Interventional
Description of intervention(s) / exposure
This study seeks to determine concurrent validity of the CSMi HUMAC (Registered Trademark) Balance device against a ‘gold standard’ force platform measurement (Neurocom EquiTest (Registered Trademark) System).
The 2 different devices will be used to assess balance in 2 populations: 1. a healthy group of community dwelling individuals aged >60 years (N=20); 2. a group of community dwelling individuals aged >60 who have had a stroke (subacute or chronic, ie > 6 weeks post stroke)(N=20).
In a randomized order, subjects will undergo an assessment on each device over the course of about 1 hour. Assessment on the HUMAC device will include a modified Clinical Test of Sensory Interaction on Balance (mCTSIB) and a Limits of Stability (LOS) test. On the NeuroCom device a modified Sensory Organization Test (mSOT) and a LOS test will be performed. The mCTSIB and mSOT each have 4 conditions inwhich a subject stands still and has their balance assessed. The conditions include standing eyes open on a stable surface, standing eyes close on a stable surface, standing eyes open on a compliant surface, and standing eyes closed on a compliant surface. LOS testing requires subjects to stand still and then shift there weight as far as possible in 8 directions (N,NW,W,SW,S etc).
Subjects will be given 3 minute rests between each test condition on either device as well as 5 minute rest when changing between devices.

Diagnosis / Prognosis
Comparator / control treatment
The ability of CSMi Humac (Registered Trademark) Balance device to accurately detect balance impairments will be assessed by comparing the outputs it give to those produced by the Neurocom EquiTest (Registered Trademark) System, which is considered to be the gold standard for assessing balance impairments.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential study candidates who meet inclusion/exclusion criteria will be invited to join the study. Participants will be given practice trials of all balance tasks on both devices to familiarize themselves with the testing procedures, devices and tasks.
After the practice trial, and a five-minute rest, participants will undergo balance assessments on each device in a randomized order. Allocation is not concealed.

Statistical methods / analysis
Assuming 95% sensitivity, 95% specificity, an expected prevalence of stroke at 0.5 and setting a desired precision of 0.01, 39 participants is the minimum sample size required to establish a significant difference of the machines’ effectiveness in discriminating balance performance between healthy older people and older people with stroke.

Summary
Brief summary
Do balance performance measures (both static and dynamic balance) on the low cost HUMAC Balance device have similar classification accuracy for balance impairment as the Neurocom EquiTest (Registered Trademark) System in healthy people over 60 years and people over 60 who have had a stroke
