Turning Flashcards
What are the 3 main turning strategies?
- Step Turn
- Spin Turn
- Ipsilateral Crossover
What limb is the one that initiates the turn?
The Reference limb is the limb that Always Initiates the turn
What is the reference limb in a step turn?
Outside leg
What is the reference limb in a spin turn?
Inside Leg
What is the reference limb in a Ipsilateral Crossover?
Inside Leg
What is the objective associated with a Step Turn for Loading Response?
Initiate change in Direction of COM
What are the Critical Events Associated with a Step Turn for Loading Response?
- Leg Rotation Towards Side (Internal Rotation)
- Beginning trunk and pelvic rotation towards turn side
- Slight foot supination
What is the objective associated with Step Turn for Mid stance?
Change direction of body COM
What are the critical events associated with a Step Turn for Mid Stance?
Continued Pelvis and Trunk Rotation (as a unit)
Slight Supination to Pronation as inside limb steps forward
What is the objective for Terminal Stance in a step turn
Complete change of direction of body COM
What are the critical events associated with Terminal stance in a step turn?
- Continued rotation of body and trunk towards new direction
- Relative LE external rotation as swing limb turns in new direction
- Foot Pronation
What is the objective for Pre-Swing in a Step Turn?
Re-Align body in new direction
What are the critical events for Pre-Swing in a Step Turn?
- Achieve forward position of body in new direction via loading response of contralateral limb
- Begin realignment of reference limb in new direction
What is the objective for Initial-Swing in a Step Turn?
Re-Align reference limb with body
What is the critical event associated with initial-swing in a step turn?
Slight Internal rotation of leg in neutral in line with pelvis
What is the objective for a spin turn in loading response?
Same as Normal Gait LR
What is the critical event(s) for a spin turn in Loading Response
Same as Normal Gait LR
What is the objective for Midstance in a Spin Turn?
Change Direction of body COM VIA a Pivot on Reference Foot
What is the critical event for Midstance in a Spin Turn?
Ankle PF and Slight supination
What is the Objective/Critical event for Terminal Stance in a spin turn?
Same as normal Gait Terminal Stance
What is the Objective/Critical event for Pre-Swing in a spin turn?
Same as normal Gait Pre-Swing
What is the objective associated with Ipsilateral Crossover for Loading Response?
Initiate Change in Direction of COM
What is the Critical Event Associated with Ipsilateral Crossover for Loading Response?
Leg Rotation Towards turn side (external Rotation)
What is the objective associated with Ipsilateral Crossover for Midstance?
Change in direction of COM
