Effects of Cervical Spine Retraction Exercise With and Without Diaphragmatic Breathing in Forward Head Posture.

Participants will hold cervical retraction for 10 s up to 10 times. A break of 5 s will be provided per one movement and 30 s per one set. A total of three sets will be conducted. Therefore, the total exercise time will be \<10 mints.

The diaphragmatic exercise will be performed in a supine position with 40° trunk flexion while holding 2.5 kg on the abdomen in the first 5 sessions and then 5 kg in the second 5 sessions. Participants will perform 3 sets with 10 repetitions at a ratio of one second of inspiration to two seconds of expiration, three sets of 15 repetitions at a ratio of two seconds of inspiration to four seconds of expiration, and three sets of 20 repetitions at a ratio of three seconds of inspiration to six seconds of expiration. The rest between rests will be 60 s.

"Hot fomentation will be given by applying cervical hot pack over the area in prone lying position for 10 mints and Isometric neck strengthening exercises (10 repetitions, each 5-second hold, 1 set) (20). • Nerve Stimulation (TENS) on the painful regions around the neck for 15 minutes with a TENS device. TENS parameters will be 150 μs square pulses with a frequency of 80 Hz.~The intensity of the current will be adjusted to produce no contraction.~• Posture education to keep upright posture during sitting."
