The prolonged effect of Kinesio Taping on joint torque and muscle activity.

PURPOSE: Although Kinesio Taping has been extensively used, evidence about the effect of Kinesio Taping is still insufficient. The aim is to determine the effect of Kinesio Taping on elbow joint torque and muscle activity in time and frequency domains. MATERIALS AND METHODS: Thirty-eight healthy subjects were (27 females and 11 males) randomly divided into control and Kinesio Taping groups. Kinesio Taping was applied over biceps brachii muscle in Kinesio Taping group, whereas no taping was applied to control group. Maximum elbow joint torque and electromyography activity in time and frequency domains were assessed during maximum isometric contraction of biceps brachii muscle at baseline, after 10 min, 30 min, and 24 h. Repeated measure ANOVA and mixed ANOVA tests were used for in-group and between-group comparisons, respectively. RESULTS: Elbow joint torques among four assessment sessions were statistically altered in Kinesio Taping group and greater in Kinesio Taping group than in control group (F(3,57)= 3.317, p = 0.026, ηp2 = 0.149; F(3,108)=3.325, p = 0.022, ηp2 = 0.085; respectively). No difference was found in time domain muscle activity among assessment sessions in each group and comparison of groups (p > 0.05). Low-gamma band activity was changed among assessment sessions in Kinesio Taping group (F(3,57)= 6.946, p < 0.001, ηp2 = 0.268) while group × time interaction was not determined. CONCLUSIONS: Kinesio Taping may influence joint torque of elbow more than without Kinesio Taping condition in 24th hour but the interpretation of this effect as a muscle strength enhancement compared with baseline can be arguable. Even if Kinesio Taping could not affect muscle activity in time domain, low-gamma band activity which is closely related to somatosensorial input may reach highest magnitude 24 h after Kinesio Taping.

Does the effect of comprehensive respiratory physiotherapy home-program differ in children with cystic fibrosis and non-cystic fibrosis bronchiectasis?

Bronchiectasis is a form of airway damage as a consequence of endobronchial infection and inflammation and may be present in different diseases. The underlying aetiologies include both cystic fibrosis (CF) and a group of non-cystic fibrosis diseases (NCFB) such as immunodeficiency, primary ciliary dyskinesia, or severe pulmonary infection. Although children with CF and non-cystic fibrosis bronchiectasis (NCFB) have many similar clinical features, their responses to exercise may be different. The aim of this study was to compare the efficacy of a comprehensive respiratory physiotherapy (CRP) home-program in children with CF and NCFB. Thirty children with CF and thirty children with NCFB were included in the study. Both groups performed the CRP home-program twice daily for 8 weeks. Pulmonary function, exercise capacity, and respiratory and peripheral muscle strength were assessed at baseline and after 8 weeks of training. Both groups experienced significant improvements in pulmonary function, exercise capacity, and respiratory and peripheral muscle strength (p < 0.001). Maximum expiratory pressure, exercise capacity, and peripheral muscle strength were further improved in NCFB group compared to CF (p < 0.05); however, there was a great variability in the improvements for each variable. CONCLUSION: CRP is beneficial both for children with CF and NCFB and adherence to the program was high in both groups. WHAT IS KNOWN: • Different physiotherapy approaches in the management of non-cystic fibrosis bronchiectasis have been based on the experience gained from the research studies performed in cystic fibrosis. • Although having similar pathophysiology, these two diseases show variation in some pulmonary and extrapulmonary features. WHAT IS NEW: • The respiratory muscle strength and the efficacy of comprehensive respiratory physiotherapy have been compared for the first time in children with cystic fibrosis and non-cystic fibrosis bronchiectasis. • Comprehensive respiratory physiotherapy provides higher increases in children with non-cystic fibrosis bronchiectasis in exercise capacity and expiratory and peripheral muscle strength; however, there was a great variability in these improvements. Nevertheless, it can be concluded that both groups significantly benefited from the CRP program.

The effect of proprioceptive neuromuscular facilitation on individuals with text neck syndrome: A randomized controlled study.

BACKGROUND: Text neck syndrome is an overuse condition that has become a global problem for all ages who use smartphones. Although therapeutic approaches are used to manage text neck syndrome, relatively little evidence exists on efficacy. This study aimed to investigate the effects of proprioceptive neuromuscular facilitation (PNF) techniques on individuals with text neck syndrome. METHODS: Thirty-eight participants with text neck syndrome were randomly allocated to either the experimental or control group. Both groups performed the program including cervical range of motion, strengthening, and posture correction exercises for 6 weeks, 3 days a week, once a day for 10 repetitions. In the experimental group were included in a PNF program 3 days a week for 6 weeks. In the program, contract-relax and replication techniques were used. Pain intensity, cervical range of motion, cervical muscles' endurance, posture, and disability were assessed. Outcome measures were assessed at baseline and after 6 weeks. RESULTS: Pain intensity, neck muscle endurance tests, posture, and disability scores significantly improved in both groups (P < .05). The cervical range of motion values in all directions were significantly increased only in the experimental group (P < .05). The improvements in pain intensity, neck muscle endurance tests, posture, and disability scores were greater in the experimental group compared with the control group (P < .05). CONCLUSION: PNF could be used effectively to reduce neck pain and disability level and enhance cervical range of motion, cervical muscles' endurance, and posture in individuals with text neck syndrome.

Exploring Balance Impairment and Determinants in Chronic Obstructive Pulmonary Disease: A Comparative Study with Healthy Subjects.

Background: Many pulmonary and extrapulmonary factors may impair balance in patients with chronic obstructive pulmonary disease (COPD), but the determinants of this impairment are still debated. The primary aim was to compare both balance-related and independent variables that may affect balance with healthy subjects. The secondary aim was to investigate the potential determinants of balance in patients with COPD. Methods: This comparative study recruited 23 patients with COPD and 23 age- and comorbidity-matched healthy subjects. Participants were assessed regarding demographic and clinical data, "Postural Stability Test" (PST), "Limits of Stability Test" (LOST), "Clinical Test of Sensory Integration of Balance" (CTSIB), pulmonary function, respiratory and peripheral muscle strength, functional capacity, and cognitive function. Results: There were significant differences in all outcome measures assessing balance, pulmonary function, respiratory muscle strength, peripheral muscle strength, and functional capacity, but not cognitive function, in the COPD group compared to the healthy group (p < 0.05). The PST had a significant and strong correlation with maximal inspiratory pressure (MIP) (r = -0.630, p = 0.001) and a significant and moderate correlation with m. quadriceps strength and 6 min walk test (6MWT) distance (r = -0.472, p = 0.023; r = -0.496, p = 0.016; respectively). MIP, m. quadriceps strength, and 6MWT distance were independent predictors to explain the PST with an R2 = 0.336 (p = 0.004). Conclusions: The present study revealed that balance is impaired in adults with COPD, even if compared with age- and comorbidity-matched healthy subjects. Assessing and improving balance and its determinants, inspiratory and peripheral muscle strength, and functional capacity may be important for fall prevention and disease management in patients with COPD.

Relationship between inter-recti distance, abdominal muscle endurance, pelvic floor functions, respiratory muscle strength, and postural control in women with diastasis recti abdominis.

OBJECTIVE: The main objective was to assess the relationship between inter-recti distance (IRD) and abdominal muscle endurance, pelvic floor functions, respiratory muscle strength, and postural control in women with Diastasis Recti Abdominis (DRA). Additionally, the secondary purpose of the study is to investigate the independent predictors of IRD in women with DRA. STUDY DESIGN: Fifty-one women who were diagnosed with DRA participated to the study. IRD assessment with a caliper, abdominal muscle endurance test, Pelvic Floor Distress Inventory Questionnaire-20 (PFDI-20), maximum inspiratory and expiratory pressure (MIP and MEP, respectively) tests, Clinical Test of Sensory Integration of Balance (m-CTSIB) under eyes open on a firm surface (EOFS), eyes closed on a firm surface (ECFS), eyes open on a foam surface (EOFoS), and eyes closed on a foam surface (ECFoS) conditions, and Limits of Stability (LOS) tests were performed for all subjects. Pearson or Spearman correlation analyses were used to determine the relationship between IRD and static abdominal flexion endurance test, PFDI-20, MIP and MEP, m-CTSIB, and LOS scores depending on the distribution properties of the data. Additionally, linear regression analysis was utilized for analyzing the independent predictors of IRD among the age, BMI, parity, time since last birth, birth weight, weight gains last pregnancy, and mode of delivery. RESULTS: IRD had correlations with Colorectal-Anal Distress score of PFDI-20 (r = -0.317, p = 0.03) and EOFS, ECFS, EOFoS, ECFoS and composite score of m-CTSIB (r = 0.356, p = 0.01; r = 0.337, p = 0.02, r = 0.279, p = 0.04; r = 0.265, p = 0.04; r = 0.413, p = 0.004, respectively) and LOS scores (r = 0.422, p = 0.003). Increased IRD did not influence abdominal muscle endurance and respiratory muscle strength in women with DRA (p < 0.05). Age, BMI, time since last birth, weight gains last pregnancy, and mode of delivery were not determined as the factors that influence IRD in women with DRA (p < 0.05). CONCLUSION: We concluded that increased IRD is associated with worse postural control, but better colorectal functions in women with DRA. Additionally, IRD does not show a clear association with abdominal muscle endurance, pelvic floor functions, and respiratory muscle strength. According to our results, postural stability assessments may perform in the physiotherapeutic management of women with DRA.

Sit-to-stand test in children with bronchiectasis: Does it measure functional exercise capacity?

BACKGROUND: Similar to six-minute walk test (6MWT), sit-to-stand test (STST) is a self-paced test which elicits sub-maximal effort; therefore, it is suggested as an alternative measurement for functional exercise capacity in various pulmonary conditions including COPD and cystic fibrosis. We aimed to investigate the association between 30-second STST (30s-STST) and 6MWT in both children with bronchiectasis (BE) and their healthy counterparts, as well as exploring cardiorespiratory burden and discriminative properties of both tests. METHODS: Sixty children (6 to 18-year-old) diagnosed with non-cystic fibrosis BE and 20 age-matched healthy controls were included. Both groups performed 30s-STST and 6MWT. Test results, and heart rate, SpO2 and dyspnea responses to tests were recorded. RESULTS: Univariate analysis revealed that 30s-STST was able to explain 52% of variance in 6MWT (r = 0.718, p<0.001) in BE group, whereas 20% of variance in healthy controls (r = 0.453, p = 0.045). 6MWT elicited higher changes in heart rate and dyspnea level compared to 30s-STST, indicating it was more physically demanding. Both 30s-STST (21.65±5.28 vs 26.55±3.56 repetitions) and 6MWT (538±85 vs 596±54 m) were significantly lower in BE group compared to healthy controls (p<0.01). Receiver operating characteristic (ROC) curve analysis revealed an area under the ROC curve (UAC) of 0.765 for 30s-STST and 0.693 for 6MWT in identifying the individuals with or without BE (p<0.05). Comparison between AUCs of 30s-STST and 6MWT yielded no significant difference (p = 0.466), indicating both tests had similar discriminative properties. CONCLUSIONS: 30s-STST is found to be a valid alternative measurement for functional exercise capacity in children with BE.

Do pulmonary and extrapulmonary features differ among cystic fibrosis, primary ciliary dyskinesia, and healthy children?

BACKGROUND: Primary ciliary dyskinesia (PCD) is generally likened to cystic fibrosis (CF) due to similarities in impaired mucociliary clearance and some other symptoms. The aim of our study was to investigate pulmonary and extrapulmonary characteristics of children with CF and PCD since no studies have addressed respiratory muscle strength in children with PCD and to compare the results to those obtained from healthy age-matched controls. METHODS: Pulmonary and extrapulmonary characteristics were assessed by 6-min walk test, spirometry, maximum inspiratory and expiratory pressure measurements, and knee extensor strength test in the children with CF, PCD, and healthy controls. RESULTS: Children with PCD and CF had similar PFT results, except forced expiratory flow between 25% and 75% of vital capacity (FEF25-75 ) which was lower in PCD (p = .04). Maximum inspiratory pressure (MIP) value was lower in the children with CF compared with the healthy controls (p = .016), MEP value of the children with PCD was worse than those with CF and healthy controls (p = .013 and p = .013), respectively. 6-min walk test (6MWT) distance of the children with CF was lower than their healthy counterparts (p = .003). Knee extensor muscle strength differed among the children with PCD, CF, and healthy control groups, but post hoc test failed to show statistical significance (p = .010). CONCLUSION: Children with CF and PCD had some impairments in pulmonary functions, respiratory muscle strength, functional capacity, and peripheral muscle strength compared with healthy children. However, the unique characteristics of each disease should be considered during physiotherapy assessment and treatment. The clinicians may especially focus on the respiratory and peripheral muscle strength of the children with PCD.

Influence of quadriceps angle on static and dynamic balance in young adults.

BACKGROUND: Changes in postural stability may be a reason for injuries in individuals who have altered musculoskeletal alignment. Q angle (QA) has shown to be a predictor for lower extremity injuries. However, the relationship between balance and QA has not been investigated in young adults. OBJECTIVE: The aim of the study was to investigate the relationship between QA and balance in young adults. METHODS: Ninety participants performed the single leg stance test (SLST) and Star Excursion Balance Test (SEBT) to assess static and dynamic balance, respectively. QA was measured using a manual goniometer. Participants were divided into low, normal and high QA groups. RESULTS: The relationship between SLST and QA was not statistically significant in both eyes opened and closed condition (r=-0.030, p= 0.782; r= 0.031, p= 0.774; respectively). SLST scores did not differ among the three groups in both eyes opened and closed condition (p= 0.781, p= 0.790; respectively). QA significantly correlated with lateral, posterolateral directions and sum score of SEBT (r= 0.240, p= 0.023; r= 0.269, p= 0.010; r= 0.210, p= 0.047). The comparisons among the low, normal and high Q angle groups' SEBT scores showed that balance performance in lateral direction was poorer in low QA group (p= 0.027). CONCLUSIONS: The results of the study showed that QA and dynamic balance have a significant relationship. To reduce musculoskeletal injury risk, the dynamic balance should be assessed in young adults who have lower QA.

Force irradiation effect of kinesiotaping on contralateral muscle activation.

We aimed to determine the force irradiation effect of kinesiotaping (KT) on contralateral muscle activity during unilateral muscle contraction. Forty healthy (26 females, 14 males) subjects were divided into two groups: KT and control groups. KT was applied on the biceps brachii at the contralateral limb (non-dominant limb) in the KT group, whereas no taping was applied to the control group. All participants performed unilateral isometric, concentric, and eccentric contractions with their dominant upper limbs (exercised limb) by means of an isokinetic dynamometer, while the contralateral limb was in the resting condition, neutral position, and motionless during the testing procedure. During the exercise, contralateral biceps brachii muscle activity was recorded by surface electromyography (EMG). To quantify the muscle activation, EMG signals were expressed as a percentage of the maximal isometric voluntary contraction, which is referred to as %EMGmax. The KT group showed significantly higher %EMGmax in the biceps brachii compared to the control group at the contralateral limb during the isometric, concentric, and eccentric contractions (p = 0.035, p = 0.046, and p = 0.002, respectively) The median values of the contralateral muscle activity were 2.74 %EMGmax and 6.62 %EMGmax during the isometric contraction for the control and KT groups, respectively (p = 0.035). During the concentric contraction, the median values of the contralateral muscle activity were 1.61 %EMGmax and 9.39 %EMGmax for the control and KT groups, respectively (p = 0.046). The median values of the contralateral muscle activity were 4.49 %EMGmax and 22.89 %EMGmax for the eccentric contraction for the control and KT groups, respectively (p = 0.002). In conclusion, KT application on the contralateral limb increased the contralateral muscle activation in the biceps brachii during the unilateral isometric, concentric, and eccentric contractions.

The relationship of sit-to-stand tests with 6-minute walk test in healthy young adults.

The aim of this study was to evaluate the timed sit-to-stand (STS) test performances of healthy young adults and to investigate the relationship of timed STS tests with 6-minute walk test (6MWT). A cross-sectional study was performed. A total of 40 healthy volunteers (mean age: 21.7 ±â€Š1.2 years) were evaluated with 10, 30, and 60 seconds STS tests and 6MWT. Fatigue and shortness of breath were rated using Borg category-ratio scale (CR10) before and after each test. Weekly energy expenditures of volunteers were calculated using International Physical Activity Questionnaire. 30 and 60 seconds STS tests were moderately (r = 0.611 and r = 0.647, respectively) (P < .001) and 10 seconds STS test was weakly (r = 0.344) (P = .028) correlated with 6MWT. Among correlations of each STS test with 6MWT, none of them was statistically stronger to one another (P > .05). Borg fatigue scores after 10, 30, and 60 seconds STS tests were weakly correlated with fatigue score after 6MWT (r = 0.321, r = 0.378, and r = 0.405, respectively) (P < .05). Weekly energy expenditure (MET-min/week) was moderately correlated with 10, 30, and 60 seconds STS tests and 6MWT (r = 0.533, r = 0.598, r = 0.598, and r = 0.547, respectively) (P < .001). Considering the statistically significant relationship between timed STS tests and 6MWT, any of the timed STS tests may be used for a quick and alternative measurement of physical performance and functional capacity in healthy young adults.
