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.

Can olfactory training change the psychosocial aspects of chronic pain?

Pain and smell are the oldest senses for apperceive our environment. It is known that chronic pain and olfaction share common limbic cortical regions which are the main parts of the pain neuromatrix such as the anterior cingulate cortex, amygdala, and orbitofrontal cortex. Also, these regions point out the psychosocial aspects of chronic pain. And currently, the most challenging part of chronic pain management is the psychosocial aspect such as kinesiophobia, catastrophizing, or depression. Thus, the connection between olfaction and pain has promising clues to determining new combined therapies with odor training. According to intriguing brain imaging and genetic studies, we hypothesized that patients with chronic pain may have differentiated olfactory thresholds. Further, the additional odor training to the traditional therapeutic approach could be beneficial regarding the patients' pain perspective and psychosocial domains.

Are Static Foot Posture Measures Related to Static and Dynamic Plantar Pressure Parameters?

BACKGROUND: A few studies have investigated the relationship between foot posture measures and plantar pressure parameters, but no study has investigated the correlation of foot posture measures with all primary parameters consisting of contact area (CA), maximum force (MF), and peak pressure (PP). We aimed to determine the relationship of the Foot Posture Index-6 (FPI-6) and navicular drop (ND) with plantar pressure parameters during static standing and preferred walking. METHODS: Seventy people were included. Navicular drop and the FPI-6 were used to assess foot posture. Plantar pressure parameters including CA, MF, and PP were recorded by a pressure-sensitive mat during barefoot standing and barefoot walking at preferred speed. All assessments were repeated three times and averaged. Pearson correlation coefficients below 0.300 were accepted as negligible and higher ones were interpreted. RESULTS: Navicular drop was moderately correlated with dynamic CA under the midfoot and second metatarsal; also, the FPI-6 was moderately correlated with dynamic CA under the midfoot (0.500 < r < 0.700). The other interpreted correlations were poor (0.300 < r < 0.500). Both measures were correlated with dynamic CA under the second and third metatarsals; dynamic CA and MF under the midfoot; and static CA, MF, and PP under the first metatarsal and hallux (P < .01). Navicular drop was also correlated with dynamic MF under the first metatarsal and dynamic CA under the fourth metatarsal (P < .01). Furthermore, ND was correlated with static CA and PP under the second metatarsal and static PP under the fifth metatarsal (P < .01). The FPI-6 was also correlated with dynamic MF and PP under the hallux (P < .01). CONCLUSIONS: The correlations between foot posture measures and plantar pressure variables are poor to moderate. The measures may be useful in the clinical assessment of medial forefoot problems related to prolonged standing and midfoot complaints related to high force during walking. Furthermore, the FPI-6 may provide valuable data regarding hallux complaints related to the high loads during walking.

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.

Validity and reliability of a smartphone goniometer application for measuring hip range of motions.

BACKGROUND: Mobile applications which are designed to assess the range of motion (ROM) are widely used. OBJECTIVE: The aim of this cross-sectional observational study was to determine the inter-observer and intra-observer reliability of a smartphone application "PT Goniometer" (PTG) and determine the correlation between PTG and universal goniometer (UG) regarding active ROMs of the hip in healthy participants. METHODS: Thirty-four healthy young participants were included in the study. Two physiotherapists performed active hip flexion, abduction, internal rotation and external rotation ROM measurements of dominant legs of the participants by using PTG and UG. Intraclass correlation coefficients (ICC) were calculated to determine the intra-observer and inter-observer reliability. Level of correlations between PTG and UG were used to establish concurrent validity of PTG. RESULTS: The PTG demonstrated excellent inter-observer and intra-observer reliability (ICC > 0.90) for all measured hip movements. The minimum detectable change (MDC95) was ranged from 3.29° to 5.1° for the intra-observer reliability, and from 2.55° to 3.21° for the inter-observer reliability. Additionally, the concurrent validity was found excellent (r = 0.91-0.93). CONCLUSION: The results of the present study suggest that PTG is a valid and reliable mobile technology for measuring hip ROMs.

Investigation of balance performance under different sensory and dual-task conditions in patients with chronic neck pain.

BACKGROUND: Most studies suggest that people with chronic neck pain (CNP) have decreased balance abilities. However, balance performance during performing concurrent tasks is not clarified. OBJECTIVES: To investigate balance performance under different sensory and dual-task conditions in people with and without CNP. METHOD: Twenty-two women with CNP and twenty-two asymptomatic women were tested using the Biodex Stability System. Overall stability index (OSI), anterior/posterior stability index (APSI), medial/lateral stability index (MLSI) were obtained in two sessions: eyes-open and eyes-closed. Both sessions consisted of four conditions: quiet standing, rotating head, counting backward, standing on foam. Higher index scores mean poorer balance. DESIGN: Case-Control study. RESULTS: A mixed factorial ANOVA (2 × 8 design) showed that there was a main effect of CNP on OSI, APSI, and MLSI (p < 0.001), which indicates that CNP causes poor balance. Further, there was an interaction between CNP and test conditions for only OSI (p < 0.05). Simple effects tests showed that patients with CNP had higher OSI in all conditions except standing on foam with eyes-open, and quiet standing and counting backward with eyes-closed (p < 0.05). The largest effect size was obtained during rotating head with eyes-open (η2:0.301), followed by counting backward with eyes-open and quiet standing with eyes-open (η2:0.267 and 0.245). Performing a concurrent task, closing eyes, or standing on foam mostly increased OSI in both groups (p < 0.05). CONCLUSIONS: Patients with CNP have poorer balance under different sensory and dual-task conditions. Addressing balance assessment while performing concurrent tasks, especially head rotations, may offer new insights into the management of CNP.

Gender differences in health anxiety and musculoskeletal symptoms during the COVID-19 pandemic.

BACKGROUND: Health anxiety is often associated with musculoskeletal symptoms and gender, but there are limited studies that investigate these relationships during the COVID-19 pandemic. OBJECTIVE: We aimed to compare the genders regarding health anxiety and musculoskeletal symptoms during the COVID-19 pandemic and to investigate the relationship of musculoskeletal symptoms with physical activity and health anxiety. METHODS: Assessments were performed through an online questionnaire. Eighty-five males and eighty-five females were included by matching genders in terms of age, body mass index, education level, number of days spent at home during the pandemic, and physical activity. The Short Health Anxiety Inventory, the International Physical Activity Questionnaire-Short Form, and the Nordic Musculoskeletal Questionnaire were used to assess health anxiety, physical activity, and musculoskeletal symptoms, respectively. RESULTS: Females had a higher level of health anxiety and more musculoskeletal symptoms than males (p< 0.05). There were weak to moderate correlations in females and weak correlations in males between musculoskeletal symptoms and health anxiety (p< 0.05). Also, a weak negative correlation was found between physical activity and musculoskeletal symptoms in both genders (p< 0.05). CONCLUSIONS: Females are more anxious and have more musculoskeletal symptoms during the pandemic than males. Also, health anxiety is related to musculoskeletal symptoms in both genders.

Is the pain pressure threshold linked to the transversus abdominis in women with chronic neck pain?: a preliminary report.

PURPOSE: The present study aimed to investigate the relationship between the ultrasonography parameters of transversus abdominis and neck pain manifestations in women with chronic neck pain. MATERIALS AND METHODS: Thirty women (mean age: 38.44 ± 9.56 years, BMI: 25.57 ± 3.32 kg/m2) with chronic neck pain were included in the study. The pain severity, disability scores, and bilateral pain pressure threshold of upper trapezius were assessed. The thickness of transversus abdominis in-rest and abdominal draw-in conditions were evaluated by two-dimensional ultrasonography. Pearson's correlation coefficients and linear regression statistics were determined. RESULTS: We found a moderate correlation between the thickness of transversus abdominis in abdominal draw-in and the pain pressure threshold of right (r = 0.636, p < 0.001), and left upper trapezius (r = 0.403, p = 0.03). Moreover, there was a moderate correlation between the pain pressure threshold of the right upper trapezius and the thickness of transversus abdominis in-rest (r = 0.498, p = 0.006). No significant correlation was found between pain intensity, disability scores, and ultrasonography parameters of transversus abdominis. There was also a significant total effect of transversus abdominis' thickness on abdominal draw-in manoeuvre on predicting pain pressure threshold of right upper trapezius (B = 0.636, SE = 0.765, p < 0.001) and pain pressure threshold of left upper trapezius (B = 0.403, SE = 0.840, p = 0.03). CONCLUSIONS: Our results revealed that upper trapezius muscle tenderness may associated with decreased muscle thickness of transversus abdominis. Addressing new exercise methodologies including transversus abdominis training in the management of chronic neck pain may be helpful to improve neck pain symptoms.

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.

Cross-cultural adaptation, reliability and validity of the Turkish version of Patient-Specific Functional Scale in patients with chronic neck pain

Background/aim: Current clinical guidelines recommend to use both clinical and self-reported measurements for evaluation of chronic neck pain. Among the self-reported outcomes, Neck disability index and patient-specific functional scale are the most widely used and recommended instruments. The purpose of our study was to determine the test-retest reliability and validity of patient-specific functional scale which was not validated in Turkish language previously. Materials and methods: Translation and adaptation process had conducted according to the Beaton et al. Sociodemographic data, Turkish version of patient-specific functional scale and neck disability index were recorded at the initial assessment. Retest assessment was produced for reliability analyses and intraclass correlation coefficient (ICC3,2) was determined. The correlations between patient- specific functional scale and neck disability index and hypothesis testing were examined for the convergent and construct validity analysis. Results: The final form was completed by 110 chronic neck pain patients (Male: 33; mean ages: 43.13 ± 13.75 years, Female: 77; mean ages: 44.45 ± 14.38). Test-retest reliability of patient-specific functional scale was found good level (ICC: 0.85). The relationship between patient-specific functional scale and neck disability index was found moderate level (P < 0.05, rho: ­0.578). The median score of PSFS-T in the low disability group was significantly higher than the high disability group in the hypothesis testing of construct validity (P < 0.001). Conclusion: The Turkish version of the patient-specific functional scale is a valid and reliable scale for evaluating functional status in patients with chronic neck pain.

The effect of calling duration on cervical joint repositioning error angle and discomfort in university students.

BACKGROUND: The time spent on mobile phone during daytime is increasing with the rapid life-style in young population for different purposes such as texting, calling etc. and the younger population is more dependent on networking with them. OBJECTIVE: The aim of the present study was to compare joint repositioning error angle in the cervical region between groups with regard to their daily calling duration on smartphone and to determine the relationship between daily calling duration and potential cervical pain and disability. METHODS: Sixty-three university students were included in the study. Participants were divided concerning to their durations of daily calling durations on smartphones. The joint-repositioning-error sense, craniovertebral angle, cervicothoracic muscle strength, and endurance of neck flexors were measured and potential pain and disability levels were assessed. RESULTS: University students who spending twenty minutes or more for calling on smartphone daily had significantly higher joint repositioning error sense. Additionally, it was determined that there was fair relationship between the daily calling time on smartphone and potential neck pain and disability. CONCLUSIONS: The prolonged calling duration on smartphone could affect cervical joint repositioning error sense in university students. This might be related to potential discomfort on cervical region in the further period.
