Measuring partner synchrony during salsa dancing and its relationship to changes in psychosocial domains

BackgroundDance is a promising rehabilitation adjunct but understanding the mechanisms through which dance improves physical and psychosocial well-being is necessary for implementation. This study investigated the feasibility of a measure of one possible mechanism: partner synchrony. Secondary objectives were to examine the relationships between partner synchrony, instructor ratings, and changes in psychosocial variables. MethodsParticipants wore an Inertial Measurement Unit (IMU) sensor during a salsa class that was video recorded. Partner synchrony was quantified with correlations of x, y, and z-axis acceleration between dancing pairs. Psychosocial variables were measured pre- and post-class. Salsa instructors rated partner synchrony from video recordings. Feasibility parameters included percentage of participants with data collected and sensor comfort. Pre-post changes were analyzed with Wilcoxon ranked tests and relationships were analyzed with Spearman correlations. ResultsData was collected for 23/24 (96%) participants and 17/24 (81%) reported the sensor was comfortable. All psychosocial variables improved from pre- to post-class. Partner synchrony was significantly associated with instructor ratings and change in positive and negative affect. ConclusionsAn IMU-based measure of dance partner synchrony is feasible, associated with ratings by dance instructors and related to changes in mood. The partner synchrony measure can be used to advance our understanding of dance as a therapeutic tool after its reliability is investigated.

Do we perform as well as we think we do? A systematic scoping review of self-evaluation of upper-extremity motor performance

The ability to self-evaluate motor performance or estimate performance errors is beneficial for motor learning or relearning in the context of neurologic injury. Some evidence suggests those with injury like stroke may be unable to accurately self-evaluate their performance; however, it is unclear if individuals who are absent of injury are accurate in this domain. We aimed to investigate the accuracy of self-evaluation and potential influencing factors by conducting a systematic search to identify literature involving the self- and objective-evaluation of upper-extremity motor tasks. Twenty-three studies satisfied inclusion criteria. Data revealed a moderate positive correlation between self- and objective evaluations across a variety of tasks, from trivial button pressing to specialized surgical suturing. Both under- and overestimation of performance was found across the papers. Key factors identified to influence the accuracy of self-evaluation were the task purpose, familiarity, difficulty, and whether an individual received a demonstration. This review identified some limitations in this field of research. Most notably, we found that very few studies have investigated the accuracy of self-evaluation of motor performance with the primary goal of comparison to objective performance. Many studies reported the data but did not make direct statistical comparisons. Moreover, due to inconsistencies between how self and objective-evaluations were conducted, we argue that in this area of investigation self-evaluation tools need to replicate the objective evaluation method, or at minimum the self-evaluation tool should ask questions specific to the construct of performance that is being measured objectively.

The effects of postural threat induced by a virtual environment on performance of a walking balance task.

Rapid motor learning may occur in situations where individuals perceive a threat of injury if they do not perform a task well. This rapid motor learning may be facilitated by improved motor performance and, consequently, more errorless practice. As a first step towards understanding the role of perceived threat on rapid motor learning, the purpose of this study was to determine how performance of a motor task is affected in situations where perceived threat of injury is high. We hypothesized that perceived threat of injury in a virtual environment would result in improved performance of a walking task (i.e., walking on a narrow beam). Results demonstrated that increased perceived threat of injury yielded slightly greater, but not statistically significant, balance performance in virtual environments (median percentage of successful steps: 78.8%, 48.3%, and 55.2% in the real low-threat, virtual low-threat, and virtual high-threat environments, respectively). These results may be partially attributed to habituation to threat over time and practice. If implemented carefully, virtual reality technology can be an effective tool for investigating walking balance in environments that are perceived as threatening.
