Treatment and study plan

Sahrmann exercise

Other

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.

Kendall exercise

Other

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.

standard physical therapy treatment

Other

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.

Primary outcomes

  1. 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).

  2. 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.

Secondary outcomes

  1. ROM Cervical Spine (Flexion)

    Time frame: From enrollment to the end of treatment at 4 weeks

    Changes in cervical spine flexion ROM at baseline and 4th week of intervention was measured using goniometer.

  2. ROM Cervical Spine (Extension)

    Time frame: From enrollment to the end of treatment at 4 weeks

    Changes in cervical spine extension ROM at baseline and 4th week of intervention was measured using goniometer.

  3. ROM Cervical Spine (Lateral Flexion) Left Side

    Time frame: From enrollment to the end of treatment at 4 weeks

    Changes in cervical spine Lateral flexion on left side ROM at baseline and 4th week of intervention was measured using goniometer.

  4. ROM Cervical Spine (lateral Flexion) Right Side

    Time frame: From enrollment to the end of treatment at 4 weeks

    Changes in cervical spine lateral flexion on right side ROM at baseline and 4th week of intervention was measured using goniometer.

  5. ROM Cervical Spine (Rotation) Left Side

    Time frame: From enrollment to the end of treatment at 4 weeks

    Changes in cervical spine rotation on left side ROM at baseline and 4th week of intervention was measured using goniometer.

  6. ROM Cervical Spine (Rotation) Right Side

    Time frame: From enrollment to the end of treatment at 4 weeks

    Changes in cervical spine rotation on right side ROM at baseline and 4th week of intervention was measured using goniometer.
