Gait Training Flashcards
Rquirements for gait
Trunk control
LE strength
Five main functions of Gait
- Support head, arms, and trunk
- Maintain upright posture and balance
- Controls the foot to allow it to clear obstacles; allows gentle heel or toe landing
- Generates mechanical energy by concentric muscle contraction to initiate and maintain forward velocity
- Provides shock absorption and stability and decreases forward velocity
Gait and age
Irregular and variable until about age 7
Toddlers learn to walk and the elderly typically resemble one another
Functional tasks in gait
Forward progression
Balance
Support of the upright body
Gait cycle
Time interval or sequence of motion occurring between two consecutive initial contacts of the same foot
-Measured as stride length
Traditional gait cycle
1 cycle: Heel strike–>foot flat–> heel off–> toe off–>acceleration–>midswing–>deceleration
2 Phases: Stance 60% and Swing 40%
Normal Stride Length
70-82cm
Normal Step Length
35-41cm
Normal Base Width
5-10cm
Normal Foot angle
5-18 degrees
Fick angle
Normal Cadence
90-120 steps per minute
Normal Gait Speed
Approximate 1.4m/sec
Center of Gravity
Typically 5cm or 2 in anterior to the second sacral vertebrae
Wider stance lowers COG
Observation of gait
Anterior view- Frontal plane motion
Lateral view- Sagittal plane motion
Posterior view- Frontal plane motion
Footwear wear patterns
Objective Functional Tests
Timed up and go test
Performance oriented balance and mobility assessment
Standardized walking obstacle course
3 Main reasons for Gait deviations
- Pathology or injury to specific joint
- Compensations for injury or pathology in other joints on the same side
- Compensation for injury or pathology on the opposite limb
Specific factors leading to gait deviations
Pain/Discomfort during WB Muscle weakness/tone abnormalities Limitation of joint ROM Incoordination of movement Changes in bone or soft tissue
Ankylosis
Fusing/Stiffening of joint
Joint instability
More than hypermobility
Reduces shock absorption ability
Antalgic
Painful
Arthrogenic
Clumsy, hobbling due to stiffness
Joint origin
Hemiplegia
Decreased use of one side, paralysis
EX: vaulting on one side to clear weak side
Cerebral Palsy
Congenital Condition
Lower or upper or both extremities affected
Doesnt change over time
