ABSTRACT
Objective To quantify operation characteristics of the ankle rotating-traction-poking manipulation (RTPM) for treating acute lateral ankle sprain by using motion capture technology, so as to provide objective references for standardized operation of RTPM and its education inheritance. Methods A professional physiotherapist performed the RTPM on 60 volunteers with acute lateral ankle sprain. Motion capture system was used to acquire effective kinematic data during the RTPM, so as to make analysis and summarize rules. Results The average time of ankle rotating for six circles was 11.36 s and the average time of ankle traction and poking was 3.42 s. The average displacement of ankle traction was 36.94 mm and the average displacement of ankle poking was 22.44 mm. The average angle of ankle traction was 23.27°, and the average angle of ankle poking was 22.76°. During the RTPM for treating acute lateral ankle sprain, the average linear velocity of ankle rotating was 58.28 mm/s, and the average linear velocity of ankle traction and poking was 23.81 mm/s. The linear acceleration of ankle rotating was 0.43 mm/s2, and the linear acceleration of ankle traction and poking was 0.54 mm/s2. Conclusions The RTPM can be applied in clinical practice. During the RTMP, the principle of gentleness, rhythmicity and continuity should be followed. Under the premise of following physiological characteristics of ankle joint, treatment of the sprained ankle should be carried out with slow and uniform speed continuously.
ABSTRACT
Objective To observe the value of transvaginal color Doppler ultrasound (TVCDU) in the diagnosis of endo-metrial lesions.Methods All 246 patients suspected of endometrial diseases underwent TVCDU and transabdominal ultra-sonography.Ultrasonographic characteristics,especially the uterine endometrial thickness and blood flow distribution were observed,and the results were compared with surgery and pathological results.Results A total of 242 patients were pathologically diagnosed as endometrial diseases.TVCDU diagnosed 232 cases,with the diagnostic accordance rate of 95.87%.Transabdominal ultrasonography diagnosed 182 cases,with the diagnostic accordance rate of 75.21%.TVCDU was superior to transabdominal color Doppler examination (P<0.05).Conclusion TVCDU has high diagnosis accordance rate and can be used as routine examination of endometrial diseases.
