“…In Lind et al [ 71 ] for example, visual observations of the participants indicated that the participants sometimes bent their knees and hence moved the upper body vertically, which likely increases the metabolic load. Additionally, there is also a possibility that biofeedback introduces other unintended adverse effects, for example, observed reduced performance as a result of biofeedback, indicating increased cognitive load [ 115 ].…”

Work-related diseases and disorders remain a significant global health concern, necessitating multifaceted measures for mitigation. One potential measure is work technique training utilizing augmented feedback through wearable motion capture systems. However, there exists a research gap regarding its current effectiveness in both real work environments and controlled settings, as well as its ability to reduce postural exposure and retention effects over short, medium, and long durations. A rapid review was conducted, utilizing two databases and three previous literature reviews to identify relevant studies published within the last twenty years, including recent literature up to the end of 2023. Sixteen studies met the inclusion criteria, of which 14 were of high or moderate quality. These studies were summarized descriptively, and the strength of evidence was assessed. Among the included studies, six were rated as high quality, while eight were considered moderate quality. Notably, the reporting of participation rates, blinding of assessors, and a-priori power calculations were infrequently performed. Four studies were conducted in real work environments, while ten were conducted in controlled settings. Vibration feedback was the most common feedback type utilized (n = 9), followed by auditory (n = 7) and visual feedback (n = 1). All studies employed corrective feedback initiated by the system. In controlled environments, evidence regarding the effectiveness of augmented feedback from wearable motion capture systems to reduce postural exposure ranged from strong evidence to no evidence, depending on the time elapsed after feedback administration. Conversely, for studies conducted in real work environments, the evidence ranged from very limited evidence to no evidence. Future reach needs are identified and discussed.

“…In terms of performance, according to the Table 2, advanced sEMG and VR/AR methods provide more complete feedback but are less accessible due to their complexity. On the other hand, wearable sensors and visual and auditory feedback devices have slightly different performance, are more accessible, and are more popular while requiring less specific settings [38].…”

Forward Head Posture (FHP) is when the head leans forward due to factors such as heavy backpacks or poor computer ergonomics. FHP can lead to neck strain and discomfort as well as potential long-term issues such as arthritis. Treatment options include specialized exercises, orthopedic devices, manual therapy, physical exercises, and visual feedback techniques, along with guidance from specialists in physical medicine and rehabilitation. In this study, a visual feedback-based approach was used to address FHP in female students. The study spanned ten days and included a visual feedback group and a control group. The results showed significant improvements in maximum head angle deviation in the visual feedback group compared to the control group; however, there was no significant change in the DFA number, indicating stability in policy control by the central nervous system. The study demonstrated that visual feedback sessions led to immediate benefits, with participants progressively acquiring skills involving the maintenance of proper head positioning. The test results indicated that the neck angle decreased to less than 15 degrees, indicating a return to a normal state. The versatility of the developed affordable and easy-to-use device and the potential for using smartphone motion sensors for similar visual feedback systems are discussed in this paper as well. The study suggests the promising potential of visual feedback in healthcare, including remote monitoring and smartphone-based solutions.

BackgroundA surgical team works in a high‐performance environment and is exposed to stress. Mindfulness practice is evidenced to reduce symptoms of stress, as well as burnout, which is high amongst health workers. The operating theatre is unique, with many job‐roles, needs and time‐critical tasks. It is plausible that group mindfulness may benefit the surgical team. This evaluates the take‐5 theatre brief, consisting of a ‘check‐in’ and short breathwork, when used by two surgical teams as part of the regular theatre team brief.ApproachThe take‐5 theatre brief was evaluated using domains of acceptability and implementation. Data were collected at two district general hospitals in the United Kingdom using 5‐point Likert scales hosted on electronic surveys Thematic analysis was performed of participant voice notes, strategic meeting notes and transcripts of interviews between key informants.EvaluationThere were 17 participants. Ten were from site A (59%), with the remainder being from site B (41%) and covered a range of roles within the theatre team. Participants found the take‐5 theatre brief helpful (median Likert 5) and felt that it would benefit themselves (median Likert 5) as well as the team (median Likert 5) and that it fitted into the day easily (median Likert 4). There was a high demand, no financial investment was required and overall it was easy to implement; however, it became challenged in theatre lists that were late to start.ImplicationThe take‐5 theatre brief is an acceptable initiative for these two operating theatre teams.
