Effectiveness of music therapy and conventional program on pain, negative pain thoughts, and brain functioning in non specific chronic neck pain: a randomized controlled trial

INTERVENTION: Intervention1: Theta binaural beat therapy with excercise therapy: theta binaural beat therapy (TBBT) The TBB was created using a combination of 300 Hz and 306 Hz were generated using the open‐source software application Gnaural (GNU General Public License, GNU Project) The treatment with TBB consisted of a 300‐Hz frequency applied to the left ear and a 306‐Hz frequency applied to the right ear at the same time by noise free stereotype headphones . As a result, the brain internally perceived a TBB at a frequency of 6 Hz. During the intervention, participants were lying comfortably in a quiet room and instructed to rela Xwith eyes closed while listening to binaural beats of 6Hz (theta frequency). the binaural beats were delivered for 20 minutes prior to conventional program per session, ensuring equal and safe sound intensity (60 70 dB) in both ears. Control Intervention1: exercise therapy with sham intervention: sham intervention (ie, a single tone at 300 Hz) for 20 minutes with conventional physiotherapy, which included 10 minutes of hot fomentation followed by cervical isometric strengthening to facilitate deep neck muscle contraction and scapular strengthening.[24] Additionally, gentle stretching of neck muscles including the upper trapezius, sternocleidomastoid, and levator scapulae was performed, each held for 10 seconds and repeated three times CONDITION: PRIMARY OUTCOME: 1.Pain‐ Visual analog scale (VAS). ; 2. Pain Catastrophizing‐ Pain Catastrophizing Scale. ; 3. Event Related Potentials‐ EEG (ERP P‐300)Timepoint: baseline ; after 4 weeks SECONDARY OUTCOME: norwick park neck pain questionnaireTimepoint: baseline ; after 4 weeks INCLUSION CRITERIA: 1.Chronic non‐specific neck pain for a duration of more than three months.[14] 2.Age: 18 to 40 years. 3.Both male and female. 4. Score of 3 to 8 on a visual analog scale. 5.Mild visual impairment that are correctable with glasses
