Patients or Programs: A 14-year-old boy with lumbosacral plexopathy after gunshot wounds. Program Description: The patient presented to acute care after 2 gunshot wounds to the abdomen, which required multiple procedures, including a laparotomy and left thoracotomy for abdominal aortic repair. He had an L3 fracture and paraspinal hematoma, with paresthesias and left lower extremity (LLE) weakness. He was given a lumbar sacral orthosis and an ankle-foot orthosis. Upon admission to acute rehabilitation, his LLE strength was 2-/5 to 3-/5 except 0/5 for dorsiflexion. He had LLE tingling. Electrodiagnostic testing revealed positive sharp waves in the left tibialis anterior, peroneus longus, tibialis posterior, tensor fascia lata, gastrocnemius, vastus medialis and rectus femoris, and gluteus maximus with reduced recruitment patterns on strong effort. There was no response on sensory nerve action potentials in the left superficial and sural nerves. Findings were consistent with a left lumbosacral plexopathy with the L5 root most severely involved. Setting: A pediatric rehabilitation unit in a tertiary care hospital. Results: The patient made significant functional gains, with improvements in bed mobility, transfers, and ambulation. Upon discharge, he was independent in activities of daily living and ambulated 100 ft modified independent with a cane. He was without further improvement of innervation of LLE or gait pattern as an outpatient. He is pending reimaging and electrodiagnostics and possible plexus exploration for adhesions. Discussion: The patient presented with a lumbosacral plexopathy after trauma, an L3 fracture, paraspinal hematoma, and abdominal surgery. Lumbosacral plexopathy is relatively uncommon because the plexus has a rich blood supply. It presents with motor and sensory deficits in a distribution of multiple nerves that originate from the plexus. Etiologies include pelvic injuries or tumors, hemorrhages, trauma, ischemia, inflammation, and postpartum injury. Conclusions: Lumbosacral plexopathy is rare, has varying etiologies, and may cause severe neurologic deficits. Electrodiagnostic testing can be diagnostic

Recognizing post-polio syndrome
Bartfeld H; Ma D
1996 May;31(5):95-7, 101, Hospital practice (office edition)
The disorder consists of fatigue accompanied by new muscle weakness and muscle pain or, for patients whose acute polio had included bulbar involvement, new difficulty in swallowing or change in voice. The epidemiology remains unclear, fueling anxiety among polio survivors. Yet its course is not drastically progressive, and impairment is usually limited

A noninvasive technique to assess completeness of spinal cord lesions in humans
Gianutsos J; Eberstein A; Ma D; Holland T; Goodgold J
1987 Oct;98(1):34-40, Experimental neurology
The effect of scalp stimulation delivered through electrodes overlying the motor cortex was evaluated in five healthy subjects and six patients with traumatic spinal cord injury. The latency to the onset of the electromyographic response was measured in the biceps brachii and abductor pollicis brevis muscles. In all the patients, latencies to the muscle (biceps brachii) whose innervation originated above the lesion were in the normal range; whereas, latencies to the muscle (abductor pollicis brevis) whose innervation originated below the lesion were prolonged. Electromyographic signals were recorded in muscles which showed no voluntary motor activity. No lateral differences in latencies were found in healthy subjects; however, in the patients, significant differences were obtained between the right and left abductor pollicis brevis muscles. The results of this study demonstrate that the spinal cord of patients with a lesion deemed to be clinically complete, contains nerve fibers which descend through the lesion and are capable of conveying impulses leading to muscle contraction

Physical therapy management of the patient with post-polio syndrome. A case report
Twist, D J; Ma, D M
1986 Sep;66(9):1403-1406, Physical therapy
This case report documents the treatment of a patient who experienced progressive muscle weakness and a decrease in function over time that did not appear to be related to any secondary neuromuscular disease. We discuss the relationship between age and maximal muscle function in addition to some general guidelines for rehabilitation. This type of patient can represent a challenge for the physical therapist. This case report, however, illustrates the degree of muscular and functional recovery that can result with a physical therapy program aimed at reducing levels and intensity of exercise, daily activity, and stress. Such a combination of short-term goals appears to be essential to the successful management of a patient with post-polio syndrome

Posterior interosseous syndrome revisited
Carfi J; Ma DM
1985 Jul-Aug;8(6):499-502, Muscle & nerve
The question of how the supinator syndrome and the posterior interosseous syndrome are (or are not) related has not been well discussed in the literature. The anatomy of the radial nerve and its innervations is quite variable, as are the etiology, presentation, and clinical findings in the lesions of the posterior interosseous nerve. The present study was based on a retrospective review of the electrodiagnostic records of 12 patients with involvement of the deep radial nerve (posterior interosseous nerve) diagnosed at the EMG lab of New York University Medical Center from 1975 to 1983. Two-thirds of these patients had electrophysiologic abnormalities of the supinator muscle, and in the remainder, the supinator was not involved. All superficial radial nerves had normal evoked mode action potential amplitudes and latencies. We propose that the supinator syndrome is a special case of the posterior interosseous syndrome

Sensory conduction study of distal radial nerve
Ma DM; Kim SH; Spielholz N; Goodgold J
1981 Nov;62(11):562-564, Archives of physical medicine & rehabilitation
The technique of recording superficial radial sensory nerve action potential (SNAP) from the thumb was compared with that of recording from the 1st web space. The spread of stimulus to the median nerve in the forearm when stimulating the radial sensory nerve with relatively high intensity was also investigated. Recording the radial SNAP from the 1st web space produces a larger amplitude response with a sharper takeoff point compared with that of recording from the thumb. Furthermore, with the former technique, the radial SNAP is uncontaminated by a component arising in the median distribution which makes interpretation of its configuration more reliable
