Showing papers in "Clinical Biomechanics in 1995"

TL;DR: This paper deals with methodological problems related to the reconstruction of the position and orientation of the human pelvis and the lower limb bones in space during the execution of locomotion and physical exercises using a stereophotogrammetric system.

TL;DR: The simple static back endurance test might have value in health examinations because of its strong predictive value of future low-back pain.

TL;DR: The discussion suggests that mechanical fatigue damage may frequently be the underlying cause of low back pain, even when degenerative changes are evident in the tissues, and the review ends by suggesting some priority areas for future research.

TL;DR: Dynamization of externally fixed diaphyseal fractures could improve bone healing in comparison to rigid fixation of fractures having similar remaining gap sizes by showing significantly greater callus formation and 45% greater tensile strength in the cortical osteotomy gap.

TL;DR: Comparisons were made between downhill and level walking in order to appreciate more fully the increased loadings on the lower extremity under more stressful but not atypical conditions.

TL;DR: The results of this study indicate that advanced computer-assisted techniques may significantly improve the accuracy and safety of surgical interventions of the spine and may in future be adapted to other applications in orthopaedic surgery.

TL;DR: This paper presents an algorithm for coordinate reconstruction and distortion correction using a modified polynomial method that was used for the measurement of patellar tendon moment arm, tibial plateau-tibial axis angle and patellAR tendon-tibia axis angle during knee extension using videofluoroscopy in vivo.

TL;DR: It was showed that fitness classes for pregnant women designed according to Canadian guidelines had no detectable effect on back pain during pregnancy, and design of fitness programmes for pregnantWomen should be reconsidered.

TL;DR: It was demonstrated that pronation modifications can affect the magnitude of the impact experienced by the body during locomotion and care should be exercised when orthotics that will be used for both walking and running are prescribed.

TL;DR: Using a three-dimensional stereophotogrammetric method, the motion in the joints of healthy men and women between 20 and 50 years of age was investigated with change in posture from the upright standing position, finding no statistically significant differences with respect to sex, age, or parturition.

TL;DR: The results demonstrated an average of 22% decrease in the median frequencies of the muscles sampled following resistive exercise, suggesting a state of local muscle fatigue and a selective decrease in scapulothoracic motion about two of the three scapular axes.

TL;DR: It was showed that fitness classes for pregnant women designed according to Canadian guidelines had no detectable effect on posture during pregnancy.

TL;DR: The results showed significant and substantial changes in pressure in selected areas for changes in sensory input, which increased in the midfoot area and decreased in the toe area with increasing sensory inputs.

TL;DR: A human cadaver model is presented to analyse tensile force distribution on the Median nerve and can be an aid to evaluate the specificity of a clinical provocation test for the median nerve.

TL;DR: Analysis and interpretation of shoulder muscle dysfunction, and implementation of conditioning protocols, require the availability of normative values pertaining to the common modes of contraction and relative to an acceptable and velocity setup, and this study provides a representative data base of normal subjects which may serve for these purposes.

TL;DR: This study supports the suggestion that some complications can be related to the mechanical behaviour of the fixator and can be considered as different types of fixators.

TL;DR: In this article, the relationship between the glenohumoral and scapulothoracic components of the motion was determined and the influence of the abduction speed and of the external load on it were investigated.

TL;DR: Changes in kinematics as a function of lifting weight and frequency was investigated in sagittal symmetric repetitive lifting, suggesting that quadriceps muscle strength is the limiting factor in repetitive squat lifting.

TL;DR: Quantifying the amount of strain experienced by the plantar aponeurosis is needed to identify how effective foot orthoses are in providing support to the foot's longitudinal arches and the described method will be useful to bioengineers concerned with the arch support component of running shoes.

TL;DR: The present study gains clinical significance by the studies showing relatively small oblique abdominal muscle strength in patients with low back pain, because a soft seat may be helpful in treatment and prevention, because it substitutes oblique abdomen muscle activity.

TL;DR: The results of this study show that 2-D analysis can be used to measure rearfoot motion accurately and therefore is feasible for use in the clinic.

TL;DR: The results indicate that the forces developed during maximal isokinetic knee extension are significantly reduced relative to other powerful dynamic activities but are higher than joint forces during simple walking and cycling activities.

TL;DR: The results of this study, in which the mechanical properties of the anterior cruciate ligament have been measured with force exerted anteriorly on the tibia, allow a more complete understanding of the mechanical behaviour of the posterior cruciates ligament and provide design data for anterior Cruciateligament grafts and prostheses.

TL;DR: The data presented in this study document that isokinetic lift, psychophysical lift, and static back endurance tests appear to measure very different aspects of muscle function, and comparing studies using these different test methods should be approached with these low inter-test correlations in mind.

TL;DR: The kinematics and electromyography of the reaction to an unexpected slip were examined simultaneously in 16 young, healthy volunteers to characterize the response to postural perturbation in the context of the perturbations characteristics.

TL;DR: The fat-suppressed FLASH sequence was found to allow the most accurate evaluation of the total volume and the regional distribution of the articular cartilage and can therefore be recommended for experimental and clinical use.

TL;DR: The capacity of neural networks to recognize alteration of gait patterns suggests that they might provide an alternative approach for gait assessment and might be proved to be a useful diagnostic tool.

TL;DR: The results suggest that shock-waves have no beneficial effect in acute fracture repair, and a non-significant tendency to deterioration of the fracture healing with increasing shock-wave intensities.

TL;DR: Performing situps (both dynamic and quasi-static) imposes high levels of compressive loading on the low back, suggesting that using straight legs or bent knees is probably not as important as the issue of whether to prescribe situps at all.

TL;DR: The result of this study demonstrated that the intersegmental sagittal motion of lumbar spine can be obtained with error ranged from 0.05 to 0.56 degrees.
