Influencing lumbar posture through real-time biofeedback and its effects on the kinematics and kinetics of a repetitive lifting task

Evidence for the Effectiveness of Feedback from Wearable Inertial Sensors during Work-Related Activities: A Scoping Review

“…No included study reported post-intervention monitoring to assess the retention of improvements following WIST feedback. Four types of feedback prompts were identified throughout the included studies: auditory [ 68 , 71 , 73 , 74 , 75 , 80 ]; vibrotactile (haptic) [ 69 , 72 , 74 , 76 , 77 , 78 , 79 ]; visual [ 67 , 70 , 71 , 72 , 74 , 75 , 78 ] and summary feedback (visual) [ 74 ]. The most common multimodal feedback interaction was auditory and visual [ 71 , 74 , 75 ].…”

“…The most common multimodal feedback interaction was auditory and visual [ 71 , 74 , 75 ]. Most studies applied concurrent bandwidth feedback [ 67 , 69 , 73 , 75 , 76 , 77 , 79 , 80 ] (i.e., a feedback prompt when a movement variable exceeds a pre-determined set-point (feedback trigger) during the activity/task [ 131 , 132 ]; and in conjunction with a pre-determined time period [ 68 , 71 , 72 , 74 , 78 ] ( Table 4 ); the remaining studies used terminal bandwidth feedback (feedback post-activity) [ 70 ] and summary feedback in addition to visual, auditory and vibrotactile feedback [ 74 ].…”

“…Improved trunk posture occurred using various types of WIST feedback for different tasks, for example, auditory during lifting [ 73 ], moving patients from bed to chair [ 80 ] and office tasks [ 68 ], vibratory/auditory during nursing tasks [ 74 ], visual/vibrotactile during several simulated workplace tasks [ 78 ] vibrotactile during a computer task [ 76 ] and vibrotactile [ 69 ] and visual [ 70 ] during dental procedures ( Table 3 ). However, using vibratory feedback alone during sedentary tasks resulted in no trunk posture improvements [ 77 ].…”

“…The sensor attachment methods in the fourteen included studies were diverse: ‘on’ clothing ( n = 6) [ 68 , 69 , 70 , 78 , 79 , 80 ]; within a smart sensing garment ( n = 1) [ 74 ]; worn as a belt ( n = 1) [ 67 ]; direct skin attachment using tape ( n = 2) [ 73 , 76 ]; magnetic clasp to undershirt ( n = 1) [ 77 ]; secured by bands on ears positioned posteriorly on neck [ 72 ]; and not reported ( n = 2) [ 71 , 75 ] ( Table 5 ). Ribeiro, Sole [ 68 ] evaluated workers’ perception of WIST usefulness using a Likert scale.…”

A Perspective on Implementing Movement Sonification to Influence Movement (and Eventually Cognitive) Creativity

“…It consists of mapping a movement parameter into sound, and depending on how the specified movement parameter (s) change (s) a sound is triggered or changes characteristics, e.g., frequency and amplitude (Effenberg, 2005;Hermann et al, 2011;Dyer et al, 2017). For example, a sound tone is triggered when a joint angle exceeds a certain threshold (e.g., Boocock et al, 2019) or a music melody is progressively distorted in reference to the amplitude of a joint angle increase (e.g., Lorenzoni et al, 2019). Given the inherent tight link between movement and sound (Stanton and Spence, 2020), movement sonification has recently gained an increased interest in the motor learning and control field as a suitable strategy to deliver augmented feedback (Sigrist et al, 2013;Dyer et al, 2015).…”
