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 ...

Gulzar Saeed Ahmed1 ABSTRACT Objective: Function and appearance of the involved hand in patients with cerebral palsy can be improved by orthopedic surgery especially in spastic hamiplegia. Flexor carpi unlnaris transfer to extensor carpi radialis longus or bravis is a procedure commonly used for correction of flexion pronation deformity of hand in patients with cerebral palsy. Patients and Meth...

We studied the origin of extensor carpi radialis brevis using 40 fresh frozen human cadaver specimens. Ten were stained with haematoxylin and eosin and trichrome which showed the collagenous structure of the extensor tendons at their origin. Gross anatomical observation showed that there was no definitive separation between brevis and communis at the osseotendinous junction. The histological fi...

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 aim of the study was to compare the theoretical indicator of upper limb load with the physiological indicator of musculoskeletal load, which is present while performing a repetitive task (a normalized electromyography [EMG] amplitude recorded from the muscles of the upper limb involved in the performed task). In an experimental study of a repetitive task, the EMG signal from 5 main muscles ...

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...

[Purpose] The aim of this study was to investigate the effect of vibratory stimulation on maximal voluntary isometric contraction (MVIC) from delayed onset muscle soreness (DOMS). [Subjects] Sixty healthy adults participated in this study. The exclusion criteria were orthopedic or neurologic disease. [Methods] The researchers induced DOMS in the musculus extensor carpi radialis longus of each p...
