The aim of the study was to examine the effect of a daily pain diary on recovery from acute low back sprain.
Summary Of Background Data:
Pain diaries are often recommended to or used by patients suffering with acute lumbar (low back) sprain. Diaries have been shown to be associated, however, with a slower rate of recovery after whiplash (neck) injury. The effect of diary use on recovery from low back injury is unknown. Subjects with acute lumbar (low back) sprain were randomly assigned to one of the two groups: a diary group and control group. A total of 58 out of 62 initially recruited subjects were seen in follow-up 3-month post-injury, 29 in the diary group, and 29 in the control group. Data were gathered within 1 week of injury on sex, age, and Oswestry Disability Questionnaire (ODQ) scores. The diary group was asked then to keep a record of their overall pain experience, rating their pain on a scale of 1-10 on a daily basis for 4 weeks. At the outset, both groups had similar mean age, sex distribution, and mean ODQ scores. After 4 weeks of pain diary use, fewer diary group subjects reported recovery at 3 months compared with the control group (52 vs. 79 %, respectively, p < 0.05). The use of a pain diary for 4 weeks in acute lumbar sprain subjects is associated with a reduced rate of recovery.
