## 🔬 Overview

The **PhysioMio dataset** provides comprehensive longitudinal and bilateral high-density
surface electromyography (HD-sEMG) recordings from stroke patients with
arm paresis. This unique dataset captures the neuromuscular patterns of both
healthy and impaired forearms during rehabilitation, offering unprecedented
insights into post-stroke motor recovery.

### ✨ Key Features

- 🏥 **48 stroke patients** with arm paresis
- 🤲 **16 distinct hand gestures** recorded per session
- 📅 **Longitudinal recordings** made during patients' stays in rehabilitation clinics
- 🔌 **64-electrode HD-sEMG array** for high-resolution muscle activity
- ⚖️ **Bilateral comparison** between healthy and impaired arms
- 📈 **Recovery progression** tracking across rehabilitation stages

| **Recording Sessions** | 1-2 healthy + 1-12 impaired per patient |
| **Gestures per Session** | 16 hand movements |
| **Electrodes** | 64-channel HD-sEMG array |
| **File Format** | Apache Parquet (.parquet) |
| **Comparison Data** | Healthy arm baseline |

## 🎯 Applications

This dataset is ideal for research in:

- 🧠 **Neuromuscular deficit analysis** in stroke patients
- 🔄 **Motor recovery pattern identification**
- 🤖 **Assistive technology development**
- 📊 **Personalized rehabilitation strategies**
- 🔬 **Comparative healthy vs. impaired arm studies**
- 🎯 **Machine learning for gesture recognition**

The total number of files is 329. The dataset size is 4.4GB.

### 🔍 Data Format

- **File format**: `.parquet` (Apache Parquet)
- **Sampling rate**: 2048 Hz
- **Electrode layout**: 64-channel grid around forearm
- **Session structure**:
  - `healthy_arm/`: 1-2 baseline sessions from unaffected arm
  - `impaired_arm/`: Multiple sessions during rehabilitation
    (typically 1-12 sessions per patient)
  - Each session contains 16 continuous segments, i.e. recordings of a gesture,
    whereas the gesture is indicated in the column `movement_type`. The order
    of gestures is always the same. The first gesture is "Rest".
