Chapter 6 Rest and Exercise • Rest can make clients relax, refresh and relieve mental stress • Mobility facilitates pulmonary functioning and increases peripheral blood flow. Regular exercise contributes to physiological functioning of each part of body system. • Hospitalized clients need adequate rest,but they will face more physical and mental problems without adequate exercise • Nurses should assist clients with rest and exercise properly. Section 1 Rest Rest Benefits of Rest Conditions of Thorough Rest Sleep 觉 Concept of Rest • Rest – Rest is a state of decreased mental and physical activity that leaves a person feeling refreshed, rejuvenated, and ready to resume the activities of the day – Physical comfort – Freedom from worry – Comfortable environment Benefits of Rest Rest and recovery from diseases – Promote recovery ① ② ③ ④ ⑤ relieve tiredness and stress maintain the normality of physiological regulation. promote development of body decrease exhaustion of energy. promote protein synthesized and tissues rehabilitated.

Following good sleep hygiene habits sleep • Concept: – Sleep is a recurrent, altered state of consciousness that occurs for sustained periods, restoring a person’s energy and wellbeing – first as a discrete state of reduced responsiveness to external stimuli, from which a person can be aroused; – second as a continuous cyclical change in level of consciousness sleep Physiology of Sleep Normal Sleep Requirements and Patterns Factors Affecting Sleep Sleep Disorders Characteristics of sleep in hospitalized clients Implementation Physiology of Sleep 1.mechanism of sleep The reticular activating system (RAS) located in the upper brainstem the bulbar synchronizing region (BSR) in the pons and medical forebrain work together, alternately activating and suppressing the brain’s higher centers to control sleep 2.physiological characteristics of sleep • Sensory perception • Skeletal muscle reflex muscle hypotonicity • autonomic nervous function : – P、R、BP、urine、gastric juice、saliva、 BMR 3. Stages of Sleep • EEG: • EOG: • EMG: Two stages: non- rapid eye movement sleep, NREM sleep(slow wave sleep, SWS or orthodox sleep,OS) rapid eye movement sleep, REM sleep(fast wave sleep, FWS; or paradoxical sleep,PS)。 Characteristic of Sleep Cycle Stages Stage1: NREM •The slightest level of sleep •Lasts a few minutes •Physiological activity decreases, vital signs fall gradually and metabolism begins to slow down •People easily aroused by sensory stimuli such as noise •If a person awakes, feels as though daydreaming has occurred •Reduction in autonomic activities (e.g., heart rate) Stage2: NREM •Period of sound sleep •Relaxation progresses •Arousal is still easy •Lasts 10 to 20 minutes •Body functions still slowing Stage3: NREM •Initial stages of deep sleep •Sleeper difficult to arouse and rarely moves •Muscles completely relaxed •Vital signs decline but remain regular •Lasts 15 to 30 minutes Stage4: NREM •Deepest stage of sleep •Very difficult to arouse sleeper •If sleep loss has occurred, sleeper will spend most of night in this stage •Restores and rests the body •Vital signs significantly lower than during waking hours •Possible sleepwalking and enuresis •Hormonal response includes secretion of growth hormone REM Sleep mental restoration • Stage of vivid, full-color dreaming (less vivid dreaming may occur in other stages) • First occurs approximately 90 minutes after sleep has begun, thereafter occurs at end of each NREM cycle • Typified by autonomic response of rapidly moving eyes, fluctuating heart and respiratory rates, and increased or fluctuating blood pressure. Secretion of Epinephrine rises. Angina pectoris., • Loss of skeletal muscle tone except eye muscle Asthma, COPD • Responsible for mental restoration • Stage in which sleeper is most difficult to arouse • Duration increasing with each cycle and averaging 20 minutes 睡眠的分期 ,正向睡眠) 入睡期 睡眠时相各期特点 15~30min 幼儿神经 发育 20~30min sleep cycle NREM and REM alternate, duration of one cycle: 90min,4~6 cycles Awakeness NREM Stage 1 NREM Stage 2 NREM Stage 3 NREM Stage 4 REM NREM Stage 2 NREM Stage 1 NREM Stage 3 0.5~7min,30~45min begin NREM Stage 3 and 4, duration a few minutes to 1h。70 ~ 90min,1st REM occurs, 5min(20min), Duration increasing with each cycle and averaging 20 minutes 睡眠周期 睡眠周期 Characteristics of sleep stage and cycle • 60~120min, average 90min • 4~6 cycles, • If a person awakens from sleep during any stage, sleep begins again at stage 1 • With each full sleep cycle, stages 3 and 4 shorten, and the period of REM lengthens. REM sleep may last 30 to 60minutes during the last sleep cycle. • Normal Sleep Requirements and Patterns • Requirement amount of sleep varies from person to person – Healthy person: Average 7.5h • Requirement and percentage of sleep stage in a cycle are related to age. •Requirements areof also influenced by other TotalInverse hours sleep decrease ratio with total hours Neonates and Infants 16~20h, factors,NREM such as individuality, health status, stage 4 decline。 Toddlers life style, behavior habit and occupation and Times of10~14h, awake increase Preschoolers stage 11~12h 1 and 2 increase so on.

For clients with muscle convulsion caused by CNS,do ROM exercise with the instruction of physical physical therapist common types of joint movement Exercise neck, shoulder, elbow, wrist, finger,coxa, knee, and ankle ,toe joints in turn 5~10 times ROM exercises for every joint common types of joint movement Movement Definition Flexion Decreasing the angle of the joint (e.g., bending the elbow) Increasing the angle of the joint (e.g., straightening the arm at the elbow) Movement of the bone away from the midline of the body Movement of the bone toward the midline of the body The state of exaggerated extension. It often results in an angle greater than 180° A body part turning on its axis toward the midline of the body A body part turning on its axis away from the midline of the body Movement of the distal part of the bone in a circle while the proximal and remains fixed Extension Abduction Adduction Hyperextension Internal rotation External rotation Circumduction ROM exercise (broken line denoting start position of motion,arrowhead denoting direction of exercise) head-neck ROM exercise (broken line denoting start position of motion,arrowhead denoting direction of exercise) spinal column ROM exercise (broken line denoting start position of motion,arrowhead denoting direction of exercise) 水平外展 shoulder 水平内收 ROM exercise (broken line denoting start position of motion,arrowhead denoting direction of exercise) ROM exercise (broken line denoting start position of motion,arrowhead denoting direction of exercise) elbow arm ROM exercise (broken line denoting start position of motion,arrowhead denoting direction of exercise) wrist ROM exercise (broken line denoting start position of motion,arrowhead denoting direction of exercise) finger ROM exercise (broken line denoting start position of motion,arrowhead denoting direction of exercise) thumb ROM exercise (broken line denoting start position of motion,arrowhead denoting direction of exercise) coxa ROM exercise (broken line denoting start position of motion,arrowhead denoting direction of exercise) knee ROM exercise (broken line denoting start position of motion,arrowhead denoting direction of exercise) ankle Cautions! • 1. Assess physical condition comprehensively including body mobility, cardiovascular and respiratory function, and joint mobility before exercises and then plan exercise program. • 2. Keep ward quiet, ventilation, temperature and moisture proper, and assist the client alter loose and comfortable dress convenient to exercise before exercise. Protect privacy of clients. • 3.During exercise, observe the reaction to exercises and activity tolerance, and observe whether there are negative effects such as stiff joint, pain, spasm. When the abnormal reaction is found, the nurse should inform the physician. • 4. The client with acute arthritis, bone fracture, ligament rupture and joint dislocation does ROM exercise with instruction of physician. • 5. Observe changes in heart rate, heart rhythm, blood pressure when the client with heart disease does ROM exercises. • 6. The nurse should introduce the client and his relatives the importance of joint ROM exercise and encourage the client participate in exercises, which can eventually make the client to exercise from passively to actively. • 7. After exercises, record time, items, times, changes in joint mobility and reaction to exercise of the client timely and properly, which provide evidence for further plan to be made. Types of Exercise__ Muscle contraction • isometric exercise • isotonic exercise • isometric (static) exercise: – Concepts: those in which there is a change in muscle tension but there is no movement in muscle length and no muscle or joint movement – Examples: quadriceps set exercises and contraction of the gluteal. – Purpose: This form of exercises is ideal for clients who are unable to tolerate an increase in activity. Isometric exercises are easily accomplished by an immobilized client in bed isometric (static) exercise – The benefits – increased muscle mass, tone, and strength, thus decreasing the potential for muscle wasting; – increased circulation to the involved body parts; and increased osteoblastic activity. – produce a moderate increase in heart rate and cardiac output, but no appreciable in blood flow to other part of the body. • isotonic(dynamic) exercise: – Concepts: involves muscle shortening and active movement. – Benefits: increases muscle tone, mass, and strength, improves joint mobility, increases cardiopulmonary function, increases circulation, and increases osteoblastic activity. – Examples: walking, swimming, dancing, jogging, bicycling, and moving arms and legs with light resistance. • Isokinetic (resistive) exercises – Concepts: involve muscle contraction or tension against resistance, thus they can be either isotonic or isometric. – purpose: During isokinetic exercises, the person moves or tenses against resistance. Special machines or devices provide the resistance to movement. These exercises are used in physical conditions and are often done to build up certain muscle groups. – Example: the pectorals may be increased in size and strength by lifting weights. • 常用的等张练习方法为“渐进抗阻练习法” (progressive resistance exercise, PRE) • 优点 – 是动态运动比较符合大多数日常活动的肌肉运动方式, 同时有利于 改善肌肉的神经控制。 渐进抗阻练习法 • 这种方法是采用逐渐增加阻力进行练习,肌肉工作能 力改进时负荷量也随之增加。采用此法训练前,须先 测定训练肌肉连续作10次等张运动的最大负荷量,即 10RM量。先后用10RM量的1/2、3/4及全量各作10 次抗阻运动,共3组运动,各组间休息1分钟,以便调 整负荷,每日锻炼1次。其中第1、2组练习实为第3 组练习的准备运动。每周复测10RM的值,据以增加 各组负荷量。 教学目标 1.realizing contents: • benefits of rest and sleep. • characteristics of every stages of sleep cycle. • factors affecting sleep. 2.master contents: • common sleep disorder and their interventions. • effect of immobility • interventions promoting clients to exercise
