Brief Summary
This study aims to benchmark the performance of an iOS application against the Berg Balance Scale (BBS), which is the most commonly used assessment tool by clinicians for measuring balance across the continuum from acute care to community-based care. An iPhone will be tied around the waist of the participant and concurrent measurements will be taken for five of the fourteen stances which comprise the BBS.

Outcome Measures
Primary Outcomes (1)
Spearman's Rank Coefficient to compare the Root Mean Square from iOS application to the Berg Balance Scale Score
Baseline
Secondary Outcomes (1)
Symmetry Ratio (Root Mean Square Left Leg vs Root Mean Square Right Leg) AP/ML Ratio (Ratio of the Anterior Posterior movement vs the media lateral movement)
Baseline
Interventions
We have designed an iOS application and a belt. The application uses accelerometer data to calculate postural sway. Steps: The phone is kept stable against the lower back of the participant using the belt. The iOS application gives instructions to user to adopt the correct stance (eg: Standing Unsupported, legs side by side) Once the stance is adopted, the application turns on the accelerometer in the phone to sample acceleration along x (media lateral) and z (anterior posterior) axis. These displacements from the mean are used to calculate the Root Mean Square of a person which acts a proxy score for Postural Sway. (Postural sway is defined as the phenomenon of constant displacement and correction of the position of the center of gravity within the base of support)
Eligibility Criteria
