The purpose of the master's thesis was to evaluate the test-retest reliability of cervical spine functional tests in healthy older adults and to examine whether there are differences in active cervical range of motion and cervicocephalic kinaesthesia (position sense and movement
sense) between healthy adults and older adults. Two objectives were defined: to evaluate the test-retest reliability of (i) active cervical range of motion test, (ii) head-to-neutral relocation test and (iii) a method of active head and neck tracking – the Butterfly test in healthy older adults, and to examine whether there are differences in active cervical range of motion and
both tests of cervicocephalic kinaesthesia between healthy adults and older adults.
Sixteen adults (18-65 years) and sixteen older adults (≥ 65 years) participated in the study. Each participant completed two measurements on the same day with a 45-minute break in
between, during which functional tests of the cervical spine were performed in random order using an inertial measurement unit, which was placed on the participant's head.
We found moderate to good test-retest reliability of the active cervical range of motion test, poor to moderate test-retest reliability of the head-to-neutral relocation test, and good to excellent test-retest reliability of the Butterfly test in older adults. We also found that active
range of motion of the cervical spine was reduced in all directions of movement in healthy older adults compared to healthy adults. Regarding the position sense of the cervical spine, we found differences between the groups in flexion, rotation to the left and right, while no
differences were found in the extension of the head and neck. In examining differences in movement sense of the cervical spine between adults and older adults, we found differences in all variables of the Butterfly test, except for overshooting the target.
The master's thesis complements the existing research on cervical spine testing. The obtained results suggest that active range of motion and kinaesthetic functions of the cervical spine decline with age, therefore it would be reasonable to monitor these changes in older adults using comprehensive testing and reliable measurement procedures.
