Gait Training - II
Mazyad Alotaibi
Goals of Gait Training
Increase area of support, maintain center of gravity over support area Redistribute weight-bearing area Maximize functional independence and safety at a reasonable energy cost
Requirements
ROM, muscle strength and endurance, coordination, trunk balance, sensory perception, mental status Amount of weight-bearing permitted on lower limb Gait aids
Preparation for Ambulation
Review medical record Assess and know the patient’s problems and abilities.
Establish goals and expectations Determine selection, proper fit Safety belt Explain and demonstrate Body Mechanics
Preparing the Patient
Patients need to improve:
Balance Coordination Flexibility (ROM) Strength Endurance
Major Muscle Groups
Upper Extremity Shoulder depressor – latissimus dorsi, lower trapezius, pectoralis minor Shoulder adductor – pectoralis major Shoulder flexor, extensor and abductor – deltoid Elbow extensor – triceps Wrist extensor Finger flexor
Major Muscle Groups
Lower Extremity Hip Extensors Hip Abductors Knee Extensors Ankle Dorsiflexors
Progression of Ambulation
Initiate in Parallel Bars Maximum security Stability Safety Explain to patient prior to beginning treatment Demonstrate Remain inside bars to assist decreases risk of injury (
patient, self
) For PWB status, special devices may be used
Equipment
Purpose
Increases stability by increasing BOS Decreases weight-bearing Permits mobility Decreases pain
Types
Parallel Bars Walkers Crutches Cane
Gait aids
Parallel Bars
Maximum stability No mobility Adjustable Proper Fit 20-25 0 elbow flexion greater trochanter
Walker
Wider and more stable base of support, but slow gait For patients requiring maximum assistance with balance, uncoordinated Add wheels to front legs for who lack coordination or power in upper limbs Front of walker 12 inches in front of patient Shoulder relaxed and elbow flexed 20 degree
Walker
Types Standard Adjustable, Non-adjustable Reciprocal Stair-climbing Wheeled Folding Proper Fit Grip at level of trochanter, wrist crease, or styloid process Feet of walker flat, even with heels Hips/knees straight, shoes on
Axillary Crutches
Types Standard adjustable and nonadjustable Offset Triceps Proper Fit 3 fingerbreadths from axilla Handpiece at level of greater trochanter, ulnar styloid process, wrist crease 20-25 0 elbow flexion
Uses Unilateral non/partial weight bearing e.g. fracture, amputee -> 3-point gait Bilateral partial weight bearing or in coordination/ataxia -> 2 or 4-point gait Bilateral weakness of lower extremities e.g. paraplegia -> swing-to or through gait
Axillary Crutches
Advantages Increased selection of gait patterns, speed Easily adjusted (wood or aluminum) Easily stored, transported Can use on stairs, crowded/narrow areas Disadvantages Less stable than walker Can cause injury to axillary nerve, vessels Requires good standing balance Elderly insecure Functional strength of UE, trunk required
Crutch Gaits
Point gait – stability, slow Swing gait – more energy, fast
Four-point gait
Good stability - at least 3 point contact ground Ataxia or incoordination Slowest, difficulty
Three-point gait/alternating
Non-weight-bearing gait for lower limb fracture or amputation 3-point PWB gait -> required 18-36% more energy per unit distance than normal NWB required 41-61%more energy per unit distance than normal
Two-point gait
Faster than 4-point gait but less stability Decrease both lower limbs weight-bearing
Swing-through gait
Fastest gait, requires functional abdominal muscles Required increase of 41-61% in net energy cost (= 3-point NWB)
Swing-to gait
Both crutches -> both lower limbs almost to crutch level
Forearm Crutches
Used when stability, support of axillary crutches not required, Requires more stability or support than cane.
Eliminates danger of injury to axillary nerves and vessels More functional on stairs Easy to store and transport
Forearm Crutches
Disadvantages Decreased stability Requires good standing balance and good UE, trunk strength Difficult to remove Elderly insecure Proper Fit Cuff 1 1½ inches distal to olecranon
Canes
Body weight transmission for unilateral cane opposite affected side is 20-25% Gluteus medius weakness, or pathological at knee or ankle Cane eliminate necessary gluteus medius force and reduces compressional force on hip Proper Fit Measure tip of cane to level of greater trochanter, elbow flexed 20-30 degree.
Cane
Uses Compensate for impaired balance Increased stability Advantages More functional on stairs, confined areas.
Easy storage, transport.
Disadvantages Provides limited stability decreased BOS
