Nonspecific neck pain (NNP) is one of the most common musculoskeletal disorders in the middle-aged group. 1 The annual incidence of NNP is between 30% and 50% of the population, and it is increasing due to sedentary lifestyle and working conditions. 1 , 2 Moreover, most people in the population

Femoral neck fracture is a serious injury that can play an important role in morbidity and mortality among individuals, especially older adults. 1 With the overall mortality rate of hip fractures at 14.0% to 21.6%, the estimated 290,000 cases expected by 2030, this injury will result in a growing

15 extremities, respectively. To date, comparable equations and tissue mass data are not yet available for the head, neck, trunk, and pelvis. Therefore, the purpose of this study was to generate and validate (using DXA) tissue mass prediction equations for the head, neck, trunk, and pelvis

Neck pain (NP) is one of the most common musculoskeletal conditions with a prevalence of 30% to 50% in adult population per year 1 leading to physical and psychosocial disabilities with a high recurrence rate. 2 Among multiple contributing factors to NP development, impaired proprioception 3 and

Impaired muscle function is thought to contribute to the high prevalence 1 and recurrence 2 of idiopathic neck pain. 3 Several studies have shown deficits in maximal strength 4 – 10 and endurance 4 , 11 – 13 of the cervical muscles in individuals with idiopathic neck pain when compared with

estimation of fat mass, lean mass, wobbling mass, and bone mineral content in the extremities of young, healthy, living humans. Corresponding tissue mass prediction equations for the head, neck, and trunk are currently not available, but would allow researchers to incorporate tissue masses into wobbling mass

The female dancer’s technique in DanceSport involves keeping the upper body and head poised in extension and left rotation. Attempting to maintain this position while dancing can lead to an extension neck injury (ENI).


The aim of this online survey was to discover the prevalence of ENI among female ballroom dancers.

Design and Participants:

Female DanceSport competitors (N = 127) completed an online survey.


Twenty-fve percent reported having ENI, and 68% of ENI occurred at competitions. Younger dancers (mean age = 20 ± 4.8 years) were significantly (p < .003) more likely to have ENI than older dancers (mean age = 34 ± 12.9 years).


ENI is prevalent in DanceSport competitors. Dance medicine professionals should consider this when designing injury prevention programs.

Interestingly, clinicians are now using smartphone applications, colloquially known as “apps,” as measurement tools in the clinical setting. 2 Smartphones are often equipped with an accelerometer

Musculoskeletal disorders are the second cause of disability globally, 1 with low back and neck pain as the most common complaints among working populations. The prevalence of these conditions has increased significantly during the last decades and will likely increase as the population ages. 2

The purpose of this study was to determine whether differences exist in EMG activity between involved and uninvolved upper trapezius muscles in participants with unilateral neck pain. Thirteen volunteers, seen by a physical therapist, gave informed consent. Surface EMG electrodes were placed on involved and uninvolved upper trapezius muscles. Root mean squared EMG activity was measured. Visual analog scales (VASs) for pain were used for each side. Reliability data indicated high ICC (2,1) but also large SEMs and CVs. EMG activity increased from resting to shrugging to abducting positions. Participants perceived greater pain on the involved side than the uninvolved side. EMG readings for individuals were consistent, however, between participants. EMG had high variability. Although participants' VAS scores were consistent with their reports of unilateral neck pain, surface EMG readings did not support the existence of increased muscle activity on the involved side.
