficulties in older adults. This finding suggests hand grip strength may indicate overall muscle health and inform dysphagia interventions.
Area of Science:
- Gerontology
- Clinical Medicine
- Rehabilitation Science
Background:
- Dysphagia is a common condition in the elderly, often associated with reduced muscle strength.
- Assessing swallowing function and its relationship with general physical condition is crucial for elderly care.
Purpose of the Study:
- To investigate the association between swallowing function, hand grip strength, and peak expiratory flow in elderly patients with dysphagia.
- To determine if hand grip strength or peak expiratory flow is a better indicator of swallowing function in this population.
Main Methods:
- 35 elderly patients with dysphagia underwent videoendoscopy (VE) using the Hyodo score for swallowing assessment.
- Hand grip strength and peak expiratory flow tests were conducted on all participants.
- Statistical analysis was performed to evaluate correlations between swallowing function (Hyodo score), hand grip strength, and peak expiratory flow.
Main Results:
- A significant correlation was found between the Hyodo score and both hand grip strength and peak expiratory flow.
- Hand grip strength was also significantly correlated with peak expiratory flow.
- After adjusting for peak expiratory flow, the correlation between the Hyodo score and hand grip strength remained significant, but the correlation between the Hyodo score and peak expiratory flow did not remain significant after adjusting for hand grip strength.
Conclusions:
- Hand grip strength is significantly associated with swallowing function in elderly patients with dysphagia, as measured by the Hyodo score.
- Hand grip strength may serve as a valuable indicator of whole-body muscle strength in this population.
- These findings suggest potential benefits of muscle training interventions for improving dysphagia in the elderly.

The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

01:15Myasthenia Gravis: Diagnostic Tests
1.7K
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.

01:25Deglutition
4.1K
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

2.5K
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...

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

4.0K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.
