Summary

Toe walking requires less ankle and knee muscle strength than normal walking. This may offer advantages for individuals with upper motor neuron injury and lower extremity weakness.

Area of Science:

  • Biomechanics
  • Human gait analysis
  • Neuromuscular function

Background:

  • Toe walking is a common gait deviation observed in individuals with upper motor neuron injuries.
  • Understanding the biomechanical demands of toe walking is crucial for developing effective rehabilitation strategies.

Purpose of the Study:

  • To compare the peak muscle strength requirements of the ankle and knee during toe walking versus normal heel-toe walking.
  • To investigate the potential compensatory advantages of toe walking in individuals with distal muscle weakness.

Main Methods:

  • Motion analysis and force platform data were collected from able-bodied adults during both toe walking and normal walking.
  • Sagittal plane joint torques and powers were compared between the two conditions using paired t tests with Bonferroni correction.

Main Results:

  • Toe walking demonstrated reduced peak ankle plantarflexor torque and power generation compared to normal walking.
  • Ankle dorsiflexor torque and knee extensor torque/power were significantly lower or absent during toe walking.
  • Hip extensor torque and power generation during loading response were greater in toe walking.

Conclusions:

  • Toe walking may necessitate less ankle plantarflexor, ankle dorsiflexor, and knee extensor strength than normal gait.
  • These findings suggest potential biomechanical advantages of toe walking for individuals with upper motor neuron injury and distal weakness.
