Study Details

Study Description

Brief Summary

Improving trunk muscle strength and endurance is one of the many goals to be achieved in rehabilitation protocols for a variety of health conditions. Cerebral electrical stimulations techniques, such as transcranial direct current stimulation (tDCS) can modulate motor brain areas involved in motor functions. However, their effects on trunk function are lacking.

This study aims to investigate the effects of transcranial direct current stimulation (tDCS) on trunk muscle strength and endurance in healthy subjects.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Active tDCS

Anodal tDCS over trunk motor cortex representation. Intensity: 2mA Time: 20 minutes

Device: Transcranial direct current stimulation (tDCS)
The noninvasive and nonpharmacological weak electrical current applied to the scalp to modulate cortical excitability.
Sham Comparator: Sham tDCS

Anodal tDCS over trunk motor cortex representation. Itensity: 2mA Time: 20 minutes (30s ON)

Device: Transcranial direct current stimulation (tDCS)
The noninvasive and nonpharmacological weak electrical current applied to the scalp to modulate cortical excitability.

Outcome Measures

Primary Outcome Measures

  1. Isometric trunk extension [Pre and Post-test (immediately after tDCS)]

    Maximal isometric voluntary contraction (Kgf)

  2. Trunk muscle endurance [Pre and Post-test (immediately after tDCS)]

Secondary Outcome Measures

  1. Isometric trunk extension [15 minutes post-stimulation]

    Maximal isometric voluntary contraction (Kgf)

  2. Isometric trunk extension [30 minutes post-stimulation]

    Maximal isometric voluntary contraction (Kgf)

  3. Trunk muscle endurance [15 minutes post-stimulation]

    Time to task failure (TTF) on the Sorensen test

  4. Trunk muscle endurance [30 minutes post-stimulation]

    Time to task failure (TTF) on the Sorensen test
