According to epidemiological data, muscular dysfunctions of the masticatory system occur in 15-23% of the population. Preventive examinations of functional disorders of the stomatognathic system are, therefore, of particular importance. A distinct group of patients exposed to dysfunctions in the area of the masticatory organ locomotor apparatus comprises those with genetic diseases characterised by disorders in collagen formation. One of such diseases is osteogenesis imperfecta (OI) and dentinogenesis imperfecta that usually goes together with the former...

Shoulder impingement syndrome (SIS) is the common cause of shoulder pain and disability and the individuals suffering from it are usually in different levels of physical activity covering an extensive age range. In spite of limited scientific evidence for an altered motor pattern in the shoulder muscles of patients with SIS, they are frequently referred to physiotherapists in an attempt to optimize coordination and strength of the affected muscles. The aim of this study was to compare scapular muscle activity in a general population of subjects with and without SIS during an arm elevation task executed at different speeds in two load conditions...

It is largely unknown how the CNS regulates multiple muscle systems in the presence of pain. This study used muscle synergy analysis to investigate multiple forearm muscles in individuals with chronic elbow pain during the development of grip force. Eleven individuals with chronic elbow pain and 11 healthy age-matched controls developed grip force to 15% and 30% of MVC. Surface EMG was obtained from six forearm muscles during force development before non-negative matrix factorization was performed. The relationship between muscle synergies and standard clinical tests of elbow pain were examined using linear regression...

Natural variability of myoelectric activity during walking was recently analyzed considering hundreds of strides. This allowed assessing a parameter seldom considered in classic surface EMG (sEMG) studies: the occurrence frequency, defined as the frequency each muscle activation occurs with, quantified by the number of strides when a muscle is recruited with that specific activation modality. Aim of present study was to propose the occurrence frequency as a new parameter for assessing sEMG-signal variability during walking...

AIMS: Women with functional voiding dysfunction often experience a "catching" sensation when catheterising and are in general investigated with both urethral pressure profilometry (UPP) and sphincter electromyography (EMG). It is unknown whether the pattern of the UPP trace correlates with this sensation of "catching" or with sphincter EMG findings. METHODS: We reviewed the database of all women with voiding dysfunction who had undergone both sphincter EMG and UPP to assess for any relationship between pattern of UPP trace and "catching" on catheterization and/or sphincter EMG findings...

Flight is the defining characteristic of birds, yet the mechanisms through which flight ability develops are only beginning to be understood. Wing-assisted incline running (WAIR) and controlled flapping descent (CFD) are behaviors that may offer significant adaptive benefits to developing birds. Recent research into these forms of locomotion has focused on species with precocial development, with a particularly rich data set from chukar partridge (Alectoris chukar). Here we briefly review the kinematics and aerodynamics of flight development in this species...
