Provided here is a protocol that details steps to establish an animal model of chronic post-ischemia pain (CPIP). This is a well-recognized model mimicking human complex regional pain syndrome type-I. Mechanical and thermal hypersensitivities are further evaluated, as well as capsaicin-induced nocifensive behaviors observed in the CPIP rat model.

Diffuse noxious inhibitory control, temporal summation and wound hyperalgesia testing are demonstrated in the obstetric patient. These tests evaluate inhibitory and excitatory mechanisms of pain processing and are here utilized to evaluate endogenous analgesia at different time-points during pregnancy and the peripartum period to help reveal individual s risk for persistent pain.

All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Monitoring Animals for Signs of Pain and Distress Recognizing early signs of pain is essential for ethical animal research. Animals are routinely monitored using behavioral, physical, and physiological parameters that reflect...

Source: Remacle, T., et al. Treating Low Back Pain in Failed Back Surgery Patients with Multicolumn-lead Spinal Cord Stimulation. J. Vis. Exp. (2018)This video demonstrates the method of using multicolumn paddle lead spinal cord stimulation to manage chronic lower back pain in Failed back surgery syndrome (FBSS) patients. The pre-implanted lead delivers targeted electrical pulses that activate non-painful sensory pathways, interrupting pain signals and reducing pain perception.
FAQs
Symptoms can arise when rotator cuff tendons and the subacromial bursa become sensitive to load. Arm elevation, particularly when repeated or sustained, may increase irritation and contribute to altered shoulder movement. This explains why pain and reduced function may occur without clinicians identifying one single structural lesion.
Repeated or sustained elevation can increase irritation in load-sensitive shoulder tissues and may alter how the shoulder moves. The important clinical issue is therefore not only whether a person can raise the arm, but how symptoms and movement respond to that demand. This perspective helps clinicians connect aggravating activities with functional limitations and select manageable changes in activity.
Altered shoulder movement matters because it can change how load is experienced during arm elevation. In practice, clinicians consider movement alongside pain, range of motion, strength, and functional limitations rather than interpreting one finding in isolation. This broader view supports management aimed at improving tolerance and function, not simply correcting or treating a presumed isolated lesion.
Assessment combines several clinical domains: pain patterns, range of motion, strength, and the person’s functional limitations. Considering these findings together helps clinicians guide diagnosis and management while identifying how shoulder symptoms affect activities. The assessment therefore informs an individualized plan rather than relying on a single symptom or structural explanation.
Management may combine activity modification, progressive exercise, and education, with the emphasis adjusted to the individual’s presentation and goals. Activity modification can reduce aggravating demands, while progressive exercise supports a gradual approach to shoulder loading. Education helps the person understand symptoms and participate in the plan. Together, these elements aim to improve function through individualized rehabilitation.
In clinical research, the syndrome provides a framework for evaluating treatments and refining models of shoulder pain. Studies can examine how interventions affect pain, movement, strength, range of motion, or functional limitations, while recognizing that symptoms may not map to one structural lesion. This context encourages outcome assessment that reflects both symptom experience and practical shoulder function.
