The purpose of this study was to assess if chronic low back pain patients have impaired paraspinal muscle O2 turnover and endurance capacity as compared to healthy control subjects during dynamic exercise. Middle-aged healthy male subjects (n = 12, control) and male patients with chronic low back pain (n = 17, CLBP) participated in the study. L4–L5 level paraspinal muscle fatigue was objectively assessed during earlier validated 90 s dynamic back endurance test (spectral EMG, MPFslope). Also EMG amplitude (EMGamplitude) and initial MPF (MPFinitial) were assessed from the initial 5 s of the endurance contraction. Simultaneously near infrared spectroscopy (NIRS) was used for quantitative measurement of local L4–L5 paraspinal muscle O2 consumption. Subcutaneous tissue thickness (ATT) was measured from the EMG and NIRS recording sites. The results indicated that control and CLBP groups were compatible as regarding anthropometric variables, paraspinal muscle activation levels (EMGamplitude), initial MPF (MPFinitial) and ATT. When the ATT was used as a covariate in the ANOVA analysis, CLBP group did not show significantly greater paraspinal muscle fatigability (right MPFslope – 12.2 ± 10.7%/min, left right MPFslope – 12.6 ± 13.3%/min) or O2 consumption (right NIRSslope – 52.8 ± 79.6 μM/l/s) as compared to healthy controls (right MPFslope – 11.9 ± 7.6%/min, left MPFslope – 12.7 ± 8.6%/min, right NIRSslope – 53.7 ± 95.2 μM/l/s). As a conclusion, these CLBP male patients did not show any impaired rate of paraspinal muscle oxygen consumption or excessive paraspinal muscle fatigability during dynamic exercise as compared with healthy controls. Subcutaneous tissue thickness has a strong influence on the NIRS and EMG amplitude measurements and, if unchecked, it could result in the false interpretation of the results. 相似文献

This study assesses functional ability of Parkinson's disease (PD) patients by means of an objective movement analysis (the PLM-test) and three clinical tests. The correlation between the tests was also studied. The main object of this study was to detect and measure relevant disabilities in Parkinson's disease to obtain a clinical test battery.
