One of the first questions (early on in the disease) is to ask….
What are you currently doing to manage your health? What exercise do you currently undertake? Is there anything that is putting you off exercising? Lets see how I can help as exercise has proven to be beneficial.

Potential Impact of Physical Activity on Brain Health and the Immune System
Mediates processes:
• Neuroprotective,
• Neuroregenerative,
• Adaptive (Neuroplasticity)
enhancement of neurotrophic factors
enhance stress resistance
influences balance of pro/anti-inflammatory response
(Gold et al 2003; Heesen et al 2003; White et al 2006; White and Castellano 2008; Golzari et al. 2010)
Freeman&Gear/MSTrust/2015
Freeman&Gear/MSTrust/2015
Guideline Recommendations: for people with mild to moderate MS
• Resistance Exercise: 2-3/week at moderate intensity (60-80% 1RM, 10 – 15 repetitions, 1-3 sets), minimum 8 weeks
Resistance Exercise: 2x/week moderate intensity (60-80% 1RM, 10 – 15 repetitions, 1-3 sets) minimum 8 weeks Aerobic Exercise:
2-3/week mod intensity (60-80% max HR) 30 minutes minimum 4 weeks
Freeman&Gear/MSTrust/2015
1.4 Modifiable risk factors for relapse or progression of MS 1.4.1 Exercise • Encourage people with MS to exercise. Advise them that
regular exercise may have beneficial effects on their MS and does not have any harmful effects on their MS.
1.5 MS symptom management and rehabilitation 1.5.8 Fatigue Consider a comprehensive programme of aerobic and moderate progressive resistance activity combined with cognitive behavioural techniques for fatigue in people with MS with moderately impaired mobility (an EDSS[5] score of greater than or equal to 4) Mobility or fatigue • 1.5.11Consider supervised exercise programmes
involving moderate progressive resistance training and aerobic exercise to treat people with MS who have mobility problems and/or fatigue.
• 1.5.13 Encourage people with MS to keep exercising after treatment programmes end for longer term benefits (see Behaviour change: individual approaches NICE public health guideline 49).
• 1.5.14 Help the person with MS continue to exercise, for example by referring them to exercise referral schemes.

Designing exercise programmes Considerations:(1)
1.Individual differences
2.Specificity
3.Overload
4.Progression
5.Reversibility
6. Ms Specific Issues www.sportsmedicine.com
Slide from Dalgas, RIMS, 204 Freeman&Gear/MSTrust/2015
1. Individual Differences: “People respond differently to exercise because of differences in size and shape, genetics, past experience, chronic conditions, injuries and even gender”
2. Specificity “To become better at a particular exercise or skill, it is necessary to perform that exercise or skill”
3. Overload
“A greater than normal stress or load on the body is required for training adaptation to take place”
Can be done by increasing intensity, duration and/or frequency
Fleck & Kraemer; Designing Resistance Training Programs
4. Progression of overload
“There is an optimal level of overload that should be achieved, and an optimal time frame for this overload to occur” Freeman&Gear/MSTrust/2015

Freeman&Gear/MSTrust/2015
Specific Considerations for Physiotherapy Practice
• Early intervention is beneficial. Timely referral requires good communication with MS nurses and Neurologists
• Exercise programmes of moderate intensity at 3 times / week are well tolerated with no apparent negative affects
• The principles of frequency, intensity, specificity and progression is required to optimise outcome, regardless of physiotherapy intervention.
• Before designing programme; assess the individual (physical activity patterns / physical effects of MS)
• Start conservatively and establish realistic expectations (30% rule)
• Supervise programmes to ensure workload progression
Freeman&Gear/MSTrust/2015
General Summary
• Scientific evidence demonstrates exercise is effective and safe
• People with MS remain less physically active
• There are many barriers and facilitators of exercise
• Adherence to exercise reduces over time
• Behaviour change interventions are required
• Crucial to translate this knowledge into practice

Section Overview
• Barriers to exercise for PwMS
• Development of Community Leisure Centre Based Exercise Classes for PwMS: how we addressed the barriers
Workshop:
• Local Models of Exercise Service Delivery
• Local Barriers
• Beating the Local Barriers
Freeman&Gear/MSTrust/2015
Do PwMS Value Exercise? • Exercise is ranked above conventional therapies such as physiotherapy (O’Hara et al 2000) •41% report exercise as the area about which they most commonly want advice (Somerset et al 2001) Top three exercise barriers, regardless of gender 1. Too tired 2. Impairment 3. Lack of time (Survey n = 417, Asano et al 2013)
Freeman&Gear/MSTrust/2015
Barriers: Fatigue • Among most common and devastating of MS symptoms
• Affects various components of health and wellbeing
• Characteristics of MS fatigue vary: Valuable for individual to learn to select appropriate strategies
• Exercise and education have a stronger effect on reducing fatigue compared to the two most commonly prescribed fatigue medications (i.e., Amantadine and Modafinil)
Asano & Finlayson 2014 Pilutti et al 2013
Freeman&Gear/MSTrust/2015
Barriers: Impairments impacting on ability to achieve desired levels of exercise
•Fatigue •Weakness •Poor co-ordination •Spasticity •Sensory disturbance •Visual disturbance
•Bladder & bowel dysfunction •Communication difficulties •Pain •Vertigo •Cognitive difficulties •Depression & anxiety
Variable, unpredictable, multi-factorial, generally progressive…. constantly changing over a lifetime
Freeman&Gear/MSTrust/2015
Other factors impacting on ability to exercise
Emotional • Dependence on family / community support • Decreased motivation • Coping skills Accessibility • Equipment • Location(s) • Expertise
• Time of day Freeman&Gear/MSTrust/2015
MS Specific Considerations: Heat Sensitivity
In demyelinated fibres: Increase of 0.5 degrees slows nerve impulse conduction Further increase ultimately blocks nerve impulse conduction Symptom exacerbation is proportional to degree of temperature elevation Rises in core temperature are greater in endurance programmes than in resistance programmes (White 2013; Skjebaek et al 2013)
Freeman&Gear/MSTrust/2015
Heat Sensitivity: Management strategies
• -ensure the exercise environment is not too hot
• -drink cold water before, during and after exercise
• -pre-exercise cooling can be beneficial (cool shower)
• -wear light clothing during the activity
• -work at a pace that does not allow overheating
• -build in rest breaks as needed
• -post exercise cooling (cool shower or bath, cold packs)
• -consider interval training
• -consider water training (water dissipates heat 25x faster than air)
Freeman&Gear/MSTrust/2015
Transient neurological symptoms
Common (e.g. fatigue, visual, sensory {~40%}
disturbance) In ~ 85% of people these resolve / return to normal within 30 – 60 minutes, or more rapidly with cooling (Smith et al 2006,White et al 1997)
• Start slowly - build up intensity & duration • “Listen to your body” - monitor the impact of
exercise on changing symptoms • “2 hour rule”
Freeman&Gear/MSTrust/2015
Community Leisure Centre Based Classes Shetland Islands, Scotland
•One of the highest incidences of MS in the world (Visser et al 2011)
•High exercise drop-out rates (Kayes et al 2011)
•PwMS said “they wanted to exercise and to use leisure facilities, but that
local mainstream leisure facilities did not meet their needs”
•The local leisure provider keen to have PwMS but required support
•Aim: sustainable specialist MS exercise service in the community
•Barriers to exercise identified in literature and local patient questionnaire
•Required a cultural shift
Freeman&Gear/MSTrust/2015
Identifying Local Barriers to Exercise
Gyms can be
intimidating if you are not
super fit
Required culture shift for PwMS, Physios, & Leisure Provider
Previous experience of not coping
Local Service MS Questionnaire
Freeman&Gear/MSTrust/2015
Extrinsic Barriers: Access ‘I was so exhausted after propelling my wheelchair into the building that I couldn’t do any exercise. I just went home again.’ ‘I was really tired after the long walk from the car park to the main entrance. I knew after that I wasn’t going to manage the stairs down to the MF room.’
Freeman&Gear/MSTrust/2015
Building Access: Solutions • Open up door at rear of building, near car park
• Level access, straight into exercise room
• NHS funded chairs for those waiting
• Accessible toilets < 10m
• Pay in exercise room
Freeman&Gear/MSTrust/2015
Extrinsic Barriers: Safety • Risks assessed for whole service and each individual participant
• Exercise instructors trained with: Later Life, Oxford Brooks University & NHS Shetland
• Mangar Elk for those unable to get up from floor: training for instructors
• Study chairs provided
• Sturdy tables brought in
• Grab rails for exercise
• Criteria for referral agreed
• Direct referral back to neurophysio

Extrinsic Barriers: Transport
Voluntary Sector: •MSS car + driver •Red Cross (10 mile radius) •WRVS 14p / mile
Lifts with friends Some PwMS still cannot access transport to the classes: they need a different model
10 mile radius
Freeman&Gear/MSTrust/2015
• Fatigue assessed by MDT and education on fatigue offered
• Fatigue levels also self assessed before and after 3 months exercise
• Exercise and progression rates individually tailored
• Participants encouraged to rest as required; chairs available throughout room
• Half time called for each exercise station; rest if required
• Rest break for all half way through class
• Participants rate their ability to self pace on referral to leisure centre
• Initial questionnaire asked preferred time of day
Intrinsic Barriers to Exercise: Fatigue
Freeman&Gear/MSTrust/2015
Tackling Intrinsic Barriers to Exercise: Impairment
• Multiple individual impairments, esp bowel / bladder dysfunction & cognition low self efficacy
• Previous experience of not coping in mainstream exercise groups
• Individual coping strategies for impairments devised during physio led individual exercise sessions, then group sessions
• Referral form to leisure centre completed by participant + physio. Impairments and coping strategies listed on form
• Small group supported each other to integrate into larger leisure centre group. This approach may help to overcome anxieties
Freeman&Gear/MSTrust/2015
Referral Process
Participant assessed by physio as meeting inclusion / exclusion criteria for exercise classes
Introduced to exercise programme in physiotherapy
?Confident and able to attend leisure centre classes?
NO
Physio led exercise class to gain ability, strategies and confidence
to attend leisure centre
Refer whole physio led group to larger leisure centre group
YES
Refer individual directly to leisure centre classes
Participant or exercise instructor can refer directly back to physio if condition
changes
Freeman&Gear/MSTrust/2015
Bowel / bladder
dysfunction
• Gym room with toilets immediately adjacent
• Break half way through
• Warm-up exercises include pelvic floor exercise
Communication / cognitive difficulties
• All information (e.g. personalised exercise diaries, class times, venue, directions) provided in large font 14 clear print in addition to verbal information.
• Large pictures of each exercise
at each station • ‘Buddy’ system for exercise
class
• Initial text reminders
Visual Disturbance
• Ensure adequate lighting
Adjustments by Leisure Provider
Freeman&Gear/MSTrust/2015
Heat Sensitivity • Negotiate with leisure centre re room temperature • Advised re loose light clothing • Rest breaks built in
• Cooled water available throughout and served at break
time. Feedback from participants (3 month audit) was that this was the strategy that worked best for them
Freeman&Gear/MSTrust/2015
Lack of Time • Actual time commitments do not
predict perceived lack of time for physical activity (Heesch & Masse 2004)
• Lack of time may really be lack of prioritisation
• Education about benefits of exercise to encourage prioritisation • Initial questionnaire asked
participants about their preferred days / times for exercise classes. All groups requested week days, late morning or early afternoon.
Freeman&Gear/MSTrust/2015

Aim: Self Efficacy
Self-efficacy: one's belief in one's ability to succeed in specific situations or accomplish a task

Evaluation: web–based physiotherapy • Pilot RCT (N = 30) • Moderate MS ( EDSS 5 – 6.5) • 12 weeks individualised web-based physiotherapy, 2/week • Online exercise diaries monitored; participants telephoned
weekly, exercise programmes altered remotely
Results • Web-site easy to use, convenient, and motivating • No significant difference between groups for mobility,
balance, symptoms or depression; except in MSIS-29 • Average log in 1.3/week (↓ from 2.1 to 0.9 over the 12
weeks)
• N.B. Of the 138 invited only 38 wished to participate (and a further 8 didn’t meet criteria) Freeman&Gear/MSTrust/2015

Workshop
Describe models of exercise services for people with MS that are working well in your local area
Freeman&Gear/MSTrust/2015
Models of Exercise Delivery: examples highlighted by participants in the workshop
• Partnership between physio and the local gym (partly sponsored by cricket club)
• Activity for Health - council run Charity run exercise groups
Freeman&Gear/MSTrust/2015
Workshop
What are the barriers to exercise for people with MS in your local area?
Freeman&Gear/MSTrust/2015
Barriers: examples highlighted by participants in the workshop
• Mixed ability - require too many groups • Gym classes - worried how people perceive them • Transport • Work • Fatigue • Cognition / memory • Patients become demotivated • Lack of specific equipment • Lack of awareness of facilities / groups / opportunities In NHS • Physios don't have exercise instructor skills • Limited time slots in local gyms • Inequity of service provision
Freeman&Gear/MSTrust/2015
Workshop
Note any solutions to these barriers on your sticky notes and stick them on the relevant flip chart
Freeman&Gear/MSTrust/2015
Solutions: suggestions by participants in the workshop
Freeman&Gear/MSTrust/2015
For transport difficulties: • Car share scheme • Volunteer driver bureau • Approach MS Society
Training solutions: • Physio training CoS, e.g. Physio UK • Council REP level 4 exercise instructors could impart training • Knowledge and education for providers
For demotivation: • Keep patients challenged • Alternate b/w programmes • Competition b/w patient
groups to encourage exercises
For lack of awareness of facilities: • Education for GPs, local gyms • In service enhancement • Relationships with local sources • GP referrals - more proactive
Funding solutions: • Big lottery • Corporate funding • Charities - e.g. Red Cross, MS
Society, Age Concern
Other approaches/ideas: suggestions by participants in the workshop
• Riding is good exercise
• More individualised programmes
• Seated exercises; Thai chi, yoga
• Exercise buddy
• Open gym sessions in therapy centres
• Educating employers
• Councils having specialised areas for all service users with neurological disorders
• Appropriate referrals
