Effects of ELDOA (Elongation Longitudinaux avec Décoaptation Ostéo-Articulaire) Versus Lumbar Mobilization on Pain, Disability, and Flexibility in Recreational Cricket Players with Mechanical Low Back Pain: A Feasibility Study

For millions of people around the world, the lower back is a source of constant ache, a limitation that turns simple movements into struggles. This pain often stems from the mechanical wear and tear of daily life or sport, where muscles, ligaments, and joints become irritated without a serious underlying disease like a fracture or tumor. In the world of cricket, this issue is particularly acute. The sport demands extreme physical actions: bowlers launch themselves with explosive force, batters twist their torsos with violent speed, and fielders dive and reach repeatedly. These movements place immense stress on the spine, often leading to mechanical low back pain that can sideline even the most enthusiastic amateur players. To help these athletes, physiotherapists rely on a toolkit of manual therapies and exercises. Two distinct approaches have gained attention: one involves a therapist using their hands to gently move the joints of the lower back, a technique known as mobilization, which aims to reduce stiffness and calm pain signals. The other is a set of active postural exercises called ELDOA, where the patient holds specific positions to create a gentle, sustained stretch along the spine, theoretically creating space between the vertebrae and improving the flow of fluids within the discs. While both methods are used in clinics, it has remained unclear which, if either, offers a better path to recovery for cricketers specifically, or if they work in similar ways.

A team of researchers set out to answer this question by designing a study focused on recreational cricket players between the ages of 18 and 35 who were suffering from mechanical low back pain. Their goal was not just to see which treatment worked better, but first to determine if a larger, more definitive study could even be organized. They recruited 50 male players from sports centers in Delhi and randomly assigned them to one of two groups. One group received the ELDOA exercises, while the other received the manual mobilization techniques. Crucially, both groups followed the exact same daily home exercise program designed to strengthen the core and improve mobility, ensuring that any differences in results would come from the specific treatment they received in the clinic. Over the course of four weeks, the players attended sessions twice a week, and their pain levels, ability to perform daily tasks, and flexibility were measured at the start and at the end of the period.

The study revealed that the recruitment process was more difficult than anticipated, as the team managed to enroll 50 participants instead of the 66 they had hoped for, a shortfall that limited the statistical power of their findings. Despite this, the results were clear in one regard: both groups improved dramatically. The players in the ELDOA group and those in the mobilization group reported significant reductions in pain, with their average pain scores dropping from a moderate level of 6 out of 10 down to 3 out of 10. Their ability to function in daily life also improved, with disability scores falling from roughly 42 percent to 26 percent. Furthermore, their physical flexibility increased noticeably; tests measuring how far they could bend forward showed gains of several centimeters, and their ability to reach forward while seated also improved. These changes were statistically significant, meaning the improvements were very unlikely to have happened by chance.

However, when the researchers compared the two groups against each other, they found no meaningful difference. The players who did the active stretching exercises improved just as much as those who received the passive hand-on therapy. This finding is important, but it must be understood with a specific caveat. Because the study did not include a third group of players who received no special treatment or only the home exercises, it is impossible to say whether the improvements came from the specific techniques, the shared home program, or simply the natural healing that occurs over time. The researchers explicitly state that they cannot conclude that the two treatments are equally effective, only that this particular study, with its smaller number of participants, could not detect a difference between them. The lack of a control group means the source of the recovery remains a mystery, and the study was not large enough to prove that one method is superior to the other.

The authors conclude that while the results are encouraging, they are preliminary. The high rate of participants who completed the study suggests that players are willing to stick with these programs, but the difficulty in finding enough volunteers indicates that future research will need to cast a wider net. The study serves as a feasibility check, confirming that a larger, more rigorous trial is possible and necessary to truly determine the best way to treat back pain in cricketers. Until such a study is conducted, with a control group and a larger number of players, the medical community cannot definitively say whether the active stretching of ELDOA or the passive mobilization of the spine is the better tool for the job. For now, the evidence suggests that both approaches, when combined with a consistent home exercise routine, can lead to substantial relief for recreational cricketers, but the specific reason for that relief remains to be fully uncovered.
