Functional implications of muscle co-contraction during gait in advanced age

Muscle Activity And The Quantification Of Co-Contraction At The Knee During Walking Gait

INTRODUCTION It is commonly agreed that one of the greatest challenges in the study of human motion is the development of accurate, non-invasive methods to calculate individual force-time histories during movement [1]. Furthermore, in the field of medicine it is widely advocated that in surgical decisions for the management of such orthopedic conditions as cerebral palsy, muscle balance must be...

The Effect of Exhaustive Protocol on Knee Muscle Co-contraction in Healthy People and with a Pronated Foot during Running

Background and Aim: Fatigue and abnormalities in the lower extremities, such as the pronated foot, can adversely affect the biomechanics of human movements such as running, leading to a lack of muscle contraction and unstable symptoms in the joints of the lower extremities (knees). Therefore, the main purpose of this study was to investigate the effect of exhaustive protocol on knee muscle co-c...

Assessment of Trunk Muscle Co-contraction during Multi-axial Movements

INTRODUCTION It has been well documented that individuals with chronic low back pain (CLBP) tend to exhibit different muscle activation patterns in the trunk musculature when compared with healthy individuals. Studies investigating the flexion relaxation phenomenon have observed the persistence of muscle activation during full trunk flexion in CLBP [1], while Silfies et al. [2] found that CLBP ...

Methodologies to assess muscle co-contraction during gait in people with neurological impairment - a systematic literature review.

PURPOSE To review the methodologies used to assess muscle co-contraction (MCo) with surface electromyography (sEMG) during gait in people with neurological impairment. METHODS The Scopus (1995-2013), Web of Science (1970-2013), PubMed (1948-2013) and B-on (1999-2013) databases were searched. Articles were included when sEMG was used to assess MCo during gait in people with impairment due to c...
