# Gait Analyzer

Analyze your gait for health disorders at the comfort of your home in your own personal computer.

## Why

Gait abnormalities can be attributed to various [musculoskeletal and neurological conditions](https://stanfordmedicine25.stanford.edu/the25/gait.html) and so gait analysis is being used as an important diagnostic tool by doctors.

Automated gait analysis requires expensive motion capture or multiple-camera systems. But with Gait Analyzer one can analyze their gait in comfort and privacy of their home on their computer.

## How

Gait Analyzer implements the algorithm published in the paper titled [Automated Gait Analysis Based on a Marker-Free Pose Estimation Model](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10384445/).

This algorithm for gait analysis is shown to be as reliable as a motion capture system for most scenarios.

Gait Analyzer further uses Llama2 large language model to interpret the gait data to the end user in simple terms.

## Video Demo

Clicking the above image will open the video on YouTube.

## Features

- Do gait analysis on videos locally on your computer.
- Annotated video with pose-estimation.
- Distances, Peaks and Minima plotted for each leg.
- Displaying Gait data.
- Download of gait data as .csv file.
- Gait pattern explanation using Large Language Model.

## Usage

### Docker

Use Gait Analyzer to analyze your gait on your computer using [Docker](https://hub.docker.com/r/abishekmuthian/gaitanalyzer).

### Setup

Run the LLM model on CPU

```bash
mkdir gaitanalyzer && cd gaitanalyzer
sh -c "$(curl -fsSL https://raw.githubusercontent.com/abishekmuthian/gaitanalyzer/main/install.sh)"
```

Run the LLM model on GPU

_Note: Requires [Nvidia drivers and Container Toolkit](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html#installation) to be installed._

```bash
mkdir gaitanalyzer && cd gaitanalyzer
sh -c "$(curl -fsSL https://raw.githubusercontent.com/abishekmuthian/gaitanalyzer/main/install-gpu.sh)"
```
