  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Sahrmann exercise
Other: Sahrmann exercise
Sahrmann exercises which include Deep Neck Flexor Activation (Chin Tucks), Cervical Flexion with Scapular Stabilization, Shoulder Blade Retractions, Controlled Cervical Rotations, Scapular Depression with Resistance Bands, Neck Flexion Isometric, Cervical Side Bending with Resistance, Thoracic Extension Exercises. Each containing 5 repetitions, each held for 5-10 seconds, Total 3 sessions per week for 4 weeks.
Other: Standard Physical Therapy Treatment
Both groups were given Standard Physical Therapy treatment including hot pack (applying a moist heat pack to the neck for 7-10 minutes, relaxing muscles, and alleviating pain. Use a towel as a barrier to avoid burns.) and Soft Tissue Mobilization Protocol (involves applying targeted pressure to neck muscles, releasing tension and improving circulation. Additionally, postural education focused on maintaining an upright posture while using mobile devices. This involved holding the device close to eye level and using it while either standing or sitting. Repeat 2-3 times daily for 4 weeks.
Active Comparator: Kendall Exercise
Other: Standard Physical Therapy Treatment
Both groups were given Standard Physical Therapy treatment including hot pack (applying a moist heat pack to the neck for 7-10 minutes, relaxing muscles, and alleviating pain. Use a towel as a barrier to avoid burns.) and Soft Tissue Mobilization Protocol (involves applying targeted pressure to neck muscles, releasing tension and improving circulation. Additionally, postural education focused on maintaining an upright posture while using mobile devices. This involved holding the device close to eye level and using it while either standing or sitting. Repeat 2-3 times daily for 4 weeks.
Other: Kendall exercise
Kendall exercise includes Deep Neck Flexor Activation (supine chin tucks) for 2 to 8s, stretch cervical extensors, Scapular Retraction with resistance, Pectoralis major and minor stretch. Each posture was maintained for 30s and 6 sets of 12 repetitions were performed with 3 sessions per week on alternate days for 4 weeks.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Numeric Pain Rating Scale
Time Frame: From enrollment to the end of treatment at 4 weeks
The Numerical Pain Rating Scale (NPRS) is a subjective measure in which individuals rate their pain on an eleven-point numerical scale. The scale is composed of 0 (no pain at all) to 10 (worst imaginable pain).
From enrollment to the end of treatment at 4 weeks
Neck Disability Index
Time Frame: From enrollment to the end of treatment at 4 weeks
Neck pain disability index is used for the disability of the neck or the impact of neck pain on a person. This 10-item questionnaire is used to assess the patient overall quality of life as well as the personal ability to perform activities of daily living. It has various categories ranging from personal care, lifting, reading etc. it has a scoring range from zero disability. The greater the scored the higher the disability of neck.
From enrollment to the end of treatment at 4 weeks

Secondary Outcome Measures

ROM Cervical Spine (Extension)
Time Frame: From enrollment to the end of treatment at 4 weeks
