Postural stability is a more valid measure of stability than

equilibrium stability

Postural Stability Index (PSI), a newly proposed measure of

stability, is a more valid measure of stability than equilibrium

score (ES) traditionally used by researchers, therapists, and

physicians for assessing stability in individuals with balance

problems.

Study participants included 10 people with chronic fatigue syndrome,

10 veterans with medically unexplained symptoms, and 10 healthy

people who completed sensory organization tests to assess their

balance.

Their ankle stiffness, which is generally recognized as an indicator

of balance, was evaluated with PSI and ES. The results suggest that

PSI is a more valid measure of balance than ES.
