Q

Why do we analyze gait?

A
  • Identify deviations to address with intervention
  • Determine functional ambulation capability across variety of environments
  • Assess balance, safety, endurance energy expenditure
  • Need for AD/orthotics
  • Describe how interventions impacted gait
46
Q

Abnormality in gait may be caused by what?

A
  • Pain
  • Joint and/or muscle ROM limitation
  • Muscular weakness/paralysis
  • Impaired motor control
  • Neurological involvement (UMN or LMN)
  • Impaired balance
  • Leg length discrepancy
47
Q

T/F Deviations are often compensations attempting to make gait more efficient

A

True

48
Q

When analyzing gait, how can you be systematic?

A
  • Analyze from bottom up (toes to head) or top to bottom (head to toes)
  • Work in segments
  • Identify a reference limb
  • Select a plane to start in (for example, sagittal plane first, then frontal plane), but look from all planes
  • Work in phases; this will require the patient to walk back and forth several times
49
Q

What is antalgic gait? How does it affect stance phase on affected side? Step length of uninvolved side? Lateral shift?

A
  • Compensatory gait adopted to remove or decrease the discomfort caused by pain in the lower leg, pelvis, or lumbar spine
  • Decrease in stance phase in affected side will result in decrease in swing phase of uninvolved limb and thus shortened step length on uninvolved side
  • Lack of weight shift laterally over the stance limb to keep weight off the involved limb
50
Q

What are the causes of the hip deviation forward trunk lean?

A
  • Result of weak quadriceps (decreases flexor movement of knee)
  • Hip flexor contractures
  • Weak lumbar or hip extensors
  • Hypomobile joint capsule
51
Q

What are the causes of the hip deviation decreased hip extension?

A
  • Tight hip flexors
  • Decreased joint mobility (posterior roll/anterior glide tightness)
  • Weak glutes
52
Q

What is glute max role during initial contact of gait?

A

Contracts at initial contact, slowing forward motion of trunk by resisting flexion of the hip and initiating extension

53
Q

If glute max is weak how will my body compensate?

A
  • Gluteus Maximus Gait/backward trunk lean (“rocking horse gait”)
  • Trunk will quickly shift posteriorly during initial contact to try and offset forward momentum, this requires less muscle strength to maintain the hip in extension during stance phase
54
Q

What might you see with weak gluteus medius?

A

Hip drop contralateral side

55
Q

How would we compensate with weak glute medius?

57
Q

What are the possible causes of knee hyperextension during gait?

A
  • Quadriceps weakness
  • Hamstring weakness
  • Increased tone of quadriceps
  • Compensation for plantarflexion contracture or spasticity (tight gastroc)
    1. When stretch gastric – knee straight and foot dorsi flexed (essentially Midstance)
    2. Tibia progresses forward -> spastic wants to get out so tibia hyperextends to decrease dorsiflexion and decrease stretch on gastroc
58
Q

What are possible causes of decreased knee extension?

A
  • Quadriceps weakness (unable to straighten knee)
  • Knee joint hypomobility
  • Hamstring contracture or stiffness
  • Strategy to avoid heel rocker (to stop advancement of knee)

102
Q

What is festinating gait (describe CoG and BoS)? Seen in patients with what disorder?

A
  • Displacement of CoG anteriorly
  • In order to keep CoG within BoS, patient will shuffle their steps and will walk faster in an attempt to avoid losing their balance
  • Because of rigidity all joints will want to flex forward
  • Most often seen in Parkinson’s Disease, but can be seen in other basal ganglia diseases
