Objective Patient's engagement in their own treatment has been shown to improve clinical outcomes. A better understanding of the association between self-management in multiple sclerosis (MS) and potentially modifiable psychological factors may provide clinicians with strategies to design and stimulate better patient activation for self-managing health. Therefore, in this study, we examined whether cognitive factors, namely self-efficacy, acceptance of illness, optimism, and health locus of control (HLC), are associated with self-management in MS. Methods This is a cross-sectional study. A total of 382 patients with MS who completed the MS Self-Management Scale-Revised and the questionnaires that measure self-efficacy, optimism, illness acceptance, and HLC were included in the study. Results A hierarchical multiple regression revealed that power of others' HLC (b = 0.42, P ≤ .001), optimism (b = 0.27, P ≤ .01), internal HLC (b = -0.11, P = .017), and self-efficacy (b = 0.11, P = .031), together with control variables (longer disease duration and higher disability), explained 30% of the variance in the dependent variable. Conclusions In the case of MS, self-management is associated with patient's perception that healthcare professionals control their health, higher self-efficacy, optimism, and, surprisingly, lower internal HLC. The results of this study indicate the vital role of the healthcare staff in encouraging the patients with MS toward activities related to self-management and provide new insights on the psychological intervention aimed at improving self-management by patients.

Context Patients with multiple sclerosis (MS) experience many negative, seriously aggravating disease symptoms, and hence, research studies are utmost required to improve their coping with symptoms. Our research is an attempt to show ways to increase participation of patients with MS in the treatment and treatment planning process, as well as in managing the symptoms of the disease. Objectives To examine the relationship between perception of MS impact and treatment efficacy beliefs in patients with MS and the extent to which self and illness appraisals can be regarded as mediator variables in this relationship. Methods The cross-sectional study included 278 MS patients who completed the Treatment Beliefs Scale, Multiple Sclerosis Impact Scale, Generalized Self-Efficacy Scale, Rosenberg Self-Esteem Scale, and Brief Illness Perception Questionnaire. Demographic and clinical characteristics of the participants were collected with a self-report survey. Results Illness perception and general self-efficacy mediated the relationship between perception of MS impact and treatment efficacy beliefs under the control of age and time from diagnosis. The standardized indirect effects for illness perception and general self-efficacy were −0.131 95% CI [−0.2029, −0.0739] and −0.086 95% CI [−0.1663, −0.0165], respectively. Conclusion Our results indicate that worse perception of physical condition in patients with MS is associated with more negative treatment efficacy beliefs, and that this association is mediated by self-efficacy and illness perception. To inhibit the increase of negative treatment efficacy beliefs, health care specialists can work on improving self-efficacy and illness appraisals.

Objective The objective of the study was to assess the influence of forward head posture on the mechanical parameters and pressure pain threshold of superficial neck muscles in clinically nonsymptomatic individuals with sedentary jobs. Methods Twenty-five office workers with forward head posture and 25 office workers with normal head posture were matched for sex, age, body mass index, and the nature and duration of their work and were compared at a single point. The study participants were divided into study groups on the basis of photometric craniovertebral angle measurements. The upper trapezius, sternocleidomastoid, and splenius capitis mechanical properties were assessed in the sitting position. Primary outcome measures were muscle stiffness (N/m), muscle tone (Hz), and muscle elasticity. The secondary variable was perceived pain threshold. Results No significant differences between the groups were found for biomechanical properties and perceived pain threshold in the studied muscles. Conclusion Forward head posture has no impact on muscle stiffness, tone, and elasticity, nor does it increase the pressure sensitivity of superficial neck muscles in healthy, mildly symptomatic office workers. It is most likely that not incorrect posture of the cervical spine, but probably other factors combined with forward head posture, like comorbid acute and chronic cervical pain and musculoskeletal disorders or prolonged sitting, contribute to changes in active myofascial tone and tensegrity as well as increased pressure sensitivity of neck muscles.

Background Work-related neck disorders are among the most common dysfunctions in office workers. Understanding cervical myofascial mechanical characteristics that differentiate symptomatic from asymptomatic office workers is crucial for the understanding of musculoskeletal dysfunctions in workers with neck pain. Objective To assess the effect of moderate work-related neck disorders on head posture and stiffness and perceived pain threshold of the upper trapezius (UT) and sternocleidomastoid (SCM) muscles. Design Cross-sectional study. Setting Work environment. Participants Sixteen office workers with diagnosed moderate work-related neck disorders and 16 asymptomatic office workers matched for sex, age, body mass index, and the nature and duration of their work. Intervention Not applicable. Outcome The primary outcome measure consisted of measurements of head posture using craniovertebral angle and myotonometric muscle stiffness (Newtons per meter) of the UT and SCM muscles. The secondary output variable was the perceived pain threshold algometry of the studied muscles. Results Compared with controls, subjects with work-related neck pain had a significantly smaller craniovertebral angle (by 8.3%; Cohen d = 0.88, P = .02) and greater stiffness of the UT myofascial tissue (by 11.3%; Cohen d = 1.05, P = .006). No significant differences in perceived pain threshold of the myofascial tissue of the UT or SCM muscles were found between groups. Conclusion In this study female office workers with neck pain had increased anterior positioning of the head and stiffness of the UT muscle in the sitting posture, which was not associated with changes in the pressure pain threshold of this muscle.

The aim of this study was to analyze the effects of aging on the viscoelastic properties of the upper trapezius (UT) and the sternocleidomastoid (SCM) muscle during transition from lying to sitting position.The study included 39 older (mean age 67±5.9years) and 36 younger (21.1±1.8years) women. Tone, stiffness and elasticity of the UT and the SCM were measured by means of myotonometry (MyotonPRO) in lying and then, in sitting position. The results were compared using two-way analysis of variance.Irrespective of the position, older women presented with significantly higher muscle tone, stiffness and elasticity than younger subjects (P0.05). In both groups, the transition from lying to sitting position resulted in a decrease (P0.05) in the tone and stiffness, but not the elasticity (P0.05) of the SCM, and stimulated an increase in the tone, stiffness and elasticity of the UT (P0.05). The degree of changes in both study groups was similar, except from the absolute value of the UT elasticity, significantly higher increase in older women than in younger subjects (P0.05).Age contributes to an increase in the stiffness and tone of the UT and the SCM, as well as to a decrease in the elasticity of these muscles in female subjects. In contrast, age exerts only a slight effect on the mechanical properties of both muscles during transition from lying to sitting position.

Background Regular Nordic Walking training could improve fitness and reduce tenderness in selected muscle groups in office workers. Objective An assessment of the effects of a 12-week Nordic Walking training program on the perceived pain threshold (PPT) and the flexibility of selected upper-body muscle groups in postmenopausal female office workers. Methods 39 office workers were selected at random for the treatment group (NWg, n = 20) and the control group (Cg, n = 19). The persons from the NW group completed a 12-week Nordic Walking training program (3 times a week/1 hour). PPTs measurements in selected muscles and functional tests evaluating upper-body flexibility (Back Scratch - BS) were carried out twice in every participant of the study: before and after the training program. Results A significant increase in PPT (kg/cm2) was observed in the following muscles in the NW group only: upper trapezius (from 1,32 kg/cm2 to 1,99 kg/cm2), mid trapezius (from 2,92 kg/cm2 to 3,30 kg/cm2), latissimus dorsi (from 1,66 kg/cm2 to 2,21 kg/cm2) and infraspinatus (from 1,63 kg/cm2 to 2,93 kg/cm2). Moreover, a significant improvement in the BS test was noted in the NW group compared with the control group (from -1,16±5,7 cm to 2,18±5,1 cm in the NW group vs from -2,52±6,1 to -2,92±6,2 in the control group). Conclusions A 12-week Nordic Walking training routine improves shoulder mobility and reduces tenderness in the following muscles: trapezius pars descendens and middle trapezius, infraspinatus and latissimus dorsi, in female office workers.

The purpose of this study was to assess the effect of Nordic walking training on the indices of bone and carbohydrate metabolism in relation to 25(OH)D levels in postmenopausal women that were subjected to the outdoor systematic physical activity. The study was performed in 10 postmenopausal women, who participated in a 12-week Nordic walking exercise program, taking place during spring months (March to June). Anthropometric and biochemical parameters were measured before and after the training program. Serum concentrations of 25-hydroksycholekalciferol (25(OH)D), parathyroid hormone (PTH), insulin, glucose, osteocalcin (OC), C-terminal telopeptide of type I collagen (CTX), and calcium were determined. After the Nordic walking exercise program, a significant increase in the serum levels of 25(OH)D and CTX and a decrease in body mass, body mass index (BMI), fat mass, and PTH concentrations were observed. The findings of the present study suggest that 25(OH)D, as important metabolic regulator, plays a role in the modification of bone markers&rsquo, responses after the outdoor training program, independent of the physical activity effects.

The aim of this work was to analyze postural stability of girls having progressive form of idiopathic scoliosis and undergoing specific period of the adolescent growth spurt. Twenty-seven girls, aged 13.4 ± 1.2 years, presenting structural idiopathic scoliosis, thoracic or thoracolumbar pattern, radiological Cobb angle 41.7 ± 17.4° (study group) and 37 healthy girls (control group) were included. The groups were sex, age, height, weight, and BMI matched. Postural stability examination was performed using two stabilometric platforms with visual control (eyes open) at three stages: (1) both legs’ stance, (2) left leg stance, and (3) right leg stance. The Center of Pressure (COP) sway path length, the area and the displacement amplitude were compared. For the double stance, no difference in postural stability parameters between the groups was found. However, for the right leg stance, the total sway path length was longer (p=0.04) and the mean amplitude of the lateral COP displacement was increased (p=0.03) in the scoliotic group. In conclusion, for double stance, the adolescent girls with progressive form of idiopathic scoliosis revealed fair postural stability compared to control group. An impaired postural control was observed during right leg stance.

This study determined relationships between age, BMI and cranio-vertebral angle (CVA) (independent variables) and stiffness and elasticity of sternocleidomasteoid [SCM] and upper trapezius [UT] (dependent variables) muscles in sitting posture in 95 women across adult life. Moreover, a stepwise regression was performed to determine to what extent the dependent variables are explained by age, BMI and CVA. Age was moderately correlated with BMI (r = 0.41), and both age and BMI were moderately negatively correlated with CVA (r = −0.54 and −0.55, respectively). High (r = 0.73) and moderate (r = 0.53) linear relationships were present between age and logarithmic decrement (inversely related to elasticity) and stiffness of SCM muscle, respectively. Low (r = 0.36) and moderate (r = 0.47) relationships were present between age and logarithmic decrement and stiffness of UT muscle, respectively. Age accounted for 53% variance in elasticity and 28.5% variance in stiffness of SCM, and for 13% variance in elasticity and 22% variance in stiffness of UT muscle. Introduction of BMI but not CVA to the model explained the variance of these parameters by additional 0–8%. Among the studied factors age is the major correlate of stiffness and elasticity of neck muscles across the adult life.
