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]”
Phases of Gait[edit | edit source]
There are 8 phases of gait which are listed as follows[3][4]:
- Initial Contact
- Loading Response
- Midstance
- Terminal Stance
- Pre swing
- Initial Swing
- Mid Swing
- Late Swing [5]
The video below shares a 90-second description of the basics of the gait cycle:
Range of Motion Involved in Gait Phases[edit | edit source]
Initial contact (Heel Strike):
Involves:
- 30° flexion of the hip: full extension in the knee: ankle moves from dorsiflexion to a neutral (supinated 5°) position then into plantar flexion[7][3].
- After this, knee flexion (5°) begins and increases, just as the plantar flexion of the heel increased[3].
- Plantar flexion is allowed by eccentric contraction of the tibialis anterior
- Extension of the knee is caused by a contraction of the quadriceps
- Flexion is caused by a contraction of the hamstrings,
- Flexion of the hip is caused by the contraction of the rectus femoris[3].
Loading Response (Foot Flat):
Involves:
- Body absorbs the impact of the foot by rolling in pronation[7].
- Hip moves slowly into extension, caused by a contraction of the adductor magnus and gluteus maximus muscles.
- Knee flexes to 15° to 20° of flexion[3].
Midstance:
Involves:
- Hip moves from 10° of flexion to extension by contraction of the gluteus medius muscle[3].
- Knee reaches maximal flexion and then begins to extend.
- Ankle becomes supinated and dorsiflexed (5°), which is caused by some contraction of the triceps surae muscles[7].
- During this phase, the body is supported by one single leg.
- At this moment the body begins to move from force absorption at impact to force propulsion forward[7].
Heel Off:
Involves:
- Begins when the heel leaves the floor.
- Bodyweight is divided over the metatarsal heads[7].
- 10-13° of hip hyperextension, which then goes into flexion.
- Knee becomes flexed (0-5°)[3].
- Ankle supinates and plantar flexes[3].
Toe Off/Pre-swing:
Involves:
- Hip becomes less extended.
- Knee is flexed 35-40°
- Plantar flexion of the ankle increases to 20°[7][3].
- The toes leave the ground[3].
Early Swing:
Involves:
- Hip extends to 10° and then flexes (due to contraction of the iliopsoas muscle)[3] 20° with lateral rotation[7][3].
- Knee flexes to 40-60°.
- Ankle goes from 20° of plantar flexion to dorsiflexion, to end in a neutral position[7].
Mid Swing:
Involves:
- Hip flexes to 30° (by contraction of the adductors) and the ankle becomes dorsiflexed due to a contraction of the tibialis anterior muscle[3].
- Knee flexes 60° but then extends approximately 30° due to the contraction of the sartorius muscle[7][3] - caused by the quadriceps muscles[7][3].
Late Swing:
Involves:
- Hip flexion of 25-30°
- Locked extension of the knee
- Neutral position of the ankle[7].
The following video describes the range of motion requirements involved in the different gait phases:
