Stability is an important concern during human walking and can limit mobility in clinical populations. Mediolateral stability can be efficiently controlled through appropriate foot placement, although the underlying neuromechanical strategy is unclear. We hypothesized that humans control mediolateral foot placement through swing leg muscle activity, basing this control on the mechanical state o...

There are elements in nature that may be compared to some dermatological lesions, such as the black pearl, which is very similar to a cellular blue nevus observed in the gluteus region of a 31-year-old male patient.

This paper introduces a new method for data analysis of animal muscle activation during locomotion. It is based on fitting Gaussian mixture models (GMMs) to surface EMG data (sEMG). This approach enables researchers/users to isolate parts of the overall muscle activation within locomotion EMG data. Furthermore, it provides new opportunities for analysis and exploration of sEMG data by using the...

The gluteus maximus muscle is the largest, heaviest and most coarsely fibred muscle in the body which provides a thick quadrilateral pad over the ischial tuberosity. Structural changes in this muscle are critical to the evolutionary advance toward an upright stance during walking. Although its bilaminar nature' and its deep and superficial segmentation2) are a part of our current knowledge, var...

The human gluteus maximus is a distinctive muscle in terms of size, anatomy and function compared to apes and other non-human primates. Here we employ electromyographic and kinematic analyses of human subjects to test the hypothesis that the human gluteus maximus plays a more important role in running than walking. The results indicate that the gluteus maximus is mostly quiescent with low level...

STUDY DESIGN Case report. BACKGROUND The underlying mechanism of the changes in running mechanics after gait retraining is presently unknown. This case report assesses changes in muscle coordination and kinematics during treadmill running and step ascent in 2 female runners with patellofemoral pain after mirror gait retraining. CASE DESCRIPTION Two female runners with chronic patellofemoral...

Literature has not shown the minimum time required to recover from muscle fatigue after a prolonged trunk isometric contraction. The purpose of this study was to determine if the lumbar multifidus (LM) and gluteus maximus (GM) muscles would recover from fatigue after three different rest periods following performance of a back extension endurance test. Endurance time and electromyographic (EMG)...

Femur fracture is a in the largest bone body. The femur requires significant force to fracture. One of treatments for femoral reduction and immobilization using traction. Immobilization traction-attached patients before preoperatively isometric exercises maintain muscle strength. Isometric exercise contraction exercise, patient contracts muscles without moving prevent atrophy. purpose this pape...
