Description

The dataset presented in the article comprises of finger forces of participants during a finger pressing task. The finger pressing task involves the production of fingertip forces using Index, Middle, Ring, and Little (I, M, R&L) fingers of the right hand. During experimentation, first, the participants performed the Maximum Voluntary Contraction (MVC) task, where they were instructed to produce maximum possible force from each finger individually and all together. The MVC task is followed by the finger pressing task that involves two conditions, i.e., without the epilogue and with the epilogue. The epilogue is a particular case of post-trial visual feedback where only the outcome of the just-concluded trial is shown to the participant. The force levels in the experiments of both these cases were normalized with respect to MVC. Fourteen healthy participants were recruited for the experiments and were instructed to produce fingertip forces using four fingers of the right hand with the target line at 15% MVC (15% of the force that they produced in the MVC task). Each of the two conditions has 30 trials, and the subjects performed 60 trials in total for the complete experiment apart from the MVC task. A single trial of both the conditions lasted for sixteen seconds, where for the initial eight seconds, there is visual feedback followed by the visual occlusion period where there is no visual feedback. For the experiment involving epilogue the participants were shown the feedback of the just-concluded trial, whereas for the without epilogue case, they were not given any post-trial feedback. The dataset consists of three files; the first file has the data of Maximum Voluntary Contraction (MVC) data, the second file has the data of without epilogue case, and the third file has the data of with epilogue case.
