Attitudes and behaviors of chiropractic interns toward occupational history taking

OBJECTIVE

This study uses a pre- and post-training program evaluation of chiropractic interns to (1) describe changes in their frequency of occupational history taking before and after a 1-hour training and (2) to document the attitudes and beliefs regarding occupational health and history taking.

METHODS

All chiropractic interns at 1 clinic location completed questionnaires assessing their attitudes and perceptions regarding documenting the occupational history of their patients each trimester they were enrolled in the study. Each intern enrolled in the study for 2 or more trimesters participated in a 1-hour-long training session on taking an occupational history. The supervising clinician independently evaluated charting behaviors of interns for the duration of the study.

RESULTS

The supervising clinician assessed 20 interns' level of documenting occupational history for 202 new patient or reexamination visits. A majority of interns (85% at baseline) were interested in occupational health, and 80% believed that occupational history taking was "very important." Intern charting behaviors increased after training related to documentation of past occupation (62.9% from 32.4%) and relating the chief complaint to work (59.7% from 30.0%). Detailed occupational history taking remained low throughout the study but demonstrated a doubling in documentation after training (16.1% from 8.6%).

CONCLUSION

Chiropractic interns and clinicians should be adequately trained in occupational health history documentation practices as they are likely to care for work-related injuries. Short training modules appear to be effective in demonstrating small changes in documentation related to occupational history taking.

Shoe Orthotics for the Treatment of Chronic Low Back Pain: A Randomized Controlled Trial

OBJECTIVES

To investigate the efficacy of shoe orthotics with and without chiropractic treatment for chronic low back pain compared with no treatment.

DESIGN

Randomized controlled trial.

SETTING

Integrative medicine teaching clinic at a university.

PARTICIPANTS

Adult subjects (N=225) with symptomatic low back pain of ≥3 months were recruited from a volunteer sample.

INTERVENTIONS

Subjects were randomized into 1 of 3 treatment groups (shoe orthotic, plus, and waitlist groups). The shoe orthotic group received custom-made shoe orthotics. The plus group received custom-made orthotics plus chiropractic manipulation, hot or cold packs, and manual soft tissue massage. The waitlist group received no care.

MAIN OUTCOME MEASURES

The primary outcome measures were change in perceived back pain (numerical pain rating scale) and functional health status (Oswestry Disability Index) after 6 weeks of study participation. Outcomes were also assessed after 12 weeks and then after an additional 3, 6, and 12 months.

RESULTS

After 6 weeks, all 3 groups demonstrated significant within-group improvement in average back pain, but only the shoe orthotic and plus groups had significant within-group improvement in function. When compared with the waitlist group, the shoe orthotic group demonstrated significantly greater improvements in pain (P<.0001) and function (P=.0068). The addition of chiropractic to orthotics treatment demonstrated significantly greater improvements in function (P=.0278) when compared with orthotics alone, but no significant difference in pain (P=.3431). Group differences at 12 weeks and later were not significant.

CONCLUSIONS

Six weeks of prescription shoe orthotics significantly improved back pain and dysfunction compared with no treatment. The addition of chiropractic care led to higher improvements in function.

Clarifying Definitions for the Massage Therapy Profession: the Results of the Best Practices Symposium

BACKGROUND

Massage therapists are at times unclear about the definition of massage therapy, which creates challenges for the profession. It is important to investigate the current definitions and to consider the field as a whole in order to move toward clarity on what constitutes the constructs within the profession.

PURPOSE

To determine how a sample of experts understand and describe the field of massage therapy as a step toward clarifying definitions for massage and massage therapy, and framing the process of massage therapy practice.

SETTING

A two-day symposium held in 2010 with the purpose of gathering knowledge to inform and aid in the creation of massage therapy best practice guidelines for stress and low back pain.

PARTICIPANTS

Thirty-two experts in the field of massage therapy from the United States, Europe, and Canada.

DESIGN

Qualitative analysis of secondary cross-sectional data using a grounded theory approach.

RESULTS

Three over-arching themes were identified: 1) What is massage?; 2) The multidimensional nature of massage therapy; and 3) The influencing factors on massage therapy practice.

DISCUSSION

The data offered clarifying definitions for massage and massage therapy, as well as a framework for the context for massage therapy practice. These clarifications can serve as initial steps toward the ultimate goal of creating new theory for the field of massage therapy, which can then be applied in practice, education, research, and policy.

CONCLUSIONS

Foundational research into how experts in the profession understand and describe the field of massage therapy is limited. Understanding the potential differences between the terms massage and massage therapy could contribute to a transformation in the profession in the areas of education, practice, research, policy and/or regulation. Additionally, framing the context for massage therapy practice invites future discussions to further clarify practice issues.

Exploratory Analysis of Clinical Predictors of Outcomes of Nonsurgical Treatment in Patients With Lumbar Spinal Stenosis

OBJECTIVE

The purpose of this study was to explore potential baseline physical examination and demographic predictors of clinical outcomes in patients with lumbar spinal stenosis.

METHODS

This was a secondary analysis of data obtained from a pilot randomized controlled trial. Primary and secondary outcome measures were the Swiss Spinal Stenosis (SSS) Questionnaire and visual analog scale (VAS) for leg pain. Multiple regression models were used to assess 2 different outcomes: SSS at completion of care and VAS at completion of care. Separate regression models were built for each of the 2 outcomes to identify the best subset of variables that predicted improvement. Predictors with a significant contribution were retained in a final "best" model.

RESULTS

Three variables were identified as having an association with SSS score at completion of care: baseline SSS score, qualitative description of leg pain, and age (adjusted R(2) = 33.2). Four variables were identified as having an association with VAS score at completion of care: baseline VAS score, qualitative description of leg pain, body mass index, and age (adjusted R(2) = 38.3).

CONCLUSION

This study provides preliminary evidence supporting an association between certain baseline characteristics and nonsurgical clinical outcomes in patients with lumbar spinal stenosis.

Process for massage therapy practice and essential assessment

BACKGROUND

Little evidence exists about processes in massage therapy practice. Investigating current frameworks is warranted. This qualitative study is a secondary data analysis using grounded theory to understand how massage therapy experts describe massage therapy practice.

METHODS

31 massage therapy experts were invited to a 2-day symposium to discuss best practices for the profession. Through qualitative analysis, memoing, and discussion, the data were summarized into themes.

RESULTS

Three themes were identified around massage therapy practice: 1) client centered, 2) structure for practice, and 3) influencing factors. Each theme is clarified and expanded.

DISCUSSION

Conceptual models were developed for research and clinical practice and a definition for massage therapy practice was identified. Challenges and limitations are discussed.

CONCLUSION

The goal of providing these models is to give massage therapists tools to deliver the best possible care. The models need testing to see if they help advance the profession.

A pilot randomized controlled trial of flexion-distraction dosage for chiropractic treatment of lumbar spinal stenosis

OBJECTIVE

The purpose of this pilot clinical trial was to assess the feasibility of recruiting older adults with lumbar spinal stenosis (LSS) into a clinical trial that used different dosages of flexion-distraction manipulation.

METHODS

This randomized controlled trial used a 4-group design. Three groups consisted of chiropractic flexion-distraction manipulation applied at different dosages (8, 12, or 18 treatments). The fourth group was given 8 treatments of placebo care. Feasibility measures included recruitment goals, adherence to various treatment schedules, credibility of the placebo treatment, and rates of adverse events. The primary outcome measure was the Swiss Spinal Stenosis Questionnaire, a validated self-report of LSS symptom severity and physical function.

RESULTS

The recruitment and adherence goals of the study were met with a total of 60 subjects randomized (n = 15 per group) and most subjects attending at least 75% of their scheduled visits. No adverse events were reported by any of the subjects in the trial. Our placebo treatment did not appear to be credible; most subjects correctly guessed that they were receiving a placebo treatment. Between-group effect size estimates were small, indicating larger samples are needed for future studies.

CONCLUSION

This pilot study showed that it is feasible to recruit patients with LSS and that most subjects will adhere to a 6-week treatment schedule. The information gained from this trial will be useful to inform the design of larger trials.

Prevalence of nonmusculoskeletal versus musculoskeletal cases in a chiropractic student clinic

Objective : We sought to identify the percentage of nonmusculoskeletal and musculoskeletal conditions treated by interns in the National University of Health Sciences (NUHS) Student Clinic compared to chiropractic and allopathic health care professionals. Methods : The information gathered was taken from the charts of patients treated in the fall trimester, dated September 12, 2011 through December 9, 2011. The data collected included ICD-9 codes for the conditions treated, the number of patient visits, age, and gender, and was evaluated using Microsoft Excel. Results : Over half of the 113 eligible patients were women with a mean patient age of 28 years, an average of three treated diagnoses, and a mean of seven treatments. Those treated only for musculoskeletal conditions totaled 52% of the patients; 48% of the patients were treated for nonmusculoskeletal conditions, or musculoskeletal plus nonmusculoskeletal conditions. Conclusion : The NUHS Student Clinic interns are treating a greater percentage of nonmusculoskeletal conditions and a lesser percentage of musculoskeletal conditions than practicing chiropractic physicians. The student interns also treat a lesser percentage of nonmusculoskeletal and a greater percentage of musculoskeletal conditions than allopathic practitioners. This comparison would suggest that NUHS is nearing its institutional goal of training its student interns as primary care practitioners.

Cox decompression chiropractic manipulation of a patient with postsurgical lumbar fusion: a case report

OBJECTIVE

The purpose of this case report is to describe a patient with an L5/S1 posterior surgical fusion who presented to a chiropractic clinic with subsequent low back and leg pain and was treated with Cox decompression manipulation.

CLINICAL FEATURES

A 55-year-old male postal clerk presented to a private chiropractic practice with complaints of pain and spasms in his low back radiating down the right buttock and leg. His pain was a 5 of 10, and Oswestry Disability Index score was 18%. The patient reported a previous surgical fusion at L5/S1 for a grade 2 spondylolytic spondylolisthesis. Radiographs revealed surgical hardware extending through the pedicles of L5 and S1, fusing the posterior arches.

INTERVENTION AND OUTCOME

Treatment consisted of ultrasound, electric stimulation, and Cox decompression manipulation (flexion distraction) to the low back. After 13 treatments, the patient had a complete resolution of his symptoms with a pain score of 0 of 10 and an Oswestry score of 2%. A 2-year follow-up revealed continued resolution of the patient's symptoms.

CONCLUSIONS

Cox chiropractic decompression manipulation may be an option for patients with back pain subsequent to spinal fusion. More research is needed to verify these results.

A possible correlation between vitamin D deficiency and loss of smell: 2 case reports

OBJECTIVE

The purpose of this report is to present 2 cases of diminished olfaction that improved with increasing serum levels of vitamin D3.

CLINICAL FEATURES

Both patients were under the care of medical and chiropractic physicians for various complaints. A 47-year-old hyposmic woman was diagnosed with vitamin D deficiency who incidentally noticed a progressive return of her sense of smell while taking vitamin D supplements as prescribed by her medical doctor. A 34-year-old anosmic woman noticed a direct relationship with her ability to smell and vitamin D3 supplementation.

INTERVENTION AND OUTCOME

Treatment for the first patient consisted of vitamin D supplementation of 10 000 IU a day. Her serum D3 levels increased substantially over a period of 8 months, at which time she reported a marked improvement in her sense of smell. The second patient was prescribed 50 000 IU of vitamin D a week; and she reported an increased ability to smell, although only the strongest of odors.

CONCLUSION

A link between hypovitaminosis D and a diminished sense of smell was noted in these 2 individuals.

Prevalence of nonmusculoskeletal versus musculoskeletal cases in a chiropractic student clinic

Methods : The information gathered was taken from the charts of patients treated in the fall trimester, dated September 12, 2011 through December 9, 2011. The data collected included ICD-9 codes for the conditions treated, the number of patient visits, age, and gender, and was evaluated using Microsoft Excel. Results : Over half of the 113 eligible patients were women with a mean patient age of 28 years, an average of three treated diagnoses, and a mean of seven treatments. Those treated only for musculoskeletal conditions totaled 52% of the patients; 48% of the patients were treated for nonmusculoskeletal conditions, or musculoskeletal plus nonmusculoskeletal conditions. Conclusion : The NUHS Student Clinic interns are treating a greater percentage of nonmusculoskeletal conditions and a lesser percentage of musculoskeletal conditions than practicing chiropractic physicians. The student interns also treat a lesser percentage of nonmusculoskeletal and a greater percentage of musculoskeletal conditions than allopathic practitioners. This comparison would suggest that NUHS is nearing its institutional goal of training its student interns as primary care practitioners.

Large C4/5 spondylotic disc bulge resulting in spinal stenosis and myelomalacia in a Klippel-Feil patient

OBJECTIVES

The purpose of this report is to document a case of cervical spinal stenosis and myelomalacia in a patient with Klippel-Feil (KF) syndrome with a large C4/5 disc bulge presenting with cervical radiculopathy.

SUBJECT

A 39-year-old man was referred to a private chiropractic practice for a consultation. He complained of limited motion in his neck with pain and numbness radiating down both arms and left leg. Diagnostic imaging revealed KF syndrome and a large spondylotic disc bulge at C4/5 compressing the cord and causing myelomalacia. A plethora of symptoms and objective findings associated with KF syndrome were also present.

RESULTS

After reviewing the previous diagnostic imaging, examining this patient, and discovering that upper motor neuron pathological reflexes were present, the patient was recommended to proceed with the surgical intervention as recommended by his neurosurgeon. No chiropractic care was rendered.

CONCLUSIONS

This patient presented with primary complaints consistent with cervical radiculopathy. However, due to the severity of the neurologic findings and presence of myelomalacia, the patient was not treated. The patient had not previously been diagnosed with KF syndrome, although he presented clinically with many of the congenital issues commonly associated with the condition. This case demonstrates the vital importance of differential diagnostic skills as well as the need to continue fostering improved communication and integration of care among various clinical disciplines for patients presenting with challenging symptoms.

Distribution of cavitations as identified with accelerometry during lumbar spinal manipulation

OBJECTIVE

This project determined the location and distribution of cavitations (producing vibrations and audible sounds) in the lumbar zygapophyseal (Z) joints that were targeted by spinal manipulative therapy (SMT).

METHODS

This randomized, controlled, clinical study assessed 40 healthy subjects (20 men, 20 women) 18 to 30 years of age who were block randomized into SMT (group 1, n = 30) or side-posture positioning only (group 2; control, n = 10) groups. Nine accelerometers were placed on each patient (7 on spinous processes/sacral tubercles of L1-S2 and 2 placed 3 cm left and right lateral to the L4/L5 interspinous space). Accelerometer recordings were made during side-posture positioning (groups 1 and 2) and SMT (group 1 only). The SMT was delivered by a chiropractic physician with 19 years of practice experience and included 2 high-velocity, low-amplitude thrusts delivered in rapid succession. Comparisons using χ(2) or McNemar test were made between number of joints cavitating from group 1 vs group 2, upside (contact side for SMT) vs downside, and Z joints within the target area (L3/L4, L4L5, L5/S1) vs outside the target area (L1/L2, L2/L3, sacroiliac).

RESULTS

Fifty-six cavitations were recorded from 46 joints of 40 subjects. Eight joints cavitated more than once. Group 1 joints cavitated more than group 2 joints (P < .0001), upside joints cavitated more than downside joints (P < .0001), and joints inside the target area cavitated more than those outside the target area (P < .01).

CONCLUSIONS

Most cavitations (93.5%) occurred on the upside of SMT subjects in segments within the target area (71.7%). As expected, SMT subjects cavitated more frequently than did subjects with side-posture positioning only (96.7% vs 30%). Multiple cavitations from the same Z joints had not been previously reported.

Shoe orthotics for the treatment of chronic low back pain: a randomized controlled pilot study

OBJECTIVES

The purpose of this pilot study was to investigate the feasibility of a randomized clinical trial of shoe orthotics for chronic low back pain.

METHODS

The study recruited 50 patients with chronic low back pain through media advertising in a midwestern suburban area. Medical history and a low back examination were completed at a chiropractic clinic. Subjects were randomized to either a treatment group receiving custom-made shoe orthotics or a wait-list control group. After 6 weeks, the wait-list control group also received custom-made orthotics. This study measured change in perceived pain levels (Visual Analog Scale) and functional health status (Oswestry Disability Index) in patients with chronic low back pain at the end of 6 weeks of orthotic treatment compared with no treatment and at the end of 12 weeks of orthotic treatment.

RESULTS

This study showed changes in back pain and disability with the use of shoe orthotics for 6 weeks compared with a wait-list control group. It appears that improvement was maintained through the 12-week visit, but the subjects did not continue to improve during this time.

CONCLUSIONS

This pilot study showed that the measurement of shoe orthotics to reduce low back pain and discomfort after 6 weeks of use is feasible. A larger clinical trial is needed to verify these results.

Pilot study of the effect of a limited and extended course of chiropractic care on balance, chronic pain, and dizziness in older adults

OBJECTIVE

The purpose of this study was to collect preliminary information on the effect of a limited and extended course of chiropractic care on balance, chronic pain, and associated dizziness in a sample of older adults with impaired balance.

METHODS

The authors conducted a randomized pilot study targeting a sample size of 30, comparing 2 schedules of chiropractic care to a no-treatment group. Group 1 (limited schedule) was treated for 8 weeks, group 2 (extended schedule) was treated for 8 weeks and then once per month for 10 months, and group 3 received no treatment. Assessments were made at baseline and 1, 2, 6, and 12 months later. The primary outcome was changed in the Berg Balance Scale (BBS) from baseline to 1 year. Changes in the Pain Disability Index and Dizziness Handicap Index were also measured.

RESULTS

Thirty-four patients were enrolled, 13 in group 1, 15 in group 2, and 6 in group 3. Only 5 had baseline BBS scores less than 45, indicating increased risk for falls. There were no treatment-related adverse events. Nine patients dropped out by 1 year. No significant differences within or between groups in median BBS from baseline to 12 months were observed. Median Pain Disability Index scores improved more from baseline to 1 year in group 2 compared with groups 1 and 3 (P = .06, Kruskal-Wallis test). For the 9 patients with dizziness, a clinically significant improvement in Dizziness Handicap Index scores of groups 1 and 2 was observed at 1 month and remained lower than baseline thereafter; this was not true of group 3.

CONCLUSION

Further investigation of the possible benefit of chiropractic maintenance care (extended schedule) for balance and pain-related disability is feasible and warranted, as well as both limited and extended schedules for patients with idiopathic dizziness.

Clinical trial variability: quality control in a randomized clinical trial

INTRODUCTION

A major issue in clinical trials in manual medicine is treatment variability. The challenge is to insure that the bounded treatment options are both representative of field practitioner behavior and consistent among research clinicians. This investigation assesses the treatment comparability of field practitioners and research clinicians, for a flexion-distraction treatment procedure, as quality control for a randomized clinical trial.

METHODS

Using a series of vignettes, we studied the level of agreement of treatment protocols between field clinicians, research clinicians and a reference clinician regarding treatment location, range of motion during treatment, and number of repetitions used within the flexion-distraction protocol.

RESULTS

Results indicated that reliability around decision making for anticipated location of spinal treatment was highest regardless of clinician group. For the research clinicians this level of agreement was ICC=0.88. Decision-making for treatment direction was second highest, at kappa=0.64 for the research clinicians. Reliability around the number of repetitions is poor ranging from ICC=0.18 to 0.34 depending on clinician type.

DISCUSSION

Understanding the disparity in treatment protocols is of value in the construction and maintenance of quality control in an actual randomized clinical trial setting. More work was recommended in the preparation of clinical trials and the understanding of clinical decision-making because these disparate factors may dramatically impact the generalizability of clinical trial results.

Patient perceptions of chiropractic treatment for primary care disorders

OBJECTIVE

Although some surveyed groups of chiropractors consider themselves qualified as primary care providers, consumer attitudes of such may affect practice success. The purpose of this study is to determine chiropractic patients' perception of chiropractors as primary care providers and to determine what disorders patients believe chiropractors can treat.

METHODS

A 2-page survey was developed to collect information from current chiropractic patients at a teaching chiropractic clinic in the United States. Questions included (1) brief patient demographic information, (2) whether their chiropractor was their primary care physician, and (3) patient beliefs about chiropractors assessing and treating conditions that are common to a primary care medical practice. Conditions listed in the survey were based on a previous study on primary care medical physicians' practices. The sample of chiropractic patients was divided into suburban, urban, and chiropractic university-affiliated patients.

RESULTS

There were 163 subjects who responded to this survey for a 58% response rate. Only 19% (30/157) saw their chiropractor as their primary care physician. However, for each 'primary care condition' listed, the percent of patients who affirmed that chiropractors could treat the condition varied greatly with many conditions showing an affirmative response of higher than 50% especially in the urban and university-affiliated patient groups. All patients overwhelmingly believed that chiropractors could treat musculoskeletal conditions.

CONCLUSIONS

Patients have varied views of what chiropractors can and cannot treat. Further studies are needed to determine the effectiveness of chiropractic treatment for specific primary care disorders. The results of such studies may be the determining influence for public and physician opinion on the appropriateness of chiropractic care for these conditions.

One-year follow-up of a randomized clinical trial comparing flexion distraction with an exercise program for chronic low-back pain

OBJECTIVE

Flexion distraction is a commonly used form of chiropractic care with chiropractor utilization rates of 58%. However, no previous randomized clinical trial has assessed the effectiveness of this form of care. The objective of this investigation was to compare the pain and disability during the year after active care based on treatment group allocation (Flexion Distraction versus Exercise Program).

STUDY DESIGN

Randomized clinical trial, follow-up.

SUBJECTS

Two hundred and thirty-five (235) subjects who were previously randomized to either chiropractic care (flexion distraction) or physical therapy (exercise program) within a clinical trial.

OUTCOME MEASURES

Subjects were followed for 1 year via mailed questionnaires to assess levels of pain (Visual Analog Scale) and dysfunction (Roland Morris).

RESULTS

Study subjects had a decrease in pain and disability after intervention regardless of which group they attended (p < 0.002), however, during the year after care, subjects who received chiropractic care (flexion distraction therapy) had significantly lower pain scores than subjects who received physical therapy (exercise program) (p = 0.02).

CONCLUSIONS

In this first trial on flexion distraction care, flexion distraction was found to be more effective in reducing pain for 1 year when compared to a form of physical therapy.

Amount of health care and self-care following a randomized clinical trial comparing flexion-distraction with exercise program for chronic low back pain

Background

Previous clinical trials have assessed the percentage of participants who utilized further health care after a period of conservative care for low back pain, however no chiropractic clinical trial has determined the total amount of care during this time and any differences based on assigned treatment group. The objective of this clinical trial follow-up was to assess if there was a difference in the total number of office visits for low back pain over one year after a four week clinical trial of either a form of physical therapy (Exercise Program) or a form of chiropractic care (Flexion Distraction) for chronic low back pain.

Methods

In this randomized clinical trial follow up study, 195 participants were followed for one year after a four-week period of either a form of chiropractic care (FD) or a form of physical therapy (EP). Weekly structured telephone interview questions regarded visitation of various health care practitioners and the practice of self-care for low back pain.

Results

Participants in the physical therapy group demonstrated on average significantly more visits to any health care provider and to a general practitioner during the year after trial care (p < 0.05). No group differences were noted in the number of visits to a chiropractor or physical therapist. Self-care was initiated by nearly every participant in both groups.

Conclusion

During a one-year follow-up, participants previously randomized to physical therapy attended significantly more health care visits than those participants who received chiropractic care.

Changes in Blood Pressure After Various Forms of Therapeutic Massage: A Preliminary Study

OBJECTIVES

The objective of this study was to determine the change in blood pressure (BP) in normotensive and prehypertensive adults resulting from a therapeutic massage, and the factors associated with such changes, including demographic and massage characteristics.

DESIGN

SETTINGS/LOCATION

National University of Health Sciences Massage Therapy Clinic, Lombard, IL.

SUBJECTS

The subjects were 150 current adult massage therapy clients with BP lower than 150/95.

INTERVENTIONS

BP was measured before and after a therapeutic massage.

OUTCOME MEASURES

Change in BP and potential associated factors such as type of massage, duration of massage, specific body area massaged, amount of massage pressure, and demographic characteristics were studied.

RESULTS

Overall, systolic BP decreased by 1.8 mm Hg and diastolic BP increased by 0.1 mm Hg. Demographic factors associated with BP decrease included younger age (p = 0.01) and taller stature (p = 0.09). Type of massage was associated with change in BP: Swedish massage had the greatest effect at BP reduction. Trigger point therapy and sports massage both increased the systolic BP, and if both forms of massage were included in a session, both the systolic and diastolic BP readings significantly increased. No other massage factors were associated with a significant change in BP.

CONCLUSIONS

Type of massage was the main factor affecting change in BP. Increases in BP were noted for potentially painful massage techniques, including trigger point therapy.

A randomized clinical trial and subgroup analysis to compare flexion-distraction with active exercise for chronic low back pain

Many clinical trials on chiropractic management of low back pain have neglected to include specific forms of care. This study compared two well-defined treatment protocols. The objective was to compare the outcome of flexion-distraction (FD) procedures performed by chiropractors with an active trunk exercise protocol (ATEP) performed by physical therapists. A randomized clinical trial study design was used. Subjects, 18 years of age and older, with a primary complaint of low back pain (>3 months) were recruited. A 100 mm visual analogue scale (VAS) for perceived pain, the Roland Morris (RM) Questionnaire for low back function, and the SF-36 for overall health status served as primary outcome measures. Subjects were randomly allocated to receive either FD or ATEP. The FD intervention consisted of the application of flexion and traction applied to specific regions in the low back, with the aid of a specially designed manipulation table. The ATEP intervention included stabilizing and flexibility exercises, the use of modalities, and cardiovascular training. A total of 235 subjects met the inclusion/exclusion criteria and signed the informed consent. Of these, 123 were randomly allocated to FD and 112 to the ATEP. Study patients perceived significantly less pain and better function after intervention, regardless of which group they were allocated to (P<0.01). Subjects randomly allocated to the flexion-distraction group had significantly greater relief from pain than those allocated to the exercise program (P=0.01). Subgroup analysis indicated that subjects categorized as chronic, with moderate to severe symptoms, improved most with the flexion-distraction protocol. Subjects categorized with recurrent pain and moderate to severe symptoms improved most with the exercise program. Patients with radiculopathy did significantly better with FD. There were no significant differences between groups on the Roland Morris and SF-36 outcome measures. Overall, flexion-distraction provided more pain relief than active exercise; however, these results varied based on stratification of patients with and without radiculopathy and with and without recurrent symptoms. The subgroup analysis provides a possible explanation for contrasting results among randomized clinical trials of chronic low back pain treatments and these results also provide guidance for future work in the treatment of chronic low back pain.

Self-reported quality of life in users and nonusers of dietary supplements in cancer

GOALS OF WORK

To describe the Quality of Life (QoL) characteristics of users of dietary supplements vs nonusers.

PATIENTS AND METHODS

A survey of 225 cancer patients presenting for treatment at Cancer Treatment Centers of America was completed between November 2001 and October 2003. A validated instrument assessed the use of 56 dietary supplements in the past month. Two validated questionnaires assessed QoL. Mean QoL scores were compared between the users and nonusers using univariate and multivariate linear regression.

RESULTS

Of 225 patients, 91 (40%) were males and 134 (60%) females. Sixty seven (30%) had breast cancer, 40 (18%) colorectal cancer, and 32 (14%) lung cancer. One hundred sixty four (73%) had used dietary supplements in the past month, while 61 (27%) had not. Mean European Organization for Research Treatment of Cancer QoL scores were significantly better among the users for physical and emotional function scales and fatigue, nausea, appetite loss, and constipation symptom scales adjusting for tumor site. In the stratified analysis, lung cancer patients did not show any statistically significant differences in QoL scores between the users and nonusers. Colorectal cancer patients demonstrated statistically significant differences in constipation symptom, with dietary supplement users having better QoL. Breast cancer patients demonstrated statistically significant differences in several QoL scale scores between users and nonusers.

CONCLUSIONS

Contrary to some of the previously published research, this study, conducted at a community hospital comprehensive cancer center that combines alternative treatment approaches with conventional cancer care, found better self-reported QoL among the users of dietary supplements, as compared to nonusers. The next step in this research is to prospectively evaluate the patterns of changing QoL in relation to dietary supplement use across the entire duration of cancer diagnosis and treatment.

Recruitment and Accrual of Women in a Placebo-Controlled Clinical Pilot Study on Manual Therapy

OBJECTIVE

To investigate the accrual rates and recruitment processes among 3 Midwestern sites during a pilot study on manual therapy for chronic pelvic pain.

DESIGN

Multisite pilot study for a randomized, placebo-controlled clinical trial.

SETTING

Three chiropractic institutions in or near major metropolitan cities in the Midwestern United States.

SUBJECTS

Thirty-nine women aged 18 to 45 with chronic pelvic pain of at least 6 months duration, diagnosed by a board certified gynecologist.

MAIN OUTCOME MEASURES

The method of recruitment was collected for each individual who responded to an advertisement and completed an interviewer-administered telephone screen. Participants who were willing and eligible after 3 baseline visits were entered into a randomized clinical trial. The number of responses and accrual rates were determined for the overall study, each of the 3 treatment sites, and each of the 5 recruitment efforts.

RESULTS

In this study, 355 women were screened over the telephone and 39 were randomized, making the rate of randomization approximately 10%. The most effective recruitment methods leading to randomization were direct mail (38%) and radio advertisements (34%). However, success of the recruitment process differed by site.

CONCLUSIONS

Based on the accrual of this multisite pilot study, a full-scale trial would not be feasible using this study's parameters. However, useful information was gained on recruitment effectiveness, eligibility criteria, and screening protocols among the 3 metropolitan sites.

Research assistants' perspective of clinical trials: results of a focus group

OBJECTIVE

To better understand the experiences and problems encountered by research assistants (RAs) involved in clinical trials to improve the process of RA training for future studies.

DESIGN

A 1-time focus group of research assistants was conducted.

SETTING

A chiropractic college in the United States during a national chiropractic research agenda conference.

SUBJECTS

Eight research assistants from 2 teaching institutions, who are directly involved in clinical trials and have patient-centered responsibilities, such as recruiting patients, interviewing patients, and collecting data. Main outcome measures Responses to predetermined questions were qualitatively compiled. Question topics included research assistants' experiences while administering phone screens, questionnaires, and informed consents.

RESULTS

Research assistants involved in this focus group expressed they were adequately trained in telephone screening and administering informed consent but felt they required more training in administering self-report questionnaires to patients. The majority of problems they encountered were related to a lack of information. To improve training of future RAs, more detailed study information is necessary, such as how to describe study treatments and how to give questionnaire instructions.

CONCLUSIONS

The comparability of responses by the members of this focus group was interesting. Members had similar experiences within clinical trials and found that the problems encountered were common across studies.

Issues in planning a placebo-controlled trial of manual methods: results of a pilot study

OBJECTIVE

There are fundamental differences between the administration of medications and the application of manual procedures, such as those used by chiropractors. The objective of this study was to gather preliminary information on how to address these differences in the design of a multisite, randomized placebo-controlled trial of chiropractic care for women with chronic pelvic pain (CPP).

DESIGN

Pilot study for a multisite, randomized, placebo-controlled clinical trial.

SETTING

Three chiropractic research clinics in the midwest United States.

SUBJECTS

Thirty-nine (39) women with CPP of at least 6 months' duration, diagnosed by board-certified gynecologists.

INTERVENTIONS

The active intervention consisted of the chiropractic technique, lumbar spine flexion-distraction, combined with manual Trigger Point Therapy. The placebo intervention consisted of a sham chiropractic procedure performed with an instrument combined with effleurage (light massage).

OUTCOME MEASURES

The primary outcome measure was the change in the Pain Disability Index (PDI) from baseline to the end of treatment (6 weeks), assessed by group and site. If the change score was in the same direction at all sites, the results were to be combined to estimate treatment effect size.

RESULTS

Patient characteristics were similar to those of patients with CPP in other studies. Recruitment methods, particularly in respect to the eligibility criteria and screening protocols, would require modification in order to recruit an adequate sample for the planned randomized controlled trial. Clinicians followed standardized procedures with apparently minimal deviation, patients in both groups were satisfied with their care and blinding appeared to be successful. PDI change scores were not consistent across sites and so results were not combined and overall treatment effect sizes were not estimated.

CONCLUSIONS

The technical and personnel resources required to achieve adequate standardization of procedures at multiple sites may make a placebo-controlled trial unfeasible, given our current lack of knowledge about the active agent in manual chiropractic procedures.

Recruitment and accrual of women in a randomized controlled trial of spinal manipulation

OBJECTIVE

To report on recruitment efforts and accrual rates for a nonmusculoskeletal chiropractic clinical trial.

DESIGN

Information regarding the method of recruitment was collected for each individual who responded to an advertisement and completed an interviewer-administered telephone screening.

SETTING

A suburban chiropractic teaching clinic with recruitment efforts extending throughout the larger metropolitan area.

PATIENTS

A total of 2312 women were screened for participation and the advertisement source was noted for each. Of these, 138 women were recruited and fulfilled all study requirements.

MAIN OUTCOME MEASURES

The numbers of responses and accrual rates were determined for 8 different recruitment methods: newspaper advertisements, community referrals, radio advertisements, community colleges, press releases, a community electronic sign, public television, and local posters.

RESULTS

The most effective recruitment methods were newspaper advertisements, community referrals, and radio advertisements; the least effective methods were public television and local posters.

CONCLUSIONS

The effort required for the recruitment of subjects was underestimated in this study. Based on the information gained, future recruitment methods for study participants will primarily focus on low-effort, high-yield methods such as newspaper and radio advertising, followed by press releases, campus electronic signs, and public television.
