Background The correlation between hamstring muscle shortening and nonspecific low back pain and compensatory lumbar movements is still controversial. The purpose of this study was to evaluate the association between hamstring shortness and asymmetry, pain intensity, the disability index, and compensatory lumbar movement in 60 patients with nonspecific chronic low back pain. Material/Methods Sixty patients with nonspecific low back pain participated in this study. The hamstring shortness and asymmetry, pain intensity, the disability index, and compensatory lumbar movement of the patients were assessed. The pain intensity was evaluated using a numeric pain rating scale (NPRS), active knee extension testing was performed to measure the length of the hamstring, and compensatory lumbar movement was assessed using a digital dual inclinometer. Correlation analysis was used for analysis of the obtained data. Results The hamstring length showed a negative correlation with hamstring length asymmetry, NPRS, and disability index ( P <0.05). The asymmetry of the hamstring length was positively correlated with NPRS, disability index, and compensatory lumbar rotation ( P <0.05). Lumbar flexion was positively correlated with the hamstring muscle length ( P <0.05). However, there was a negative correlation between the hamstring length asymmetry, NPRS, and disability index ( P <0.05). There was no correlation between the compensatory lumbar rotation, hamstring length, or disability index. Conclusions Compensatory flexion movements, NPRS, and disability index in patients with nonspecific chronic low back pain were associated with hamstring shortness and asymmetry. These factors should be considered when planning physical therapy for patients with nonspecific low back pain.

The purpose of this study was to prepare evidence for the prevention and management of nonspecific chronic neck pain (NSCNP) by examining the correlation between activity of daily living and physical activities of office workers with NSCNP. Design: Crossed-sectional study Methods: 89 patients with NSCNP were recruited for this study. But 2 subjects met the exclusion criteria and were dropped out, and 86 subjects finally participated. Numerical pain rating scale (NPRS) and neck disability index (NDI) were used to check the pain intensity and disability of patients with neck pain, respectively. For the activity of daily living, computer use time, sleep time, and driving time were used. To find out the physical activities of the subjects, International Physical Activity Questionnaires (IPAQ-SF) was used. Correlation analysis was performed to find out the correlation of each variable. Results: A clear positive correlation was established between computer use time and pain (p＜0.05), and a clear positive correlation was established between computer use time and disability index (p＜0.05). The correlation between NPRS and NDI and physical activity total time, high intensity activity score, moderate intensity activity score, and walking score were not statistically significant (p＞0.05). Conclusions: In treating patients with NSCNP, it is necessary to reduce the computer usage time as a professional factor or to educate the proper posture. In addition, rather than emphasizing physically comprehensive physical activity, grafting therapeutic exercise directly related to neck pain could have a more positive effect on NSCNP patients.

Objective:The purpose of this study was to investigate the correlation between activity of daily living and social psychology and work mind of office workers with non-specific chronic neck pain (NSCNP). Design: Crossed-sectional study Methods: 86 patients with NSCNP were recruited for this study. Neck disability index (NDI) and Numerical pain rating scale (NPRS) were used to check the pain intensity and disability of patients with neck pain. To find out the occupational factors of the subjects, the Korean version of Latack Coping Scale was used. And,To find out the socio-psychological factors of the subjects, the Korean version of depression anxiety stress scale (DASS-21) was used. We performed correlation for each variable. Results: The correlation between NPRS and NDI and DASS-21 Scale were clear positive correlation (p＜0.05). There was no statistical significance between the LATACK control group and the pain and disability index (p＞0.05). A clear positive correlation was established between the avoidance group of LATACK and pain (p＜0.01). Conclusions: Through this study, it is necessary to have time to manage depression, anxiety, and stress in the treatment of neck pain in office workers who spend a lot of time sitting. In addition, it is thought that there should be the ability to control oneself about one's duties in the workplace.
