Métodos de avaliação da eficácia dos tratamentos para a dor

Pain is a subjective condition and, thus, difficult to measure. The best tools to assess pain are the pain evaluation questionnaires, which provide either diagnostic, pain evolution or pain intensity information. To provide information which could help differentiate between nociceptive pain and neuropathic pain is one of the most important functions of these questionnaires. The questionnaires can measure pain intensity, quality of life, or sleep quality. Quality of life and sleep are two really important characteristics to assess the pain impact on patients' life. Pain intensity assessing questionnaires combine physical evaluations with questions, providing information either from the patient sensations or clinical assessment of pain manifestations as well as the underlying biological mechanisms (such as hyperalgesia or allodynia). For example, the Pain Detect questionnaire has two parts: the patient form (intuitive, with pictures and easy understandable) and the physician form. Thus, in this questionnaire, subjective information is provided by the patient and the objective one is provided by the physician. Other pain intensity questionnaires are NPSI, DN4, LANSS or StEP. Quality of life questionnaires are versatile (can be used in different pathologies). These questionnaires include functional self-evaluation questions, and other ones associated to physical and mental health. Two of such quality of life questionnaires are SF-36 and NHP. Sleep evaluation questionnaires include quantitative features such as the number of sleep interruptions, sleep latency or sleep duration as well as qualitative characteristics such as rest sensation, mood and dreams. One of the most used sleep evaluation questionnaires is PSQI, which includes patient questions and bed-partner questions, providing information from two points of view.

Association between neuropathic pain and A-Waves in Leprosy patients with type 1 and 2 reactions

Summary: Neuropathic pain (NP) is a well-recognized feature of leprosy neuropathy. However, the diagnosis of NP is difficult using only clinical criteria. In the study reported here, by means of conventional nerve conduction studies, the authors sought for an association between long-latency responses and NP complaints in leprosy patients with type 1 and 2 reactions. Of the 27 ulnar nerves of leprosy patients, 18 with type 1 reaction (T1R) and 9 with type 2 reaction (T2R) were followed-up for 6 months before and after steroid treatment. Clinical characteristics of pain complaints and clinical function were assessed, as well as the presence of F- and A-waves of the ulnar nerve using nerve conduction studies. The clinical and the neurophysiologic findings were compared to note positive concordances (presence of NP and A-waves together) and negative concordances (absence of NP and A-waves together) before and after treatment. Both reactions presented a high frequency of A-waves (61.1% in T1R and 66.7% in T2R, P < 0.05) and prolonged F-waves (69.4% in T1R and 65.8% in T2R, P = 0.4). No concordances were seen between pain complaints and F-waves. However, significant concordances between NP and A-waves were observed, although restricted to the T2R group ([chi]2 = 5.65, P = 0.04). After treatment, there was a significant reduction in pain complaints, as well as the presence of F- and A-waves in both groups (P < 0.05 for all comparisons). In conclusion, the presence of A-waves correlates well with pain complaints of neuropathic characteristics in leprosy patients, especially in those with type 2 reaction. Probably, such response shares similar mechanisms with the small-fiber dysfunction seen in these patients with NP, such as demyelination, intraneural edema, and axonal sprouting. Further studies using specific tools for small-fiber assessment are warranted to confirm our findings.

Repeated sprint ability tests and intensity-time curvature constant to predict short-distance running performances

Anaerobic efforts are commonly required through repeated sprint during efforts in many sports, making the anaerobic pathway a target of training. Nevertheless, to identify improvements on such energetic way it is necessary to assess anaerobic capacity or power, which is usually complex. For this purpose, authors have postulated the use of short running performances to anaerobic ability assessment. Thus, the aim of this study was to find a relationship between running performances on anaerobic power, anaerobic capacity or repeated sprint ability. Methods Thirteen military performed maximal running of 50 (P50), 100 (P100) and 300 (P300) m on track, beyond of running-based anaerobic sprint test (RAST; RSA and anaerobic power test), maximal anaerobic running test (MART; RSA and anaerobic capacity test) and the W′ from critical power model (anaerobic capacity test). Results By RAST variables, peak and average power (absolute and relative) and maximum velocity were significantly correlated with P50 (r = −0.68, p = 0.03 and −0.76, p = 0.01; −0.83, p < 0.01 and −0.83, p < 0.01; and −0.78, p < 0.01), respectively. The maximum intensity of MART was negatively and significantly correlated with P100 (r = −0.59) and W′ was not statistically correlated with any of the performances. Conclusion MART and W′ were not correlated with short running performances, having a weak performance predicting probably due to its longer duration in relation to assessed performances. Observing RAST outcomes, we postulated that such a protocol can be used during daily training as short running performance predictor.
