Brief Summary

People with a spinal cord injury (SCI) often experience secondary medical complications. One of the methods that may help to prevent or deal with secondary complications in people with SCI is the Wim Hof Method (WHM). The WHM is based on three elements: 1) breathing exercises, 2) gradual cold exposure (cold showers, or cold water immersion), and 3) mindset. The primary objective of this randomized controlled trial is to assess the effects of WHM, involving breathing exercises, mindset (and cold exposure), on health-related quality of life in people with SCI. The secondary objectives are to assess the effects of WHM, involving breathing exercises, mindset (and cold exposure) in people with SCI on: inflammation markers, metabolic health, pulmonary function, body composition, sleep quality, spasticity, stress, and on chronic pain.

Outcome Measures

Primary Outcomes (1)

  • Change in mental health

    Mental Health Index - 5 (MHI-5), a subscale of the SF-36. The MHI-5 has a score of 0 to 100, where a score of 100 represents optimal mental health.

    Assessed before and after the 7-weeks WHM intervention

Secondary Outcomes (22)

  • Change in health-related quality of life

    Assessed before and after the 7-weeks WHM intervention

  • Change in mindful attention awareness

    Assessed before and after the 7-weeks WHM intervention

  • Change in hyperventilation

    Assessed before and after the 7-weeks WHM intervention

  • Change in pain and pain interference

    Assessed before and after the 7-weeks WHM intervention

  • Change in sleep quality

    Assessed before and after the 7-weeks WHM intervention

  • +17 more secondary outcomes

Study Arms (3)

Usual care group

NO INTERVENTION

The control group will not receive any intervention, they will receive usual care and only participate in the pre and post tests.

Wim Hof Method - breathing and mindset exercise

EXPERIMENTAL

The first intervention group will practice the breathing and mindset exercise.

Other: Wim Hof Methode

Wim Hof Method - breathing and mindset exercise and cold exposure

EXPERIMENTAL

The second intervention group will also practice the cold exposure (i.e, breathing, mindset and cold exposure)

Other: Wim Hof Methode

Interventions

The intervention groups will follow a 7-weeks intervention, with one practice session per week at the rehabilitation center led by Wim Hof or one of his instructors. Besides these joint weekly sessions, the intervention groups have to practice daily at home with the Wim Hof Method app.
