Evaluating active translational shoulder stability is essential to quantifying clinically-relevant deficits in individuals with shoulder instability. Estimating impedance with random perturbations allows for this assessment of active translational stability that is not possible with clinical techniq...

This Abstract summarizes a novel automated system to introduce stumble-inducing gait perturbations that are: (1) realistic, (2) are unanticipated by subjects, and (3) accurately controllable in their timing. Furthermore, this system (4) allows for kinematic and kinetic evaluation before and after th...

We examined differences in submaximal quadriceps force control between test protocols and the relationship between quadriceps force control and pain and function in individuals with knee osteoarthritis (OA). Ten participants with symptomatic and radiographic knee OA were recruited. Self-reported pai...

For understanding intervertebral disc (IVD) degeneration associated back pain and for the development of suitable treatment strategies, it is important to know how mechanical influences regulate cellular responses and their impact on disc physiology and pathology. Understanding of IVD mechano-biolog...

In vitro experiments allow to determine biomechanical properties directly from real complex structures. Such studies are important for basic understanding of the healthy, degenerated or injured spine. These data are also necessary for validation or calibration of finite element models. But in vitro ...

Suryanamaskar is a Yogic sequence of 12poses alternating between flexion-extension and synchronized with breathing, holding huge potential to improve spine joint motion, muscle strength and postural control.[1] Present study aimed to explore effect of Suryanamaskar intervention on spine pain, kinema...

Patellofemoral Pain Syndrome (PFPS) is a condition impacting the anterior knee and is exacerbated with running, squats, climbing stairs, or prolonged sitting. Altering running cadence, using a metronome (5-15% above baseline) has been shown to decrease knee joint forces and pain in individuals with ...

Despite the generally accepted importance of form & force closure mechanisms in sacroiliac joint (SIJ) biomechanics, very little is known about SIJ form and orientation, and the relationship between both. This study describes the sagittal orientation of the SIJ relative to gravity, and defines its c...

We analysed the rate of torque development (RTD) drop-off characteristics of forty anterior cruciate ligament (ACL) reconstructed (ACLR) subjects during maximal quadriceps voluntary isometric contractions (MVIC). We found that the RTD of ACLR limbs drops at a lower percentage of their maximum torque...

Persons in symptom remission from recurrent low back pain (rLBP) and back-healthy persons performed a single-limb dynamic balance task with and without a concurrent mental math task. Thorax and pelvis frontal plane motion was less coupled in the group in remission from rLBP and was associated with t...

Spinal cord injury (SCI) begins with mechanical insult to the cord (i.e. primary injury), followed by a myriad of biological events such as ischemia, inflammation, etc. that further damage the cord (i.e. secondary injury). The wide variability, or heterogeneity, in human SCI is due partially to biom...

Soft tissue motion can contribute to energy losses during locomotion. Energy losses due to soft tissue motion were calculated using marker arrays on the shank soft tissue during different foot strike patterns and running velocities on a group of runners. Energy losses associated with damped soft tis...

In vivo large animal experiments are essential where the biological response is imperative to the research question. Such studies may be used to answer fundamental questions about the spine and spinal cord in healthy, diseased and injured states, or for the pre-clinical evaluation of procedures and ...
