A case of traumatic hallux varus due to avulsion fracture of the lateral side of the base of proximal phalanx was reported. The lateral instability of the first metatarsophalangeal joint was believed to be due to the disruption of adductor hallucis function. It was successfully managed by minimally invasive extensor hallucis brevis tenodesis.

PURPOSE To provide a cadaveric analysis of 3 surgical approaches (anterior, anterolateral, posterior) used for decompression of the posterior interosseous nerve within the radial tunnel. The aim of the study was to determine whether the number of compression sites visualized and safely released differed between approaches. We hypothesized that no single approach is adequate for visualization of...

Brevenal is a ladder frame polyether produced by the dinoflagellate Karenia brevis. This organism is also responsible for the production of the neurotoxic compounds known as brevetoxins. Ingestion or inhalation of the brevetoxins leads to adverse effects such as gastrointestinal maladies and bronchoconstriction. Brevenal shows antagonistic behavior to the brevetoxins and shows beneficial attrib...

BACKGROUND There is a high prevalence of non-specific shoulder pain associated with upper limb functional limitations in older adults. The purpose of this study was to determine the minimal clinically important differences (MCID) of grip strength and pressure pain threshold (PPT) in the upper limb between older adults with or without non-specific shoulder pain. METHODS A case-control study wa...

1. Human extensor carpi radialis brevis (ECRB) sarcomere length was measured intraoperatively in five subjects using laser diffraction. 2. In a separate cadaveric study, ECRB tendons were loaded to the muscle's predicted maximum tetanic tension, and tendon strain was measured to estimate active sarcomere shortening at the expense of tendon lengthening. 3. As the wrist joint was passively flexed...

Long-term adaptation (LTA), a phenomenon previously studied in the crayfish claw, was examined in one of the motoneurones innervating the phasic abdominal extensor muscles. The motoneurone was conditioned by electrically stimulating the second root of the third abdominal ganglion in situ for 4 h per day, using trains of stimuli with an average impulse frequency of 2-5 Hz. In juvenile crayfish, ...

Objectives: This study presents a method of assessing muscle fatigue during endurance testing at 50% maximal voluntary contraction (MVC) using electromyography (EMG) information as indirect indices fatigability in the forearm muscles, namely, flexor digitorum superficialis (FDS); carpi ulnaris (FCU); extensor (ECU) and radialis brevis (ECRB)." (ECRB). Methods: A randomized comparative experimen...

Objective: This study investigated the neuromuscular control of increasing and releasing force in patients with chronic lateral epicondylitis (CLE). Methods: Fifteen CLE (10 males, 5 females, 46.5 ± 6.3 years) fifteen healthy participants (9 6 45.3 2.5 participated this study. In addition to power grip maximal voluntary contraction (MVC) wrist extension, fluctuation dynamics characteristics int...
