Little is known about the post-discharge outdoor activities of people who have incurred severe traumatic brain injury (TBI). This study used a body-worn global positioning system (GPS) device to determine the outdoor activity per day performed by this population. Additionally, this study examined the association that mobility, time since injury and injury severity had with levels of outdoor physical activity.
Seventeen people with TBI and 15 control subjects wore a GPS device for between 3-7 days to monitor their outdoor activity. Based on the individual's location and speed of movement the outdoor physical activity in minutes per day was derived. Assessments of duration of outdoor activity between groups, and the relationship that duration of outdoor activity had with results on the high-level mobility assessment tool, length of post-traumatic amnesia, and time since injury were performed. No significant (p = 0.153, effect size = 0.26) difference in time spent in outdoor physical activity was observed between the TBI (median[IQR] = 19[3-43]mins) and control (median[IQR] = 50[18-65]mins) group. Interestingly, 35% of TBI subjects performed <10 mins of outdoor activity per day compared to 13% of the control group. The TBI group also recorded three of the four highest values for outdoor physical activity. Higher levels of mobility were associated with more outdoor activity (Spearman's rho = 0.443, p = 0.038). No other significant associations were observed.
While preliminary, our results indicate that a sub-group of people with TBI exists who restrict their outdoor activities. GPS has potential as an activity tracking tool, with implications for rehabilitation and exercise prescription.
对于遭受严重创伤性脑损伤 (TBI) 的人在出院后的户外活动知之甚少。本研究使用穿戴式全球定位系统 (GPS) 设备来确定这一人群每天的户外活动量。此外，本研究还探讨了移动能力、受伤时间和损伤严重程度与户外活动水平之间的关系。
17 名 TBI 患者和 15 名对照者佩戴 GPS 设备 3-7 天，以监测他们的户外活动。根据个人的位置和移动速度，得出每天户外活动的分钟数。对两组之间的户外活动持续时间进行评估，并对户外活动持续时间与高级移动能力评估工具的结果、创伤后遗忘时间和受伤时间之间的关系进行评估。TBI 组（中位数 [IQR] = 19 [3-43] 分钟）和对照组（中位数 [IQR] = 50 [18-65] 分钟）之间在户外体力活动时间上无显著差异（p = 0.153，效应大小 = 0.26）。有趣的是，35%的 TBI 患者每天的户外活动时间不足 10 分钟，而对照组只有 13%。TBI 组还记录了户外体力活动的四个最高值中的三个。较高的移动能力与更多的户外活动有关（Spearman's rho = 0.443，p = 0.038）。未观察到其他显著关联。
虽然初步结果表明，存在一小部分 TBI 患者限制他们的户外活动。GPS 作为一种活动跟踪工具具有潜力，对康复和运动处方具有影响。
