## What is Lockhart Monitor?

Lockhart Monitor collects as well as processes real-time human locomotion and postural stability information. It can be employed in clinical or laboratory settings in which researchers or health care professionals can assess and monitor the health of patients via gait speed and postural stability measurements. The app serves as a monitoring and diagnostic tool to quantify fall risk as well as balance disorders associated with physiological deterioration.

ABC Scale:
- Interactive Activities-specific Balance Confidence (ABC) scale.
- Measure of confidence in performing various activities without falling or experiencing any form of instability.

Walking:
- Computes gait velocity and time taken to walk a known distance (default is 5 meter walk test). 
- Risk level indicator determines health status and risk for pathology.
- Raw data and results are stored and can be exported for further offline analysis.

Postural Stability:
- Calculates sway area, sway velocity, and path length at run-time. 
- Stabilogram graph reveals movement of center of mass accelerations throughout measurement period. 
- Raw data and results are stored and can be exported for further offline analysis.

Data Storage:
- Walking and postural stability data is saved by date and time as a .csv file.
- Export raw data and results via cloud-based services, email, or directly through iTunes.

## Key features

- Real-time locomotion and postural stability analysis
- Gait velocity and 5-meter walk test
- Postural sway area, velocity, and path length
- Interactive ABC Scale for balance confidence

### 5/5 — Literally cured my cancer

*2023-02-01*

Thanks Lockhart

### 4/5 — Worth trying

*2023-01-27*

The app is free and it does present and record useful data. The data is downloadable as CVS files.  You cannot compare your current score to your previous score on the app itself.  I took screenshots to get around this issue. The norm score does not appear to mean anything. I tested my postural sway standing (almost) completely still and then again swaying as much as I could. Both scores were supposedly close to norm.

### 5/5 — Professor Lockhart is goat

*2023-01-12*

He is goat

### 1/5 — What's the point ???

*2017-02-20*

What is the point of leaving an app that has no active developper, no active website, no instructions, no support and that doesn't work (cannot even keep time in seconds in the walking module) in the appstore ???
Please don't make us loose our time with crap apps !!!

### 5/5 — Brilliant App

*2016-05-07*

A great app to monitor improvements in postural balance. Measure it to manage it.

## Version history (last 3 releases)

### 2.1 — 2018-04-02

This app has been updated by Apple to display the Apple Watch app icon.

- 'Dynamic Stability' module calculates the maximum Lyapunov Exponent for continuous gait.
- Risk scores added to the results of each module along with graphical indicators (these scores will eventually compare with normative values).
- Saving data in 'Postural Stability' module saves all raw signals into one composite .csv file. Previously 'rawAccelerometer', 'rawGyroscope', and   'MotionDevice' saved as separate files.
- Saving data now allows user to input a filename for the dataset.
- Small aesthetic changes to the GUI.

### 2.0 — 2017-06-07

- Tutorial for each module is provided upon first viewing. Instructions can be accessed by the info button in the top left corner of the navigation bar.
- Activities-Specific Balance Confidence (ABC) Scale added as a further fall risk measurement tool.
- Sway area is now calculated by a 95% predictive ellipse.
- Sway path has been added as a measurement value for the 'Postural Stability' module.
- 'Dynamic Stability' module added to collect continuous activity data.

### 1.0 — 2015-08-28

No release notes.
