Clinical case: We report the case of a 92-year-old quadriparetic patient who suddenly presented a major swallowing disorder following trauma to the neck. A diagnosis of myasthenia gravis was suggested by single-fibre EMG of the extensor digitorum communis muscle. In view of the continued absence of dysphagia after 6 months of pyridostigmine treatment, this diagnosis was considered as definitive. Discussion: We review the various characteristics of myasthenia gravis and ways of investigating dysphagia. Conclusion: It is important to be aware of and investigate all the direct and indirect signs of dysphagia and establish the exact aetiology, in order to provide the best possible treatment. [less ▲]

In this study, we have investigated the influence of the installation on the dynamometer and of the mode of contraction used during a rotator cuff muscle training. 24 subjects were divided into 3 groups. Two groups of 8 subjects performed a training of the Internal Rotators (IR) in concentric mode (60°/s and 240°/s) and of the External Rotators in eccentric mode (60°/s). The first group was trained at 45° of abduction; the second was trained at 90° of abduction. The third group did not perform any shoulder training. All patients were assessed thanks to the isokinetic device ((3) x 60°/s concentric – (5) x 240°/s concentric – (4) x 60°/s eccentric) before and after training. Only the group trained at 45° of abduction increased the isokinetic maximal peak torque (+ p) in concentric mode during the second isokinetic assessment. No subject showed improvement through the eccentric exercise. They also improved the throw of the ball (+ 8.5 %). Possible feeling of discomfort and signs of subacromial conflict explained that no progression was recorded after training at 90° of abduction. Likewise, the eccentric mode would major the inhibition limiting the strength increase. Even if 90° of abduction seems more specific for assessment, 45° of abduction is more suitable for training.

CONTEXT: Despite the high rate of lower limb injuries in basketball players, studies of the dominant-limb effect in elite athletes often neglect injury history. OBJECTIVE: To determine lower limb explosive-strength asymmetries in professional basketball players compared with junior basketball players and control participants. DESIGN: Cohort study. SETTING: Academic medical institution. PATIENTS OR OTHER PARTICIPANTS: 15 professional basketball players, 10 junior basketball players, and 20 healthy men. MAIN OUTCOME MEASURE(S): We performed an isokinetic examination to evaluate the knee extensor (Ext) and flexor (Fl) concentric peak torque at 60 degrees .s(-1) and 240 degrees .s(-1) and (Fl only) eccentric peak torque at 30 degrees .s(-1) and 120 degrees .s(-1). Functional evaluation included countermovement jump, countermovement jump with arms, 10-m sprint, single-leg drop jump, and single-leg, 10-second continuous jumping. Variables were compared among groups using analysis of variance or a generalized linear mixed model for bilateral variables. RESULTS: The 2 groups of basketball players demonstrated better isokinetic and functional performances than the control group did. No differences in functional or relative isokinetic variables were noted between professional and junior basketball players. Professional players with a history of knee injury failed to reach normal knee extensor strength at 60 degrees .s(-1). Knee Ext (60 degrees .s(-1)) and Fl (eccentric 120 degrees .s(-1)) torque values as well as 10-second continuous jumping scores were higher in those professional players without a history of knee injury than those with such a history. Compared with the group without a history of knee injury, the group with a history of knee injury maintained leg asymmetry ratios greater than 10% for almost all isokinetic variables and more than 15% for unilateral functional variables. CONCLUSIONS: The relative isokinetic and functional performances of professional basketball players were similar to those of junior players, with no dominant-side effect. A history of knee injury in the professional athlete, however, was reflected in bilateral isokinetic and functional asymmetries and should be considered in future studies of explosive strength.

Introduction: Non-traumatic neuromuscular lesions of only one muscular portion of the quadriceps are rare and poorly described in literature. Aim: The goal of our study was to investigate the possible causes of this pathology and to objectively quantify the functional consequences of this isolated atrophy from the rectus femoris on the total muscular performances of the quadriceps. Patient and Method: A male patient, 44 years old, presented an isolated atrophy of the right rectus femoris without pain nor history of previous traumatic event. He reported occasional paraesthesias on anterior right thigh. Electromyographic exploration of the lower limbs, imagery (echography and MRI) and isokinetic test were undertaken by the patient. Results: Imagery explorations showed the atrophy of the right rectus femoris combined with fatty degeneration but this exam did not allow determining the actual etiology. Therefore, a precise diagnosis was not allowed, even if the EMG confirmed the presence of important signs of specific and isolated denervation only in the right rectus femoris. The isokinetic test, performed in the classical sitting position, highlighted symmetrical performances for flexors of the knee and a moderately decrease in the right concentric quadriceps torque (-10%). A complementary isokinetic assessment, in a lying supine position, demonstrated a more marked deficit of this right quadriceps (higher than -30%). Conclusion: No precise etiology was shown for this isolated atrophy of the right rectus femoris. Nevertheless, we brought back the importance to lay the patient in a lying supine position in order to preferentially investigate the rectus femoris performances through an isokinetic test. [less ▲]
