Background. Neck pain can affect cervical functions: reduce cervical range of
motion, muscle strength and endurance. Recently, increasing attention has been
paid to the assessment of proprioception in individuals with neck pain. It is belie-
ved that neck proprioception dysfunction can be linked with neck pain, reduced
cervical range-of-motion, muscles strength and endurance.
The aim of research was to assess neck dysfunction and proprioception relationship with neck muscle functions, cervical range of motion in individuals with
neck pain.
Methods. Thirty fve neck pain patients participated in this survey. Neck pain
intensity was evaluated using a visual analogue pain scale, neck position sense,
cervical active range of motion, cervical muscle strength using Lafayette handheld
dynamometer, cervical muscle strength endurance were also evaluated in this study. The statistical analyses were performed. The averages and standard deviations
were calculated. Averages were compared with the norm rates. Spearman’s and
Pearson’s correlations were used for relationship assessment.
Results. The neck position sense and cervical active range of motion statistically signifcantly differed from the norm. There was a difference between lateral
neck flexion to the right and to the left – 18° (p < 0.05). The left neck rotation
muscles were stronger than the right ones (p < 0.05). Neck extensors had greater
endurance than neck flexors for 94.69 seconds (p < 0.05). A statistically signifcant
inverse relationship was found between pain and muscle strength, endurance, and
cervical flexion range of motion (p < 0.05). The neck position sense did not correlate with pain. Neck extension position sense negatively correlated with neck muscle group strength endurance (p < 0.05).
Conclusions. Individuals with neck pain had neck position sense impairment,
muscle imbalance between neck flexors and extensors, and reduced all cervical
ranges of motion. With increasing neck pain, intensity muscle strength, muscle
endurance, cervical flexion range of motion decreased, but the neck position sense did not correlate with pain. Neck extension position sense was related with all neck muscle group strength endurance.
