School of Allied Health, Exercise and Sports Sciences 3 SCHOOL OF EXERCISE SCIENCE, SPORT & HEALTH 3 Diagnosis Of Multiple Sclerosis ■ Based on presenting signs/symptoms in combination with medical imaging and laboratory testing. ■ Typical diagnostic tests include: Medical history: Assess past and present signs/symptoms. Neurological exam: Assess health of nervous system. MRI: Can determine spatial and temporal distribution of lesions. Evoked potential response: Measure electrical response to sensory stimulation (visual, auditory, somatosensory). □ Cerebrospinal fluid analysis: Assess for immunoglobulin level and oligoclonal bands. □ Blood tests: To rule out other diseases. □ McDonalds Criteria □ □ □ □ School of Allied Health, Exercise and Sports Sciences 4 SCHOOL OF EXERCISE SCIENCE, SPORT & HEALTH 4 Clinical Course Of Multiple Sclerosis ■ Relapsing remitting MS (RRMS; 85%): Characterised by periodic exacerbations followed by full or partial recovery of deficits. ■ Primary progressive MS (PPMS; 10%): Characterised by continuous disease progression from onset with little or no plateaus or improvements. ■ Secondary progressive MS (PPMS; ??%): Initially characterised by relapsing-remitting course followed by primary-progressive course. ■ Progressive relapsing MS (PRMS; 5%): Characterised by a progression from onset with distinct relapses superimposed on the steady progression. School of Allied Health, Exercise and Sports Sciences 5 SCHOOL OF EXERCISE SCIENCE, SPORT & HEALTH 5 Clinical Course And Prognosis Of Multiple Sclerosis ■ Extent of disability is related to clinical course. ■ Life expectancy is minimally reduced in MS. ■ Most people with MS die from many of the same conditions as non-MS peers (e.g. cancer and heart disease).

Physical Therapy, 87(5); 545-555. 17 SCHOOL OF EXERCISE SCIENCE, SPORT & HEALTH 17 Response To Exercise ■ Individuals with MS generally have lower VO2, strength, balance, mobility compared to a healthy persons. ■ Autonomic dysfunction: □ Thermoregulation: Impaired sweat response. □ Cardiovascular: HR and BP response to exercise may be blunted. • RPE can be used in addition to HR to evaluate exercise intensity. ■ Fatigue: Common in individuals with MS with mild-to-moderate disability. □ Adjust exercise time and intensity as appropriate ■ “Uhthoff phenomenon”: □ Transient (<24 h) worsening of neurological symptoms, most commonly visual impairment, associated with exercise and elevation of body temperature. □ Use cooling strategies and adjusting exercise time and intensity as appropriate. ■ Close monitoring is needed due to unpredictability of symptoms. School of Allied Health, Exercise and Sports Sciences 18 SCHOOL OF EXERCISE SCIENCE, SPORT & HEALTH 18 Pre-Screening And Assessment ■ Performed using ESSA Adult Pre-exercise Screening Tool. ■ History and physical exam: Assess for indicators that will impact the exercise prescription and that can be improved with exercise. □ Review medical history and medications. □ Current symptoms: • Balance. • Flexibility. • Strength. • Vision. • Fatigue/endurance. • Gait abnormalities. School of Allied Health, Exercise and Sports Sciences 19 SCHOOL OF EXERCISE SCIENCE, SPORT & HEALTH 19 Exercise Testing In Multiple Sclerosis ■ Useful for baseline measures for future comparisons of effectiveness of exercise training. ■ Provides information on individual responses and exercise tolerance. ■ Balance, mobility, and gait evaluation: □ □ □ □ □ Functional reach test, tandem stance, single limb stance. 360 turn. Chair sit-to-stand, Timed Up and Go, Tandem walk. Berg Balance Scale. 10-m walk test at a comfortable walking speed. School of Allied Health, Exercise and Sports Sciences 20 SCHOOL OF EXERCISE SCIENCE, SPORT & HEALTH 20 Exercise Testing In Multiple Sclerosis ■ Cardiovascular testing: □ Consider cycle ergometer if ambulatory impairment exists. □ Treadmill if safe gait/balance is not an issue. □ Watch for indications of overheating and fatigue; electric fans, fluid replacement, and cooler room temperatures help. □ Apply low-level protocols for most due to deconditioning. □ Watch for attenuated HR and BP response, especially if autonomic dysfunction has been diagnosed. ■ Muscular strength testing: □ Standard testing typically OK. □ 1RM can be used, but modify if significant weakness. ■ Flexibility: □ Use goniometer □ Can be quite inflexible due to disease progression and level of spasticity. School of Allied Health, Exercise and Sports Sciences 21 SCHOOL OF EXERCISE SCIENCE, SPORT & HEALTH 21 Goals For Exercise In Multiple Sclerosis ■ Primary aim is to maximise physical function and reduce disability or at least slow progression of disability. ■ General goals for exercise in people with Multiple Sclerosis are: Increase or maintain physical activity levels. Maintain ability to perform ADLs. Reduce impact of symptoms. Provide general health benefits to reduce to deconditioning and secondary comorbidities. Note goals should reflect □ Improve QOL. what will have the biggest □ Enhance mental health. impact for the patient □ □ □ □ School of Allied Health, Exercise and Sports Sciences 22 SCHOOL OF EXERCISE SCIENCE, SPORT & HEALTH 22 Recommendations For Balance, Mobility, And Gait Training ■ Balance, mobility, and gait training and mobility is important in MS. ■ Static, dynamic, and balance training during functional activities should be included. ■ Exercises may include a variety of challenging activities: □ Bosu ball, large balls, and so on. School of Allied Health, Exercise and Sports Sciences 23 SCHOOL OF EXERCISE SCIENCE, SPORT & HEALTH 23 Recommendations For Cardiorespiratory Exercise Programming ■ Guidelines for healthy adults apply to MS within the limits of symptoms. ■ Frequency: 3-5 days/week. ■ Intensity: 40-70% MHR or RPE of 11-14. ■ Time: Increase exercise time initially to min of 10 mins before increasing intensity. □ Progress to 20-60 min. □ In individuals with excessive fatigue, begin with lower intensity and discontinuous bouts of 10-15 mins. ■ Type: Walking, cycling, or swimming dependent on the individual’s clinical presentation. □ Stationary cycle, recumbent cycle, or arm ergometer are safer modes for individuals with more advanced MS. School of Allied Health, Exercise and Sports Sciences 24 SCHOOL OF EXERCISE SCIENCE, SPORT & HEALTH 24 Recommendations For Resistance Exercise Programming ■ Recommendations for resistance exercise in healthy adults may be applied to individuals with MS. ■ Frequency: 2-3 days/week (never 2 consecutive days). ■ Intensity: 40-80% of 1-RM. ■ Volume: Initially, 1-2 sets of 8-12 reps until fatigue and progress. □ Increase rest time between sets and exercises (e.g. 2-5 mins) for weaker muscle groups or easily fatigued individuals as needed to allow for full muscle recovery. □ Focus on large antigravity muscle and minimise total number of exercises performed. ■ Type: Body weight, machines, free weights as tolerated and symptoms allow. ■ Resistance exercise in a pool can be beneficial. School of Allied Health, Exercise and Sports Sciences 25 SCHOOL OF EXERCISE SCIENCE, SPORT & HEALTH 25 Recommendations For Flexibility And Joint ROM Exercise Programming ■ Flexibility and ROM exercises are important for management of spasticity. ■ Frequency: 5-7 days/week; 1-2 sessions/day. ■ Intensity: Full extension, flexion, rotation, or stretch to the point of slight discomfort. ■ Time: Hold stretches for 30-60s; 2-4 reps. ■ Type: Slow static stretches for all major muscle groups should be performed.

(2018) 27 SCHOOL OF EXERCISE SCIENCE, SPORT & HEALTH 27 Summary Special Considerations For Exercise ■ Individualised assessment Mobility, strength, balance and functional capacity ■ Stage and Type of MS ■ Heat sensitivity Hydrate, clothing consideration, hydro? And outdoor… ■ Fatigue consideration ■ Safety ■ Cognitive loads School of Allied Health, Exercise and Sports Sciences 28 SCHOOL OF EXERCISE SCIENCE, SPORT & HEALTH 28 Considerations For Exercise ■ In spastic muscles, increase the frequency and time of stretching exercises. □ Muscles and joints with significant tightness or contracture may require longer duration (several minutes to several hours) and lower load positional stretching to achieve lasting improvements. Note these general considerations ■ Whenever possible, incorporate functional activities into the exercise program to promote optimal carryover. □ E.g. Stairs climbing, sit-to-stand, etc. ■ Due to cardiovascular dysautonomia use RPE in addition to HR and BP to evaluate exercise response. □ Blunted HR and BP responses may not provide accurate measures of intensity. School of Allied Health, Exercise and Sports Sciences 29 SCHOOL OF EXERCISE SCIENCE, SPORT & HEALTH 29 Special Considerations For Exercise ■ During an acute exacerbation of symptoms, decrease the dose of exercise based on tolerance (symptom-limited prescription). □ If severe, focus on maintaining functional mobility and/or focus on activities such as cardiorespiratory exercises and flexibility. ■ Fatigue is common in MS but can improve with exercise training. □ Help clients understand the difference between MS-mediated fatigue and exercise-induced fatigue. □ Tracking the effects of fatigue may be helpful using an instrument such as the Modified Fatigue Impact Scale. Note the special considerations ■ Heat sensitivity is common in MS. □ Use of fans, evaporative cooling garments, and cooling vests can increase exercise tolerance and reduce symptoms (↑of 0.5°C core temp can impair nerve conduction). School of Allied Health, Exercise and Sports Sciences 30 SCHOOL OF EXERCISE SCIENCE, SPORT & HEALTH 30 Summary ■ The diagnosis of MS may involves a range of electrophysiological and neuroimaging techniques as well as a physical exam. ■ Treatment of MS aims to slow progression and reduce symptoms through anti-inflammatory agents, such as interferon and corticosteroids. ■ Goal for exercise is to enhance or maintain daily activity levels and/or improve functional capacity, mobility, quality of life, and mental health. ■ There are no exercise training-specific guidelines for those with MS. ■ Adjust exercise prescription to avoid excessive fatigue to ensure client safety as disease progresses.
