Effectiveness of Hydrogalvanic Bath on Improving Pain, Disability, and Quality of Life in Individuals with Chronic Nonspecific Neck Pain: A Randomized Controlled Trial

Abstract EN

Background.

Neck pain is one of the world’s leading factors in years lived with disability.

Ambiguity in the effect of electrotherapy modalities for the treatment of chronic nonspecific neck pains (CNSNP) needs to be examined further.

This study sought to elucidate the effectiveness of hydrogalvanic bath on improving pain, disability, and quality of life among individuals with CNSNP.

Methods.

Thirty-four individuals with a diagnosis of CNSNP were selected through convenient sampling and randomly divided into two groups by block randomization.

The control group treatment underwent low Transcutaneous Electrical Nerve Stimulation (TENS) and exercise, and the experimental group was subjected to hydrogalvanic bath therapy (HGBT) and exercise.

Individuals were evaluated for pain using a visual analog scale (VAS), disability with the Neck Disability Index (NDI), and quality of life with Short Form-36 (SF-36).

These measures were applied at baseline and after 12 weeks of treatment.

Results.

The pretreatment and posttreatment results for VAS, NDI, and SF-36 were compared for both control and experimental groups.

We found that all the three variables showed significant differences between the two time points with p<0.05 in both the groups but the experimental group improvements were more significant than the control group with p<0.05.

Conclusion.

Twelve weeks of low TENS or HGBT along with exercises can decrease pain and neck disability and increase the quality of life in individuals with CNSNP.

However, HGBT along with exercise has superior effects relative to low TENS along with exercise.

This randomized controlled trial was registered in the International Standard Randomized Controlled Trials Number-ISRCTN29695190 and registered on 05/02/2020.

This study is a retrospective registration.
