Our primary intent in examining this literature was to investigate the modalities and procedures used by CAM clinicians to manage chronic LBP.Each of the papers discussed in this section provides one piece of a larger puzzle, demonstrating use rates in various settings and locations.Table 1 summarizes the results for the papers relating specifically to LBP, and also includes information on design and response rates.DJ808_feature.jpg' alt='Roland Jv 1010 Reference Manual' title='Roland Jv 1010 Reference Manual' />Table 1.Table of results for back pain papers.Noting that over 2.US sought chiropractic care 4, Hurwitz et al 5 examined the demographic and clinical characteristics of chiropractic patients as well as looked at visit rates in 6 sites located in the US and Canada.They chose 5 sites in the United States San Diego, Portland, Minneapolis St.Paul, Miami and Vancouver, Washington state and one in Canada Toronto as representing a range in options with regard to geography, chiropractor to populace ratio and scope of practice laws.Site specific chiropractic visit rates were calculated by multiplying the average number of visits for each chiropractor sampled by the number of chiropractors at that site and then dividing by the total population.SecurityStudy.

Kellner and Wellman 9 also looked at Toronto, Canada to examine the users of 5 modes of therapy chiropractors, acupuncturists, naturopaths, Reiki practitioners, and family physicians who are used as a baseline group.The authors found that in certain ways the chiropractic group differed strongly from the other 4 groups a more equal sex distribution, a higher level of education, a higher level of household income and a higher level involved in full time employment.Eighty seven percent of the chiropractic patients had sought care for a musculoskeletal health problem, with 7.Interestingly, 9.Walker and colleagues 1.Australian adults seeking care for low back pain, using a population based mail survey.The questionnaire provided cross sectional data that looked at past and current status of LBP, involving disability, prevalence, who respondents sought care from and demographic information.Respondents were stratified into 3 age groups 1.Other variables included socioeconomic status, smoking status, lifetime physical fitness, lifetime emotional distress and fear of LBP, among others.A total of 2. 76.Among its findings were that nearly 6.LBP in the last 6 months, with the largest percentage reporting grade I pain.Of those with low back pain, 4.The most frequent types of practitioners seen were general practitioners 2.Of those seeking chiropractic care, most were married, had educational levels that allowed them to work in basic or skilled jobs, were employed full time though just marginally higher than 5.Those with LBP or fearful that their LBP could affect their life were more likely to seek care women were more likely than men to do so as well.Shekelle and Brook 6 analyzed data from the RAND Health Insurance Experiment HIE to derive population based information on the use of chiropractic services.Here, the authors examined insurance claim forms for all fee for services patients who saw a chiropractor for care.They examined services provided and patient specified symptoms, and derived population based use rates per site.Use rate and services were calculated for both first and repeat visits.In this study, 5.HIE, representing 1.Repeat visits accounted for 8.The most frequent reason for care seeking was pain, swelling or injury to the back 4.Overall, the study demonstrated a visit rate for chiropractic of 4.This is lower than in other studies, though this is also older data than in other studies.Sherman et al 1. Though their interest was in understanding what kinds of therapies patients interested in entering clinical trials might be willing to consider, the results may potentially be generalizable to other populations.The study was based upon the results of 2.The patients were located in both Washington state and Boston, Massachusetts, members of a non profit health management agency.All suffered from chronic LBP.Of the therapies that were studied, the patient knowledge of each was rather low except in the case of chiropractic.Further, chiropractic had been used by the greatest percentage of patients 5.Knowledge and use of acupuncture, Tai Chi and meditation were lower.Those who used the services of chiropractors also noted treatment related discomfort or pain more than other groups.And most surveyed indicated they would be willing to use any of these alternative therapies if they were included in their health care plan and did not require any additional out of pocket expense.On the other hand, Caswell and West 1.Great Britain.
