1. A functional electrical stimulation (FES) system comprising:
an FES device configured to be worn on an associated body part and including electrodes arranged to apply electrode energization patterns to the associated body part to move the associated body part by functional electrical stimulation; and
a camera arranged to acquire video of the associated body part;
an electronic processor programmed to perform a calibration method to calibrate the FES device to move the associated body part to one or more target positions, the calibration method including:
applying a candidate electrode energization pattern to the associated body part using the FES device, and
determining the position of the associated body part produced by the application of the candidate electrode energization pattern using the FES device by analyzing the acquired video.
