Sleep disturbances are common in people with dementia and increase with the severity of the disease. Sleep disturbances are complex and caused by several factors and are difficult to treat. There is a need for more robust and systematic studies dealing with sleep disturbances in older people with dementia. The aim of this study was to investigate effects from robot-assisted (Paro) group activity on sleep patterns in nursing home (NH) residents with dementia.
A cluster randomized controlled trial.
Special care units in 10 NH in Norway.
A total of 60 participants over 65 years with dementia were recruited. Thirty participants were recruited to the intervention group and 30 participants to the control group.
Participants participated in group activity with Paro for 30 minutes twice a week over 12 weeks or in control group (treatment as usual).
Sleep-wake patterns were assessed objectively by 7 days of wrist actigraphy before and after the intervention. Data were collected between March 2013 and September 2014. Data were analyzed using mixed models.
Positive effects on change in sleep were found in the intervention group as compared with the control group. The intervention group increased percentage of sleep efficiency, increased the amount of total sleep time and reduced number of nocturnal awakenings. In addition, a significant effect was found in reduced awakenings after sleep onset.
Social stimulation through engaging group activity could contribute to improved sleep in people with dementia in NH. Increased sleep efficiency and total sleep time, in addition to fewer night awakenings, affect central indicators of good sleep quality across the life span. Improved sleep quality will also affect quality of life and comorbidities in vulnerable groups. We believe group activity with Paro to be an accessible and feasible non-pharmacological treatment for those who enjoy Paro.
睡眠障碍在痴呆患者中很常见，并且随着疾病的严重程度而增加。睡眠障碍很复杂，由多种因素引起，且难以治疗。因此，需要更多针对老年痴呆症患者睡眠障碍的强有力和系统的研究。本研究旨在探讨机器人辅助（Paro）小组活动对疗养院（NH）老年痴呆症患者睡眠模式的影响。
集群随机对照试验。
挪威 10 家 NH 的特殊护理病房。
共招募了 60 名 65 岁以上患有痴呆症的参与者。其中 30 名参与者被招募到干预组，30 名参与者被招募到对照组。
参与者每周两次参加 Paro 小组活动 30 分钟，共 12 周，或参加对照组（常规治疗）。
在干预前后，通过 7 天腕动描记法客观评估睡眠-觉醒模式。数据收集于 2013 年 3 月至 2014 年 9 月之间。使用混合模型进行数据分析。
与对照组相比，干预组在睡眠变化方面有积极影响。干预组增加了睡眠效率的百分比，增加了总睡眠时间，减少了夜间觉醒次数。此外，还发现了入睡后觉醒次数减少的显著效果。
通过参与小组活动进行社交刺激可能有助于改善 NH 中痴呆症患者的睡眠。提高睡眠效率和总睡眠时间，减少夜间觉醒次数，会影响整个生命周期中良好睡眠质量的中心指标。改善睡眠质量也会影响弱势群体的生活质量和合并症。我们认为，对于喜欢 Paro 的人来说，小组活动与 Paro 相结合是一种可行的非药物治疗方法。
