BACKGROUND: Comparison of dynamic stiffness of foot joints was previously proposed to investigate pathological situations with changes in the properties of muscle and passive structures. Samples must be controlled to reduce the variability within groups being compared, which may arise from different sources, such as gait speed or foot posture index (FPI). METHODS: In this work, variability in the measurement of the dynamic stiffness of ankle, midtarsal and metatarsophalangeal joints was studied in a controlled sample of healthy adult male subjects with normal FPI, and the effect of gait speed was analyzed...

The objective of the study was to investigate the effect of bariatric surgery-induced weight loss on knee gait and cartilage degeneration in osteoarthritis by combining magnetic resonance imaging, gait analysis, finite element modeling and cartilage degeneration algorithm. Gait analyses were performed for obese subjects before and one-year after the bariatric surgery. Finite element models were created before and after weight loss for those subjects who had not severe tibio-femoral knee cartilage loss. Knee cartilage degenerations were predicted using an adaptive cartilage degeneration algorithm which is based on cumulative overloading of cartilage, leading to iteratively altered cartilage properties during osteoarthritis...

Background: Mental fatigue is a psychobiological state induced by sustained periods of demanding cognitive activity and characterized by feelings of tiredness which are common in everyday life. Recently, it has been hypothesized that mental fatigue might have an impact on gait performance in old adults. Therefore, the effect of mental fatigue on gait performance under single- and dual-task conditions was investigated in young and old participants. Methods: Spatio-temporal gait parameters of 16 young and 16 old healthy participants were measured using a photoelectric system during single- and dual-task walking before and after a randomly assigned mental fatigue (performing a stop-signal task for 90 min) and control intervention (watching a video for 90 min), respectively...

Meloxicam, a preferential COX-2 inhibitor, is a commonly used NSAID in pigs. Besides having potential side effects on the gastrointestinal tract, this type of drug might potentially affect osteogenesis and chondrogenesis, processes relevant to growing pigs. Therefore, the effects of long-term meloxicam treatment on growing pigs were studied. Twelve piglets (n=6 receiving daily meloxicam 0.4 mg/kg orally from 48 until 110 days of age; n=6 receiving only applesauce (vehicle control)) were subjected to visual and objective gait analysis by pressure plate measurements at several time points...

Gait analysis is an important tool for diagnosis, monitoring and treatment of neurological diseases. Among these are hereditary spastic paraplegias (HSPs) whose main characteristic is heterogeneous gait disturbance. So far HSP gait has been analysed in a limited number of studies, and within a laboratory set up only. Although the rarity of orphan diseases often limits larger scale studies, the investigation of these diseases is still important, not only to the affect population, but also for other diseases which share gait characteristics...

AIM: The Short Physical Performance Battery (SPPB) is a widely used instrument for measuring physical performance, consisting of 3 sub-tests: a hierarchical test of balance, a gait speed test, and a chair stand test. Although equally considered in the computation of the SPPB score, each of the components may present a specific and different weight in clinical practice. The aim of this study was to estimate the relationship between SPPB and its component of an age-related deficit accumulation index (the so-called Frailty Index [FI] proposed by Rockwood)...
