Study: NCT04317937

Intervention type: OTHER
Group type: EXPERIMENTAL
Intervention: Jaw opening-closing movements
Description: Jaw opening-closing movements Patient seated on a normal standard comfortable chair with proper back support and feet placed on the floor with no head support.~Active jaw movements The patient will then perform maximal Jaw opening-closing movements at a pace convenient for his/her for 15 times. Three sets with two minutes rest in between will be ensured.~Active neck exercises While performing the above movements of jaws, the patient will actively perform active neck exercise (head-neck movements in sagittal plane- Extension- Flexion).~Head-Neck extension on jaw opening (Mandible moves vertically downward); and then from Head-Neck extension to natural flexion movement on jaw closing (Mandible moves vertically upward).

Intervention type: OTHER
Group type: ACTIVE_COMPARATOR
Intervention: Specific Active exercises
Description: Active neck exercises:~Patient seated on a normal standard comfortable chair with proper back support and feet placed on the floor with no head support.~Note: For Active neck exercise (flexion and extension movements of neck), firstly the patient will perform maximal Jaw opening-closing movements at a pace convenient for his/her for 5 times in order to observe (eyeball observation) the neck extension and flexion as reference point for each individual.~Using this reference points, the patient will ask perform below mentioned active neck exercise.~Active neck exercises: The patient will then perform active neck exercise (flexion and extension of neck) at a pace convenient for his/her for 15 times. Three sets with two minutes rest in between will be ensured.~Active jaw movement: While performing the above movements of neck, the patient will not perform any jaws movements.

Group type: ACTIVE_COMPARATOR
Intervention: Exercise Therapy
Description: Isometric strengthening exercises For flexion the starting position will be upright head and neck. The patient will be asked to hold this position.~For extension the starting position will be upright head and neck. The patient will be asked to hold this position.~For rotation the starting position will be upright head and neck. The patient will be asked to hold this position.~• In all above movements ( flexion, extension \& rotation) following method will be followed: Manual resistance will then be applied by the investigator by placing the hand on the patient's forehead, posterior part of the head and lateral part of the head with 6 second hold. 15 repetitions of this exercise will be performed. Three sets with one minute rest in between will be ensured.
