New interventions for spinal pathologies can be tested on computational models of the spine without putting the patient at risk. However, existing models are usually built from different datasets which may be inconsistent with each other. In this study, a full body musculoskeletal model was develope...

Segmentation of anatomical tissues from medical images is extremely time consuming and is prone to human error. Historically, automated methods have produced insufficient accuracy and have been computationally expensive. This investigation tested a custom two-stage deep learning framework that achie...

Plantarflexor functional deficits are associated with poor outcomes in patients following Achilles tendon rupture. In this study, we established the link between changes in gastrocnemius structure with plantarflexor function 3 months after injury. We found that deficits in peak isokinetic torque wer...

The diaphragmatic ligament (DL) provides the pressure barrier separating thorax from abdomen in mammals. It has a microarchitecture that resists hoop stresses and herniation and provides a biaxial elastic layer of elastin. Modelling of the microarchitecture reveals how the ligament could transpose i...

It is important to understand the kinematics of deep knee flexion due to the difficulty patient have performing this activity. bfPCA can describe variability across the entire movement cycle and also identify patterns which a-priori feature identification cannot. The aim of this study was to use to ...

Fragile X Syndrome (FXS) is a genetic condition, mainly characterized by intellectual disability and behavioural problems. In subjects with this syndrome, delays in the acquisition of the main stages of psychomotor development are commonly observed. This project aims to investigate associations betw...

Current methods for quantifying gait improvement in idiopathic normal pressure hydrocephalus (iNPH) are subjective and incomplete. This study demonstrates that patients with iNPH who have undergone ventricular peritoneal (VP) shunt placement demonstrate improvements in gait but still are impaired in...

For analysing the biomechanics of gait steady state velocity should be reached. With ramp construction the walkway is limited and it is not clear if the same rules for reaching speed steady state as for level walking apply over a range of downhill inclines. Therefore, temporo-spatial, kinematic and ...

Gait, considered by many, is distinguishable between individuals, making gait a viable security measure. The long-term goal of this research is to identify specific individuals wearing clothing with a high level of accuracy using a convolutional neural network (CNN). In this study, a supervised bina...

The aim of this study is to investigate how the gait kinetics of elderly change after stair negotiation. The Ground Reaction Force (GRF) during walking can be an important descriptor of human locomotion and can describe disturbance in gait. The GRF measurement of 33 female subjects (70.48±6.66 yrs)...

Inverse dynamic (ID) analyses of baseball pitchers have assumed body segment inertial properties scaled from total body weight and segment lengths. In our recent study [1], use of dual energy X-ray absorptiometry (DXA) segment masses produced higher shoulder kinetics than use of scaled masses. The a...

Performance-based function and self-report (balance, health, prosthetic use) comparisons were made between individuals with transtibial osteomyoplastic (Ertl) and non-Ertl amputations. Functional task results found significantly greater functional ability in those with an Ertl amputation. No differe...

We used Non-negative Matrix Factorization (NMF) to discover muscle modules (groups of co-activated muscles) of patients with post-stroke hemiparetic gait before and after gait retraining. Patients who have suffered a stroke often have an impaired gait due to the merging of these modules, which are d...

The Functional movement screen (FMS) is an assessment tool for identifying physical weaknesses and asymmetries prevention potential injury. There has been plenty of FMS documents regarding to many sports. However, there are few FMS documents been conducted for baseball. Therefore, the purposes of th...

Chronic ankle instability (CAI) has been associated with kinematic and kinetic deficits during walking. However, few studies simultaneously investigated these two modalities during walking, which is necessary to better understand the deficits associated with CAI. The objective of this study was to q...

Mounting evidence reveals deficits in dynamic gait balance control persist in individuals with acute mild traumatic brain injury (mTBI) when assessed with sensitive whole body center of mass (COM) kinematics and a dual-task (DT) paradigm [1]. In this preliminary study eight veterans with symptoms of...

People with dementia have impairments in gait that are associated with an increased risk of falls. The aim of this study was to investigate the relationship between gait features extracted from repeated, frequent gait assessments and future falls in older people with dementia. We found that gait ins...

After lateral lengthening of the calcaneus patients have different gait patterns during uphill walking compared to healthy subjects. Push-off phase was particularly altered with a more extended knee joint than healthy subjects and a lower ground reaction force compared to the contralateral leg.

The basis for identifying stance and swing phase to classify gait requires the accurate estimation when major gait events such as initial contact and toe off occur. This study examines the ability of the Beta Process Autoregressive Hidden Markov Model (BP-AR-HMM) to estimate initial contact and toe ...

Our understanding of the relationship between 3D bone shape and knee osteoarthritis (OA), as well as our ability to investigate potential causative factors of OA, has been hampered by the time intensive nature of manually segmenting bone from MR images. Thus, we aim to develop and validate a fully a...

Functional data analysis (FDA) provides a powerful alternative to traditional digital filtering for analysing time-series data. In this study, FDA applied to repeated throwing trials facilitates comparison of curve shapes and key features.

This study demonstrates the feasibility of applying quadriceps FES during walking as a new method to overcome quadriceps muscle weakness during early rehabilitation post-ACLR. Compared to NMES, patients who received FES achieved better results in quadriceps strength and symmetry. While both interven...

In this work we present a control algorithm for restoring movements in paralyzed limbs through functional neuromuscular stimulation (FNS). We employed a nonlinear model predictive controller (NMPC) in conjunction with an Extended Kalman Filter (EKF). Both the NMPC and EKF were equipped with a neurom...

Examining the effects of prolonged running on gait mechanics is needed to understand the multifactorial nature of running injury. However, the window of opportunity to capture the effects of a sub-exhaustive prolonged run on gait is unknown. Five runners completed overground motion capture before an...

Individuals with bipolar disorder (BPD) exhibit gait abnormalities during symptomatic phases, but whether gait patterns are affected during asymptomatic phase is not known. Accordingly, this study aimed to describe gait patterns in asymptomatic individuals with BPD (n=14) as compared to healthy cont...

A recent survey in India reported a point prevalence of 43.5% low back pain among dancers amongst which a large majority were Indian classical dancers namely, Bharatanatyam. In an attempt to explore the source of low back pain, 7 Bharatanatyam dancers presenting with low back pain during walking wer...

We applied a PCA-based technique to extract functional movement components and the corresponding activity of the neuromuscular controller from kinematics data in people with DS. Specific abnormalities were found in frontal-plane control.
