Marcha Humana - Fases De La

An fascinating feature of the fases de la marcha humana (human gait cycle) is the "Inverted Pendulum" mechanism. This biomechanical phenomenon allows humans to walk with incredible energy efficiency by reusing mechanical energy from one step to the next. The Energy-Saving Cycle

| Phase | % of Cycle | Description | Key Muscle Action | |-------|------------|-------------|--------------------| | 1. Initial Contact (Heel Strike) | 0% | Heel touches ground. Ankle in neutral/dorsiflexion, knee extended, hip flexed ~30°. | Tibialis anterior (eccentric to control foot flat) | | 2. Loading Response | 0-10% | Foot becomes flat. Knee flexes slightly (shock absorption). | Quadriceps (eccentric), Gluteus maximus | | 3. Midstance | 10-30% | Body weight passes over stable foot. Single-leg support. | Gluteus medius (pelvis stabilization), Soleus | | 4. Terminal Stance | 30-50% | Heel rises; body advances over forefoot. Ankle moves from dorsiflexion to plantarflexion. | Gastrocnemius, Soleus (push-off preparation) | | 5. Preswing | 50-60% | Last double-support phase. Weight transfers to opposite limb. Toe-off occurs. | Rectus femoris, iliopsoas (initiate swing) | fases de la marcha humana

Los trastornos de la marcha se refieren a alteraciones en la marcha humana que pueden ser causadas por lesiones musculoesqueléticas, enfermedades neurológicas o trastornos del sistema nervioso. Algunos ejemplos de trastornos de la marcha incluyen: An fascinating feature of the fases de la

total. Es el periodo en el que el pie permanece en contacto con el suelo y soporta la carga corporal. Se subdivide en: Contacto Inicial (0-2%): Initial Contact (Heel Strike) | 0% | Heel touches ground
