Interventions that promote general or local relaxation can complement starching program RHS 322 15/06/1437 4 1. 2. Mental relaxation( reduce mental stress) Physical relaxation ( reduce physical stress) Also it can be classified into: 1. General relaxation 2. Local relaxation RHS 322 15/06/1437 5 Factors Affecting Relaxation RHS 322 15/06/1437 6 1- Muscle Tone Muscle tone refers to the amount of tension or resistance to movement in a muscle even during rest or relaxation. RHS 322 15/06/1437 7 Muscle Tone. Cont., Muscle tone is maintained through the activity of the muscle spindles circuit. (Muscle spindles are modified muscle fibers called intrafusal muscle fibers). RHS 322 15/06/1437 8 2- Postural Tone It is the muscle contraction against gravity to maintain posture (it is concerned mainly about the anti-gravity muscles). Postural tone is maintained by a reflex mechanism called myotatic or stretch reflex. RHS 322 15/06/1437 9 2- Postural Tone. Cont., Any stretching of muscles by an external force, such as the force of gravity, stimulates sensory receptors (muscle spindles) situated within the muscles giving rise to a discharge of motor impulses to the same muscles. These motor impulses will cause stimulation of sufficient numbers of motor units leading to an increase tension of the muscle. RHS 322 15/06/1437 10 Postural Tone. Cont., The degree and location of postural tone varies with any alteration in posture. in upright positions, where the force of gravity tends to stretch muscles more strongly, in recumbent positions, where the effects of the force of gravity is adequately counterbalanced by full support of the body. RHS 322 15/06/1437 11 Postural Tone. Cont., recumbent positions provide full support for all segments of the body general relaxation. RHS 322 15/06/1437 12 3- Voluntary Movement After any muscle contraction and completion of the movement, the muscles come to rest and relax. There is a recognized biological principle that activity of living cells tends to be followed by inhibition of that activity (contraction=relaxation). RHS 322 15/06/1437 13 Voluntary Movement. Cont., Contraction in any one group of muscles is accompanied by a reciprocal relaxation of the antagonistic group to allow movement to take place smoothly. These facts are of importance during consideration of methods designed to obtain relaxation of a particular group of muscles (Reciprocal inhibition). RHS 322 15/06/1437 14 4- Mental Attitude Mental attitudes such as fear, anger and exciting give rise of the muscle tension and preparing the muscle for rapid or forceful action. Normally, this tension is reduced with relaxation and when the need for it no longer exist, but in some cases it may become habitual and lead to change of normal posture. RHS 322 15/06/1437 15 5- Pathological Tension in Muscle The tension of higher motor centers (upper motor neuron lesions) leads to increase tension of relaxed muscles which varies from hyper tonicity to spasticity or rigidity. A temporary reduction in this tension in the affected area can be achieved in some cases by suitable means which promote relaxation, and this allows re-education of any functional activity which remains to take place. RHS 322 15/06/1437 16 Relaxation training RHS 322 15/06/1437 17 Relaxation training Relaxation training, using methods of general relaxation (total body relaxation), has been used by a variety of practitioners to help patient to Relieve pain Relieve muscle tension, anxiety or stress Relieve associated physical and mental dysfunctions, including tension headaches, high blood pressure, and respiratory distress RHS 322 15/06/1437 18 Common elements of relaxation training 1. Relaxation involves a reduction in muscle tension in the entire body or the region that is painful or restricted by conscious effort and thought. 2. Comfortable positions and support (Prone lying, Supine lying, Half lying, Side lying) RHS 322 15/06/1437 19 3. Training occurs in a quiet environment with low lighting and soothing music or an auditory cue on which the patient may focus. 4. The patient perform deep breathing exercises or visualizes a peaceful scene. 5. When giving instructions the therapist uses a soft tone voice. 15/06/1437 20 Lying supine RHS 322 15/06/1437 21 Half Lying This is similar to the previous position but breathing is easier as there is less weight on the back and abdominal pressure on the under surface of the diaphragm is reduced. An armchair makes quite a good substitute for a plinth or bed, the things are fully supported and the feet rest on the floor, or a footstool, or a Tshaped footrest. RHS 322 15/06/1437 22 Side lying RHS 322 15/06/1437 23 Prone Lying RHS 322 15/06/1437 24 Examples of approaches to relaxation training RHS 322 15/06/1437 25 1. Autogenic training. It involves conscious relaxation through autosuggestion and a progression of exercises 2. Progressive relaxation. It uses systemic, distal to proximal progression of voluntary contraction and relaxation of muscles. 3. Awareness through the movement. It combines sensory awareness, movements of the limbs and trunk, deep breathing, conscious relaxation procedures, and selfmassage to alter muscle imbalances and abnormal postural alignment to remediate muscle tension and pain. RHS 322 15/06/1437 26 Sequence for progressive relaxation techniques 1. Place the patient in quiet area and in a comfortable position, and be sure that restrictive clothing is loosened. 2. Have the patient breath in a deep, relaxed manner. 3. Ask the patient to contract the distal musculature in the hands or feet voluntarily for several (5 to 7) seconds and then consciously relax those muscles for 20 to 30 seconds. RHS 322 15/06/1437 27 Sequence for progressive relaxation techniques. Cont., 4. Suggest that the patient try to feel a sense of heaviness in the hands or feet and a sense of warmth in the muscle just relaxed. 5. Progress to a more proximal area of the body and have the patient actively contract and actively relax the proximal musculature. 6. Suggest to the patient that he or she should feel a sense of relaxation and warmth throughout the entire limb and eventually throughout the whole body. RHS 322 15/06/1437 28 Local Relaxation 1. 2. 3. Preparatory to massage and passive movement. It can complement starching program For relief of spasm. To prevent adaptive shortening. RHS 322 15/06/1437 29 Local relaxation is gained through 1. Heat: superficial or deep heat is applied to increase circulation to the soft tissue. (increase soft tissue extensibility prior stretching exercises) 2. Massage: superficial and deep massage can be used to increase local circulation and decrease muscle spasm. 3. Biofeedback: it reduce the amount of tension in a muscle (visual and /or auditory biofeedback). RHS 322 15/06/1437 30 4. Joint traction or oscillation: slight manual distraction of joint surface can be used to decrease muscle spasm around the joint. 5. Contrast method 6. Reciprocal method 7. Suggestion method RHS 322 15/06/1437 31 Physiology Strong contraction of the muscle is followed by an equal relaxation of the same muscle or Excitation= inhibition RHS 322 15/06/1437 32 technique The technique consists of sequence of contractions of the muscles performed, usually, in a distal to proximal sequence in each limb or pair of limbs in turn followed by letting go or relaxation for an equal or longer period of time Then the contractions for each limb part are usually added to one another so that tension in the limb is total and relaxation should be controlled in reverse sequence RHS 322 15/06/1437 33 Value It can be used for a limited part of the body, for example, for relaxation of the hand or of the shoulder girdle or of the hip adductors and lateral rotators. RHS 322 15/06/1437 34 physiology The antagonistic groups of the muscles always relax reciprocally and to equally to the contraction of the agonist group of muscles. Tension will be relieved by contraction of the antagonistic muscles. RHS 322 15/06/1437 35 technique 1. The sequence used is more usually proximal to distal RHS 322 15/06/1437 36 technique 1. In this technique the therapist provides comfortable relaxing conditions for patient: 2. A warm well-ventilated room 3. A comfortable support 4. Light covering RHS 322 15/06/1437 37 5. Then by using quiet hypotonic mellow tones 6. The patient is told to think about each part of the body in turn. To think that it is very heavy and this suggestion is repeated several times until the limb gives the appearance of relaxation, e.g. until the lower limb is rolled out RHS 322 15/06/1437 38 The technique This is used for relaxation of the limbs. The arm/s or leg/s may be swung back and forward until they feel numb. . The sensory receptors have accommodated to the constant movement. This type of swinging may be aided by adding from a 1/2 to 1 kg weight to the limb RHS 322 15/06/1437 39 Value This type of swinging is of particular value to reduce the rigidity of Parkinsonism, but is also used for shorter periods of time to mobilize joints by patient activity. It is the most suitable for the shoulder, hips, knee and lumbar spine RHS 322 15/06/1437 40 9. Active inhibition techniques: are reflex relaxation procedures that therapist use to inhibit muscle prior to stretching or lengthening. Active inhibition techniques include: 1. Contract- relax 2. Contract - relax –contract 3. Agonist contraction RHS 322 15/06/1437 41 Start with the tight muscle in comfortably lengthened position Ask the patient to isometrically contract the tight muscle against resistance for 5 to10 seconds, then relax. Repeat the procedure several times. RHS 322 15/06/1437 42 Follow the same procedure as done for contract- relax, then ask the patient to perform concentric contraction of the muscle opposite to the tight muscle. RHS 322 15/06/1437 43 Passively lengthen the tight muscle to a comfortable position. The patient perform a dynamic contraction of the muscle opposite the tight muscle. Apply mild resistance to the contracting muscle, but allow joint movement to occur. The tight muscle will relax as a result of reciprocal inhibition. RHS 322 15/06/1437 44 By sight By palpation By passive movement By shacking the limb By raising the limb and sudden fall down By EMG RHS 322 15/06/1437 45 1. Decrease in muscle tension 2. Lowered heart and respiratory rates and blood pressure 3. Increase skin temperature in the extremities associated with vasodilatation 4. Constricted pupils 5. Eyes closed and flat facial expression 6. Jaw and hands relaxed with palms open 7. Decreased distractibility. RHS 322 15/06/1437 46
