This study presents a novel approach towards balance assessment during continuous perturbed walking conditions with complex external perturbation profiles. Stability measures defined in this study are based on a seven-segment model of the human body in the sagittal plane.

Exoskeletons can augment the capacity of humans and enhance mobility in the disabled. Often it is required to understand how varied levels of assistance affect the metabolic cost. Experimental studies investigated the effect of varied assistance on metabolic cost for different exoskeletons . Simulat...

Adults with obesity are at greater risk for knee osteoarthritis (KOA). Greater quadriceps function, but not knee flexion during gait, was associated with a larger medial to lateral femoral cartilage thickness ratio and a lower femoral cartilage echo-intensity. Adverse femoral cartilage outcomes that...

The relationships between general fall risk and standing measures during ladder use were assessed both with and without a concurrent cognitive task. Individuals with higher fall risk scores had increased time to complete the ladder task and reduced dual-task performance. Other ladder standing parame...

Hip-related pain is a common cause of lower-limb musculoskeletal pain and a potentially debilitating diagnosis in football players. This study aimed to examine the relationship between hip strength and hip joint kinematics during walking, to assist in the development of targeted interventions.

Asymmetric loading such as carrying bags and side-pack on one side of the body alter individuals’ gait, posture, as well as trunk and lower extremity biomechanics. The primary hip abductor, gluteus medius, is the main contributor for pelvic stabilization during ambulation and dynamic functional ac...

As a part of “Non-operative treatment of Achilles tendon Rupture in Central Finland: a prospective cohort study – NoARC” results from the first 12 patients who completed biomechanical assessments 1 year after active, structured, and functional non-surgical treatment of acute Achilles tendon (A...

The objective of the study was to report axial stiffness changes in participants with low back pain (LBP) after two weeks of treatment with a non-thrust chiropractic spinal manipulative technique (flexion-distraction). Twelve participants with LBP (age 18-65; mean: 42) were recruited for this study....

This study used a finite element (FE) model to determine the spinal loads, and stress distribution in the intervertebral discs (IVDs) of an adult trunk with intact, as well as with the unilaterally weakened muscles under the equivalent loading condition, as an alternative to in vivo loading conditio...

Simulations and experimental studies show that it is possible to reduce loads in joints that are not directly assisted by an exoskeleton. In this presentation, we will give an overview of proximal effects of ankle exoskeletons as well as preliminary results on distal effects of a robotic waist tethe...

The purpose of the current study was to investigate the association between upper body joint motions and propulsive efficiency in pediatric manual wheelchair users. The results highlight the role of wrist motion in the optimization of the force applied to the pushrim during manual wheelchair propuls...

Characterization of mechanical load under realistic conditions provides meaningful context for injury risk in runners. The purpose of this study was to determine how reaction forces (RFs) experienced immediately after foot contact were associated with swing and stance leg accelerations measured by i...

The aim of this study was to establish the relationship between asymmetries in muscle strength, activation, and joint kinetics during running. Between-limb differences in peak sagittal plane ankle and knee joint moments during running, isometric plantarflexor and knee extensor strength at three knee...

The purpose of this ongoing study is to assess back extension endurance time and muscle fatigue of university students with and without history of low back pain (LBP). To date, 11 graduate students (5 with and 6 without LBP) have participated, and the final sample will be 30 (15/group). The electrom...

Ballroom dancing is a popular global activity, with interested participants spanning decades. The goals of this preliminary study are to evaluate two biomechanical assessment tools, pressure sensing insoles and inertial markers, or combining both tools to facilitate the collection of objective, quan...

Plantar fascia shear modulus was assessed in healthy participants, participants with plantar fasciitis and active pain, and participants with a history of plantar fasciitis, but no current pain. Plantar fascia stiffness was lower in the symptomatic group than either the healthy or asymptomatic group...

Second anterior cruciate ligament (ACL) injuries occur in about 29% of patients following return to sport. Asymmetric movement patterns are associated with second ACL injury risk during landing. A negative psychological response during recovery has been associated with decreased gait symmetry. This ...

Runners with active plantar fasciitis (PF) (n=28) demonstrated higher vertical load rates (LRs) compared to healthy controls (CON). These differences were consistent across rearfoot strikers (RFS) and forefoot strikers (FFS). Further, FFS appeared to exhibit higher lateral LRs, where RFS showed lowe...

Bone loading due to daily physical activity over one week, was quantified from accelerometer data. Moderate-to-vigorous loading was positively associated with bone health of the left proximal femur. Adopting this level of activity in daily living may have sustained benefits for healthy ageing of bon...

The ability to use reactive stabilization strategies to recover from a slip or a trip is vital for preventing falls. Physiological impairments after stroke, such as weakness and delayed sensorimotor processing may reduce the effectiveness of rapid stepping responses to restore balance following unex...

Automated plantar pressure (PP) masking can improve reporting time, remove human error/bias, and standardize masking methods when used for PP-based gait analysis. Twenty participants walked while optical motion capture cameras tracked 3-dimensional locations of the markers and a PP mat simultaneousl...

The origin and current state of the ISG group will be introduced. By reviewing the presentations of the past ISG meetings, general trends of developments will be highlighted. As examples, the three invited speakers will be introduced.

Reactive balance training (RBT) using trip-like perturbations on a treadmill was implemented for four weeks among independent older adult residents of retirement communities. Training-induced improvements in trunk kinematics could be predicted from only trunk kinematics following trip-like perturbat...
