We have investigated the patterns of activation of epaxial musculature during both swimming and overground stepping in an adult newt (Pleurodeles waltl) with the use of electromyographic (EMG) recordings from different sites of the myomeric muscle dorsalis trunci along the body axis. The locomotor patterns of some limb muscles have also been investigated. During swimming, the epaxial myomeres a...

BACKGROUND Stepping-down is preceded by a shift of the center of mass towards the supporting side and forward. The ability to control both balance and lower limb movement was investigated in knee osteoarthritis patients before and after surgery. It was hypothesized that pain rather than knee joint mobility affects the coordination between balance and movement control. METHODS The experiment w...

Objectives: This study aimed to investigate the effect of upper extremity coordination exercises based on fatigue prediction on fine and gross manual dexterity, upper limb motor function, shoulder and elbow proprioception, occupational performance, and activities of daily living in chronic stroke survivors. Methods: In this pilot double-blind randomized clinical trial, 24 chronic strokes were ...

Every day, we visually coordinate our movements with environmental rhythms. Despite its ubiquity, it largely remains unclear why certain visual rhythms or stimuli facilitate such visuomotor coordination. The goal of the current study was to investigate whether the velocity profile of a rhythmic stimulus modulated the emergence and stability of this coordination. We examined both intended (Exper...

Objectives: To assess the effectiveness of mirror therapy (MT) on upper limb (UL) function of sub-acute stroke patients. Methods: This study is a single case experimental design with two participants. Twenty minutes of MT were implemented four times a week over a period of four weeks. For baseline phase, repeated measurements were performed six times for one participant and four times for the ...

Vertebrate limb development is controlled by three signaling centers that regulate limb patterning and growth along the proximodistal (PD), anteroposterior (AP) and dorsoventral (DV) limb axes. Coordination of limb development along these three axes is achieved by interactions and feedback loops involving the secreted signaling molecules that mediate the activities of these signaling centers. H...

Focal motor syndromes are reported in 57 instrumental musicians who presented with painless uncoordinated movement of the upper limbs. Three stereotyped afflictions were noted: flexion of the 4th and 5th fingers in pianists, flexion of the 3rd finger in guitarists, and extension of the 3rd finger in clarinetists. Our patients differed from those with generalised dystonia in that their disabilit...

ABSTRACT Introduction: The research on vibration training has experienced a period of development in many projects, such as badminton, handball, long jump, and volleyball. However, there is still no quantitative evaluation its effects the shoulder, elbow, upper limb muscle strength volleyball athletes. It believed that specific protocol with may bring benefits to sensory-motor performance imple...

In this paper, we report the effect of physical exercise on motor skills in autistic children. This is important because the number of autistic children has rapidly increased in these years. Autism is a disorder that covers a wide range of motor, cogni-tive and behavioral disturbances and influences personal and social conduct of the individual (1). Due to the fact that children with autism are...
