Objectives § Understand the importance of exercise and
activity for living well with PD
§ Recognize current evidence and gaps in knowledge concerning exercise and activity benefits
§ Appreciate evidence suggesting vigorous activity might have neuroprotective benefits

![Page 5: PD ExpertBriefing The Effects of Exercise on PD · Exercise: Review underlying issues with a professional ! targeted exercise to prevent / reduce musculoskeletal and cardiovascular](https://reader034.vdocuments.site/reader034/viewer/2022050612/5fb2d6a8060001246165a144/html5/thumbnails/5.jpg)
‘Exercise’ vs. ‘Activity’ Ø Exercise refers to
specific regimens to improve specific underlying problems (e.g., balance, gait, flexibility etc.); often is supervised
refers to any movement of the body that uses energy (e.g., walking, hiking, gardening)

Which Is More Important?
§ Exercise – helps correct specific underlying problems that interfere with daily function and lead to falls
§ Activity keeps you going, and is critical after supervised exercise
§ Activity, and particularly vigorous activity, is just as important as structured ‘exercise regimens’

Focus of Exercise § Cardinal signs
– Rigidity – Tremor – Bradykinesia – Postural instability
§ Other impairments – Musculoskeletal (e.g. Range of motion, flexibility,
strength) – Cardiovascular (e.g., Endurance) – Balance and Gait – Non-motor (e.g., depression, cognition, sleep)

![Page 14: PD ExpertBriefing The Effects of Exercise on PD · Exercise: Review underlying issues with a professional ! targeted exercise to prevent / reduce musculoskeletal and cardiovascular](https://reader034.vdocuments.site/reader034/viewer/2022050612/5fb2d6a8060001246165a144/html5/thumbnails/14.jpg)
Cochrane Collaborative – 2012 § Physiotherapy vs. placebo or no Intervention § 39 studies in qualitative synthesis; 1518
participants § 24 studies in quantitative synthesis (meta-
analysis) § Conclusions
– Most short-term benefits were small but of a size that patients would consider meaningful.
14
![Page 15: PD ExpertBriefing The Effects of Exercise on PD · Exercise: Review underlying issues with a professional ! targeted exercise to prevent / reduce musculoskeletal and cardiovascular](https://reader034.vdocuments.site/reader034/viewer/2022050612/5fb2d6a8060001246165a144/html5/thumbnails/15.jpg)
Benefits of Exercise § General physical therapy vs. Control § Exercise vs. Control § Treadmill vs. Control § Cueing vs. Control § Dance vs. Control § Martial arts vs. Control

![Page 16: PD ExpertBriefing The Effects of Exercise on PD · Exercise: Review underlying issues with a professional ! targeted exercise to prevent / reduce musculoskeletal and cardiovascular](https://reader034.vdocuments.site/reader034/viewer/2022050612/5fb2d6a8060001246165a144/html5/thumbnails/16.jpg)
Short Term Improvements … § Gait
– Velocity, step length, two- and six-minute walk
§ Functional reach § Timed Up and Go § Berg Balance Scale § Clinician-rated UPDRS § Absence of evidence in other outcomes does
not necessarily mean lack of benefit
16
![Page 17: PD ExpertBriefing The Effects of Exercise on PD · Exercise: Review underlying issues with a professional ! targeted exercise to prevent / reduce musculoskeletal and cardiovascular](https://reader034.vdocuments.site/reader034/viewer/2022050612/5fb2d6a8060001246165a144/html5/thumbnails/17.jpg)
Findings From Five Additional Recent Studies
§ Flexibility (Schenkman)
§ Aerobic endurance (Schulman)
§ Resistive strengthening (Corcos; Li)
§ Tai Chi (Li)
17
![Page 18: PD ExpertBriefing The Effects of Exercise on PD · Exercise: Review underlying issues with a professional ! targeted exercise to prevent / reduce musculoskeletal and cardiovascular](https://reader034.vdocuments.site/reader034/viewer/2022050612/5fb2d6a8060001246165a144/html5/thumbnails/18.jpg)
Bottom Line Exercise is important
– Long-term exercise habits are necessary because PD is chronic and progressive
– Most appropriate exercise prescription is not yet known
– Many approaches to exercise provide benefits
• Balance training improves balance; strength training improves strength; aerobic conditioning improves aerobic condition!

![Page 19: PD ExpertBriefing The Effects of Exercise on PD · Exercise: Review underlying issues with a professional ! targeted exercise to prevent / reduce musculoskeletal and cardiovascular](https://reader034.vdocuments.site/reader034/viewer/2022050612/5fb2d6a8060001246165a144/html5/thumbnails/19.jpg)
Activity in PD § People with PD (n=699) are 1/3 less active
than older adults generally (n=1,959)
§ Activity levels decline with increasing disease severity
§ In a longitudinal study: daily steps declined 12% and moderate intensity walking declined 40% in a year van Nimwegen et al, J Neurol. 2011;258:2214-21. Cavanaugh et al. J Neurol Phys Ther. 2012;36:51-7.

The ParkFit trial (n = 586) § A two-year study comparing
– physical therapy with a specific emphasis on promoting a physically active lifestyle (ParkFit Program)
– general physical therapy (ParkSafe Program)
§ Included goal setting, overcoming barriers to exercise, recruiting social support, coaching by the physical therapist (PT), and activity monitor with visual feedback for daily activity levels.
§ Lasting change in exercise behavior van Nimwegen et al. BMC Neurol 2010; BMJ 2013;346:f576.

Outcomes - ParkFit
§ 14 day physical activity improved
– 90 min. / week increase with ParkFit
– 30 min. / wk increase with ParkSafe.
§ Walking endurance (6 min walk test) greater at 24 months with ParkFit
van Nimwegen et al BMJ. 2013;346:f576

Bottom Line Regular activity is important
Ø For sedentary people – just get up and move
Ø For more active people – build up to regular, vigorous activity
23
![Page 24: PD ExpertBriefing The Effects of Exercise on PD · Exercise: Review underlying issues with a professional ! targeted exercise to prevent / reduce musculoskeletal and cardiovascular](https://reader034.vdocuments.site/reader034/viewer/2022050612/5fb2d6a8060001246165a144/html5/thumbnails/24.jpg)
Is Vigorous Activity Important?
§ Midlife, regular exercise reduces risk of subsequent PD
§ Exercise reduces cognitive impairment in older people with / without dementia
§ Animal models – physical exercise enhances brain plasticity

Forced Tandem Biking § Comparison of forced pedaling rate vs. self
selected rate during tandem biking § Ten participants, random assignment § Forced rate – 30 percent greater than the
individual's voluntary rate § Three sessions (1 hr each) for ten weeks Ridgel et al, Neurorehabliation & Neural Repair, 2009

Is Exercise Neuroprotective for PD?
Ø Studies are needed in humans but are expensive
Ø Before asking this question, first need to determine: � What is the best dose of aerobic exercise? � Does exercise provide benefits for people prior to
initiation of dopaminergic or other dopamine related therapies?

Exercise And Activity Across Stages of PD
31
![Page 32: PD ExpertBriefing The Effects of Exercise on PD · Exercise: Review underlying issues with a professional ! targeted exercise to prevent / reduce musculoskeletal and cardiovascular](https://reader034.vdocuments.site/reader034/viewer/2022050612/5fb2d6a8060001246165a144/html5/thumbnails/32.jpg)
Strategies: Early-Stage PD Live an active lifestyle with continued involvement at home, work and leisure § Activity: Engage in activities that are fun,
challenge balance, aerobic condition, multi-tasking § Exercise: Think prevention (e.g., prevent future
falls through treating relevant problems) Ø Begin a general exercise program Ø Aerobic Ø Flexibility Ø Strength
32
![Page 33: PD ExpertBriefing The Effects of Exercise on PD · Exercise: Review underlying issues with a professional ! targeted exercise to prevent / reduce musculoskeletal and cardiovascular](https://reader034.vdocuments.site/reader034/viewer/2022050612/5fb2d6a8060001246165a144/html5/thumbnails/33.jpg)
Strategies: Mid-stage PD Stay active!
§ Activity: Vigorous activity that is fun and safe (e.g., walking program, regular dance, kick boxing)
§ Exercise: Review underlying issues with a professional § targeted exercise to prevent / reduce musculoskeletal
and cardiovascular problems and falls § combined training (e.g, balance, strength, flexibility,
aerobic) § Reduce multi-tasking
33
![Page 34: PD ExpertBriefing The Effects of Exercise on PD · Exercise: Review underlying issues with a professional ! targeted exercise to prevent / reduce musculoskeletal and cardiovascular](https://reader034.vdocuments.site/reader034/viewer/2022050612/5fb2d6a8060001246165a144/html5/thumbnails/34.jpg)
Strategies: Later Stage of PD § Stay active within abilities!
– e.g., Walk to get your meds; don’t ask your spouse!!!
§ Activity: Engage in safe fun activities
§ Exercise: May be appropriate to improve balance and even in later stages of PD if able to walk – Few studies have been published from which to
identify guidelines for intervention Ellis et al: Phys Ther, 2009
