This study compares muscle fiber conduction velocities during isometric maximal voluntary contraction in different degrees of diabetic neuropathy classified by a fuzzy expert model. Sixty-seven diabetic patients of both sexes were classified by a fuzzy expert system in four groups according to the neuropathy degree: absent, mild, moderate and severe. Average muscle fiber conduction velocities o...

The specific aim of this study was to quantify muscle activity while performing squat with technique variations. Eight healthy volunteers performed squats under 5 types of foot positions: neutral position, under a 10o descending wedge, under a 10o ascending wedge, under a 10o medial wedge and under a 10o lateral wedge. It was evaluated electromyographic data of vastus medialis oblique, vastus l...

Patellofemoral pain syndrome (PFPS) is one of the most common knee disorder seen by clinicians. The main region of pain is the lateral aspect of the patellofemoral joint. Force imbalance in the knee extensor muscles has been associated with changes in patellofemoral tracking [1] and is suspected to cause PFPS. Weakness of the vastus medialis (VM) relative to the vastus lateralis (VL) is the usu...

The purpose of this study is to analyse the interlimb relation and the influence of mechanical energy on metabolic energy expenditure during gait. In total, 22 subjects were monitored as to electromyographic activity, ground reaction forces and VO2 consumption (metabolic power) during gait. The results demonstrate a moderate negative correlation between the activity of tibialis anterior, biceps...

INTRODUCTION Heterotopic ossification (HO) is the formation of bone in soft tissues. The purpose of the present study was to evaluate the magnetic resonance imaging (MRI) findings on clinical suspicion of HO in the knee joint of patients hospitalised in the intensive care unit (ICU). METHODS This was a case series of 11 patients requiring prolonged ventilation in the ICU who had the following...

The aim of this study was to investigate the possible kinematic and muscular activity changes with maximal loading during squat maneuver. Fourteen healthy male individuals, who were experienced at performing squats, participated in this study. Each subject performed squats with 80%, 90%, and 100% of the previously established 1 repetition maximum (1RM). Electromyographic (EMG) activities were m...

Baker's cysts are one of the most common cystic lesions around the knee joint and mainly caused by fluid distension of the gastrocnemius-semimembranous bursa that is situated along the medial side of the popliteal fossa. Typically, a Baker's cyst extends along the intermuscular planes around the knee joint and may enlarge any direction. However, it is mostly located in the inferomedial or super...
