چکیده
Results The following are the findings. Firstly, the total time taken for forward breakfall of the martial arts showed 1.53±0.04 s for skilled, and 1.41±0.06s for unskilled subjects (p<.01). Second, during forward breakfall of the martial arts, the skilled subjects came up with significantly faster impact velocity in the primary point of impact (E2) (p<.001), but the unskilled subjects showed significantly faster impact velocity in the secondary point of impact (E3) (p<.001). Third, the forward breakfall of the martial arts did not show any difference between left and right side in the reaction force, but unskilled subjects proved a significantly greater forward and backward reaction force in the secondary point of impact(E3) both right and left sides (right: p<.01, left: p<.001). The skilled subjects showed a significantly greater vertical reaction force in the primary point of impact (E2) (right: p<.001, left: p<.001), and unskilled subjects showed a larger vertical reaction force in the secondary point of impact (E3), respectively (right: p<.01, left: p<.05).

Temporal pattern in segmental motions of the foot in healthy senile adults: comparison between young and senile healthy adults
The incidence of foot and ankle disease increases as the age increases [1,2]. However, there was no report about differences of foot motion between senile person and young adults. The purpose of this study is to analyze distinctions according to age in segmental foot motion using 3D multifoot model from healthy senior and young adults. One hundred senile (50 males, 50 females) and young adults ...
متن کاملDynamic Analysis of Foot Models for Human Locomotion
Human locomotion dynamics has been a topic of interest since the past few decades. In many areas such as as humanoid robot design, gait rehabilitation, diagnosis of pathologies, prosthesis design, sport analysis, and motion cognition, the human locomotion is needed to be properly modelled. Dynamics of human locomotion, and the capability of implementing an accurate human gait simulation can be ...
متن کاملA comparison of the free moment pattern between normal and hyper-pronated aligned feet in female subjects during the stance phase of gait
Background: Excessive range of adductory free moment of the ground reaction force may potentially increase the risk of lower extremity injuries by applying a higher torsional load transmitted to the proximal parts. Objective: It was hypothesized that the free moment pattern might be different between hyper-pronated and normal feet subjects. Moreover, a correlation would exist between peak...
متن کاملDesign and Evaluation of an Articulated Ankle Foot Orthosis with Plantarflexion Resistance on the Gait: a Case Series of 2 Patients with Hemiplegia
Ankle-foot orthoses (AFOs) have been described to have positive effects on the gait biomechanics in stroke patients. The plantarflexion resistance of an AFO is considered important for hemiplegic patients, but the evidence is still limited. The purpose of this case series was to design and evaluate the immediate effect of an articulated AFO on kinematics and kinetics of lower-limb joints in str...
متن کاملAnalysis of a kinetic multi-segment foot model. Part I: Model repeatability and kinematic validity.
Kinematic multi-segment foot models are still evolving, but have seen increased use in clinical and research settings. The addition of kinetics may increase knowledge of foot and ankle function as well as influence multi-segment foot model evolution; however, previous kinetic models are too complex for clinical use. In this study we present a three-segment kinetic foot model and thorough evalua...
