“…The PPT in the present study were higher than those of Cerezo-T ellez et al 2016, who treated active TrPs, but lower than the PPT reported in TrPs in the quadriceps muscles of patients with post-meniscectomy pain (Torres-Chica et al, 2014). However, the PPT was comparable to those reported by Zuil-Escobar et al (2016) who measured the PPT of latent TrPs in the legs.…”

“…[20][21][22][23] Moreover, female predisposition to the asymptomatic form of MPS in the lower limbs has been confirmed. 24 Thus, one has to assume that nociplastic pain may result from the response to a prolonged LBLP or can develop due to mechanical posture overloading or muscle involvement during the acute phase of disc disease.…”

Background The newly proposed low back pain treatment requires case classification according to the pain mechanism (nociceptive, neuropathic or nociplastic) to determine the most effective therapeutic approach. However, there is a lack of objective tools for distinguishing these pain mechanisms. The aim of the study was to identify which symptoms, signs, and standard diagnostic parameters would allow predicting the nociplastic pain (NP) subtype among low back leg pain (LBLP) patients. Methods A retrospective analysis of an LBLP case–control study database was carried out. The presence of NP was assumed if the patient presented with myofascial pain syndrome (MPS) and developed a short-term intensive vasodilatation reaction in the perceived lower leg pain area after provocation by a minimally invasive procedure. Clinical data and standard LBLP diagnostic parameters were analyzed to classify patients as NP (+) vs NP (-). Next, to predict NP probability, logistic regression analysis and a diagnostic classification tree were constructed. Results NP was confirmed in 43.75% of LBLP patients. Women represented 95.24% of all NP (+) patients. The diagnostic classification tree indicated that NP was highly probable if the LBLP subject was female and the result of a positive straight leg raise (SLR) test was lower than 45 degrees. If the SLR test result was greater than or equal to 45 degrees, a negative result on the Bragard test would have diagnostic value. This classification tree was approved to a certain extent in the logistic regression model (deviance residuals, min: −1.8519; 1Q: −0.5551; median: −0.1907; 3Q: 0.6565 and max: 2.1058) but should be verified in a larger group of subjects. Conclusion Female sex, but not clinical data or standard diagnostic parameters, is indicative of nociplastic pain in LBLP patients. More sophisticated statistical methods, based on directly measurable parameters, should be proposed to distinguish NP involvement in LBLP.

“…Aiming to reduce location-specific variance, the search, performed by a trained investigator, was restricted to the area of TrP2 according to Travell and Simons [20], which is located near the muscle belly. The gastrocnemius muscle was chosen because a) it has been shown to exhibit the highest prevalence of latent MTrP in healthy subjects [21], and b) foam rolling is most feasible and easy to standardize at the lower extremity.…”

Latent myofascial trigger points (MTrP) have been linked to several impairments of muscle function. The present study was conducted in order to examine whether a single bout of self-myofascial release using a foam roller is effective in reducing MTrP sensitivity. Fifty healthy, pain-free subjects (26.8±6 years, 21 men) with latent MTrP in the lateral gastrocnemius muscle were included in the randomized, controlled trial. One week after a familiarization session, they were randomly allocated to three groups: (1) static compression of the most sensitive MTrP using a foam roll, (2) slow dynamic foam rolling of the lateral calf and (3) placebo laser acupuncture of the most sensitive MTrP. Treatment duration in each group was 90 seconds. The pressure pain threshold (PPT) of the most sensitive MTrP was assessed using a handheld algometer prior to and after the intervention. A repeated measures analysis of variance (3x2) did not reveal significant between-group interactions (p>.05) but showed a significant time effect (F=7.715, p<.05). While placebo and dynamic self-myofascial release did not change MTrP sensitivity (p>.05), static compression of MTrP increased the PPT (2.6±0.8 to 3.0±1.1, d=.35; p<.05). Static self_myofascial release using a foam roller might represent an alternative to reduce pressure pain of latent MTrP. Additional research should aim to extend these findings to patients and athletes with myofascial pain syndromes.
