OBJECTIVE The purpose of this study was to compare the torque production in the paretic and non-paretic hands during isokinetic tasks following stroke. METHODS We compared torque and power production at the MCP joint of chronic stroke survivors during isometric and isokinetic tasks. We also recorded surface electromyography (EMG) activity in the forearm muscles. RESULTS Isokinetic torque pr...

Background: Hamstring tendons are secondary hip extensors. Their harvest for graft in anterior cruciate ligament(ACL) reconstruction may create deleterious effect on hip extension strength. This is of particular importance in sportsthat need powerful hip extension force like climbing and sprinting. Due to scarcity of a comprehensive study in thisarea, we designed this prospect...

INTRODUCTION Following anterior cruciate ligament reconstruction (ACLR), strength is a key variable in regaining full function of the knee. Isokinetic strength is commonly used as part of the return to sport (RTS) criteria. AIM We systematically reviewed the isokinetic strength evaluation protocols that are currently being used following ACLR. A secondary aim was to suggest an isokinetic prot...

OBJECTIVES To ascertain whether detailed isokinetic knee muscle testing reflects the results of other functional measurements in footballers and to look for any correlations between quadriceps tendon thickness and knee strength. METHODS Ultrasonographic evaluation of the quadriceps tendon (Hitachi EUB-405), isokinetic knee testing (Biodex System 3), and sprint measurements using telemetric ph...

To investigated whether an acute hypoxic stimulus affects muscle strength development assessed by isokinetic dynamometry during maximal knee extension. A total of 15 healthy young men participated in this study (61.9 ± 6.1 kg; 1.72 ± 0.08 m; 20.9 ± 2.6 years). We evaluated knee extension and flexion isokinetic dynamometer performance in normoxic and hypoxic conditions. The analyzed parameters, ...

BACKGROUND Isokinetic dynamometry is becoming increasingly important for the assessment of muscle function in individuals with intermittent claudication. However, there is still little information available about the cardiovascular responses of these patients during this type of assessment. OBJECTIVE To assess and compare the cardiovascular responses recorded during the assessment of muscle s...

The purpose of this study was to compare three different intervals for a between sets rest period during a common isokinetic knee extension strength-testing protocol of twenty older Brazilian men (66.30 ± 3.92 yrs). The volunteers underwent unilateral knee extension (Biodex System 3) testing to determine their individual isokinetic peak torque at 60, 90, and 120°s(-1). The contraction speeds an...

The primary aim of our study was to evaluate the strength ankle evertor muscles in patients who have undergone a lateral ligamentoplasty (which combined tensioning ligament group and reinforcing it with pediculated extensor retinaculum flap), using 2 measurement systems (isokinetic functional weightbearing test [MyoLux). Our hypothesis on treated side comparable that contralateral healthy side....

BACKGROUND The patellar tendon has limited ability to heal after harvesting its central third. Platelet-rich plasma (PRP) could improve patellar tendon healing. HYPOTHESIS Adding PRP to the patellar tendon harvest site would improve donor site healing and improve clinical outcome at 6 months after anterior cruciate ligament (ACL) reconstruction with a patellar tendon graft. STUDY DESIGN Ran...
