This chapter covers: How to develop static stability and movement dissociation and their assessment. How to use a variety of scoring systems to assess movement quality. The involvement of the cognitive component in closed Vs open skills, and how perturbating the visual, vestibular, and cognitive domains can provide a more effective rehabilitation. The different approaches of coaching movement skills and conceptual considerations on avoiding Vs gradually exposing ACL patients to movement commonly considered as 'dangerous'. How to progress from static exercises to landing tasks and the criteria which could be used. How to use hop tests and maximise the impact to the data from them for progression decision making.
