Inferences about change-points in rehabilitation on the outcome of a knee arthroscopy as a results of patello femoral pain syndrome in sport

[摘要] English: Rehabilitation is recognized as a critical component in the treatment of sports injuries,and has been the subject of intense research over the past decade. As a result, soundscientific principles have been applied to the realm of rehabilitation data and results. Lifein the world as we know it is fast becoming a flustering playground that also affectsrehabilitation as such, and especially the cost and time of the rehabilitation programsprescribed. By developing ways to minimize time-consuming efforts and at the sametime optimize the efficiency of a rehabilitation program, we will be able to keep up withour constant changing world.As a result of the aforementioned, significant evidence has been found for a Change-Point model using rehabilitation data. A statistical method for analyzing rehabilitationdata/sequences containing a Change-Point is therefore proposed. The methods may beextended in many directions. By calculating a patients' Change-Point during hisrehabilitation process, one will be able to either take a more aggressive, or a moreconservative approach when adjusting the exercise prescription of a patient during thedifferent phases of the rehabilitation process. Evidence suggests that Change-Pointanalysis may be a completely new direction in rehabilitation as we know it.In order to implement the use of Change-Point analysis on rehabilitation data, one needsto identify an injury(s) along with the treatment used for it. Patello Femoral disorders,especially the Patello Femoral Pain Syndrome (PFPS) is a well-known problem in allage groups. This disorder is a very common complaint amongst the general population.Conservative treatment will always be the first option with regard to rehabilitation of thisdisorder. If, however, this method fails, the surgeon will opt for a surgical procedure, inthis case a procedure known as and arthroscopy. An arthroscopy is a minimally invasivesurgical procedure that can be performed for the purpose of diagnosing and the followingtreatment of problems within the internal structure of joints. Over the past decade, it hasbecome one of the most frequently used procedures for the diagnosis and treatment ofknee injuries.In addition, various rehabilitation or treatment modalities are proposed after a patientunderwent a knee arthroscopy. One of these modalities is isokinetic exercise. Isokineticexercise is a popular dimension in the field of resistive exercise and muscle evaluation. Itis made possible by an electro-mechanical device that keeps limb motion at a constant,predetermined velocity. Many competitive and recreational athletes perform resistancetraining as a part of their conditioning program. Resistance training in addition toincreasing muscular strength and hypertrophy may also aid in the prevention of injuries.Research indicates that resistance training promotes growth and/or increases in thestrength of ligaments, tendons, tendon to hone and ligament to bone junction strength,joint cartilage and the connective tissue sheaths within muscle. Studies involvinghumans and animal models also demonstrate resistance training can cause increased bonemineral content and therefore may aid in the prevention of skeletal injuries.Change-Point analysis can therefore be of high value to the Biokineticist in helpinghim/her to evaluate the progress of rehabilitation more successfully. Because of ourrapid changing world, it is imperative that new methods of analyzing and interpretingrehabilitation data are developed and created. This will aid in our understanding thereofand it will have a significant effect on the cost, time and outcome of a prescribed,rehabilitation program. Only then, will we as Biokineticists truly fulfill the mission ofour profession, which is to improve the quality of life of our fellow human beings.
