Brief Summary

This study evaluates the effectiveness of Kendall exercises in correcting postural deviations, such as forward head posture, associated with cervical spondylosis. By targeting muscle imbalances and improving alignment through stretching and strengthening protocols, the research aims to reduce symptoms, enhance cervical spine function, and promote postural health. Participants will undergo a four-week exercise intervention with pre- and post-assessments to determine the outcomes.

Outcome Measures

Primary Outcomes (4)

• Numeric Pain Rating Scale (NPRS)

  The Numeric Pain Rating Scale is an eleven-point pain impression scale: the patient rates pain from 0 (no aggravation) to 10 (most exceedingly terrible possible pain). Mild 1-3, Moderate 4-6, Severe 7-10. It has good test-retest reliability (r=.79-.96) in individuals with chronic pain and musculoskeletal pathology.

  4 weeks

• Range Of Motion: Goniometer

  A goniometer is a tool used to measure joint angles and range of motion (ROM). The goniometer has high intra-rater and inter-rater reliability when used by trained professionals. Consistent measurement can be achieved with proper technique and positioning. It provides valid measurements of joint ROM when compared with other objective measures such as radiographic assessments.

  4 weeks

• craniovertebral angle (CVA)

  The Craniovertebral Angle is one of the most reliable methods and common angles for evaluating the Forward head posture. It is the angle between a line drawn from the tragus of the ear to the C7 vertebra and a line drawn horizontally. A reduced CVA indicates a forward head posture.

  4 weeks

• Neck Disability Index (NDI)

  The Neck Disability Index (NDI) is a widely used self-reported questionnaire that measures the patient's perceived disability due to neck pain. It consists of 10 items, each scoring from 0 to 5, covering various aspects such as pain intensity, personal care, lifting, reading, headaches, concentration, work, driving, sleeping, and recreation. Cronbach's alpha value for NDI was found to be .95 and this was statistically significant (p\<.01).
