Insights
The Cervical Range of Motion goniometer is a valid tool for measuring cervical flexion and extension in healthy adults. This study confirms its accuracy against radiographic methods, supporting its clinical use.
Area of Science:
- Orthopedics
- Physical Therapy
- Radiology
Background:
- Lack of validated tools for cervical range of motion (CROM) measurement hinders objective clinical decision-making.
- Need for reliable instruments to justify patient status, treatment, and interventions.
- Budgetary constraints necessitate objective justification of therapeutic approaches.
Purpose of the Study:
- To assess the criterion validity of the Cervical Range of Motion (CROM) goniometer.
- To compare CROM goniometer measurements with radiographic methods in a healthy population.
Main Methods:
- A validity protocol was employed with 31 healthy participants (18-45 years old).
- CROM measurements were taken using the goniometer and compared with radiographic imaging.
- Data collection involved neutral, fully flexed, and fully extended cervical spine positions.
Main Results:
- High correlation was found between the CROM goniometer and radiographic measurements for cervical flexion (r = 0.97, P < 0.001) and extension (r = 0.98, P < 0.001).
- Pearson's r correlation test confirmed the criterion validity.
Conclusions:
- The CROM goniometer demonstrates validity for measuring cervical flexion and extension in healthy individuals.
- Further research is recommended to explore the instrument's validity for other cervical spine movements.
Study Design:
This study used a validity protocol.
Objective:
To estimate the criterion validity of the Cervical Range of Motion goniometer using a healthy population.
Summary Of Background Data:
The results of the 1994 study by Mayo et al show that there are no validated tools currently available for clinically measuring the cervical range of motion. Numerous decisions regarding patient status and treatment are based wholly or in part on joint motion measurements. Because of current budgetary restrictions, clinicians are being asked to justify their interventions objectively, and to do so, they will need validated tools.
Methods:
The population consisted of 31 healthy participants ranging in age from 18 to 45 years. None had experienced cervical problems in the previous 3 months or were pregnant. Data collection took place at the radiology department. After participants were positioned on a stool, the cervical range of motion goniometer frame was set on their head by the physiotherapist. With the participant in this neutral position, the physiotherapist took the first Cervical Range of Motion measurement. The radiograph technologist obtained the radiograph immediately afterward. This procedure was repeated with the participant in fully flexed and fully extended positions.
Results:
A Pearson's r correlation test was used to evaluate the criterion validity of the Cervical Range of Motion goniometer versus the radiographic method. The two measurements proved to be highly correlated (flexion: r = 0.97, P < 0.001; extension: r = 0.98, P < 0.001).
Conclusions:
For this population of healthy participants, the Cervical Range of Motion goniometer was found to be valid for measurements of cervical flexion and extension. Further research is needed on the validity of this instrument for other cervical spine movements.

Anatomical Movements
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal,...
