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...
Exercise Stress Test01:26

Exercise Stress Test

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes
Muscle Stimulation Frequency01:22

Muscle Stimulation Frequency

The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.
Wave summation
At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...
Equipments Used To Measure Blood Pressure01:30

Equipments Used To Measure Blood Pressure

Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
Cellular Adaptation II: Hypertrophy01:26

Cellular Adaptation II: Hypertrophy

Hypertrophy is the increase in the size of individual cells, resulting in the enlargement of a tissue or organ. Unlike hyperplasia, which involves an increase in cell number, hypertrophy is characterized by an increase in cell volume. This process often occurs in response to higher functional demand or hormonal stimulation, leading to the production of more structural proteins and organelles, thereby enhancing the cells' work capacity.There are two primary types of hypertrophy: physiological...
Energy Balance01:19

Energy Balance

The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...

Area of Science:

  • Biomedical Engineering
  • Rehabilitation Technology
  • Human Movement Science

Background:

  • Existing vibrotactile sensory augmentation technologies are impractical for home use due to size, cost, and complexity.
  • Need for accessible, portable solutions for balance rehabilitation.

Purpose of the Study:

  • To design and develop a cell phone-based vibrotactile feedback system for balance rehabilitation.
  • To evaluate the system's effectiveness in reducing body sway.

Main Methods:

  • Developed an iPhone-based system with accelerometers and custom software for tilt estimation.
  • Utilized a 'tactor bud' accessory for vibrotactile feedback.
  • Tested with healthy subjects and subjects with vestibular deficits during various balance stances.

Main Results:

  • The system provided real-time vibrotactile cues, informing corrective postural responses.
  • Both healthy and vestibular-deficit groups significantly reduced body sway (RMS, elliptical area).
  • Participants spent more time within the no-feedback zone and showed increased sway frequency.

Conclusions:

  • Real-time vibrotactile feedback effectively reduces body sway.
  • The system's advantages (cost, size, accessibility) make it suitable for home-based balance training evaluation.
