Pressure data is in kPa, by hand region, and for each subject. Values were obtained by the peak pressure at each cut (three cuts) for each pruning model (A, B, and C). The data was collected with Tekscan Grip Versatek Wireless System at 50Hz. The sensors were attached to a thin textile glove (helanca glove). Since it is an unimanual task, only the right-hand data is available. Only male, adults (18 to 29 years old), right-handed and able-bodied subjects performed the activities. No one reported MSDs symptoms up to 12 months prior the experiment.


Steps to reproduce

Draw marks at every 20mm from the extremity of the wooden skewers (pinus wood - 180x3mm). A support with adjustable height must be used, so the subject will maintain a neutral shoulder and wrist position. Measure the distance from the floor to the elbow for each subject and add 150mm to it. Adjust the height of the support for each subject. Make a demonstration on how to position itself in front of the structure and cut the skewers. Let the subject perform the cuts at his time (no pause between the three cuts though). At the end of the three cuts (one skewer), the subject has to answer the discomfort and perceived effort questionnaires. The sequence of use for the pruning shears was randomized. More details are in the thesis linked to this dataset (in Portuguese).
