The biggest misleading claim made on this Stair Master ad, is that it helps reduce lower back pain. There are two issues I wish to address here.First of all, the research for this benefit is inconsistent. Some studies contend that inactivity will increase dysfunction, and therefore, an active low-back pain treatment focusing on improving aerobic fitness, increasing strength and flexibility, and stabilizing the lumbar musculature, will increase recovery speed (Shiple & DiNuble, 1997). This sounds like sensible information, and would therefore support the Stair Master ad. However, other studies indicate that there is more to consider. Some concerns reflected in research indicate that exercise performed during the acute phase will slow down recovery and that the appropriate exercise is not clearly identified. Furthermore, it has been found that the nature of the back pain should also be evaluated. For example, exercise will benefit back pain resulting from mechanical origin, such as disk disease, myofascial injury, and lumbar strain or sprain. But pain resulting from more serious problems such as tumors, infections, fractures, inflammation, or neurologic syndromes may not (Shiple & DiNuble, 1997). This information can be very crucial for someone who is considering purchasing a Stair Master to relieve back pain. The ad should at least advise consumers to have their back pain evaluated by a medical doctor.Secondly, I called the 800 number listed on this Stair Master ad. When I asked them how this equipment reduces lower back pain. They responded by noting the erect position of the handles. Because the typical user will slouch over the handles of stair climbers, this Stair Master is designed to allow the user to lean on the handles for support while maintaining an erect posture, and therefore, preventing lower back pain. This information seemed to contradict the ad. However, the qualifications and knowledge of the representat...
