Chapter 12: Posture, Movement and Performance Assessment Flashcards
Static posture
The positioning of the musculoskeletal system while the body is motionless.
Dynamic posture
Alignment of the body while in motion.
Optimal movement
Moving in a biomechanically efficient manner that maximizes muscle recruitment and minimizes risk of injury.
Movement impairments
Abnormal movement patterns that can indicate possible muscle imbalances or mobility limitation.
Movement assessment
An assessment of a client’s movement patterns and postural alignment during movement or activity; also known as a dynamic postural assessment.
Muscle imbalance
When muscles on each side of a joint have altered length-tension relationships.
Mobility
Optimal flexibility and joint range of motion; ability to move freely.
Performance assessment
Assessments used to measure overall strength, muscular endurance, power, and agility.
Pes planus
Collapsed arch of the foot; also known as flat feet
Overactive
When elevated neural drive causes a muscle to be held in a chronic state of contraction.
Underactive
When a muscle is experiencing neural inhibition and limited neuromuscular recruitment.
Static postural assessment
An assessment that provides insight to deviations from optimal alignment of the body in a standing posture.
Anterior
On the front of the body.
Posterior
On the back of the body.
Kinetic chain checkpoints
The five areas of the body that are monitored during movement assessments and exercise: foot/ankle, knees, lumbo-pelvic-hip complex, shoulders, and head.
Anterior pelvic tilt
An excessive forward rotation of the pelvis that results in greater lumbar lordosis.
Knee valgus
Knees collapse inward (knock knees) due to hip adduction and internal rotation; also known as medial knee displacement and genu valgum
Knee varus
Knees bow outward (bowlegged); also known as genu varum.
Pes Plans distortion syndrome
Postural syndrome characterized by flat feet, knee valgus, and adducted and internally rotated hips.
Lower crossed syndrome
Postural syndrome characterized by anterior pelvic tilt and excessive lordosis of the lumbar spine.
Lordotic/Lordosis
The normal curvature of the cervical and lumbar spine regions, creating a concave portion of the spine
Upper crossed syndrome
Postural syndrome characterized by a forward head and protracted shoulders.
Overhead squat assessment (OHSA)
A movement assessment designed to assess dynamic posture, core stability, and neuromuscular control of the whole body during a squatting motion.
Single leg squat assessment
A movement assessment that assesses dynamic posture, lower-extremity strength, balance, and overall coordination in a single-limb stance.
