[Purpose] The purpose of this study was to identify the effects of changes in support and inclined boards on lower-extremity muscle activity. [Subjects and Methods] The study subjects were 15 healthy adult males. Aero-Step equipment was used as an unstable support, and an inclined board was used to maintain angles of 0° and 20°. Electromyography was employed to analyze lower-extremity muscle ac...

introduction: peripheral vascular disease (pvd) is a major cause of morbidity and is associated with coronary artery disease (cad). we aimed to perform lower limb perfusion scan (llps) in patients referred for myocardial perfusion imaging (mpi) and estimate prevalence of pvd in subgroups with normal and abnormal mpi results. we also compared quantitative indices of llps in patients with and wit...

Purpose: The present study aimed to investigate the effect of six weeks of Pilates exercises on upper and lower extremities function in middle-aged females with lower crossed syndrome. Methods: This study was a quasi-experimental research with pretest- post-test design. The participants were 30 females with lower crossed syndrome from Tiam Sport Club. They were selected using purposeful sampl...

To provide more comprehensive information on the extent and pattern of muscle activation during running, we determined lower extremity muscle activation by using exercise-induced contrast shifts in magnetic resonance (MR) images during horizontal and uphill high-intensity (115% of peak oxygen uptake) running to exhaustion (2.0-3.9 min) in 12 young women. The mean percentage of muscle volume act...

Selection of muscles for botulinum toxin injection for limb dystonia is particularly challenging. Limb dystonias vary more widely in the pattern of dystonic movement and involved muscles than cervical dystonia or blepharospasm. The large variation in how healthy individuals perform skilled hand movements, the large number of muscles in the hand and forearm, and the presence of compensatory acti...

LEARNING OBJECTIVES After studying this lesson, the reader will be able to do the following: 1. Define the hip and trunk CORE 2. Evaluate the CORE muscles and structure 3. Delineate the difference between local and global muscles on the back 4. Identify the muscles of the abdominal area that are considered stabilizing 5. Identify the spinal muscles that stiffen the spine 6. Evaluate the CORE dy...

The molecular components largely responsible for muscle attributes such as passive tension development (titin and collagen), active tension development (myosin heavy chain, MHC) and mechanosensitive signaling (titin) have been well studied in animals but less is known about their roles in humans. The purpose of this study was to perform a comprehensive analysis of titin, collagen and MHC isofor...
