Effects of back exercises versus transcutaneous electric nerve stimulation on relief of pain and disability in operating room nurses with chronic non-specific LBP: a randomized clinical trial.(2022)

PICO

Patient/Population

Operating room nurses with LBP (n=44)

Intervention

  • TENS

Comparison

  • Back exercises (including the strengthening and stretching exercise)

Outcomes

  • Pain

  • Disability

Translatability:   (3/3) Easy                                    

Comments:Pain and disability were improved in both groups following 18 intervention sessions. However, improvements in pain and disability were greater in the TENS group as compared to back exercises group. Therefore, our findings suggest that including a TENS component to rehabilitation program for operating room nurses with chronic non-specific LBP may be beneficial.”
Limitations: single-center trial study; small sample; no control group;  it was impossible for the study to be blind for the TENS  participants.

Appraisals:

Trustworthiness – The study contains no serious weaknesses. Based on this result you should conclude that the trustworthiness of the study is high (90%). This means there is a 10% chance that alternative explanations for the effect found are possible. The effect size was large and 95% CI was OK. (by CAT)

Local/Technic:

The electrodes of the device were placed in the lower back region. A frequency of 100 Hz, and a duration of 0.2 ms was used.

    Intervention – 2

    • Exercises

    Dose

    • exercises were repeated 10–12 times, as many sets of exercise as up to 15 min

    Periodicity

    • 3 sessions per week for 6 weeks.

    Local/Technic:

    1)Pelvic tilt 2) Single knee to chest 3) double knee to chest 4) hip flexor stretches 5) squats.
