Final answer:
Functional Movement Screen (FMS) relies on observations that assess proprioceptive feedback during specific movements to make recommendations. Without visual cues, this helps to determine issues such as cerebellar function impairment due to factors like alcohol consumption.
Step-by-step explanation:
FMS, which stands for Functional Movement Screen, relies on specific types of observations during movement patterns to make prescription recommendations. These observations focus primarily on proprioceptive feedback, which is the body's ability to perceive its own position in space without visual cues. For instance, a common exercise may include having a person extend their arms and touch their fingertips to their nose with their eyes closed. This activity removes visual feedback, making the person depend solely on proprioceptive signals to guide their movements. This type of observation checks how well the person can control and perceive their body's movements, which is essential in identifying dysfunctions or imbalances that may be improved through targeted exercise programs.
The use of proprioceptive feedback is particularly important as it provides information on how well a person's cerebellum—a brain region responsible for motor control—is functioning. Alcohol consumption can impact this region, which can be observed in the broad movements of the arms when an individual's visual feedback is removed. Moreover, effective observational skills are crucial for conducting these evaluations, allowing for accurate assessment of the patient's movements based upon verbal descriptions and without the influence of visual demonstration.
