The short-term effects of TENS plus therapeutic ultrasound combinations in chronic neck pain

Abstract

Introduction: To investigate the effects of TENS plus therapeutic ultrasound combinations on symptom relief, physical functionality, perceived stress levels, daytime sleepiness and neck mobility in patients with chronic neck pain (CNP).

Methods: A total of 64 patients were divided into two groups as the TENS plus ultrasound group (n = 39) and the control CNP group (n = 25). The therapy comprised TENS and therapeutic ultrasound applications for 10 sessions. The control subjects were discouraged from using analgesics but were allowed to use paracetamol daily, if necessary. The Neck Disability Index (NDI), Epworth Sleepiness Scale (ESS), Perceived Stress Scale (PSS), visual analog scale (VAS) and tragus-wall/chin-manubrium distances were recorded at the baseline and after therapy.

Results: Significant improvements were detected in the TENS plus ultrasound group compared to the control CNP subjects in respect of VAS, PSS and NDI scores after the TENS plus therapeutic ultrasound therapies (all p < 0.05).

Discussion: The combination of therapeutic ultrasound plus TENS can be an effective modality for relieving pain/stress levels and improving functionality in the short-term of CNP.
