Clinical Trial Summary
Background: Cervicogenic dysphagia is a swallowing difficulty caused by cervical problems
that negatively impact pulmonary health, and quality of life and may increase the risk of
mortality.
Study design: Randomized Controlled Study Purpose: The purpose was to explore the effect of a
structured exercise training program composed of cervical stretching, strengthening and
stabilizing exercises on the swallowing function, craniovertebral angle, and pulmonary
function in patient with cervicogenic dysphagia.
Methods: 32 patients (age 35-50 years) with cervicogenic dysphagia were randomly allocated
into study group (n=17) and control group (n=15). The craniovertebral angle (CVA), the
swallowing function (using the swallow-difficulty questionnaire "SDQ") and the pulmonary
function (including the forced vital capacity "FVC" and forced expiratory volume in one
second "FEV1") were evaluated pre-study and post-study. All participants received three
sessions/week for 8-weeks. The study group received the structured exercise program, in
addition to the swallow resistance exercise (SRE), while the control group received the
swallow resistance exercise only.
Description:
Dysphagia is a common complaint in patients with cervical problems, and it is usually
transient and responds favorably to rehabilitation programs. Cervicogenic dysphagia is
difficulty in swallowing due to cervical spine pathology. Considering the close proximity of
the cervical spine to the oropharynx and esophagus; the existence of any cervical pathology
can adversely impact the pharynx and esophagus dimensions, through direct compression on the
esophagus resulting in epiglottic tilt, cricopharyngeal spasm, and disturbed laryngeal inlet
closure pattern, ending in disturbing the normal swallowing that can be evaluated by the
swallowing disturbance questionnaire results in which the lower scores on the swallowing
difficulty questionnaire reflects better swallowing status than higher scores, furthermore;
with the cut-off value for 12.5 is a good predictor of the disturbed swallowing function.
Cervical malalignment is associated with an increased incidence of dysphagia. Cervical
kyphosis is associated with malfunctional pharyngeal structure and disturbed swallowing.
Additionally; cervical kyphosis is associated with deep cervical flexor muscles' weakness
that in turn can significantly disturb cervical stability during swallowing. The combined
effect of muscle weakness and poor cervical posture negatively impacts the laryngeal and
cricopharyngeal sphincteric action and ends in cervical kyphosis.
Disturbed swallowing can negatively impact respiratory function, causing rapid deterioration
in patients' ventilatory function and increasing the rate of pulmonary disorders'
exacerbations. Maintaining normal swallowing function is essential in preventing consequent
pulmonary complications.
Mal-aligned cervical spine predisposes to altered pulmonary functions that can be
successfully corrected with therapeutic exercises, and manual therapy approaches.
A proper dysphagia management program is important not only to restore the normal coordinated
swallowing-breathing pattern; but also, to eliminate the dysphagia-associated morbidity and
health-related economic burden. Since cervicogenic dysphagia results from cervical spine
pathologies or deformities, management of cervicogenic dysphagia should be focused on the
treatment of cervical disturbances.
Postural correction therapeutic approaches are essential components in the dysphagia
management program, but current evidence about their efficacy in dysphagia treatment is still
limited. Although it is difficult to achieve a complete cervicogenic dysphagia cure;
conservative therapies targeting postural realignment can alleviate the symptoms and treat
cervicogenic dysphagia.
Definitely, there is a confirmed correlation between cervical spine pathologies and
oropharyngeal dysphagia, further research is warranted to further explore the efficacy of the
different rehabilitative non-surgical approaches in the treatment of cervicogenic dysphagia.
The objective of this study was to explore the efficacy of the structured physical therapy
treatment program on pulmonary function, swallowing difficulty, and craniovertebral angle in
patient with cervicogenic dysphagia.
