“…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].…”

“…This scale asks patients to rate their pain on a scale from 0 to 10 by marking an "X" on a 10-centimeter horizontal line, hashed at two-point intervals, with Assessment of Opioid Misuse 11 higher numbers reflecting greater pain [23,33]. A pain rating is derived by rounding up to the next whole number subsequent to the hash mark.…”

This study comprised the first step in the psychometric development of a self-report screening instrument for risk of opioid medication misuse among chronic pain patients. A 26-item instrument, the Pain Medication Questionnaire (PMQ), was constructed based on suspected behavioral correlates of opioid medication misuse, which heretofore have received limited empirical investigation. The PMQ was administered to 184 patients at an interdisciplinary pain treatment center. Reliability coefficients for the PMQ were found to be of moderate but acceptable strength. Construct and concurrent validity were examined through correlation of PMQ scores to measures of substance abuse, physical and psychological functioning, and physicians' risk assessments. To explore high and low cutoff points for misuse risk, subgroups were formed according to the upper and lower thirds of PMQ scores and compared on validity measures. Higher PMQ scores were associated with history of substance abuse, higher levels of psychosocial distress, and poorer functioning. Future psychometric analyses will consider predictive validity and examine shortened versions of the instrument.

“…7,48 Moreover, isokinetic strength correlates significantly with functionality scores in gonarthrosis and patients with low back pain. 24,42 However, reference data of isokinetic peak force of the thigh and trunk have not, to our knowledge, been reported for individuals who are obese. Several methodological problems arise when testing those patients isokinetically (ie, appropriate fixation of the trunk, weighing of the trunk to perform gravity correction, 35 the inertia effects of the body when testing at high velocities, 6,18 pain inhibition due to osteoarthritis, 26 and cardiovascular problems 40 ).…”

“…21 Consequently, pain and loss of functionality could lead to loss of muscle strength. 42,48 A valid method to assess leg and trunk muscle strength is to measure peak joint torque using an isokinetic dynamometer. Although limitations exist for the individual patient, 25,28 isokinetic testing of knee and trunk muscle strength have proved to be sensitive and reliable measurements.…”

Study design:Cross-sectional study of isokinetic trunk and knee muscle strength in women who are obese. Objective: To provide reference values, to identify variables that affect peripheral muscle strength, and to provide recommendations for isokinetic testing of trunk and knee muscles in women who are obese and morbidly obese. Background: The assessment of peripheral muscle strength is useful for the quantification of possible loss of strength, for exercise prescription, and for the evaluation of the effect of training programs in obese individuals. Methods and Measures: Isokinetic trunk and leg muscle strength was assessed in 241 women who were obese (18-65 years, body mass index (BMI) Ն 30 kg/m 2 ). Trunk flexion and extension peak torque (PT) was measured using the Cybex TEF dynamometer; trunk rotation (TR) PT was measured using the Cybex TORSO dynamometer; and knee flexion/extension (KFE) PT was measured using the Cybex 350 dynamometer. Body composition was assessed using the bioelectrical impedance method; physical activity was assessed using the Baecke questionnaire; and peak VO 2 was assessed using an incremental exercise capacity test on a bicycle ergometer. To identify variables related to muscle strength, Pearson correlations were computed and a stepwise multiple regression analysis was performed. Results: Pearson correlation coefficients of all strength measurements at 60°/s revealed low-to-moderate negative associations with age and positive associations with mass, height, fat free mass (FFM), and peak VO 2 (P Ͻ 0.05), except for gravity-uncorrected trunk extension strength, which was not related to mass. The sports index of the Baecke questionnaire was associated with TR PT (r = 0.20, P Ͻ 0.01) and KFE PT (r = 0.18, P Ͻ 0.05). Conclusion:The weight of the trunk accounts largely for the measured trunk extensor and flexor strength in women who are obese. Contributing variables of isokinetic trunk flexion and extension strength in women who are obese are age, height, and FFM; whereas sports activities and aerobic fitness are contributing factors for trunk rotational and knee extension strength. Recommendations for measuring isokinetic muscle strength in individuals who are obese are provided.
