요약The analysis of turning in clinical populations has increased with the improvement of wearable technology. The research surrounding turning metrics, while robust, is still lacking foundational work to understand its utility. This dissertation addressed some of the gaps in the literature. We conducted a scoping review to understand what turning metrics were associated with an increased risk for falls. Out of 13,113 records, 22 were selected for data extraction. From the included records, turning metrics, the populations that were investigated for turning deficits, and the assessment details were extracted.To test the utility of wearable sensors to discern between an unrestricted condition and a condition that restricted cervical motion, we collected turning data on healthy participants during activities of daily living. Significant differences were identified between conditions in both yaw and pitch plane turning metrics.Test-retest reliability of turning speed was assessed during a variety of turning tasks collected from 71 healthy participants with wearable sensors. Reliability of turning speed was good to excellent for most of the turn tasks across three body segments. However, the task which required participants to perform at their maximum safe speed, had the most varied reliability.To understand the relationship between age and turning speed and compare it to the relationship between age and gait speed, we analyzed these variables during a timed walk test in 271 healthy ambulators between the ages of 18-90. After applying a series of regression models, we discovered a linear negative relationship between age and turning speed. While gait speed did not decline until after age 65.Lastly, we documented the change in turning speed in participants with a vestibular schwannoma (VS) scheduled for resection. Overall, compared to healthy controls, participants with a VS performed turns more slowly prior to surgery. During the post-operative phase, participants reduced their turning speed which coincided with an increase in vestibular symptoms. After six weeks of vestibular rehabilitation, participants were turning at a speed similar to their pre-operative performance.Turning speed has proven to be a reliable and sensitive metric. This investigation will bolster new research into turning metrics as a clinical measure.
