Disseminated Sclerosis – Rest-Exercise Therapy – A Progress Report

Russell & Palfrey. Physiotherapy 1969; (August) p308 Subjects: 69; duration: 2-8 yrs Intervention: rest-exercise therapy (REP)

Following 20 min of rest - “press-ups” or UE weightlifting exercises with maximal effort to fatigue to cause flushing of the face (goal: hyperemic response in the blood circulation of the upper spinal cord and brain stem)

Outcome Measures Comparison of level of compliance with the REP with change

in disability grade (scale 1-6)

Conclusion: “for those who have the persistence and enthusiasm necessary

to carry out the programme advised, the future course of their disseminated sclerosis is likely to become benign”

Role of Cardiovascular Fitness in Multiple Sclerosis: A Pilot Study

Schapiro et al. J Neuro Rehab 1988; 2(2): 43-9

• Matched-control pre/post-test design (n=48)• Intervention:

– Schwinn Air-Dyne ergometer (16 wk, 4-5/wk, 15-30 min, 65-85% HRpeak)

• Conclusions– No increase in disability after 16 wks training– Modest improvement in fitness (peak workload)

Impact of aerobic training on fitness and quality of life in MSP

Petajan, Gappmaier, White et al. Annals of Neurology 1996; 39:432-41

• Randomized, controlled repeated measures design

• Subjects: (n=46, EX=21, CG=25)– EDSS 3.3 (1.0-6.0)– 15 M, 31 F; 40.1 a (23-56)

• Intervention:– UE/LE cycle ergometry (Schwinn-AirDyne)

• 40 min @ 60% VO2max

• TIW, 15 wks

Impact of aerobic training on fitness and quality of life in MSP

Petajan, Gappmaier, White et al. Annals of Neurology 1996; 39:432-41

• Outcome Measures/Results– Training compliance 97% (91-100%)– Neurological Status

• EDSS – no change • FS (no change except ↑ bowel and bladder function

(p<0.05)• ISS (EX 9.0 to 6.8; CG 8.1-8.3; ns)

– VO2max: +22% EX (+1% CG) (p<0.01)– WLmax: +48% EX (+12% CG) (p<0.01)

• Magnitude of improvement not related to level of neurological impairment - EDSS ≤ 3.5 (n=14) ≈ EDSS > 3.5 (n=7)

Impact of aerobic training on fitness and quality of life in MSP

Petajan, Gappmaier, White et al. Annals of Neurology 1996; 39:432-41

• Conclusions– Aerobic training had no negative impact on

neurological status

– MS patients may reap similar benefits from aerobic conditioning as individuals without MS

• increased aerobic capacity • increase in muscle strength• favorable changes in body composition and lipid profile

Page 13: Exercise and MS: History, Research Evidence, and Clinical Considerations · Exercise and MS: History, Research Evidence, and Clinical Considerations Eduard Gappmaier, PT, PhD ...

Aerobic Training StudiesSummary of Research Evidence

• 21 “aerobic” training studies• 9 “RCT” (only 6 with n ≥ 10/grp; only 3

of those measured max exercise capacity)

• Not a “ton of research” BUT ….

Resistance Training StudiesCritics may rightfully argue:

• Few studies!• Many limitations!

• Lack of controls• Small n• Inconsistent results limit conclusions• Short-term interventions

• Need long-term studies with repeated evaluationsReversal of disuse atrophy ≈ adaptive capacity ≈ overuse

• Studies to unspecific• Need to explore relationship ofDegree of impairment ≈ intensity of training stimulus ≈ training

adaptation• Nature of adaptations – neural vs. peripheral (metabolic vs.

structural)• Insufficient evidence to exclude possibility of

detrimental effects!

Show me the evidence!
