摘要:

Electromyographic responses to needle-electrode insertion and repetitive indirect stimulation were recorded from gastrocnemius, soleus and cranial tibialis muscles of normal and dystrophic (mdx) mice at 20-154 days. Recordings from myotonic (ADRmto) mice served as controls for “true” myotonia. Complex repetitive discharges were observed in muscles of mdx mice but no complex repetitive discharges or other abnormalities were observed in muscles of normal control mice. Complex repetitive discharges in mdx muscles did not resemble the prolonged, abnormally repetitive discharges observed in myotonic mouse muscles. Neuromuscular blockade with tubocurarine and nerve transection had no effect on observed electromyographic abnormalities in the mdx mice. Nerve conduction and repetitive stimulation studies also revealed no abnormalities in mdx mice. These findings indicate that the mdx condition is a nonmyotonic, primary myopathy. No signs of myotonia or impaired neuromuscular transmission were found in mdx mice.

摘要:

Wegener's granulomatosis is a multisystem disease distinguished by a triad of necrotizing granulomatous vasculitis involving the upper and lower respiratory tracts, glomerulonephritis and systemic, small vessel vasculitis. The latter can cause neurologic manifestations when the vasa nervorum are affected. A 53-yrold male presented with a 3-mo history of chronic nasal congestion, arthralgias, pruritic maculopapular eruption, epistaxis and lower extremity weakness. Subsequent lung and chest wall biopsies confirmed diagnosis of Wegener's granulomatosis. Summary of electrodiagnostic data obtained on initial presentation and comparison with later study indicated a sensorimotor polyneuropathy with widespread axonal involvement noted particularly in the distal lower extremity musculature. Electrodiagnostic documentation of rapid progression proved useful in directing alteration of immunosuppressive therapy, with favorable clinical and functional outcome. We believe this is the second case presented of a patient with documented Wegener's granulomatosis and overt clinical evidence of polyneuropathy in whom both electroneurographic and electromyographic studies are described. Electrodiagnostic results are presented with discussion of pertinent literature.

摘要:

Lymphedema is a common and often distressing consequence of the management of breast cancer. This is the first report of new onset lymphedema 30 yr after radical mastectomy for the management of breast cancer. The patient's swelling began 10 days after commencing daily finger sticks to follow blood sugar, stemming from a recent diagnosis of diabetes mellitus. If proper precautions had been observed, swelling may not have developed. The patient had marked reduction of her edema with appropriate use of graded compression garments and self administered massage therapy, after early recognition and prompt intervention into her problem. This case highlights efforts that need to be made to prevent the development of edema.

摘要:

5 ng/ml) in 93% of the cycles in which endocrine measures were obtained; but the ability of basal body temperature pattern to predict serum progesterone was low (43%). Cyclic dysmenorrhea was reported by 13 women with injuries ranging from C5 to T12. These findings suggest that ovulatory menstrual cycles are common in women after traumatic spinal cord injury and support the need for contraception by those wishing to avoid pregnancy. Basal body temperature charts revealed potential problems in applying the symptothermal method of natural family planning to a population of women at risk for oral contraceptives.

摘要:

Analyzing multiple nerve conduction study parameters individually is statistically problematic. The goal of this study was to develop a useful factor analysis scheme for assessment of nerve conduction study abnormalities in diabetic neuropathy. Hypotheses were: (1) factor analysis produces a few physiologically meaningful factors, (2) there are associations between factors and markers of diabetic severity and (3) clinical impressions are related to factor scores. We studied 165 Japanese-American men: 52 nondiabetic, 66 diabetic and 47 with impaired glucose tolerance. One author (W.C.S.) obtained 28 nerve conduction study parameters in all subjects and factor analysis extracted five factors from these parameters. These factors were related to conduction velocities (factor 1), distal ulnar function (factor 2), sensory amplitudes (factor 3), distal median function (factor 4) and distal peroneal function (factor 5); together, they explain 57% of the variability in the total data. Diabetic factor scores were significantly (P<0.05) below that of the controls and correlations with fasting blood sugar were significant at the P<0.001 level. Use of this technique promises to permit sensible analysis of large amounts of data in clinical studies of diabetic and other types of polyneuropathy.

摘要:

The evaluation of dementia for reversible causes should not be overlooked. Hypothyroidism is a reversible cause for dementia. Mental status is one of the important factors to be assessed prospectively to determine whether a patient is likely to benefit from intensive inpatient rehabilitation. Because of the negative effect of dementia on the learning process during intensive inpatient medical rehabilitation, it alone may be a sufficient reason to consider alternatives to intensive inpatient rehabilitation. On our rehabilitation unit, hypothyroidism causing confusion was recognized and corrected in two patients. The thyroidstimulating hormone test is suggested as a screening tool.

摘要:

The biomechanical effect of functional loading was studied in surgically tenotomized, repaired and immobilized right Achilles tendons of 34 rabbits. Beginning from the 5th day after surgery, loading was initiated by removing the immobilization casts of the animals to permit unrestricted weight-bearing to tolerance. At each of 12, 18 and 21 days after surgery, functionally loaded tendons and their corresponding nonloaded controls were excised and compared for differences in tensile strength, tensile stress and energy absorption capacity. Functional loading induced a twofold increase in the tensile strength (P<0.05) and energy absorption capacity (P<0.05) of the tendons, at both 12 and 18 days after surgery. No statistically significant differences were observed in the tensile strength and energy absorption capacity of the tendons at 21 days after surgery. Statistically significant differences in tensile stress were not observed at any time period throughout the study. These findings demonstrate that functional loading augments the tensile strength and energy absorption capacity of experimentally tenotomized tendons without promoting re-rupture, but only during the very early stages of healing. Even though the healing process of rabbit tendons may differ from healing of human tendons, these results suggest that similar beneficial effects may be attained if repaired human Achilles tendon ruptures are carefully loaded during the very early rather than later stages of healing.

摘要:

The modification of a new design in orthosis usually has its clinical indication. In this study, a low-temperature thermoplastic ankle foot orthosis (AFO) was designed in anterior leaf type, called anterior AFO, to meet the need of indoor barefoot walking in Taiwan. It could be easily molded and remolded to fit the foot, as well as to adjust the position of the foot and ankleSixty-eight patients with acute hemiplegia were fitted with this anterior AFO during ambulation training: 46 had good fitting (67.6%), 15 had fair fitting (22.1%) and 7 had poor fitting (10.3%). Two patients were observed to have ankle clonus, and four patients experienced breakage or tear of the AFO within 4 wk.The gait characteristics were measured in six chronic hemiplegia patients to compare the effect of anterior AFO with posterior AFO (Teufel style). Their gait pattern did improve by AFO fitting, especially from the foot pressure distribution, but no significant difference between the two types of AFO was found.
