Lumbar hyperlordosis is 50% more accentuated with standing rather than sitting. This may cause nonspecific LBP localizing to somatic tissues (e.g., paraspinal muscles, facet joints) mediated by inflammatory mechanisms. In…
Rehabilitation approaches for MPS, including neuromuscular relaxation techniques, heat, or electrical therapy may also help. Physical treatments can also be used in the management of MPS. The “stretch and spray”…
PATHOPHYSIOLOGY The development of MPS is often associated with postural derangements, such as muscle overload, dystonia, and fatigue. Postural abnormality (e.g., scoliosis) may reflect asymmetric extensor or flexor tone in…
Herpes zoster complicates 10% of lymphomas, particularly Hodgkin disease. One in 25 active shingles patients harbor undetected carcinomas, lymphomas, or other diminished T-cell immunity pathophysiology, particularly immunosuppression with corticosteroid or…
PATHOLOGY This uncommon neuralgia has various etiologies, primarily categorized as neurogenic, vascular, muscular, or osteogenic. Parenthetically, it is important to note that the C1 root, suboccipital nerve, is entirely motor…
PATHOPHYSIOLOGY This is enigmatic; one CRPS theory suggests that cutaneous innervation is altered post-traumatically. Human pathologic studies demonstrate reduced local nociceptive fiber density with aberrant hair follicles and sweat glands…
Currently, a multistep pharmacologic approach is endorsed by some experts specializing in CPSP treatment; however, no trials are yet published, supporting a polypharmacy algorithm. Some pain physicians advocate tricyclic antidepressants…
DISINHIBITION Several local inhibitory circuits and descending inhibitory pathways serve to modulate the perception of pain. However, after peripheral nerve injury, primary afferents, dorsal horn neurons, and gamma-aminobutyric acid (GABA)ergic…
PAIN CHARACTERISTICS The patient typically reports a burning, stinging, stabbing, or shooting pain; hyperalgesia to temperature and touch are often noted. Pain may travel unilaterally from the extremities to sometimes…
Neural injury triggers a range of processes affecting primary afferent receptors, their axons and cell bodies, as well as unleashing a complex immune response in central neurons and glial cells….
