The human sensorimotor system can be readily entrained to environmental rhythms, through multiple sensory modalities. In this review, we provide an overview of theories of timekeeping that make this neuroentrainment possible. First, we present recent evidence that contests the assumptions made in classic timekeeper models. The role of state estimation, sensory feedback and movement parameters o...

background: intramuscular injection is one of the effective methods of drug administration. yet the procedure is painful and avoided if at all possible. this study examines the effectiveness of simultaneous rhythmic breathing and z – track method in prone position with foot internal rotation on reducing the pain of intramuscular injection. methods: this quasi experimental (before and after) stu...

a 30-year-old woman presented with a palpable subcutaneous nodule in the areolar region of the left breast. sonomammographic examination revealed 2 cystic lesions showing typical “filarial dance” as vigorous twirling movement of multiple curvilinear echoes with mixed red blue color doppler signals that was non-rhythmic, nonpulsatile, and the characteristic pulse doppler trace due to irregular w...

Mechanosensory neurons from a proprioceptor (the femoral chordotonal organ) signal the movements and positions of the femorotibial joint of a locust leg. Intracellular recordings from these neurons during walking show that their spikes are superimposed on a depolarizing synaptic input generated near their output terminals in the CNS. The depolarization consists of a rhythmic synaptic input at e...

relaxation is one of the important mental skills in physical education and sportsactivities. relationship between relaxation and rhythmic exercises with anemphasis on flexibility-functional mechanisms of nervous system has receivedattention in recent studies. the aim of the present study was to investigate the effectof rhythmic exercises on deepening the relaxation of national judo athletes. fo...

the aim of this study was to examine the effect of a rhythmic motor program on the perceptual – motor abilities (pma) and the intelligence quotient (iq) of educable mentally retarded (emr) children. the sample consisted of 24 emr girls (mean age = 11.98+1.43 years and iq = 70.58+ 9.95). then, they were matched and assigned to two groups of intervention and control according to their iq and pma ...
