Mechanical neck pain is very common and can cause significant pain, stiffness, difficulty moving the head, and problems with daily activities.\n\nFifty adult females aged 18 to 45 years with mechanical neck pain lasting more than 4 weeks will be randomly divided into two equal groups. Group M (25 participants) will receive upper cervical spine manual therapy using the Mulligan mobilization technique, which involves gentle joint movements to restore normal neck joint motion, combined with standard cervical exercises. Group B (25 participants) will receive the same Group M treatment plus biofeedback-guided deep cervical flexor training. This additional exercise uses a pressure sensor placed behind the neck to help the patient learn to activate the deep stabilizing muscles of the neck, which are often weakened in people with neck pain.\n\nBoth groups will attend 3 treatment sessions per week for 4 consecutive weeks (12 sessions total). Each session lasts approximately 45 minutes. Before each session, all participants receive suboccipital release, myofascial release, and stretching exercises as preparation.\n\nThe researchers will measure pain intensity, upper cervical flexion range of motion, the flexion-rotation test (which assesses upper neck rotation), the Neck Disability Index (which measures how neck pain affects daily activities), and pressure pain threshold (which measures sensitivity to pressure over neck muscles). All measurements are taken before treatment begins and after the 4-week intervention period.\n\nThe study aims to determine whether adding biofeedback-guided deep cervical flexor training to the Mulligan manual therapy approach produces greater improvements in pain, neck mobility, disability, and muscle sensitivity compared to the Mulligan approach alone.",[115,116,117],"Neck Pain","Cervical Spine Dysfunction","Forward Head Posture",[119,120,121,122,123],"Mechanical neck pain","Biofeedback","Deep cervical flexor","Mulligan concept","Cervical range of motion","2026-10-05",{"date":126,"type":127},"2026-10-08","ACTUAL",{"date":129,"type":127},"2026-10-06",{"date":131,"type":109},"2026-12-06",{"name":5,"class":6},1]
