ContextMedial tibial stress syndrome (MTSS) is an overuse injury occurring among the physically active. Linked to increased strain on the medial tendons of the ankle, studies emphasize controlling medial foot loading in the management of this condition. Kinesio taping (KT) has gained popularity for treating musculoskeletal pathologies; however, its effect on MTSS remains uninvestigated. This study aimed to determine if healthy participants and patients with current or previous history of MTSS differ in the rate of loading, and if KT affects plantar pressures in these participants.MethodsTwenty healthy participants and 20 participants with current or previous history of MTSS were recruited and walked across a plantar pressure mat prior to KT application, immediately after application, and after 24-h of continued use. Time-to-peak force was measured in 6 foot areas and compared across groups and conditions.ResultsANOVA revealed a significant interaction between group, condition, and foot area (F = 1.990, p = 0.033). MTSS participants presented with lower medial midfoot time-to-peak force before tape application (95%CI: 0.014–0.160%, p = 0.021) that significantly increased following tape application (p < 0.05).ConclusionsThese results suggest that KT decreases the rate of medial loading in MTSS patients. Future research might assess mechanisms by which this effect is achieved. 相似文献

Development of an In Vitro Model to Characterize the Effects of Transcatheter Aortic Valve on Coronary Artery Flow 下载免费PDF全文
Impairment of coronary artery flow, in either acute or chronic conditions, is a severe complication of transcatheter aortic valve (TAV) implantation, which can arise due to improper TAV positioning. However, little work has been done to quantify the effects of the TAV positioning on the coronary flow. In this study, a realistic in vitro model of coronary artery flow was developed and used to investigate the impact of TAV deployed orientations on coronary flow. The coronary hemodynamics was first replicated mathematically using a lumped parameter model with time‐varying myocardial resistance. Based on the analytical model, two stepper motor controlled stopcock valves were integrated in a left heart simulator to represent the variable myocardial resistance in the experimental setup. The coronary flow and pressure waveforms obtained from the in vitro system were consistent with published data. With a TAV deployed in different orientations, the measured results demonstrated that TAV orientation does not have a significant impact on the coronary flow. The developed in vitro model can be further utilized to simulate coronary flow under various pathological conditions. 相似文献

Conclusion: IBCT technique should be preferred owing to its high graft survival rate and ABG gain. While no significant difference was found in middle ear pressures between ears that underwent IBCT and normal ears, compliance values were found to be decreased in patients undergoing IBCT. However, the lack of correlation between ABG gain and compliance values indicated that compliance increase had no effect on post-operative ABG results. Objective: The aim of the present study was to compare tympanometric and audiological parameters in patients undergoing inlay butterfly cartilage tympanoplasty (IBCT) with their normal ears and to determine their difference with normal ear tympanometric parameters. Methods: Overall, 25 patients that underwent an operation between August 2010–May 2014 were included in the present study. In 13 of these patients, the ear that did not undergo operation was normal. 0.5, 1, 2, 4?kHz pure sound average values, tympanometric measurements and compliance values of normal and operated ears were compared. Results: The graft survival rate in patients was found to be 92%. Mean pre-operative air–bone gap (ABG) was 16.4?±?5.4 in patients, while mean post-operative ABG was 10.9?±?5.8, with a statistically significant difference (p?=?0.001) While there was no significant difference between operated and normal ears of patients in terms of middle ear pressure (0.441), compliance values were significantly higher in normal ears than those in operated ears (0.032). When post-operative ABG gain was compared with compliance values, no significant correlation was found between ABG gain and compliance measurements (r?=??0.025 and p?=?0.936). 相似文献

We reported a 30 years old man who suffered a bite wound of the right hand in a fight. Two days after
the injury, he was admitted in emergency because of stab wound above the head of the third metacarpal
bone. He presented the swelling, redness, pain and fever. Primary revision confirmed only partial lesion of the extensor apparatus. During the following days, we recorded a deterioration of local findings and magnetic resonance imaging revealed osteomyelitis and septic arthritis of the third metacarpophalangeal joint. The wound was then revised several times using negative pressure wound therapy in combination with intravenous antibiotics. After resolution of clinical and laboratory findings, the wound was finally closed by delayed primary suture. Clenched fist injury is a medical emergency that requires immediate surgical revision. We treated clenched fist injury with the development of septic arthritis and osteomyelitis with negative pressure wound therapy and obtained good outcomes. 相似文献

【摘要】目的:探讨负压球结合引流袋应用于骨科脊柱手术及关节置换术后引流效果及安全性,旨在探究适合骨科手术术后引流的最佳引流方法,提高患者术后恢复效果。方法:选取2014年2~8月来我院行脊柱手术和关节置换术的120例患者为研究对象,按照就诊先后顺序分为观察组和对照组,每组60例。术后观察组患者采用负压球联合引流袋引流法引流,对照组患者采用常规方法进行引流。观察并比较两组总引流量、持续引流时间、引流管更换次数和平均住院天数等指标;比较两组患者治疗有效率和患者满意度;同时比较两组患者发生感染、引流失血、神经血管损伤及关节肿胀等并发症情况。结果:(1)观察组患者总引流量、持续引流时间、引流管更换次数和平均住院天数等指标均优于对照组,差异具有统计学意义(P<0.05);(2)观察组治疗总有效率为96.67%(58/60),较对照组83.33%(50/60)偏高,差异具有统计学意义(P<0.05);(3)相比于对照组并发症总发生率20.00%(12/60),观察组患者出现感染、引流失血等并发症概率为6.67%(4/60),远偏低,差异也具有统计学意义(P<0.05)。结论:负压球联合引流袋应用于骨科脊柱手术及关节置换术后引流效果较常规引流方法效果好,其安全性也较高。 相似文献
