Escola de coluna para pacientes com lombalgia: abordagem interdisciplinar

Escuela de columna para pacientes com dolor lumbar: enfoque interdisciplinario

Abstracts

OBJECTIVE:

To analyze and evaluate an interdisciplinary educational treatment - Spine School.

METHODS:

This study is a non-controlled clinical trial. Twenty one individuals (19 women) aged 27-74 years diagnosed with chronic low back pain were enrolled and followed-up by a rheumatologist and an orthopedist. The evaluations used were SF36, Roland Morris, canadian occupational performance measure (COPM) and visual analogue scale (VAS) of pain that were performed before and after seven weeks of treatment.

RESULTS:

We found statistically significant improvements in vitality (mean 48.10 vs. 81.25) p=0.009 and limitations caused by physical aspects (mean 48.81 vs. 81.25) p=0.038 and perception of pain (mean 6.88 vs. 5.38) p=0.005. Although the results were suggestive of improvement, there were no statistical significant differences in the domains social aspects (average 70.82 vs. 92.86) p=0.078, emotional aspects (average 52.38 vs. 88.95) p=0.078, and the performance satisfaction (mean 4.94 vs. 8.24) p=0.074.

CONCLUSION:

The Interdisciplinary Spine School was useful for improvement in some domains of quality of life of people with low back pain.

INTRODUCTION

On average, between 65% and 80% of the world's population develops low back pain at some point in their lives, generating high costs associated with the treatment of low back pain, and of patients with chronic pain. 1Borenstein DG. Epidemiology, etiology, diagnostic evaluation, and treatment of low back pain. Curr Opin Rheumatol. 2000;12(2):143-9.

Low back pain has multifactorial causes; it can be exacerbated by factors such as age, gender, and low income, and females are more affected.3Shiri R, Karppinen J, Leino-Arjas P, Solovieva S, Viikari-Juntura E. The association between obesity and low back pain: a meta-analysis. Am J Epidemiol. 2010 ;171(2):135-54.

Some treatments for low back pain focus only on the physical aspects of the illness, but with the steady increase in complaints from individuals, the creation of different methods and means of treatment became necessary. One of these methods was the creation of the Spine/Posture School.4Helfenstein Junior M, Goldenfum MA, Siena C. Occupational low back pain. Rev Assoc Med Bras. 2010;56(5):583-9.

The first Spine School emerged in 1969, in the Danbery Hospital in Sweden, and was called the Back School,5 an educational and training program for people diagnosed with chronic low back pain, focusing on its prevention and the promotion of spine health.

In Brazil, the first Back School, known as the "Escola de Postura" [Posture School], was introduced at the Hospital do Servidor Público Estadual de São Paulo6, São Paulo, SP, Brazil, in 1972.

Based on the diversity of populations, interventions, and comparison groups, there is insufficient information about the clinical effects of back schools,7van Middelkoop M, Rubinstein SM, Kuijpers T, Verhagen AP, Ostelo R, Koes BW, et al. A systematic review on the effectiveness of physical and rehabilitation interventions for chronic non-specific low back pain. Eur Spine J. 2011;20(1):19-39. because many schools presented divergent results; in the American school there is evidence of improvements in pain and disability, while in Brazil, the best results relate to pain, functionality, and social issues. 5Chung TM. Escola de Coluna: experiência do Hospital das Clínicas da Universidade de São Paulo. Acta Fisiátr. 1996;3(2):13-7.

Interdisciplinary follow-up enables the synthesis of knowledge from different scientific fields, and facilitates broader, biopsychosocial care. The Spine School therefore proposes this type of enhanced care.

This study evaluates the results obtained from the Interdisciplinary Spine School.

MATERIAL AND METHODS

This study was part of a university extension program, therefore no informed consent was signed. This was a non-controlled clinical trial. Twenty-one volunteers of both sexes, with symptomatic diagnoses of chronic low back pain, selected from an outpatient spine clinic, participated in The Spine School.

Volunteers with symptomatic diagnoses of non-specific chronic low back pain who were in regular medical follow-up were included in the study. Participants with cognitive deficits, determined by a score of less than 13 points in a mini mental state examination (MMSE), and who missed more than two treatment sessions, were excluded.

The volunteers were evaluated in relation the categories of pain, quality of life, function, and level of satisfaction with the treatment, at the beginning and at the end of the program. Meetings took place once a week, for one hour, over a total of seven weeks.

The evaluation tools used were:

  1. Mini mental state examination (MMSE): this is a clinical assessment of changes in cognitive state (a process involving attention, perception, memory, reasoning, judgment, imagination, thinking, and language). The test attempts to evaluate temporal and spatial orientation, immediate memory, attention and calculation, evocation, language, and praxis,8 and is validated for Brazil,9Bertolucci PH, Brucki SM, Campacci SR, Juliano Y. The Mini-Mental State Examination in a general population: impact of educational status. Arq Neuropsiquiatr. 1994;52(1):1-7 with the following cutoff scores: Illiterate: 13 points; Did not complete elementary school (years 1 to 8): 18 points; Completed elementary school or higher (8 or more years): 26 points. The maximum score is 30 points.

  2. Visual analog scale for pain (VAS): assessment of pain at rest and in motion, varying from 0 (zero) for no pain to 10 (ten) for unbearable pain.1010 Huskisson EC, Jones J, Scott PJ. Application of visual-analogue scales to the measurement of functional capacity. Rheumatol Rehabil. 1976;15(3):185-7.

  3. SF-36 (The Short Form Health Survey): assessment of the quality of life, validated in Portuguese in 1999, consisting of eight sections: functional capacity, limitations from physical aspects, pain, general state of health, vitality, social aspects, emotional aspects, and mental health ranging from 0 (zero) to 100 (a hundred). The higher the score, the better the quality of life.1111 Ciconelli RM, Ferraz MB, Santos WS, Meinão IM, Quaresma MR. Tradução para a língua portuguesa e validação do questionário genérico de avaliação de qualidade de vida SF36 (Brasil SF36). Rev Bras Reumatol. 1999;39(3):143-50.

  4. Roland Morris, a questionnaire of 24 questions to evaluate the disability of patients with low back pain, translated into and validated for Portuguese.1212 Nusbaum L, Natour J, Ferraz MB, Goldenberg J. Translation, adaptation and validation of the Roland-Morris questionnaire--Brazil Roland-Morris. Braz J Med Biol Res. 2001;34(2):203-10.

  5. COPM (Canadian Occupational Performance Measurement) tool, capable of measuring the impact of an intervention of an individual and thus to detect changes in the client's self-perception in terms of their occupational performance and long term satisfaction, validated for Portuguese.1313 Magalhães C, Magalhães LV, Cardoso AA. Medida canadense do desempenho ocupacional - COPM. Versão Traduzida e validada. Belo Horizonte: Editora UFMG.; 2009. First, patients must list the five activities that they find most difficult to perform on a day-to-day basis, and then score them from zero to ten, considering their performance and their satisfaction with the final results of the task. The score ranges from 0 to 10, with a higher score indicated better performance ability.

  6. The meetings/classes took place as follows: 1) Initial evaluation to assess demographic data, application of MMSE, VAS, SF-36,

Roland Morris, and COPM tools and anatomy classes; 3) Class on diseases of the spine; 4) Types and the importance of medical diagnosis and treatment; 5) Physical exercises to strengthen the abdominal musculature, for lumbar stretching, and breathing control; 6) Theoretical and practical orientation on joint protection in performing daily activities, with the use adaptations to furniture and household utensils, where necessary; and 7) Nutritional counseling.

The data were expressed as averages and standard deviations. The Student-t test was used to compare the results obtained in the evaluation and reevaluation.

RESULTS

Twenty-one volunteers took part in the program, ranging from 27 to 74 years of age (average of 57.611 years of age). (Table 1)

Table 1.
Characteristic of the study population by sex and average age.

In our study, we observed that the initial and final evaluations showed significant improvements in vitality, limitations from physical aspects, and pain intensity, demonstrating that the theoretical and practical classes in postural counseling, environmental adaptations, and strengthening, stretching, and relaxation exercises achieved the desired outcomes in terms of awareness and changes to some daily activities. The SF-36 results suggested improvements in the domains of social aspects, emotional aspects, and satisfaction with performance, but without significant differences. (Table 2)

Table 2.
Results obtained from the SF-36 quality of life, Roland Morris, and COPM (Canadian Occupational Performance Measurement) questionnaires.

We obtained statistically significant differences in vitality (average 48.10 vs. 81.25, p=0.009), in limitations from physical aspects (average 48.81 vs. 81.25, p=0.038), and in the perception of pain (average 6.88 vs. 5.38, p=0.005), and while the results suggested an improvement, there were no statistically significant differences in the domains of social aspects (average 70.82 vs. 92.86, p=0.078), emotional aspects (average 52.38 vs. 88.95, p=0.078, or satisfaction with performance (average 4.94 vs. 8.24, p=0.074).

DISCUSSION

Our study showed that patients with chronic low back pain who participated in the spine school follow-up achieved improvements through a reduced perception of pain and in some areas of the quality of life questionnaire, such as vitality and limitations from physical aspects, with the suggestion of improvement in emotional and social aspects and satisfaction with occupational performance.

The inter/multidisciplinary interventions for the treatment and physical rehabilitation of chronic low back pain showed promising results,7van Middelkoop M, Rubinstein SM, Kuijpers T, Verhagen AP, Ostelo R, Koes BW, et al. A systematic review on the effectiveness of physical and rehabilitation interventions for chronic non-specific low back pain. Eur Spine J. 2011;20(1):19-39. because, as an approach which combines various types of knowledge, it favors integrated care of the patient's health.

Unlike Van Middelkoop et al,7 who state that they did not find statistically significant short term improvements in their studies, our program produced good results over a short period of time, which may be explained by the low number of participants in the classes, favoring total attention to each participant, the presence of different professionals running the classes, and the approach that was focused on the interests of each participant.

According to Chung, 5 the Spine School program is efficient, mainly in making the patient aware that he is the key agent for promoting his own health, and because it is a multi/interdisciplinary program that provides different perspectives on the same problem by different health professionals, with the aim of improving the participant's overall health.

With the use of the Canadian Occupational Performance Measurement (COPM), although no significant statistically significant differences were observed, an improvement in the participants is indicated, as changes in self-perception, occupational performance, and satisfaction were observed during their participation in our educational program.

The SF-36 assessment of the quality of life suggests that the interdisciplinary Spine School positively influenced the lives of the volunteers who, although still living with the disease, looked for ways to improve their physical, emotional, psychological, and social health.

The rate of Spine School educational program participant dropouts is widely reported in the literature,1414 Tsukimoto G.R. Avaliação longitudinal da escola de postura para dor lombar crônica através da aplicação dos questionários Roland-Morrise Short Form Health Survey (SF36) [dissertação]. São Paulo: Faculdade de Medicina, Universidade de São Paulo; 2006. making constant redesign of these treatments necessary. In our program we tried to be as flexible as possible and to adapt class schedules to accommodate the demands of the volunteers.

The first limitation of our study is the number of volunteers. There was a high dropout rate over the seven-week class period, indicating the need to rethink the form of patient contact, seeking to adapt class schedules to better accommodate their availability, since our Interdisciplinary Spine School program is the only one in the region.

Many of the participants in our program are from other municipalities and have low incomes, which can make access to the location where classes were held more difficult. Often, patients had to miss work or travel long distances.

We understand the importance of following the CONSORT guidelines for clinical trials, but because this research was part of a pioneer project in the region, we had difficulty selecting volunteers. For this reason, we opted not to use a control group, or any of the other items required for stricter methodological control.

More research is needed on the efficacy of spine schools, 1515 Brox JI, Storheim K, Grotle M, Tveito TH, Indahl A, Eriksen HR. Systematic review of back schools, brief education, and fear-avoidance training for chronic low back pain. Spine J. 2008;8(6):948-58. because many of the findings in the literature are conflicting, and present little evidence of their effectiveness, generating doubts as to the effectiveness of this type of treatment. In future research, the number of participants should be increased and a control group included to enable a controlled and randomized clinical trial to be conducted.

CONCLUSION

We conclude that in this Interdisciplinary Spine School, we obtained significant improvement in the perception of pain and in the areas vitality and physical aspects, and an indication of improvement in the emotional and social aspects and satisfaction with performance in patients with chronic non-specific low back pain.
