* p < 0.001; ** p < 0.05; – parameter was not reported. The MAE results from [26] are calculated in this work to obtain a mean value of the individual results (note: the recordings of the occasional and frequent motion categories [26] were performed by the same subject). Refer to “PRV and statistical analysis” section for parameter definitions. Refer to Table 1 for the conditions of the study
