“…Devices were attached to 11 different anatomical sites on the body (Table 4 ), of which the wrist was the most common site (43.2%; n = 16) [ 37 – 39 , 41 , 43 , 49 – 51 , 54 , 56 – 58 , 61 , 69 – 71 ], followed by the waist or lower back (27.1%; n = 10) [ 36 , 38 – 40 , 46 , 55 , 56 , 58 , 61 , 67 ]. With regards to the method of attachment, eight different methods were used (Table 4 ) of which straps (45.9%; n = 17) [ 35 – 41 , 43 , 46 , 47 , 49 , 54 , 57 – 61 , 70 ] and clips were the most commonly used (16.2%; n = 6) [ 45 , 52 , 56 , 62 , 64 , 65 ]. Nine studies failed to report how the wearable was attached to the body (24.3%) [ 42 , 45 , 48 , 50 , 51 , 55 , 63 , 68 , 69 ], while four failed to report where they were attached (10.8%) [ 42 , 63 , 65 , 68 ].…”
