[Objective]To compare the efficacies of three types of acupuncture modalities on the pain magnitude and disability of chronic low back pain (LBP).
[Design]Single blind randomized controlled trial, three parallel arms.
[Setting]Outpatients of the Meiji University of Integrative Medicine Hospital.
[Subjects]Thirty-nine elderly patients (24 females, 15 males;age 71.2 ± 7.7) who suffered from LBP for at least six months.
[Interventions]Subjects were randomly allocated to one of three groups. Tender point group (TeP, n = 13) received to the tender point. Trigger point acupuncture group (TrP, n = 13) received to the trigger points. Sham acupuncture group (SM, n = 13) mimicked needling without insertion of the needle in the trigger point. Acupuncture sessions were performed once a week for five weeks.
[Main Outcome Measures]Pain intensity (visual analogue scale:VAS) and QOL (Roland-Morris Disability Questionnaire:RDQ).
[Results]At the end of the treatment period, significant improvement was observed on pain intensity and QOL in the TrP group alone (p < 0.01). However, there were significant differences in pain at the three month follow-up.
[Conclusion]These results suggest that trigger point acupuncture has a long-term effect on treatment for low back pain in aged patients.

[Objective] Although there is some evidence for the efficacy of trigger point acupuncture and tender point acupuncture treatments for chronic low back pain, differences between the therapeutic effect of trigger point needling and that of tender point needling remain unclear. We compared the therapeutic effects of trigger point acupuncture and tender point acupuncture treatment for chronic low pack pain in elderly patients.
[Design] Single-blind clinical controlled trial, quasi-randomized, 2 parallel arms.
[Methods] Nine patients, aged 65 or over, with chronic low back pain for at least 6 months were alternately allocated to the trigger point needling group (n=4) or tender point needling group (n=5). Patients received treatments once a week for five weeks. Outcome measures were pain intensity (Visual Analog Scale : VAS) and pain disability (Roland-Morris Disability Questionnaire : RDQ).
[Results] After the treatment period, VAS and RDQ values had improved significantly in the trigger point group, but there were no significant improvements in the tender point group.
[Conclusion] Differences in improvement between the trigger point and tender point groups seem to suggest that the trigger point needling was different from tender meridian point needling in respect to the therapeutic effect. Further studies are necessary to fully assess the efficacy of this treatment for chronic low back pain using a blinded or placebo control group.

OBJECTIVESThe Community Health Act came into effect in 1997 in Japan. This act altered the work system for public health nurses (PHNs) in public health centers (PHCs) nationwide from region-specific to service-specific work. Such major changes to working environment in the new system seem to be exposing PHNs to various types of stress. The present study examined whether prevalence of burnout is higher among PHNs in charge of mental health services (psychiatric PHNs) than among PHNs in charge of other services (non-psychiatric PHNs), and whether attributes of emergency mental health care systems in communities are associated with increased prevalence of burnout.

METHODSA questionnaire including the Pines burnout scale for measuring burnout was mailed to 525 psychiatric PHNs and 525 non-psychiatric PHNs. The 785 respondents included in the final analysis comprised 396 psychiatric PHNs and 389 non-psychiatric PHNs.

RESULTSPrevalence of burnout was significantly higher for psychiatric PHNs (59.2%) than for non-psychiatric PHNs (51.5%). When prevalence of burnout in each group was analyzed in relation to question responses regarding emergency service and patient referral systems, prevalence of burnout for psychiatric PHNs displayed significant correlations to frequency of cases requiring overtime emergency services, difficulties referring patients, and a feeling of "restriction".

CONCLUSIONSPrevalence of burnout is high among psychiatric PHNs, and inadequate emergency mental health service systems contribute to burnout among these nurses. Countermeasures for preventing such burnout should be taken as soon as possible.
