Mechanisms of injury to the iliopsoas may be due to sudden contraction of the hip flexor
muscles while the hip is in a stretched position or during sprinting or kicking activities with the hip extended and stretched above its flexible limit.
Subjects performed a series of maximum voluntary isometric contractions (MVICs) of the trunk extensor and trunk flexor
Maximum isometric force was 1.87 [+ or -] 0.37 times greater in the quadriceps and 0.24 [+ or -] 0.08 times lower in the plantar flexor
muscle group for the subject-specific model (Table 3).

"The psoas muscles originate at the sides of the lower vertebrae (in your spine) and run down through the pelvis, where it joins the iliacus (another hip flexor
) and attaches to the femur or thigh bone," explains Dana Aaron, an advanced clinician at the Weill Cornell-affiliated Hospital for Special Surgery's Sports and Performance Center.
The analysis indicated that ten young soccer players are sufficient to observe large-sized main effects (Cohen's d = 0.8) of condition on measures of plantar flexor
torque (i.e., mechanical peak force).
In the selected CT images with WW = 2350 HU, WL = 1180 HU settings and corresponding sections of the plastinated specimen; the metacarpal bone III and its sagittal ridge, the proximal sesamoid bones, proximal phalanx, middle phalanx, distal phalanx, distal sesamoid bone, branches of the suspensory ligament, collateral ligament, intersesamoidean ligament, deep digital flexor
tendon, superficial digital flexor
tendon, common and long digital extensor tendons were well determined.
Botulinum toxin type A (BTA, Botox, Allergan) was injected into the flexor
muscles of the wrist and fingers including the flexor
carpi radialis 50 U, flexor
digitorum profundus 50 U, flexor
digitorum superficialis 70 U, and flexor
pollicis longus muscle 20 U (190 units in total) under the double guidance of electromyography and electrical stimulation.
In infants, face involvements (42.85%) is more followed by flexor
(28.57%), extensor (14.28%) and both flexor
and extensor (14.28%).
carpi ulnaris muscle (FCUM) is an important muscle in the forearm belonging to the anterior flexor
compartment, and it provides strength to wrist flexion and ulnar adduction.
The average CMAP amplitude of their right forelimb flexor
, which was 420 [+ or -] 226 [micro]V on average before the surgery, changed to 0 [micro]V, and the CMAP amplitude of their right forelimb extensor, which was 536 [+ or -] 391 [micro]V on average before the surgery, was also lost.
