SummaryElectromyography (EMG) measures muscle electricity. It depends on muscle contraction and central motor control. Muscles react very sensitive on external signals (e. g. bleeding), The resulting changes can be shown in EMG. Patients, methods A first study included 51 children and young adults from Costa Rica. They underwent a clinical examination and EMG of the hip, knee and ankle joints. Resting muscle tone, maximal isometric contraction and three typical isotonic movements of the joints were measured. First step of analysis was to characterize typical pathogenic changes in the muscles and to find a corresponding physical therapy to minimize these changes. Results It showed that EMG is a good marker for muscle condition. It helps to individualize therapy and improve effectivity of physical and physiotherapeutic treatment of the locomotive system of children and young adults with hemophilia. It can help to recognize early subclinical changes and to control the outcome of therapeutic modalities.

The purpose of the study was to investigate the effects of ankle angular position and standing surface type on static upright balance. Ten young adults stood on a force platform or on a firm wedge that induced 15° of either dorsiflexion or plantarflexion. In addition, a piece of foam was placed on top of the force platform and on the wedge. The center of pressure distance and velocity in the anteroposterior and mediolateral directions were calculated. Significantly larger magnitudes in most of the investigated variables were seen while standing with ankles in the dorsiflexion when compared with standing with the ankle joints in a natural position (p < .05). Plantarflexion increased the center of pressure anteroposterior velocity by 87% when compared with a natural stance (p < .05). Standing on the foam surfaces resulted in increases in all of the center of pressure measures by an average of 38% in all of the ankle conditions.

The Relationship

Category: Ankle Arthritis Introduction/Purpose: Takakura-Tanaka classification is effective as an X-ray evaluation method for determining the severity of and treatment strategy for ankle osteoarthritis (OA). Concerning OA, MRI is gaining attention as a tool for examining the condition of the articular cartilage over X-ray findings. However, there are few reports on the relationship between MRI and X- ray findings in ankle joints. We assessed MRI findings of ankle OA at each stage of Takakura-Tanaka classification to investigate the effects of bone and articular cartilage. Methods: We studied the localization of Bone Marrow Edema (BME) partitioned articular surface by MRI in 22 regions at the talocrural, talocalcaneal, talonavicular, and calcaneocuboid joints of 46 feet of 45 patients who had a diagnosis of ankle OA in our hospital. Furthermore, we compared the radiological findings with the localization of BME. Results: By MRI, the area where BME was seen is located in the anterior medial part of the talocrural joint. Pointedly, 60% of BME was confirmed on the tibial side of the talocrural joint. In addition, as the Takakura-Tanaka classification advanced, the identification of BME tended to increase on the anterior of the talus and the medial malleolus articular surface. Conclusion: We found on MRI that the localization of BME was identified by Takakura-Tanaka classification in osteoarthritis of the foot. On the other hand, there are some cases of OA without BME that were identified by X-ray in this study. In the future, there is a possibility that the severity of OA can be classified into more inclusive classifications by MRI. We intend to combine the severity of ankle OA with MRI findings and Takakura-Tanaka classification together.

Purpose Although guidelines have changed regarding federally mandated concussion practices since their inception, little is known regarding the implementation of such guidelines and the resultant continuum of care for youth athletes participating in recreational or organized sports who incur concussions. Furthermore, data regarding the role of speech-language pathologists in the historic postconcussion care are lacking. Therefore, the purpose of this retrospective study was to investigate the experiences of young adults with history of sports-related concussion as it related to injury reporting and received follow-up care. Method Participants included 13 young adults with history of at least one sports-related concussion across their life span. We implemented a mixed-methods design to collect both quantitative and qualitative information through structured interviews. Participants reported experiencing 42 concussions across the life span—26 subsequent to sports injuries. Results Twenty-three concussions were reported to a parent or medical professional, 14 resulted in a formal diagnosis, and participants received initial medical care for only 10 of the incidents and treatment or services on only two occasions. Participants reported concussions to an athletic trainer least frequently and to parents most frequently. Participants commented that previous experience with concussion reduced the need for seeking treatment or that they were unaware treatments or supports existed postconcussion. Only one concussion incident resulted in the care from a speech-language pathologist. Conclusion The results of the study reported herein shed light on the fidelity of sports-related concussion care management across time. Subsequently, we suggest guidelines related to continuum of care from injury to individualized therapy.
