purpose: this study aimed to examine the differences in the co-activation of the rectus femoris (rf) and biceps femoris (bf) using the co-contraction index (ci) in aquatic and land environments during a drop-landing task in active and non-active females. methods: in this casual-comparison study, 10 active and 10 non-active females volunteered to participate. the ci was calculated from recorded ...

First, a bit of historical background adapted from the founding documents of the American Society of Biomechanics (original author unknown)... The American Society of Biomechanics (ASB) was founded in 1977 by a group of 53 scientists and clinicians. There were at the time several regional and national organizations in the United States that regularly or occasionally assigned portions of their b...

Plenty of analyses based on Biomechanics were carried out on many jobs in manufactures or services. Now Biomechanics analysis is being applied on mothers who are giving birth. The analysis conducted in terms of normal condition of the birth process without Gyn Bed (Obstetric Bed). The aim of analysis is to study whether it is risky or not when choosing the position of mother’s postures when del...

Background: Injuries to the fibular collateral ligament (FCL) seldom occur in isolation and may present with a concomitant injury biceps femoris tendon anterior cruciate (ACL). structures of posterolateral corner (PLC) lead varus rotational instability knee, subjecting ligaments increased forces that result graft failure. Therefore, reconstruction these should be performed concurrently ACL. Ind...

results daily administration of 50 mg/kg ptx (groups 1 and 2) decreased the high stress load in repairing osteotomized femurs when compared with the control group. the highest dose of ptx (200 mg/kg) significantly increased the high stress load when compared with the control group (p = 0.030), group 1 (p = 0.023), group 2 (p = 0.008), and group 3 (p = 0.010), per the lsd findings. materials and...
