简要总结
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.
详细描述
This study investigates the impact of Kendall exercises on posture-related cervical spondylosis, a degenerative condition often linked to postural deviations like forward head posture (FHP). Prolonged poor posture, frequently exacerbated by activities such as excessive smartphone or computer use, leads to muscle imbalances, increased mechanical stress on the cervical spine, and degenerative changes in intervertebral discs and joints.
Kendall exercises are targeted therapeutic interventions designed to address muscle imbalances by strengthening weak muscles (e.g., deep cervical flexors) and stretching tight muscles (e.g., upper trapezius, pectoralis muscles). These exercises aim to restore proper alignment, reduce mechanical strain, and improve overall posture and cervical function.
Participants with posture-related cervical spondylosis will engage in a four-week exercise protocol involving specific Kendall exercises for cervical extensors, flexors, shoulder retraction, and chest muscles. Outcomes will be assessed using craniovertebral angle measurements, photographic analysis, and subjective pain/function scales. The study seeks to establish Kendall exercises as a non-invasive, effective intervention for managing cervical spondylosis by correcting postural deviations and mitigating associated symptoms

结局指标
主要结局
Numeric Pain Rating Scale (NPRS)
时间窗: 4 weeks
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.
Range Of Motion: Goniometer
时间窗: 4 weeks
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.
craniovertebral angle (CVA)
时间窗: 4 weeks
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.
Neck Disability Index (NDI)
时间窗: 4 weeks
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).
