Introduction. Disc Protrusion (DP) is a degenerative spinal disorder. Lumbar intervertebral disc protrusion is one of the most common orthopedic injuries, leading to low back pain that radiates to the lower limbs. Physical exercise is the main element in the conservative treatment of low back pain. Objective. Comparing the effects of the McKenzie method and core stabilization exercises on the rehabilitation of patients with lumbar DP. Methods. We allocated sixty-nine patients with low back pain due to disc protrusion to the Core Group (CG), the McKenzie Group (MG), or the Core + McKenzie Group (CMG). All groups underwent three interventions per week for four weeks, totaling 12 sessions. We assessed pain intensity, hamstring flexibility, functional capacity, muscle strength, and lumbopelvic stability. Results. All intervention groups significantly reduced pain intensity and functional disability, besides improving posterior muscle chain flexibility, quality of life, trunk muscle strength, and lumbopelvic stability (p < 0.05). For functional capacity, assessed through the SF-26 Questionnaire, as well as for posture holding time in the lumbopelvic stability tests, the CG and CMG significantly improved the results compared to the MG (p < 0.05). Conclusions. The results suggest that both exercise methods were efficient in reducing pain and improving function in patients with low back pain due to disc protrusion. However, the groups that used stabilization exercises showed better results in activating lumbopelvic stabilizing muscles.
Background. Shoulder pain is a very common musculoskeletal disorder that affects many people, with rotator cuff (RC) injury as one of its main causes. Objective. To analyze the efficacy of KT, both isolated and associated with exercise, on pain and function of patients with shoulder RC injuries. Method. A randomized, blind clinical trial with sixty (60) participants with RC injuries, randomized into exercise group (EG), in which participants performed an exercise protocol; kinesio tape group (KTG), with application of the elastic bandage; and exercise + kinesio tape group (EKTG), in which participants performed both protocols. We evaluated pain intensity, active and passive mobility, muscle strength, and function. Results. All intervention groups significantly improved pain, disability, and function. Regarding the latter, EKTG showed significantly greater improvements than EG and KTG (p<0.05). In addition, EKTG improved muscle strength in all evaluated movements. Groups EG and EKTG improved range of motion in all evaluated movements, for both the right and left shoulder. Conclusions. Exercises were the basis of the treatment of RC injury. When associated with an exercise protocol, kinesio tape (KT) enhanced the effect of exercise in patients with shoulder RC injury. In isolation, KT was effective in reducing pain.

Introduction: Rotator cuff (RC) tear is an inflammatory and degenerative shoulder disease. Nicotine is a potent vasoconstrictor that decreases oxygen support in the Codman's critical zone.Methods: Nonrandomized clinical trial of 24 patients with R/CT divided into nonsmoking (n=12) and smoking (n=12) groups, which received physical therapy three times a week for four weeks. The following were evaluated: pain level, range of motion (ROM), muscle strength, and functionality. Results: Pain was reduced in the long term only in the nonsmoking group. Functionality was improved in the nonsmoking group. Smokers started the treatment with a lower ROM of forward flexion, abduction, and external rotation of the left shoulder. After the intervention, they remained with less forward flexion and abduction of the left shoulder (p<0.05). The nonsmoking group increased the ROM of bilateral forward flexion, abduction, extension, and external rotation of the right upper limb (p<0.05). In the smoking group, muscle strength was lower for forward flexion, abduction, bilateral external rotation of the shoulder, and internal rotation of the left shoulder after the interventions (p<0.05). Conclusion: Cigarette smoking worsens functional outcomes following a physical therapy program for shoulder RCT. Level of evidence: IIb.
