Reflex Activity01:08

Reflex Activity

A reflex activity is an automatic, involuntary response to specific stimuli. It is a part of our survival mechanism, designed to protect us from potential harm. For example, when a bright light suddenly shines into our eyes, we instinctively close them or look away. This is a simple reflex activity orchestrated by the nervous system without conscious thought or effort.
A reflex exam is a diagnostic procedure performed by a healthcare professional to evaluate the functionality of a patient's...
Equilibrium and Balance01:15

Equilibrium and Balance

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...
Indirect Motor Pathways01:22

Indirect Motor Pathways

The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...
Somatic Spinal Reflexes01:22

Somatic Spinal Reflexes

Somatic spinal reflexes are rapid, involuntary muscular responses to external stimuli that involve the somatic musculature and the spinal cord.
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...

Area of Science:

  • Biomechanics
  • Robotics
  • Human-Computer Interaction

Background:

  • Human balance deteriorates with age and neurological conditions, increasing fall risks and healthcare costs.
  • Existing assistive technologies focus on muscle power amplification, not direct balance support.
  • Age-related balance decline is a growing societal concern, necessitating novel solutions.

Purpose of the Study:

  • To develop and evaluate an artificial balancer that assists human balance by working with natural posture control mechanisms.
  • To investigate the effectiveness of a flywheel-based system in generating corrective torques.
  • To enhance human balance-keeping capabilities through external torque application.

Main Methods:

  • An artificial balancer utilizing a body-attached flywheel was designed.
  • The device generates corrective torques based on real-time body deflection measurements.
  • Experiments involved participants on a perturbed platform and a balance beam during walking.

Main Results:

  • The artificial balancer effectively supported human balance in experimental settings.
  • The system demonstrated the potential to enhance overall balance-keeping ability.
  • External torque application was shown to be a viable method for balance assistance.

Conclusions:

  • The proposed artificial balancer successfully assists human balance by harmonizing with intrinsic postural control.
  • This technology offers a promising approach to mitigate fall risks associated with age and neurological impairments.
  • Further development could significantly improve mobility and reduce healthcare burdens for individuals with balance deficits.
