In older people with chronic non-specific low back pain (CNSLBP), what is the effect of a group-based exercise protocol compared with a waitlist control on pain intensity, disability, global perceived effect, frequency of falls, fear of falling and physical activity?
Randomised trial with concealed allocation and intention-to-treat analysis.
One hundred and twenty people aged ≥ 60 years with CNSLBP.
Participants were allocated to undertake 1-hour group exercise sessions, three times per week for 8 weeks or to a waitlist control.
The primary outcomes were pain intensity and disability. Secondary outcomes were the global perceived effect, frequency of falls, fear of falling and physical activity level. Data were collected at baseline, 8 weeks, 5 months and 12 months after randomisation.
Compared with control, group-based exercise reduced pain intensity on a 0-to-10 scale (MD -2.0, 95% CI -2.8 to -1.3) and disability on the 0-to-24 Roland-Morris Disability Questionnaire (MD -3.4, 95% CI -4.7 to -2.1). Group-based exercise also led to higher ratings of global perceived effect sustained through to 12 months and higher levels of physical activity at week 8. The effect on fear of falling was clearly negligible.
Group-based exercise has long-term benefits for pain intensity, disability and global perceived effect, with at least a short-term benefit for physical activity. Group-based exercise can be safely implemented in primary healthcare settings to manage CNSLBP in older people.

在患有慢性非特异性下腰痛（CNSLBP）的老年人中，与等待名单对照组相比，基于小组的运动方案对疼痛强度、功能障碍、总体感知效果、跌倒频率、跌倒恐惧和身体活动有何影响？
采用隐藏分配和意向性分析的随机试验。
120名年龄≥60岁的患有CNSLBP的人。
参与者被分配参加每周三次、每次1小时、为期8周的小组锻炼课程，或被分配到等待名单对照组。
主要结局为疼痛强度和功能障碍。次要结局为总体感知效果、跌倒频率、跌倒恐惧和身体活动水平。在随机分组后的基线、8周、5个月和12个月收集数据。
与对照组相比，基于小组的运动使0至10分制的疼痛强度降低（平均差 -2.0，95%置信区间 -2.8至 -1.3），并使0至24分的罗兰·莫里斯功能障碍问卷评分的功能障碍降低（平均差 -3.4，95%置信区间 -4.7至 -2.1）。基于小组的运动还导致总体感知效果评分持续提高至12个月，且在第8周时身体活动水平更高。对跌倒恐惧的影响显然可以忽略不计。
基于小组的运动对疼痛强度、功能障碍和总体感知效果具有长期益处，对身体活动至少有短期益处。基于小组的运动可在初级卫生保健机构安全实施，以管理老年人的CNSLBP。
