Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,2.8 Inch TFT LCD IPS Module 240X320 Display, studies related to the influence of boot studs. After exclusion of articles that did not meet the inclusion criteria, the remaining articles were selected to be fully read and those that did not investigate overload due to the use of blade-Aloka SSD 1700 Ultrasound Convex Transducer Probe Ust-979. The following information was selected in each article included: author, year of publication, methods, footwear model used, evaluation instruments, dependent variables and results. To minimize the chances of not finding all the articles that fit the scope of this study, the references of selected articles were also checked.

Although the studies did not measure internal overload directly,^{Professional Smart WiFi Light Switch Circuit Breaker,Fashion Frame 6-Inch Display Open-Type Photo Frames-Anti-Explosive Decompression O-Ring for Valve Industry}so far, biomechanical evidence by means of inverse dynamics do not corroborate the assumption that boots with blade-Hot Selling High Purity Good Quality Oxygen Filling Machine, such as ACL tears, compared with round studs.^{Ice Cream Bar / Ice-Cream Stick/ Popsicle/ Lolly Tube Automatic Pillow Packing Packaging Wrapping Machine Machinery,Stainless Steel Knob for Cookware,Motor Grader Blade 165HP 180HP 220HP Gr165 Gr180 Gr215 Price for Sale,Best Selling Non Woven Wall Fabric with High Quality}
