Background: Immobilization using an abduction brace is essential for the relaxation of the rotator cuff and scapular muscles and the prevention of a retear in patients with rotator cuff tear after arthroscopic rotator cuff repair (ARCR). However, thus far, the comparison of the scapular muscle activities has not been compared among different postures under an abduction brace in patients after ARCR. Objectives: The purpose of our study was to compare the scapular muscle activities among the supine position, sitting position, and walking under an abduction brace before and after ARCR Study Design: Observational, repeated measures study. Methods: Twelve patients with full-thickness rotator cuff tears were studied. The mean patient age was 64.7 years. The scapular muscle activations of the ipsilateral limbs were measured using surface electromyography in three postures: supine position, sitting position, and walking. The integrated electromyography relative values of the upper trapezius, anterior deltoid, middle deltoid, and biceps brachii were compared preoperatively and at two weeks after ARCR. Results: The trapezius, biceps brachii, and middle deltoid in the walking showed significantly higher integrated electromyography relative values than those in the supine position, preoperatively and at two weeks after surgery. The anterior deltoid in the sitting position had significantly higher integrated electromyography relative values than those in the supine position. Conclusions: Postures affected the scapular muscle activities in ARCR patients under an abduction brace. Understanding the influence of posture on the scapular muscle ...

THE BICEPS BRACHII ROLE IN THE STABILIZATION OF THE CROSS PUNCH

In this work we analyzed whether different activations of the biceps brachii impact on the power transfer of the punch and how boxers of different skill levels activate the biceps brachii when deliver a punch according to their skill level and efficacy. Methods: we enrolled, basing on official rankings, 23 skilled (n=6) and unskilled boxers. Subjects were instructed to perform three cross punches directed to a fixed elastic target triggered by the coach whistling, and were monitored through a surface electromyography sensor (EMG) on the biceps brachii to estimate the muscular activation during the performance, and through an accelerometer placed inside the elastic impact target to estimate the impact energy. We analyzed the oscillatory content of the EMG signal in order to assess the muscular activation between skilled and unskilled boxers, and between weak and strong punches. Results: both skilled and unskilled boxers threw strong, medium and weak strikes. Skilled boxers performed better than unskilled boxers (47% vs 25% in the “strong punch” category).The EMG analysis revealed a significant increase of lower and higher frequencies (2-4 Hz and 15-17 Hz) and a decrease on the ...

EFFECTS OF GROUP EXERCISE PROGRAM ON MORPHOLOGICAL STATUS OF FEMALE UNIVERSITY STUDENTS

Research Article of Internal Journal of Sports Medicine and Rehabilitation EFFECTS OF GROUP EXERCISE PROGRAM ON MORPHOLOGICAL STATUS OF FEMALE UNIVERSITY STUDENTS Čokorilo, N.1, Vasić, G.1, Prebeg, G.2, Tomašević, D.2, and Pantelić, S.3 1Faculty of Sports and Physical Education, University of Novi Sad, Novi Sad, Serbia. 2Faculty of Sports and Physical Education, University of Belgrade, Belgrade, Serbia. 3Faculty of Sports and Physical Education, University of Niš, Niš, Serbia. The objective of the research was to determine the effects of the “Body Workout” aerobic exercises on morphological characteristics of female university students after a period of 2 months with training sessions in the duration of three hours per week. The sample of research participants was made up of female university students from the Faculty of Sports and Physical Education in Novi Sad (AGE = 22.13±0.98 years) that were actively included in the workout program. The total sample participating in the research comprised of 52 participants, 25 of which comprised the experimental group (AGE=22.11±0.89; TV=166.11±5.01) while the remaining 27 of them comprised the control group (AGE=22.45±0.78 years, TV=169.51±5.04). The experimental group followed the “Body Workout” aerobic exercises model and the control group followed the regular curriculum for the university course of Fitness (Rekreacija in Serbian) at the Faculty of Sports and Physical Education in Novi Sad. At the initial measuring, there were no statistically significant differences among the participants (P=0.41). Physical changes that occurred in the participants’ bodies during the research period of two months were followed by means of monitoring of twelve morphological characteristics. According to the research results, significant effects were determined in transformation of morphological characteristics among the members of the experimental group on the level of the entire system (P=0.00) and the individual differences could be perceived in the final measuring in variables Circumference of the lower leg ...

PHYSIOTHERAPY APPROACH IN MICROCEPHALY PATIENTS

Review Article of Internal Journal of Sports Medicine and Rehabilitation PHYSIOTHERAPY APPROACH IN MICROCEPHALY PATIENTS Maria Anita Coelho Epaminondas ¹*, Jennifer Hellen Melo Sobral¹, Juliana Marina Campelo¹, Ana Clara de Andrade Pereira¹. 1Discente do Centro Universitário Maurício de Nassau, Uninassau, Recife-PE, Brasil INDRODUCTION: Microcephaly is a neurological condition with a craniofacial anomaly where it has a reduced cephalic perimeter, resulting in malformation of the central nervous system. In 2015, Brazil registered an outbreak of the disease, mainly in the states of northeastern Brazil, causing a state of alert in the entire population and a problem for public health that after investigative studies, concluded that the responsible for the outbreak would be the Zika virus. In general, the disease may present a delay in the neuropsychomotor development, the application of an early intervention program should be done in a systematic and individual way, respecting the various changes in each case. With the physiotherapist applicability occurs the contribution with the physical and psychic benefits, creating more possibilities for psychosocial rehabilitation. OBJECTIVE: To show the approach of physiotherapy to minimize the impairment caused by microcephaly, through appropriate treatments mediating the disability of each individual. METHODOLOGY: For this summary, a study was made on the need for physiotherapy in patients with microcephaly. It was conducted by electronic research in the databases Scielo, Pubmed and Bireme RESULTS: Microcephaly is a pathology that causes severe functional and cognitive alterations, being important the rehabilitation with purpose the stimulation of the child according to the neuropsychomotor age. The conduct of any technique in the first years of life helps in the process of maturation of the central nervous system, being considered important for the development of motor, cognitive and sensory skills. The study demonstrated that in addition to early interventions, the care with an interdisciplinary health team and ...
