Determine the impact of an 8-week mindfulness meditation program on disability, psychological function, and pain severity in community-dwelling older adults with chronic low back pain, and to test the education control program for feasibility.
Randomized controlled trial. Participants. Forty community-dwelling older adults with moderate low back pain or greater for at least the previous 3 months. Intervention. Participants were randomized to an 8-week meditation program or an 8-week education control program.
Disability, psychological function, and pain severity were assessed. The same measures were obtained for both groups at baseline, at the end of the program, and 4 months after program completion.
Sixteen participants (80%) completed the meditation program and 19 (95%) completed the education program. Both the meditation and control group improved on measures of disability, pain, and psychological function, both at program completion and 4-month follow-up. The differences between the two groups did not reach statistical significance. The meditation group practiced mindfulness meditation a mean of 5 days/week (range 1-7) and mean of 31 minutes/session (range 22-48). At 4 months follow-up 14/16 (88%) participants continued to meditate.
Both the intervention group and the education control group improved on outcome measures suggesting both programs had a beneficial effect. Participants continued to meditate on 4-month follow-up. The control program was feasible but not inert. Piloting the control program in mind-body research can inform the design of larger clinical trials.
确定为期 8 周的正念冥想方案对社区居住的慢性下背痛老年患者的残疾、心理功能和疼痛严重程度的影响，并检验教育对照方案的可行性。
随机对照试验。参与者：40 名社区居住的慢性下背痛或更严重的老年患者，至少持续 3 个月。干预：参与者随机分为 8 周冥想方案或 8 周教育对照方案。
16 名（80%）参与者完成了冥想方案，19 名（95%）参与者完成了教育方案。两组在基线、方案结束时和方案完成后 4 个月时均改善了残疾、疼痛和心理功能的评估指标。两组之间的差异无统计学意义。冥想组平均每周练习正念冥想 5 天（范围 1-7），每次练习 31 分钟（范围 22-48）。在 4 个月的随访中，14/16（88%）的参与者继续冥想。
干预组和教育对照组在结局评估指标上均有改善，这表明两种方案均有有益的效果。在 4 个月的随访中，参与者继续冥想。教育对照方案是可行的，但并非无效。在身心研究中试行对照方案可以为更大规模的临床试验设计提供信息。
