背景：目前尚不清楚在住院康复治疗中是否可以连续佩戴可穿戴的心率传感器来评估心肺训练的反应。如果可行，这些传感器提供了一种低成本、低维护的方法来评估这种情况下的HR反应。我们确定了可穿戴传感器的可行性，用于评估住院患者在心肺训练区内对日间治疗活动的HR反应，该训练区等于最大HR(目标HR[THR])的55-80%，每周至少两次10分钟的比赛，每周3-5天。其次，我们确定了过度心率的发作次数(EHR和GT；80%的最大心率)。材料和方法：被诊断为中风、心脏疾病、骨科疾病、内科复杂情况或肺部疾病的44-80岁的受试者在住院康复期间日夜佩戴腕式心率传感器。对符合THR阈值并经历EHR发作的受试者的比例进行了量化。多元回归从年龄、性别、住院时间以及入院和出院时的运动功能来预测全速和全速心率的结果。结果：在所有受试者中，97,800 分钟的心率数据被分析。60%的受试者达到了心肺功能受益的Thr阈值。年龄是达到Thr阈值的天数百分比的唯一显著预测因素(R = 0.58，p= 0.024)。47%的受试者在至少1天内经历过EHR发作。没有受试者经历与传感器相关的不良事件，也没有因意外移除传感器而出现的方案偏差。结论：大多数受试者经历了足以获得心肺功能好处的HR增加。同样，大多数受试者都有EHR发作。可穿戴传感器用于持续评估HR反应是可行的，这表明在住院康复研究和治疗中扩大了机会。
Background:It is unclear whether wearable heart rate (HR) sensors can be worn continuously in inpatient rehabilitation to assess cardiorespiratory training response. If feasible, these sensors offer a low-cost low-maintenance method for assessing HR response in this setting. We determined feasibility of wearable sensors for assessing HR response to daytime therapy activities in inpatient rehabilitation within a cardiorespiratory training zone equal to 55–80% of maximal HR (target HR [THR]) for at least two 10-min bouts, 3–5 days per week. Secondarily, we determined episodes of excessive HR (EHR >80% of maximal HR).Materials and Methods:Subjects 44–80 years of age with diagnoses of stroke, cardiac disorders, orthopedic disorders, medically complex conditions, or pulmonary disorders wore wrist-mounted HR sensors day and night throughout inpatient rehabilitation. The proportion of subjects meeting THR thresholds and experiencing EHR episodes was quantified. Multiple regression predicted THR and EHR outcomes from age, sex, length of stay, and motor function at admission and discharge.Results:Across subjects, 97,800 min of HR data were analyzed. Sixty percent of subjects met THR thresholds for cardiorespiratory benefit. Age was the single significant predictor of percent of days meeting the THR threshold (R = 0.58,p= 0.024). Forty-seven percent of subjects experienced EHR episodes on at least 1 day. No subjects experienced sensor-related adverse events, and no protocol deviations occurred from inadvertent sensor removal.Conclusions:Most subjects experienced HR increases sufficient to obtain cardiorespiratory benefit. Likewise, most subjects had episodes of EHR. Wearable sensors were feasible for continuously assessing HR response, suggesting expanded opportunity in inpatient rehabilitation research and treatment.
