Thoracic adaptations for ventilation during locomotion in humans and other mammals
<p class="CxSpFirst">Bipedal humans, like canids and some other cursorial mammals, are thought to have been selected for endurance running, which requires the ability to sustain aerobic metabolism over long distances by inspiring large volumes of air for prolonged periods of time. Here we test the general hypothesis that humans and other mammals selected for vigorous endurance activities evolved derived thoracic features to increase ventilatory capacity. To do so, we investigate whether humans and dogs rely on thoracic motion to increase tidal volume during running to a greater extent than goats, a species that was not selected for endurance locomotion. We found that while all three species use diaphragmatic breathing to increase tidal volume with increasing oxygen demand, humans also use both dorsoventral and mediolateral expansions of the thorax. Dogs use increased dorsoventral expansion of the thorax, representing an intermediate between humans and goats. 3D analyses of joint morphology of 10 species across four mammalian orders also show that endurance-adapted cursorial species independently evolved more concavo-convex costovertebral joint morphologies that allow for increased rib mobility for thoracic expansion. Evidence for similarly derived concavo-convex costovertebral joints in <i>Homo erectus </i>corresponds with other evidence for the evolution of endurance running in the genus <i>Homo</i>.</p>

Development of chronic pain after posterolateral and axillary approaches for thoracic surgery: A prospective monocentric observational study
<p class="MDPI17abstract"><span>Mini-invasive thoracotomies may reduce chronic</span><span> pain and pain-related functional impairment. The aims of part 2 of the study were to assess their incidence after posterolateral and axillary thoracotomies and to identify potential factors of chronic pain. Patients undergoing a posterolateral (79 patients) or axillary (79 patients) thoracotomy between July 2014 and November 2015 were analyzed in this prospective monocentric cohort study. At the 4-month assessment, more patients had chronic pain in the posterolateral group (60.8% vs 40.5%; p=0.017). There was a significant difference between groups favoring the axillary group: less level of catastrophism (p=0.021) and less impact of pain on daily activities (globally, p=0.009; routine activities subscore, p=0.010, chosen activity subscore, p=0.030). According to a multinomial logistic model multivariable, three factors are associated with the presence of chronic pain: the presence of pain before surgery (OR=2.36, CI 95% [1.03-5.39]), a large posterolateral incision (OR=4.14 [1.25-13.72]) and the intensity of pain during mobilization of the ipsilateral shoulder at postoperative day 6 (OR=1.37 [1.10-1.70]). In conclusion, chronic pain is less frequent after an axillary approach than after a posterolateral one. Identified risk factors for chronic pain should lead to more aggressive management of preoperative and early postoperative pain and favor the mini-invasive approach.</span></p>
Early postoperative pain trajectories after posterolateral and axillary approaches for thoracic surgery: A prospective monocentric observational study
<p class="MDPI17abstract"><span>Less invasive thoracotomies may reduce early postoperative pain. The aims of this study were to identify pain trajectories from postoperative day 0 to 5 after posterolateral and axillary thoracotomies and identify potential factors related to the worst" trajectory. Patients undergoing a posterolateral (92 patients) or axillary (89 patients) thoracotomy between July 2014 and November 2015 were analyzed in this prospective monocentric cohort study. The best-fitting model resulted in four pain trajectory groups: trajectory 1, the "worst", with 29.8% of the patients with permanent significant pain; trajectory 2 with patients with low pain (32.6%), trajectory 3 with patients with a steep decrease in pain (22.7%), trajectory 4 with patients with a steep increase (14.9%). According to a multinomial logistic model multivariable analysis, some predictive factors allow differentiation between trajectory groups 1 and 2. Risk factors for permanent pain are the existence of preoperative pain (OR =6.94, CI 95% [1.54-31.27]) and scar length (OR=1.20 [1.05-1.38])). In contrast, ASA class III is a protective factor to be in group 1 (OR=0.02 [0.001-0.52]). In conclusion, early postoperative pain can be characterized by four trajectories and preoperative pain is the major factor for the worst trajectory of early postoperative pain.</span></p>

Effects of upper thoracic Mulligan mobilization on pain, range of motion and function in patients with mechanical neck pain: a randomized placebo-controlled trial

Ocak 2021 ile Mayıs 2021 arasında yürütülen çalışmaya, sahte grup, fizyoterapi grubu ve Mulligan grubuna rastgele atanan 69 katılımcı dahil edildi. Tüm gruplara, paylaşımlı fizyoterapi müdahaleleri ve germe egzersizleri ile iki haftalık, 11 seanslık bir tedavi programı uygulandı. Mulligan grubuna Mulligan RNAGS tekniği ile ek mobilizasyon uygulandı. Sahte grup, standart altı Mulligan mobilizasyonu aldı. Sonuç ölçümleri arasında Hareket Aralığı (ROM), Görsel Analog Skala (VAS) ve Boyun Engellilik İndeksi (NDI) vardı. Gruplar arasında ölçümlerde hiçbir temel fark bulunamadı. Müdahaleden sonra, tüm gruplarda ROM artmış ve VAS ve NDI skorlarında azalma görüldü (p<0,001). Mulligan grubu diğer gruplara kıyasla VAS, ROM ve NDI'da önemli ölçüde daha fazla iyileşme gösterdi (p<0,001). Sham grubu fizyoterapi grubuna kıyasla NDI ve ekstansiyon ROM'da daha fazla iyileşme gösterdi (p<0,001). Üst torasik bölgedeki Mulligan RNAGS tekniği mekanik boyun ağrısında ağrı kesici, hareket aralığı ve işlevsellik açısından faydalı olduğu kanıtlandı. Uzun vadeli etkiler popülasyon bazlı çalışmalarla daha fazla araştırılmayı hak ediyor.</span></span></p>
