Introduction Kinesio tape (KT), although frequently used in sports, is still a matter of debate, and the results of studies that evaluated its effects on muscle strength (MS) in athletes are still inconclusive and contradictory. Objective To evaluate the effect of a progressive KT tension protocol on knee MS in runners over an eight-week intervention. Methods Clinical trial involving 49 runners of both sexes randomized into two groups: KT (KT with progressive tension protocol) and placebo (KT without tension). The MS of knee flexors and extensors was evaluated by isokinetic dynamometer (60º/s and 90º/s) at four moments: (1) without KT; (2) with KT and without tension; (3) without KT (after 8 weeks after of intervention); (4) with KT and with tension (after 8 weeks after of intervention). Inter- and intra-group comparisons were made. The significance level adopted was 95% (p < 0.05). Results There were no significant differences in MS between the groups at any of the evaluated moments. There was a statistically significant difference in MS (60º/s) in both groups (KT and placebo) when comparing moments 4 and 2 for knee flexors, and in the placebo group between moments 4 and 2 and moments 4 and 3 for knee extensors. Conclusion The progressive tension protocol of KT was not able to intervene in the SM gain of knee flexors and extensors of runners in inter and intragroup comparisons.

Introduction: Low back pain is a disorder of musculoskeletal origin of multifactorial character, which can become chronic when it persists for more than 3 months. It is expected that 80% of the world's population will present with low back pain at some stage of life, characterizing it as a serious public health condition that requires specific interventions for treatment. Given the context, elastic banding arises, a resource that can be useful to these patients, however, its effectiveness requires that the bandage be of quality that the therapist has experience and that its application is standardized, the latter being scarce in the current literature. Thus, the present study sought to observe what would be the application of a progressive tension protocol with elastic bandage in an individual with nonspecific chronic low back pain. Methods: A 47-year-old female, caregiver of the elderly and diagnosed with nonspecific chronic low back pain participated in the study. The treatment protocol lasted 10 weeks, where the elastic bandage was applied to the participant and in the first and last session, in addition to the report of the level of pain obtained through the Numerical Pain Scale (END), the following questionnaires were used to evaluate: Oswestry Disability Index (ODI), Survey of Pain Attitude (SOPA-B) and Fear Avoidance Beliefs Questionnaire (FABQ). Conclusion: The findings suggest that the application of elastic bandage following the progressive tension protocol promoted a reduction in disability index, pain and fear of movement, such outcomes can be considered clinically relevant, given the constant search for therapeutic techniques that provide improvement in the quality of life of patients with chronic low back pain.

Introduction: Smartphone use has become a popular social communication phenomenon worldwide. Its excessive use can compromise daily routines and habits, which is associated with sleep disorders, stress, anxiety and pain. Therefore, the university student stands out, as they has a lifestyle in which it is necessary to reconcile daily activities with curriculum activities, aggravating psychosocial factors. Objective: To investigate whether smartphone addiction influences sleep quality, anxiety, depression and pain in university students. Methods: We carried out an analytical cross-sectional study. For data collection, the following self-administered questionnaires were used: Smartphone Addiction Inventory (SPAI-BR), to assess smartphone dependence; Pittsburgh Sleep Quality Index (PSQI), to evaluate sleep quality; Hospital Anxiety and Depression Scale, to assess anxiety and depression (HADS), where it was subdivided into HADS-A for anxiety and HADS-D for depression; and Numeric Rating Scale (NRS) to determine physical pain intensity. The sample consisted of 301 university students studying physiotherapy and physical education at the State University of Northern Paraná (UENP). They were divided according to the score obtained in the SPAI-BR between the “regular” group (up to 6 points) and “predisposed” to smartphone dependence (7 or more points). Results: The comparisons were statistically significant in favor of the regular group: the predisposed group obtained a higher score for the questionnaires used with an average NRS of 2.37 points, average HADS-D of 9.05 points and average HADS-A of 6.01 points. Differences between groups were statistically significant: NRS, p = 0.018; HADS-A, p = 0.001; HADS-D p = 0.001; and PSQI, p = 0.001. Conclusion: The university students analyzed in this study classified as predisposed were more prone to being addicted to their smartphone, and they were more likely to have anxiety, with a worse quality of sleep and with a greater intensity of pain.
