چکیده

The surface electromyographic patterns of eight muscles and the foot-contact patterns exhibited by 25 normal persons between the ages of 20 and 40, were measured and studied. These persons were walking indoors on a level surface without shoes at several different self-selected walking speeds. The electromyographic patterns demonstrated a considerable amount of interindividual variability at each speed. There were definite trends in the number of individuals exhibiting each pattern type as walking speed increased. The foot-contact patterns showed a consistent sequencing of foot events at all speeds with the double-limb support stages and stance phase comprising a smaller percentage of the gait cycle as speed increased.

Effect of gait speed on muscle activity patterns and magnitude during stance.

UNLABELLED This study aims to assess the influence of gait speed (manipulated through cadence) on muscle activity patterns and activation degree during stance. METHODS Thirty-five healthy individuals participated in this study. Surface electromyographic activity from the gastrocnemius medialis (GM), gluteus maximus (GMax), biceps femoris (BF) and rectus femoris (RF) was acquired with subjects...

Electromyographic and kinematic nondisabled gait differences at extremely slow overground and treadmill walking speeds.

This study compared the kinematic and electromyographic (EMG) gait patterns of able-bodied adults at natural speed in contrast to extremely slow overground and treadmill walking speeds. Kinematic and EMG data were collected at three speeds (self-selected, 0.30 m/s, and 0.20 m/s). Eighteen subjects were evaluated for trunk and lower-limb motion and EMG of five lower-limb muscles. Significant red...

Biomechanical characteristics of adults walking in shallow water and on land.

Although water environment has been employed for different physical activities, there is little available information regarding the biomechanical characteristics of walking in shallow water. In the present study, we investigated the kinematics, ground reaction forces (GRF), and electromyographic (EMG) activation patterns of eight selected muscles of adults walking in shallow water and on land. ...

Objective: In recent years, it has been focused much attention on gait analysis. Factors such as speed, age and gender affect gait parameters. The purpose of the present study was to compare the electromyographic activity pattern of knee two-joint muscles between younger and older subjects in different gait speeds. Matterials & Methods: The method of current study was analytical cross-sectio...

Biomechanical characteristics of elderly individuals walking on land and in water.

In this study, we examined Spatial-temporal gait stride parameters, lower extremity joint angles, ground reaction forces (GRF) components, and electromyographic activation patterns of 10 healthy elderly individuals (70+/-6 years) walking in water and on land and compared them to a reference group of 10 younger adults (29+/-6 years). They all walked at self-selected comfortable speeds both on la...
