Clinical Trial Summary

The aim of this randomised multicentre clinical feasibility and pilot trial is to test if a sit-to-stand trial protocol is feasible regarding the increased intensity, trial recruitment, and completion of outcome data in patients with moderate to severe traumatic brain injury during the rehabilitation phase. For the trial to be feasible, all outcomes must be achieved.

The primary hypothesis is that it is feasible to progressively increase the number of repetitions of sit-to-stand exercises in patients with moderate to severe traumatic brain injury admitted to a rehabilitation department during the intervention period.

Furthermore, the investigators hypothesize that the increased number of repetitions will increase the participant's functional capabilities regarding sit-to-stand and walking, decrease resting heart rate, blood pressure, and metabolism, reduce inflammatory and brain injury biomarkers, and improve the cognitive performance.

Description:

This is a randomised multicentre clinical feasibility and pilot trial, where assessors and statisticians will be blinded. Forty-four participants with moderate to severe traumatic brain injury will be randomised to INSPIRE versus standard care as soon as they are able to understand and execute simple commands twice during one day. Participants in the INSPIRE group will undergo two weeks of intensive sit-to-stand exercise using an algorithm to increase the intensity daily. The trial uses predefined dose-limiting events to reduce training intensity in participants experiencing exercise-related adverse events that limit other daily activities and rehabilitation (e.g. muscle soreness and pain). Overall feasibility will be assessed by determining the inclusion rate, exercise completion rate, and completion of the Glasgow Outcome Scale - Extended. As exploratory clinical outcomes, the investigators will assess serious adverse events and adverse events not considered serious, physical function, cardiovascular and metabolic health, fatigue, and cognitive function.

Eligibility

Inclusion Criteria:

• Moderate to severe traumatic brain injury with Glasgow Coma Score <13 within the first 24 hours (ICD10, DS06)

• Admitted for rehabilitation at the Department of Brain and Spinal Cord Injury, Division of Brain Injury, Rigshospitalet, the Regional Hospital, Hammel Neurocentre or the Acquired Brain Injury Rehabilitation Centre, Alfred Hospital

• 18 years old or older

• Patients (or next of kin) should be able to understand written and spoken Danish or English to consent to participation in the trial validly

Exclusion Criteria:

• Amputation of lower extremity

• Spinal cord injury

• Total paralysis of both lower extremities

• Agitated or combative behaviour

• Diagnosed with a progressive neurological disorder (e.g. Alzheimer's, Parkinson's disease, multiple sclerosis) prior to traumatic brain injury, as it could potentially interfere with serum biomarker levels

Intervention

Other:
• INSPIRE intervention protocol
2-week training program with daily sit-to-stand exercises. Each working day the participant's goals will be adjusted, until exercising a minimum of 100 repetitions using an exercise progression table. When participants complete one level, they will progress to the next level the following day. Participants who do not reach the goals at level one will continue to strive to reach the 100 repetitions. The number of repetitions can be split and performed throughout the day. As the participants' capacity for doing the exercises increases, so will the number of repetitions within each bout of sit-to-stand. Participants are allowed to do the number of repetitions from a higher exercise level if they can and will continue by progressing from that level on the next day. The repetitions will be done from a height that makes it possible to accomplish the sit-to-stand movement. Therefore, the height of the sitting surface will be adjusted according to the participant's abilities.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Dose-limiting events	Examples of this could be fatigue or muscle pain that limits the participant in other activities of daily living and thereby reduces their amount of other rehabilitation services during the day	during the intervention, 72-hours after end of intervention
Other	Glasgow Outcome Scale - Extended	The scale is a global scale evaluating the independent function after traumatic brain injury.	at discharge, 6 months, 1 year
Other	Number of sit-to-stand exercises in each group during the intervention period (continuous outcome)	The total number of sit-to-stands in each group will be measured using an activity monitor placed on the participant's sternum and hip (Sens motion®, Copenhagen, Denmark)	during the intervention
Other	Number of sit-to-stand exercises during the 30-second chair stand test (continuous outcome)	The test is administered using a stopwatch and a chair. The participant is instructed to do sit-to-stand movements for 30 seconds. Time begins when the participant initiates the movement.	Baseline, 1 day after the intervention
Other	Walkers and non-walker (dichotomous outcome)	Walkers are defined by the ability to walk at any pace, with any walking aid, over minimum 50 meters independently (i.e. independent from physical assistance).	Baseline, 1 day after the intervention
Other	10-meter walk test (continuous outcome)	The walkers in each group will undergo a 10-meter walk test to assess walking speed	Baseline, 1 day after the intervention
Other	6-minute walking test (continuous outcome)	The walkers in each group will undergo a 6-minute walking test to assess and endurance	Baseline, 1 day after the intervention
Other	Resting blood pressure	Resting blood pressure will be measured on both arms for 5 minutes continuously before the first training session (8 am) using photoplethysmography to measure beat-to-beat blood pressure non-invasively.	Baseline, 1 day after the intervention
Other	Resting heart rate	An ordinary electrocardiogram available at the respective departments will be used to measure resting heart rate.	Baseline, 1 day after the intervention
Other	Blood samples	The blood samples will be analysed for high-sensitivity C-reactive protein, neutrophil-to-lymphocyte ratio, HbA1c, blood glucose, c-peptide insulin, blood lipids, inflammatory biomarkers, neuronal cell injury biomarkers, astroglia cell injury biomarkers, and axonal injury biomarkers. Finally, biomarkers associated with subacute/chronic traumatic brain injury phase will be analysed.	Baseline, 1 day after the intervention
Other	The Montreal Cognitive Assessment (MoCA)	The MoCA is a short cognitive questionnaire designed to test for mild cognitive impairments.	Baseline, 1 day after the intervention, 6 months, 1 year
