Introduction: Since people experience fatigue after anterior cruciate ligament injury during exercises, it is important to understand how fatigue affects the biomechanical movement patterns. Therefore, this study aimed to investigate the effect of fatigue on ground reaction force variables during single-leg landing in athletes with a history of an anterior cruciate ligament spr...
[Purpose] The correlations of peak vertical ground reaction force and sagittal angles during single-leg lateral jump-landing with noncontact anterior cruciate ligament injury remain unknown. This study aimed to clarify the correlations between kinematics and impact force during lateral jump-landing. [Subjects and Methods] Twenty active males were included in the analysis. A sagittal-view movie ...
Objective: The link between frequency content of gait ground reaction forces and hearing loss is not well understood. The objective of this study was to investigate the effects of hearing loss on gait ground reaction force frequency content. Methods: Thirty male children were equally divided into a healthy group and a group with hearing loss problems (Deaf group). Frequency content of ground r...
Background and Objective: Due to the disruption of the body’s natural posture because of the loss of interior arch of the foot in people with foot pronation, which may change amount and direction of forces and muscles electrical activity exerted on the foot during running movement, the purpose of this study was to compare ground reaction forces and muscles electrical activity of the ankle...
Introduction: With aging, the pattern of walking is altered, and the person’s ability to walk will be decreased. Also, with the beginning of the aging process, the coordination of the postural control system was disturbed and lead to an unstable condition. A small biomechanical change in the lower limb is significant on postural control. The use of textured foot orthoses leads to improved effic...
[Purpose] This study examined the relationships between joint moment and the control of the vertical ground reaction force during walking in the elderly and young male and female individuals. [Subjects and Methods] Forty elderly people, 65 years old or older (20 males and 20 females), and 40 young people, 20 to 29 years old (20 males and 20 females), participated in this study. Joint moment and...
Blind source separation presents an interest for several applications fields. In this study, focus is on the blind separation of biomechanical signals namely ground reaction force signals. We showed recently in [1, 2], that ground reaction force signals are cyclostationary. Thus, the idea of this paper is to make use of the cyclostationary character of ground reaction force signals to separate ...
Introduction and aim: Taping is a common method used by athletes to improve muscular function. The aim was to assess the immediate effect of femoral external rotational and abductoral taping on three-dimensional ground reaction force characteristics, their time to peak, impulse, displacement of center of pressure, vertical loading rate, and free moment during stance phase of running. Method: 24...
[Purpose] The purpose of this study was to examine limb-dominance and gender differences in the magnitude of the ground reaction force during single-leg lateral jump-landings. We hypothesized that the peak ground reaction force would be larger in the non-dominant leg compared to that in the dominant leg and would be larger in females compared to that in men. [Subjects and Methods] Fifteen femal...
Background and Objectives: Knee joint, like other joints in the body, is affected by defects, injuries and diseases. Genu valgum is one of the most common lower limb complications. The purpose of the present study was to determine the effects of corrective exercises using Thera-Band on components of ground reaction force in boy students with genu valgum during running. Materials and Methods: T...
