Subjective: See MOI and subjective clues for same such as stopping suddenly, running downhil, location, Hx of injury, many patients will not make the link between deceleration and mention that they feel it is during acceleration or sprinting. Important to have an understanding of patients load (demands of sports and position specific demands e.g. high speed running, jumping, kicking, etc, high volume of games, training, psych load) vs current capacity (pre season, off season, in season).
