To determine if in knee osteoarthritis (KOA), one session of active electrical intramuscular stimulation (a-EIMS) compared with sham causes an effect on the motor cortex excitability parameters [motor evoked potential (MEP; the primary outcome), short intracortical inhibition (SICI), intracortical facilitation (ICF) and cortical silent period (CSP)] and pain measurements [pain pressure threshold (PPT); visual analog scale (VAS) and change in numerical pain scale (NPS0-10 ) during the conditioned pain modulation (CPM)-task]. This study also set out to determine if serum brain-derived neurotrophic factor (BDNF) mediates the effect of treatment on the cortical spinal system as assessed by MEP and PPT. ⋯ The serum BDNF revealed an inverse relationship with PPT independent of the treatment group. These results suggest that a-EIMS enhanced the corticospinal inhibitory systems in cortical and infracortical pain processing sites most likely by bottom-up regulation mechanisms.

. The authors sought to determine the prevalence of chronic pain in a low socioeconomic-status rental-flat community in Singapore and its associations. In Singapore, ≥85% own homes; public rental flats are reserved for the low-income. ⋯ . In this low socioeconomic-status population, chronic pain associated with unemployment and functional limitation. There was no difference in pain prevalence between the rental-flat population and adjacent owner-occupied precincts.

. Patients with complaints of orofacial pain (OFP) often have other body pain, yet many do not report these to their providers. Uncontrolled pain at any location may impact the successful management of an OFP complaint. The objective of this study was to determine the number of pain regions throughout the body, and the underreporting of pain, in patients who presented to a tertiary military OFP clinic. ⋯ Most patients had multiple pain complaints outside the chief complaint, yet the majority did not report these until multiple forms of assessment were utilized. These data encourage the use of a pain map, a verbal pain explanation, and directed pain questioning to more accurately capture pain location and facilitate multidisciplinary care.

To evaluate whether individual types of pain (headache, stomach-ache, and backache) or multiple pains affect the odds of young people achieving the recommended 60 minutes of moderate to vigorous physical activity (MVPA) per day in a large representative sample. ⋯ Pain is associated with reduced physical activity in adolescents but this association varies according to gender, age, and the type of pain experienced.
