Kines. Jeopardy 2 Flashcards
Plane of motion in which ankle inversion/eversion occurs
Frontal Plane
What ligament resists Inversion, DF & Abduction?
Posterior talofibular
Anterior deviation from the M/L axis introduces this motion
Inversion/Eversion
The 2 major arches of the foot
Longitudinal and Transverse arches
The 2 anatomic joints of the transverse tarsal joints
The Calcaneocuboidal and the talonavicular
This tissue is crucial for maintaining SLS (Single-Leg support) stability
Hip Abductors (namely the Gluteus Medius)
Greatest vertical displacement occurs during
Single-Leg Stance
What do the following have in common?
Weight Acceptance
Single Limb Support
Swing Limb Advancement
Functional Tasks of Gait
Initial contact on stance limb to opposite limb toe-off
Loading response
What creates knee extension during midstance
Plantar Flexion / Hip Extension couple
This is the largest contributor to cervical spine lateral flexion
Intracervical
Oriented near sagittal plane
(in the spine)
Lumbar facet joints
Lower cervical extension & upper cervical flexion
Cervical Spine Retraction
IV disc do not exist here
AA & Sacral Joints (and arguably OA, but the slides don’t say that)
This osteokinematic motion pushes IV disc posterior
Spinal Flexion
Force coming in laterally to the leg is what type of force?
Valgus
What structure resists valgus force in the knee?
Medial Collateral Ligament of the Knee
What ligament becomes taught with anterior translation of the knee, while the tibia stays in place?
Posterior Cruciate Ligament (PCL)
What is the spinal abnormality when the spine moves either to the left or to the right in erect posture?
Scoliosis
What structures are at risk in forced inversion, caused by someone rolling their ankle
ATFL (Anterior Talofibular ligament)
CFL (Calcaneofibular ligament)
PTFL (Posterior Talofibular ligament)
What type of contraction is created as a result of a sitting overhead dumbbell press?
concentric middle deltoid contraction
What type of contraction occurs between the start and mid-phase, and what muscles control it?
Start- bent knee flexed hip
Mid- Full extension, jumping in the air
Concentric quads
Start → Mid at the Hip
Osteokinematic motion
Contraction Type
Muscle Responsible
Start- supine, knees bent on table, pre-bridging
mid- Supine, mid-bridging exercise
Extension of the hip, concentric Gluteus Maximus
