The current qualitative study sought to obtain an in-depth understanding of how Arab-Americans conceptualize perceived injustice concerning their chronic low back pain (CLBP) by reflecting on the Injustice Experience Questionnaire (IEQ). Twelve Arab-American adults with CLBP were recruited from a metropolitan area in Alabama using a purposive sampling technique. Participants took part in individual, face-to-face, semi-structured interviews reflecting on each statement from the IEQ. ⋯ Additional exploration of the cultural appropriateness of the IEQ among individuals of Arab background is needed to further elaborate on the subject of faith and religious belief suggested by the current study. Perspective: Although the study findings largely reflected established injustice literature constructs, several emergent themes regarding pain-related injustice appraisal were influenced by the participants' culture and religious beliefs. These findings may indicate that specific psychotherapeutic approaches that have been proven effective among some groups may not function similarly in other populations.

Work-related musculoskeletal disorders associated with intense repetitive tasks are highly prevalent. Painful symptoms associated with such disorders can be attributed to neuropathy. In this study, we characterized the neuronal discharge from the median nerve in rats trained to perform an operant repetitive task. ⋯ Such aberrant neuronal activity may underlie painful symptoms in patients with work-related musculoskeletal disorders. PERSPECTIVE: Aberrant neuronal activity, similar to that reported in this study, may contribute to upper limb pain and dysfunction in patients with work-related musculoskeletal disorders. In addition, profiles of instantaneous frequencies may provide an effective way of stratifying patients with painful neuropathies.
