1Wellness, Health Promotion, and Exercise Training in Geriatrics Min H. Huang, PT, PhD, NCS
2Learning objectivesAnalyze the factors contributing to physical, psychological, and social wellness in older adultsDiscuss the role of physical therapists in the promotion of wellness for geriatric practice
4What is Wellness?WHO: health is “a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity.”Wellness is described in the domains of physical, psychological, and social wellbeing.Optimal aging implies maximizing one's ability to function across physical, psychological, and social domains to one's satisfaction and despite one's medical conditionsWellness is often described in terms of these three interconnected domains of physical, psychological (mental), and social well-being.Wellness is viewed by some as a process and by others as an outcome achieved through health promotion and disease prevention processes.

7Physical Activity Guidelines For older adults 65 years of age or older who are generally fit and have no limiting health conditionsOnly 34% of older adults (ages 65 to 74 years) and 17% of older adults (aged 75+ years) exercise regularly.
8Physical Activity Guidelines 10 minutes at a time is fineWe know 150 minutes each week sounds like a lot of time, but it's not. That's 2 hours and 30 minutes, about the same amount of time you might spend watching a movie. The good news is that you can spread your activity out during the week, so you don't have to do it all at once. You can even break it up into smaller chunks of time during the day. It's about what works best for you, as long as you're doing physical activity at a moderate or vigorous effort for at least 10 minutes at a time.
9Psychological wellness Emotional wellnessControl of stress and effective coping with life situationsHigh stress levels with poor coping negative physiological (e.g., CVP, MS), emotional (e.g., depression, anxiety), behavioral (e.g., inability to work, inefficiency) responses
10Psychological wellness Cognitive wellnessSkills and self-efficacy (a person's confidence in his or her ability to achieve a goal)Interest in engaging intellectually in the worldSpiritual healthValues, morals, and ethics that guide an individual's search for a state of harmony and inner balance
11Mental Health Issues that can affect Wellness DepressionRisk factors: family hx, personal hx, hx emotional trauma, chronic illness or pain, widowers, divorceesPerceived controlgreater satisfaction in life if the patient has thisSelf-efficacyperceive self as functional greater happinessProblem solving coping strategiesinformation seeking or behavioral/cognitive actions are most effectiveSelf efficacy: belief that one can organize and execute courses of action needed to achieve a desired goal or undertakingJ. Blackwood
12Social wellness Social wellness is the ability to develop and maintain healthy relationships with othersto feel connected to a community or groupto interact well with other peopleto have a support structure to call on during difficult timesSocial supports significantly influence the ability to cope with life's stressorsPeople considered socially well are usually involved with others, rather than isolated, and they report satisfactory levels of perceived social support.
13Five major factors in the construct of social wellness Social integration (“I feel close to other people in my community”)Social contribution (“My daily activities are worthwhile to my community”)Social coherence (“I can make sense of what's going on in the world”)Social actualization (“Society is improving for people like me”)Social acceptance (“People care about the social issues that are important to me”)
14Health Behavior Change For interventions to be effective, behavior must be alteredTranstheoretical Model: a continuum of motivational readiness leading to change of a problem behaviorPrecontemplationContemplationPreparationActionMaintenanceJ. Blackwood
15Transtheoretical Model Processes of Change involve a set of independent variables promoting the transitions between the stages of change
16PrecontemplationNo intention to change behavior in the foreseeable future.Many individuals in this stage are unaware or under-aware of their problems.
17Contemplation People are aware that a problem exists People are seriously thinking about overcoming it but have not yet made a commitment to take action
18Preparation Combines intention and behavioral criteria. Individuals are intending to take action in the next monthIndividuals have unsuccessfully taken action in the past year
19ActionIndividuals modify their behavior, experiences, or environment in order to overcome their problems.Action involves the most overt behavioral changes and requires considerable commitment of time and energy.
20MaintenancePeople work to prevent relapse and consolidate the gains attained during actionFor addictive behaviors this stage extends from 6 months to an indeterminate period past the initial action
215 steps for a Wellness/ Health Promotion Plan Identify the problem, explain why it is a problem, describe its implications, identify all behaviors that might influenceDetermine readiness to participate: past hx of compliance, support systemsDevelop intervention plan with specific goals and realistic time framesBegin the intervention, give support prnEvaluate the person’s success and eliminate risk behaviorsJ. Blackwood
22Strategies for Health Behavior Change Health literacyChronic disease self-managementLifestyle redesignJ. Blackwood
23Chronic Disease Self-Management Purposeto enable persons to prevent complications and control/manage their health conditionsIndividuals and familiesParticipate actively in the health care processSelf-monitoring of symptoms or physiological processesMake informed decisionsManage the impact of their health on daily lifeJ. Blackwood
24Designing a Wellness Program Population basedAddress the problems of the population, e.g. sedentary lifestyle, overweightPrograms are implemented outside of traditional health care settingsMechanisms for funding are differentPersonal, government, industry supportEmphasis is on prevention not remediationJ. Blackwood
25Barriers to a wellness program Starting the activity/changing the behaviorSocial interventionReward systemGoal setting and monitoringDecrease financial barriers by promoting an activity that can be done anywhere without lots of equipmentJ. Blackwood
26Ethical Issues with Wellness Programs Many elderly are reluctant to spend their savings on themselvesBelief systems, locus of control and religious preferences support a person’s self esteemSome risky behaviors are coping behaviorsCultural norms may interfere with behavioral outcomesAre values about health practices changing?cheaper to pay for health promotion than treating the illness.J. Blackwood
27Screening tool for physical activities and wellness programs - EASY Six-question online screening toolIdentifies potential health problems that require health care provider clearance before exercisingProvides education about each problem and the value of exerciseHelps older adults choose appropriate exercises that may not first require a physician's approval
29Screening for osteoporosis: PT can ask for Central DEXA (hip or pelvis) or Peripheral DEXA (heel, finger) (T-score below indicates osteoporosis)Family history of osteoporosis (mother, sisters, grandmother)Low body mass indexHistory of vertebral or wrist fracturesObserve presence of kyphosisLoss of height of >4 cm
30Measurements of Physical Activity (Box 24-7) Physical Activity Scale for the Elderly (PASE)Self-reported occupational, household, and leisure activities during a 1-wk period providing prompts with examples of specific activitiesAdminister by phone, mail, or personal interviewFocus on activities commonly performed by older adults by giving more weight to these activities instead of sports
31Measurements of Physical Activity (Box 24-7) PedometerSimple, inexpensiveGenerally, 10,000 steps per day is considered to afford a health benefitAccelerometerComputerized measures of step count and movementApplicable for research
32How do you assess strength in the geriatric client? MMT‘Make test’‘Break test’Difficult to differentiate between 4/5 to 5/5 - Ceiling effectMeasurement error with MMT as high as 50%5/5 strength does not accurately reflect strength for functional activitiesOther ways?e.g. Holding a standing heel rise on one leg = 3/5Resistance applied throughout the range is termed a 'make test'.Break test, Manual resistance applied at an end of range (isometric contraction).Lunsford, BR, Perry, J: The standing heel-rise test for ankle plantar flexion: criterion for normal. Phys Ther. 75, 1995, 694–698
33Supine hip extension MMT Easier to perform in the clinic because so many older adults have difficulty lying proneDistinct difference between the forces elicited at each muscle gradegrade 5, N; grade 4, N; grade 3, 66.7 N; and grade 2, 19.1 NNOT validated against the gold standard of hand-held dynamometry in the prone position.Perry J, Weiss WB, Burnfield JM, Gronley JK.

Pelvis and back elevate as a locked unit while the leg is raised by theexaminer. The hip maintains the fully extended, neutral positionthroughout the test. C. Ending position for grade 4 (good). Hip flexion occurs before pelvis elevates while the examiner raises the leg. D. Ending position for grades 3 (fair) and 2 (poor). Full elevation of the limb to the end of the straight-leg raising range with no elevation of the pelvis.Examiner feels “good” resistance for grade 3, little resistancefor grade 2, and no active resistance for grade 0.Fig 2.

35Measure RM for functional movements Example:If the chair is 21 in. high and the person can stand 10 times without using his or her arms that is the 10 RMIf the person does more or less than 10 repetitions, the surface can be raised or loweredApply this principle to other movementse.g. Bridges, lunges, wall squats, and step ups and step downs
37StrengthLeg Strength has been found to be the SINGLE most important predictor of institutionalization and more important than physiological markers or disease.An individual needs a certain level of strength (about 45% of his or her body weight) to rise from a chairOlder adults gain strength the same way that younger people gain strengthPage 66 guccione.
38Conditions associated with muscle weakness Iron deficiency anemiaDecreased Hgb and HctHypercalcemiaElevated Ca++ depress nervous system responses and muscle actions become sluggish and weakHypokalemiaWeakness progresses over weeksHypophosphatemiaDisrupt energy metabolismHyponatremiaHypernatremiaHypercalcemia: increased Ca due to hyperparathyroidism and paget’s disease; elevated calcium levels depress nervous system responses and muscle actions become sluggish and weakHypokalemia: decresed serum potassium due to chronic use of diuretics, muscle weakness progresses over weeksHypophophatemia: low serum phosphate levels: stored in the bone as hydroxyapatite and contributes to energy metabolism and cell membrane function and regulationHyponatremia:; decreased serum sodium, diuretics, diarrhea, vomitingHypernatremia:J. Blackwood
39Principles of Specificity & Overload Specific challenges with aerobic capacity result in endurance-training adaptationsSpecific strength training results in strength adaptations.Overload: challenge the muscle/system more than what is normal stimulus.J. Blackwood
40The ability of tissue to absorb and dissipate forces is dependent on many variables, including the time over which the stressor is applied; the direction, magnitude, and combination of stressors applied; the physiological condition of the tissue, organ, or system; the frequency of the application of a stressor and length of time between the applications; and even the psychological state of the person and the “environment” in which the stressor is applied. In the clinic, physical therapists can modify these variables within an exercise program to achieve a desired outcome. For example, the PST can be used to positively impact the cardiopulmonary, musculoskeletal, and vestibular systems in a frail older woman who has been sedentary for several years and now has increased fall risk and an inability to tolerate walking 1000 feet (community distance) at a reasonable pace. The physical therapist may choose initially to promote safety and reduce the risk of falling by having her use a walker for support and to decrease her unsteadiness, thus reducing the demand of the task to a level that matches the patient's current capabilities. Resistance exercise of an appropriate intensity, based on a 10 RM can then be prescribed to stress the tissue beyond what is typically experienced and at a level that will promote change in muscle tissue. Physical activity in the form of walking may be encouraged through the use of a pedometer to monitor required levels of physical activity to promote conditioning of the cardiopulmonary system. The standard of a percentage of V· O2 max can be used to determine the appropriate level of response, monitored through vital signs and/or pulse oximetry.
42Strengthening Exercise Prescription in Geriatrics 60% 1RM minimal overload or 15 RM necessary for muscle adaptation in untrained individuals80% 1 RM X 10 reps is preferred, especially for concerns with pain or joint forcesa gradual increase beginning at 50% of 1RM for an individual who has been sedentaryStrengthening exercise would be the first type of exercise prescribed
43Remember…..Slow walking or lifting light weights such as 2 lb ankle weights to stimulate the quadriceps will NOT appreciably improve aerobic capacity or strength in most individuals.
46Progression to PowerAfter an older adult can do 2 sets with good form and no painIncorporate training to increase powerMove quickly through concentric phase followed by a slow and controlled lowering of the loadInitial loads at 20% 1RM and progress towards 60% 1RMPower found to be a strong predictor of loss of function, e.g. climbing stairsWhite paper exercise.J. Blackwood
47Guidelines for ex RX with CV Consider: intensity, mode, frequency, duration, and progressionMonitor: HR, BP, SaO2, ECG, BORG scale (RPE), estimated VO2 max, MET levels.J. Blackwood
49Injuries? Many authors demonstrate safety of high intensity exercises Requires 1:1 supervisionMonitoring of vitalsThere are no absolute contraindications for strengthening exercisesCare must be taken to have the person use proper form and avoid holding his or her breathThere are no absolute contraindications for strengthening exercises. Although care must be taken to have the person use proper form and avoid holding his or her breath, there have been very few reported problems with strength training.
50Specificity of training Specificity leads to the concepts of functional strengthening, i.e. strengthening a movement rather than a muscle.Simply walking may not improve the patient's walking above a critical threshold if there is no overload or challenge present.Overload the patient's gaitIncrease speed of walking, ambulate on uneven surfaces, head turns while walking, carry a large object, obstacle course.
51Progression of a functional exercise program is obtained by moving from simple movements to more complex movements,normal speed to either quicker or slower movements,stable surfaces to unstable or compliant surfaces,eyes open to eyes closed, andan emphasis on form to an emphasis on intensity and the working over from base of support to working outside the base of support

63Types of muscle contractions Analyze functional activities to identify the type of muscle contraction neededTrunk muscles stabilizers isometric contractionGait cycle 60% eccentric contractionse.g. dorsiflexors contract eccentrically at heel strike to foot flat, gluteus medius contracts eccentrically during midstanceSlowing the speed of the movement overloads the activity, e.g. sit down as slow as possible
64Eccentric contraction training for gluteus medius to improve gait If right gluteus medius is weak have a patient stand on the right leg while performing a rapid contraction of the left gluteus medius against an elastic band causes the right gluteus medius to contract both rapidly and eccentrically (similar to the way it is used in gait)
65Aerobic/Endurance Training Endurance training, which is the best exercise to increase/maintain mitochondrial concentration with aging, has generally resulted in relatively small functional benefits, e.g. in nursing home patients, older adults with Parkinson’s diseaseStrength and aerobic training attenuate muscle wasting and improve resistance to the development of disability with aging.

66Calculating Target Heart Rate for older adults Traditional formula(60% to 80%) × [220 − age]May underestimate the heart rate loadKarvonen methodSolution is to use a percentage of heart rate reserve[(60% to 80%)×(220− age− resting heart rate)] + resting heart rate
68StretchingA 60-second hold is required to achieve a long-term effect in older adults 65+ years4 reps X 60-second hold5 to 7 days a weekStatic stretching is preferred to dynamic stretching to improve muscle length.Loss of joint ROM is not just from muscle-tendon complex and other soft tissue, e.g. joint capsule or ligaments, fascia, and connective tissue.
69Measurement of functional ROM: Two items from Senior Fitness Test Chair sit and reach testBack scratch testChair sit and reach testInstructions for participantSit close to the front of the seat with the crease between the top of the thigh and the buttocks on the edge of the seat.Have one leg extended straight with the heel on the floor and the foot flexed at 90 degrees to the leg.Have the other leg bent at right angles at the knee with the foot flat on the floor.Place one hand over the other with finger tips level.Slowly reach forward as far as you can towards the toes in the outstretched leg.Do not bounce forward.Hold the maximum reach for 2 seconds.Try with the other leg extended and see which one is able to allow the greater reach.Back scratchPlace one hand over the same shoulder with the palm touching the back and reach down the back.Place the other hand up the back from the waist with the palm facing outwards. Reach up the back.Point the middle fingers of each of hand towards each other.Try and touch the fingers of each hand in the middle of the back.Do not bounce the arms towards each other.Do grasp the fingers and pull the hands together.Try two warm ups with the arms in opposite positions to determine the preferred side for reaching over the shoulder.toolboxes.flexiblelearning. net.au/demosites/series8/ 805/fit_tb/fit011_1_lr10/fit0 11_1_lr10_1_6.htmtoolboxes.flexiblelearning. net.au/demosites/series8/ 805/fit_tb/fit011_1_lr10/fit0 11_1_lr10_1_5.htm
72For example, while attempting to stretch the hamstrings by using trunk forward flexion, one may inadvertently be causing flexion forces to the lumbar spine. An alternate method may be to lie supine and use a rope on the foot to pull the lower extremity into a straight leg raise
76Plyometrics (“Plyos”) exercise Use the stretch reflex of the muscle spindle and the elastic energy that is stored in a stretched muscle to enhance an immediate reciprocal contraction in that muscle.Usually consists of an eccentric (lengthening) contraction followed by a concentric (shortening) contraction of the same musclesThe ability to increase the explosiveness (speed & power) of the muscle contractionMay improve bone formationPlyometrics, also known as "jump training" or "plyos", are exercises based around having muscles exert maximum force in as short a time as possible, with the goal of increasing both speed and power.
