This priceless booklet for the electromyographer dispenses the most recent innovations detailing equipment of intramuscular electrode placement. the writer examines the elemental rules in electromyography (EMG) and contains up-to-date info for the appendicular and axial muscle tissues. it truly is divided into 14 sections geared up through anatomical quarter: the muscle mass of the hand, forearm, arm, shoulder girdle, foot, leg, thigh, pelvis, hip joint, perineal zone, paraspinal sector, belly wall, the intercostals and diaphragm areas, besides the muscle groups innervated by way of cranial nerves. this data comprises the innervations and attachments of every muscle, how you can place the sufferer for exam, the suitable website for insertion of the electrode, the intensity of insertion for the electrode, and the motion that the sufferer may still practice to turn on the muscle. The descriptions of the concepts used for not often tested muscle groups are enough for a clinician to have the boldness had to practice the process. universal error in electrode placement and clinically proper reviews are illustrated and mentioned, together with cross-sectional illustrations at the appendicular muscle tissues. a very invaluable inclusion is 'Pitfalls' that describes which muscle the electrode will checklist if the needle is put too deep, now not deep adequate, or no longer on the position defined. The textual content incorporates a helpful appendix, delivering dermatomes of the limb and trunk, cutaneous innervations of the pinnacle, and ideal illustrations of either the brachial plexus and the lumbo-sacral-coccygeal plexus. The appendix additionally includes a worthwhile desk directory all muscular tissues which are offered within the textual content with innervations from the peripheral nerve to the combined spinal nerve root. good equipped, in actual fact and concisely written, this publication is still a studying device and ideal reference for electromyographers and for healthcare practitioners who're increasing their perform abilities to incorporate diagnostic EMG, in addition to for graduate scholars who use EMG as a part of their study.

27 28 Anatomical Guide for the Electromyographer Electrode Insertion (X) Just proximal to the joint and radial to the flexor tendon. Test Maneuver The usual method of testing lumbrical function by extending interphalangeal joints with the metacarpophalangeal joint in flexion is not possible because it physically interferes with the electrode. The preferred method is to maintain the metacarpophalangeal joints in extension and extend the interphalangeal joints against resistance. The metacarpophalangeal joints have direct relationship with both the proximal (PPC) and the distal (DPC) palmar creases.
Lumbricals 29 Pitfalls First Lumbrical: If the electrode is inserted too deeply it will be in the adductor pollicis; if deeper it will be in the first dorsal interosseus. Second Lumbrical: If the electrode is inserted too deeply it will be in the most ulnar fibers of the adductor pollicis, if deeper the electrode will pierce the aponeurosis, and it will be in the second dorsal interosseus. Third Lumbrical: If the electrode is inserted too deeply it will pierce the aponeurosis, and it will be in the second volar interosseus.
Fourth Lumbrical: If the electrode is inserted too deeply it will be in the opponens digiti minimi; if deeper the electrode will pierce the aponeurosis, and it will be in the third volar interosseus. Comments (a) Only 30 to 50 percent of hands have classically described innervation of first and second lumbricals being median innervated and the third and fourth being ulnar innervated. (b) When classical innervation is present, median nerve entrapment or injury may result in involvement of the first and second lumbrical while ulnar nerve injury or entrapment may result in third and fourth lumbrical involvement.
