What is it about?
The study discusses the effects of trans-spinal direct current stimulation (tsDCS) on postural sway during quiet standing in healthy young subjects. The study did not find any statistically significant effects of tsDCS on postural sway, despite previous studies showing motor performance improvements in tasks executed with the lower limb. The study proposed an alternative stimulation protocol that addresses the issue of blinding the subject to different stimulus conditions, including sham trials, and suggested future research could verify if tsDCS can induce changes in quantifiers of postural control in other groups of subjects such as the elderly, elderly with a history of falls, or individuals with specific neurological disorders.

Why is it important?
This work is important because it investigates the effects of transcutaneous spinal direct current stimulation (tsDCS) on postural control in healthy young individuals during quiet standing. TsDCS is a non-invasive spinal cord electrical stimulation technique that has shown promise in inducing neuromodulation of local and distal neural circuits of the central nervous system (CNS), and previous studies have reported improvements in motor performance with tsDCS in healthy young individuals. This study addresses a gap in the literature by investigating the potential effects of tsDCS on postural control, which is relevant for various populations, including individuals with neurological disorders or elderly individuals who are at an increased risk of falls. The study also proposes a novel initialization of electrical stimulation to improve subject blinding and provides insights into potential limitations and challenges in using tsDCS for postural control. The findings of this study can inform future research on the use of tsDCS for improving postural control and balance in clinical populations and contribute to the development of optimized stimulation protocols and methodologies for tsDCS studies.
