Because of the necessity of objective instrumental methods for assessing the state of skeletal musculature in patients with Duchenne muscular dystrophy, the aim of our work was to evaluate the correlation between manual methods of assessment of the muscle strength and the results of magnetic resonance imaging (MRI) of the skeletal muscles of lower limbs. We have examined 15 corticosteroid-naive patients with Duchenne muscular dystrophy. Patients were divided into 2 groups: ambulant patients (average age 8.1 years) and non-ambulant patients (mean age 12.7 years). Muscle strength of lower extremities of all patients has been evaluated by Medical Research Council scale and MRI of skeletal muscles of the pelvic girdle, thighs and lower legs has been performed. The following results have been obtained: ambulant patients have been characterized by a high correlation of MRC scale and MRI of the lower extremities in the evaluation of the pelvic girdle and thighs muscles and the total score (pelvic girdle, thighs and lower legs) and salient correlation in the evaluation of the lower legs muscles. Non-ambulant patients have been characterized by moderate correlation in the evaluation of pelvic girdle and thighs muscles, as well as the total score of lower limbs. There was no correlation between MRC and MRI results in the muscles of the lower legs. Magnetic resonance tomography is able to reliably estimate the degree of fatty infiltration in Duchenne muscular dystrophy and is the method of choice in the diagnosis and evaluation of the severity of this disease.

Penetration Aspiration Scale

Abstract Background: Prolonged mechanical ventilation is associated with muscle weakness, pharyngeal dysfunction, and symptomatic aspiration. The authors hypothesized that muscle strength measurements can be used to predict pharyngeal dysfunction (endoscopic evaluation–primary hypothesis), as well as symptomatic aspiration occurring during a 3-month follow-up period. Methods: Thirty long-term ventilated patients admitted in two intensive care units at Massachusetts General Hospital were included. The authors conducted a fiberoptic endoscopic evaluation of swallowing and measured muscle strength using medical research council score within 24 h of each fiberoptic endoscopic evaluation of swallowing. A medical research council score less than 48 was considered clinically meaningful muscle weakness. A retrospective chart review was conducted to identify symptomatic aspiration events. Results: Muscle weakness predicted pharyngeal dysfunction, defined as either valleculae and pyriform sinus residue scale of more than 1, or penetration aspiration scale of more than 1. Area under the curve of the receiver-operating curves for muscle strength (medical research council score) to predict pharyngeal, valleculae, and pyriform sinus residue scale of more than 1, penetration aspiration scale of more than 1, and symptomatic aspiration were 0.77 (95% CI, 0.63–0.97; P = 0.012), 0.79 (95% CI, 0.56–1; P = 0.02), and 0.74 (95% CI, 0.56–0.93; P = 0.02), respectively. Seventy percent of patients with muscle weakness showed symptomatic aspiration events. Muscle weakness was associated with an almost 10-fold increase in the symptomatic aspiration risk (odds ratio = 9.8; 95% CI, 1.6–60; P = 0.009). Conclusion: In critically ill patients, muscle weakness is an independent predictor of pharyngeal dysfunction and symptomatic aspiration. Manual muscle strength testing may help identify patients at risk of symptomatic aspiration.

Object In this study, the authors evaluated the efficacy of a new surgical strategy for reconnecting the injured brachial plexus with the spinal cord using fibrin glue containing acidic fibroblast growth factor as an adhesive and neurotrophic agent. Methods Eighteen patients with preganglionic brachial plexus injuries, each with varying degrees of upper limb dysfunction, underwent cervical laminectomy with or without sural nerve grafting. The treatment of each avulsed root varied according to the severity of the injury. Some patients also underwent a second-stage operation involving supraclavicular brachial plexus exploration for reconnection with the corresponding segment of cervical spinal cord at the trunk level. Muscle strength was graded both pre- and postoperatively with the British Medical Research Council scale, and the results were analyzed with the Friedman and Wilcoxon signed-rank tests. Results Muscle strength improvements were observed in 16 of the 18 patients after 24 months of follow-up. Significant improvements in mean muscle strength were observed in patients from all repair method groups at 12 and 24 months postoperatively (p < 0.05). Statistical significance was not reached in the groups with insufficient numbers of cases. Conclusions The authors' new surgical strategy yielded clinical improvement in muscle strength after preganglionic brachial plexus injury, such that nerve regeneration may have taken place. Reconnection of the brachial plexus to the cervical spinal cord is possible. Functional motor recovery, observed through increases in Medical Research Council–rated muscle strength in the affected arm, is likewise possible.

Muscle Groups

Differences between the two groups in terms of obtained muscle strength were measured. The Manual Muscle Test (MMT) of the Lovett, Medical Research Council was used before and after the experiment. The results showed that the majority of subjects showed greater improvement of muscle strength after using Thai musical instruments when compared to subjects in the traditional Akaboshi group. There were however, some drawbacks in the use of Thai instruments due to their size and weight. Some instruments were found to be unsuitable for certain muscle groups and some types of disabilities. The results of this small experiment support the hypothesis that Thai instruments could be used in lieu of those in the original Akaboshi methodology.

The aim of this report was to examine the safety of physical therapy for hemiplegia in a patient with neuromyelitis optica in the acute phase. A 32-year-old female with neuromyelitis optica diagnosed by magnetic resonance imaging had a T2-weighted hyperintense lesion in the central cord from C2 to T2 and was positive for serum anti-aquaporin-4 antibodies. Upon admission to the hospital, her Expanded Disability Status Scale, Medical Research Council scale for muscle strength score, and sensory score (according to the American Spinal Injury Association sensory assessment) were 9.0, 37, and 158, respectively. The patient commenced physical therapy on day 4. A locomotion exercise using an orthosis was started as soon as possible. Her left-side limb muscle strength improved to approximately grade 4 by a manual muscle test with improvements in the Expanded Disability Status Scale score (from 9.0 to 6.0), Medical Research Council scale for muscle strength score (from 37 to 54), sensory score (from 152 to 203), and all functional independence measure dominants compared with the respective values on admission. This report shows that a carefully supervised physical therapy program did not cause deterioration of the patient’s symptoms.

A avaliação da dispneia tem sido feita por meio de instrumentos como escala de Borg modificada, a escala de cores e a escala do Medical Research Council modificada (mMRC). O objetivo deste estudo foi correlacionar a frequência respiratória com a sensação de dispneia, através das escalas citadas, correlacioná-las entre si e verificar se o grau de alfabetização influenciou na resposta do paciente sobre a sensação de dispneia. Para avaliar o esforço físico utilizou-se o teste de caminhada de seis minutos. Este foi um estudo prospectivo, transversal e analítico-descritivo composto por 124 voluntários com diagnóstico de doença pulmonar. Para comparar as variáveis categóricas entre os grupos foram utilizados os testes Qui-Quadrado e exato de Fisher. Para comparar as variáveis contínuas foi utilizado o teste Kruskal-Wallis e para análise de correlação foi utilizado o coeficiente de correlação de Spearman. A idade média foi de 55,9 (± 13,08 anos), 14% eram analfabetos. Nos tempos de análise houve correlação positiva entre as escalas mMRC e Borg, r = 0,43, r = 0,61 e r = 0,55. Entre as escalas mMRC e Cores, observou-se correlação negativa. Concluiu-se que a frequência respiratória correlacionou-se com as três escalas. O grau de alfabetização não modificou a resposta do paciente em relação à sensação de dispneia.Palavras-chave: dispneia, fisioterapia, avaliação.
