In a previous post, we demonstrated that the symptoms and physiology of postexertional symptom exacerbation (PESE) are inconsistent with deconditioning. PESE worsens in response to exercise and demonstrates a variable clinical presentation. We will build a clinical rationale for energy system first aid as a place to start helping people with PESE.
Graded Exercise May Be Harmful to People With PESE
It is not surprising that patients with PESE frequently report worsening symptoms and function with exercise prescribed based on time and activity quotas,1 based on the physiological evidence. The United Kingdom’s Pacing, graded Activity, and Cognitive behaviour therapy, a randomized Evaluation (UK PACE) compared the clinical outcomes of specialist medical care, adaptive pacing, and graded exercise therapy (GET) in 641 people with idiopathic, disabling fatigue.9 In this study, GET was a quota-based progressive exercise program, where subjects incrementally increased exercise regardless of symptoms. PESE was not a specific recruitment criterion for this trial.8,9 The trial did not adhere to the published protocol, without appropriate justification. The raw data was independently reanalyzed according to the original protocol,10 Upon reanalysis, most symptomatic and functional outcome findings from the UK PACE trial did not reach thresholds for clinical relevance. Many ME/CFS experts contend the results of GET are marginal, probably not clinically relevant or beneficial.10
Despite the important concerns of the UK PACE trial, the trial continues to exert outsized influence on clinical guidelines.3 Some countries’ systems developed formal treatment pathways based on flawed results. Treatment pathways involving GET may have exposed an untold number of patients with ME/CFS worldwide to a GET program that, at best, is marginally effective, and at worst, may be harmful. Recent clinical guidelines for people with PESE, such as long COVID, no longer involve GET.6,7 These omissions reflect the ongoing re-evaluation of how clinical care should proceed for people with PESE, including people with long COVID. Implicit to this re-evaluation is a further reflection on the generally accepted idea that “movement is medicine” in a way that universally benefits clinical populations.
