Outcome Measures

Primary Outcomes (2)

  • Change from baseline in Numeric Rating Scale (NRS) of pain score at week 4 and 12

    NRS was used to evaluate the patients' general pain at rest and during activity (during activities of daily living). Patients were asked to rate their pain from 0 to 10, with 0 indicating no pain and 10 indicating the most severe pain

    At baseline, 4th week and 12th week

  • Change from baseline in Short-Form McGill Pain Questionnaire at week 4 and 12

    This questionnaire was used to assess the patients' pain. This questionnaire consisted of 15 descriptive words that evaluated the sensory (11) and affective (4) dimensions of pain. Pain intensity was evaluated as follows: 0=none, 1=mild, 2=moderate, and 3=severe. Three pain scores were obtained: sensory, affective, and total (both sensory and affective). The total present pain intensity index was evaluated using a 6-point Likert rating scale. (0 = no pain, 1 = mild, 2 = discomforting, 3 = distressing, 4 = horrible, and 5 = excruciating)

    At baseline, 4th week and 12th week

Secondary Outcomes (2)

  • Change from baseline in Fibromyalgia Impact Questionaire at week 4 and 12

    At baseline, 4th week and 12th week

  • Change from baseline in The 36-item Short-Form Health Survey at week 4 and 12

    At baseline, 4th week and 12th week

Study Arms (2)

PTNS+Duloxetine

EXPERIMENTAL

Posterior tibial nerve stimulation (PTNS), twice weekly, 3-4 days apart + Duloxetine 30 mg 1X1 p.o PTNS was applied using two 50 mm × 50 mm electrode pads per extremity. The live pad was placed superior to and medial to the medial malleolus. The ground pad was placed 5-10 cm proximal to the live pad. The PTNS was applied using biphasic square waves with a frequency of 10 Hz and pulse duration of 200 μs. The amplitude was adjusted to the level that produced painless paresthesia in each patient according to their tolerance. PTNS was applied for 30 minutes

Eligibility Criteria

Age18 Years - 65 Years
Sexfemale(Gender-based eligibility)
Gender Eligibility DetailsSince fibromyalgia is more common in women, female patients were included in the study.
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Female patients aged between 18 and 65 years, newly diagnosed according to the American Rheumatology Association 2016 revised FMS diagnostic criteria
  • Patients who come regularly to sessions for posterior tibial nerve stimulation.

You may not qualify if:

  • History of fracture/musculoskeletal surgery in the last 3 years
  • Inflammatory joint disease, or neurological disease/neurological deficit with examination
  • Receiving medical treatment for polyneuropathy
  • Contraindications to PNS (pacemaker, epilepsy, diminished skin sensation in the area to be applied).
