to be a consequence “of too much <strong>in</strong>activity”; perform<strong>in</strong>g a muscle biopsy before and after the PACE Trial<br />
would have been a useful and objective measure of mitochondrial abnormality; even m<strong>in</strong>imally <strong>in</strong>vasive<br />
tests to measure lactic acid and mitochondrial function before and after GET would have been useful and<br />
objective measures of the efficacy of GET).<br />
At this po<strong>in</strong>t, the therapists are taught about how the various sessions of “therapy” are to be implemented.<br />
In Phase 1 (cover<strong>in</strong>g sessions 1‐3), therapists must expla<strong>in</strong> what is required of the participant; they must<br />
“engage the participant <strong>in</strong> GET model and expla<strong>in</strong> reversibility” (ie. they are effectively promis<strong>in</strong>g a cure);<br />
therapists must carry out “an assessment of motivation to exercise”; they must carry out a “brief physical<br />
assessment”, but therapists are then told: “objective measures and fitness assessment will already have been<br />
conducted prior to your assessment, and this data passed on to you. You will not receive any actigraphy data”<br />
(another contradiction: “objective measures will already have been conducted” but “you will not receive any<br />
actigraphy data”: the actigaphy data is the only objective measure, so why deny the therapists this<br />
<strong>in</strong>formation? Is the reason because Professor White decided that no actigraphy data for comparison will be<br />
obta<strong>in</strong>ed at the end of the trial?).<br />
Therapists are told that: “Participants will already have undertaken a thorough physical assessment”. A short level<br />
walk<strong>in</strong>g test is far from a thorough physical assessment, and no serial test<strong>in</strong>g was be<strong>in</strong>g carried out. A<br />
patient with <strong>ME</strong>/CFS may be able to perform an activity on one occasion but will typically relapse after a<br />
day or so, hence the need for serial test<strong>in</strong>g. A one‐off test cannot be considered objective, given the evidence<br />
of delayed response to activity seen <strong>in</strong> <strong>ME</strong>/CFS. The fact that the therapist is <strong>in</strong>structed to repeat the level<br />
walk<strong>in</strong>g test after one m<strong>in</strong>ute of recovery, when the heart rate and Borg Scale are to be repeated, is of<br />
doubtful value <strong>in</strong> patients with <strong>ME</strong>/CFS, especially as the correlation between the Borg Scale and the heart<br />
rate is known to be weak <strong>in</strong> any case, yet this appears to be the ma<strong>in</strong> “objective test” <strong>in</strong> the trial.<br />
Much space is devoted to the Borg ‐ HR (heart rate) relationship, apparently without understand<strong>in</strong>g that it<br />
may have little application for people with <strong>ME</strong>/CFS. The Borg Scale has been shown to be higher <strong>in</strong> people<br />
with <strong>ME</strong>/CFS than <strong>in</strong> controls.<br />
The Borg Scale is used by sports coaches and by personal tra<strong>in</strong>ers to measure athletes’ and body‐builders’<br />
levels of <strong>in</strong>tensity <strong>in</strong> tra<strong>in</strong><strong>in</strong>g; it measures perceived exertion. In medic<strong>in</strong>e, it is used to document the<br />
patient’s exertion dur<strong>in</strong>g a test and <strong>in</strong>cludes a measure of breathlessness <strong>in</strong> relation to heart rate (HR).<br />
Still <strong>in</strong> Phase 1, therapists are taught that: “The ma<strong>in</strong> purpose of engag<strong>in</strong>g the participant <strong>in</strong> the model is to allow<br />
the participant to understand the multifactorial <strong>in</strong>fluences exercise can have on their health and CFS/<strong>ME</strong> recovery” .<br />
It is not ethical <strong>in</strong> a trial to tell the participants <strong>in</strong> one arm of the trial that the “treatment” they are receiv<strong>in</strong>g<br />
can lead to recovery. The participants have a right to know that people who have undergone GET have<br />
been made severely and permanently worse by it (see Section 1 above).<br />
The therapist is next taught about “boom and bust” patterns of behaviour which the authors assert occur <strong>in</strong><br />
participants: “over activity may lead to an <strong>in</strong>crease <strong>in</strong> rest and a decrease <strong>in</strong> fitness and function if prolonged”.<br />
Unfortunately, the authors’ explanation is illogical. Assum<strong>in</strong>g (i) that the participant is <strong>in</strong> a “boom and bust”<br />
pattern of activity and (ii) that the decondition<strong>in</strong>g hypothesis is correct, then after every “bust”, the person<br />
would deteriorate and not return to their prior level of fitness, ie. for the assumptions to be correct, one<br />
would expect to observe progressive deterioration <strong>in</strong> all <strong>ME</strong>/CFS patients, but this is not the case, hence one<br />
of these assumptions is <strong>in</strong>correct.<br />
The therapists are <strong>in</strong>formed: “Many people with CFS/<strong>ME</strong> f<strong>in</strong>d…there is a significant post‐exertional response” (all<br />
people with <strong>ME</strong>/CFS experience a post‐exertional response: if they do not exhibit this card<strong>in</strong>al feature of<br />
<strong>ME</strong>/CFS, then they do not have <strong>ME</strong>/CFS and should not be <strong>in</strong> the PACE Trial).
