About this study
Official title: Investigation of the Influence of the Body Composition of Neurological (Early) Rehabilitants as Well as Their Change in the Course of Rehabilitation and the Effect on Rehabilitation Success - a Pilot Study
An optimal nutritional supply is associated with better outcome and recovery. For investigating the influence of the nutritional status and body composition on the course of rehabilitation, bioelectrical impedance analyzes (BIA) should be carried out on neurological (early) rehabilitants during the rehabilitation process.
Possible disturbances, suitable outcome valuesfor evaluation of the rehabilitation success (depending on the rehabilitation phase) as well as the required frequency of the BIA measurements in rehabilitation should be estimated with the help of this pilot study.
Read the detailed description
An optimal coverage of the required calorie requirement is a basic prerequisite for a speedy recovery. One study reports that almost every fourth patient is malnourished in German hospitals. Malnutrition is in turn associated with more complications, higher mortality and longer length of stay. The current DGEM (Deutsche Gesellschaft für Ernährungsmedizin) guideline "Clinical nutrition in intensive care" recommends a calorie intake of 24 kcal per kg body weight during the acute phase of the disease (days 1 to 7) and an increase of calorie intake to 36 kcal per kg body weight in the convalescence and rehabilitation phase.
In a recent study evaluating the weight profile of neurological, enteric-coated early rehabilitants in rehabilitation, 60.6% of patients had weight loss during rehabilitation. Men were also more likely to lose weight than women. In addition, the caloric care of "underweight patients" had a decisive influence on the neurological outcome (as measured by the early rehab barthel-index(FRBI)). For example, underweight patients who were under-served showed significantly lower improvements in FRBI than underweight patients who were over-served.
In another study, the weight of patients remained stable through the use of a nutritional assessment tool (EAT). Also the gender difference was not confirmed in the group with the EAT. The weight change in the rehabilitation course correlated significantly with the difference between the calculated and the average calories received per day. However, an effect of EAT on the frequency of complications or the neurological outcome could not be demonstrated in this study.
However, as body weight may be affected by water balance (edema) and gastrointestinal complications such as constipation, vomiting and diarrhea, consideration of body weight to check diet / nutrition status alone is insufficient. Qualitative statements such as an increase / decrease in muscle mass can not be made on the basis of the weight data. Therefore, in the planned pilot study body composition will be documented by means of bioelectric impedance analysis (BIA) in neurological (early) rehabilitants during rehabilitation. At the same time, various outcome parameters are to be recorded.
The aim of this pilot study is to identify the number and frequency of BIA measurements required to assess the status of care. On the basis of this data, a study is then to be designed to investigate the success of rehabilitation as a function of nutritional status and muscle mass.

The primary outcome is the main question the study is designed to answer.
Functional Status
The Early Rehabilitation Barthel Index were determined upon admission and at the end of rehabilitation.
Measured: 3 minutes

An ICF-Assessment of 20 items is used for determination of disabilities of activities and body functions. The severity of each item is scored from zero ("no impairment") to four ("complete impairment") upon admission and at the end of rehabilitation.
Measured: 3 minutes
Muscle Strenght
The hand force is measured with a hand force dyometer three times on each hand upon admission and at the end of rehabilitation.
Measured: 3 minutes
Mobility
The mobility is assed by the Rivermead Mobility Index.
Measured: 4 minutes
Lenght Of Stay
duration of neurological rehabilitation (in days)
Measured: < 1 minute
Mortality
Number of deaths
Measured: < 1 minute
Discharge Level
Status at discharge (discharged at home / long-term care facility, follow-up rehabilitation, death, transfer to acute hospital)
Measured: < 1 minute
Secondary outcomes (3)
Bioelectrical Impedance
Bioelectrical Impedances for all body segments: right arm, left arm, right leg, left leg, trunk, right body side and left body side.
Measured: 15 minutes
Nutritional Risk Screening (NRS 2002)
Malnutrition upon admission and at discharge is assed by the Nutritional Risk Screening (NRS 2002).
Measured: 5 minutes
Mini Nutritional Assessment (MNA)
Malnutrition upon admission and at discharge is assed by the Mini Nutritional Assessment (MNA).

Questions about this trial
What is this clinical trial studying?
An observational study of Neurological Rehabilitation, run by BDH-Klinik Hessisch Oldendorf at 1 site in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 1 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Functional Status (time frame: 3 minutes). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04204655, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Oct 2026.
