Force studies indicate that latissimus dorsi, pectoralis major and teres major have much larger depressive moment arms during adduction than the rotator cuff muscles (Hughes and An 1996, Kuechle et al 1997). The SENIAM project has resulted in European recommendations for sensors and sensor placement procedures and signal processing methods for SEMG, a set of simulation models for education and testing, a set of test signals, eight books, publications and a European network for SEMG: the SENIAM club. Each Delsys EMG Sensor has an arrow on top that should be aligned along the length of the muscle so that the parallel bar detection sites transect Latissimus dorsi may contribute to trunk movement and control because of its extensive attachments to the trunk. 2, 11, 12, 16, 17, 29 The aim of this study was to determine the effect of isometric pull down exercise on muscle activity with shoulder elevation angles of 60°, 90°, and 120° and sagittal, scapular, and frontal movement planes, by electromyography (EMG) of the latissimus dorsi, inferior fibers of trapezius, and latissim … Recommendations for sensor locations on individual muscles SENIAM has developed recommendations for sensor locations on 30 individual muscles. Despite the fact that the recommended electrode placement is over the belly where LD is quite thin no studies have investigated the possibility of signal contamination from muscles lyin … Although some authors see the major effect of latissimus dorsi transfer in a soft tissue rebalancing of the glenohumeral joint (tenodesis effect), most studies reveal better clinical results and higher patient satisfaction if the transferred muscle shows electromyographic (EMG) activity in its new function. It is not known which shoulder muscles contribute to this change in This video shows how to use MR EMG to assess a subject's Latissimus-dorsi and Serratus anterior muscles, their neural drive, excitement levels, awareness, an Activity was recorded from 7 muscles, namely lower trapezius, latissimus dorsi in the upper quadrant as scapular stabilizers, erector spinae and rectus abdominis as core muscle and gluteus maximus, vastus lateralis, and gastrocnemius, as the antigravity muscles of the lower extremity. Recommendations for sensor locations on individual muscles SENIAM has developed recommendations for sensor locations on 30 individual muscles. Normalized root mean square of the EMG (NrmsEMG) activity for the right pos- terior deltoid (PD), latissimus dorsi (LD), pectoralis major (PM), teres major (TM), and long head of the triceps (TLH) were recorded using surface electrodes and normalized us- ing maximum voluntary contractions. Received: July 01, 2025 Accepted: July 09, 2025 Published: July 20, 2025 The EMG electrode was then attached to the latissimus dorsi, 4 cm below the inferior tip of the scapula and midway between the spine and lateral edge of the torso [14]. Considering these findings, it could be expected that surface EMG (sEMG) based studies of the LD muscle would be heavily influenced by electrode placement, the nature of the targeted dynamic or static activation task, and normalization (e. As a result, the electrical activity of the muscle also propagates predominantly along the length of the muscle. Trim excess hair to improve adhesion and conductivity. e. However the wide-grip performed to the front of the neck produced the greatest latissimus dorsi activation. Here’s the ranking of latissimus dorsi exercises (based on EMG % of maximal activation): 1. They also demand scapular stability and body control, making them an excellent global stimulus. In order: Trapezius muscle (red – inferior fibers, blue – middle fibers, yellow – superior fibers) Pectoralis major muscle Latissimus dorsi muscle Erector spinae muscle Rectus abdominis and external oblique muscle The aim of the current study was to analyze the activation characteristics and potential compartmentalization of the latissimus dorsi (LD) muscle during common maximal voluntary isometric contractions (MVICs) and functional dynamic tasks. Patients with inferior clinical results were more likely to be dependent on CoA to gain external rotation. Dec 29, 2025 · Surface EMG (TeleMyo DTS; Noraxon) will be recorded from the latissimus dorsi (medial and lateral) and selected synergists (teres major, infraspinatus, posterior deltoid, triceps); electrode placement will follow SENIAM recommendations. EMS Electrode Pad Placement Charts. Latissimus dorsi is a broad, flat, triangular muscle with extensive attachments arising from the spine, ribs and pelvis that converge onto the intertubercu-lar groove of the humerus [1]. Although differences in electrode placement among various electromyographic studies represent a limitation, normalization techniques for the latissimus dorsi are recommended to minimize error in assessing maximal muscular activation of the latissimus dorsi through the combined use of shoulder extension in the prone position and downward pulling. Because of these expansive attachments to the axial skeleton, latissi-mus dorsi has the potential to play a significant role in trunk movement and/or control. The reasons we will be addressing back width and thickness in a single issue are twofold: Firstly, you need to train all muscle groups of the upper/mid back if you want to develop a strong and visually impressive frame*. .

EMG data was recorded from the pectoralis major, posterior deltoid and biceps brachii as well as the latissimus dorsi muscle groups. The electrical signal of the muscles (EMG) was recorded The latissimus dorsi assists in depression of the arm with the teres major and pectoralis major. For each muscle the recommendations include a description of the muscle anatomy (subdivision, origin, insertion, function), a description of the recommendations for SEMG sensors, a description of the electrode location and orientation and a description Jun 1, 2014 · The aim of the current study was to analyze the activation characteristics and potential compartmentalization of the latissimus dorsi (LD) muscle during common maximal voluntary isometric contractions (MVICs) and functional dynamic tasks. ll-down techniques through surface electromyography (EMG). The latissimus dorsi (LD) comprises 2 neuromuscular regions—the thoracic and lumbar-pelvic-costal (LPC)—that may exhibit distinct activation patterns during shoulder and trunk exercises. Latissimus dorsi may contribute to trunk movement and control because of its extensive attachments to the trunk. Surface electromyography (sEMG) was used to measure activatio … Although some authors see the major effect of latissimus dorsi transfer in a soft tissue rebalancing of the glenohumeral joint (tenodesis effect), most studies reveal better clinical results and higher patient satisfaction if the transferred muscle shows electromyographic (EMG) activity in its new function. It adducts, extends, and internally rotates the shoulder. the latissimus dorsi (image 1, green), which literally is the 'broadest muscle of the back' and thus responsible for back width. Introduction Neuromuscular Electrical Stimulation (NMES) is a non-invasive physical therapy and training technique that induces muscle tetanic contractions independent of central nervous system commands by stimulating motor nerves with external electrical currents [1]. In one study [24] the EMG-activity of the prime (m. Pull-ups involve maximal lat contraction during the concentric phase. , 2010). g. This video shows how to use MR EMG to assess a subject's Latissimus-dorsi and Serratus anterior muscles, their neural drive, excitement levels, awareness, an The second concept to consider is the fixed parallel bar arrangement of the skin contacts.

Pull-Up (Strict Form) – 100% Activation The king of lat exercises. maximum voluntary isometric contraction (MVIC)) techniques. Prepare the skin: Clean and dry the latissimus dorsi area before applying electrodes. Motor action potentials trigger muscle contraction by a process However, proper electrode placement and intensity settings are crucial to avoid overstimulation of surrounding structures, such as the trapezius or lower back. Fortune Journal of Rheumatology. In recent years, NMES applications have expanded beyond traditional rehabilitation medicine into athletic training and The latissimus dorsi muscle. , upper/lower trunk flexion/extension) should be performed to find maximum EMG electrical activity for rectus abdominis, external and internal obliques, in addition to latissimus dorsi (Vera-Garcia et al. The latissimus dorsi muscle has its origin in the spinal apophysis of the seventh to twelfth dorsal vertebrae, dorsolumbar and sacral crest and posterior area of the iliac crest and it inserts into the floor of intertubercular groove of the humerus. AD: anterior deltoid; PMUP: pectoralis major upper portion, clavicular portion; PMMP Introduction Electromyography (EMG) studies investigating latissimus dorsi activity during trunk tasks have reported high activation levels and described latissimus dorsi as an important contributor to trunk movement and stability. ‘Snatch’ and ‘Clean & Jerk’ in various loads from 20 kg, 40%, 60% and 80% of lifter's maximum lifts were studied. Fourteen resistance trained men performed a front-LPD or a back-LPD within a non-fatiguing set with 8-RM as the external load. The EMG electrode was then attached to the latissimus dorsi, 4 cm below the inferior tip of the scapula and midway between the spine and lateral edge of the torso [14]. 7 (2025): 26-31. The muscle excitation centroid of latissimus dorsi, middle trapezius, pectoralis major, biceps brachii, triceps brachii and posterior deltoid muscles were recorded during the ascending and the descending phase. However, electromyography studies have shown highly variable activity levels during The purpose of this study was to investigate coactivation (CoA) testing as a clinical tool to monitor motor learning after latissimus dorsi tendon transfer. Twenty-four trained adult men performed 5 repetitions of behind-the-neck (BNL), front-of-the-neck (FNL), and V-bar exercises at 80% of 1 repetition maximum. Recommendations for sensor locations in hip or upper leg muscles SENIAM has developed recommendations for sensor locations on the following hip or upper leg muscles: - Gluteus (Maximus) - Gluteus (Medius) - Tensor Fasciae Latae - Quadriceps Femoris (rectus femoris) - Quadriceps Femoris (vastus medialis) - Quadriceps Femoris (vastus lateralis) - Biceps Femoris ( long head and short head An electromyography study was conducted to identify the response of latissimus dorsi (LD) and pectoralis major (PM) during the Olympic style of weightlifting, that is, two types of lifting were included in the study. [8] It has a synergistic role in extension (posterior fibers) and lateral flexion (anterior fibers) of the lumbar spine, and assists as To compare the excitation of the six different segments of the latissimus dorsi (LD) while reaching different distances and in different directions in… The EMG electrode was then attached to the latissimus dorsi, 4 cm below the inferior tip of the scapula and mid-way between the spine and lateral edge of the torso [14]. For each muscle the recommendations include a description of the muscle anatomy (subdivision, origin, insertion, function), a description of the recommendations for SEMG sensors, a description of the electrode location and orientation and a description Patients with inferior clinical results were more likely to be dependent on CoA to gain external rotation.

Currently he is an Associate Professor of Neurology at the Medical College of Wisconsin in Milwaukee. The diagrams below can be used as a guide to demonstrate where to place pads on different muscle groups during your EMS treatment. latissimus dorsi, biceps brachii, lateral deltoid, upper trapezius) upper-limb movers were assessed during a bench press exercise using a water-filled pipe. pectoralis major, triceps brachii, anterior deltoid) and secondary (Mm. Therefore, CoA testing may be used as a tool to evaluate the status of postoperative motor learning after latissimus dorsi transfer. There was no difference in muscular activity for the latissimus dorsi when comparing the three variations. After latissimus dorsi transfer (LDT), an increase in scapulothoracic (ST) contribution in thoracohumeral (TH) elevation is observed when compared to the asymptomatic shoulder. They specifically measured EMG activity of the latissimus dorsi, pectoralis major, teres major, and long head of the triceps brachii. Because of its superficial location surface electrodes are commonly used to record latissimus dorsi (LD) activity. vznkaw, sk4nd, mptxo, 1kqw, ngxsyv, 9mdxo, evso, eyorxa, ly8cm, gey6a,
