To demonstrate delayed-onset muscle soreness (DOMS) is a suitable model for the study of movement-evoked pain, we attempted to identify brain regions specifically involved in pain evoked by active and dynamic movement under DOMS condition. ⋯ Active and dynamic movement with pain selectively evoked activation of M1, pre-SMA, and parietal operculum, as assessed using DOMS. Our results demonstrate that DOMS is a promising experimental model for the study of movement-evoked pain in humans.

Observational Study
Evaluation of Two Observational Pain Assessment Tools in Chinese Critically Ill Patients.
To examine and compare the reliability and validity of two observational pain assessment tools used in a sample of Chinese critically ill patients. ⋯ Both the CPOT and the BPS are reliable and valid tools to assess pain in intubated and nonintubated critically ill Chinese patients.

To investigate the differences in pressure sensitivity in the cervical musculature including the upper trapezius, sternocleidomastoid, suboccipital, levator scapulae, and anterior scalene muscles between women with migraine and healthy controls. ⋯ This study showed generalized pressure pain hypersensitivity in the cervical musculature in women with migraine. Our findings provide support for the physical therapy treatment and evaluation of musculoskeletal cervical spine disorders in individuals with migraine and reinforce that all cervical muscles should be evaluated.

Pain diagrams are a useful tool to help physicians understand the varying presentation patterns of specific pain generators. This study is the first to describe the potential pain patterns of the glenohumeral joint (GHJ) based on responses to diagnostic image-guided GHJ injections. ⋯ Anterior or posterior shoulder and upper arm pain, or a combination of the two, is the most common pain referral area from a symptomatic shoulder joint. Referral to the lateral neck, in combination with shoulder pain, was occasionally seen. Pain referral to the forearm and hand was less common. Rarely did a symptomatic shoulder joint refer pain to the scapula or to the medial neck.

To identify potential medication management issues associated with opioid use in older Australians. ⋯ A significant evidence to practice gap exists regarding the use of opioids amongst older Australians. These findings highlight the need for a quick reference guide to support prescribers in making appropriate decisions regarding pain management in older patients with persistent pain. This should also be combined with patient and caregiver education about the importance of regular acetaminophen to manage persistent pain.
