Figure 1From: Evaluation of EMG, force and joystick as control interfaces for active arm supportsExperimental setup. Top) Picture of the experimental setup. Bottom) Schematic diagram of the experimental setup. The forearm of the participants was securely strapped to a rigid structure using a padded brace around the styloid processes. The EMG electrodes were placed at the biceps and triceps muscles. The resulting forces from the biceps and triceps activation where measured with a 1DOF force sensor located at the wrist. The joystick was located in front of the subject.Back to article page
