Stroke has the characteristics of high prevalence, high morbidity, and high mortality, which seriously affects life quality of patients and also creates a huge social burden. Telerehabilitation technology is on the basis of traditional rehabilitation equipment and it integrates with cloud computing and big data technologies. It provides a new way for rehabilitation by providing comprehensive rehabilitation technology and service based on the cloud platform. Therefore, it provides a solution for the situation that the rehabilitation medical resources and the rehabilitation talents in China are relatively insufficient. This article mainly discusses the telerehabilitation technologies of lower extremity motor dysfunction in patients with stroke, the problems and the future development direction.

The increase in the proportion of elderly people in the population is one of the most remarkable sociodemographic phenomena of the twenty-first century. The number of patients with diabetes is also increasing worldwide with this demographic change. Given these facts, consideration of the problems the general elderly population is facing in the management of diabetes is essential. In this review article, we focus on sarcopenia, which is the decrease in lower extremity muscle mass and muscle strength accompanying aging, describe the relationship between sarcopenia and diabetes, and highlight the specific factors through which diabetes contributes to loss of muscle strength. The quantitative methods for evaluating lower extremity muscle strength will also be described. These methods hold the key to assessing the effectiveness of exercise therapy and optimizing the assessment of the degree of autonomy in the activities of daily living. Exercise is one of the basic treatments for type 2 diabetes and may also prevent and improve sarcopenia. This review discusses the aspects common to the two health conditions and elucidates the effectiveness and necessity of exercise as a preventive measure against diabetes among the elderly.

Ebstein malformation is a congenital heart disease characterized pathologically by displacement of the septal leaflet of the tricuspid valve towards the apex of the right ventricle of the heart. Hypoplasia, dysfunction of the right ventricle and tricuspid regurgitation cause an increased volume load of the right heart and result in the clinical manifestations of chest tightness, shortness of breath and fatigue after activities, palpitation, cyanosis and heart failure. We report a case of Ebstein's anomaly with refractory right heart failure and leg ulcers.

PURPOSE: To examine the effects of conservative and surgical treatments for nocturnal leg cramps in patients with lumbar spinal stenosis (LSS). Nocturnal leg cramps is frequently observed in patients with peripheral neuropathy. However, there have been few reports on the relationship between nocturnal leg cramps and LSS, and it remains unknown whether conservative or surgical intervention has an impact on leg cramps in patients with LSS. MATERIALS AND METHODS: The subjects were 130 LSS patients with low back and leg pain. Conservative treatment such as exercise, medication, and epidural block was used in 66 patients and surgical treatment such as decompression or decompression and fusion was performed in 64 patients. Pain scores and frequency of nocturnal leg cramps were evaluated based on self-reported questionnaires completed before and 3 months after treatment. RESULTS: The severity of low back and leg pain was higher and the incidence of nocturnal leg cramps was significantly higher before treatment in the surgically treated group compared with the conservatively treated group. Pain scores improved in both groups after the intervention. The incidence of nocturnal leg cramps was significantly improved by surgical treatment (p=0.027), but not by conservative treatment (p=0.122). CONCLUSION: The findings of this prospective study indicate that the prevalence of nocturnal leg cramps is associated with LSS and severity of symptoms. Pain symptoms were improved by conservative or surgical treatment, but only surgery improved nocturnal leg cramps in patients with LSS. Thus, these results indicate that the prevalence of nocturnal leg cramps is associated with spinal nerve compression by LSS.

OBJECTIVE: To investigate the characteristics of forensic clinical identification on common peroneal nerve injury in traffic accident. METHODS: Eight cases of common peroneal nerve injury in traffic accidents were analyzed, including general condition of the wounded, the way of injury, the imaging results, the EMG results, and the degree of injury, etc. RESULTS: In 8 cases, 2 cases of complete common peroneal nerve injury were determined to grade 9 (disability degree) and 6 cases of partial common peroneal nerve injury were determined to grade 10 (disability degree). CONCLUSION By comparison, the disability degree of complete common peroneal nerve injury is higher than that of partial common peroneal nerve injury. The forensic clinical identification of common peroneal nerve should be made with synthetical consideration of medical history, symptoms, and auxiliary examinations.

BACKGROUNDHypotension due to the induction of sedation with dexmedetomidine infusion may be harmful in critically ill patients. Changes in pulse pressure induced by the passive leg raising test (PLR-ΔPP) as marker of fluid responsiveness, assessed prior to sedation, may predict hemodynamic changes. The present study was to investigate the power of the PLR test in critically ill patients in predicting hypotension induced by the induction of dexmedetomidine sedation.

METHODSFluid responsiveness was estimated by a passive leg raising (PLR) test before dexmedetomidine sedation. Patients were assigned to either the "Nonresponders" or "Responders" group according to their hemodynamic responses to the PLR test ("Nonresponders", PLR-ΔPP < 10.3%; "Responders", PLR-ΔPP ≥ 10.3%). Sedation was performed with a dexmedetomidine infusion (0.5 µg/kg over a 10-minute loading period, then 0.2 - 0.7 µg×kg(-1)×h(-1)) and titrated to maintain the target Richmond agitation sedation scale (RASS) score in the range of -2 to -1 and the bispectral index value in the range of 60 to 75. Radial artery pulse pressure, heart rate (HR), and central venous pressure (CVP) were measured at each phase of the study procedure. Hemodynamic fluctuations during the use of dexmedetomidine sedation were recorded and compared between the two groups.

RESULTSFifty patients had a median (25% - 75% interquartile range) of 71 (61 - 78) years old were studied. At baseline, 39 of the 50 patients were "Nonresponders" and 11 were "Responders". Following dexmedetomidine sedation, patients classified as "Responders" had a significantly greater systolic blood pressure decrease during the induction of dexmedetomidine sedation than the "Nonresponders" ((-26.3 ± 6.8)% vs. -11.8 ± 8.5)%, P < 0.001). In addition, the "Responders" group required significantly more fluid boluses (8 vs. 3; P < 0.001) and vasopressors (2 vs. 0; P < 0.05) than the "Nonresponders" group to restore blood pressure. Finally, PLR-ΔPP was positively correlated with changes in systolic blood pressure (PLR-ΔSBP) (r(2) = 0.576; P < 0.001) and significantly correlated with dexmedetomidine infusion-induced changes in SBP (r(2) = 0.202; P < 0.05). AUC for PLR-ΔPP was 0.84 (95%CI 0.71 - 0.93). PLR-ΔPP predicted hypotension with a sensitivity of 73% and a specificity of 92%.

CONCLUSIONSThe fluid responsiveness assessment pre-sedation was found to predict blood pressure fluctuation during the induction of dexmedetomidine sedation. The PLR test conducted prior to sedation may be a useful tool to identify patients with a high risk of hemodynamic events and may be used to indicate the need for prophylactic treatment.

Compartment syndrome of the thigh is a rare condition, potentially resulting in devastating functional outcome. Increasing intracompartmental pressure which suppresses microcirculation and capillary perfusion may lead to cellular anoxia and muscle ischemia. The muscle compartments in the thigh have a more compliant fascia and blend anatomically into the open compartments of the pelvis, thus compensating higher volumes than the compartments in the lower leg. We present a previously unreported case in which the limb of a 36-year-old man was run over by a 25-ton truck. He presented with a sensomotor deficit in his left lower leg with full paralysis of the shank muscles and absence of all foot pulses. CT scan showed a huge haematoma in the thigh with active bleeding out of the popliteal artery into the haematoma which has already expanded into the muscle compartments of the lower leg. The limb had a disastrous compartment syndrome of the thigh and lower leg with disruption of the popliteal neurovascular bundle; however, no bones in the limb were fractured. A complete fasciotomy of all the lower limb muscle compartments was immediately performed. The artery was reconstructed with interposition of the smaller saphenous vein, which was already interrupted through the initial trauma.

OBJECTIVETo investigate the efficacy and safety of combined common femoral artery (CFA) endarterectomy with superficial femoral artery (SFA) stenting plus Shuxuening Injection infusion in patients with complex multifocal arterial steno-obstructive lesions of the lower extremities.

METHODSFrom March 2006 to March 2011, 104 lower limbs in 96 patients with multilevel peripheral arterial steno-occlusive disease, involving SFA as well as CFA and deep femoral artery (DFA) orifice, were treated by combined surgical with endovascular therapy, such as SFA stenting as an adjunct to CFA endarterectomy and patch angioplasty with the great saphenous vein. Before the end of the operation, 20 mL of Shuxuening Injection was infused through the catheter located in the treated artery. Technical and hemodynamic success, as well as primary and primary-assisted patency, was determined according to the Society for Vascular Surgery Guidelines. During follow-up, clinical status assessment, ankle-brachial index (ABI) test, and duplex Doppler ultrasound were administered every 6 months, and computed tomography angiography or magnetic resonance angiography was performed at 12, 24, and 36 months after discharge.

RESULTSAll patients underwent successful combined CFA endarterectomy with SFA stenting treatment. The average ABI after the combination treatment increased from pretreatment of 0.32±0.21 to 0.82±0.24 (P<0.01). No perioperative death and major limb amputations occurred. The mean duration of follow-up for 104 limbs from 96 patients was 1,180 days (range, 196-2,064 days). During follow-up, 5 patients died due to myocardial infarction, cerebral infarction, or pneumonia, and 5 patients were lost to follow-up. There were 21 cases (21.4%) of restenosis, with 15 that occurred in-stent and 6 near the distal end of the stent. A total of 18 (18.3%) reinterventions were performed, including 6 balloon angioplasty, 8 restenting procedures, 2 bypass surgeries, and 2 major limb amputations. The primary patency rates were 92.2%, 76.8%, and 61.3% at 12, 24, and 36 months, respectively, while the primary-assisted patency rates were 94.4%, 83.2%, and 75.6% at 12, 24, and 36 months, respectively.

CONCLUSIONThe combined CFA endarterectomy with SFA stenting plus Shuxuening Injection infusion appears to offer a safe, less invasive, and effective treatment option to patients with chronic lower extremity ischemia due to complex multifocal peripheral artery disease.
