+# EMG Multiple Body Parts Example
+
+This dataset demonstrates recording from multiple body parts with different electrode types:
+- Different electrode types for different body parts
+- Documentation of electrode placement for each type
+- Recording from muscles with different characteristics
+
+## Dataset Structure
+
+The dataset includes a single subject with multiple EMG setups:

+
+## Recording Details
+
+- **Electrode Setup**: Multiple electrode types (surface, fine-wire, needle) on different body parts
+- **Task**: Mechanical perturbation tasks targeting different muscle groups
+- **Electrode Types**: Surface electrodes, fine-wire electrodes, and needle electrodes
+- **Body Parts**: Upper limb, lower limb, and trunk muscles
