Filter by:Shoulder pain increases excitation (or activity) of the upper trapezius (UT) and reduces excitation in lower trapezius (LT). Despite inconclusive evidence, kinesio-tape (KT) is often used to modify muscular excitation within the UT and/or LT to help correct alterations in scapular position and motion associated with shoulder pain/injury. The objectives of the current study were to determine if: 1) inhibitory KT to the UT acutely increases muscle excitation (whole-muscle and spatial distribution) within the LT in healthy individuals; and 2) if loading the limb alters the magnitude of change in muscle excitation of the LT. We hypothesize that: 1) inhibitory KT application to the UT will immediately increase whole-muscle LT excitation, and result in an inferior shift in the distribution of excitation within the LT compared to no tape and sham-KT tape conditions; and 2) the magnitude of immediate increase in LT excitation with KT would be greater in the loaded condition. A repeated-measures, crossover design was used to determine the impact of KT applied to UT and load on muscle excitation of the LT. Participants were asked to perform a repeated arm elevation task during three different taping conditions: no KT, experimental KT and sham KT. Each taping condition performed the repeated arm elevation task during two loading conditions: no load and loaded with 2.3 kilograms. All six conditions were tested during one visit with the no load condition preceding the loaded condition for each taping condition. A baseline trial (no KT; N-KT) was performed first, followed by both an experimental-KT (E-KT) and sham-KT (S-KT) condition. The order of the E-KT and S-KT conditions were randomized and the order was counterbalanced. Testing for each tape condition lasted approximately 10-minutes for a total of 45-minutes per participant including screening, EMG set-up and clean-up. KT was applied to the UT and muscle excitation (EMG amplitude) was measured in the LT using one single 32-grid high-density surface electromyography (HD-sEMG) electrode during a repeated arm elevation task.
Scapular dyskinesis is defined as the loss of strength around the scapular muscle, tightness of the pectoralis minor and disruption of scapular movements. Scapular patterns of proprioceptive neuromuscular fasilition (PNF) techniques are often preferred in the rehabilitation of scapular dyskinesis. The main principals of PNF applications are defined as the autogenous inhibition, reciprocal inhibition, stress relaxation and gate control theory.The aim of this study was to investigate the effect of scapular PNF patterns on muscular strength and pectoralis minor tightness among individuals with unilateral scapular dyskinesis.
Subacromial impingement syndrome (SIS) is a common disorder of shoulder joint. SIS has been accounted for 44-65 % of all shoulder pain. It is believed that one important contributing factor is scapular dyskinesis. Patients with SIS demonstrates scapular dyskinesis, including decrease in upward rotation, scapular posterior tilt, and external rotation. Altered muscle activity of scapular muscles may contribute to scapular dyskinesis, such as increase in activity of upper trapezius, and decrease in activity of lower trapezius and serratus anterior. In addition to these changes in neuromuscular control, central nervous system may be re-organized in patients with musculoskeletal disorders. Evidence has been reported that center of gravity of motor mapping changes, corticospinal excitability decreases and inhibition increases in patients with shoulder injuries such as instability, rotator cuff tendinopathy and SIS. These corticospinal changes are believed to be related to chronicity of symptoms and lack of treatment effects. Previous studies have applied many types of treatments to SIS, such as manipulation, taping, and exercises. However, most studies mainly focused on the outcomes of pain and function, few studies investigated changes in neuromuscular control following treatments. Yet, no study has addressed how corticospinal system changes following treatment in patient with shoulder injuries. Motor skill training, which has been widely used in training healthy subjects or patients with neurological disorders, has been shown to change corticospinal systems, including increasing excitability and decreasing inhibition. To our knowledge, no study has integrated the concepts of motor skill learning into a short-term treatment or investigated the effects of motor skill training on corticospinal systems in patients with SIS. The purposes of the study are to investigate the effects of short-term motor skill training on pain, neuromuscular control, corticospinal system in patients with SIS, and also to investigate whether changes in corticospinal parameters will be related to changes in pain, function and neuromuscular control.
The aim of this study was to compare the parameters of scapular muscular endurance, scapular stabilization, scapular dyskinesia, upper extremity functional status and postural alignment of adult women aged between 40-65 years old who were performing clinical pilates exercises regularly compared with sedentary adult women in the same age group and to determine whether regular exercise had an effect on these parameters.
Shoulder instability due to muscle weakness is a common problem in disorders of the upper extremities. During arm motion, the scapula acts as a dynamic base for the humeral head. To safely move the shoulder with an exoskeleton for the upper extremities a textile orthosis was developed that stabilizes the scapula against the thorax. The support level of the orthosis is continuously manually adjustable. To test the feasibility of our design and to improve the functionality of the textile orthosis, it needs to be investigated how the orthosis acts on people affected by shoulder instability. The investigators seek to explore how people with shoulder instability respond to the orthosis, and how they may benefit from the orthosis function. Therefore, the range of motion of arm elevation will be compared in different conditions: (i) without any support, (ii) with the support of a trained therapist, and (iii) when the device is engaged at the individual's optimal support level. Additionally, pilot tests will be performed to fix different parameters in our study protocol, such as the the optimal orthosis stiffness level and the ideal number of movement repetitions.
The objective of this study is to assess the interest and the efficiency of virtual reality in functional rehabilitation of shoulder pain and shoulder injuries. Participants will follow a 12-week rehabilitation program based either on exercises or on a program integrating virtual reality. Results obtained with classical rehabilitation will be compared with the one obtained virtual reality.
The 3-dimensional position and orientation of the scapula as well as muscle activation of upper trapezius (UT), lower trapezius (LT) and serratus anterior (SA) of asymptomatic dyskinetic sportspeole will be recorded during shoulder flexion and shoulder abduction, in loaded and unloaded conditions. Participants will be assessed in standard condition and with two differents kinesiotaping techniques.
Previous studies have proposed various ways to assess scapular dyskinesis, but they were impractical in clinical setting or the validity was questioned. The novel scapulometer we developed can measure the prominence of scapular medial border and inferior angle. We would like to examine its reliability and validity in subjects with symptomatic scapular dyskinesis. The long-term, high-intensity, unilateral loading may cause overhead athletes to develop adaptive changes in shoulder kinematics, range of motion (ROM) and strength in the dominant arm. We hypothesized that these changes may be related to scapular dyskinesis. According to the previous studies, we expect electromyography (EMG) biofeedback training can help improve the ratio of muscle activation of scapular muscle.
Background: Patterns of scapular dyskinesis have unique scapular kinematics and associated muscular activation. The characteristics of scapular dyskinesis may be associated with functional disability. The investigators investigated whether the level of shoulder function and primary dysfunction items were different in each unique pattern of scapular dyskinesis. The factors associated with shoulder dysfunction in different patterns of scapular dyskinesis were identified. Methods: Participants with unilateral shoulder pain were classified as having a single dyskinesis pattern (inferior angle prominence, pattern I; medial border prominence, pattern II) or a mixed dyskinesis pattern (patterns I+II). Clinical measurements with the Flexilevel Scale of Shoulder Function (FLEX-SF score), shoulder range of motion, anterior/posterior shoulder tightness, and pectoralis minor index were recorded. These clinical measurements, 3-D scapular kinematics (electromagnetic-based motion analysis), and associated muscular activation (electromyography on the upper, middle, and lower parts of the trapezius and serratus anterior muscles) during arm elevation were analyzed for associations with functional disability.
The purpose of this study is to assess the effectiveness of global postural reeducation relative to segmental exercises in the treatment of scapular dyskinesis with cervicalgia.
