“…The extent of the regional involvement of these defi cits suggested to authors that central mechanisms might play a part. Further evidence of this wider central mechanism involvement is provided by the fi nding that those with CRPS also suffer with hyperacusis, as in those with FMS [35].…”

The somatosensory system is an integral component of the motor control system that facilitates the recognition of location and experience of peripheral stimuli, as well as body part position and differentiation. In chronic pain, this system may be disrupted by alterations in peripheral and cortical processing. Clinical symptoms that accompany such changes can be difficult for patients to describe and health care practitioners to comprehend. Patients with chronic pain conditions such as complex regional pain syndrome or fibromyalgia typically describe a diverse range of somatosensory changes. This article describes how sensory information processing can become disturbed in fibromyalgia syndrome and complex regional pain syndrome and how symptoms can potentially be explained by the mechanisms that generate them.

“…It might be secondary to inflammatory processes with release of cytokines and tissue-released nerve growth factor (Marinus et al, 2011;Pappagallo, 2005), or it might result from sensitization of the central nervous system, such that a normal stimulus is interpreted as noxious (Marinus et al, 2011). Although loudness hyperacusis is not always reported with complex regional pain syndrome, many of these patients do have significantly lower ULLs (de Klaver et al, 2007). This motor dysfunction has been proposed to result from an alteration of inhibitory neurotransmitter mechanisms (de Klaver et al, 2007, Marinus et al, 2011.…”

“…Thus chronic low back pain has been linked to sensitized taste (92) and more extensive complex regional pain syndrome (CRPS) to sensitized hearing (hyperacusis) (93). First evidence is now available showing alterations in affective and cognitive processing in chronic pain patients using a variety of cognitive function tests (94)(95)(96)(97).…”

Chronic pain is increasingly recognized as an undesirable outcome after surgery. Predicting risk of postoperative chronic pain, as well as chronic pain prevention or treatment, requires understanding of the processes underlying its development. Quantitative sensory testing research over the last decade has made it possible to start understanding the alterations in central pain processing associated with chronic pain and its development. Chronic pain syndromes are typically characterized by a pronociceptive state of pain processing, e.g., generalized hyperalgesia as a sign of supraspinal central sensitization and poor inhibitory or even facilitatory descending modulation. In the perioperative context, development and progression of chronic pain are accompanied by signs congruent with a shift towards a pronociceptive state. Preoperatively, hyperalgesia and poor descending inhibitory modulation appear to increase the risk of subsequent chronic pain. Postoperatively, abnormal persistence and spread of hyperalgesia, compatible with rostral neuraxial spread of central sensitization, are increasingly linked to the development and progression of chronic pain. These findings, which need further confirmation, suggest that perioperative quantitative sensory testing of pain sensitivity and pain modulation has the potential to become a valuable clinical tool for assessing risk of chronic pain development and for managing its prevention and treatment.

Hyperacusis in patients with complex regional pain syndrome related dystonia

Abstract: Hyperacusis is common among severely affected patients with CRPS related dystonia and may indicate that the disease spreads beyond those circuits related to sensory-motor processing of extremities.
