OBJECTIVE: The objective of this study was to develop and validate a questionnaire on specific knowledge about low back pain entitled "The Low Back Pain Knowledge Questionnaire". INTRODUCTION: There is a need for instruments to assess patient knowledge regarding chronic illness. Such methods can contribute to the education of patients. METHODS: The Low Back Pain Knowledge Questionnaire was developed through five focus groups. The questionnaire was distributed to 50 patients to assess their comprehension of the terms. To assess the reproducibility, 20 patients were surveyed by two different interviewers on the same day and twice by a single interviewer with a one-to-two week interval. For the construct validation, the Low Back Pain Knowledge Questionnaire was given to 20 healthcare professionals with knowledge on low back pain and 20 patients to determine whether the questionnaire would discriminate between the two different populations. To assess the sensitivity of the questionnaire to changes in the knowledge level of the patients, it was given to 60 patients who were randomly assigned to the Intervention Group and the Control Group. The Intervention Group answered the questionnaire both before and after attending a chronic back pain educational program (back school), whereas the Control Group answered the questionnaire twice with an interval of one month and no educational intervention. RESULTS: The focus groups generated a questionnaire with 16 items. The Spearman's correlation coefficient and the intra-class correlation coefficients ranged from 0.61 to 0.95 in the assessments of the intra-observer and inter-observer reproducibility (p < 0.01). In the construct validation, the healthcare professionals and patients showed statistically different scores (p < 0.001). In the phase regarding the sensitivity to change, the Intervention Group exhibited a significant increase in their specific knowledge over the Control Group (p < 0.001). CONCLUSION: The Low Back Pain Knowledge Questionnaire was validated and proved to be reproducible, valid and sensitive to changes in patient knowledge.

The purpose of this study was to determine if ratings of discomfort differ over time between two ergonomic chairs of the same approximate cost. Twenty participants from a metropolitan university sat on two types of ergonomic chairs for 90~minutes in each of two sessions while performing typing, reading, and writing tasks. Repeated measures three-way and two-way analyses of variance were used to examine the effect of the ergonomic chair design on rating of discomfort. Data were collected using the General Comfort Rating Scale (GCRS) and the Body Part Discomfort Rating Scale (BPDRS), which were a dministered at 0, 30, 60, and 90 minute marks of each session. The results revealed: 1) discomfort was not related to the type of chair, 2) discomfort increased over time, 3) discomfort was influenced by the task performed while sitting, 4) discomfort level decreased when switching between different chairs, and 5) most discomfort was reported in the low back and lower arms.

AIM: The aim of this study was to translate the questionnaire into Turkish and to investigate the test-retest reliability, construct validity and its sensitivity to change following physical therapy. METHODS:The questionnaire was translated into Turkish using the forward and backward translation technique. Test-retest reliability was assessed with the correlation coefficients. Scale analysis for internal validity, the Cronbach's alpha score was calculated. Construct validity was tested with principal components analysis and was also tested with divergent validity. Following three weeks of treatment, sensitivity to change and responsiveness of the questionnaire was assessed. RESULTS: The questionnaire was applied on 55 patients and high correlations were found on the repeated items 48 hours later. In the scale analysis, the Cronbach's alpha score was found as 0.911 for the total questionnaire. Two factors were found compatible with the original questionnaire with principal components analysis. These two factors explain 61.647% of the total variance in the questionnaire performed on 150 patients. In divergent validity, the fear avoidance beliefs were found in low correlation with the clinical variables. Sensitivity to change and responsiveness of the FABQ was found to be low. CONCLUSIONS: FABQ has sufficient psychometric features for its applicability in the Turkish population with subacute and chronic low back pain.

OBJECTIVE: To investigate a method of auricular reconstruction with overlapping tissue expansion techniques and without skin graft. METHODS: Two tissue expanders were implanted subcutaneously at the mastoid. 6 patients with microtia (overlapping group) were treated. After completion of skin expansion, the expanders were removed. The autologous rib cartilage or Medpor scaffolds were implanted. The flap A made by the upper expanded flap was used to cover the upper part of the front and the back of the framework. The flap B made by lower expanded flap was transplanted to cover the lower part of the back of frameworks. The remaining expanded skin was designed to cover the postauricular wound. The other thirteen microtia patients who treated by the traditional auricular reconstruction were selected as control(traditional group). RESULTS: Skin graft was not necessary in the patients of overlapping groups. The appearance of the reconstructed ear was very satisfactory. Epidermal necrosis of 0.5 cm x 0.5 cm happened at the distal end of postauricular flap in one case. All the other cases had no complication of infection or framework exposure. The patients were followed up for 3-6 months. Compared with the traditional group, the scar in the costal donor site was inconspicuous in overlapping group (P < 0.05). The complication rate was lower and satisfactory rate was higher in overlapping group (P < 0.01 and P < 0.05). But there was hair growth in the helix of reconstructed ear in overlapping group. CONCLUSIONS: The overlapping expansion can provide enough skin for ear reconstruction. The skin graft is not necessary, resulting less donor site scar and low complications.

The aim of this study was to analyse whether Physical Activity Index (PAI), Physical Fitness, Screen Time (watching TV and computer use), Socio-economic Status and Commuting to School made a significant contribution to longitudinal changes in Body Mass Index (BMI) in youth. This longitudinal study was carried out over a period of 3 years with 345 students (147 boys) who were between 11 and 16 years old at the beginning of the study. Students were invited to perform tests from FITNESSGRAM Battery for Curl-Ups, Push-Ups, Back-Saver Sit and Reach, and 20 m Shuttle-Run (CRF). Fitness tests were categorized in "Healthy Zone" (HZ) and "Under Healthy Zone" (UHZ), PAI in "less active" and "active"; Socio-economic Status, in low, middle and high education level, and Commuting in active and passive. BMI was corrected for age and gender meaning that we subtracted the age-and-sex-specific cut points for overweight. Corrected body mass index was used as dependent variable in a Linear Mixed Model. The main result was the strong positive and independent association of individuals with CRF performances UHZ with corrected body mass index. In conclusion, the results of this longitudinal study showed markedly an important relationship of lower fitness levels with the risk of being overweight/obese, in particular CRF and abdominal strength.

OBJECTIVES: To investigate whether patients with chronic low back pain (CLBP) show "guarded" movements during walking. It is hypothesized that guarding will be reflected by increased lumbar muscle activity during all periods of stride and secondary, relatively lesser relaxation during periods of swing compared with double support. Furthermore, it is hypothesized that higher levels of perceived fear and disability are related to increased muscle activity and less relative relaxation. MATERIALS AND METHODS: In a cross-sectional study 63 patients with CLBP and 33 healthy controls walked on a treadmill at 3.8 km/h. Surface electromyography (sEMG) data of the erector spinae were obtained and smoothed rectified sEMG (SRE) values were calculated per period of swing and double support. The ratio of SRE values in swing to double support was used as a measure of relative relaxation (SRE ratio). In addition, the relationship between SRE values, the Roland Morris Disability Questionnaire, and the Tampa Scale for Kinesiophobia was analyzed in patients with CLBP. RESULTS: Mean SRE values were significantly higher in patients with CLBP than in controls both during periods of double support and swing. SRE ratios were not significantly different between groups. Results showed no influence of disability or fear of movement on either SRE values or ratios. DISCUSSION: In patients with CLBP, increased lumbar muscle activity during all periods of stride, with comparable alteration between swing and double support, suggests difficulties with total muscle relaxation. On the basis of this evaluation, it is concluded that patients with CLBP show a guarding mechanism during walking. No relationship is found between perceived fear, disability, and muscle activity.

OBJECTIVE: The purpose of this study was to evaluate the health impact of working conditions at the Ruashi mine in the Katanga Province in the Democratic Republic of Congo. MATERIALS AND METHODS: A cross-sectional etiological study was conducted in two cohorts including 100 miners and 109 students. Data necessary to allow comparison disease symptoms in the two cohorts were collected using a questionnaire. Odds ratios (OR) and 95% confidence intervals (95% CI) were estimated. A secondary analysis was performed to compare different mine workstations, i.e., diggers (n=61) versus non-diggers (n=39). Two logistical regression models were used to estimate adjusted OR and 95% CI for the association be tween occupation/workstation and disease symptoms. RESULTS: In comparison with students, miners exhibited higher frequencies for all symptoms even after adjustment. The highest ORs were observed for musculoskeletal disorders, i.e., low back pain (OR=36.5) and upper (OR = 20.7) or lower (OR = 18.3)] extremity pain. They were followed by respiratory disorders (OR = 5.91) and headache (OR = 5.34). CONCLUSION: The high exposure frequencies and OR's observed in this study underline the negative health impact of mine working conditions. Further occupational study will be needed to obtain and compare more data.

BACKGROUND AND OBJECTIVE: Studies on back extensor endurance in adolescents are scarce. This study sought to establish reference data and pattern of back extensor endurance in school-aged adolescents with and without low-back pain (LBP) from Nigeria. SUBJECTS AND METHODS: This study recruited 625 adolescents aged 11 to 19 years from eight randomly selected secondary schools. The modified Biering-S ørensen test of Static Muscular Endurance (BSME) was used to assess isometric endurance of the back extensors. Demographic and anthropometric data were collected. A modified LBP questionnaire was used to assess the presence of LBP. Descriptive and inferential analyses were used to analyze data. Sig nificance was set at 0.05 alpha-level. RESULTS: The mean isometric holding time (IHT) of all the participants was 132.9 $\pm$ 65.6. Males had significantly higher significant (p=0.026) IHT than females. Adolescents without LBP had a higher significant IHT (p=0.042) than those with reported history o f previous LBP and those with present LBP (p=0.000) respectively. Using percentile values, poor endurance was defined as IHT that is < 90.0 s and < 67 s for males and females respectively; medium endurance was defined as IHT that ranged between 90 and 193 s and 67 and 170 s for males and females respectively while good endurance was defined as IHT that is > 193 s and > 170 s for males and females respectively. IHT was significantly related to each of body mass index, hip circumference and waist-to-hip ratio (p < 0.05). CONCLUSION: Isometric back extensors endurance in Nigerian adolescents was comparable to the original Biering-S ørensen mean value. Majority of the participants had medium endurance performance with the back endurance pattern in the ratio 1:2:1. Male had higher isometric back extensors endurance than females. Decreased isometric back extensors endurance was associated with the presence of LBP in adolescents.

OBJECTIVE: The treatment of thoracolumbar burst fracture is a controversial issue. Although spinal fusion has been a touchstone of spinal fixation, nonfusion technique have become raising its popularity recently. Some studies suggested that nonfusion had several advantages over fusion. The aim of this prospective study was to compare long segment posterior instrumentation with fusion versus long-segment posterior instrumentation without fusion. METHODS: For this purpose, 42 consecutive patients were assigned to two groups. Group 1 included 21 patients treated by long segment instrumentation with fusion (WF), whereas Group 2 included 21 patients treated by long segment instrumentation without fusion (WOF). Long segment instrumentation was hook fixation (claw hooks attached to second upper vertebra and infralaminar hooks attached to first upper vertebra) above and pedicle fixation (pedicle screws attached to first and second lower vertebrae) below the fractured vertebra. RESULTS: Measurements of local kyphosis, sagittal index and anterior vertebral height compression showed that both group had similar outcome at final follow-up. Moreover, there was no difference between the two groups according to low back outcome score. Also, implant failure rate (4.7%) was quite low in both groups. However, WF group had prolonged operative time, increased blood loss and donor site morbidity. CONCLUSIONS: Radiological and clinical parameters demonstrated that spinal fusion is not necessary in long segment posterior instrumentation for the management of thoracolumbar burst fractures.

[Medline ID - 20023336]

OBJECTIVE: The study describes the clinical spectrum of patients with low back pain due to sacroiliac joint (SIJ) involvement with the proposition of a diagnostic scheme. METHODS: In this retrospective review, 61 patients with SIJ pain (unilateral or bilateral) greater than six weeks duration were evaluated by pain history, clinical examination including SIJ provocative tests, laboratory investigations and skeletal imaging. RESULTS: Fifty two patients (M: F, 31:21) were diagnosed to have specific SIJ pathologies amongst 61 patients presenting between 2002 to 2004. Forty patients (65%) were diagnosed with rheumatic conditions - ankylosing spondylitis (AS) - 21, undifferentiated spondyloarthropathy (UspA) - 11, psoriatic arthropathy (PS) - 5, reactive arthropathy (ReA) - 1 and juvenile spondyloarthropathy (JS)-2. Non rheumatic conditions were involved in 12 patients (20%) - osteitis condensus ilii (OCI) - 4, osteomalacia - 2, tuberculosis - 2, pyogenic arthritis - 1, pregnancy related sacroiliac joint pain - 2 and malignancy in 1 patient. The diagnosis could not be confirmed in 9 patients (15%). CONCLUSIONS: Medical history, clinical examination including SIJ tests, plain radiography and laboratory investigations were helpful in diagnosing SIJ pathology in 39% cases (n = 24), 46% (n = 28) needed CT or MRI. A diagnostic scheme of dividing the SIJ pathologies into rheumatic and non-rheumatic conditions was helpful in evaluating patients with suspected SIJ pathologies.
