Biến giá trị tiền xử lý thay đổi có thể có trong gân đường kính từ 0,5 và 1,0 mm so với thay đổi giá trị tiền xử lý dứt khoát thay đổi trong mô hình siêu âm gân; paratendinous chất lỏng. và sự khác biệt của đường kính gân anteroposterior (AP) được đánh giá là mô tả trong Bảng . | Materials and Methods 9 Fig. a Skin erosion after low-energy SWA. b Skin erosion after high-energy SWA. a b The sonographic evaluation was not solely based on the measurement of the tendon diameter but on a semiquantitative scale evaluating tendon function during flexion extension of the ankle. This was studied intraindividually and morphological changes Table Semiquantitative rating of sonographic tendon changes Rating Criteria 0 No change Variation in tendon diameter of less than mm compared to pretreatment value I Possible changes Variation in tendon diameter between and mm compared to pretreatment value II Definitive changes Changes in tendon ultrasound pattern paratendinous fluid. Variation in tendon diameter of more than mm compared to pretreatment value and discrepancies of the anteroposterior A-P tendon diameter were rated as described in Table . The rabbits were killed by intravenous administration of xylazine ketamine and thiopental. Specimens were taken immediately after the death of the animals and fixed in 4 paraformaldehyde Table . Further processing was performed in a routine fashion at the university s Institute of Pathology. 5 J m paraffin sections were stained using haematoxylin-eosin HE and Alcian blue. A qualitative and semiquantitative assessment of the sections was performed by a pathologist without knowledge of the treatment group according to the proposals of Backman et al. 1990 thus grading staining affinity nuclear appearance and fibrillar appearance of the tendon on a four-step scale from no change to marked change as well as thickness degree of fibrosis degree of edema capillary changes and degree of inflammatory response of the paratenon. 10 2 Dose-Dependent Effects of Extracorporeal Shock waves on Rabbit Achilles Tendon Results Throughout the experimental period the animals were in generally good condition. No immobilization was used. Clinically there was no sign of muscular or neurological dysfunction in
