FOOT DURING GAIT

Question 1

what is the motion of the calcaneus in the frontal plane used as?

Answer 1

a gauge of STJ motion based on the vertical bisection of the calcaneus

Question 2

at the start of the contact phase how should the calcaneus be positioned?

Answer 2

slightly inverted indicating a supinated STJ

Question 3

during the contact period how should the STJ be?

Answer 3

pronating to absorb shock of heel contact

Question 4

during the midstance period how should the STJ be?

Answer 4

supinating and continue supinating though pr

*STJ should be in its neutral position before the end of midstance

Question 5

how is the foot affected during the propulsive gait?

Answer 5

patient will have a flexing of the MPJs during propulsion, blanching of the digits

Question 6

how is the foot affected during the apropulsive gait?

Answer 6

patient will not have flexing of the MPJs during the propulsion, lack of blanching of the digits

Question 7

how should the foot be assessed in the the transverse plane?

Answer 7

observed at toe off for an abductory twist

Question 8

what are some examples of conditions affected in the transverse plane? how should the MTJ be observed?

Answer 8

equinas
forefoot valgus

lateral border
forefoot will appear abducted if MTJ is in the pronated position

lateral aspect
forefoot will appear adducted on rearfoot giving a c-shape if MTJ supinated

Question 9

what should be observed in the sagittal plane?

Answer 9

MTJ should be observed for

midtarsal joint break

Question 10

what causes mid tarsal joint break?

Answer 10

rearfoot flexing over the forefoot due to loss of rigid lever

destabilization of the C-C joint

Question 11

what are the ideal conditions for gait analysis?

Answer 11

well lit area

unobstructed view of the patients head, shoulders, torso, hip, knees and feet
