Download or read book Leg Muscle Activation Patterns During Sit to stand on Various Compliance Surfaces written by Vadim Zaika and published by . This book was released on 2012 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this thesis was to analyze EMG activity patterns during sit-to-stand (STS) movement on various compliance surfaces. The main hypothesis was to investigate if there were any differences in lower limb muscle activation patterns on various compliance surfaces during sit-to-stand tasks. A secondary hypothesis was to look if there were any significant bilateral differences in muscle activation between left and right legs on various compliance surfaces. Research was conducted at a biomechanical lab at California State University, Northridge (CSUN). Supporting surface stiffness was modified with four eight-way adjustable-stiffness shock absorbers mounted between two force plates. A custom built platform was also used in this experiment. Seventeen CSUN student volunteers were recruited randomly by a pool of volunteers. Each participant performed a self-paced STS under eight surface stiffness conditions in randomized order. The mean EMG values of ten muscles during STS on various compliance surfaces were analyzed and compared according to eight distinct phases of force profile. There were no statistically significant differences found in mean EMG of the muscles examined under different supporting surface stiffness conditions. Right and left leg muscle activities were highly correlated in all phases and not significantly different. It was found that muscle activation patterns during sit-to-stand do not significantly change with variations of the surface compliance, suggesting that a sit-to-stand movement skill is preprogramed in a consistent way under all conditions. Regardless of the surface compliance left and right leg muscles were highly synchronized showing strong synergies. This study suggests that there were no neuromuscular adaptations to difference compliance surfaces in STS, but it is suggested to investigate whether long adaptation periods on a softer compliance surface environment will create any different results.

Download or read book Effects of Aging on Muscle Activation Patterns and Postural Control During Sit to stand and Balance Recovery from Medio lateral Perturbations Across Different Initial Foot Positions written by Woohyoung Jeon and published by . This book was released on 2020 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: We investigated the effects of initial foot position (IFP) on muscle activation patterns and postural control during sit-to-stand (STS) and balance recovery from medio-lateral (M-L) perturbations and how they are different between younger and older adults. In study 1, the effects of different symmetric and asymmetric IFPs on leg muscle activation patterns and balance during and after a STS were examined. A faster forward velocity of the body’s center of mass (CoM) was required in more anterior symmetric IFPs and the greater forward velocity of the body’s CoM caused more postural sway following completion of upright stance. In the one-third back non-dominant leg with two-thirds back dominant leg asymmetric IFP from a 90° knee flexion, the weight-bearing symmetry was not different from the symmetric IFPs and postural stability after STS was improved. In study 2, we investigated the effects of different IFPs and aging on muscle activation patterns and balance during and after a STS. We found that the trunk forward-tilt angle and hip extension torque during uprising were smaller in TO and Wide for both age groups. Postural sway and center of pressure sway area were smallest in TO after completion of uprising with no difference between age groups. Adductor longus and gluteus medius activity was also greater in TO, and older adults activated these muscles more than younger adults in this IFP. This study showed that smaller trunk flexion with greater activation of the hip ab/adductor muscles in TO can contribute to improving postural stability during the STS. Study 3 evaluated the effects of IFPs and aging on changes in muscle activation patterns, kinematics, and postural sway during standing balance recovery in response to unexpected sudden M-L ground perturbations. We observed that M-L standing balance recovery starts with a reflex response to control the body’s CoM position immediately. Although the fibularis longus activity at the ankle joint is smaller in older adults, toes-out IFP provides greater activation of the soleus and fibularis longus and smaller increments of postural sway following perturbations in both age groups. The findings from these series of studies show that IFPs change leg muscle activation patterns and kinematics during a balance recovery motion and influence balance maintenance. These findings are important for designing strength and balance exercise interventions for clinical populations to improve dynamic balance and prevent falls

Download or read book Multiple Muscle Systems written by Jack M. Winters and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 818 pages. Available in PDF, EPUB and Kindle. Book excerpt: The picture on the front cover of this book depicts a young man pulling a fishnet, a task of practical relevance for many centuries. It is a complex task, involving load transmission throughout the body, intricate balance, and eye head-hand coordination. The quest toward understanding how we perform such tasks with skill and grace, often in the presence of unpredictable pertur bations, has a long history. However, despite a history of magnificent sculptures and drawings of the human body which vividly depict muscle ac tivity and interaction, until more recent times our state of knowledge of human movement was rather primitive. During the past century this has changed; we now have developed a considerable database regarding the com position and basic properties of muscle and nerve tissue and the basic causal relations between neural function and biomechanical movement. Over the last few decades we have also seen an increased appreciation of the impor tance of musculoskeletal biomechanics: the neuromotor system must control movement within a world governed by mechanical laws. We have now col lected quantitative data for a wealth of human movements. Our capacity to understand the data we collect has been enhanced by our continually evolving modeling capabilities and by the availability of computational power. What have we learned? This book is designed to help synthesize our current knowledge regarding the role of muscles in human movement. The study of human movement is not a mature discipline.
