A new Curtin-developed wearable sensor system has tracked the movement of dancers, providing valuable insights into how they adapt to dance through disabling pain. The study, published in PLOS ONE, analysed the movement of 52 pre-professional ballet and contemporary dance students from the Western Australian Academy of Performing Arts (WAAPA). The wearable sensor system was developed as part of a collaboration between the Curtin School of Allied Health and the Curtin Institute for Computation.
Lead researcher PhD student and former professional ballerina Danica Hendry, from the Curtin School of Allied Health, said that while almost all dancers experienced pain, only half of them had to stop or modify their movements. She noted that fifty out of the 52 dancers said they experienced pain, with 26 reporting that this pain impacted their training/performance. Our findings indicate that the dancers are often able to continue dancing when in pain, and do so by adapting their movements, such as reducing their load.
Despite a high prevalence of musculoskeletal pain, dancers’ levels of pain severity and disability were generally low with the lower back and ankle/foot reported as most common. It was noted that existing measures, such as activity diaries and schedules, did not capture the specific movements that the dancers performed. Previous research exploring dancers’ movement quantity has focused on measuring workload by simply looking at the daily time spent dancing, Ms Hendry said.
Wearable sensors have more recently been used to determine the exercise intensity of dancers during their daily training, demonstrating that while dancers participate in several hours of training per day, the majority of this time is spent doing ‘low to medium intensity’ exercise. While the two approaches offer valuable insights, until now, there has been no way to provide detailed information such as the number of repetitions of movements.
Research supervisor and John Curtin Distinguished Professor Peter O’Sullivan, also from the Curtin School of Allied Health, was proud to have been involved with the creation of a wearable sensor system that could detect the movement quantity and quality of dancers. He noted that while athlete monitoring systems are commonly applied in many elite sports, it’s only recently emerging within the field of dance, and only assess the quantity of dancers’ movement. In recent years, substantial attention has been placed on quantifying athlete training to assist in understanding the development and experience of pain and disability, he added.
The future application of wearable sensor technology provides the opportunity for clinicians to gain a deeper insight into the inter-relationships between pain, disability, and movement in athletic populations, to better inform person-centred care. However, there remain a few challenges of the wearable sensor system that must be addressed before more sophisticated applications can be undertaken.
The market for wearable sensors has registered a CAGR of 19.15% during the forecast period (2021–2026). Primarily, as a result of digitalisation, the electronic industry has prospered significantly. Thereby, driving the market for wearable technology devices, which are widely used for self-health monitoring applications.
Recently, wearable devices have received considerable interest owing to their potential in a wide variety of applications. Increased research efforts are being geared toward the non-invasive monitoring of human health, as well as activity parameters. A wide range of wearable sensors is being developed for real-time non-invasive monitoring.
