“…Screening for balance using timed single-leg stance with eyes opened and closed on stable or unstable surfaces typically involves a subject standing still with one leg while raising the opposite leg to varying degrees. 34 It could be done with the eyes opened or closed while standing on a firm surface or on foam pad, with each performance and condition timed. 35 This test is premised on the role of the central nervous system in processing afferent inputs from visual, vestibular, and somatosensory systems for balance tasks.…”

Aims: This review sought to determine the extent to which balance screening tests in dance medicine are representative of dance movements and to determine if such tests can be used to empirically track the effectiveness of balance-related injury rehabilitations in dancers. Methods: A five-step scoping review method was used. Multiple databases and reference lists of identified studies were searched to obtain original research published between 2000 and 2020 that described the balance screening tests used for data collection. Articles were excluded if they were: qualitative studies, reviews, opinion papers, consensus statements, conference proceedings, or used questionnaires to collect balance performance data. Results: Fifteen of the 31 studies included in this review used different models of force platforms in their balance screenings. The Star Excursion Balance Tests (SEBT) and its variants were used by 12 studies, single-leg stance with eyes opened or eyes closed on stable versus unstable surfaces was used by six studies, Airplane test (n = 6 studies), Pirouette Test (n = 3 studies), Romberg and variants of modified Romberg Tests (n = 3 studies) were also used for balance screening. Conclusion: Currently, there is no specific screening test that can be used empirically to screen balance performances among dancers. None of the currently available balance screening tests are specific enough for tracking the effectiveness of balance-related injury rehabilitation or for making a return to dance decision after balance-related injury rehabilitation.

Introduction: Professional dancers are committed to dancing despite their injuries and mood changes. Therefore, dancers’ balance ability should be evaluated as an objective indicator of the quality of their dance/dancing ability. Objective: We aimed to examine the relationship between the balance ability of professional ballet dancers and their psychological traits and states by serotonin polymorphism, using pressure and center of gravity sensors. Methods: Five female professional dancers participated in this three-month longitudinal pilot study. The dancers’ stress status was assessed each month on three conditional days to gauge stress conditions. Before and after their standard warm-up exercises, the dancers’ center of gravity was assessed while standing and posing in ballet-specific positions, and psychological questionnaire surveys were conducted to assess the level of anxiety and objective stress. After all observations were completed, serotonin polymorphism was analyzed as one of the psychological traits. Results: All participants possessed the s/s-type (short type) serotonin transporter gene promoter polymorphism, indicating high sensitivity to stress. Their average trait anxiety score was 50.80±8.47. However, all participants were able to be calm, had no injuries, and maintained a stable center of gravity throughout the study period. Conclusion: Throughout the study, from ordinary practice to the time of the approaching ballet performance, the participants maintained stable balance ability regardless of their psychological traits and states of mind. It is unlikely that reactions to stress and psychological traits affected professional dancers’ physicality. Thus, continuous assessment of the balance between mental and physical aspects enhances performance management.

A Wireless Sensor Network (WSN) is a small device that has batteries and radios to connect to the internet. The main problem with WSNs is a limited energy source, energy studies needed to ensure that these sensor nodes can last longer, especially since a lot of energy is wasted during idle listening, overhearing, and data collision that occurs at the medium access control (MAC) layer. The common mechanism used for saving energy in WSN, specifically at the MAC layer is the duty cycle schedule. Duty cycling coordinates sleep-wake time sensor nodes to maximize network lifetime while achieving specific application goals such as high throughput or low latency. Duty cycling of every node should be adjusted separately at any runtime depending on the network conditions to achieve desired delay guarantees and energy efficiency. Recently, a few adaptive duty cycle schemes were introduced, these schemes have reduced energy consumption by some degree, this leaves an open end to the degradation of the quality of service. In this study, adaptive duty cycles enhanced with a priority queue where packet size is the parameter to adjust the duty cycle in order to get efficient energy consumption. A variant of packet size tested to ensure optimum quality of services (QoS). These factors determine the duration of a node’s listen period for various packet transmission scenarios and requirements. As the result, the proposed Enhanced S-MAC (ESMAC) shows an improvement in the energy consumption and QoS compared to the default MAC protocol and S-MAC protocol. The success of this project will contribute to the performance improvement of sensing devices.
