“…The Tampa Scale for Kinesiophobia (TSK) with a score range of 17-68 (low-high) was used to measure the patient's current painrelated fear of movement/(re)injury [45]. The Self-Efficacy Scale (SES) with a score range of 8-64 (low-high) was used to measure patient's belief in their ability to perform physical activities [11]. To investigate the patient's beliefs about the expected outcomes related to future low back pain, the Back Beliefs Questionnaire (BBQ) with a score range of 9-45 was used [37].…”

Prediction studies testing a thorough range of psychological variables in addition to demographic, workrelated and clinical variables are lacking in lumbar fusion surgery research. This prospective cohort study aimed at examining predictions of functional disability, back pain and health-related quality of life (HRQOL) 2-3 years after lumbar fusion by regressing nonlinear relations in a multivariate predictive model of pre-surgical variables. Before and 2-3 years after lumbar fusion surgery, patients completed measures investigating demographics, work-related variables, clinical variables, functional self-efficacy, outcome expectancy, fear of movement/(re)injury, mental health and pain coping. Categorical regression with optimal scaling transformation, elastic net regularization and bootstrapping were used to investigate predictor variables and address predictive model validity. The most parsimonious and stable subset of pre-surgical predictor variables explained 41.6, 36.0 and 25.6% of the variance in functional disability, back pain intensity and HRQOL 2-3 years after lumbar fusion. Pre-surgical control over pain significantly predicted functional disability and HRQOL. Pre-surgical catastrophizing and leg pain intensity significantly predicted functional disability and back pain while the pre-surgical straight leg raise significantly predicted back pain. Postoperative psychomotor therapy also significantly predicted functional disability while pre-surgical outcome expectations significantly predicted HRQOL. For the median dichotomised classification of functional disability, back pain intensity and HRQOL levels 2-3 years post-surgery, the discriminative ability of the prediction models was of good quality. The results demonstrate the importance of pre-surgical psychological factors, leg pain intensity, straight leg raise and postoperative psychomotor therapy in the predictions of functional disability, back pain and HRQOL-related outcomes.

“…Many tools are available to help evaluate personality and behavior in back pain patients. There have now been a few studies addressing the effect of these factors on functional testing [4,7,16]. Hirsch et al found that isoinertial performance was significantly worse among patients exhibiting excessive illness behavior as determined by Waddell scores [7,21].…”

“…Research into the relationships between lumbar dynamometry performaces and multiple demographic parameters has previously been performed using isokinetic devices [3,9]. However, any comparison of these results to results obtained using an isoinertial device is hampered by various differences between the two devices.…”

“…Some studies showed no relationship between height and force parameters [14,17], others found that age, height and weight are major factors in determining true isokinetic torque [9], again others found that of the parameters age, gender, body weight and height, only height showed positive and significant relationships with isokinetic torque parameters [3].…”

IntroductionInterest in developing isoinertial measurement techniques to evaluate the low back muscle function in patients with chronic low back pain has increased during the last few years. Patient performance is compared with standards estimated for healthy persons in order to gain insight into the low back muscle function. A problem inherent in muscle performance testing, however, is the large degree of intersubject variability. The absolute magnitude of force or velocity produced by individuals will vary according to different populations, depending on various factors, e.g. gender, age, weight and height. For example, the force exerted by a 60-year-old woman will be different from that expected for a 20-year-old man. The problem facing the clinician is interpretation of the obtained muscle performance. One way to handle this large intersubject variabilAbstract The purpose of this study was to investigate which demographic parameters are most important in relation to lumbar dynamometry performance in patients with chronic low back pain (LBP). Fortyfive chronic LBP patients participated in this study. Gender, age, weight and height were determined and a lumbar dynamometry measurement was carried out, using the Isostation B200. Student's t-test, ANOVA techniques and correlation coefficients were used to investigate the relationships between each demographic parameter and lumbar dynamometry performance. Stepwise multiple linear regression analyses were performed afterwards to determine which demographic parameters are most important in relation to lumbar dynamometry performance. Results indicate significant relationships (1) between gender, height, weight and all lumbar dynamometry parameters and (2) between age and three of the six isometric torque parameters. No significant relationship was found between age and maximum velocity parameters. Results of the stepwise multiple linear regression analyses show that the demographic parameters explain 27-47% of the variance in maximum isometric strength parameters and 19-25% of the variance in maximum velocity parameters. Gender is the most important demographic parameter, being related to nearly all maximum isometric torque parameters (percentage explained variance 6-37%) and height is the only important demographic parameter related to the velocity parameters (percentage explained variance 19-25%). Weight and age account for only a small amount of variance in lumbar dynamometry parameters (percentage explained variance 5-7%), meaning that these parameters are non-relevant predictors.
