Electromyography (EMG) data set of 4 gestures performed with the right hand.

The design and implementation of an anthropomorphic robotic hand control system for the Bioengineering and Neuroimaging Laboratory LNB of the ESPOL were elaborated. The myoelectric signals were obtained using a bioelectric data acquisition board (CYTON BOARD) using six channels out of 8 available, which had an amplitude of 200 [uV] at a sampling frequency of 250 [Hz]. 

The data were obtained through an experiment that consisted of the subject mimicking four right-hand gestures with 20 repetitions per gesture (80 repetitions in total) in each session; each movement was captured at a 2-second interval. For this purpose, ten healthy subjects were recruited, of whom five were female and whose average age was 30 years. All subjects were right-handed (score 64.88) measured by the Edinburgh Handedness Inventory (EHI) dexterity test (Oldfield RC, 1971). All individuals signed the informed consent. The experiment consisted of 13 electrodes, the distribution of which can be seen in Illustration 1 and Table 1. The forearm was prepared during the procedure, and the electrodes were fixed with adhesive tape to improve skin contact.
