ABSTRACT
Objective To investigate walking ability of amputees with unilateral transtibial prosthesis. Methods From April to Decem-ber, 2016, 20 unilateral transtibial amputees (patients) and 20 healthy adults (controls) were tested with L test, balance test, 6-minute walk test (6MWT) and 1000 m walking outdoor on various terrain. Results There was no significant difference in time of L test between the am-putees wearing Solid Ankle Cushion Heel (SACH) and Storage Foot (t=0.675, P>0.05). In balance tests, there was no significant difference in the total track length, confidence ellipse area, maximum horizontal deviation and maximum vertical deviation between the patients and the controls (t0.05). Each parameter was significantly different in 6MWT between them (t>2.774, P4.130, P<0.001). Conclusion The walking ability of the unilateral transtibial ampu-tees wearing prostheses is different from normal people. The transtibial prosthetic feet that the amputees wear may impact their walking abil-ity.
ABSTRACT
Objective To systematically review the evaluation tools for walking ability of lower limb amputees wearing prostheses. Methods A computer-based search of PubMed, Wanfang Data and CNKI.net was performed for articles related to the evaluation of walking ability of lower limb amputees wearing prostheses published from January, 1995 to December, 2015. Results and Conclusion A total of 20 papers were selected, including 18 foreign literatures and 2 Chinese articles. There were many evaluation tools for walking ability of lower limb amputees wearing prostheses, and should be chosen according to the actual situation.
ABSTRACT
Objective To investigate the safety and efficacy of endoscopic multi-band mucosectomy (EMBM) in the treatment of early esophageal cancer and intraepithelial neoplasia.Methods A retrospective analysis was made on the clinical data of 34 cases diagnosed with early esophageal cancer and intraepithelial neoplasia.All the patients accepted EMBM.The therapeutic effects and safety were summarized.Results A total of 34 patients with 36 lesions were successfully completed in the treatment of one session.The entire biopsy specimen was tested by pathological examination.High-grade intraepithelial neoplasia in 24 lesions,low-grade intraepithelial neoplasia in 4 lesions,intramucosal cancer in 6 lesions,a submucosal shallow cancer and a submucosal deep cancer were diagnosed.Clamps electric coagulation hemostasis was used during the operation in 2 bleeding cases.No delayed postoperative bleeding,subcutaneous emphysema and esophageal perforation happened.Two cases appeared esophageal stenosis after EMBM.Bougienage were used to relieve dysphagia.One case confirmed with deep submucosal lymphovascular invasion accepted surgery later in department of thoracic surgery.No local recurrence and metastasis were found in the other 33 cases during the 6-24 months of follow-up time.Conclusions EMBM is a minimally invasive,safe and effective method for the treatment of early esophageal cancer and intraepithelial neoplasia.EMBM is worthy of promotion.
