Non-specific low back pain (LBP) is one of the most prevailing health problems worldwide, with a life-time prevalence of 38.9%. In almost 85% of low back pain patients, a patho-anatomical diagnosis cannot be distinguished. The estimation is that between 5.0% and 10.0% of LBP will develop into chronic …

Kinematical joint analysis during road cycling is a new trend. Reviewing the methods for 2D and 3D lower limb kinematical research, the sensor to segment alignment appeared to be the most challenging part due to unknown orientation with respect to the anatomical joints. A methodology that is suitable …

The functional and anatomical distinction between vision-for-perception and vision-for-action, the hallmark of the dual-stream Perception-Action Model, is equally applicable to the auditory domain, implying that non-conscious audition-for-action could play an important role in music performance. Ear …

The seventh ACL Research Retreat was held March 19–21, 2015, in Greensboro, North Carolina. The retreat brought together clinicians and researchers to present and discuss the most recent advances in anterior cruciate ligament (ACL) injury epidemiology, risk factor identification, and injury risk screening …

Dynamic plantar pressure images are routinely used in clinical gait assessment, and peak pressure, mean pressure, and pressure-time integral are the most frequently used parameters to summarize these images. Many studies report only one parameter, but other studies report all three. The interdependency …

Background. Barefoot plantar pressure measurements are routinely used in the risk evaluation for ulceration in diabetic patients with neuropathy. The aim was to compare three step-protocols commonly used for pressure assessment in these patients. Methods. Dynamic barefoot plantar pressures were measured …

Force transmission across the wrist during a grasping maneuver of the hand was simulated for three children with juvenile idiopathic arthritis (JIA) and for one healthy age-matched child. Joint reaction forces were estimated using a series of springs between articulating bones. This method (i.e., rigid …

The purpose of this study is to create an accurate experimental database for the passive (in vitro)freedom-of-motion characteristics of the human knee joint on a subject to subject basis, suitable for the verification and enhancement of mathematical knee-joint models. Knee-joint specimens in a six degree-of-freedom …

In biomechanical joint-motion analyses, the continuous motion to be studied is often approximated by a sequence of finite displacements, and the Finite Helical Axis(FHA) or "screw axis" for each displacement is estimated from position measurements on a number of anatomical or artificial landmarks. When …
