physiotherapy after COVID-19

 physiotherapy after COVID-19

 Here you will find practical information for treating patients with Corona/COVID-19 and complaints and consequences of COVID-19, such as recommendations for you as a physiotherapist, but also patient instructions and exercises on paper. We make a distinction between information about the hospital phase and the phase after discharge from the hospitals. 

General points of attention for infection risk and safety for the physiotherapist and patient Currently, it remains unknown how long patients can be infectious to others after symptoms of the active COVID-19 infection have subsided. There are indications that infectiousness can persist while being free of symptoms. Not only the patient, but also the physiotherapist can spread the virus, either directly, even when the physiotherapist is free of symptoms, or indirectly, when the physiotherapist has visited a patient with COVID-19.

1. Triage Given the current uncertainty regarding COVID-19 contagiousness and the importance of safety of the physiotherapist, patient and their environments, triaging of patients is important. We recommend to triage patients according to the national guidelines in health care for people with COVID-19. 

                    The principles of ‘social distancing’ (1.5 meters distance or e-health) should be considered and adhered to as much as possible for physiotherapy sessions 

                 If the patient has been tested positive for COVID-19 and/or has symptoms consistent with COVID-19 symptoms in the 14 days prior to triage, the physiotherapist should use personal protective equipment (surgical face mask (type IIR), glasses or face shield and disposable gloves) It is essential that the physiotherapist is familiar with their national guidelines on safety, infection control and transmission prevention and recommended organization of physiotherapy services. These may indicate the need for specific infection risk assessment, physical distancing and personal protective equipment.

2. Limitations in functioning and indication for physiotherapy

 Patients who have been severely or critically ill and/or have been hospitalized (for a prolonged time) may have (severe) limitations in physical, emotional, cognitive and/ or social functioning. 

Physiotherapy can play an important role in the rehabilitation of these patients and focuses mainly on limitations in physical functioning.

 It is important that the physiotherapist is aware of and identifi es other potential limitations that the patient may experience. In these cases, intra- or interdisciplinary collaboration may be required. Not all patients with COVID-19 will have an indication for physiotherapy. 

 Recommendations for physiotherapy in patients with COVID-19 patients with a request for guidance and presenting with limitations in physical functioning, e.g. activities of daily living, physical activity 5 or exercise capacity, are eligible for physiotherapy. Intra- and/or interdisciplinary collaboration is important for patients with a complex clinical situation and need for health care services. 

Patients with multiple and severe problems (physical, mental, cognitive and/or social) may benefit t from other health care providers during their rehabilitation. In these patients, physiotherapy as a sole health care service is not sufficient. 

 Functional limitations and indication for physiotherapy

 • Patients with a request for guidance and limitations in physical functioning have an indication for physiotherapy. 

• In complex cases, such as post-ICU patients with severe limitation and/or comorbidities, intraand interdisciplinary collaboration is required.

 3. Recommendations for physiotherapy 

The patient’s personal needs and request for guidance and their perceived limitations in physical functioning are always the main focus of physiotherapy. 

There is still little known about the course of recovery, physical capacity to load and physical limitations in patients who have had an active COVID19 infection. Patients planned to be discharged from hospital will not undergo an exercise test around the time of discharge, which normally provides an indication of lung and/or heart function. 

Therefore, there is lack of clinical information on the patient’s physical function and exercise capability. Hence, the physiotherapist has no specific clinical information to determine parameters for exercise prescription. Globally, the organization of healthcare and clinical follow-up may be considerably different. In some countries, such as the Netherlands, most patients who have been hospitalized receive a medical follow-up in the hospital after approximately six weeks of discharge. During the follow-up appointment physical functions (including lung and/or heart function) can be tested and physical activity and performance levels can be assessed.[24,25] Based on these test results, the physiotherapist can determine more adequately the patient’s exercise capacity and how to gradually increase their physical activity levels (using exercise prescription principles: frequency, intensity, time/duration and type). Patients who have experienced COVID-19 at home have not had and will not have tests in the hospital. With lack of information, their exercise capacity and tolerance levels remain more uncertain. In the following sections of this position statement, the clinical recommendations are divided into two main sections, based on time after illness and experienced physical abilities: the fi rst six weeks after hospital discharge or illness at home, and the period after these six weeks. 

Physiotherapy treatment

 • The patient’s personal needs and request for guidance and the perceived limitations in physical functioning are the main focus of physiotherapy. 

• There is still little known about the course of recovery, the physical capacity to load and physical limitations in patients who have had an active COVID-19 infection. Therefore, caution is needed when assessing and treating these patients. 

• Based on time after illness and experienced physical abilities the clinical recommendations are divided into two main sections: the first six weeks after hospital discharge or illness at home, and the period after these six weeks 6

 4. The first six weeks after hospital discharge / or illness from COVID-19 at home

 Patients who are discharged from the hospital often receive advice to gradually increase their activities of daily living, and are given functional physical exercises to perform at home. When there is an indication for physiotherapy at discharge, it is expected that patients will receive transfer information from the hospital. In some cases, patients will be contacted by telephone by (the physiotherapist of) the hospital after approximately two weeks. 

The aim of this consultation is to assess the progress of these patients’ daily functioning after discharge. When the patient still has (severe) limitations in their daily physical functioning there is an indication for physiotherapy. The hospital may refer the patient to a physiotherapist who can provide physiotherapy care to the patient in their home environment. However, the follow-up and organization of assessment may differ per hospital, region and country. 

If a patient has been admitted to a hospital, but there is no transfer, the physiotherapist is recommended to contact (the physiotherapy department of) the hospital for further information. Patients who were ill from COVID-19 at home will often have been and/or be in contact with their general practitioner (GP). 

This may also apply to patients who have been discharged from hospital and transferred to the GP for medical follow-up. The GP can consult with and inform a physiotherapist if deemed necessary. Patients, their relatives or other caregivers can also contact the physiotherapist directly. 

This group is expected to be small given the coordinating role of medical health care service providers, i.e. hospitals and GPs. In case of direct access to physiotherapy, it is strongly recommended to contact the patient’s GP prior to commencement of treatment. 

Interdisciplinary communication and collaboration are of great importance in delivery of adequate health care services. 

5. First consultation and indication for physiotherapy

 Within two weeks after hospital discharge or after symptoms of active COVID-19 infection have subsided the physiotherapist contacts the patient, in case a referral from the hospital or GP was received or in case of direct access.

 The aim of this first contact is to understand how the patient is feeling and what possible (physical) limitations the patient is experiencing - in all the domains of the World Health Organization’s International Classification of Functioning,

 Disability and Health (WHOICF) model. The physiotherapist should preferably use remote communication, such as telephone contact or video calling, as much as possible. Besides, recording existing and newly acquired comorbidities prior to or from Version 2.0 / 27 July 2020 13 KNGF position statement: 

Recommendations for physiotherapy in patients with COVID-19. COVID-19 including possibly affected organs, such as lungs and/or heart, is essential to be able to assess the patient’s current health status. When the patient is referred from a hospital or by a GP, such information is expected to be described in a transferal/referral note.

 Based on the obtained information from health care providers and the patient, the physiotherapist assesses the severity of limitations in the patient’s physical functioning using all the domains of the WHO-ICF model.

 Together with the patient’s specific needs and request for guidance, the physiotherapist decides whether there is an indication for physiotherapy.

 Patients who have been admitted to the ICU may have ICU-acquired weakness (ICUAW) and/or may experience Post Intensive Care Syndrome (PICS). 

These patients may experience severe physical deconditioning and malnutrition, with physical, mental and/or cognitive impairment. 

The capacity to exercise and perform (daily) activities is very low in these patients and the risk to overload is high. In these patients it is highly recommended to refer them (via the GP) to a rehabilitation center. When the patient experiences functional limitations and/or limitations in activities and/or participation in daily life and has a request for guidance, physiotherapy is indicated. 

7 First consultation

 • Within the fi rst two weeks after hospital discharge or after symptoms of active COVID-19 infection have subsided, contact the patient by telephone or video calling to assess the perceived limitations in physical functioning and determine whether there is an indication for physiotherapy.

 • Patients with a request for guidance and limitations in physical functioning have an indication for physiotherapy. 

• Be aware of existing or newly acquired comorbidities.

 6. Red and yellow flags

 Screening for red flags prior to further assessment and treatment in COVID-19 patients is very important. From some red flags, when present, the assessment or treatment must be temporarily discontinued. For other red flags, the physiotherapist should consult with the GP or other referring doctor.

 Red flags

 Discontinue the assessment/treatment and consult a doctor in case of:

 • Heart frequency in rest is 130 beats per minute

 • Respiratory rate of >40 per minute

 • Oxygen saturation in rest of ≤90% and/or during exercise/activity of <85%

 • Heart arrhythmia • Painful and swollen limbs (suspicion of deep vein thrombosis) 

• Acute dyspnea (due to suspicion of pulmonary embolism) 

• Recent myocardial ischemia

 • Excessive sweating, facial cues of feeling unwell (incl. color), anxiety 

Discontinue the assessment/treatment and repeat measurements at a later stage in case of:

 • Fever (core temperature >38.0° Celsius)

 • Exhaustion (Borg Scale score for fatigue ≥5 out of 10 while resting)

 • High blood pressure while resting (≥180/100 mmHg Yellow flags are also important to take into account during assessment and treatment sessions. 

Yellow flags are factors that may negatively influence recovery.

 The physiotherapist is advised to carefully screen for factors that may require the involvement of other health professionals, such as the GP, psychologist, social work, occupational therapist, dietician, or specialized physiotherapists (e.g. psychosomatic physiotherapist).

 See Appendix 1 for advice on yellow flags. 

 • Dysfunctional breathing

 • Delirium in recent medical history*

 • Fear of physical activity/exercise 

• Fear for shortness of breath 

• Sleeping problems

 • Post-traumatic stress syndrome**

 • External locus of control

(• Negative beliefs and/or concerns about symptoms * Almost 100% of patients with COVID-19 waking at ICU have delirium. ** Many patients with COVID-19 experience anxiety after hospital discharge.)

 7. Clinical outcome measures for the first six weeks

 It is important to identify factors that can influence recovery and/or can guide clinical decision making. The WHO-ICF can serve as a model to capture and organize several constructs from subjective and objective assessment. Clinical outcome measures are used to assess and evaluate the functioning of patients, guide clinical decision making and optimize treatment. The core set of clinical outcome measures for the first six weeks after hospital discharge or illness from COVID-19 at home consists of: 

• Patient Specific Functioning Scale (PSFS) to determine the perceived physical limitations in participation and activities of daily living.

 • Borg Scale CR10 for Shortness of Breath and Fatigue indicating shortness of breath and fatigue experienced by the patient. A maximum threshold score for exercise intensity of 4 out of 10 on the Borg Scale CR10 applies at this time after illness. 

• Oxygen saturation (SpO2 ) at rest, during and after physical activity and therapeutic exercise. If the physiotherapist has a pulse oximeter, it can be delivered to the patient’s home, when treatment is provided remotely.

 • Heart rate (HR) at rest, during and after physical activity and therapeutic exercise. In case of ehealth consultation, heart rate can be measured by instructing the patient on how to measure it himself, for example using the Version 2.0 / 27 July 2020 15 KNGF position statement: Recommendations for physiotherapy in patients with COVID-19 pulse oximeter or by instructing the patient how to measure it themselves with the heart rate indicated by the patient (‘counting strokes aloud’). The physiotherapist should be aware that outcomes can be influenced by medication.

 • Short Physical Performance Battery (SPPB) to measure balance, muscle strength and mobility. The SPPB consists of a balance test, walking speed over 4 meters and 5 times repeated standing up from a chair test. The physiotherapist must at all times ensure the safety of the patient if they are (seriously) weakened. In case of e-health consultation, the SPPB cannot be performed.

 • Grip Strength to estimate overall peripheral muscle strength. If possible and available, a hand-held dynamometer is used.

 • 6-Minute Walk Test (6MWT) to estimate the exercise capacity. In case of e-health consultation or the patient has (very) low exercise tolerance levels, the 6MWT should not be attempted. 

 • Short Nutritional Assessment Questionnaire (SNAQ65+) for early detection of malnutrition in patients who have been hospitalized. The physiotherapist uses the SNAQ65+ to identify a potential malnutrition status of the patient. A dietician should be consulted or referred to in case of signs of malnutrition. It is important that the physiotherapist and dietician have good communication and collaboration.

 In this position statement, the clinical outcome measures focus on physical functioning. Optionally, during the first six weeks, a pedometer/accelerometer can be used to determine and monitor daily physical activity levels. Also, one-repetition maximum (1RM) tests can be used to determine muscle strength of specific muscle groups and to determine initial intensities of exercises which improve muscle strength .

 Besides physiotherapy specific assessment and treatment, the physiotherapist plays an important role in identifying factors that may limit (the speed of) recovery, in particular in case the patient is not also monitored by the GP or hospital. Factors to be aware of include nutritional status, cognitive and emotional functioning and psychosocial functioning. A multidisciplinary approach may be necessary when such factors are present. The decision on specific clinical outcome measures also depends on collaboration with other healthcare disciplines.Use of different clinical outcomes for the same constructs by different healthcare professionals should be avoided to facilitate interdisciplinary communication and monitoring of the patient, and not burden the patient unnecessarily.

 10 Core set of clinical outcome measures ‘first six weeks’ 

• Use the Patient Specific Functioning Scale to identify perceived limitations in activities of daily living. 

• Use the Borg Scale CR10 to monitor shortness of breath and fatigue.

 • Before, during and after physical activity and exercises, monitor the patient’s oxygen saturation and heart rate.

 • Use the Short Physical Performance Battery (SPPB) to measure balance, muscle strength and mobility. 

• Use grip strength measurements (hand held dynamometer) to estimate overall peripheral muscle strength.

 • Use, when safe, 6-minutes walk test (6MWT) to estimate the exercise capacity.

 • Use the Short Nutritional Assessment Questionnaire (SNAQ65+) for early identification of potential malnutrition in patients who have been hospitalized. 

8. Advice and coaching

 It is important to provide information and educate the patient about the disease process, the expected course of recovery and physiotherapy treatment plan. If physical functioning of the patient is limited, the physiotherapist advises and coaches the patient to gradually increase physical functioning. For example, postural advice to promote breathing and to reduce tightness, mobilizing exercises aimed at activities of daily living, and exercise to improve strength of large muscle groups. In patients with (very) low exercise tolerance, for example those with PICS, resuming daily activities in the home environment should be gradual and well monitored. Activities of daily living and supporting therapeutic exercises should be performed at low to moderate intensity and be of limited duration at this stage. See further recommendations for exercise prescription below. 

                                   Advice and coaching 

• Provide information and educate the patient about the disease process, the expected course of recovery and physiotherapy treatment plan

 • Advise and coach the patient to gradually increase activities of daily living and physical activity, such as therapeutic exercises. Monitor the patient’s levels of daily functioning. 

•In patients with (very) low exercise tolerance, activities of daily living and additional exercise therapy should be performed at low to moderate intensity and be of short duration (see further recommendations for exercise prescription below).

 Exercise prescription Specific parameters for exercise prescription depend on activity levels of the patient prior to the COVID-19 infection, the patient’s needs and current physical abilities of the patient. In the first six weeks, the emphasis is on returning to activities of daily living. A maximum score of 4 out of 10 on the Borg Scale CR10 for Shortness of Breath and Fatigue is recommended. Reasons for this recommendation are:

    • COVID-19 can severely impact lung function (including oxygen desaturation during exercise due to virus-induced and/or pre-existing lung disease). 

  • COVID-19 can severely affect cardiac function (including virus-induced myocarditis, arrhythmia and/or pre-existing cardiac disease).
