Q

Describe the lateral step dow test

A
  • 7 point scale: 0-1 = Good and 2+ = Moderate
  • 15cm step: 60º knee flexion and relationship to DF
17
Q

Is the ankle-foot complex in supination or pronation during each phase of stance

A
  • Initial contact: supination
  • Loading response: rapid conversion to pronation
  • Terminal stance: return to supination (rigid lever) for propulsion at terminal stance
18
Q

How to identify rear foot and forefoot positioning

A
  • Measured in non-weight bearing and prone
  • Establish subtalar joint neutral (STJN) position by palpation b/w thumb and index for when the talus is felt equally on both sides
  • Measure calcanea inversion or eversion by a line that bisects the leg vs that of the calcaneus
  • Calcaneal INV = rearfoot varus
  • Calcaneal EV = rearfoot valgus
  • Slight rearfoot varus of 2-4º is normal
19
Q

What is forefoot varus

A
  • In non-weight bearing think more of inversion & supination
20
Q

Describe uncompensated versus compensated forefront varus

A
  • Uncompensated: The rearfoot is rigid and cannot compensate. Instead of subtalar joint compensation, it will have to try to take place in the midtarsal joint
  • Compensated: When the degree of forefoot varus is equal to or less than the degree of calcaneal eversion.
21
Q

Conditions associated with a compensated forefoot varus

A
  • Halux valgus
  • Posterior tendon tendinitis
22
Q

What is forefoot valgus

A
  • Eversion position relative to the calcaneus
  • Measure in STJN non-weight bearing prone position
23
Q

Describe a flexible forefoot valgus

A
  • There is sufficient flexibility in the midtarsal joint to allow the lateral column of the foot to reach the supportive surface during the stance phase of gait. The heel may function perpendicularly, but the amount of compensation that occurs leads to an unstable gait with late pronation through midstance into propulsion.
24
Q

Describe a rigid forefoot valgus

A
  • When the range of motion in the mid-tarsal joint is not enough to allow the lateral column of the foot to touch the ground, rearfoot supination/compensation is required. This is rarely seen clinically.
25
Q

Describe the foot posture index (FPI-6)

A
  • Talar head position: POS = palpate medial
  • Curves above & below lateral malleoli: POS = concave curve
  • Inversion/eversion of calcaneus: POS = more everted calcaneus
  • Bulge in region of TNJ: POS = more bulge TNJ
  • Congruence of medial longitudinal arch: POS = flat arch
  • ABD/ADD of the forefoot on the rear foot: POS = more toes lateral
26
Q

Measurements for determining if the calcaneus is supinated or pronated

A
  • Normal foot: 0 to +5
  • Pronated: +6 to +9
  • Highly pronated: +10 or more
  • Supinated: -1 to -4
  • Highly supinated: -5 to -12
27
Q

What are the 3 CPG’s for the ankle-foot complex

A
  • Heel pain: Plantar Fasciitis
  • Ankle stability and movement coordination impairments: ankle ligament sprains
  • Achilles pain, stiffness, and muscle power deficits: midportion achilles tendinopathy revision
28
Q

What is the CPG for lateral ankle sprain (prevention)

A
  • History of prior ankle sprain: not participating in a balance/proprioceptive prevention
  • Not using an external support
  • Improper warm up with static stretching & dynamic movement before activity
  • Lack normal ankle DF ROM
29
Q

What is the CPG for chronic ankle instability (prevention)

A
  • Increased taller curvature
  • Not using an external support
  • Not participating in a balance/proprioceptive prevention
30
Q

Describe a physical exam for an ankle sprain

A
  • Swelling
  • Ankle ROM
  • Talar translation & inversion
  • Single leg balance
31
Q

Grade A evidence for ankle sprain interventions in the acute protective phase

A
  • Use of external support
  • Protective AROM, stretching, neuromuscular training
  • Manual therapy: Talus
  • Manual therapy: lymph drainage
  • Cryotherapy
  • DON’T use ultrasound
32
Q

Grade A evidence for ankle sprain interventions in the progressive loading phase

A
  • Manual therapy: mobs and manips, MWM
  • Proprioceptive and neuromuscular therapeutic exercise
33
Q

CPR for a Thrust & Nonthrust Manipulation and Exercise in Patients Post Inversion Ankle Sprain

A
  • Sx worse when standing
  • Sx worse in evening
  • Navicular drop >5.5 mm
  • Distal tibiofibular joint hypomobility
  • Thrust: rearfoot distraction and proximal tib-fib PA
  • Non-thrust: talocural PA, subtalar lateral glide eversion, & distal tib-fib
34
Q

CPG for heel pain/plantar fasciitis patient exam findings

A
  • Plantar medial heel pain mot noticeable with initial steps after
  • Period of inactivity but also worse following prolonged weight bearing
  • Heel pain precipitated by a recent increase in weight bearing activity
  • Reproduction of the reported heel pain with palpation/provocation of the proximal insertion of the plantar fascia
  • Positive windlass test
  • Negative tarsal tunnel tests
