Interpreting the Results
The first screen of the report shows the visit notes that were entered prior to the test. The second screen shows the patient identifier, the date of the test and a summary of the test results, which are described further below.
The third screen of the report shows a plot of the patient’s Eyes-Open and Eyes-Closed phybrata power aligned to their age, against the backdrop of a graph of the average power of healthy individuals across a range of ages. This chart allows the patient and their caregiver to see how the results from the current test relate to the average of healthy people the same age.
Three phybrata measures are derived from the raw sensor data:
- Phybrata Power
- Eyes-Closed/Eyes-Open Phybrata Power Ratio (EC/EO Ratio)
- Left/Right Phybrata Power Ratio (L/R Asymmetry)
The Phybrata Power and L/R Asymmetry are present for both the Eyes-Open and Eyes-Closed tests. Each measure is compared to a normative threshold (0.5 for Eyes-Open, 0.6 for Eyes-Closed), above which the patient’s result is flagged for further assessment. For quick identification, results below the threshold appear in green and results above the threshold appear in red.
The Phybrata Power represents the aggregate power (in Watts) of the movement of the body measured at the head. A higher than threshold Phybrata Power indicates a potential neurological impairment that should be investigated further.
The Left/Right Ratio measures any asymmetry present in the patient’s phybrata measurement. An asymmetry of zero indicates that the patient is centered. An asymmetry less than or above zero indicates that the patient leans preferentially to either the left or right side, respectively. Favoring one side beyond the normative threshold (+/- 0.5) indicates a potential orthopedic impairment that should be investigated further.
- PValues
< -0.5 indicate a lean to the left beyond the normative threshold, indicative of a potential right leg injury.
- Values > 0.5 indicate a lean to the right beyond the normative threshold, indicative of a potential left side injury.
The Eyes-Closed/Eyes-Open Ratio quantifies vestibular performance. An EC/EO Ratio above the normative threshold (2.0) means the Phybrata Power is much higher with the eyes closed, indicating a potential vestibular impairment that should be investigated further.
