Assessment of diaphragmatic function by ultrasonography in patients with systemic sclerosis and its relation to clinical parameters : A case-control study.

BACKGROUND: Diaphragmatic function can be affected in many diseases and disorders. Although systemic sclerosis (SSc) is a serious connective tissue disease that affects not only the skin but also the pulmonary and musculoskeletal systems, there is insufficient information about diaphragm function. AIMS: To compare the diaphragmatic parameters by ultrasonography (USG) in patients with SSc and healthy individuals and examine the relationship between these parameters and clinical features in patients with SSc. METHODS: This study included 13 patients with SSc and 15 healthy individuals. Muscle thickness (in deep inspiration Tins and at the end of calm expiration Texp), changes in thickness (∆T), and thickening fraction at deep breathing were evaluated by USG. Skin thickness, pulmonary function tests, respiratory muscle strength, and the perception of dyspnea were measured as clinical features. RESULTS: The results of Texp, Tins, and ∆T were similar in both groups (p > 0.05), albeit patients in the SSc group had less thickening fraction compared to the control group (79.9 ± 36.7 cm and 103.8 ± 20.6 cm, respectively, p < 0.05). The Tins, ∆T, and thickening fraction of the diaphragm were associated with skin thickness, pulmonary function test parameters, and respiratory muscle strength (p < 0.05). Besides, there was significant correlation between muscle thickening fraction and perception of dyspnea (p < 0.05). CONCLUSION: These results confirm that diaphragm thickness and contractility can be affected in patients with SSc. Therefore, ultrasonographic evaluation of the diaphragm can play a complementary role to pulmonary function test and respiratory muscle strength measurement in the diagnosis and follow-up of patients with SSc.

Physical activity and health anxiety in people with and without spinal pain during the COVID-19 lockdown: A comparison study.

OBJECTIVES: In the coronavirus disease 2019 (COVID-19) pandemic, physical inactivity and health anxiety which are common risk factors for musculoskeletal pain have become widespread due to strict precautions and isolation. Thus, we aimed to com-pare physical activity, health anxiety, and spinal pain history in people experiencing and not experiencing spinal pain during the COVID-19 lockdown. METHODS: This study was designed as a case-control study. Assessments including the Nordic Musculoskeletal Questionnaire (NMQ), the International Physical Activity Questionnaire-Short Form, and the Short Health Anxiety Inventory were performed through an online questionnaire using Google forms during the COVID-19 lockdown. We reached 494 volunteers, and 348 were eliminated by the exclusion criteria. One hundred and fifty-six participants were classified as the spinal pain group (n=70) and the asymptomatic group (n=86) based on the NMQ. RESULTS: The total amount of physical activity was less in the spinal pain group than the asymptomatic group (p<0.05). The spi-nal pain group had higher levels of health anxiety than the asymptomatic group (p<0.05). Further, the percentage of people who experienced spinal pain in the past year was higher in the spinal pain group (p<0.05). CONCLUSION: People experiencing spinal pain during the COVID-19 lockdown were physically less active and more concerned about their health. These results may be useful to improve the management of spinal pain during the lockdown or possible pandemic wave scenarios.

Comparison of ultrasonographic characteristics of deep abdominal muscles in women with and without chronic neck pain: a case-control study.

OBJECTIVES: To compare ultrasonography (USG) parameters of deep abdominal muscles (transversus abdominis-TrA, internal obliques-IO) between women with and without chronic neck pain (CNP). METHODS: Women with CNP (n=18; mean-age=37.7 years; mean-BMI=22.7 kg/m2) and asymptomatic individuals (n=18; mean-age=36.1 years; mean-BMI=21.8 kg/m2) participated in the study. The activation of the deep neck flexors (ADNF) was measured using cranio-cervical flexion test. Muscle thickness, changes in thickness (ΔT), and contraction ratio (CR) of deep abdominal muscles were evaluated by ultrasonography device in two conditions: standard-protocol and during ADNF. For each condition, ultrasound image of abdominal muscles was captured at rest and during abdominal draw-in manoeuvre (ADIM). RESULTS: Comparative statistics revealed no significant difference between groups regarding ultrasonography parameters in the standard-protocol (p>0.05). Besides, there was no difference in the CR of TrA and IO between groups in the two conditions. However, women with CNP showed less muscle thickness of TrAADIM during ADNF than the asymptomatic participants (p<0.05). The CNP group also had decreased ΔT of TrA(ADIM-rest) during ADNF compared to the asymptomatic group (p<0.05). CONCLUSIONS: The ultrasonography parameters of TrA suggest that motor control in the lumbar region is altered in women with CNP. The combination of cervical stabilization exercises with ADIM can be a novel strategy in the treatment of CNP.

Effects of stabilization exercises on disability, pain, and core stability in patients with non-specific low back pain: A randomized controlled trial.

BACKGROUND: Many studies have emphasized the importance of stabilization exercises (SE) for the management of non-specific low back pain (NSLBP), yet there is no study assessing all aspects of core stability in comparing SE and other exercises. OBJECTIVE: To investigate the effects of SE on pain and core stability by using core stability tests that focus on all aspects of core stability in patients with NSLBP. METHODS: Thirty-seven individuals with chronic NSLBP were randomly divided into two groups as SE and conventional exercises (CE). Both groups underwent the progressive exercise program three days per week for six weeks. The assessments were conducted before and after the exercise programs. The outcome measures included pain, disability, trunk strength, trunk flexor, extensor and lateral flexor endurance, function, flexibility, and motor control during eyes open/closed. RESULTS: All assessment parameters except motor control during eyes open improved after SE (p < 0.05). Also, all assessment parameters except motor control during eyes open/closed and lateral trunk endurance improved after CE (p < 0.05). When comparing groups for gain scores, there were more significant improvements in pain during activity, endurance and function after SE (p < 0.05). CONCLUSIONS: SE is more effective than CE in reducing pain during activity and improving core stability regarding functionality and endurance.

The effects of the addition of motor imagery to home exercises on pain, disability and psychosocial parameters in patients undergoing lumbar spinal surgery: A randomized controlled trial.

CONTEXT: Patients who have suffered from persistent symptoms often undergo lumbar spinal surgery (LSS). Motor imagery should be added to postoperative home exercises to reduce patient complaints. OBJECTIVE: The aim of this study was to compare the effects of home exercise plus motor imagery and only home exercise in patients undergoing LSS. DESIGN: A randomized controlled study. SETTINGS: This study was designed by researchers at Dokuz Eylul University. PARTICIPANTS: Thirty-seven patients undergoing LSS were randomized to motor imagery group (n = 19) and control group (n = 18). MAIN OUTCOME MEASURES: Pain was measured by Visual Analogue Scale, disability related to low back pain by Oswestry Disability Index, pain-related fear by Tampa Scale of Kinesiophobia, depression by Beck Depression Inventory, quality of life by World Health Organization Quality of Life Scale-Short Form (WHOQOL-BREF). All assessments were repeated in the preoperative period, three weeks after and six weeks after the surgery. INTERVENTIONS: Motor imagery group underwent home exercise plus motor imagery program applied by voice recording. Control group underwent only home exercise program. Exercise program compliance was monitored by exercise diary and telephone calls once every week. RESULTS: There was a significant improvement in pain at rest and during activity, disability, kinesiophobia, depression, physical health and psychological sub-parameters of WHOQOL-BREF between preoperative period, and the third week and sixth week in both groups (p < 0.05). When comparing groups for gain scores, there was a more significant improvement in pain during activity in motor imagery group (p < 0.05). Motor imagery should be addressed as an effective treatment after LSS.

Physical Fitness and Dynamic Balance in Medication Naïve Turkish Children with ADHD.

This study investigated physical fitness levels and dynamic balance in medication-naïve children with Attention-Deficit/Hyperactivity Disorder (ADHD). Participants were 24 medication-naïve Turkish children with ADHD (4 girls, 20 boys) and 19 typically developing (TD) Turkish children (4 girls, 15 boys). We measured physical fitness levels with the Eurofit Test Battery, body composition with the Inbody 720 Body Composition Analyzer, cognitive attention with the Stroop Test, and dynamic balance with the Y-Balance Test. We found significantly poorer dynamic balance and both upper extremity and running fitness problems among the medication-naïve Turkish children with ADHD compared to the TD group (p = 0.002; p = 0.032; p = 0.002). It may be important to adress dynamic balance and physical fitness when treating children with ADHD.

Gender differences in postural control in people with nonspecific chronic low back pain.

BACKGROUND: Many studies have reported that there are several differences between genders which may result in altered neuromuscular control. Although the existing evidence suggests that low back pain (LBP) affects the ability to control posture, there is little evidence the gender differences in postural control in people with nonspecific chronic LBP. RESEARCH QUESTION: Are there any gender differences in postural control and correlations between postural control, pain, disability, and fear of movement in people with nonspecific chronic LBP? METHODS: Static and dynamic postural control were evaluated using a computerized postural control assessment tool including assessments for limits of stability (LOS), unilateral stance, and modified clinical test of sensory interaction on balance. Pain intensity and fear of movement were assessed using a visual analogue scale and the Tampa Scale of Kinesiophobia, respectively. RESULTS: This cross-sectional study included 51 people (25 females and 26 males) with nonspecific chronic LBP. Mean reaction time in the LOS test was significantly less in male participants compared with females when adjusted for pain intensity and disability level, F(1,45) = 4.596, p = .037, ηp2 = 0.093. There was no significant difference in the remaining LOS variables as well as unilateral stance, and modified clinical test of sensory interaction on balance variables between the genders (p > .05). Many correlations were observed between the LOS variables, pain intensity, and Tampa Scale of Kinesiophobia score in female participants (p < .05). The Tampa Scale of Kinesiophobia score was also correlated with the movement velocity and endpoint excursion in the LOS test in the male participants (p < .05). SIGNIFICANCE: This study suggests that there is no difference in most of the static and dynamic postural control variables between females and males; however, higher fear of movement, and pain intensity during activity are more associated with impaired dynamic balance in females with nonspecific chronic LBP.

Assessment of sit-to-stand movement in nonspecific low back pain: a comparison study for psychometric properties of field-based and laboratory-based methods.

One of the most difficult tasks associated with the management of nonspecific low back pain (LBP) is its clinical assessment. Objective functional methods have been developed for assessment. However, few studies have used daily activities such as sit-to-stand (STS). The aim was to compare the psychometric properties of two commonly used STS assessment methods. A test-retest reliability study design was used. Participants with nonspecific LBP performed the 30-s chair stand test (30CST) and the STS test in Balance Master, which measures weight transfer, rising index and centre of gravity sway velocity. The same tests were reperformed after 48-72 h. The intraclass correlation coefficient (ICC), standard error of measurement (SEM), minimal detectable change and coefficient of variation were calculated to compare the reliability. The correlations between the tests, the Oswestry Disability Index and pain intensity were examined for validation. The 30CST had very high intrarater reliability (ICC=0.94). The variables of STS test in Balance Master had moderate intrarater reliability (ICC=0.62-0.69). There were significant correlations between the 30CST, Oswestry Disability Index and pain intensity at activity (P<0.01). The rising index was the only one variable that was significantly correlated with pain intensity at activity (P<0.05). The 30CST as the field-based method to measure STS movement was better than the laboratory-based method in terms of their psychometric properties. Moreover, the 30CST was associated with disability and pain related to LBP. The 30CST is a simple, cheap, less time consuming and psychometrically appropriate method to use in individuals with nonspecific LBP.

Developing a Reliable Core Stability Assessment Battery for Patients with Nonspecific Low Back Pain.

STUDY DESIGN: Test-retest design. OBJECTIVE: The objective was to examine the intrarater (test-retest) reliability of the core stability related tests and to develop a reliable core stability assessment battery. SUMMARY OF BACKGROUND DATA: Studies suggest that core stability exercises may improve function and decrease pain in patients with nonspecific low back pain (LBP). Reliable clinical tests are required to implement adequate rehabilitation and to evaluate results of these interventions. METHODS: The study had a test-retest design. Thirty-three different tests that might relate to core stability were identified with their mostly used protocols. Five different components of core stability including endurance, flexibility, strength, functional performance, and motor control were assessed in 38 patients with nonspecific LBP. The same testing procedure was performed again after 48 to 72 hours. Intraclass correlation coefficients (ICCs), standard error of measurement, and minimal detectable change were calculated to assess the intrarater reliability. RESULTS: The intrarater reliability of the tests ranged from little to very high (ICC = 0.08-0.98). Partial curl-up (ICC = 0.90), lateral bridge (ICC = 0.95-0.96), trunk flexor endurance (ICC = 0.97), sit and reach (ICC = 0.98), single-legged hop (ICC = 0.98-0.97), lateral step-down (ICC = 0.93-0.92), eyes open right and left leg unilateral stance (ICC = 0.97 and 0.91) tests had the highest intrarater reliability for each core stability component. CONCLUSION: The results indicated that the partial curl-up test (strength), side bridge and trunk flexor tests (endurance), sit-and-reach test (flexibility), single-legged hop, and lateral step-down (functional), unilateral stance test with eyes open (motor control) had very high intrarater reliability. A core stability assessment battery involving these tests can be used in patients with nonspecific LBP to assess all components of core stability. LEVEL OF EVIDENCE: 3.
