For lumbar spine traction, what is a common starting force range?

• A. About 25–50% of body weight, up to about 75–150 pounds
• B. 5–10 pounds
• C. 200–300 pounds
• D. 500 pounds

Answer: (A)

Starting lumbar traction uses a gentle, progressive load. The recommended starting range is about 25% to 50% of body weight, which translates to roughly 75–150 pounds for many adults, depending on their actual weight. This modest force reduces the risk of aggravating symptoms, allows the patient to tolerate the treatment, and provides a safe baseline from which to gradually increase if needed. Forces much lower, like 5–10 pounds, are unlikely to produce meaningful decompression; forces well above 150 pounds (e.g., 200–300 or 500 pounds) risk tissue injury and are not used as an initial starting point. Therefore the best choice reflects a conservative, graded approach that aligns with clinical practice for lumbar traction.
