Walking
•Walking is the manner or way in which you move from place to place with your feet.• It is a Movement at a regular and fairly slow
pace by lifting and setting down each foot in turn, never having both feet off the ground at once.
• it is the highest level of motor control skill.
![Page 3: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/3.jpg)
• The major requirements for successful walking include:• Support of body mass, by the lower extremities • Production of locomotors rhythm• Dynamic balance control of the moving body• Propulsion of the body in the intended direction
![Page 4: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/4.jpg)
Basic terms
• Ambulation: To walk from place to place or move about.• It is a technique of post operative care in which a patient gets
out of bed and engages in light activity (as sitting, standing, or walking) as soon as possible after an operation.• Some time this term is also use in the place of walking ..
•Gait: Gait is a term to describe human locomotion, it is pattern of walking or a sequence of foot movements.
![Page 5: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/5.jpg)
Gait cycle or walking cycle
• A cycle of walking is the period from the heel-strike of one foot to the next heel-strike of the same foot• When a subject is walking on level ground, than the
movements of the lower limbs may be divided into “swing” and “stance” phases.• The swing phase occurs when the limb is off the ground, and
the stance phase when it is in contact with the ground and is bearing weight.

Purpose of walking aids
• Increase area of support or base of support• Maintain center of gravity over supported area• Redistribute weight-bearing area by decreasing force
on injured or inflamed part or limb• Can be compensate for weak muscles• Decrease pain• Improve balance
![Page 9: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/9.jpg)

Introduction of crutches
These are devices which are used to reduce weight bearing on one or both legs and also give support where balance is impaired and strength is inadequate
![Page 11: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/11.jpg)
Prerequisites for crutches
• Good strength of upper limb muscles is required.• Range of motion of upper limb should be good.• Muscle group which should be strong is given below.• Shoulder flexor, extensors and depressor• Shoulder adductors • Elbow and wrist extensors• Finger flexors
![Page 12: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/12.jpg)
Types of crutches
1. Axillary crutches/ under arm crutches
2. Elbow crutches or Lofstrands crutches
3. Forearm support crutches (gutter crutches)
![Page 13: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/13.jpg)
1. Axillary crutches /under arm crutches
• They are made of wood or metal with an Axillary pad, a hand piece and a rubber
ferrule.
• Two upright shafts connected by axillary piece on top
• Hand piece in the middle
• Extension piece below
• Extension piece and shafts has numerous holes at regular intervals so the total
length of crutch and height of handle is easily adjustable.
• A large suction tip (rubber ferrule) is attached to extension piece to allow total
contact with floor
![Page 14: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/14.jpg)
![Page 15: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/15.jpg)
• The Axillary pad should rest beneath the apex of axilla and
hand grip in slight flexion when weight is not being taken.
• When weight is being taken through axillary pad, the elbow
will go into extension and weight is transmitted down the arm
to hand piece.
![Page 16: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/16.jpg)
![Page 17: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/17.jpg)
Measurement of length
There are variety of ways it may be in lying and also in standing position.In Lying it may be with shoes off and with shoes on
1. With shoes off: measure from apex of axilla to the lower margin of medial melleolus.
2. With shoes on: 5cm/2 inches vertically down from apex of axilla to a point 20 cm lateral to the heel of shoe. Book Resource: M. Dena Gardiner
In standing with shoe off and shoe on method is same. 2 inches below the axilla to the 2 inches anterior and 6 inch lateral to
the foot in standing position.

Measurement of axillary crutch
![Page 19: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/19.jpg)
• Crutches that are too tall or too short can affect balance and also cause back pain.
• Incorrectly fitted crutches or poor posture can cause a disorder called crutch palsy in which the nerves under the arm mostly radial nerve (brachial plexuses) are temporarily or permanently damaged, causing weakened hand, wrist and forearm muscles.
![Page 20: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/20.jpg)
Advantages and Disadvantages of Under Arm Crutches
•Advantages:
• Convenience for temporary injuries• A large degree of support for the lower body• Available at low cost.• Axillary crutches allow the patient to perform a greater variety
of gait patterns and ambulate at a faster pace.
![Page 21: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/21.jpg)
Disadvantages:
• Limited upper body freedom• Axillary crutches require good standing balance by the patient.• Improper use of crutch can cause injury to axillary region, and
Strain on the arms and upper body which can lead crutch paralysis. It is a condition in which the nerves under the arms (Radial nerve and brachial plexus) are pinched and also risk of losing balance.
• Geriatric patient may fell insecure or may not have the necessary upper- body strength to use axillary crutches
![Page 22: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/22.jpg)
Precautions • Have someone nearby for assistance until accustomed to the
crutches.• Frequently check that all pads are securely in place• Check screws at least once per week.• Clean out crutch tips to ensure they are free of dirt and
stones.• Remove small, loose rugs from walking paths.• Beware of ice, snow, wet or waxed floors• Avoid crowds, leave class early.• Never carry anything in hands ,use a backpack.
![Page 23: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/23.jpg)
Elbow crutches /forearm crutches/ Lofstrand crutch
• They are made of metal an aluminum tubular shaft with
a handgrip and have a metal or plastic forearm band.
• Forearm piece bent backward and extended to 2 inches
below the elbow.
• Both handgrip and forearm piece are adjustable in
length by means of a press clip or metal button and
have a rubber ferrule.
• These crutches are suitable for patients with good
balance and coordination with strong arms. Weight is
transmitted exactly the same way as for axillary
crutches.
![Page 24: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/24.jpg)
![Page 25: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/25.jpg)
![Page 26: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/26.jpg)
Advantage of elbow crutches
Light weight Easily adjustable freedom for hand activitiesUsing forearm crutches requires no more energy, increased
oxygen consumption or heart rate than axillary crutches. Being easily stored and transferred. There is no risk of injury to the neurovascular structures in
the axillary region when using this type of crutches.
![Page 27: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/27.jpg)
Disadvantages of forearm crutches
• Forearm crutches are less stable .• They require good standing balance and upper-body strength.• Geriatric patient sometimes feel insecure with these crutches.
They may not have the necessary upper-body strength to use forearm crutches.
![Page 28: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/28.jpg)
Forearm support crutches/gutter crutches/
platform crutch
• They are made of metal with a padded forearm support Platform, Velcro strap an adjustable hand piece and a rubber ferrule.• These are used for patients with Painful wrist and
hand condition or elbow contractures, or weak hand grip
• Elbow flexed 90 degrees, The hand rests on a grip which can be angled appropriately, depending on the user's disability.
![Page 29: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/29.jpg)
• Mostly In rheumatoid disease, cerebral palsy, or other conditions for providing support. In these conditions patient cannot take weight through hands, wrists and elbows because of deformity or pain.
![Page 30: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/30.jpg)

MEASUREMENT :
IN LYING POSITION
With shoes on: measure from the point of fixed elbow till 20 cm lateral to the heel.
![Page 32: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/32.jpg)
• ADVANTAGES :• As similar like elbow crutch• These are easily adjustable.• More cosmetic than other crutches.• DISADVANTAGES :• Provide less lateral support due to absence of axillary pad.• Cuffs may be difficult to remove.• These can be expensive.
![Page 33: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/33.jpg)

Preparation For Crutch Walking
• Arms: shoulder extensors, adductors and elbow extensors even all muscles of arms must be assessed and strengthened before the patient starts walking. The hand grip must also be tested to see that the patient has sufficient power to grasp hand piece.• Legs: Strength and mobility of both legs should be assessed
and strengthened if necessary. Main attention to the hip abductors and extensor, the knee extensors and the plantar flexors of the ankle should be given.• Balance: sitting and standing balance must be tested.• Demonstration: the physiotherapist should demonstrate
appropriate crutch walking to the patient.
![Page 35: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/35.jpg)
Crutch walking
• During first time, when the patient is to stand and walk, the physiotherapist should have an assistant for supporting the patient.• Non-weight bearing: patient should always stand with a
triangular base i.e. crutches either in front or behind the weight bearing leg• Partial weight bearing: The crutches and the affected leg are
taken forward and put down together. Weight is then taken through the crutches and the affected leg, while the unaffected leg is brought through.
![Page 36: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/36.jpg)
![Page 37: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/37.jpg)
Gait pattern with crutches
• Four point gait• Three point gait • Two point gait• Two point swing through gait• Two point swing to gait (the feet are advanced by a
much shorter distance and placed behind the level of crutches)
![Page 38: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/38.jpg)
Four-point gait
In this gait pattern one crutch is advanced and then the opposite lower extremity is advanced. For example, the left crutch is moved forward, then the right lower extremity, followed by the right crutch and then the left lower extremity.• Slow, Good stability - at least 3 point
contact ground• Weight is on both lower extremities and
used with bilateral involvement due to poor balance, in coordination( Ataxia) and muscle weakness
![Page 39: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/39.jpg)
Three-point gait
• In this type of gait three points of support contact the floor.
• Non-weight-bearing gait for lower limb fracture or amputation
![Page 40: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/40.jpg)
Non Weight Bearing
![Page 41: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/41.jpg)
Two-point gait
• This gait pattern is similar to the four-point gait. However, it is less stable because only two points of floor contact are maintained. Thus, use of this gait requires better balance.
• The two-point pattern more closely stimulates normal gait, in as much as the opposite lower and upper extremity move together.
![Page 42: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/42.jpg)
• Two additional, less commonly used crutch gaits are the swing-to and swing-through patterns. These gaits are often used when there is bilateral lower extremity involvement, such as in spinal cord injuries.
![Page 43: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/43.jpg)
Swing-through gait
• Fastest gait, requires functional abdominal muscles• In the swing-through gait, the
crutches are moved forward together, but the lower extremities are swing beyond the crutches.
![Page 44: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/44.jpg)
Swing-to gait
• Both crutches -> both lower limbs almost to crutch level• The swing-to gait involves
forward movement of both crutches simultaneously, and the lower extremities “swing to” the crutches.
![Page 45: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/45.jpg)
4 point gait –Balance and confidence / full weight bearing
3 point gait – Balance and partial weight bearing
2 point gait – non weight-bearing/ full weight bearing
Point gait – stability, slowSwing gait – more energy, fast
![Page 46: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/46.jpg)
Stair ClimbingUp With GOOD, Down With BAD
![Page 47: Walking aids](https://reader035.fdocuments.in/reader035/viewer/2022081502/55612ef7d8b42aa2118b46e2/html5/thumbnails/47.jpg)
StairsTo begin, place both crutches under the arm of the injured side, holding the inside handle with the thumb. Hold onto the railing with the other hand. When using stairs, remember, “up with the good, down with the bad.”• To Ascend
• Leave crutches on the same level where standing.
• Support weight evenly on the crutch hand and railing.
• Raise the uninjured foot to the higher step, letting the injured foot trail behind.
• Straighten the uninjured leg and advance the crutches.
• To Descend
• Place the crutches on the lower step, while extending the injured foot forward. Place the crutches on both sides of the body if no railing is present.
• Support weight evenly on the crutch hand and railing.
• Move the uninjured foot to the lower step.
• Narrow steps without a railing might require sitting on each step.
