What the literature leaves open

  • further studies on the effectiveness of the staged nursing pathway, - investigation of the long-term effects of the intervention, - exploration of the feasibility of the intervention in different clinical settings

    Behavioral recurrence mechanisms of “pain shadow memory” and nursing intervention opportunities in postherpetic neuralgia during the skin lesion regression stage · 2026 · DOI

  • Current nursing care may not adequately address the complexities of pain shadow memory in postherpetic neuralgia.

  • The neural mechanisms underlying TUS effects on pain processing are not well understood. The potential delayed effects of TUS on pain processing are not well characterized.

    Multi-focal ultrasound neuromodulation to the dorsal anterior cingulate cortex disrupts behavioural and neural pain processing · 2026 · DOI

  • The study had a small sample size, - The study had a limited follow-up period, - The study did not assess the long-term effects of TMR

    Effectiveness of pre-emptive targeted muscle reinnervation on post-amputation pain in patients undergoing above knee amputation: A randomized controlled trial · 2026 · DOI

  • There is a lack of evidence on the effectiveness of pre-emptive TMR in reducing postamputation pain, - There is a need to understand the pathophysiological mechanisms of postamputation pain

    Effectiveness of pre-emptive targeted muscle reinnervation on post-amputation pain in patients undergoing above knee amputation: A randomized controlled trial · 2026 · DOI

  • Chronic pain is a leading cause of disability worldwide. Many patients with chronic pain still require long-term opioid medications, which carry significant risks. There is a need to develop effective interventions for reducing opioid use in patients with chronic pain.

    Change in opioid use following spinal cord stimulation: a systematic review and meta-analysis · 2026 · DOI

  • There is a need to quantify changes in opioid use following spinal cord stimulation implantation for the treatment of chronic pain. There is a lack of comprehensive systematic reviews and meta-analyses on this topic. There is a need to evaluate the clinical relevance of the reduction in opioid use.

  • The lack of understanding of spinal excitability in CLBP patients. The need for a simple, noninvasive instrument for diagnosis.

    Neurophysiological assessment of spinal excitability in chronic low back pain: a case-control study · 2026 · DOI

  • Although important results presented in the current study, it should be interpreted in light of several limita- tions. First, the sample size was insufficient to support the potential of generalizing the results. Second, gener- alization is limited by the relatively homogeneous study population, which was mostly composed of residents of Sohag Governorate and for which all data were gath- ered at Sohag University Hospital. Third, the variations in the methods employed to investigate the H-reflex and the interrater variation in the findings across different research. The painful procedures used discouraged more female controls to participate in the study which made a sample bias that could affect the results we found.
