Stance and gait

2 phases of walking:

  • Stance: use of extensor muscles (gluteus maximum –> quadriceps –> soleus and gastrocnemius
  • Swing phase: flexor muscles (hip-iliopsoas, knee-hamstring, ankle-tibialis anterior)

Difference between magnetic gait & Parkisonian gait:

  • In Parkinsonian gait
    – Hesitation to initiate steps
    – Lack of arm swinging
    – Retro or anteropulsion
  • In magnetic gait
    – Small steps usually come to a stop (like feet attracted to magnetic under the floor)
    – wide based gait
