Kinesiology Final

Categorize the following Stance Subphases

Groups:

(a) Initial Contact

,

(b) Loading Responce

,

(c) Mid Stance

,

(d) Terminal Stance

• Left limb is performing
  terminal swing and initial
  contact

• End of a double-stance sub-phase

• Stance Limb is Vertical

• Contralateral LE is performing Initial Swing, mid-Swing, and Terminal Swing

• 3rd Sub-phase of Stance

• Heel Off

• Opposite limb (left) begins swing phase.
  Entire body weight on right (stance) limb

• Contralateral LE is performing Pre-Swing

• Second-= sub-phase of stance Phase

• First sub-phase of stance phase

• Body Weight begins to shift over stance limb, initiating first period of double stance

• Time during heel of stance limb rises from the floor

• Heel Strike

• Vertical displacement of the center of gravity is at its lowest

• Body weight begins moving away from
  stance (right) limb toward midline of body

• Contralateral LE is in terminal Stance

• Foot Flat

Forward propulsion of the body by the stance limb occurs in this subphase.

• Pre-Swing

• Terminal Stance

• Mid-Swing

• Mid-Stance

Categorize the following Swing Subphases

Groups:

(a) Initial Swing

,

(b) Mid-Swing

,

(c) Terminal Swing

• Deceleration of limb in prep for initial contact

• Finished advancement of swing limb

• 2ND Subphase of Swing

• Time during which swing LE begins advancing

• Acceleration

• Time which swing limb is in middle of swing

• First Subphase of Swing

Categorize Determinates of Gait

Groups:

(a) Lateral Pelvic Shift

,

(b) Lateral Pelvic Tilt

,

(c) Pelvic Rotation

• Horizontal movement where the pelvis rotates in the OPPOSITE direction of the swing LE

• Pelvis on the unsupported side falls lower
  than the pelvis on the supported side

• Most Pronounced during Mid-stance

• Lateral pelvic shift is a side-to-side movement of
  the pelvis to maintain COM over the stance LE

You are analyzing a patient pelvic rotation during gait. You would hope to see rotation of the pelvis (a)   direction of ​swing limb

• opposite
• The same
• no rotation at all
• backward rotation of the pelvis

Pelvic rotation during the swing phase of gait primarily serves to:

• • A. Stabilize the pelvis during weight transfer

• • B. Assist with hip flexion of the stance leg

• • C. Facilitate advancement of the swing leg and weight transfer onto the stance leg

• • D. Reduce stress on the knee joint of the stance leg

Knee flexion during mid-swing primarily functions to

• increase stability during standing
• reduce muscle fatigue in the thigh
• enhance balance while running
• clear the foot from the ground during walking.

The coordinated movements of the knee and ankle joint during gait primarily serve to

• Generate propulsion during the swing phase

• Absorb shock during heel strike

• Regulate the vertical displacement of the body's center of mass

• Maintain stability during the stance phase

What is the purpose of arm swing during the gait cycle

• Provides deceleration of LE

• To reduce the impact on the legs
• Maintain balance and improve walking efficiency by providing counterrotation of trunk.

• To increase the speed of walking

The ​ (a)   slow motion in terminal swing and prevent the knee from "snapping" into ​ (b)   just prior to initial contact.
