Apparent Weight

Apparent Weight

True weight is the measure of the gravitational force acting on an object. However, if the object accelerates, its measured weight is different from its true weight. Similar observations can be made when the object is submerged in water. An object's weight in water is its apparent weight, which is equal to the difference between its true weight and the buoyant forces.
Consider a person standing on a bathroom scale inside an elevator. If the scale is accurate at rest, its reading equals the...

Area of Science:

Rehabilitation Engineering
Biomedical Engineering
Clinical Biomechanics

Background:

Clinical balance assessments often suffer from ceiling and floor effects, limiting their sensitivity.
Technology-based assessments, particularly using virtual reality, offer potential for objective and quantitative balance measures.
The Computer-Assisted Rehabilitation Environment (CAREN) provides a platform for developing advanced balance assessment tools.

Purpose of the Study:

To develop a Performance Assessment Tool (PAT) for the CAREN system.
To evaluate the reliability and validity of the PAT scores.
To compare balance performance between individuals with and without mobility impairments.

Main Methods:

Three virtual reality games were developed and implemented on the CAREN system.
The PAT was tested on 49 participants (36 able-bodied, 13 with impaired mobility).
Measures were transformed into scores to minimize ceiling and floor effects, and validated against clinical balance tests.

Main Results:

The PAT demonstrated an association between scores and age.
Scores showed overlap between high-performing individuals with impairments and low-performing able-bodied individuals.
PAT scores correlated significantly with established clinical balance measures.

Conclusions:

The developed PAT effectively overcomes ceiling and floor effects present in traditional clinical tools.
The PAT provides objective, reliable, and scalable balance assessment.
This tool holds promise for monitoring rehabilitation progress and training effects in individuals with balance impairments.
