BACKGROUND Assessment of circulating volume and the requirement for fluid replacement are fundamental to resuscitation but remain largely empirical. Passive leg raise (PLR) may determine fluid responders while avoiding potential fluid overload. We hypothesised that inferior vena cava collapse index (IVCCI) and carotid artery blood flow would change predictably in response to PLR, potentially pr...

On curves, non-amputees' maximum running speed is slower on smaller radii and thought to be limited by the inside leg's mechanics. Similar speed decreases would be expected for non-amputees in both counterclockwise and clockwise directions because they have symmetric legs. However, sprinters with unilateral leg amputation have asymmetric legs, which may differentially affect curve-running perfo...

Why is maximal running speed reduced on curved paths? The leading explanation proposes that an increase in lateral ground reaction force necessitates a decrease in peak vertical ground reaction force, assuming that maximum leg extension force is the limiting factor. Yet, no studies have directly measured these forces or tested this critical assumption. We measured maximum sprint velocities and ...

non-discogenic sciatica can be caused by any lesion along the course of the lumbosacral nerve roots and sciatic nerve. we aim to present a rare case of refractory sciatica in an otherwise healthy 25-year-old man. he complained of left leg pain without significant back pain. extensor hallucis longus muscle was weak on the left side with limited straight leg rising. on magnetic resonance imaging,...

Our goal was to examine ground reaction forces (GRF) following a series of unanticipated jump landing and cutting tasks (JLC) and the differences in these GRF’s associated with leg dominance. Nine recreationally active (at least 3x/week of running, cycling, aerobics, or recreational sports participation) right leg dominant females with no history of lower extremity injuries participated in the ...

OBJECTIVES Neurodynamic exercises aim to improve neural mechanosensitivity in order to promote pain-free movement and function. People with diabetes mellitus (DM) may be candidates for neurodynamic exercises to address common DM-related impairments such as reduced lower extremity range of motion (ROM) and altered neural mechanosensitivity. However, no studies have examined the safety and immedi...

BACKGROUND Lumbar pathologies may cause the perception of leg pain, but the character of this pain has not been described. Diagnosis is often based on dermatomal charts, but observations reveal that the pain is not typically perceived on the skin. OBJECTIVE To document the incidence of superficial versus deep pain localization among patients with lumbar radicular pain. METHODS Twenty-five p...

BACKGROUND In children with cerebral palsy (CP), stiffness, caused by contractile and non-contractile structures, can influence motor performance. This study sought to determine whether the nerve mobility had a relevant impact on motor performance in children with CP. We hypothesized that a positive Straight Leg Raise (SLR) test, as well as smaller SLR hip angle, would relate to lower leg muscl...
