As in all age groups, NP is a common health problem in the older adults [18]. As a result of the treatment programs ofthe present study with older adults, NP decreased in a similarway in both groups. In their study on individuals withchronic mechanical NP, Said et al. reported that the MMThad a greater impact on pain reduction compared to thetraditional treatment [19]. According to the main explanationprovided for the pain-reducing effect of the mobilization,mobilization movements correct positional faults inthe bony structure and hence reduce pain [19, 20]. Somestudies have reported that spinal manipulative therapyproduces a specific hypoalgesic effect. Manipulationinducedhypoalgesia may seem to be nonopioid in nature;that is, it is not reversed by the naloxone and could notimprove tolerance to repeated stimulation. It may occur
