The objective of this study was to investigate somatosensory nerve fiber function by applying different quantitative sensory testing including thermal, mechanical, and vibration thresholds over latent trigger points (TrP) and in its associated referred pain area. ⋯ Assessing sensory changes over latent myofascial TrPs reveal mechanical hyperesthesia, pressure pain hyperalgesia, and vibration hypoesthesia compared with a contralateral mirror area.

Fibromyalgia (FM) is a type of chronic musculoskeletal pain without a clear peripheral origin of nociception, often associated with depression. The underlying pathophysiology involves changes in a functional network that is related to pain and emotional processing in the central nervous system. Transcranial direct current stimulation (tDCS) targeting the dorsolateral prefrontal cortex or the occipital nerve (ON) is a noninvasive neuromodulation technique capable of improving fibromyalgia symptoms. This study aims to test the effect of combining 2 targets of stimulation using tDCS. ⋯ This study suggests that adding right-anode bifrontal tDCS to ONS has no added benefit in improving fibromyalgia-related symptoms.

To identify factors associated with low back pain (LBP) in children and adolescents. ⋯ Future studies should focus on muscle characteristics, the relationship between body and backpack weights, duration of carrying the backpack, characteristics of sport practice, and which are the factors associated with specifically chronic pain.

Adverse childhood experiences (ACEs) in youth have been found to be frequently associated with several chronic illnesses, including chronic pain. However, this relationship remains poorly understood. Previous research has examined the association between ACEs and chronic pain, but these have primarily been examined in the context of adults with limited assessment of ACEs and individual pain conditions. The primary objectives of this study were to examine the incidence and psychological/pain-related correlates of ACEs in a sample of youth with chronic pain. Exploratory analyses were also examined using primary pain diagnosis and number of pain locations. ⋯ ACEs exposure in youth with chronic pain occurs frequently and can be associated with increased psychosocial but not functional impairment. Future research is needed to further examine the relationship between ACEs and chronic pain in youth in a prospective manner.

Certain forms of social support have been shown to improve pain-coping behaviors and pain outcomes in older adults with chronic pain, but little is known about the effect of social support on pain outcomes in older adults following trauma exposure. ⋯ Among older adults experiencing trauma, low perceived social support was associated with higher levels of pain at 6 weeks.
