The player to receive has to decide whether to play until 9th or until 10th point. We observe in this paper that the score of the squash game can be modelled as a Markov chain. Thus using standard techniques of Markov processes, we can derive the optimal strategy for the squa...

BACKGROUND Reinjury rates after anterior cruciate ligament reconstruction (ACLR) are highest among young athletes, who consequently suffer from low rates of return to play. Historically, quantitative measures have been used to determine readiness to return to sport; however, they do not assess modifiable risk factors related to the quality of movement. PURPOSE To determine the effectiveness o...
