Hypertrophic white crystal deposits consistent with gouty tophi are seen surrounding the
extensor digitorum communis of the index finger and extensor indicis proprius tendon.
Pairwise comparisons with Sidak post hoc test revealed Instrument B generated significantly more muscle activity when compared to instruments A and C (p=0.016) (p=0.041) at the 50th percentile affecting the flexor pollicis longus and
extensor digitorum communis, respectively.
The superficial interval between the extensor carpi radialis brevis and the
extensor digitorum communis was incised and the supinator muscle belly was exposed (Figs.
The MeCFES recorded the myoelectric activity from the 2/3 proximal part of the forearm at the level of innervation zones of extensor carpi radialis, extensor carpi ulnaris, and/or
extensor digitorum communis as appropriate for the residual volitional activity of the patient.
(4) Electromyography (EMG), which has been identified as the best technique with respect to localizing the lesion, (6) confirmed normal motor unit potentials (MUP) with full recruitment from the left triceps, brachioradialis, ECRL, and ECRB as well as reduced recruitment with a variable degree of positive sharp waves and fibrillation potentials from the
extensor digitorum communis (EDC), ECU, EI, APL, extensor pollicis longus (EPL), and extensor pollicis brevis (EPB) muscles.
The anterior surface contains attachments for the ECRB and
extensor digitorum communis muscles, which are in fact part of the common extensor tendon origin.
The tendons of extensor carpi radialis longus, extensor carpi radialis brevis (ECRB),
extensor digitorum communis and the extensor carpi ulnaris make up the common extensor origin of the elbow.
(6,7) Key trigger points include: (8) Key trigger point Associated satellite trigger point sternocleidomastoid temporalis, masseter upper trapezius temporalis, masseter scalene deltoid, extensor carpi radialis,
extensor digitorum communis splenius capitis temporalis supraspinatus deltoid, extensor carpi radialis infraspinatus biceps brachii pectoralis minor flexor carpi radialis, flexor carpi ulnaris latissimus dorsi triceps brachii, flexor carpi ulnaris serratus posterior superior triceps brachii,
extensor digitorum communis, extensor carpi ulnaris quadratus lumborum gluteus maximus, piriformis piriformis hamstrings hamstrings gastrocnemius, soleus
He had weakness of
extensor digitorum communis and extensor pollicis longus and was able to completely extend the wrist resulting in some radial deviation.
b) Flexor carpi radialis (FCR) to
extensor digitorum communis (EDC) tendons for finger extension,
Double or triple
extensor digitorum communis (EDC) to long fingers, single or triple EDC to ring finger and single or double EDC to small finger (3).
EMG electrodes were attached to the left forearm to record the muscle activity of the underlying finger flexors (flexor digitorum superficialis) and finger extensors (
extensor digitorum communis; Basmajian, 1978; Delagi, Perotto, Iazzetti, & Morrison, 1975).
