The aim of this randomized-controlled study was to determine the effectiveness of neuromuscular electrical stimulation (NMES) applied simultaneously to exercise on pain, static endurance of cervical deep flexor muscles, fear of movement and disability in chronic neck pain. The participants were randomly assigned to one group which in only five clinical pilates exercises were performed (Group I) or the other group which NMES was applied on lower trapezius and serratus anterior muscles while the same exercises were performing (Group II).
The aim of randomized-controlled study was to determine the effectiveness of neuromuscular electrical stimulation (NMES) applied simultaneously to exercise on pain, static endurance of cervical deep flexor muscles, fear of movement and disability in chronic neck pain. This study, including adults with chronic neck pain aged between 18-65 years, was conducted in laboratory of xxx University from March 2021 to May 2021. The participants were randomly assigned to one group which in only five clinical pilates exercises were performed (Group I) or the other group which NMES was applied on lower trapezius and serratus anterior muscles while the same exercises were performing (Group II). Both groups received 20 minutes of treatment session two days a week for the 8 weeks. The pain intensity, range of motion (ROM), static endurance of cervical deep flexor muscles, fear of movement, and neck disability were assessed with Visual Analogue (VAS), universal goniometer, The Deep Neck Flexor (DNF) Endurance Test, Tampa Scale of Kinesiophobia (TSK) and Neck Disability Index (NDI), respectively. All the assessments were performed twice as before and end of the treatment.

the patients were performed following five exercises for 20 minutes of treatment session two days a week for the 8 weeks.: (1) the swan-dive vol. I, (2) the swan-dive vol II., (3) breast stroke preparation vol. I, (4) breast stroke preparation vol. II, and (5) swimming vol. II. All the exercises were repeated for the 10 times in a session. Before the exercises, patients were taught and instructed about the five key elements (lateral expansion, centralization, positioning the chest, the shoulder girdle, and the head) of clinical pilates that they should pay attention to while performing the exercises. In addition, verbal and tactile feedbacks were given to patients during all the treatment sessions to maintain the good posture and to perform exercises properly.
Two channels of four-channelled Compex SP Fit-3 (MediCompex SA in Geneva, Switzerland) was used to apply NMES (120 mA, 400 μs, 150 Hz) on lower trapezius and serratus anterior muscles for 20 minutes during exercise.

Neck disability
The Neck Disability Index consisted 10 questions investigating the pain intensity and difficulty in lifting, reading, concentration, working, sleeping and recreational activities. Each question is scoring from 0 to 5 and higher score means greater disability.
Time frame: baseline (first assessment)

Pain intensity
The neck pain intensity of the participants were assessed with VAS which is a widely used pain assessments in the musculoskeletal disorders. The participants were asked to rate their pain intensity with a mark on a 10 cm line, which starts with "0-no pain" and ends with "10-unbearable pain". The distance of the mark to the 0 point was measured with a ruler and the pain intensity was recorded as cm.

Range of Motion
Cervical ROM in all six directions (flexion-extension, lateral flexion, and rotation) were assessed with universal goniometer. Universal goniometer were shown to have good to excellent intra-rater and inter-rater reliability to assess ROM of cervical spine (10.1093/ptj/71.2.98). The measurement were performed as described in (https://doi.org/10.21315/mjms2021.28.2.9). The measurement of each six directions were repeated three times and means were recorded as degree.

Static endurance of cervical deep flexor muscles
Deep Neck Flexor ((longus capitis, longus colli, rectus capitis anterior and lateralis) Endurance Test was used to static endurance of cervical deep flexor muscles. The subjects began in a supine, hook-lying position, with the hands resting on the abdomen. Upon request, with the chin in maximally tucked position and maintained isometrically, the subject lifted the head and neck approximately 2.5 cm from resting position The duration of holding the head position properly was timed, and static endurance of the DNF was recorded as second.

Fear of the movement
Tampa Scale of Kinesiophobia is a Likert type questionnaire consisted of 17 questions scoring from "1-strongly disagree" to "4-strongly agree". Scoring of questions 4, 8, 12, and 16 are reversed. The higher score means greater fear of movement.
