Long COVID is a new phenomenon, in which individuals who experienced a SARS-CoV-2 infection still experience one or more symptoms, such as exercise intolerance, fatigue and/or muscle pains in addition to other COVID-related symptoms, weeks to months after initial infection. The aim of this pilot-study is to learn about which complaints patients continue to experience after their infection and how this affects their lives to a greater or lesser extent and whether a patient-tailored physical rehabilitation programme combined with individualised nutritional therapy leads to a faster recovery compared to a classic exercise program with the physiotherapist.
The rapid spread of SARS-CoV-2 virus has already led to more than 212 million confirmed cases. The acute phase of infection resulted in variable clinical presentations, from asymptomatic to severe illness requiring admission at an intensive care unit. As the COVID-19 pandemic evolves, long-term symptoms and functional problems related to the SARS-CoV-2 infection reached the surface. Approximately 5-10% of the infected people experience prolonged symptoms with predominant symptoms being overall reduced physical capacity, fatigue and muscle weakness. Exertional intolerance/post-exertional malaise is also frequently seen. A growing group of patients experience persisting symptoms after the initial infection and these can have significant impact on daily functioning and quality of life. These patients feel 'abandoned' by healthcare providers and receive limited or conflicting advice. Treatment modalities for patients with long COVID have up and till now been scarcely investigated because there is insufficient understanding of the underlying mechanisms. However, most patients seek care and the majority of them receive physiotherapy/rehabilitation in one form or another in the 3 to 6 months after onset. Unfortunately, this seems not to be enough, on the contrary, patients seem to experience even more difficulties. Nutrition-wise, after highly prevalent weight loss in the active phase of COVID-19, challenges remain to improve protein intake and gain muscle mass. This stresses the need for a multidisciplinary approach and social support. The aim of the current study is to investigate if a patient-tailored physical rehabilitation programme combined with nutritional optimisation with individualised therapy and counselling may lead to a faster improvement of functional performance compared to a standard physiotherapy programme in patients suffering from long-term effects (\> 12 weeks) of COVID-19.

This personalised multimodal treatment considers evidence- and practice-based elements (e.g., self-management, individual guidance \& follow-up, low-threshold activities, homebased functional training \& better follow-up guidance afterwards).

1-minute sit-to-stand (1-MSTS)
Testing of endurance and muscle strength of the lower extremities (standing up from a sitting position for as many repetitions as possible during 1 minute)
Time frame: Change from Baseline Repetitions Sit-To-Stand's in one minute at 12 weeks
Multi-dimensional Fatigue Inventor (MFI-20)
The MFI is a self-report instrument designed to measure fatigue and was initially developed in Dutch17 for patients with cancer. It covers the following dimensions: general fatigue, physical fatigue, reduced activity, reduced motivation and mental fatigue. It consists of 20 items divided over 5 dimensions (each 4 items) and is scored on a 5-point Likert scale. The higher the score the more severe the fatigue and by consequence the more impact fatigue has on daily functioning.
Time frame: Change from Baseline MFI-20 at 12 weeks, at 6 weeks intervention, at 12 weeks, and at 6 weeks post-intervention.
EuroQol five-dimensional (five-level version) (EQ-5D-5L)
Health-related Quality of Life will be measured by the EQ-5D-5L. This questionnaire comprises 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each has 5 levels from no problems tot extreme problems. Next it contains a self-rated health status on a vertical visual analogue scale where the endpoints are labelled the best health you can imagine' and 'the worst health you can imagine'. This test has proven valuable for assessing physical health-related QoL (25).
Time frame: Change from Baseline EQ-5D-5L at 12 weeks, at 6 weeks intervention, at 12 weeks, and at 6 weeks post-intervention.
Post-COVID-19 Functional Status (PCFS)
Functional status will be evaluated for changes using the PCFS, specifically developed for COVID patients by Klok and colleagues.
Time frame: Change from Baseline PCFS at 12 weeks, at 6 weeks intervention, at 12 weeks, and at 6 weeks post-intervention.
Hospital Anxiety and Depression Scale (HADS)
Mental status will be evaluated for differences using HADS.This test is a simple tool to assess both anxiety and depression, each with 7 questions.
Time frame: Change from Baseline HADS at 12 weeks, at 6 weeks intervention, at 12 weeks, and at 6 weeks post-intervention.
Work Productivity and Activity Impairment (WPAI)
Work capability will also be assessed using the Work Productivity and Activity Impairment. With 6 questions it asks about the decline in productivity and activity in the past 7 days. There are 3 versions available but all evaluate on absence, presence, loss of productivity and decline of activities during work. The WPAI is considered the best validated questionnaire for determining health-related work productivity and has been validated in various chronic inflammatory diseases.
Time frame: Change from Baseline WPAI at 12 weeks, at 6 weeks intervention, at 12 weeks, and at 6 weeks post-intervention.
