Candidates for Synergies: Linear Discriminants versus Principal Components

Figure 2

Six kinematic synergies obtained for subject 2 using PCA (red) and ULDA (green). Each synergy is about 0.45 s (39 samples) in duration (data acquired at 86 Hz). T: thumb; I: index finger; M: middle finger; R: ring finger; P: pinky finger; MCP: metacarpophalangeal joint; IP: interphalangeal joint; PIP: proximal IP joint.
