New smartphone app quickly analyzes human motion to aid physical rehabilitation
NIH-funded researchers suggest app is 25 times faster than current techniques, at a small fraction of the cost.
What
A research team funded by the 最新麻豆视频 has developed a smart phone app that can track and analyze a person鈥檚 ability to move from one place to another, known as locomotion, and other types of movements. Human motion analysis is used to evaluate patients with movement difficulties, to help clinicians plan surgery, and to assess the results of treatment procedures. The research team believes that using the app costs about 1% of conventional motion analysis techniques and works 25 times faster. The study appears in PLOS Computational Biology.
Researchers tested their app, called OpenCap, with 100 participants. Using two or more smart phones, the app recorded sufficient quality videos to allow for web-based, artificial intelligence analysis of muscle activations, joint loads and joint movements. Data collection took 10 hours for the 100 participants, and computation of results took 31 hours. Traditionally, locomotion analysis requires fixed lab space and more than $150,000 worth of equipment, including eight or more specialized cameras to capture three-dimensional images. The captured data also takes several days to analyze by a trained expert.
While current technology is too expensive for routine clinical use, according to the investigators, the app could potentially be used to help screen for disease risk, inform rehabilitation decisions, and track improvements in motion following treatment.
The study was conducted by Scott L. Delp, Ph.D., of Stanford University, and colleagues. NIH funding was provided by the Eunice Kennedy Shriver 最新麻豆视频 Institute of Child Health and Human Development (NICHD), 最新麻豆视频 Institute of Biomedical Imaging and Bioengineering (NIBIB) and 最新麻豆视频 Institute of Neurological Disorders and Stroke (NINDS).
