Regulation of Stroke Volume01:27

Regulation of Stroke Volume

4.7K
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Motor Units00:46

Motor Units

61.8K
A motor unit consists of two main components: a single efferent motor neuron (i.e., a neuron that carries impulses away from the central nervous system) and all of the muscle fibers it innervates. The motor neuron may innervate multiple muscle fibers, which are single cells, but only one motor neuron innervates a single muscle fiber.

Motor Units

7.5K
The motor unit is a fundamental component of the neuromuscular system and plays a crucial role in coordinating muscle contractions. It consists of a somatic motor neuron, which connects and controls multiple skeletal muscle fibers, forming a single functional segment. The axon of the motor neuron branches out and establishes synaptic connections known as neuromuscular junctions with individual muscle fibers within the motor unit.
Motor units come in different sizes, with smaller units...

Improving Translational Accuracy

14.1K
Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Motor Unit Stimulation

3.6K
When the neuron of a motor unit fires an action potential, it triggers a series of events, leading to a twitch contraction in the muscle fibers. The process of excitation-contraction coupling is crucial in relaying the action potential to the muscle fibers.
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...

    Area of Science:

    • Neurorehabilitation
    • Robotics in Medicine
    • Motor Control

    Background:

    • Proprioceptive deficits are prevalent in stroke survivors, impacting motor recovery and daily function.
    • Augmenting somatosensory feedback to enhance proprioception may improve motor control post-stroke, but evidence remains limited.

    Purpose of the Study:

    • To evaluate the efficacy of robot-aided, somatosensory-focused training on proprioceptive acuity and motor performance in stroke survivors.
    • To assess the feasibility of this novel rehabilitation approach in both sub-acute and chronic stroke populations.

    Main Methods:

    • Twelve stroke survivors underwent two days of robot-aided training using a haptic wrist exoskeleton.
    • Participants performed goal-directed wrist movements with vibro-tactile somatosensory feedback.
    • Proprioceptive acuity and active movement errors were measured pre-intervention, immediately post-intervention, and at a two-day follow-up.

    Main Results:

    • Significant improvements in proprioceptive acuity were observed immediately after training and persisted at the two-day retention test.
    • While motor accuracy showed a positive trend, the improvements were not statistically significant.
    • The robot-aided somatosensory training was found to be feasible for stroke survivors.

    Conclusions:

    • Robot-aided somatosensory rehabilitation effectively enhances proprioceptive acuity in stroke survivors.
    • This training approach demonstrates feasibility and potential for improving motor control and functional outcomes in stroke recovery.
    • Further research is warranted to optimize protocols and confirm motor performance benefits.
