Ultrasound Diagnostic and Physiotherapy Approach for a Patient with Parsonage-Turner Syndrome-A Case Report.

Parsonage-Turner syndrome (PTS) is a rare neurological disorder that causes major diagnostic problems. This paper presents a case report of a patient with PTS and proposes a new physiotherapy program. CASE DESCRIPTION: a 23-year-old man presents a sudden severe pain of his right arm. The man is consulted by several doctors and physiotherapists. Three magnetic resonance imagings (MRI), a nerve conduction study (NCS), and needle electromyography (EMG) are performed. After 6 months, based on medical history, physical examination and ultrasound imaging (UI), the physiotherapist suggests PTS, which is confirmed by a neurologist. INTERVENTION: due to the lack of physiotherapy treatment standards in PTS, we apply neurodynamic techniques. OUTCOMES: neurodynamic techniques are effective in reducing pain and paraesthesia, improving sensation, and reducing nerve swelling (assessed by UI), as well as improving manual dexterity and overall health status. CONCLUSIONS: the patient with PTS is challenging for making an accurate diagnosis. This study shows an important role for UI, which shows changes in the musculocutaneous nerve, despite the lack of abnormalities in the MRI, NCS, and EMG, and helps in making an accurate diagnosis. This report also confirms that physiotherapy based on neurodynamic techniques may have beneficial effects in PTS.

Ultrasonography in Assessment of Respiratory Muscles Function: A Systematic Review.

INTRODUCTION: The purpose of this study was to evaluate the potential utility of respiratory muscles ultrasound (US) imaging for assessing respiratory function and identify US variables that best correlate with pulmonary parameters. MATERIALS AND METHODS: A search of 5 databases was conducted. Initially, there was no language, study design, or time frame restrictions. All studies assessing the relationship between pulmonary and US parameters were included. Two reviewers independently extracted and documented data regarding to examined population, age, gender, health condition, methodology, US, and pulmonary function measurements. All studies were qualitative synthesis. RESULTS: A total of 1,272 participants from 31 studies were included. Diaphragm thickness, diaphragm thickening ratio, and diaphragm excursion amplitude were mainly used as US parameters. Forced vital capacity, forced expiratory volume1sec, and maximal inspiratory pressure were mainly used as pulmonary parameters. The relationships between pulmonary and US parameters varied from negligible to strong (depend on examined population and methodology used). Data were not quantitatively synthesis due to high heterogeneity in terms of study design, population examined, and various pulmonary and US parameters. CONCLUSION: A strong relationship between US measurements and pulmonary parameters was demonstrated in some studies but not others. This review confirmed that US measurements can complement spirometry, but the exact role of the US remains to be confirmed. Further studies using standardized methodology are needed to obtain more conclusive evidence on the usefulness of US for assessing respiratory function.

Intra-Rater Reliability of Shear Wave Elastography for the Quantification of Respiratory Muscles in Adolescent Athletes.

The aim of this study was to assess the intra-rater reliability and agreement of diaphragm and intercostal muscle elasticity and thickness during tidal breathing. The diaphragm and intercostal muscle parameters were measured using shear wave elastography in adolescent athletes. To calculate intra-rater reliability, intraclass correlation coefficient (ICC) and Bland-Altman statistics were used. The reliability/agreement for one-day both muscle measurements (regardless of probe orientation) were at least moderate. During the seven-day interval between measurements, the reliability of a single measurement depended on the measured parameter, transducer orientation, respiratory phase, and muscle. Excellent reliability was found for diaphragm shear modulus at the peak of tidal expiration in transverse probe position (ICC3.1 = 0.91-0.96; ICC3.2 = 0.95), and from poor to excellent reliability for the intercostal muscle thickness at the peak of tidal inspiration with the longitudinal probe position (ICC3.1 = 0.26-0.95; ICC3.2 = 0.15). The overall reliability/agreement of the analysed data was higher for the diaphragm measurements (than the intercostal muscles) regardless of the respiratory phase and probe position. It is difficult to identify a more appropriate probe position to examine these muscles. The shear modulus/thickness of the diaphragm and intercostal muscles demonstrated good reliability/agreement so this appears to be a promising technique for their examination in athletes.

Changes in Ultrasound Measurements of the Ulnar Nerve at Different Elbow Joint Positions in Patients with Cubital Tunnel Syndrome.

Ultrasound imaging (US) is increasingly being used in the diagnosis of entrapment neuropathies. The aim of the current study was to evaluate changes in stiffness (shear modulus), cross-sectional area (CSA), and trace length (TRACE) of the ulnar nerve in patients with cubital tunnel syndrome (CuTS), with shear wave elastography (SWE). A total of 31 patients with CuTS were included. CSA, shear modulus, and TRACE examinations were performed in the SWE mode in four positions of the elbow: full extension, 45° flexion, 90° flexion, and maximum flexion. There were significant side-to-side differences in the ulnar nerve elasticity value at 45°, 90°, and maximal elbow flexion (all, p < 0.001) but not at elbow extension (p = 0.36). There were significant side-to-side differences in the ulnar nerve CSA value at each elbow position (all, p < 0.001). There were significant side-to-side differences in the ulnar nerve trace value at each elbow position (all, p < 0.001). The symptomatic ulnar nerve in patients with CuTS exhibited greater stiffness (shear modulus), CSA, and TRACE values, compared with the asymptomatic side. US examinations (shear modulus, CSA, and TRACE evaluation) of the ulnar nerve can be helpful in supporting and supplementing the diagnosis in patients with CuTS.

Lateral Abdominal Muscles Shear Modulus and Thickness Measurements under Controlled Ultrasound Probe Compression by External Force Sensor: A Comparison and Reliability Study.

The aim of this study was to perform a reliability and agreement analysis and to compare lateral abdominal muscles (LAMs) thickness and elasticity results obtained by an experienced operator, by a non-experienced operator, and in an ultrasound imaging probe compression controlled (PCC) condition with minimal force necessary to obtain a proper ultrasound image. The sample consisted of 39 adolescents. An Aixplorer ultrasound scanner was used to evaluate the LAM. The probe in PCC condition was positioned in a prepared probe holder coupled with a pressure sensor. The LAM thickness and elasticity measurements were significantly (p < 0.05) different in the ultrasound PCC condition, compared to results obtained by both examiners. The abdominal oblique external and internal muscle thickness measurements were underestimated and all LAM shear moduli were overestimated during measurements without controlling the probe compression by an external sensor. The intra-class correlation coefficient was excellent in all conditions, but the smallest detectable differences were approximately 43-60% lower during the measurements collected in PCC condition. Differences in LAM measurements between PCC and 'on-hand' conditions may be clinically irrelevant when the force applied by the probe is consciously controlled by the examiner. However, during ultrasound measurements of the LAM morphology, the potential under/over estimation should always be considered when measurements are performed without controlling probe compression by an external sensor.

Intrarater Reliability of Shear Wave Elastography for the Quantification of Lateral Abdominal Muscle Elasticity in Idiopathic Scoliosis Patients.

OBJECTIVE: To date, studies evaluating the reliability of shear wave elastography (SWE) measures of the lateral abdominal muscles (LAMs) in adolescent patients with idiopathic scoliosis (AIS) have never been performed. The aim of the study was to assess the intrarater reliability of SWE and thickness of the LAMs at rest and during isometric contraction (10% of maximal voluntary contraction). METHODS: This was a single-group, repeated-measures intrarater reliability study. Twenty-four patients with AIS between ages 10 and 17 years took part in the study. Two and 3 repeated SWE measurements were recorded in the supine resting position and during isometric contraction, respectively. Two sessions were performed with a 7-day interval. RESULTS: By using the mean of 2 measures in the supine, resting position, intraexaminer reliability point estimates (intraclass correlation coefficient [ICC]3.2) ranged from 0.75 to 0.84 for external oblique, internal oblique, and transversus abdominis muscles. During the isometric contraction, the ICC3.3 results ranged from 0.70 to 0.83. The ICC results for muscle thicknesses in both conditions ranged from 0.89 to 0.96. CONCLUSION: Measurements of LAM elasticity are reliable in patients with AIS. The superficial fat layer did not influence the measurement error between 2 sets of measurements in the examined adolescent population. The images extracted from SWE can successfully be used to assess LAM thicknesses with high reliability.

Is manual therapy based on neurodynamic techniques effective in the treatment of carpal tunnel syndrome? A randomized controlled trial.

OBJECTIVE:: The aim of this study was to evaluate the efficacy of manual therapy based on neurodynamic techniques in conservative treatment of carpal tunnel syndrome. DESIGN:: Randomized controlled trial. SETTING:: Several medical outpatient clinics in the south of Poland. PARTICIPANTS:: The study included 103 patients with mild and moderate carpal tunnel syndrome (mean age = 53.95, SD = 9.5) years, who were randomly assigned to a neurodynamic techniques group (experimental group, n = 58) or a group without treatment (control group, n = 45). INTERVENTION:: Neurodynamic techniques were used in the experimental group. Treatment was conducted twice weekly (20 sessions). Control group did not receive treatment. MAIN MEASURES:: Nerve conduction study, pain, symptom severity and functional status of Boston Carpal Tunnel Questionnaire, and strength of cylindrical and pincer grips were assessed at baseline and immediately after treatment (nerve conduction study one month after treatment). RESULTS:: Baseline assessment revealed no group differences in any assessed parameters ( P > 0.05). There were significant differences between groups after treatment, including nerve conduction (e.g. sensory conduction velocity: experimental group: 38.3 m/s, SD = 11.1 vs control group: 25.9 m/s, SD = 7.72, P < 0.01). Significant changes also occurred in pain (experimental group: 1.38, SD = 1.01 vs control group: 5.46, SD = 1.05, P < 0.01), symptom severity (experimental group: 1.08, SD = 0.46 vs control group: 2.87, SD = 0.68, P < 0.01), and functional status (experimental group: 1.96, SD = 0.64 vs control group: 2.87, SD = 1.12, P < 0.01). There were no group differences in strength ( P > 0.05). CONCLUSION:: The use of neurodynamic techniques in conservative treatment for mild to moderate forms of carpal tunnel syndrome has significant therapeutic benefits.

Neurodynamic Techniques Versus "Sham" Therapy in the Treatment of Carpal Tunnel Syndrome: A Randomized Placebo-Controlled Trial.

OBJECTIVE: To evaluate the efficacy of neurodynamic techniques used as the sole therapeutic component compared with sham therapy in the treatment of mild and moderate carpal tunnel syndromes (CTS). DESIGN: Single-blinded, randomized placebo-controlled trial. SETTING: Several medical clinics. PARTICIPANTS: Volunteer sample of patients (N=250) diagnosed with CTS (n=150). INTERVENTIONS: Neurodynamic techniques were used in the neurodynamic techniques group, and sham therapy was used in the sham therapy group. In the neurodynamic techniques group, neurodynamic sequences were used, and sliding and tension techniques were also used. In the sham therapy group, no neurodynamic sequences were used, and therapeutic procedures were performed in an intermediate position. Therapy was conducted twice weekly for a total of 20 therapy sessions. MAIN OUTCOME MEASURES: Symptom severity (symptom severity scale) and functional status (functional status scale) of the Boston Carpal Tunnel Questionnaire. RESULTS: A baseline assessment revealed no intergroup differences in all examined parameters (P>.05). After therapy, there was statistically significant intragroup improvement in nerve conduction study (sensory and motor conduction velocity and motor latency) only for the neurodynamic techniques group (P<.01). After therapy, intragroup statistically significant changes also occurred for the neurodynamic techniques group in pain assessment, 2-point discrimination sense, symptom severity scale, and functional status scale (in all cases P<.01). There were no group differences in assessment of grip and pinch strength (P>.05). CONCLUSIONS: The use of neurodynamic techniques has a better therapeutic effect than sham therapy in the treatment of mild and moderate forms of CTS.

Back School programme for nurses has reduced low back pain levels: A randomised controlled trial.

AIMS AND OBJECTIVES: (i) To examine patient lifting techniques used by nurses, and (ii) to evaluate an effectiveness of the Spine Care for Nurses programme in chronic nonspecific low back pain syndrome reduction and the execution of proper patient lifting techniques. BACKGROUND: Millions of nurses around the world suffer from occupational-related chronic nonspecific low back pain (chronic nonspecific low back pain syndrome). Generally, low back pain in nurses is a result of increased pressure on the spine and can be associated with improperly conducted patient lifting techniques. METHODS: A randomised controlled trial was conducted among 137 nurses with chronic nonspecific low back pain syndrome. Participants were randomised into an experimental and control group (experimental group n = 67, control group n = 70). Nurses in the experimental group attended the Spine Care for Nurses programme for 3 months. The programme consisted of didactic education, spine-strengthening exercises and education on safe patient handling techniques. The control group only received a brief written lifestyle guidance. The Zebris WinSpine Triple Lumbar examination was used to analyse nurses' patient lifting techniques (horizontal and vertical lifting). The lumbar pain intensity was measured with a 0-100 visual analogue scale. RESULTS: The pre-intervention average chronic nonspecific low back pain syndrome intensity score on visual analogue scale decreased from 49.3 to the postintervention score of 7.5. The correct execution of vertical lifting techniques in the experimental group increased from 8.91%-97.01% (control group: 8.57% pre-intervention test and postintervention test 11.42%). The horizontal patient lifting technique pre-intervention increased from 10.44%-100% correct execution in the experimental group (control group: pre-intervention test 10.00% and postintervention test 11.42%). CONCLUSION: The Spine Care for Nurses programme significantly reduced chronic nonspecific low back pain syndrome and increased the number of properly executed horizontal and vertical patient lifting techniques in nurses. RELEVANCE TO CLINICAL PRACTICE: We recommend that healthcare organisations should consider the implementation of regular Spine Care for Nurses programmes as successful low back injury prevention programmes.

The Effect of Manual Therapy Including Neurodynamic Techniques on the Overall Health Status of People With Carpal Tunnel Syndrome: A Randomized Controlled Trial.

OBJECTIVE: The purpose of this study was to assess the influence of manual therapy, including neurodynamic techniques, compared with no treatment on overall health status (OHS) in patients with mild to moderate carpal tunnel syndrome (CTS). METHODS: The study included 189 patients with CTS who were randomly assigned to the manual therapy (MT) group (including the use of neurodynamic techniques) or to the control group (CG; without therapy). The CTS diagnosis was made on the basis of nerve conduction studies and clinical examinations. Overall health status was assessed using the RAND 36-Item Short Form Health Survey. Therapy in the MT group was conducted twice weekly (20 therapy sessions). The CG had no therapy. RESULTS: A baseline assessment revealed no group differences in the physical and mental components of OHS (in all cases P > 0.05).There were also no significant differences in the Physical Component Summary or Mental Component Summary on the RAND 36-Item Short Form Health Survey (P > 0.05). Immediately after therapy, analysis of variance revealed differences in the physical and mental components in the MT group (in all cases P < 0.001) and no differences in the CG (in all cases P > 0.05). After therapy, analysis of variance also revealed differences in Physical Component Summary and Mental Component Summary in the MT group (in both cases P < 0.001) and no differences in the CG (in both cases P > 0.05). CONCLUSION: Manual therapy, including neurodynamic techniques, had a positive effect on OHS in this group of individuals with CTS.

Body Mass Normalization for Lateral Abdominal Muscle Thickness Measurements in Adolescent Athletes.

OBJECTIVES: To determine the value of allometric parameters for ultrasound measurements of the oblique external (OE), oblique internal (OI), and transversus abdominis (TrA) muscles in adolescent athletes. The allometric parameter is the slope of the linear regression line between the log-transformed body mass and log-transformed muscle size measurement. METHODS: The study included 114 male adolescent football players between the ages of 10 and 19 years. All individuals with no surgical procedures performed on the trunk area and who had played a sport for at least 2 years were included. A real-time B-mode ultrasound scanner with a linear array transducer was used to obtain images of the lateral abdominal muscles from both sides of the body. A stabilometric platform was used to assess the body mass value. RESULTS: The correlations between body mass and the OE, OI, and TrA muscle thicknesses were r = 0.73, r = 0.79, and r = 0.64, respectively (in all cases, P < .0001). The allometric parameters were 0.77 for the OE, 0.67 for the OI, and 0.61 for the TrA. Using these parameters, no significant correlations were found between body mass and the allometric-scaled thickness of the lateral abdominal muscles. CONCLUSIONS: Significant positive correlations exist between body mass and lateral abdominal muscle thickness in adolescent athletes. Therefore, it is reasonable to advise that the values of the allometric parameters for the OE, OI, and TrA muscles obtained in this study should be used, and the allometric-scaled thicknesses of those muscles should be analyzed in future research on adolescent athletes.

Body Mass Normalization for Ultrasound Measurements of Adolescent Lateral Abdominal Muscle Thickness.

OBJECTIVES: The purpose of this study was to determine the value of the allometric parameter for ultrasound measurements of the thickness of the oblique external (OE), internal (OI), and transversus abdominis (TrA) muscles in the adolescent population. The allometric parameter is the slope of the linear regression line between the log transformed body mass and log transformed muscle size measurement. METHODS: The study included 321 adolescents between the ages of 10 and 17, consisting of 160 boys and 161 girls. The participants were recruited from local schools and attended regular school classes at normal grade levels. All individuals with no signs of scoliosis (screening with use of a scoliometer), and no surgical procedures performed on the trunk area were included. A real-time ultrasound B-scanner with a linear array transducer was used to obtain images of the lateral abdominal muscles from both sides of the body. RESULTS: The correlation between body mass and the OE muscle was r = 0.69; the OI muscle r = 0.68; and the TrA muscle r = 0.53 (in all cases, P < .0001). The allometric parameter for the OE was 0.88296; the OI 0.718756; and the TrA 0.60986. Using these parameters, no significant correlations were found between body mass and the allometric-scaled thickness of the lateral abdominal muscles. CONCLUSIONS: Significant positive correlations exist between body mass and lateral abdominal muscle thickness assessed by ultrasound imaging. Therefore, it is reasonable to advise that the values of the allometric parameters for OE, OI, and TrA obtained in this study should be used in other studies performed on adolescents.

Overall health status in patients with mild to moderate carpal tunnel syndrome: A case-control study.

STUDY DESIGN: A case-control study. INTRODUCTION: There are no reports in the literature that evaluate the overall health status (OHS) of patients with mild to moderate forms of carpal tunnel syndrome (CTS) using 36-Item Short Form Health Survey (SF-36). PURPOSE OF THE STUDY: To assess OHS in patients with mild to moderate CTS, in comparison with healthy subjects. METHODS: The study involved 273 healthy people and 140 people diagnosed with CTS. The CTS diagnosis was made on the basis of clinical examinations and nerve conduction studies. OHS was assessed using the SF-36. RESULTS: In the assessment of physical components of OHS, in the CTS group (compared with healthy subjects), the results show significantly lower values in physical functioning, role limitations because of physical health problems, bodily pain, and general health perceptions by 7.44, 23.2, 18.9, and 4.1, respectively. Mental components were lower (in CTS group) only in relation to vitality and social functioning by 4.1 and 5.5, respectively. In the assessment of physical component summary (PCS) and mental component summary (MCS), the results show significantly lower values of PCS (by 13 in CTS group) and no significant differences in the assessment of MCS between patients with CTS and healthy subjects. DISCUSSION: The perception of the OHS in CTS patients is diminished. Hence, when evaluating the effects of the therapy, not only disease-specific scales should be used, but also the OHS. This will allow an assessment of the impact of CTS on OHS and the impact of applied therapy, not only in terms of a reduction in the main symptoms of the condition. CONCLUSIONS: Mild and moderate forms of CTS significantly affected the PCS of the OHS and all its subcomponents (physical functioning, role limitations because of physical health problems, bodily pain, and general health perceptions) but did not affect the MCS of OHS evaluated as a whole. There were significant differences in the mental component in the evaluation of vitality and social functioning. LEVEL OF EVIDENCE: 3.

Efficacy of Manual Therapy Including Neurodynamic Techniques for the Treatment of Carpal Tunnel Syndrome: A Randomized Controlled Trial.

OBJECTIVE: The purpose of this randomized trial was to compare the efficacy of manual therapy, including the use of neurodynamic techniques, with electrophysical modalities on patients with mild and moderate carpal tunnel syndrome (CTS). METHODS: The study included 140 CTS patients who were randomly assigned to the manual therapy (MT) group, which included the use of neurodynamic techniques, functional massage, and carpal bone mobilizations techniques, or to the electrophysical modalities (EM) group, which included laser and ultrasound therapy. Nerve conduction, pain severity, symptom severity, and functional status measured by the Boston Carpal Tunnel Questionnaire were assessed before and after treatment. Therapy was conducted twice weekly and both groups received 20 therapy sessions. RESULTS: A baseline assessment revealed group differences in sensory conduction of the median nerve (P < .01) but not in motor conduction (P = .82). Four weeks after the last treatment procedure, nerve conduction was examined again. In the MT group, median nerve sensory conduction velocity increased by 34% and motor conduction velocity by 6% (in both cases, P < .01). There was no change in median nerve sensory and motor conduction velocities in the EM. Distal motor latency was decreased (P < .01) in both groups. A baseline assessment revealed no group differences in pain severity, symptom severity, or functional status. Immediately after therapy, analysis of variance revealed group differences in pain severity (P < .01), with a reduction in pain in both groups (MT: 290%, P < .01; EM: 47%, P < .01). There were group differences in symptom severity (P < .01) and function (P < .01) on the Boston Carpal Tunnel Questionnaire. Both groups had an improvement in functional status (MT: 47%, P < .01; EM: 9%, P < .01) and a reduction in subjective CTS symptoms (MT: 67%, P < .01; EM: 15%, P < .01). CONCLUSION: Both therapies had a positive effect on nerve conduction, pain reduction, functional status, and subjective symptoms in individuals with CTS. However, the results regarding pain reduction, subjective symptoms, and functional status were better in the MT group.

Effect of manual therapy and neurodynamic techniques vs ultrasound and laser on 2PD in patients with CTS: A randomized controlled trial.

STUDY DESIGN: Randomized controlled trial. INTRODUCTION: Two-point discrimination (2PD) test can be used to assess both clinical condition and the effects of therapy in carpal tunnel syndrome (CTS) patients. PURPOSE OF THE STUDY: To determine whether there are specific differences in 2PD between symptomatic and asymptomatic hands in CTS patients and to evaluate the impact of 2 therapy regimes on 2PD in patients with CTS. METHODS: Therapy for the neurodynamic mobilization group was based on manual therapy and neurodynamic techniques. Therapy for the electrophysical modalities group was based on red and infrared laser and ultrasound therapy using a contact method applied in the transverse ligament area. Therapeutic cycle consisted of 20 therapy sessions delivered at twice-weekly intervals. RESULTS: After therapy, 2PD in the symptomatic limbs in the neurodynamic mobilization and electrophysical modalities groups significantly improved (p < .001). However, there was no statistically significant difference between the treatment groups. CONCLUSIONS: Both therapy programs used in this study were beneficial for improving 2PD. LEVEL OF EVIDENCE: 2.

Impact of physical activity and fitness on the level of kinesiophobia in women of perimenopausal age.

To determine the impact of physical activity and fitness on the level of physical activity barriers (kinesiophobia) in women of perimenopausal age, the study included 105 women between the ages of 48 and 58. A Baecke questionnaire was used to evaluate physical activity and a modified Fullerton test was used to evaluate the fitness level. The level of kinesiophobia was assessed using the Kinesiophobia Causes Scale questionnaire. A low level of habitual physical activity has a negative impact on the values of Biological Domain (r = -0.581), Psychological Domain (r = -0.451), and on the Kinesiophobia Cause Scale total score (r = -0.577). Lower physical activity expressed by a lower score in the Fullerton test also has a negative impact on the level of kinesiophobia. Upper body flexibility (r = -0.434) has the strongest influence on the Biological Domain, whereas upper body strength (r = -0.598) has the greatest impact on the Psychological Domain. A low level of upper body strength also has the greatest impact on the Kinesiophobia Cause Scale total score (r = -0.507). Low levels of physical activity and fitness in women of perimenopausal age favour kinesiophobic attitudes and thereby increase the level of barriers against undertaking physical activity.

Back and neck pain among school teachers in Poland and its correlations with physical activity.

BACKGROUND: Back pain represents one of the most common diseases across various populations of workers worldwide. This study analyzes the prevalence and severity of back pain, based on selected demographic variables, and the relationship with physical activity among school teachers. MATERIAL AND METHODS: The study included 998 professionally active teachers (840 females and 158 males) from the southern part of Poland. Validated psychometric tools, namely: 1) for evaluation of disability due to back pain - a Polish version of the Oswestry Disability Index (ODI) and Neck Disability Index (NDI), 2) for physical activity assessment - the Subjective Experience of Work Load (SEWL) as well as the authors' supplementary questionnaire, addressing demographic and anthropometric variables were used. RESULTS: There was no correlation between age and the NDI scores in females (r = 0.027), in contrast to males (r = 0.202; p ≤ 0.05). Statistically significant correlations (p ≤ 0.05) were reported between: age and the ODI, in both females (r = 0.219) and males (r = 0.180). No associations between the body mass index (BMI)-ODI, and BMI-NDI were found. In the case of women, disability related to low back pain (LBP) had a negative impact on the indicators of their activity during work, sports, and leisure time. In the case of men, the NDI and ODI scores did not differ, based on activity indicators. CONCLUSIONS: Our findings confirm that back pain represents a serious concern among teachers. Age appears to be a prognostic factor, while no association between the BMI and LBP has been revealed. The limitation of physical activity leads to more frequent back pain.

Ultrasound evaluation of the symmetry of abdominal muscles in mild adolescent idiopathic scoliosis.

[Purpose] The objective of the study was to evaluate the symmetry of the thickness of the abdominal muscles at rest and while standing in patients with adolescent idiopathic scoliosis. [Subjects and Methods] An ultrasound assessment was performed of the side-to-side differences of the external oblique (EO), internal oblique (IO), and transversus abdominalis (TrA) muscles in the supine and standing positions in adolescent idiopathic scoliosis (AIS) and control groups. [Results] In the AIS group, 64.3% of the patients had left scoliosis with a mean Cobb angle of 10.7°, and 35.7% of the patients had right scoliosis with a mean Cobb angle of 10°. In the supine position, the thickness asymmetry of the TrA was greater in the AIS compared with the control group by an average of 14% (95% CI 3.9-24.2). [Conclusion] Among the abdominal muscles examined, patients with AIS exhibited more asymmetry only for the TrA. In the standing position, the TrA was as symmetric in the patients as in the control group. Mild scoliosis has no impact on the symmetry of the thickness of the OE and OI in the supine and standing positions. The direction of curvature had no effect on the symmetry of the abdominal muscles studied.

Effect of a 4-week Nordic walking training on the physical fitness and self-assessment of the quality of health of women of the perimenopausal age.

AIM OF THE STUDY: To determine the effect of a 4-week Nordic walking training on the physical fitness of women of the perimenopausal age and self-assessment of the quality of their health. MATERIAL AND METHODS: Eighty-four women between 48 and 58 years of age were included in the study. Half of the group (42) was assigned to the control group and the other half was assigned to the experimental group. In both groups studied, physical fitness was evaluated using a modified Fullerton's test and a quality of life self-assessment SF-36 (Short Form of Health Status Questionnaire). Similar tests were repeated 4 weeks later. In the experimental group, a Nordic walking training was conducted between the two tests. During 4 weeks, 10 training sessions were performed, each session was 60 minutes long, and there was an interval of 2 days between the sessions. RESULTS: A 4-week Nordic walking training resulted in a significant improvement (p < 0.001) of physical fitness as demonstrated by an increased strength and flexibility of the upper and lower part of the body and the ability to walk a longer distance during a 6-minute walking test. Women participating in the training also showed a significant improvement in health in terms of both physical health (p < 0.001) and mental health (p < 0.001). CONCLUSIONS: A 4-week Nordic walking training has a positive effect on the physical fitness of the women in the perimenopausal age. Participation in training contributes also to a clearly higher self-assessment of the quality of health.
