Purpose: The aim of this paper was to evaluate the effects of breathing retraining with chest wall mobilization on the onset of accessory breathing muscle recruitment and respiratory reserve in individuals with chronic neck pain. Methods: Thirty-two participants with non-specific chronic neck pain were randomly assigned into intervention and control groups. The intervention group received 30 minutes of breathing retraining with chest wall mobilization and the control group was assigned to rest for 30 minutes. Electromyography (EMG) of upper trapezius (UT), scalene (SC), and sternocleidomastoid (SCM) muscles were recorded during respiratory excursions by cycling for 12 minutes. Measurement of maximum voluntary ventilation (MVV), chest expansion, and pain intensity were taken during normal breathing. The immediate effects within each group and between two groups were analyzed. Results: Significant improvement in respiratory reserve was observed in the intervention group compared to control group through prolonged EMG onset of accessory breathing muscles. Moreover, increase of MVV, chest expansion and decrease in pain intensity were observed. Conclusions: This research suggests that breathing patterns and chest expansion should be considered within the physical assessment of breathing retraining, and that chest wall mobilization offers clinically important improvements in patients with chronic neck pain.

Individuals with chronic neck pain (CNP) walk with a stiffer spine known to cause an increase in dynamic loading on the spine. They also exhibit altered spatiotemporal gait variables, however, it is still unclear whether flat cushioning insole, which reduces dynamic loading on the musculoskeletal system by absorbing the ground reaction force, affects gait parameters in individuals with CNP. The aim of this work was to investigate the effects of flat cushioning insole on neck pain during walking and gait parameters in individuals with CNP. Methods: Twenty-one individuals with CNP and 21 asymptomatic controls were included. Assessments of gait parameters and pain were conducted in two sessions, standard shoe only and standard shoe with flat cushioning. In both sessions, all participants performed the 10-meter walk test in two walking conditions: preferred walking, walking at maximum speed. The force sensitive insoles and the video analysis method were used to assess plantar pressure variables and spatiotemporal gait variables, respectively. Pain was assessed using the Visual Analogue Scale. Results: Our results indicated that flat cushioning reduced the maximum force and force-time integral in both groups ( p < 0.05). Flat cushioning increased walking speed and step length in both walking conditions and reduced neck pain during walking at maximum speed in individuals with CNP ( p < 0.05). In asymptomatic individuals, no difference was found in spatiotemporal gait variables between two sessions ( p > 0.05). Conclusions: These results have suggested that the use of flat cushioning insole may improve neck pain during walking and spatiotemporal gait variables in individuals with CNP.

W niniejszym opracowaniu opisano mechanizm powstawania dolegliwości bólowych kręgosłupa występujących wśród tancerzy zawodowych uprawiających trzy różne style taneczne. Przeanalizowano dane ankietowe zebrane od 71 tancerzy zawodowych: 29 tancerzy klasycznych, 14 tancerzy współczesnych oraz 28 tancerzy folklorystycznych. Z grupy liczącej 71 osób, aż 65 osób (91,6%) zgłosiło bóle kręgosłupa w różnych jego częściach i powiązało je z uprawianiem swojego zawodu. Tylko 6 osób (8,5%) nigdy nie miało dolegliwości bólowych w tym obszarze aparatu ruchowego.

This study undertakes to explain the mechanism of back pain in professional dancers specialising in three styles of dance. In order to determine the topography of back pain data collected from 71 professional dancers were analysed: 29 classical dancers, 14 modern dancers and 28 folk dancers.. In the group of 71 participants as many as 65 (91.6%) reported back pain in various parts of the spine and linked it to their profession. Only 6 participants (8.5%) never experienced pain in this area.
