Morphological and morphometric variability of the small-sized coastal squid Lolliguncula brevis was assessed along the largest part of its latitudinal range in the southern hemisphere, off the Brazilian coast (8º S - 27º S). A general homogeneity in form was found throughout the entire latitudinal range. In terms of body proportions, no latitudinal gradients were evident, but a few local "morph...

Fractures of both the radius and ulna are usually treated with two separate incisions and rarely with one single incision. However, both methods have disadvantages. For this we describe a relatively safe single straight posterior incision for exposure of the whole shafts of both the radius and ulna with the forearm rested on a board across the chest. This procedure was used in 116 forearms in 1...

We reviewed the results of reconstruction of 97 upper limbs in a consecutive series of 57 tetraplegic patients, treated from 1982 to 1990. Of these, 49 had functional and eight had cosmetic reconstructions. The principal functional objectives were to provide active elbow extension, hook grip, and key pinch. Elbow extension was provided in 34 limbs, using deltoid-to-triceps transfer. Hook grip w...

OBJECTIVE Analize data on patients submitted to transfer of the pronator teres (PT) or the flexor carpi ulnaris (FCB) to the extensor carpi radialis longus/brevis (ECRL/B) in order to correct flexed wrist deformity in patients with cerebral palsy. METHOD Patients were divided into two groups: PT group and FCU group to ECRL/B. The results were evaluated by goniometry and by the functional hand...

The representation of joint position at rest and during movement was investigated in 44 muscle spindle primary afferents originating from the extensor carpi radialis brevis (ECRb) and extensor digitorum (ED) of normal human subjects. Position sensitivity was estimated for each afferent, and 43 of 44 were position sensitive. In each trial, six sequential ramp-and-hold movements (2-6 degrees, 2 d...

The aim of the study was to assess the maximum force of the handgrip depending on four different upper limb locations and to analyse the influence of limb location on muscle activities connected with the handgrip force. Five upper limb and shoulder muscles were examined: extensor carpi radialis longus, flexor carpi ulnaris, biceps brachii caput breve, deltoideus pars anterior and trapezius pars...

Background: Despite the growing popularity of bouldering, little is known about degree and variabilityof muscle activation that occurs while solving bouldering problems. The purpose this study was to explorethe electromyography eight upper extremity trunk muscles during a session indoor whilecompleting four different problems.Methods: Eleven climbers with self-reported ability climb V-scale V4 ...

OBJECTIVE To evaluate the activity of wrist extensor muscle, correlating with wrist motion during gripping after flexor tendon repair. DESIGN Cross-sectional clinical measurement study. SETTING Laboratory for biomechanics and rehabilitation. SUBJECTS A total of 11 patients submitted to rehabilitation by early passive motion of the fingers with wrist flexion position were evaluated after 8...

The aim of this study was to assess the muscle functional connectivity obtained from surface electromyogram (SEMG) during unilateral and bilateral texting on a smart-phone as well as standard text entry on a personal computer. Fourteen healthy adults participated in the study. The SEMG signals from the left and right proximal: cervical erector spinae, upper trapezius, lower trapezius and distal...
