Correlation Between Endurance and Proprioception Function in Cervical Radiculopathy

Обзор

In cervical radiculopathy, reduced endurance of the deep cervical flexor muscles is associated with impaired cervical proprioception. This relationship reflects altered sensorimotor control due to muscle dysfunction and neural compromise, emphasizing the need for deep flexor endurance training in rehabilitation.

Подробное описание

In patients with cervical radiculopathy, endurance of the deep cervical flexor muscles (longus capitis and longus colli) plays a crucial role in maintaining cervical segmental stability and accurate sensorimotor control. These muscles are rich in muscle spindles and provide continuous afferent input necessary for cervical proprioception, including joint position sense and movement accuracy. When deep cervical flexor endurance is reduced, there is increased reliance on superficial neck muscles, leading to altered motor patterns and diminished quality of proprioceptive feedback.

Cervical radiculopathy further disrupts proprioceptive function through nerve root compression, inflammation, and impaired neural conduction, which affect both sensory input and motor output. This neuromuscular dysfunction results in increased joint position errors, delayed muscle activation, and poor postural control. Consequently, a significant correlation is observed between decreased deep cervical flexor endurance and impaired cervical proprioception, suggesting that deficits in muscle endurance contribute directly to sensorimotor dysfunction. These findings support rehabilitation approaches that emphasize endurance training of the deep cervical flexors to restore proprioceptive accuracy and cervical motor control in patients with cervical radiculopathy.

Вмешательства

• Устройство cevical range of motion device
  Cervical proprioception was evaluated using the Cervical Range of Motion (CROM) device by assessing joint position sense (JPS). With the participant seated in an upright position, the CROM device was securely fitted to the head. The patient was instructed to actively move the head from a neutral starting position into a specific direction (flexion, extension, rotation, or lateral flexion), then return to the perceived neutral position with eyes closed. The difference between the starting neutra
