Context:A winged scapula (WS) is associated with faulty posture caused by weakness of the serratus anterior (SA), which mainly acts as a scapular stabilizer muscle. It is important to accurately assess and train the SA muscle with a focus on scapula stabilizers during musculoskeletal rehabilitation of individuals with a WS.Objective:The authors examined muscle activity in the SA and pectoralis major (PM), upper trapezius (UT), and anterior deltoid (AD) as well as shoulder protraction strength during isometric shoulder protraction in individuals with and without a WS.Design:Cross-sectional study.Setting:A clinical biomechanics laboratory.Participants:In total, 27 males with no shoulder, neck, or upper-extremity pain participated.Main Outcome Measures:Isometric shoulder protraction strength was collected and surface electromyography used to measure the activity of the SA, PM, UT, and AD muscles and selective SA activity ratio to other shoulder muscles.Results:Electromyography activity of the SA muscle and shoulder protraction strength were significantly lower in individuals with a WS compared with the non-WS group (P < .05). In contrast, PM muscle activity and the PM-to-SA, UT-to-SA, and AD-to-SA ratios were significantly greater in individuals with a WS than in individuals without winging (P < .05).Conclusions:Isometric shoulder protraction for measuring SA strength in individuals with a WS should focus on isolated muscle activity of the SA, and SA strengthening exercises are important for individuals with a WS.

Context:Scapular bracing can correct scapular kinematics and restore normal scapular-muscle activity. However, there is little evidence to support the beneficial effects of a figure-8 strap, a type of scapular bracing, on muscle length, scapular alignment, and muscle activity during arm-lifting exercise.Objective:To investigate the immediate effect of a figure-8 strap on pectoralis minor length, scapular alignment, and scapular upward-rotator-muscle activity.Design:Cross-sectional study.Setting:Research laboratory.Participants:Fifteen male participants (age 22.1 ± 1.9 y, weight 68.2 ± 5.7 kg, height 176.2 ± 3.3 cm) with forward shoulder posture (FSP) were examined for pectoralis minor length and scapular alignment with and without the application of a figure-8 strap.Main Outcome Measures:Pectoralis minor length was measured using the Pectoralis Minor Index (PMI), scapular alignment was measured with FSP, and upper trapezius, lower trapezius, and serratus anterior muscle activity were measured using surface electromyography while participants performed an arm-lifting exercise. Data collected with and without applying a figure-8 strap were compared using a paired t-test.Results:Applying a figure-8 strap significantly decreased the PMI (P = .005) and scapular anterior tilting (P = .000). There were no differences in the muscle activity of the upper trapezius (P = .784), lower trapezius (P = .241), and serratus anterior muscles (P = .639).Conclusions:A figure-8 strap resulted in positive changes in pectoralis minor length and scapular alignment. The results support its use as a treatment aid in managing pectoralis minor length and scapular alignment during arm-lifting exercises.

Purpose: People with neck pain are likely to have negative respiratory findings. The purpose of this study was to investigate the relationship between neck pain and dysfunctional breathing and to examine their relationship to stress. Method: This cross-sectional study included 49 participants with neck pain and 49 age- and sex-matched controls. We measured neck pain using the numeric rating scale (NRS); neck disability using the Neck Disability Index (NDI); dysfunctional breathing using the Nijmegen Questionnaire (NQ), Self-Evaluation of Breathing Questionnaire (SEBQ), breath hold time, and respiratory rate (RR); and stress using the Perceived Stress Scale (PSS). Results:Participants with neck pain scored higher on the NQ ( p < 0.001) and the SEBQ ( p < 0.001) than controls. NQ and SEBQ scores correlated moderately with NDI scores ( r > 0.50; 95% CI: 0.25, 0.68 and 0.33, 0.73, respectively) and PSS scores ( r > 0.50; 95% CI: 0.29, 0.78 and 0.31, 0.73, respectively). SEBQ scores showed a fair correlation with NRS scores and RR a fair correlation with NDI scores. Conclusions: Participants with neck pain had more dysfunctional breathing symptoms than participants without neck pain, and dysfunctional breathing was correlated with increased neck disability and increased stress. The NQ and SEBQ can be useful in assessing dysfunctional breathing in patients with neck pain.

Context The abdominal-bracing maneuver, a volitional preemptive abdominal contraction (VPAC) strategy, is commonly used during resisted shoulder exercises. How VPAC affects shoulder-muscle function during resisted shoulder exercise is unknown. Objective To identify the effects of VPAC on selected parascapular and glenohumeral muscles during specific shoulder exercises with or without resistance. Design Cross-sectional study. Setting Clinical biomechanics research laboratory. Patients or Other Participants Twenty-two asymptomatic volunteers between 18 and 40 years of age. Intervention(s) Participants performed arm elevation in scaption and D1 shoulder-flexion (D1F) patterns with and without resistance and VPAC. Main Outcome Measure(s) Electromyography was used to test the muscle-contraction amplitudes and onset timing of the anterior deltoid, posterior deltoid, upper trapezius, lower trapezius, and serratus anterior. Muscle-response amplitudes were quantified using root mean square electromyography. Shoulder-muscle relative-onset timing was quantified in reference to kinematic elbow-movement initiation. Results The VPAC increased serratus anterior amplitude during D1F (P &lt; .001) and scaption (P &lt; .001) and upper trapezius amplitude (P &lt; .001) in scaption. All muscle amplitudes increased with resistance. The VPAC decreased muscle-onset latencies for the anterior deltoid (P &lt; .001), posterior deltoid (P = .008), upper trapezius (P = .001), lower trapezius (P = .006), and serratus anterior (P = .001) during D1F. In addition, the VPAC decreased muscle-onset latencies for the anterior deltoid (P &lt; .001), posterior deltoid (P = .007), upper trapezius (P &lt; .001), lower trapezius (P &lt; .001), and serratus anterior (P &lt; .001) during scaption. Conclusions The VPAC affected only the parascapular muscles that had the greatest scapular-stabilizing roles during the specific open chain movement we tested. It decreased latencies in all muscles. These neuromuscular changes may enhance the stability of the shoulder during D1F and scaption exercises.

Abstract Background and Purpose. Scapular muscle performance evaluated with a handheld dynamometer (HHD) has been investigated only in people without shoulder dysfunction for test-retest reliability of data obtained with a single scapular muscle test. The purpose of this study was to assess the reliability, error, and validity of data obtained with an HHD for 4 scapular muscle tests in subjects with shoulder pain and functional loss. Subjects and Methods. Subjects (N=40) with shoulder pain and functional loss were tested bymeasuring the kilograms applied with an HHD during 3 trials for muscle tests for the lower trapezius, upper trapezius, middle trapezius, and serratus anterior muscles. Concurrently, surface electromyography (sEMG) data were collected for the 4 muscles. The same procedures were performed 24 to 72 hours after the initial testing by the same tester. Muscle tests were performed 3 times, and the results were averaged for data analysis. Results. Intraclass correlation coefficients for intratester reliability of measurements of isometricforce obtained using an HHD ranged from .89 to .96. The standard error of the measure (90% confidenceinterval [CI]) ranged from 1.3 to 2.7 kg; the minimal detectable change (90% CI) ranged from 1.8 to 3.6 kg. Construct validity assessment, done by comparing the amounts of isometric muscle activity (sEMG) for each muscle across the 4 muscle tests, revealed that the muscle activity of the upper trapezius and lower trapezius muscles washighest during their respective tests. Conversely, the isometric muscle activity of the middle trapezius and serratus anterior muscles was not highest during their respective tests. Discussion and Conclusion. In people with shoulder pain and functional loss, the intrarater reliability and error over 1 to 3 days were established using an HHD for measurement of isometric force for the assessment of scapular muscle performance. Error values can be used to make decisions regarding individual patients. Construct validity was established for the lower and upper trapezius muscle tests; therefore, these tests are advocated for use. However, construct validity was not demonstrated for the serratus anterior and middle trapezius muscle tests as performed in this study. Further investigation of these muscle tests is warranted.

Background: Trapezius Myalgia is characterized by pain in the trapezius muscle. The patient suffering from myalgia usually complaints of pain, stiffness and tightness of the upper trapezius muscle. Acute or chronic neck-shoulder pain is the hallmark of this condition. The pain in the muscle usually lasts for few days or it can be even longer. The presence of spasm in upper trapezius muscle is shown by neck pain in the back of the neck and between the bases of the neck and the shoulder. This protocol has been created that describes the design of experimental study to evaluate and compare the effect of Myofascial Release (MFR) versus High-Frequency TENS for pain relief and functional improvement in subjects with Trapezius Myalgia. Methods: The participants (n=45) will be recruited in the study suffering from Trapezius Myalgia and meeting the inclusion criteria. Two groups will be formed such that group A will be treated with Myofascial Release technique and group B will be treated with High Frequency TENS modality. The protocol will cover 4 weeks of treatment. Regular assessment will be carried out on 1st and 4th week of the rehabilitation period. During the rehabilitation period, we will evaluate pain status and functional improvement and range of motion of the neck in the subject at regular intervals. Our outcome measures will be – Numerical Pain Rating Scale (NPRS) and Neck Disability Index (NDI). Discussion: The efficacy of the intervention will be evaluated by analyzing pain relief using Numerical Pain Rating Scale (NPRS) and functional improvement by using Neck Disability Index (NDI). The result of the study will significantly provide affirmation on using these modalities for treating myalgia patients.

Balance Rehabilitation

Background Strengthening exercises for the scapular muscles are used in the treatment of scapulothoracic dysfunction related to shoulder injury. In view of the intermuscular and intramuscular imbalances often established in these patients, exercises promoting lower trapezius (LT), middle trapezius (MT), and serratus anterior (SA) activation with minimal activity in the upper trapezius (UT) are recommended. Hypothesis Of 12 commonly used trapezius strengthening exercises, a selection can be performed for muscle balance rehabilitation, based on a low UT/LT, UT/MT, or UT/SA muscle ratio. Study Design Controlled laboratory study. Methods Electromyographic activity of the 3 trapezius parts and the SA was measured in 45 healthy subjects performing 12 commonly described scapular exercises, using surface electromyography. Results For each intramuscular trapezius ratio (UT/LT, UT/MT), 3 exercises were selected for restoration of muscle balance. The exercises side-lying external rotation, side-lying forward flexion, prone horizontal abduction with external rotation, and prone extension were found to be the most appropriate for intramuscular trapezius muscle balance rehabilitation. For the UT/SA ratio, none of the exercises met the criteria for optimal intermuscular balance restoration. Conclusion In cases of trapezius muscle imbalance, some exercises are preferable over others because of their low UT/LT and UT/MT ratios. Clinical Relevance In the selection of rehabilitation exercises, the clinician should have a preference for exercises with high activation of the LT and MT and low activity of the UT.

In this study, we aimed to determine if electromyography (EMG) normalization to maximal voluntary isometric contractions (MVIC) was influenced by subacromial pain in patients with subacromial impingement syndrome. Patients performed MVICs in unique testing positions for each shoulder muscle tested before and after subacromial injection of local anesthetic. In addition to collection of MVIC data, EMG data during an arm elevation task were recorded before and after injection. From a visual analog pain scale, patients had a 64% decrease in pain following the injection. Significant increases in MVICs were noted in 4 of the 7 shoulder muscles tested: anterior, middle and posterior deltoid, and lower trapezius. No significant differences were noticed for the upper trapezius, latissimus dorsi, or serratus anterior. MVIC condition (pre and post injection) had a significant influence on EMG normalization for the anterior deltoid and lower trapezius muscle. Results indicate that subacromial pain can influence shoulder muscle activity, especially for the deltoid muscles and lower trapezius. In addition, normalization to MVIC in the presence of pain can have unpredictable results. Caution should be taken when normalizing EMG data to MVIC in the presence of pain.
