Objective Startling acoustic stimulation (SAS), via activation of reticulospinal (RS) pathways, has shown to increase muscle strength in healthy subjects. We hypothesized that, given RS hyperexcitability in stroke survivors, SAS could increase muscle strength in stroke survivors. The objective was to quantify the effect of SAS on maximal and sub-maximal voluntary elbow flexion on the contralesi...

Athletic injuries of the elbow are common especially in throwing sports such as baseball and tennis. An early diagnosis, early initiation of treatment, and appropriate referrals for surgical management enable athletes to return safely to competition as quickly as possible. Elbow injuries may involve any of the anatomical structures in the region. The normal range of motion at the elbow joint is...

BACKGROUND Recent advances in imaging modalities have enabled three-dimensional preoperative simulation. A four-dimensional preoperative simulation system would be useful for debridement arthroplasty of primary degenerative elbow osteoarthritis because it would be able to detect the impingement lesions. METHODS We developed a four-dimensional simulation system by adding the anatomical axis to...

BACKGROUND The objectives of this study were to characterize the translational and rotational accuracy of a model-based tracking technique for quantifying elbow kinematics and to demonstrate its in vivo application. METHOD OF APPROACH The accuracy of a model-based tracking technique for quantifying elbow kinematics was determined in an in vitro experiment. Biplane X-ray images of a cadaveric ...

PURPOSE The function of the brachioradialis muscle is controversial. The objective of this study was to determine primary and secondary functions of the brachioradialis under various loading tasks as measured by EMG. METHODS Ten healthy individuals (9 men, 1 woman; average age, 34 years +/- 10; average height, 175 cm +/- 7; average weight, 76 kg +/- 13) performed elbow flexion with the forear...

The natural course of untreated posterior lateral rotatory instability of the elbow is unclear. A case of elbow arthrosis with progressing deformity and flexion contracture after an episode of elbow dislocation about 20 years ago presented the possibility the long term outcome of untreated posterior lateral rotatory instability of the elbow.

OBJECTIVES To investigate outcomes after surgical repair of distal biceps tendon rupture and the influence of arm dominance on isokinetic flexion and supination results. BACKGROUND/PURPOSE While relatively uncommon, rupture of the distal biceps tendon can result in significant strength deficits, for which surgical repair is recommended. The purpose of this study was to assess patient reported...

SATO, K., NAKAMURA, R. and NAGASAKI, H. EMG Activities of the Biceps Brachii at Rapid Elbow Flexion during Passive Movements. Tohoku J. exp. Med., 1983, 139 (2), 219-220 Seven normal subjects were asked to flex the left elbow as quickly as possible, responding to a tone stimulus under three conditions: 1) during passive flexion of the elbow, 2) during passive extension and 3) without passive mo...

results the results of this study showed high reliability and validity of smartphone in regarding ug with icc > 0.95. the highest reliability for both methods was in elbow supination and the lowest was in the elbow flexion (0.84). objectives the study was designed to compare the smartphone inclinometer-based app and ug in evaluation of rom of elbow. materials and methods the maximum rom of elbo...
