A new high accuracy personalised HTO procedure, ToKa,has been created. An in silico trial based on real patient data has demonstrated the mechanical safety equivalence of the personalised ToKa HTO plate and the most commonly used generic plate.

The production of prosthetic socket for a disabled person is made by the hand of the manufacturer, which makes it difficult to maintain the consistency of the quality, and the production time is lengthened and the efficiency of the work is poor. In order to overcome these problems, we have studied t...

We compared posturography and Achilles tendon shear wave speed measures during quiet standing in healthy young adults. We found that wave speed closely tracks fluctuations in the center of pressure, an observation attributable to the direct relationship between wave speed and tendon loading. Both te...

Peripheral quantitative computed tomography (pQCT) can be used to assess the structural and geometrical changes in bone whilst exposing participants to minimal radiation. Structural parameters are analysed automatically, but geometrical measures are not. pQCT images were converted into binary before...

Sea turtles are often involved in propeller accidents and get caught as fishery bycatch where substantial injury also due to predatory attach are an all too often occurring consequence. Mutilated turtles are often unable to manoeuvre them self-back to the water surface due to partial or total limb l...

Load carriage is an essential component of combat related roles in military populations. Warfighters are regularly required to walk at velocities more routinely associated with running, known as forced marching (FM). There is a paucity of research regarding the effects of FM on knee total joint mome...

We evaluated the Pneumatic Ergonomic Crutch (PEC), which consisted of a pneumatically-activated sleeve orthosis worn to improve wrist posture and loading when using a Lofstrand crutch. A spring-loaded piston pump at the PEC crutch tip was used to harvest pneumatic energy for pressuring the orthosis ...

People with transtibial amputation, due to diabetes, vascular diseases, congenital, cancer, or trauma, are custom fitted with a prosthetic limb to regain mobility and independence. However, the cost of the prosthesis varies, depending on the design, materials used, and function of the user. The pros...

We tested the efficacy of real-time biofeedback to augment peak knee extensor moment (KEM) during walking, an outcome relevant to the development of posttraumatic osteoarthritis (PTOA) following knee injury. Subjects averaged changes in peak KEM up to +62% and -57% of normal values, with concomitant...

In this study, three ankle joint models with increasing level of personalisation are compared within a standard musculoskeletal model (MSKM) of the lower limb, integrated with individual ligaments and articular surfaces from magnetic resonance images (MRI) to assess their anatomical consistency. Kin...

There are several methods for computing average vertical loading rate (AVLR) in the literature. In this analysis we developed a novel method (the 3-12% auto method) and compared it to 2 methods of computation previously established in the literature (the 3-12% method and 20-80% method). The 3 method...

The ability to measure whole body vibration exposure in the workplace is important considering its established link to low back pain. We designed and evaluated a wearable device for measuring vibration exposure at the lower back. Experiments were performed on an electromechanical shaker to compare v...

Deficits in quadriceps strength are common following anterior cruciate ligament reconstruction (ACL-R) and can influence alterations in gait mechanics. Functional resistance training (FRT) may improve gait mechanics, yet, the best approach to implement FRT is not clear. Here, we report the acute eff...

When walking at similar speeds, greater positive hip extensor and/or flexor work is thought to compensate for lower positive ankle work during push-off in older versus young adults. Ankle moments contribute to positive ankle work in walking and are reduced in old age. We used induced acceleration an...

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...

It is of interest for health professionals to automatically classify and diagnose diabetic neuropathy (DPN) patients. Therefore, in this study, we initially propose a machine learning based tool capable of discriminating healthy from DPN individuals using motor data from surface electromyography sig...

This study reports on a large investigation to explore the advantages of customisation in total ankle replacement (TAR). Potentially, this can minimise the critical prosthesis-to-bone mismatch, improve the accuracy of the implantation and also facilitate osseointegration. A general customisation pro...

A pronated foot posture has been associated with overuse running injuries. To manage symptoms, foot orthoses have been widely used in symptomatic runners with a pronated foot posture. This study examined the immediate effects of foot orthoses with forefoot corrections on forefoot kinematics during r...

Stability of motor behavior reduces when anticipating or initiating a state change. We explore the effect of anticipated movement and recent history of movement on the stability of the current manual state in a finger-force-production paradigm. We found that stability is reduced in anticipation of s...

In Western riding competitions horses have to walk backward. Therefore, they change its gait pattern, which is clearly visible in the kinematics of the lower limb. This might have some ef-fects on the damping function of the pastern at the lower limbs.

Many surveyed freefall jumpers report musculoskeletal neck pain. This study measured a jumper’s head and body accelerations during parachute opening shock and reported the mean, standard deviation, and range of the accelerations. Data were collected from 18 members of the U.S. Army Parachute Team,...

Researchers recently demonstrated that exoskeleton assistance strategies aimed at keeping the human “in-the-loop” can achieve significant improvements in locomotor performance. Given these findings, we sought to develop an alternative human-in-the-loop strategy rooted in the idea of co-adaptatio...

A systematic review investigating the association between jump-landing mechanics and patellar tendinopathy (PT) was conducted across five electronic databases. Statistically significant variables were identified in 12 studies across five participant cohorts and nine different jump-landing tasks. Cli...

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...

Jump landing manoeuvres in competitive downhill skiing are typical situations leading to ACL injuries. While, neuromuscular control is considered a key injury risk factor, optimum control strategies are unknown. The purpose of the study was to compute muscle activation patterns that minimize ACL for...

The implementation of the non-linear analysis method, Detrended Fluctuation Analysis (DFA), has been hindered by a lack of consistency in its application. Our study sought to establish recommendations for the box size ranges over which the output of DFA, alpha (α), is calculated for postural contro...

With the cyclical changes of the menstrual cycle, women undergo several changes, such as mood, body mass, temperature, postural control and even muscle strength. Thus, the aim of this study was to investigate the relationship between the menstrual period, when the female hormones are lower, and chan...

The purpose of this study was to investigate the changes in the knee joint mechanics in the frontal plane induced by two typical exercise-induced fatigue protocols. Fifteen trained male athletes were recruited. Frontal plane knee joint kinematics and ground reaction forces were recorded. No signific...

This study aimed to compare dynamic foot pressure distributions at different phases of walking in three different foot postures: a normal one (pes planus) and two abnormal ones (pes rectus and pes cavus). Fifteen young subjects participated in this study. At the start of mid-stance, the peak pressur...
