“…We can see that a diverse range of studies/systems have been conducted/built. Some are for the upper extremity including those for arms [10,12,13,16,17,20,21,23,25,27,30,[37][38][39], hands/fingers [10, 11, 14, 17, 20, 23, 25-28, 30-33, 38], and shoulders [10-14, 16, 20-23, 27, 29, 30, 35, 38, 39], while the others are on the lower extremity including those for ankles [18,19,36], gait [15,19,24,36], balance [15,19,23,24,36], and postural [19,23,24]. However, most of these studies are conducted in laboratory setting and thus are less feasible in real clinical scenarios [1] .…”
