“…These protocols should aim to train the shoulders symmetrically, thus harmonizing dyskinesias and normalizing the activity of the cuff muscles [32,33]. As is known, SP causes a reduction in daily shoulder movements and therefore in the activation of the relative muscles, while specific training, especially if symmetrical, reactivates the muscles, particularly the supraspinatus, and implements their electrical activity, improving global joint function [34][35][36]. Although the shoulder free from SP was not the specific target of the rehabilitation that we carried out, it is not surprising that this shoulder also improved, progressively matching the values of the contralateral one, while obviously the supraspinatus RMS value increased slightly, since it was already higher at baseline.…”

Shoulder pain (SP) is a common clinical complaint among wheelchair basketball (WB) players, since their shoulders are exposed to intense overload and overhead movements. The supraspinatus tendon is the most exposed to WB-related injuries and it is primarily responsible for SP in WB athletes. In these cases, SP rehabilitation remains the main treatment, but there is still a lack of specific protocols which should be customized to WB players’ peculiarities and to the supraspinatus muscle activity monitor, and the improvement of rehabilitation outcomes is slow. Thus, the aim of this study was to verify if the improvement of supraspinatus muscle activity, monitored in real time with surface electromyography (sEMG) during the execution of therapeutic exercises, could speed up SP rehabilitation outcomes in WB players. Thirty-three athletes were enrolled. They were divided into two groups. Both groups underwent the same shoulder rehabilitation program, but only the Exercise Plus sEMG Biofeedback Group executed therapeutic exercises while the activity of the supraspinatus muscles was monitored using sEMG. Participants were evaluated at enrollment (T0), at the end of 4 weeks of the rehabilitation program (T1), and 8 weeks after T1 (T2), using the following outcome measures: supraspinatus muscle activity as root mean square (RMS), Wheelchair User’s Shoulder Pain Index (WUSPI), shoulder abduction, and external rotation range of motion (ROM). The Exercise Plus sEMG Biofeedback Group improved more and faster for all the outcomes compared to the Exercise Group. The monitoring and improvement of supraspinatus muscle activity seems to be an effective way to speed up SP rehabilitation outcomes in WB players, since it makes the performance of therapeutic exercise more precise and finalized, obtaining better and faster results in terms of recovery of shoulder function.

“…The effect of the waveform is sensitive to the target muscle. Zaluski et al [49] Know the magnitude and peak activation times for the supraspinatus and infraspinatus during general rehabilitation exercises. Supraspinatus posterior and infraspinatus superior activation levels were comparable between elastic band exercises, but their maximal activation times were specific to each exercise.…”

“…Using the Trigno is almost the same as using the Myo armband because it has a surface EMG and IMU sensor. However, Trigno has also been carried out in health research, namely rehabilitation and recognition of gait [24,25,[47][48][49][50] .…”

<p>Currently, technological developments have been used in several health cases. One technology used for health is a tool to measure the strength of muscle contractions. So far, measuring muscle contractions still uses manual methods, namely the measurement muscle strength test method. Apart from that, health workers also measure manually by feeling the muscles to be measured. The need for tools to measure muscle contractions in the medical world is quite large because these tools can be used for various needs of doctors and nurses. There are many commercialized products on the market. The first aim of this article is to review four products that are available on the market. The second aim is to provide an overview of the use of the four products that have been carried out by previous researchers and the results. This article also discusses various aspects of product specifications. The research results show that each product has its own advantages. When we compare these products, it is better for us to return to the kind of product we are looking for. For example, if we want a product with high-class features that is equipped with several games, then we can choose MyoBoy. Myo armband and Trigno™ are used to identify several movement force conditions that are influenced by muscle strength, which has been equipped with an Inertial Measurement Unit (IMU) sensor. MyoWare is used to make bionic hands or bionic legs that can be controlled using electromyography (EMG) and has a relatively economical price.</p>

“…This study considered each muscle as a single entity, but recent research has identified anatomical sub-regions in some muscles of the rotator cuff, including anterior and posterior sub-regions within supraspinatus (Roh et al 2000 ; Kim et al 2007 ) and superior, middle, and inferior sub-regions within infraspinatus (Fabrizio and Clemente 2014 ; Bacle et al 2017 ). EMG studies using intramuscular fine-wire electrodes to specifically target these sub-regions have demonstrated functional differences (Kim et al 2017 ; Cudlip and Dickerson 2018 ; Alenabi et al 2019 ; Zaluski et al 2021 ; Calver et al 2022 ). Previous research examining dynamic free weights tasks normalized to both isometric and isokinetic MVCs found significant differences when comparing the two forms of normalization for specific tasks for these sub-regions (Calver et al 2022 ).…”

This study explored effects of using isometric versus isokinetic maximal voluntary contractions (MVCs) to normalize EMG data from supraspinatus and infraspinatus subregions during isokinetic tasks. Participants performed submaximal isokinetic external rotation (ER) and scaption tasks at two speeds. Three isometric MVCs were used: seated ER; side-lying scaption; side-lying abduction. Isokinetic MVCs were performed in the same position and speeds as the experimental tasks. Data were normalized using peak EMG from reference tasks: MVC which produced the greatest amplitude overall (MEA), isometric MVC with greatest amplitude (isometric best), isokinetic MVC with greatest amplitude (isokinetic best), and the greatest amplitude from the isokinetic MVC that matched the experimental task (isokinetic matched). Mean %MVC from each experimental task/ sub-region were compared by normalization method. The isokinetic matched method versus the MEA method was significantly different in all comparisons with isokinetic matched resulting in relative normalized task values up to 162% greater. The isometric best method resulted in significantly greater %MVC 37% of the time compared to the MEA method, whereas there were no differences when using isokinetic best compared to MEA. Isokinetic MVCs are less likely to overestimate %MVC than isometric and their use should be considered when normalizing data from dynamic tasks.
