Mobility and gait Flashcards
What are 2 functions of mobility?
- allow people to engage in occupations where they need to move around
- enable community and home access
- ability to walk or use mobility aids to extend work and leisure activities
What are the 2 phases of gait cycle?
Stance and phase
How long of the gait cycle is stance?
60%
What are the phases of stance?
Heel strike, foot flat, mid stance, heel off, toe off
How long of the gait cycle is swing?
40%
What are the phases of swing?
initial, mid and terminal
What are the double support phases?
Heel strike, toe off
What is cadence?
steps per minute
What is stride time?
time of a full gait cycle
What is step time?
time for completion of a right or left step
What is velocity?
walking speed (m/sec)
True or false? Stride length is related to stature?
True
True or false? Everyone develops a similar stride?
False, each individual develops a unique way of walking.
True or false? Speed and rhythm of gait depends on mood or time of day?
True
True or false? Children and the elderly have similar gaits?
False
What maintains and counteracts balance and centre of gravity?
Movement of the pelvis, upper extremity, trunk and lower legs
How should the trunk be positioned in normal gait?
Relatively erect, leans forward as speed increases, slight rotation opposite to pelvic rotation
How does the pelvis move in normal gait?
Rotates forward with swing of same leg, rotates in opposite direction of the trunk and arms, and during weight acceptance on the lower limb, the hip drops on the swinging leg side.
What do the upper extremities do in normal gait?
arm swing opposite to lower extremity motion, helps propel movement, shoulder girdle rotates opposite to pelvis.
What causes abnormal gait?
- Disorders of complex interaction between neuromuscular and structural elements - Weight - age - endurance - fatigue - Pain
What is anterior trunk bending compensating for?
inadequate knee extensors
What is posterior trunk bending compensating for?
inadequate hip extensors
What is circumduction?
swings leg in semicircle pattern
What is hip hiking?
excessive elevation of pelvis on swing side
What is Steppage/foot drop?
drag feet or lift them high and bring them down with a slap on the floor, cannot walk on heels,
What is vaulting/toe walking?
Patient walks on toes of opposite leg to create clearance
What are 3 effects of age on mobility?
- Reduced gait speed and stride length
- Stance phase and double support durations increase
- Step width increases
- Reduced plantarflexion and hip extension ROM
- Increased pelvic tilt
- Require walking aids
What are 3 other things required for mobility?
- Sensory
- Motor planning
- Timing of muscle activity
- Cognition and visual perception
- Safety
- Energy and cardiovascular health
- Vision
What are 3 impacts of impaired mobility?
- Increased risk of falls
- Inability to access home or community
- Work and leisure activities compromised
- Social isolation
- Difficulties performing ADLs
- Reduced independence
- Pain and fatigue
