BACKGROUND Muscle fatigue has high relevance in human performance yet little research has evaluated how it should be assessed. OBJECTIVE To perform a pilot study to identify suitable methods of generating and assessing fatigue of the trunk flexor and extensor muscles. METHODS Sixteen university rugby players (mean (SEM) age 21.9 (0.2) years) were recruited and subjected to four protocols (A...

A quantitative study of hindlimb kinematics during terrestrial locomotion in a non-specialized salamander was undertaken to allow comparisons with limb movements in other groups of tetrapods. Five Dicamptodon tenebrosus were videotaped at 200 fields s-1 walking on a treadmill. Coordinates of marker points on the salamander's midline, pelvic girdle and left hindlimb were digitized through at lea...

Treatment of the posterior cruciate ligament (PCL) is a matter of continued controversy in total knee arthroplasty. By using so-called cruciate ligament-substituting implant designs, retention and resection of the PCL produce equivalent clinical results. However, it remains unclear whether primary resection of the PCL leads to relevant instabilities of the flexion gap. Especially when the incre...

PURPOSE To assess the effect of each step of medial soft-tissue releases on the joint gap angle during posterior-stabilised total knee arthroplasty (TKA). METHODS 82 women and 9 men (mean age, 72 years) with medial osteoarthritic knees underwent 100 posterior-stabilised TKAs, in which release of superficial fibres of the medial collateral ligament (MCL) were required using the gap control tec...

The signs associated with an upper motor neurone syndrome vary considerably between text books. Often included are loss of dexterous, rapid and fractionated voluntary movements, variation of movement with mode of activation (prime mover, synergist, antagonist), weakness, various postural signs (eg, pronator drift), time-dependent tonal and tendon reflex changes and the extensor plantar response...

Background and Study Aim. It can be said that recently, with the popularity of women's football playing at a professional level, physical physiological needs have increased. In this context, study was conducted to examine relationship between isokinetic lower extremity strength vertical jump parameters in elite female players. Material Methods. The model research relational survey model, one mo...

Objective: Evaluate the impact of Chevron and extended techniques associated with Akin osteotomy on range motion (ROM) hallux metatarsophalangeal joint (MPJ) interphalangeal (IPJ) after three months one year. Methods: Sixteen patients (17 feet) were evaluated for ROM MPJ IPJ pre-and postoperatively, flexion-extension measurements performed using a goniometer. Results: Comparing postoperative at...

Objective: Postoperative knee range of motion (ROM) is among the most important factors influencing patient satisfaction after total knee arthroplasty (TKA). The purpose of this study was to clarify the time course of improvement in knee ROM up to 12 months after TKA, including intraoperative knee ROM after implantation, and to clarify a target ROM for rehabilitation after TKA. Patients and Met...

[Purpose] This study investigated the flexion-relaxation phenomenon of the erector spinae in elderly women with chronic knee osteoarthritis and determined whether the flexion-relaxation phenomenon can be used as a pain evaluation tool in such cases. [Subjects and Methods] Seventeen elderly females with chronic knee osteoarthritis and 13 healthy young females voluntarily participated in this stu...
