Introduction[edit | edit source]
Merriam-Webster dictionary defines gait as “a manner of walking or moving on foot."[1] It involves the interaction between the nervous, musculoskeletal, and cardiorespiratory systems and is heavily impacted by human age, personality, mood, and sociocultural factors.[2] Normal gait function is determined by the optimal operation of the following: “locomotor function (for initiating and sustaining rhythmic gait), balance, postural reflexes, sensory function and sensorimotor integration, motor control, the musculoskeletal apparatus and cardiopulmonary functions."[2]
Stance Versus Swing Phase[edit | edit source]
The normal forward stride consists of two phases: the stance phase and the swing phase.[3]
- The stance phase occupies 0-60% of the gait cycle, during which one leg and foot are bearing most or all of the body weight.
- The swing phase occupies 60-100% (total 40%) of the gait cycle, during which the foot is not touching the walking surface and the bodyweight is borne by the other leg and foot.[4]
- In a complete two-step cycle, both feet are in contact with the floor at the same time for about 25% of the time. This part of the cycle is called the double-support phase.
- Gait cycle phases: the stance phase and the swing phase involves a combination of open and close chain activities.[5]
Phases of Gait[edit | edit source]
There are 8 phases of gait which are listed as follows:[4][6]
- Initial Contact
- Foot Flat
- Midstance
- Heel Off
- Toe Off
- Initial Swing
- Mid Swing
- Late Swing [7]
See below for a diagram of the gait cycle -
The video below shares a 90-second description of the basics of the gait cycle:

The following video describes the range of motion requirements involved in the different gait phases:
Range of Motion during Gait [10]
Maximum Values[edit | edit source]
Maximum range of motion values are the minimum prerequisites for a normal gait pattern.
Body part | Maximum ROM values |
---|---|
Hip | 20° of extension; 20° of flexion |
Knee | 0° (complete extension); 60° of flexion |
Ankle | 5° of dorsiflexion; 20° of plantarflexion |
Gait Kinetics[edit | edit source]
Definitions:
- Ground reaction force (GRF) - creates an external plantarflexion or dorsiflexion torque.
- Lower extremity gait musculature - creates an internal torque.
- Centre of pressure - point of application of pressure to the foot segment.
Initial contact:
Ankle -
- At initial contact - lateral calcaneus strikes the ground first.
- Point of application of GRF is slightly posterior to the axis of rotation of the foot and ankle joint - creates a plantarflexion moment at the ankle.
- Utilise dorsiflexors to oppose plantarflexor torque - internal torque controlled by tibialis anterior, extensor digitorum longus and extensor hallucis.
Knee -
- At initial contact - GRF is anterior to the knee joint creating anterior rotation of the femur.
- GRF wants to move into extension.
- Utilise flexor musculature - hamstrings - in order to control progression.
Hip -
- GRF is anterior to hip joint - creating an external torque (anterior rotation) at the pelvis.
- Utilise extensor musculature - gluteal musculature - to oppose/control the progression or external torque.
Foot flat:
Ankle -
- Centre of pressure remains at the posterior calcaneus - GRF remains posterior to the ankle.
- Utilise dorsiflexors to prevent plantarflexion from occurring at the ankle.
Hip -
- Centre of pressure and GRF remains the same - anterior to the axis of rotation.
- Anterior pelvic tilt creates a flexion torque.
- Utilise extensor musculature to control this torque.
Knee -
- Range of motion moves from 0-15°.
- GRF posterior to the axis of rotation of the knee joint - creates a flexion torque.
- Utilise extensor musculature to control knee from moving into flexion.
Mid-stance:
Ankle -
- GRF creates a clockwise torque of the proximal segment (on top of distal segment) - causing a dorsiflexion moment at the talocrural joint.
- Utilise plantarflexors to oppose the external torque.
Knee -
- GRF creates an anterior (clockwise) torque of proximal segment (on top of distal segment) - wants to move into extension by femur moving anteriorly on tibia.
- Utilise flexors to oppose this torque - activates hamstrings.
Hip -
- GRF is posterior to the axis of rotation - wants pelvis to move into a posterior pelvic tilt (extension).
- Utilise flexors to oppose extension torque.
Heel off:
Ankle -
- GRF is anterior to the axis of rotation of ankle joint - wants tibia to flex on talus.
- Creates external dorsiflexion moment at talocrural joint.
- Utilise plantarflexors to oppose this moment.
Knee -
- GRF is anterior to knee joint - pulls femur into extension, creating an external extensor torque.
- Counteracted by internal flexor torque.
Hip -
- GRF is posterior to hip joint - creates an external extensor moment.
- Counteracted by internal flexor moment.
Toe off:
Ankle -
- Centre of pressure/GRF stay anterior to axis of rotation of ankle joint.
- Creates an external dorsiflexion moment.
- Counteracted by internal plantarflexion moment.
Knee -
- GRF is posterior to axis of rotation of knee joint as knee is moving into flexion.
- Creates an external flexion moment.
- Counteracted by an internal extensor (quadricep musculature) moment.
Hip -
- GRF is posterior to axis of rotation of hip joint as hip is moving into extension.
- Creates a posterior pelvic tilt.
- Utilise flexor musculature (iliopsoas) to counteract this moment.
Internal Torque Peaks[edit | edit source]
Hip:
- Foot flat - extensor torque
- Heel off - flexor torque
Knee:
- Initial contact - flexor torque (hamstring musculature active)
- Foot flat - extensor torque (quadriceps musculature active)
- Heel off - flexor torque (hamstring musculature active)
Ankle:
- Initial contact/Foot flat - dorsiflexion torque
- Heel off - plantarflexion torque (gastrocnemius/soleus active)
