Quiz 3 Flashcards
% of stance, swing phase, double support
Stance phase = 60%
Swing phase = 40%
Double support = 10%
Walking cycle
-Heel strike
-Full foot
-Mid stance
-Heel off
-Toe off
-Acceleration
-Mid swing
-Deceleration
Factors that affect normal gait
-Weight
-Posture
-Fitness level
-Speed
-Gender
-Ground condition
-Footwear
-Clothing
Elements of normal gait
-Proper alignment
-Reciprocal arm swing
-Equal stride length
-Synchronized timing
-Vertical oscillations
-One leg goes forward, opposite arm goes forward
-Trunk and upper extremity rotate in opposite directions
-Stance should be longer than swing
Antalgic gait cause
Pain or discomfort in hip, knee, ankle or foot during weight bearing
Antalgic gait clinical findings
Decreased stance on affected side
If hip pain and no cane, where does the patient shift their weight and why?
The patient shifts weight over affected hip so that the hip is more vertical
Glute max gait cause
Weakness of glute max
Glute max gait clinical findings
-Thrust thorax posteriorly at initial contact to maintain hip extension of stance leg
-Characteristic lurch
Trendelenburg gait cause
-Weakness of glute med
-Unstable hip
Trendelenburg gait clinical findings
-Pelvis drops on opposite side
-Trunk lurches over stance leg
Slapping gait cause
Weakness in ankle dorsiflexion
Slapping gait clinical findings
-Patient lift leg higher than normal to clear foot
-Foot slaps ground at heel strike
Flaccid or hemiplegic gait cause
Cerebrovascular accident (stroke)
Flaccid or hemiplegic gait clinical findings
-Hip circumducts
-Arm held across body for balance
Arthrogenic gait cause
Decreased ROM in knee or hip joint
Arthrogenic gait clinical findings
-Increased plantarflexion
-Circumduction of hip
-Hip hikes
Ataxic gait cause
Cerebellar problem
Ataxic gait clinical findings
-Poor balance
-Wide base
-Jerky movements
-Weaving gait
-All movements exaggerated
-Foot slaps ground if sensory ataxia
Parkinson’s gait cause
Parkinson’s disease
Parkinson’s gait clinical findings
-Flexed neck, trunk, knees
-Short, shuffling steps
-Arms stiff
-Difficulty stopping and starting
Spastic or scissor gait cause
Spasticity of hip adductors (CNS disorder)
Spastic or scissor gait clinical findings
-Knees rub together
-Great effort required to bring legs foreward
Structures attached to medial meniscus
Medial collateral ligament
Semimembranosis
Transverse ligament
Coronary ligament
Structures attached to lateral meniscus
Anterior meniscofemoral ligament
Posterior meniscofemoral ligament
Popliteus
Transverse ligament
Coronary ligament
Functions of the meniscus
-Lubrication and joint nutrition
-Shock absorption
-Improves weight distribution
-Reduces friction
Knee capsular pattern
flexion, extension
Resting position
25 degrees flexion
What might a pop in the knee indicate?
Anterior cruciate ligament tear or osteochondral fracture
What causes locking in flexion?
Meniscus injury
What causes locking or catching momentarily in extension?
Loose body
Intracapsular swelling
Entire joint will be swollen, and knee assumes 15-25 degrees of flexion (will not be able to straighten knee in supine)
Extracapsular swelling
Localized
Valgus stress test (patient position, test action, positive response, indicates)
-Sitting with knee slightly flexed/almost straight
-Examiner stabilizes lateral femur and applies valgus stress to medial tibia (push lateral)
-Pain and/or laxity
-Indicates medial collateral ligament sprain/tear
