The aim of this cross-sectional study was to compare data on the level of aerobic capacity and body composition of nonspecific chronic low back pain (CLBP) patients with normative data matched for sex, age and level of sporting activity. The study population consisted of 101 outpatients with nonspecific CLBP who had entered a rehabilitation programme. Results were as follows: the mean (standard deviation) aerobic capacity (VO2max) of CLBP patients was significantly (P<0.001) lower 7.3 (5.6) ml/kg lean body mass/min as compared with the normative data. The mean (standard deviation) body fat percentage of the patients was significantly (P<0.001) higher 3.9 % (5.9) as compared with the normative data. These results provide evidence of a reduced level of aerobic capacity and an increased body fat percentage in nonspecific CLBP patients compared with healthy participants.
BACKGROUND: The predictive validity of the Low Back Pain Perception Scale is determined in two studies in general practice and showed sufficient discriminative ability, although the psychometric properties of the scale have never been established until now.OBJECTIVE: To determine the reliability and validity of the Low Back Pain Perception Scale in acute nonspecific low back pain patients.METHODS: The Low Back Pain Perception Scale has been authorized translated into Dutch by two bilingual content experts. A sample of 84 acute low back pain patients in physiotherapy primary care, mean age (SD) age 42 (12) years participated in this study. Internal reliability and a test-retest procedure within one-week interval were evaluated.RESULTS: The internal consistency Cronbach α=0.38 (95% CI 0.09 to 0.56) and test - retest reliability within one week Intra Class Correlation coefficient=0.50 (95% CI 0.31 to 0.64). Minimal Detectable Change was measured 1.95. The concurrent validity demonstrates Pearson's r=0.35 (95% CI 0.14 to 0.53).CONCLUSIONS:The Low Back Pain Perception Scale demonstrates poor internal consistency and reliability and moderate concurrent validity. Extreme high or low scores may be clinical relevant therefore the scale can be used as a first screening instrument.

OBJECTIVE:To develop a blended physiotherapeutic intervention for patients with non-specific low back pain (e-Exercise LBP) and evaluate its proof of concept.DESIGN:Focus groups with patients, physiotherapists, and eHealth and LBP experts were conducted to investigate values according to the development of e-Exercise LBP. Proof of concept was evaluated in a multicentre study.SETTING:Dutch primary care physiotherapy practices (n=21 therapists).PARTICIPANTS:Adults with non-specific LBP (n=41).INTERVENTION:e-Exercise LBP was developed based on clinical LBP guidelines and the focus groups, using the Center for eHealth Research Roadmap. Face-to-face physiotherapy sessions were integrated with a web application consisting of 12 information lessons, video-supported exercises and a physical activity module with the option to gradually increase individuals' level of physical activity. The intervention could be tailored to patients' risk of persistent disabling LBP, according to the STarT Back Screening Tool.MAIN OUTCOME MEASURES:Functional disability, pain, physical activity, sedentary behaviour and fear-avoidance beliefs, measured at baseline and 12 weeks.RESULTS:After 12 weeks, improvements were found in functional disability [Quebec Back Pain Disability Scale: mean difference (MD) -12.2/100; 95% confidence interval (CI) 8.3 to 16.1], pain (Numeric Pain Rating Scale: MD -2.8/10; 95% CI 2.1 to 3.6), subjective physical activity (Short Questionnaire to Assess Health Enhancing Physical Activity: MD 11.5minutes/day; 95% CI -47.8 to 24.8) and objective sedentary behaviour (ActiGraph: MD -23.0minutes/day; 95% CI -8.9 to 55.0). Small improvements were found in objective physical activity and fear-avoidance beliefs. The option to gradually increase physical activity was activated for six patients (15%). On average, patients received seven face-to-face sessions alongside the web application.CONCLUSIONS:The results of this study provide the first indication of the effectiveness of e-Exercise LBP, particularly for disability and pain among patients with LBP. Future studies will focus on end-user experiences and (cost-) effectiveness.KEYWORDS:Low back pain; Physiotherapy; Telemedicine; e-Health
