“…A melhora subjetiva na intensidade da dor, mensurada pela EVA, no ponto gatilho miofascial do músculo trapézio sofreu influência da LLLT, o que pode ser explicado pela eficácia dessa modalidade de tratamento em promover aumento da liberação de β-endorfinas, em nível do líquido cefalorraquidiano, e que este provavelmente é o responsável pelo efeito analgésico da energia laser (Sanchez, 2018;Hsieh, 2015).…”

O estudo avaliou a eficácia da fototerapia laser no ponto gatilho miofascial do músculo trapézio em pacientes fibromiálgicos. 25 indivíduos foram diagnosticados com dor miofascial e fibromialgia e divididos em grupos: Laser (n=8), Laser + medicamento (n=10) e Medicamento (n=7) e tratados durante 5 semanas. As variáveis mensuradas foram: 1) Intensidade da dor pela Escala Visual Analógica (EVA); 2) Limiar de dor à pressão (LDP) por meio de algômetro de pressão; 3) Estado geral da dor por meio do Questionário de Rolland-Morris (QIRM); 4) Medo de movimentar pela Escala de Tampa para Cinesiofobia (ETC) e 5) Avaliação do impacto da Fibromialgia na qualidade de vida (QIF). Os dados obtidos foram analisados por meio da análise de variância (ANOVA) de duas vias para medidas repetidas, seguida pelo pós-teste de Tukey, quando apropriado. Para os casos em que a interação entre os fatores (Tratamento e Tempo) foi significativa, foi conduzida ANOVA para medidas repetidas de uma via para cada grupo de tratamento. Todos os testes foram bi-caudais e foi considerado p<0,05. Verificou-se diminuição da intensidade da dor e aumento do LDP no músculo trapézio superior na 5ª e 10ª sessões em relação ao basal para os grupos em que a fototerapia foi utilizada. Não houve interação significativa entre os escores das variáveis QIRM, ETC e QIF entre os grupos. A escala QIF, rigidez e ansiedade, mostraram diferença significativa entre os grupos. A fototerapia laser promoveu uma diminuição da intensidade da dor local e um aumento do LDP do músculo trapézio.

“…Low-level laser therapy has a biomodulatory effect and has been indicated in cases of pain and tissue repair. 17 However, the parameters are still widely discussed in the literature, which makes it difficult to establish adequate protocols detailing the parameters in the control of neuropathic pain, especially in PTPT.…”

Justification and goals: Painful post-traumatic trigeminal neuropathy (PTPT) is characterized by neuropathic pain of traumatic origin that affects one or more branches of the trigeminal nerve, and may develop spontaneous and evoked pain from a trigger zone of moderate to severe intensity, dysesthesia, hypersensitivity, allodynia, hyperalgesia and hyperpathy. The objective of this study was to carry out a protocol of physical therapy intervention in a patient affected by NTPT relating it to functionality and pain. Case report: Male patient, 27 years old, who underwent orthognathic surgery for mandibular correction, reported an abnormal pain in the mental region, which made him search for a correct diagnosis and adequate treatment, being later diagnosed as having chronic neuropathic pain. The combination of drugs such as antidepressants, anticonvulsants and topical anesthetics were the initial basis for pain control, however, with the permanence of pain and medication side effects, he underwent several types of treatment, but did not obtain significant results. Seeking from this, a specialized treatment of physiotherapy to help him in relation to the signs and symptoms presented in the orofacial region. After 10 months of rehabilitation, totaling 40 treatment sessions, the patient had his clinical conditions modified in terms of pain and motor function. Conclusion:The protocol proposed in this study proved to be effective and with good results in the treatment of PTPT, acting in the reestablishment of neuromuscular function, reduction in pain perception, drug stabilization and improvement in the patient's quality of life.

Neonatal anoxia is a well-known world health problem that results in neurodevelopmental deficits, such as sensory alterations that are observed in patients with cerebral palsy and autism disorder, for which oxygen deprivation is a risk factor. Nociceptive response, as part of the sensory system, has been reported as altered in these patients. To determine whether neonatal oxygen deprivation alters nociceptive sensitivity and promotes medium-and long-term inflammatory feedback in the central nervous system, Wistar rats of around 30 h old were submitted to anoxia (100% nitrogen flux for 25 min) and evaluated on PND23 (postpartum day) and PND90. The nociceptive response was assessed by mechanical, thermal, and tactile tests in the early postnatal and adulthood periods. The lumbar spinal cord (SC, L4-L6) motor neurons (MNs) and the posterior insular cortex neurons were counted and compared with their respective controls after anoxia. In addition, we evaluated the possible effect of anoxia on the expression of astrocytes in the SC at adulthood. The results showed increased nociceptive responses in both males and females submitted to anoxia, although these responses were different according to the nociceptive stimulus. A decrease in MNs in adult anoxiated females and an upregulation of GFAP expression in the SC were observed. In the insular cortex, a decrease in the number of cells of anoxiated males was observed in the neonatal period. Our findings suggest that oxygen-deprived nervous systems in rats may affect their response at the sensorimotor pathways and respective controlling centers with sex differences, which were related to the used stimulus.
