Strength Exercises

Background and PurposeMuscle-specific strength training has previously been shown to be effective in the rehabilitation of chronic neck muscle pain in women. The aim of this study was to determine the level of activation of the neck and shoulder muscles using surface electromyography (EMG) during selected strengthening exercises in women undergoing rehabilitation for chronic neck muscle pain (defined as a clinical diagnosis of trapezius myalgia).SubjectsThe subjects were 12 female workers (age=30–60 years) with a clinical diagnosis of trapezius myalgia and a mean baseline pain intensity of 5.6 (range=3–8) on a scale of 0 to 9.MethodElectromyographic activity in the trapezius and deltoid muscles was measured during the exercises (lateral raises, upright rows, shrugs, one-arm rows, and reverse flys) and normalized to EMG activity recorded during a maximal voluntary static contraction (MVC).ResultsFor most exercises, the level of muscle activation was relatively high (>60% of MVC), highlighting the effectiveness and specificity of the respective exercises. For the trapezius muscle, the highest level of muscle activation was found during the shrug (102±11% of MVC), lateral raise (97±6% of MVC), and upright row (85±5% of MVC) exercises, but the latter 2 exercises required smaller training loads (3–10 kg) compared with the shrug exercise (20–30 kg).Discussion and ConclusionThe lateral raise and upright row may be suitable alternatives to shrugs during rehabilitation of chronic neck muscle pain. Several of the strength exercises had high activation of neck and shoulder muscles in women with chronic neck pain. These exercises can be used equally in the attempt to achieve a beneficial treatment effect on chronic neck muscle pain.

Neck Disability

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.

It is hypothesized that repeated recruitment of low-threshold motor units is an underlying cause of chronic pain in trapezius myalgia. This study investigated the distribution of satellite cells (SCs), myonuclei, and macrophages in muscle biopsies from the trapezius muscle of 42 women performing repetitive manual work, diagnosed with trapezius myalgia (MYA; 44 ± 8 yr; mean ± SD) and 20 matched healthy controls (CON; 45 ± 9 yr). Our hypothesis was that muscle of MYA, in particular type I fibers, would demonstrate higher numbers of SCs, myonuclei, and macrophages compared with CON. SCs were identified on muscle cross sections by combined immunohistochemical staining for Pax7, type I myosin, and laminin, allowing the number of SCs associated with type I and II fibers to be determined. We observed a pattern of SC distribution in MYA previously only reported for individuals above 70 yr of age. Compared with CON, MYA demonstrated 19% more SCs per fiber associated with type I fibers (MYA 0.098 ± 0.039 vs. CON 0.079 ± 0.031; P < 0.05) and 40% fewer SCs associated with type II fibers (MYA 0.047 ± 0.017 vs. CON 0.066 ± 0.035; P < 0.05). The finding of similar numbers of macrophages between the two groups was not in line with our hypothesis and suggests that the elevated SC content of MYA was not due to heightened inflammatory cell contents, but rather to provide new myonuclei. The findings of greater numbers of SCs in type I fibers of muscle subjected to repeated low-intensity work support our hypothesis and provide new insight into stimuli capable of regulating SC content.
