Skeletal bone age assessment is a common clinical practice to investigate endocrinology, genetic and growth disorders of children. However, clinical interpretation and bone age analyses are time-consuming, labor intensive and often subject to inter-observer variability.
Respiratory rate and phase are important information to assist the assessment of patients’ health in different clinical scenarios. Facial masks are usually employed to record respiratory waveforms, but they cause discomfort and obstruct the breathing of debilitated patients. Accelerometers have been proposed as an alternative to circumvent such drawbacks; however, their best placement and effectiveness in different postures for different subjects were not previously investigated.
