Yet normal lumbar coupling patterns and total range of motion of this movement have not been established in the literature. Normal values for lumbar segmental coupling on anterior-posterior lumbo-pelvic radiographs during trunk list might be important for an analysis of segmental instability since ...
These tools were employed in a clinical laboratory setting to evaluate the full active ROM of the cervical spines (ie, flexion/extension, lateral bending, and axial rotation) of 60 asymptomatic subjects (30 females and 30 males; age, 20 to 75 y) as well as to assess the functional ROM ...
In both the lifting and repositioning tasks, post hoc comparisons were computed using Bonferroni adjustment for multiple comparisons (p-values were adjusted). Cohen’s d was calculated based on the raw data. The effect magnitude was classified as trivial (d < 0.2), small (0.2 < d < 0.5),...
19 Postmenopausal women are more prone to osteoporosis, and NaF-PET has shown that the women who had osteoporotic T-values, versus osteopenic and normal levels, had lesser uptake in the lumbar spine.20 Quantification of bone turnover typically is accomplished using SUVs or, alternatively, using...
The peak stress of the internal fixation system in the TT–CBT group was significantly lower than the other three fixation methods in all five conditions except for extension, with a statistically significant difference between the CBT–TT and TT–CBT groups in the left rotation condition (P ...
In addition, the maximum FJF values of the intact model and TLIF model at the L2/3 segment (18.43 N vs. 18.52 N) and L3/4 segment (5.57 N vs. 5.68 N) were similar during lateral bending. During extension and axial rotation, the maximum FJF values in the TLIF model were 42.59 and ...
Mean values and standard deviation for these parameters in both the compensated and decompensated curves are summarized in Table 1. Table 1 Radiographic measurements Full size table High correlation was identified between C7 plumb line coronal deviation postoperatively and derotation of lumbar apical ...
Part 3: Preliminary data on isokinetic torso rotation testing with myoelectric spectral analysis in normal and low-back ... A prototype isokinetic torso rotation unit and an EMG signal processing system were utilized to obtain preliminary information on torso rotation. In Study ... TOM G. MAYER,...
The intersegmental rotation ranges in the three degenerative models are higher than in the normal model in flexion and extension. The values for the mild degeneration model in lateral bending and all the degeneration models in axial rotation are lower than in the normal model. The Tresca stresses...
An average conduction velocity of 50% below normal values was found in cauda equina roots of individuals with redundant nerve roots. Tsuji and colleagues (1985) believed that such neurologic changes were probably permanent. Ischemia during stenosis As mentioned, stenosis of the vertebral canal has ...
