It is well known that in a Kalman filtering framework, all sensor observations or measurements contribute toward improving the accuracy of state estimation, but, as observations become older, their impact toward improving estimations becomes smaller to the point that they offer no practical benefit. In this paper, we provide an practical technique for determining the merit of an old observation using system parameters. We demonstrate that the benefit provided by an old observation decreases exponentially with the number of observations captured and processed after it...

BACKGROUND: Individuals with trans-tibial amputation show a greater peak prosthetic ankle power (push- off) when using energy storing and returning (ESAR) prosthetic feet as compared to solid-ankle cushion-heel feet. ESAR feet further contribute to the users' body support and thus limit prosthetic ankle motion. To improve ankle motion, articulating prosthetic feet have been introduced. However, articulating feet may diminish push-off. RESEARCH QUESTION: Does a novel prosthetic foot, with a serial layout of carbon fibre leaf springs, connected by a multi-centre joint construction, have advantages in kinematics and kinetics over a conventional ESAR prosthetic foot?> METHODS: Eleven individuals with unilateral trans-tibial amputation were fitted with the novel foot (NF) and a conventional ESAR Foot (CF) and underwent 3D gait analysis...

BACKGROUND: Neoadjuvant chemotherapy followed by surgery and adjuvant chemotherapy is the most-frequently employed strategy for patients with high-grade osteosarcoma. However, the contribution of neoadjuvant chemotherapy compared with postoperative adjuvant chemotherapy has not been tested rigorously in patients with nonmetastatic high-grade pelvic osteosarcoma. QUESTIONS/PURPOSES: (1) Does neoadjuvant chemotherapy followed by delayed surgery offer a survival benefit to patients with nonmetastatic high-grade pelvic osteosarcoma compared with immediate surgery and adjuvant chemotherapy? (2) Is the timing of chemotherapy and surgery associated with a difference in the survivorship free from local recurrence and the risk of complications? (3) Is the threshold of 90% necrosis after neoadjuvant chemotherapy appropriate to distinguish responders from nonresponders in patients with pelvic osteosarcoma? METHODS: Between 2000 and 2015, our center treated 112 patients with nonmetastatic high-grade primary pelvic osteosarcoma, of whom 93 underwent tumor resection with chemotherapy...

BACKGROUND: To evaluate participant-related variables associated with missing assessment(s) at follow-up visits during a longitudinal research study. METHODS: This is a prospective, longitudinal, multi-site study of 196 acute respiratory distress syndrome (ARDS) survivors. More than 30 relevant sociodemographic, physical status, and mental health variables (representing participant characteristics prior to ARDS, at hospital discharge, and at the immediately preceding follow-up visit) were evaluated for association with missed assessments at 3, 6, 12, and 24-month follow-up visits (89-95% retention rates), using binomial logistic regression...

Previous studies have shown that walking is associated with increased longevity and a reduced risk of cardiovascular and age-related diseases. Whether walking benefits individuals with diabetes who are at high risk of coronary heart disease (CHD) remains to be determined. The objective of this study is to examine the association between walking and risk of CHD among elderly men with and without diabetes. Walking data was assessed in 2732 men aged 71 to 93 years participating in the Honolulu Heart Program from 1991-1993...

People can acquire new walking patterns in many different ways. For example, we can change our gait voluntarily in response to instruction or adapt by sensing our movement errors. Here we investigated how acquisition of a new walking pattern through simultaneous voluntary correction and adaptive learning affected the resulting motor memory of the learned pattern. We studied adaptation to split-belt treadmill walking with and without visual feedback of stepping patterns. As expected, visual feedback enabled faster acquisition of the new walking pattern...

Background: Walking and cycling for transport (active travel) is an important source of physical activity with established health benefits. However, levels of physical activity accrued during public transport journeys in England are unknown. Methods: Using the English National Travel Survey 2010-14 we quantified active travel as part of public transport journeys. Linear regression models compared levels of physical activity across public transport modes, and logistic regression models compared the odds of undertaking 30 min a day of physical activity...

BACKGROUND: Esophagectomy performed via thoracotomy is associated with a high rate of postoperative pulmonary complications. Video-assisted thoracoscopic surgery at the esophagus (VATS-E) can reduce the rate of postoperative pulmonary complications. VATS-E is being increasingly implemented owing to its benefits. This procedure makes early patient mobilization possible, because there is minimal thoracic wall invasion, and thus, less postoperative pain. This study aimed to identify the efficacy of early mobilization in patients undergoing VATS-E...

BACKGROUND: Older adults have twice as many disabilities and four times as many physical limitations as people <60 years of age. Positive influence of physical activity to prevent these limitations has been presented in some studies. However, the indispensable combination of physical abilities and body composition parameters to maintain independence in later life and their relationship with physical activity has not been studied thoroughly. OBJECTIVE: The main aim of this study was to determine possible differences in body composition and mobility parameters among older women with various levels of engagement in physical activity...

We describe qualitative and quantitative development and preliminary validation of the Patient Assessment for Low Back Pain - Impacts (PAL-I), a patient-reported outcome measure for use in chronic low back pain (cLBP) clinical trials. Concept elicitation and cognitive interviews (qualitative methods) were used to identify and refine symptom concepts. Classical test theory and Rasch measurement theory (quantitative methods) were used to evaluate item-level and scale-level performance of the PAL-I using an iterative approach between qualitative and quantitative methods...

BACKGROUND: Contralesional 'drop foot' after stroke is usually treated with an ankle-foot orthosis (AFO). However, AFOs may hamper ankle motion during stance. Peroneal functional electrical stimulation (FES) is an alternative treatment that provides active dorsiflexion and allows normal ankle motion. Despite this theoretical advantage of FES, the kinematic and kinetic differences between AFO and FES have been scarcely investigated. OBJECTIVE: To test whether walking with implanted FES leads to improvements in stance stability, propulsion, and swing initiation compared to AFO...

BACKGROUND: Poor performance in physical tests such as grip strength and walking speed is a risk factor for disability in old age, although whether such measures improve the discrimination of clinical prediction models when traditional clinical risk factors are already known is not clear. The prevalence of disability in mid-life is relatively low and hence screening in this age group may present an opportunity for early identification of those at increased future risk who may benefit most from preventative interventions...

BACKGROUND: Physical activity (PA) participation and adherence among cancer survivors is low, despite research indicating numerous physical, psychological and emotional health benefits of exercise. Tailoring exercise programs specific to the PA preferences in cancer survivors has merit for increasing PA participation and adherence to accrue these benefits. This systematic review identifies and differentiates PA programming and counseling preferences of adult cancer survivors across various cancer survivor groups...

PURPOSE: Little is known about the effects of early mobilization in older adults in the Cardiovascular Intensive Care Unit (CICU). MATERIALS AND METHODS: We reviewed consecutive patients ≥60 years of age admitted to the CICU at an academic tertiary care center from 2016 to 2017. The level of function (LOF) was assessed prehospital, at CICU admission, and at CICU transfer using a graded scale ranging from LOF 1 (bedbound) to 4 (walk > 50 ft). The prehospital frailty status was assessed using Rockwood's Clinical Frailty Scale...

Gait dysfunctions in Parkinson's disease can be partly relieved by rhythmic auditory cueing. This consists in asking patients to walk with a rhythmic auditory stimulus such as a metronome or music. The effect on gait is visible immediately in terms of increased speed and stride length. Moreover, training programs based on rhythmic cueing can have long-term benefits. The effect of rhythmic cueing, however, varies from one patient to the other. Patients' response to the stimulation may depend on rhythmic abilities, often deteriorating with the disease...
