Associated movements in hemiplegic limbs during yawning
Associated movements in hemiplegic limbs during yawning were observed in most stroke patients, particularly in males and those with left-sided hemiplegia or hypotonia. These findings suggest a link to ancestral functions and potential rehabilitation applications.
Area of Science:
- Neurology
- Neuroscience
- Rehabilitation Medicine
Background:
- Yawning is an ancient, stereotyped behavior.
- Associated movements during yawning are common in neurological conditions.
Purpose of the Study:
- To describe associated movements in hemiplegic limbs during yawning.
- To investigate relationships with gender, hemiplegia laterality, and muscle tone.
Main Methods:
- Observational study of 75 patients with anterior circulation stroke.
- Exclusion of patients with arthropathy, autoimmune diseases, muscular disorders, or injuries.
Main Results:
- 78.6% of hemiplegic patients exhibited associated movements during yawning.
- Movements were more frequent in males (83%), left-sided hemiplegia (94%), hypotonia (87%), upper limbs (91%), and proximal joints (72%).
- Yawning onset was around 36-38 hours post-stroke.
Conclusions:
- Associated movements in hemiplegic limbs may reflect the re-emergence of ancestral functions.
- Further research is needed to understand variations and clinical applications in rehabilitation.

Muscles that Move the Head
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
