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.

Dynamic loads at knee joint of amputee are fundamental for rehabilitation of knee injury and prosthesis design. In this paper, a 3-D model for calculation of dynamic load at knee joint of trans-tibial amputee was developed. Gait analysis was done on three terrains including normal level walking, upstairs and downstairs. Dynamic loads at knee joint were calculated during one gait cycle. The results show that gait patterns and dynamic loads at knee joint were different among these three terrains. Although the general waveforms were about the same, the motion range of knee joint, ground reaction forces and loads at knee joint when walking upstairs or downstairs were larger than those in a normal level walking. The quantitative findings provide the theoretical basis of gait analysis and prosthesis design for trans-tibial amputee.

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.

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.

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.

OBJECTIVETo discuss the method of functional reconstruction of ischemic contracture in the lower limb and propose a classification protocol for ischemic contracture in the lower limb based on its severity and prognosis.

METHODSA total of 42 patients with ischemic contracture in the lower limb were included in this study. According to different types of disturbance and degrees of severity, surgical reconstructions consisting of nerve decompression, tendon lengthening or transfer, intrinsic foot muscle release and sural-tibial nerve anastomosis were performed in every patient.

RESULTSPostoperatively, all patients were able to walk on flat ground. Drop foot was corrected in 10 patients, and 5 patients still felt some difficulty during stair activity. Split Achilles tendon transfer to flexor hallucis longus tendon was performed in 12 patients, and their walking stability was improved. Seven patients accepted ipsilateral sural-tibial nerve anastomosis, and sensitivity recovery reached to S2 in 2 patients and S3 in 5 patients.

CONCLUSIONSIschemic contracture in the lower limb is a devastating complication after lower limb trauma. The prevention of contracture is much more important than the treatment of an established contracture. Split Achilles tendon transfer to flexor hallucis longus tendon and sural-tibial nerve anastomosis, which was initially implemented by us, could improve the functional recovery of ischemic contracture in lower limbs, and thus provides a new alternative for functional reconstruction of ischemic contracture in the lower limb.
