Lateralization

Lateralization

Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Major Somatic Sensory Pathways

Major Somatic Sensory Pathways

Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the posterior columns...

Cerebral Hemispheres

Cerebral Hemispheres

The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...

Area of Science:

Neuroscience
Biomechanics
Rehabilitation Science

Background:

Stroke frequently results in hemiparesis, affecting gait and muscle function.
Understanding functional differences between left and right hemiparetic gait is crucial for tailored rehabilitation.
Muscle electrical activity and ground reaction forces are key gait parameters.

Purpose of the Study:

To compare electromyography (EMG) and ground reaction force (GRF) parameters during gait.
To investigate differences in gait biomechanics between post-stroke patients with left versus right lower limb involvement.

Main Methods:

Compared 15 post-stroke patients with left hemiparesis to 15 with right hemiparesis (matched for age, gender, weight).
Utilized surface electromyography (EMG) on rectus femoris, tibialis anterior, soleus, and hamstrings.
Measured ground reaction forces (GRF) using a force plate during gait.

Main Results:

No statistically significant differences were found in EMG activity of analyzed muscles (p = 0.6).
No significant differences observed in vertical GRF, stride duration, weight-bearing index, gait velocity, cadence, or stride length (p = 0.53).

Conclusions:

Gait parameters, including EMG and GRF, show no significant differences between left and right hemiparetic stroke patients.
These findings suggest that functional rehabilitation approaches may yield similar outcomes regardless of the affected side in stroke survivors.
