KCE Reports 88 Chronic Fatigue Syndrome 53<br />
GRADED EXERCISE THERAPY (GET)<br />
Graded exercise therapy should be delivered by a suitably trained GET therapist with<br />
experi<strong>en</strong>ce in CFS, under appropriate clinical supervision and preferably one-to-one.<br />
GET should include the establishm<strong>en</strong>t of a baseline followed by planned increases in<br />
duration of low int<strong>en</strong>sity physical activity, followed by gradual increases in int<strong>en</strong>sity<br />
leading to aerobic exercise (which increases the pulse rate). It should be based on<br />
curr<strong>en</strong>t level of activities and daily routines and on the pati<strong>en</strong>t’s own goals. Both pati<strong>en</strong>t<br />
and healthcare professional should recognise that it may take weeks to years to achieve<br />
these goals.<br />
Although graded exercise therapy is recomm<strong>en</strong>ded for CFS pati<strong>en</strong>ts, exercise can<br />
exacerbate symptoms in chronic fatigue syndrome and provoke post-exertional malaise<br />
if too-vigorous exercise/activity is prescribed. Designing and implem<strong>en</strong>ting an exercise<br />
programme for chronic fatigue syndrome have to take into account this adverse effect<br />
in order to deliver a programme with no detrim<strong>en</strong>tal effects on the pathophysiology of<br />
the condition, in particular to guarantee treatm<strong>en</strong>t compliance. 137<br />
Guidelines to implem<strong>en</strong>t such a graded exercise therapy programme are proposed both<br />
by Wallman et al (2005) 138 and by Nijs et al. (2008). 137<br />
EXAMPLE OF STRUCTURED PROTOCOL FOR EXERCISE SESSIONS<br />
Wallman et al. (2005) 138 have described the graded exercise program used in their<br />
randomised controlled trial. 82 According to the authors, this program has be<strong>en</strong><br />
successfully implem<strong>en</strong>ted in a clinical practice. It includes the concept of pacing and is<br />
aimed at non-bed-bound, sed<strong>en</strong>tary pati<strong>en</strong>ts with CFS, as well as those already<br />
undertaking minimal aerobic exercise (i.e., no more than three sessions per week of 20<br />
minutes’ duration). The protocol described here was never associated with any major<br />
relapse, helped to prev<strong>en</strong>t CFS pati<strong>en</strong>ts overdoing physical activity and can halt further<br />
deconditioning. The exercise sessions are in addition to normal activities, and some<br />
initial aches and pains are usual wh<strong>en</strong> beginning exercise for the first time.<br />
Pati<strong>en</strong>ts have:<br />
• to follow their heart rate during exercise sessions (checked with a<br />
heart rate monitor or by assessing pulse rate)<br />
• to rate their perceived exertion (RPE - Borg scale in Table 4) on<br />
completion of each exercise session in order to average values each<br />
fortnight. The averaged RPE value forms the basis for determining the<br />
duration of future exercise sessions<br />
• to monitor progress over time and link poor performance with a<br />
possible emotional or physiological ev<strong>en</strong>t (exercise diary).<br />
