Help for SwayStar™ (4.7.3.265)
Age at test: 49
Key Signs:
Typically these patients show results inconsistent with a balance disorder. For example, pitch sway velocity for two-legged stance eyes closed on foam is half that for eyes closed on a firm surface (see summary below). Here even for two-legged stance eyes open on a firm surface (see traces below) slow sway movements were observed. Such sway is almost never seen for patients with real balance problems. The patient cannot stand on 1 leg, eyes open, for more than 7 seconds, but again, inconsistently, this patient can perform the task walking with eyes closed and tandem steps with normal times.
Standing on two legs, eyes open, firm surface.
Summary Data:
Pitch velocity sway values for stance on foam are less than on a firm surface, leading to a negative somatosensory component in the Sensory Analysis Graph. Sway for stance eyes closed is excessively greater than with eyes open leading to an apparently greater than normal use of visual inputs in the Sensory Analysis Graph. Roll velocity were as large eyes closed on foam as on firm support surface.
Standing on one leg without loss of balance was not possible but tandem walking could be performed within a normal time. However pitch was greater than roll velocity.
Stairs and barriers tasks were performed slowly.
Indexes:
Greater than normal.
