Study summary

The goal of this clinical trial is to assess the effects of eccentric arm-crank (KREHA) training compared to standard clinical routine strength (STAN) training in individuals undergoing primary spinal cord injury (SCI) rehabilitation.

The main questions this trail aims to answer are:

  • what are the effects of the training on upper body strength, aerobic performance, muscle volume, functional independence, and health-related quality of life?
  • is the KREHA training feasible to implement into the rehabilitation routine?

Participants will:

  • perform either 20 KREHA sessions or 20 STAN sessions within 12 weeks
  • perform a test battery to collect data on training effects before (pretest) and after (posttest) the study intervention

Exclusion criteria

Exclusion Criteria:

  • inflammatory or neurodegenerative diseases (including multiple sclerosis or Guillain-Barré syndrome).
  • comorbidities or other health issues that may interfere with study participation, inability or to undergo the investigated intervention.
  • MRI contraindications (magnetic metal parts or electronic implants such as pacemakers in the body).
  • pregnancy (anamnestic).
Terms in these criteria, in plain language(2)

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.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Study arms

  • Experimental
    Eccentric arm-crank (KREHA) training

    The eccentric training intervention consists of 20 training sessions performed on a symmetric arm-crank (Krafttraining mittels exzentrischer Handkurbel, KREHA) device. The training sessions have a duration of approximately 30 min and will be completed within twelve weeks, with a maximum of three sessions per week.

    Procedure: Eccentric (KREHA) training

  • Active comparator
    Standard clinical routine strength (STAN) training

    The standard strength training intervention consists of a total of 20 training sessions at the gym of the study center, performed following clinical routine procedures. The training sessions have a duration of approximately 60 min and will be completed within twelve weeks, with around three sessions per week.

    Procedure: Standard clinical routine strength (STAN) training

Interventions

  • ProcedureEccentric (KREHA) training

    20 eccentric resistance training sessions will be performed on a symmetric arm-crank ergometer in a supine position.

  • ProcedureStandard clinical routine strength (STAN) training

    The regular strength training intervention consists of a total of 20 training sessions at the gym of the study center, performed following clinical routine procedures.

What researchers measure

Primary outcomes

  1. Upper body strength

    Change in upper body strength will be measured by a one-repetition maximum (1RM) bench press (in kg). The maximum amount of weight that can be pushed upwards for one repetition, while lying in a supine position on a weight training bench.

    Time frame: < 1 week pre and 12 weeks post intervention start.

Secondary outcomes

  1. Upper body strength

    Change in upper body strength measured by a 1RM bench pull (in kg). The maximum amount of weight that can be pulled upwards for one repetition, while lying in a prone position on a weight training bench.

    Time frame: < 1 week pre and 12 weeks post intervention start.

  2. Handgrip strength

    Change in maximum strength of three handgrip measurements (in kg) of both hands using a Jamar Handgrip Dynamometer.

    Time frame: < 1 week pre and 12 weeks post intervention start.

  3. Aerobic performance

    Change in cardiopulmonary adaptations, measured by aerobic performance in an exercise test on a regular arm-crank ergometer. A ramp protocol starting at 20 Watt followed by 1 Watt / 6 sec increments to failure will be used. The following parameters will be evaluated during this aerobic endurance test: power at failure at the end of the test (in Watt), peak oxygen uptake during the test (in ml/kg/min), maximal heart rate (bpm)

    Time frame: < 1 week pre and 12 weeks post intervention start.

  4. Muscle volume

    Magnetic resonance imaging (MRI) of relevant upper body muscles of the dominant upper arm and shoulder will be used to measure change in muscle volume.

    Time frame: < 1 week pre and 12 weeks post intervention start.

  5. Arm circumference

    Change in arm circumference of the right and left lower and upper arm (in cm), will be used to estimate muscle volume.

    Time frame: < 1 week pre and 12 weeks post intervention start.

  6. Functioning during activities of daily living

    Change in functioning during activities of daily living will be assessed by the Spinal Cord Independence Measure (SCIM) as extracted from clinical records. The SCIM total score ranges from 0-100, with higher scores indicating higher levels of functional independence.

    Time frame: < 1 week pre and 12 weeks post intervention start.

  7. Health-related quality of life

    Change in health-related quality of life will be assessed using the Short Form Health Survey (SF-12). Weighted physical and mental component scores range from 0-100, with higher scores indicating better physical or mental health.

    Time frame: < 1 week pre and 12 weeks post intervention start.

Other outcomes

  1. Feasibility of the KREHA training (total number of training sessions)

    Successful implementation of the KREHA training in the clinical routine, by assessing whether the 20 KREHA sessions are completed within 12 weeks.

    Time frame: Throughout the intervention phase, week 0-12

  2. Feasibility of the KREHA training progression (number of sessions adapted)

    Feasibility of the KREHA training progression, by assessing how many training sessions needed to be adapted.

    Time frame: Throughout the intervention phase, week 0-12

  3. Feasibility of the KREHA training progression (power adaptation)

    Feasibility of the KREHA training progression, by assessing how much the target power (in Watts) of a training session needed to be adapted compared to the initially planned progression.

    Time frame: Throughout the intervention phase, week 0-12

Start is estimated for Dec 2026; primary completion for Dec 2028, 24 months later.

Of 790 non-industry interventional studies with no phase under Spinal Cord Injuries, half reached primary completion within 37 months of starting (the median), counting those still running; a quarter within 18 and three quarters within 65. This study's planned 24 months is below that.

Counting every sponsor, half of 839 studies reached it within 36 months; a quarter within 17 and three quarters within 64.

Since we started tracking on Sep 25, 2026, the dates moved once, on Sep 28, 2026: start Jul 2026 → Dec 2026, primary completion Jul 2028 → Dec 2028 and completion Jul 2028 → Dec 2028.

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.
