Study summary

The study investigates the efficacy of aerobic exercise on cognitive performance and brain plasticity in schizophrenia.

Read the detailed description

This multi-center, two-arm, parallel-group, randomized placebo-controlled add-on clinical trial investigates the efficacy of aerobic exercise on cognitive performance and brain plasticity in schizophrenia. The aim is the enhancement of recovery with the use of 26 weeks of continuos endurance training (aerobic exercise) with stationary bicycles or a balance and tone program consisting of exercises for flexibility, core strength, balance and relaxation. Followed by a follow-up period of 26 weeks.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • given by the subject; diagnosis of schizophrenic psychosis (295.10-30, 295.90); age 18 to 65 years, male or female; PANSS at baseline: total score ≤ 75, proper in female patients of ; treatment with one or two antipsychotics in a stable dose of at least two weeks, between 18 and 40.

Exclusion criteria

Exclusion Criteria:

  • Lack of accountability; positive urine drug-screening for illicit drugs at screening (except benzodiazepines); serious suicidal risk at screening visit; other relevant interferences of axis 1 according to diagnostic evaluation (MINI); other relevant neurological or other medical disorders; pregnancy or lactation.
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

DSM diagnostic criteria

The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

    Time frame: 12 months (at baseline, day 98, day 182 and day 365)

  15. improvement in quality of life

    Only at the beginning and end of the intervention, and after one year, is the World Health Organization's Quality of Life Questionnaire (WHOQOL-Bref) used to record quality of life (The WHOQOL Group, 1998).

    Time frame: 12 months (at baseline, day 182 and day 365)

  16. improvement in body mass index (BMI)

    Time frame: 12 months (at baseline, day 14, 68, 98, 140, 182, 196, 273 and day 365)

  17. change of connectivity analysis (MRI of the brain)

    At four time points, just prior to initiation of V1, V4, V6 after the end of the intervention and at V9 after the follow-up period of 6 months, structural and functional MRI (fMRI) examinations are performed on a 3 Tesla whole-body MR scanner in patients and healthy control subjects (Siemens) made. The findings are compared with data from healthy controls and non-diseased first-degree relatives of patients with schizophrenia who have been evaluated in other BMBF-funded studies ("MooDS", "IntegraMent"). In addition, cross-sectional comparisons (TAU + Exercise vs. TAU + BKGT) and progress measurements to characterize treatment effects are planned. The measurements are divided into 2 appointments to reduce the burden on patients and subjects by the measurement time.

    Time frame: 12 months (at baseline, day 98, day 182 and day 365)

  18. change of volumes of brain regions (MRI)

    First, structural measurements (T1 sequence, duration: approx. 5 minutes) and investigations of the fiber connections in the brain by means of diffusion-weighted imaging (DTI, duration: approx. 10 minutes) are carried out.

    Time frame: 12 months (at baseline, day 98, day 182 and day 365)

  19. change of brain function (MRI)

    By means of fMRI, the tasks resting activity, working memory, episodic memory, reward processing, social perspective takeover, emotion processing as well as ability to inhibit are to be investigated with already well pre-examined tasks. A function measurement is performed at rest without stimulation (rsMRT), which provides information on the functional networking of different brain regions at rest (duration: approx. 5 minutes). There are also three fMRI surveys that record brain activity during simple psychological tasks. - The ability to inhibit (prefrontal cortex, anterior cingulate gyrus) is examined by means of a so-called flanker task. This is to respond to a specific target stimulus, which is surrounded by either the same (congruent) or by distracting (incongruent) stimuli. - Duration: 11 minutes

    Time frame: 12 months (at baseline, day 98, day 182 and day 365)

  20. improvement of endurance capacity

    As part of the sports medical stress test, the determination of endurance performance in patients and control subjects takes place. For this examination, like in training, finder bike use and measurements of heart rate, lactate concentration and exertion sensation are performed. The ergometry is carried out as a Vita maxima examination, so it ends when the subjects can not or do not want to keep pedaling or when the termination criteria according to Steinacker \& Liu (2002) occur. From the examination, various submaximal and maximal parameters can be determined, have the validity for endurance performance and the training intensity can be determined. The examination is carried out under standardized and safe conditions and after a detailed medical history and physical examination to exclude contraindications. Activity meters are used to control the physical activity of study participants outside the study intervention.

    Time frame: 12 months (at baseline, day 98, day 182 and day 365)

  21. change of medication and attitude of the study participants to therapy (DAI)

    Also, the attitude of the study participants to therapy and medication is recorded. For this, the Drug Attitude Inventory (DAI) is used. Is takes place at the main measurement times (at baseline, day 98, day 182 and day 365).

    Time frame: 12 months (at baseline, day 98, day 182 and day 365)

  22. change of medication and attitude of the study participants to therapy (SES)

    The Service Engagement Scale (SES), which assesses accessibility, cooperation, help seeking and adherence, is used. It takes place at the main measurement times (at baseline, day 98, day 182 and day 365).

    Time frame: 12 months (at baseline, day 98, day 182 and day 365)

  23. improvement in metabolic parameters

    The laboratory diagnostic measures include a laboratory blood test, with evaluation of blood lipid levels, the C-reactive protein, glycohemoglobin (HBA1c). It takes place at the main measurement times (at baseline, day 98, day 182 and day 365).

    Time frame: 12 months (at baseline, day 98, day 182 and day 365)

  24. urine (testing pregnancy and drug abuse)

    Examination of the urine at baseline excludes pregnancy and drug abuse.

    Time frame: baseline

  25. gene expression

Ran from Jun 2016 to primary completion in Dec 2021, 66 months.

Of 753 non-industry interventional studies with no phase under Schizophrenia, half reached primary completion within 33 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 56. This study's 66 months is above that.

Counting every sponsor, half of 766 studies reached it within 32 months; a quarter within 16 and three quarters within 56.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 3, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
