Age-related Differences on Low Back Pain and Lower Extremity Isokinetic Muscle Strength and Balance
Low back pain is one of the common problems that 80% of people experience at least once in their lifetime. Between 60% and 90% of the adult population are at risk for low back pain at some point in their lives. While most resolve within six weeks, relapses are common. Pain that lasts longer than 12 weeks is defined as chronic pain, and causes significant limitation in daily life and a high psychosocial burden due to pain. Chronic low back pain significantly limits occupational activities due to a decrease in functional status.
Although chronic low back pain is a problem locally related to the lumbar and sacroiliac joints, it is also affected by changes in the joint and muscle structure of the lower extremity or affects these structures biomechanically. It has been shown that the endurance of the gluteus maximus muscle and the flexibility of the knee and hip flexors are decreased in individuals with chronic low back pain. Studies investigating knee extensor muscle strength in individuals with low back pain in the literature have shown that the maximum voluntary contraction of the knee extensors and the isokinetic strength of the knee extensors are decreased.
