The aims of this study were to investigate the prevalence of neck pain among computer workers at Hail University, Saudi Arabia and to compare the cervical range of motion (ROM) of female computer workers suffering from neck pain to the cervical ROM of healthy female computer workers. One hundred and seventy-six female volunteers between 20 and 46 years of age were investigated. Fifty-six of these volunteers were staff members, 22 were administrators and 98 were students. The Cervical Range of Motion (CROM) instrument was used to measure the ROM of the cervical spine. A questionnaire was used to assess participants for the presence of neck pain. The data were analyzed using the Statistical Package for Social Sciences (SPSS) software, and the level of significant was set at p < .05 for all statistical tests. There was a high prevalence of neck pain (75%) among computer workers at Hail University, particularly among students. There were significant differences in cervical lateral flexion, rotation to the right side and protraction range between the pain and pain-free groups. Our results demonstrated that cervical ROM measurements, particularly cervical lateral flexion, rotation and protraction, could be useful for predicting changes in head and neck posture after long-term computer work.

Purpose: Correct foot structure is important due to locomotion and postural stability. The aim of this study was to determine the relationships between morphological foot structure and balance indices in a quiet standing position in women over 65 years of age. Methods: The study included 116 women aged 65-90 years. The mean age was 70.6±8.4 years and BMI 29.1±3.4 m/kg2. The measured indices included postural control while standing on both feet and photogrammetric foot evaluation. An analysis was performed of the selected foot and balance indices. Results: There were no significant differences observed in the feet structure. Certain correlations between some foot indices and the indices of postural control were noted. The increased differences in the width indices between the right and the left foot lead to balance deterioration. Larger angles of valgity and varus deformity of toes and indices describing the longitudinal arch and transverse front arch of the foot have the greatest impact on the deterioration of balance in the medio-lateral axis. Conclusions: The differences between the indices and morphological indices for the right and the left foot are not significant, which indicates the proportionate formation of feet in the individual life. The increased differences in the width indices between the right and the left foot lead to balance deterioration. Larger angles of valgity and varus deformity of toes and indices describing the longitudinal arch and transverse front arch of the foot have the greatest impact on the deterioration of balance in the medio-lateral axis.
