Background
Musculoskeletal disorders can reduce the quality of life and work capacity. In this study, we found that better muscle strength could prevent musculoskeletal pain, including arthralgia and back & joint stiffness. The study assessed handgrip strength (HGS) in relation to low back pain and arthralgia in Kurdish men.
Methods
This cross-sectional study was conducted using data from Ravansar non-communicable diseases (RaNCD) cohort study on 2164 men aged 35-65 years. HGS was measured using a hand-held hydraulic hand grip dynamometer. Low back pain, arthralgia, and joint stiffness were evaluated by the RaNCD cohort study physician using a standard questionnaire.
Results
The results showed that 21.39% and 24.58% of studied participants had low back pain and arthralgia, respectively. Among the participants with low back pain, 14.5% had back stiffness, and among those with arthralgia, 12.8% had joint stiffness. The mean of HGS in participants with arthralgia and back & joint stiffness was significantly less than those without these disorders (P<0.001, P=0.05, and P= 0.005, respectively). Multiple-adjusted OR and 95% confidence intervals (CI) for arthralgia and back and joint stiffness across muscle strength showed the HGS increase to be associated with a lower risk of arthralgia and back &joint stiffness, but not low back pain.
Conclusions
Our results highlighted that higher HGS was associated with a lower risk of arthralgia and back & joint stiffness. However, there was no association between HGS and low back pain. Exercise and adherence to proper nutrition are suggested to enhance muscle strength in order to reduce musculoskeletal pain.
