Derived position Prepared by Sajida Mazhar Position derived from Standing By alternation of the arm 1. Wing Standing The hands rest on the crests of the iliac, the fingers, which are extended and adducted, being anterior and the thumbs posterior. The wrists are extended, forearms are pronated, elbows flexed and shoulders adducted.

The elbow point straight side ways. Muscle work: The adductors of the shoulder joint Extensors of the elbow work slightly to press the hand to the trunk. Position derived from Standing By alternation of the arm Effect and uses. As the arms are held away from the trunk from the axilla to the iliac crests, the positions allow the phys. To grasp the patient round the shoulder during some trunk exercise.

The fixed position of arm prevents their swinging during trunk exercises. this usually amplifies the movement and leaves the thorax free, the position should be avoided unless it serves some definite and useful purpose Position derived from Standing By alternation of the arm 2. Low wing Standing The hands rest on the crests of the iliac, the fingers being placed across the front of the hip joints. The wrists are extended, forearms are pronated, elbows flexed and shoulders adducted. The elbow point straight sideways. Muscle work: The adductors of the shoulder joint

Extensors of the elbow work slightly to press the hand to the trunk. Effect and uses. This is a position of control as the patient is able to feel with the hands the movement of flexion at the hip joint, tilting and lateral swing or any rotation of pelvis, which may occur during the performance of exercise. Position derived from Standing By alternation of the arm Bend Standing The shoulders are laterally rotated and adducted strongly, the elbows are flexed, and the forearms

are supinated with wrists and fingers flexed to rest above the lateral border of the acromion process. Muscle work: The lateral rotator and adductors of the shoulder work strongly. The retractors and depressors of the scapulae work strongly as fixators. The flexor of the elbows and Supinator of fore arm work to maintain the position of forearms. The flexor of the wrists and finger may work slightly. Bend Standing Effect

and uses. The position is corrective for the position of the upper back, and the thorax is expanded. It may therefore be held during some trunk exercises to intensify their effect or used prior to arm stretching exercises. Full flexion of the elbow is reduced the leverage of the abductor muscles of the shoulder joint, making it a suitable position from which to perform abduction movements when these muscles are weak 4. Reach Standing

4. Reach Standing The shoulders are flexed and the elbows extended so that the arms are held parallel, Shoulder width apart and at right angle to the body. Muscle work:

shoulder flexors maintain the position against gravity. The transverse back muscles control the forward movement of the scapulae round the chest wall, which is associated with shoulder flexion. The extensors of the elbow, Radial flexors of the wrist and Extensor of the Finger work slightly to keep the arm straight. Effect and uses. used prior to some arm and trunk exercises in sagittal plane, and to assist balance during balance walking sideways. hand may be supported on, or may grasp, some apparatus and this obviate the use of the shoulder flexors muscles when the arm are used to control or steady the body for leg or head exercises.

5. Yard Standing The arms are straight and elevated sideways to a horizontal position. Muscle work: The abductors, extensors and lateral Rotators of the shoulder work Rotators of the Scapulae to stabilize the arms. The Extensors of the Elbows, Wrists, and Fingers work to hold limb in a straight line. The tendency to elevate the shoulder girdle is controlled by the scapulae

depressors. Yard Standing Effect and uses. The abductors of the shoulder work at a marked s the length of the weight arm of the lever so greatly that of the power arm. The position is corrective for posture of the upper back,

facilitates body balance and is convenient for arm swinging exercises. 6. Stretch Standing The arms are fully elevated so that they are in line with the body, parallel to each other and with palms facing Muscle work: The Abductors, Extensors and Lateral Rotators of the shoulder work Strongly in conjunction with The lateral Rotators of the Scapulae, to hold the arms in position. The Extensors of the Elbows keep them

Straight The Wrist and Fingers are kept in alignment by interplay between the muscles working over the wrist and by the Extensors of the Finger Effect and uses. The muscles work is strong, often due to the tension of shortened opposing muscles, particularly pectoralis major and minor and latissimus dorsi.

expands the thorax and respiration is difficult,and arterial circulation to the arms is impeded by gravity. unsuitable for weak patient or those who suffer from respiratory conditions. It is strongly corrective for the position of

the upper back and gives a felling of stretching the spine. The hands may grasp some over-head support or the fingers may be clasped. When one arm holds the position a lateral flexion of the thoracic spine to the opposite side maintains the equilibrium of the body. This may be useful in the treatment of scoliosis. By alternation of the legs 1. Close Standing The legs are rotated inwards at the hips so that the medial borders of the feet are adjacent.

Muscle work: The leg Muscles work more strongly than in the fundamental position. Effect and uses. The size of the base is reduced and balance is more difficult , it is therefore a progression on the standing position. Relaxation of the lateral rotators of the hip often result in a loss of the bracing effect on the whole leg including the longitudinal arches of the feet, which accompanies the contraction of these muscles when the foot is fixed. 2. Toe standing The heels are pressed together and raised from the floor. Muscle work: The Planter flexors of the Ankle Joint work Strongly against

gravity to keep the heels elevated. All the leg Muscle work more strongly than in the fundamental position to keep the balance Effect and uses. The base is reduced and the center of gravity raised, so this is used as a balance position. Strong work of the foot muscles braces the longitudinal arches and there is a tendency for whole body to stretch, which is of value in the treatment of postural flat feet and posture training generally. 3. Stride Standing The legs are abducted so that the heels are two foot-lengths apart. The feet remain at the same angle as in the

fundamental position and the weight is equally distributed between them. Muscle work: The abductors of the hips may work to prevent the leg from sliding Effect and uses. The effective base is much enlarges laterally, making this as easy and stable position from which to perform exercises, especially those in a frontal plane. Walk Standing One leg is placed directly forwards so that the heels are two-foot length apart and are on the same line. The body weight is equally

distributed between them. Muscle work: The Extensor of hip and Knee of the leg work strongly to maintain the position Effect and uses. The base is much enlarges in the antero- posterior direction stabilizing the body for exercises in a sagital plane. Rotation of the pelvis towards the side of the forward leg is prevented

by the position of the back leg; the position therefore may be used to localize rotation to the spine. Tension of the hamstrings of the forward leg likewise prevents forward tilting of the pelvis in the trunk flexion exercises Half Standing The Whole weight of the body is supported on one leg; the other may be free or supported in a variety of positions.

Muscle work: The abductors of the hip of the standing leg work to maintain the center of gravity over the base by a slight lateral tilting of the pelvis andThe lumber side flexors of the opposite side work to bring the trunk into alignment. All the muscle of the supporting leg works more strongly than in standing to support the additional weight and preserve balance. Effect and uses. The unsporting leg is free for movement. Balance is more difficult as the size of the base is reduced. By alternation of the Trunk 1. Lax Stoop standing The hips are flexed and the trunk, head and arms are relaxed so that they hang forwards and downwards.

Balance is maintain by a slight plantar flexion at the ankle joints, causing a backward inclination of the leg Muscle work: Very little muscle work is required except in the region of the ankle joint Dorsiflexors stabilize the position of the joint Intrinsic foot muscles grip the floor Lax stoop standing Effect and uses. The amount of forward flexion is dictated by the

tension, which develops in the hamstrings and lumbar muscles. The position may be used to train local relaxation and the upper body and to assist expiration. It is used prior to extension exercises of hips and spine, particularly those that occur progressively, as in uncurling to the upright position. The position is not suitable for weak and elderly

patient. When the knees are allowed to bend in the position, tension on the hamstring and lumbar muscles is reduced, giving a feeling of relaxation right through the body 2. Stoop Standing The hip joints are flexed while the trunk; head and arms remain in alignment and are inclined forwards. Muscle work: The muscles of the feet work as in the

previous position. The Extensor of the knees may work to counteract the tension of the Hamstrings. The Longitudinal and transverse back muscles and the Extensors of the shoulder and Elbow maintain the position against the pull of gravity The posterior Neck muscles, controlled by the pre-vertebral muscles, support the head. Stoop standing Effect and uses. The strong work for the neck and back

muscles with stretching of the spine, which occur in the horizontal position, trains good posture of the upper back Fixation in flexion of the lumbar spine localizes movement to the joints above this level it is valuable but difficult position to hold correctly. Fall out standing Lunge standing By alternation of the legs and Trunk

Fallout Standing 3. One leg is placed directly forwards to a distance of three footlengths and this knee is bent; the back leg remains straight and the body is inclined forward in line with it. Muscle work: The Extensors and the Foot muscles of the forward legwork strongly to support most of weight, the Extensor of the back leg keep the trunk and leg straight. The Dorsiflexors of this footwork to keep the heel

on the ground. The head and trunk muscles work as in stoop standing, but as there is a degree of rotation and the lateral tilt of the pelvis away from forward leg, balance is maintained by the action of the trunk rotators and the lumber muscles of this sides Effect and uses. The muscle power and coordination required to hold the position is it may be used in the treatment of spinal curvature. Stretching planter flexors 4. Lunge sideways Standing

Lunge positions are similar with regarding to the position of the legs, but the body always remains in a vertical position. Position derived from Kneeling Half Kneeling One knee supports most of the body weight and the other leg is bent to a right

angle at hip, knee and angle so that the foot is supported on the ground in a forward direction Half kneeling Muscle work: The abductors of the hip joint of the supporting leg, and the lumbar side flexors of the opposite side, work to balance the trunk The extensor of the hip and the knee of the forward legwork slightly to assist the balance Effect and uses. The pelvis is well fixed in the position for trunk side bending and rotation exercise when the trunk moves

in a direction away from the supporting leg. 2. Kneel Sitting The knees and hip are flexed so that the patient sits on his heels. The position is some time used for small children, but most people find it very uncomfortable Kneel sitting

3. Prone Kneeling The Trunk is Horizontal, supported under the Shoulders by the arms, and at the pelvis by the thighs, which must be held vertical. The head is head in line with the trunk Prone kneeling inclined prone kneeling Muscle work: The muscles round the Shoulder and hip joints work to stabilize the supporting limbs at right angles to the trunk The flexors of the lumbar spine prevent hollowing of the back. The Extensor of the head and neck, controlled by the pre-vertebral neck muscles, keep the head in alignment. Effect and uses. The position is stable and comfortable and suitable for many trunk

and head exercises as the spine is relieved of the weight of the head and shoulders it tends to straighten and elongate. The pelvis is free for antero-posterior and lateral movement, but fixed for rotation. The body may be inclined forwards and downward by abducting the shoulders and bending the elbows, this expands the thorax and localizes lateral flexion to the thoracic region.

Ride sitting Position derived from Sitting 1. Stride Sitting This is exactly similar to the fundamental position, except that the legs are abducted so that the feet are up to two foot-lengths apart. This increases the stability of the position, especially if, the feet are pressed to the floor. 2. Ride Sitting The patient sits on suitable apparatus, such as a gymnastic form, which may be gripped between the knees by the adductor muscles of the hips, making it a very steady position for head arm and trunk exercises. When the position is taken on a high plinth, the thigh may be strapped

to the plinth to afford additional fixation, in which case no muscles work is required in the legs. 3. Crook Sitting When sitting on the floor, the knees are bent so that the feet are together and flat on the floor. The Knees may be together or apart. Crook sitting

Muscle work: The flexors of the hip work Strongly to prevent excessive flexion of the lumbar region and to support the thighs. The flexor of the knees and Planter flexors of the ankles may also work to afford fixation of the legs. The longitudinal and transverse back muscles work strongly to maintain the upright position of the trunk. Effect and uses. The pelvis is fixed with a decreased tilt and the lumbar region is flexed so that movement can be localized to the upper trunk, as in the treatment of kypho-lordosis. Strong work for the extensors of the thoracic spine to hold the position is of value in training their efficiency.

Long sitting 4. Long Sitting This is similar to the previous position, but the knees are extended so that the whole leg is supported. The Extensors of the knees work to counteract the increased tension of the Hamstring muscles. When the legs are apart this tension is somewhat reduced, but the position is difficult And unsuitable for most adults. 5. Cross Sitting This is also similar to crook sitting, but the ankles are crossed and hips strongly abducted and laterally rotated, so that the lateral aspect of knees is pressed to the floor. Tension on the Hamstrings is reduced but the

adductors of the hip are stretched. For this reason the position is uncomfortable for most adults, but suitable for children during head, arm and trunk exercise, as the pelvis is fixed and stable. Side sitting 6. Side Sitting For left side sitting the left leg remains as in cross sitting and this hip supports the main weight of the trunk, while the right leg is abducted and medially rotated so that the lower leg is bent and to the side. The pelvis is tilted laterally to the left, and the lumbar side flexors on the right side work to keep the trunk upright. The position is used to increase lateral mobility of the

lumbar spine or for fixation in the side bend position when treating scoliosis 7. High Sitting The fundamental sitting position is taken on a high plinth or table but the feet remain unsupported. This is convenient for some foot and knee exercises. Stoop sitting Fall out sitting Position of the Trunk 8.Stoop Sitting This is similar to but easier and more stable than stoop standing position, and is therefore very useful for arm and upper

back exercises when hollowing of the lumbar region is to be avoided The arms may be folded and supported on a table allowing the back muscles to relax. This arrangement is convenient for giving back massage when prone lying is impracticable. 9. Fallout Sitting position is same as fallout standing except that the hip and thigh of the forward leg are supported across a stool, balance is therefore easier and the patient is able to concentrate on movements, which may be added. Position derived from Lying

1. Crook lying From Lying, the hips and knees are bent so that the feet rest on the floor or plinth. Provided the feet are fixed by friction, very little muscles work is required apart from that of the abductors and medial rotators of the hips to prevent the knees from falling apart. Effect and uses.

Tension is removed from the structures anterior to the hip joint so that the pelvis rolls backwards and the lumbar spine is relaxed on to the supporting surface. As the whole trunk is relaxed and supported horizontally and fixed by its own weight it is an easy position and extensively used to train relaxation and posture. 2. Crook Lying with pelvis lifted From the previous position the pelvis is elevated so that the trunk rests on the shoulders and is brought

into line with the thighs. A firm pillow may be used to support the buttocks, or the Extensors of the hips may work to hold the position. Effect and uses. Pressure of the viscera on the pelvic floor is relieved by gravity as the weight of the viscera is directed backwards and upwards towards the diaphragm; because of this, breathing may be hampered

slightly. The position is useful during re-education of muscles of the pelvic floor 3. Half Lying The Trunk is supported in the oblique position by inclination of the long end of the plinth, or by the arrangement of pillows, while the leg is supported horizontally. It is important to see that the trunk is in an alignment to avoid slumping and so impeding respiration

Effect and uses. The body is relaxed and comfortable in this position and it is suitable for weak and elderly people because breathing is easier than in lying, the thorax being less fixed by the weight of the trunk. It is much used for ward exercise and in the treatment of many chest condition The knees may be bent to increase relaxation of the abdominal wall, or the lower leg may hang over the end of the plinth with the feet

resting on the floor. 4. Prone Lying Lying face downwards, the body is fully supported anteriorly on the plinth or floor. The position may be active or relaxed. The Active position. When this is used as a static holding for posture training or prior to exercises, the head is slightly raised from the supporting surface and the shoulder are drawn downward and backwards, The heels being held together and the toes stretched Muscle work: The pre and post-vertebral neck muscles work to maintain the position of the head. The Retractors and Depressors of the scapulae work to brace the upper back The Lateral Rotators of the Hips keep the heels together. The Relaxed position. No muscle work is required for the relaxed position. In this case the head is usually turned to one side and rested on the

hands for comfort and ease in breathing, while the heels roll apart. Placing a pillow under the abdomen and another under the lower leg, so that the hip and knee joints are slightly flexed and the feet rest free from pressure may still further reduce tension. Effect and uses. Breathing is some what restricted by the pressure of the weight of the body on the chest and abdomen, making the position unsuitable for those with heart or respiratory disease 5. Leg prone Lying This is taken on a high plinth, the legs being supported from the anterior superior spines to the feet and stabilized by a strap. The body is held in line with the leg and is unsupported over the end of the plinth. A stool is in position under the trunk to afford support by

the arms in the resting position. Muscle work: The pre-vertebral and posterior neck muscle, the extensor of the hip, and the longitudinal and transverse back muscle work strongly to maintain the position of the trunk against gravity The extensor of the shoulders and elbow hold the arms to the sides. The Flexors of the lumbar spine control the lumbar region, which tend to become hollowed. Effect and uses.

The muscles work is strong and corrective for the position of the trunk, and strong-arm, head and back exercises can be added to increase this effect. 6. Side Lying Details of this position vary considerably according to the purpose for which it is to be used. 1. The patient rolls on to the side from lying or prone lying, using the under arm to support the head. It is an unsteady position used some times for strong trunk side bending exercise

2. Alternatively the shoulders may be stabilized by support from the upper arm resting on the ground or plinth in front, the legs being free for movement. When the under hip and knee are fully flexed the pelvis is relatively well fixed, so that movements of flexion and extension can be localized to the hip joint of the uppermost leg. This is useful especially in sling exercise. Conversely, if resting the upper most knees on the plinth stabilizes the pelvis, shoulder exercise for this side of the body can be performed. 3. An ideal position for relaxation for may people is provided by adapting. Three pillows are required, one for the head, one for the

uppermost arm to support it and free the chest and so assist respiration, and a third to support the upper most leg which is bent 7. Sit Lying The patient lies supine with the knees bent and the lower leg hanging vertically over the end of the plinth. There is a tendency for the lumbar region to extend owing to tension of the hip flexors.

Position derived from Hanging 1. Fall Hanging The body is supported in the oblique position by the arm, which grasp a horizontal bar, and by the feet, which rest on the floor. The arms are vertical so that the shoulders fall directly below the hands, while the rest of the body is inclined and straight

Muscle work: The flexors of the finger grasp the bar and the wrist; Elbow and Shoulder muscles work to reduce tension on these joints. The retractors of the Scapulae work strongly to draw the trunk upward between the arms. The flexors of the Atlanto-occipital joint and of the cervical spine prevent the head from falling backwards. The Longitudinal and transverse back muscles support the trunk. The Extensor of the hips keeps the trunk in alignment and the Planter flexors press the feet to the floor. Effect and uses. The position required very strong muscles work for back muscles, especially the scapulae retractors, which work against gravity and the weight of the body.

2. Crouch Sitting The hips and knees are fully bent while the trunk is straight and inclined forwards to allow the hand to rest on the floor. The weight is supported mainly on the toes, the heels being together and the knees pressed apart. Balance is maintained by the arms, which are shoulder width apart and vertical. Muscle work: The intrinsic muscles of the feet grip the floor.

The longitudinal and transverse back muscles keep the back straight. The pre-vertebral and posterior neck muscles support the head. Effect and uses. This is useful starting position for strong leg extension exercises, as it is steady and the muscles concerned are stretched between their points of attachment. It is much used in training correct landing from high jumping 3. Prone Falling The legs are extended in line with the trunk from the crouch position so that the body is supported on the arms,

which are vertical, and on the toes. Muscle work: The Extensor of the elbow and all the muscle of the shoulder region work strongly to support the weight of the body, while the serratus anterior hold the scapulae firmly against the chest wall. The Neck Extensors, controlled by the prevertebral muscles, maintain position of the head against the pull of the gravity. The Flexors of the lumbar spine prevent sagging of the trunk. The Extensors of the knees keep them straight. When the foot is fixed in the dorsi flexion the long flexor of the toes work with excellent leverage to grip the floor.

Effect and uses. Many muscles work strongly and the necessary coordination is difficult, the position is therefore only suitable for those whose arm are strong in relation to their body length and weight
