Neuromuscular activity in the golf swing with implications for the practice and in the prevention of overuse injuries
The aim of the study is to reduce the gap between scientific modelling of biomechanical and kinesiological approaches, and the nature of prevalence in golf related injuries. This project merges the description of the golf swing, combining EMG, kinematic and kinetic analysis, with questionnaires and functional assessment methods.
The objective of this series of studies is to correlate movement characteristics of the golf swing with golf specific functional evaluation and practice related variables, in such a way that they will provide a basis for understanding the prevalence of golf related injury, as well as the enhancement of health status and performance. The justification and interest of this project lies at a scientific and innovative level, and at the outputs for the community of golf (golfers, coaches, therapists, etc.).
he project implies three major tasks: the Identification of injury risk factors in golf, movement analysis of the golf swing, and finally the analysis of reciprocal influence between golf practice and low back pain. The dependent variables we will control can be grouped in this way: A. Identification of injury risk factors in golf a. Players profile variables i. Personal data ii. Morphological variables iii. Level of practice iv. Training practice v. Carrying load b. Epidemiological variables in golf i. Anatomical distribution of injuries ii. Nature of injuries (trauma/overuse) iii. Duration of symptoms iv. Impact (loss of playing time) v. Nature of sport injury (golf related or not) vi. Point prevalence (single/multiple) vii. Hospitalization and medical treatment B. Movement analysis of the golf swing a. Neuromuscular activations patterns using EMG analysis i. Timing parameters: onset, time of activation peak, duration ii. Sequential activation timing parameters iii. Intensity parameters: % MVC b. Kinematic variables using three dimensional high-speed motion analysis, accelerometer and “radar” i. Absolute and relative duration of swing phases ii. Time of club head acceleration peak iii. Articular range of motion, X and crunch factors iv. Initial ball speed c. Kinetic variables i. Analysis of the stance using foot pressure platforms ii. Analysis of grip pressure C. Analysis of reciprocal influence between golf practice and low back pain a. Health status measures for low back pain i. Questionnaire (Roland-Morris disability questionnaire – RMDQ; Short form McGill pain questionnaire SPM-PQ) b. Functional assessment of low back function i. Clinical tests (Back pain monitor) c. Neuromuscular activations patterns using EMG analysis (trunk) i. Timing parameters: onset, time of peak of activation, duration ii. Sequential activation timing parameters iii. Intensity parameters: percentage of the EMG of the MVC d. Kinematic variables using motion analysis i. Absolute and relative duration of swing phases ii. Time of club head acceleration peak iii. Articular range of motion, X and crunch factors iv. Initial ball speed e. Kinetic variables i. Analysis of the stance using foot pressure platforms ii. Analysis of grip pressure
