Exercise and Low-Back Pain By Tami Janssen and Kristi Wass Mechanical low back pain affects most people at some point in their life. It can be chronic or acute, usually as a result of abnormal biomechanics or muscle imbalance. Mechanical low back pain is different from a specific injury in that there is no documented damage like herniated discs, spinal fractures, or scoliosis. Poor posture, bending or lifting incorrectly, or muscle imbalance can trigger an ache, tension, or stiffness in the low back, but you can take steps to improve your back health whether or not you‟ve already experienced mechanical low back pain. “The habit of being sedentary is causing havoc on spinal health,” explains ARFC Personal Trainer Tami Janssen, “Kyphosis, or excessive forward rounding of the shoulders, greatly reduces mobility of the thoracic spine, so the lumbar spine has to increase its range of motion.” Avoid slumping in your chair or hunching over a desk. When you have to sit, use a chair with a backrest and sit with your feet flat on the floor.1 Try using a footrest to maintain neutral spinal position and take short, hourly breaks to stretch and move around a bit.2 Restricted movement in other joints can also trigger back pain. “I‟ve seen many cases of low back pain associated with a limited range of motion in the ankle joint, or decreased mobility in the hip joint,” explains Janssen, “When motion is restricted, the low back takes the brunt of the load during walking, running, and other movements, increasing stress on the low back. Helping clients restore mobility to these other joints often decreases low back pain.” In general, moderate, low-impact activities, such as walking or swimming, can aid in recovery.3 Core and gluteal strength are important in protecting and strengthening your low back. “True spinal stability is achieved by a balanced „stiffening‟ of the entire core musculature,” Janssen explains, “Abdominal bracing can do a lot for patients with low back problems.” Gluteal amnesia is another common complication associated with low back pain. Janssen recommends exercises to enhance the integration of the posterior hip muscles to improve overall back health. “Assessing my clients‟ injury history, joint mobility, and which motions bring on or relieve pain helps us construct an exercise program specific to the cause of back pain,” says Janssen, “If pain is severe or range of motion is particularly limited, the best course of action may be to pair Physical Therapy sessions to enhance mobility and Personal Training to increase strength, stability, and endurance in a safe way.” Nutrition can also influence your likelihood to suffer low back pain. “Consume adequate calcium to keep your bones strong and healthy, and be sure to maintain an adequate level of hydration,” suggests Janssen, “Vertebral discs dehydrate throughout the day, so drink enough water to keep them hydrated.” With 85 percent of the population suffering from low back pain at some point in their life4, it is worthwhile to take steps to improve your posture, strengthen your core, and increase endurance, stability, and range of motion of your joints and core muscles today to prevent or reduce pain and risk of further injury.
