Task 1 Movement Impairment Syndromes – Instructions

Movement impairment syndromes are caused by a series of malalignments and altered muscle recruitment by the CNS depending on posture, joint hypermobility or hypomobility, altered length tension, or force-couple relationships, etc. This activity is designed to help the student understand these syndromes and understand the musculature and physiology involved in producing these types of syndromes.

Activity 1-1 Describe an athletic population that might exhibit a forward head and rounded shoulders. Indicate why they would exhibit this posture and the musculature responsible for this malalignment.

______

Activity 1-2 Describe reciprocal inhibition and synergistic dominance and their potential for injury with regard to a long distance runner. The runner spends most of the day sitting at a desk job but runs 3-5 miles for daily exercise. What dysfunctions and potential types of injuries would you expect in this person?

______

Activity1-3 Have lab partners assess each other’s static posture and determine what movement impairment syndrome they exhibit. Write a summary of which of the two, or both, your lab partner exhibits as well as the musculature involved.

______

Task 2 Evidence-Based Review of Common Segmental Movement System Impairments –

Instructions

One of the most important aspects of the NASM Corrective Exercise coursework is the evidence-based nature of the system by which it is implemented. This task will give the student the opportunity to research the different kinetic chain segments that affect movement and impairment of movement.

Activity 2-1 Choose the foot and ankle, hip and knee, low back, or shoulder and write a summary report on three of the references associated with the static malalignments, abnormal muscle activation patterns, and dynamic malalignments of your chosen body segment. Written assignment should be no less than 1500 words in API style with proper grammar and punctuation.
