Box plot of hamstring stretch reflex percentages in all testing conditions. The laboratory group consists of 16 participants 38.5 % while the arthroscopic group consists of 4 participants; 30 % before anaesthesia, 29 % after anaesthesia and 42 % with a direct pull. The low percentages represents the lack of reproducibility of the hamstring stretch reflex when used as an objective measure of knee functional stability
