RESUMEN
INTRODUCTION: Subacromial pain syndrome (SPS) is a common cause of shoulder pain, and is associated with functional limitation, workdays lost, disability, and poor quality of life. PURPOSE: Our purpose was to investigate the effects of scapular stabilization exercises in patients with SPS. METHOD: Sixty-four patients with SPS who also exhibit observable scapular dyskinesis defined by the scapular dyskinesis test were recruited and randomized to scapular stabilization exercise training group or to control group. All participants received the same rehabilitation protocol including glenohumeral and scapular mobilization, pendulum exercises, shoulder stretching, range of motion exercises, strengthening, and proprioceptive exercises. Patients in the scapular stabilization exercise training group performed additional scapular stabilization exercises. The presence of scapular dyskinesis, shoulder pain severity, motion, muscle strength, scapular upward rotation, and shoulder disability were assessed before and after the four-week rehabilitation program. RESULTS: The scapular stabilization exercise training group had better improvement in scapular dyskinesis, pain, muscle strength, and shoulder disability compared to the control group (p < 0.05). However, there was no statistically significant time-group interaction regarding shoulder motion and scapular upward rotation (p > 0.05). CONCLUSIONS: Scapular stabilization exercises added to the shoulder mobilization, stretching, and strengthening are effective in improving scapular dyskinesis, reducing pain, increasing muscle strength and shoulder function in patients with SPS accompanied by scapular dyskinesis.

Observable scapular dyskinesis is associated with biomechanical deficits. Preventative interventions aimed at correcting these deficits may aid in preventing the development and resolution of shoulder pain. Our purpose was to investigate the effects of kinesio taping (KT) on common biomechanical deficits associated with scapular dyskinesis and shoulder pain. Participants (n = 51) with observable scapular dyskinesis, and without shoulder pain were randomized to KT, KT-placebo, or a no-treatment control group. Measurements taken before, immediately after taping, and 3 days later included pectoralis minor muscle length, lower trapezius muscle strength, scapular upward rotation angle at 0° to 120° in scapular plane humeral elevation and acromiohumeral distance. There were no changes in scapular upward rotation, lower trapezius strength, and acromiohumeral distance immediately after taping or 3 days later compared to baseline (P > .05). The pectoralis minor increased in length in the KT group on day 3 compared to directly after taping (P = .03), but no difference between groups or interaction between time and group were determined (P > .05). Scapular dyskinesis prevalence did not change over time in any group (P > .05). In people with scapular dyskinesis free from shoulder pain, KT applied to the shoulder cannot be recommended to ameliorate the biomechanical deficits associated with shoulder pain.

BACKGROUND: Step Test (ST) is frequently used to assess dynamic balance and locomotor function in clinical practice. AIMS: This study aimed to determine the concurrent validity, reliability, and minimal detectable change (MDC) of the ST in patients with total knee arthroplasty (TKA). METHODS: The study included 56 patients with TKA. The intraclass correlation coefficient (ICC) was used to assess the test-retest reliability of the ST. The correlations of the ST with timed up and go (TUG) and 10-m walk test (10MWT) were assessed for concurrent validity. RESULTS: Test-retest (ICC 0.90) reliability of the ST was determined to be excellent. The SEM and MDC95 values of test-retest reliability were 0.76 and 2.11, respectively. A significantly moderate correlation was found between the ST and TUG (p < 0.05, r: - 0.69), and 10MWT (p < 0.05, r: - 0.67). CONCLUSION: The ST is a valid and reliable method in the assessment of dynamic balance ability and locomotor function in patients with TKA. The ST can be used to quantify changes in dynamic balance level and locomotor function in patients with TKA.

OBJECTIVE: To investigate the effects of kinesio taping and cold therapy on pain, edema, range of motion, muscle strength, functional level and quality of life in patients with total knee arthroplasty. DESIGN: Randomised controlled trial. SETTING: A university hospital. SUBJECTS: One-hundred patients were included. INTERVENTION: Patients were allocated into three groups; control group, kinesio group and cold therapy group. The control group received a standard rehabilitation program. Kinesio taping group received two fan-shaped kinesio taping bands and cold therapy group received cold packs in addition to the standard rehabilitation program. MAIN MEASURES: The outcome measures were pain, edema, range of motion, muscle strength, functional level and quality of life. Participants were assessed at preoperative, discharge and postoperative third month. RESULTS: The groups were similar at preoperative. A significant difference was determined in terms of pain in kinesio taping group compared to the control group at the discharge. Cold therapy was efficient in reducing postoperative swelling but kinesio taping had no significant effects on swelling control. There was no difference between the groups in terms of range of motion, muscle strength, functional level and quality of life. The groups were similar in all parameters at the postoperative third month measurements. CONCLUSION: Fan-shaped kinesio taping is an effective technique in terms of postoperative pain relief. Cold therapy is an effective method in terms of edema control. Kinesio taping and cold therapy has no specific beneficial effect on functional level, muscle strength and quality of life compared to control group.

Local infiltration analgesia (LIA) is a simple, surgeon-administered technique for the treatment of postoperative pain after total knee arthroplasty (TKA). The aim of the study was to investigate the efficacy of LIA and its effects on functional outcomes in TKA. A total of 135 patients with primary TKA were recruited and randomized either to receive LIA or to receive placebo injection (PI). Pain, active range of motion (ROM), knee function score, functional activities, and hospital length of stay (LOS) were assessed before surgery and from postoperative day (POD) 1 to at discharge. Lower pain scores at rest were recorded on POD1 and POD2 in the LIA group (p = 0.027 and p = 0.020, respectively). Lower pain score on walking was recorded on POD1 in the LIA group (p = 0.002). There was a statistically significant difference in active knee flexion between groups on POD1 (p = 0.038). There was a significant difference in LOS between LIA and PI groups. Shorter stay was seen in LIA group. There were no statistically significant differences between the groups in terms of knee function score and functional outcomes. LIA technique is effective for pain management in the early postoperative period. LIA added benefit for knee function in terms of active knee flexion ROM after TKA. A shorter hospital LOS was observed in LIA group. However, we did not find any differences in groups in terms of functional assessment such as ability to rise from a chair and walking capacity.The level of evidence is randomized controlled trial, level I.

PURPOSE: The L test is a modified version of the timed up and go test (TUG), extending the walking distance from 6 to 20 meters and also requiring participants to make four turns in both (right/left) direction. It could be a useful measurement method in assessment of functional mobility for patients with Total Knee Arthroplasty (TKA). The aim of the study was to determine reliability, concurrent validity, and minimal detectable change (MDC) of L test in patients with TKA. MATERIALS AND METHODS: The study included 43 patients with TKA. The Intraclass Correlation Coefficient (ICC) was used to assess the intra-rater reliability of the L test. The correlations of the L test with TUG were assessed for concurrent validity. RESULTS: Intra-rater (ICC 0.97) reliability of the L test was determined to be excellent. The SEM and MDC95 values of intra-rater reliability were 1.03 and 2.84, respectively. A high correlation was found between the L test and TUG (r: 0.75). CONCLUSION: The L test is a valid and reliable method in the assessment of functional mobility in patients with TKA. The L test can be used to quantify changes in functional mobility level in patients with TKA.Implications for rehabilitationThe L test is a reliable and valid measurement tool that can be used to assess functional mobility in patients with TKA.Clinicians and researchers can use a greater change than 2.84 seconds for the L test as a meaningful change in patients with TKA.

BACKGROUND: Six-minute walk test (6MWT) is the most used test to assess functional capacity. Including arm span in the prediction equations for 6MWT performance might be an alternative for use in traditional reference equations. OBJECTIVE: The aim was to investigate the usability of arm span to predict the 6MWT distance in healthy children. METHODS: 262 healthy children aged between 6 and 12 years old participated in this study. 6MWT was conducted according to the standardized protocol. Height, weight, and arm span were measured before performing the 6MWT. A multiple stepwise linear regression analysis was used to generate the regression model. RESULTS: The 6MWT distance had strong positive correlations with age, arm span, height, and weight (p<0.001). There was also a very strong correlation between arm span and height (p<0.001). Age and arm span were found as significant predictors in the first regression model. These two variables explained 60.2% of the variance in the 6MWT distance. Age and height were also found as significant predictors, explaining 60.5% of the variance in the 6MWT distance. The two following formula were obtained to predict the 6MWT distance: (-23.09+(31.12×Age)+(2.39×Arm span)) or (-80.0+(28.98×Age)+(2.92×Height)). CONCLUSIONS: The results suggest that the combination of arm span (or height) and age are strong predictors of the 6MWT distance in healthy children.

PURPOSE: Performance-based outcome measures are becoming increasingly important in health care. The 2-minute walk test (2MWT) and the Timed Up and Go test (TUG) are frequently used in clinical trials as performance-based tests in many diseases including osteoarthritis. The purposes of this study were: (1) to determine test-retest reliability of data for the 2MWT and the TUG; (2) to determine minimal detectable change (MDC) scores for the TUG and 2MWT in patients with total hip arthroplasty (THA). METHODS: 37 patients, who had undergone primary THA, were included. Patients twice performed trials for the 2MWT and TUG on the same day. In addition to demographic data of patients, the Harris Hip Score, 2MWT and TUG scores were recorded. RESULTS: The TUG and 2MWT showed excellent test-retest reliability. The Intraclass correlation coefficient ICC (2,1), Standard error of measurement (SEM) and minimal detectable chance at the 95% CI (MDC95) for TUG were 0.96, 0.59 seconds and 1.62 seconds respectively. The ICC (2,1), SEM and MDC95 for 2MWT were 0.96, 6.37 m and 17.56 m respectively. CONCLUSION: Clinicians and researchers can be confident that greater changes than 1.62 seconds for TUG and 17.56 m for the 2MWT over time represent a real clinical change in rehabilitation process in patients with THA. Both the 2MWT and TUG may assist in early identification of patients who may need additional rehabilitation to reduce the potential for poor outcomes after THA. Therefore, both of these tests can be used in a clinical setting with a small measurement error.

OBJECTIVE: The aim of the study was to determine intrarater and interrater reliabilities for static strength assessment of knee flexors and knee extensors in patients with total knee arthroplasty, during the acute postoperative rehabilitation. DESIGN: Forty-five total knee arthroplasty patients were included in the study. Two physical therapists performed strength assessments by using hand-held dynamometry. Patients performed three trials and a 30-sec rest was provided between each trial. After this, a 5-min rest was provided, and then, a second investigator performed the same procedure for interrater reliability. Assessments for intrarater reliability were performed 1 hr later. RESULTS: The intrarater reliability of knee extensors and knee flexors strength measurements were 0.96 and 0.94, respectively. The standard error of measurement and minimal detectable change 95% confidence level were 6.17 and 17.01 Nm for knee extensors and were 8.89 and 24.51 Nm for knee flexors, respectively. The interrater reliability of knee flexors and knee extensors strength measurement was 0.96 for both. The standard error of measurement and minimal detectable change values at 95% confidence level were 6.00 and 16.54 Nm for knee extensors and were 6.32 and 17.42 Nm for knee flexors, respectively. CONCLUSIONS: Hand-held dynamometry is a reliable method to assess static knee strength. Hand-held dynamometry assessment can be implemented during acute postoperative rehabilitation. Our results may assist the clinicians in determining an accurate postoperative rehabilitation program after total knee arthroplasty surgery.

Background/aim: The 6-minute walk test (6MWT) is the most commonly used and well-established test to measure functional exercise capacity in research and clinical settings. Country-specific reference values are important to interpret the results of 6MWT. However, no reference values have been reported for healthy Turkish children aged between 6 and 12 years old. The aim of this study was to determine normal reference values for the 6MWT test of healthy Turkish children aged between 6 and 12 years old. Materials and methods: Two hundred and sixty-two healthy children aged between 6 and 12 years old were included in this cross-sectional study. Measures included height, weight, body mass index (BMI), leg length, and 6MWT distance (6MWD). Results: The mean 6MWD was 572.58 (SD = 117.72) m. There were significant correlations between 6MWD and age (r = 0.764, P < 0.001), height (r = 0.742, P < 0.001), weight (r = 0.605, P < 0.001), BMI (r = 0.234, P < 0.001), and lower extremity length (r = 0.708, P < 0.001). In the stepwise multiple linear regression model, age and height explained about 60% of the variability of the 6MWT distance for the total sample. Conclusion: Reference values and prediction equation for the 6MWT in healthy Turkish children aged 612 years old have been reported for the first time in this study. Researchers and clinicians can use them to interpret the effectiveness of a treatment and/or to compare the results of disabled children with healthy ones.

BACKGROUND: Evaluation of range of motion (ROM) is integral to assessment of the musculoskeletal system, is required in health fitness and pathologic conditions, and is used as an objective outcome measure. Several methods are described to check ROM, each with advantages and disadvantages. Hence, this study introduces a new device using a smartphone goniometer to measure ankle joint ROM. OBJECTIVE: To test the reliability of smartphone goniometry in the ankle joint by comparing it with the universal goniometer (UG) and to assess interrater and intrarater reliability for the smartphone goniometer record (SGR) application. METHODS: Fifty-eight healthy volunteers (29 men and 29 women aged 18-30 years) underwent SGR and UG measurement of ankle joint dorsiflexion and plantarflexion. Two examiners measured ankle joint ROM. Descriptive statistics were calculated for descriptive and anthropometric variables, as were intraclass correlation coefficients (ICCs). RESULTS: There were 58 usable data sets. For measuring ankle dorsiflexion ROM, both instruments showed excellent interrater reliability: UG (ICC = 0.87) and SGR (ICC = 0.89). Intrarater reliability was excellent in both instruments in ankle dorsiflexion: UG and SGR (mean ICC = 0.91). For measuring ankle plantarflexion, both instruments showed excellent interrater reliability: UG (ICC = 0.76) and SGR (ICC = 0.82). Intrarater reliability was excellent in both instruments in ankle plantarflexion: UG (mean ICC = 0.85) and SGR (mean ICC = 0.82). CONCLUSIONS: Smartphone-based goniometers can be used to assess active ROM of the ankle joint because they can achieve a high degree of intrarater and interrater reliability.

AIMS: The functional reach test (FRT) and lateral reach test (LRT) provide important measures of postural stability. The aims of this study were to (1) establish the normative values for FRT and LRT, and (2) examine the effects of age, gender, and various anthropometric measurements on FRT and LRT. METHODS: Two hundred eighty children, aged 6-12 years, completed the study. One hundred fifty-two subjects were females. The mean age was 9.0 ± 2.0 years. Each child performed two trials of FRT and LRT. RESULTS: No significant differences were detected in any age group between males and females. The normal values of FRT ranged between 23.0 and 36.5 cm, and that of LRT between 18.0 and 28.0 cm. Height, length of upper and lower extremity, and arm span had a higher correlation with FRT. Age and weight showed a good correlation with FRT. Age, height, weight, length of upper and lower extremity, and arm span showed good correlation with LRT. CONCLUSIONS: These normative data will be useful for clinicians in the assessment of balance of individual children and in the diagnosis of potential balance deficits at an early age in the Turkish population.

PURPOSE: To investigate the test-retest reliability of the 4-meter walk test (4 MWT) and 10-meter walk test (10 MWT) in patients undergoing lower extremity surgery during inpatient rehabilitation. METHOD: In all, 102 patients with total hip arthroplasty (THA), total knee arthroplasty (TKA), lower extremity fracture (LEF) and soft tissue operation were recruited. Patients performed two 4 MWT and two 10 MWT trials on the same day. The same researcher performed all the measurements to avoid inter-rater variability. RESULTS: The 4 MWT and 10 MWT were shown to have excellent test-retest reliability. The ICCs for the 4 MWT and 10 MWT were found as 0.94 and 0.95, respectively. The SEMs for the 4 MWT and 10 MWT were 2.0 and 5.5 seconds, respectively. The smallest real difference at the 95% confidence level (SRD95) was 5.5 seconds for the 4 MWT and 12.2 seconds for 10 MWT and SRD95 percentage was 31.2 for the 4 MWT and 28.5 for the 10 MWT. CONCLUSION: Both the 4 MWT and the 10 MWT have excellent reliability in patients undergoing lower extremity surgery such as TKA, THA, LEF and soft tissue operation during inpatient rehabilitation. Clinicians and researchers can be confident that changes above the SRD95s for the different patient groups, for both sexes and with regard to weight-bearing status, represent a real clinical change in rehabilitation process. Implications for Rehabilitation The 4 MWT and the 10 MWT are simple methods and were also shown to be reliable measurement methods in many patient groups. This study illustrates that the test-retest reliability of the 4 MWT and 10 MWT are excellent in patients undergoing lower extremity surgery during inpatient rehabilitation (ICC: 0.94 for 4 MWT, ICC: 0.95 for 10 MWT). Clinicians and researchers can be confident that changes above the SRD95s for the different patient groups, for both sexes and with regard to weight-bearing status represent a real clinical change in rehabilitation process.

BACKGROUND: Two-minute walk test (2MWT) and the Timed Up and Go test (TUG) are simple, quick, and can be applied in a short time as part of the routine medical examination. They were shown to be reliable and valid tests in many patient groups. The aims of the present study were: (1) to determine test-retest reliability of data for the TUG and 2MWT and (2) to determine minimal detectable change (MDC) scores for the TUG and 2MWT in patients with TKA. METHODS: Forty-eight patients with total knee arthroplasty, operated by the same surgeon, were included in this study. Patients performed trials for TUG and 2MWT twice on the same day. Between the first and second trials, patients waited for an hour on sitting position to prevent fatigue. RESULTS: The TUG and 2MWT showed an excellent test-retest reliability in this study. Intraclass correlation coefficient [ICC(2,1)] for TUG and 2MWT were 0.98 and 0.97, respectively. Standard error of measurement and MDC95 for TUG were 0.82 and 2.27, respectively. Standard error of measurement and MDC95 for 2MWT were 5.40 and 14.96, respectively. CONCLUSION: The TUG and 2MWT have an excellent test-retest reliability in patients with TKA. Clinicians and researchers can be confident that changes in TUG time above 2.27 seconds and changes in 2MWT distances above 14.96 meters, represent a "real" clinical change in an individual patient with TKA. We, therefore, recommend the use of these 2 tests as complementary outcome measures for functional evaluation in patients TKA.

OBJECTIVES: Although a relationship between short pectoralis minor and upper trapezius and scapular dyskinesis has been postulated, no studies have investigated this theory. Understanding the effect of these muscle lengths on observable scapular dyskinesis may aid in determining risks and therefore making treatment decisions. Being aware of the magnitude of this effect would help gauge the significance of risks involved. Our aim was to evaluate the influence of pectoralis minor and upper trapezius lengths on scapular dyskinesis. DESIGN: Cross-sectional study. SETTING: University research laboratory. PARTICIPANTS: Asymptomatic participants (n = 148; 296 arms) were evaluated. MAIN OUTCOME MEASURES: Scapular Dyskinesis Test (SDT) was used to identify scapular dyskinesis, Pectoralis Minor Index (PMI) and Upper Trapezius Length Testing were used to determine muscle length. RESULTS: SDT+ arms had shorter pectoralis minor resting length (PMI: 7.49 ± 0.38) (p < 0.001) and greater incidence of short upper trapezius (ISUT) (66.7%) (p < 0.001) compared to SDT- arms (PMI:8.58 ± 0.75, ISUT:22.5%). With each decrease in PMI, the likelihood of having scapular dyskinesis increased 96% (p < 0.001). Arms with short upper trapezius were 2.049 times more likely to exhibit scapular dyskinesis than those with normal length (p = 0.042). CONCLUSIONS: Having a shorter pectoralis minor and upper trapezius length substantially increased the likelihood of having visually observable scapular dyskinesis.

The purpose was to investigate the test-retest reliability of the 50-Foot Timed Walk (50FWT), and 30-Second Chair Stand Test (30CST) in the patients with total hip arthroplasty (THA). The study was a test-retest study. Thirty-seven patients with THA performed two trials for both the 30CTS and 50FWT on the same day with one hour interval. To assess reliability, the intra-class correlation coefficient [ICC(2,1)], standard error of measurement (SEM), the smallest real difference at the 95% confidence level (SRD95) were calculated. The ICCs for the 50FWT and 30CTS were 0.98 and 0.94, respectively. The SEM and SRD95 for the 50FWT and 30CTS were 0.3 and 0.8 seconds and 0.4 and 1.2 repeats, respectively. The test-retest reliability of the tests was very high. The 50FWT and 30CST are very reliable to measure the functional performance in patients with THA in the clinical settings.

OBJECTIVE: To investigate the reliability of the 50-Foot Walk Test (50 FWT) and 30-second Chair Stand Test (30 CST) in patients who have undergone total knee arthroplasty (TKA). METHODS: The study was designed as a test-retest research. Thirty-three patients who would undergo bilateral TKA were recruited. The tests 30 CST and 50 FWT were performed twice on the same day with 5-minute intervals, respectively. Between the first and second tests, patients waited for an hour on sitting position in order to prevent fatigue. In addition to these tests, we registered the knee pain experienced by the patients using a 100 mm VAS scale. RESULTS: The 50 FWT and 30 CST showed excellent reliability. ICC for 50 FWT and 30 CST were 0.97 and 0.92, respectively. SRD95 was 1.07 for 50 FWT and 0.96 for 30 CST. CONCLUSIONS: According to results of this study, both 50 FWT and 30 CST have excellent reliability in patients with TKA. These tests are simple, no time consuming and constitute sensitive methods to measure the functional performance in patients with TKA in the clinical settings. Clinicians and researchers may use these tests to quantify even small changes in functional performance for patients with TKA. Level of Evidence III, Diagnostic Study.

PURPOSE: Stair climbing is one of the important functional activities of daily living to maintain mobility and independence. Walking and stair climbing have been identified by clinicians and patients as critical functional activities before and after total hip arthroplasty (THA). Testing the ability to manage steps has been commonly used in clinical and research settings because it is an inexpensive and simple way to measure functional status after THA. The frequent use of this test supports studies seeking evidence to validate stair test (ST) as a measure of physical performance in subjects with THA. The aim of this study is to determine the test-retest reliability of the 9-step ST in patients with THA. METHODS: Patients performed twice trials for the ST on the same day with one hour interval. To assess test-retest reliability, the intra-class correlation coefficient--ICC (2,1), standard error of measurement (SEM), minimal detectable change at the 90% confidence level (MDC90) were calculated. RESULTS: A total of 37 patients with THA participated in this study. The ST showed very high reliability (ICC = 0.98 (95% CI, 0.96 to 0.99)). The SEM was 0.3 seconds and the MDC90 was 0.7 seconds. CONCLUSIONS: Test-retest reliability of the ST was very high for the patients with THA, and the SEM and MDC90 were adequate for clinical use. The ST is less time consuming and has very high reliability to measure the functional level after THA in the clinical setting.

BACKGROUND: Walking ability is a crucial component of lower extremity function. Assessment of walking after total hip arthroplasty (THA) provides important information about the healing process. Walking endurance, an important functional component of walking, can be reliably measured with the 6-minute walk test (6 mWT). Even though the 6 mWT is commonly used in patients with THA, its reliability has never been reported for this patient population. The aim of this study is to assess the reliability of the test-retest 6 mWT after THA. METHODS: Thirty-four patients with THA performed two test trials on the same day, separated by a one hour seated rest. To assess reliability, intra-class correlation coefficient (ICC(2,1)), standard error of measurement (SEM), and smallest real difference (SRD) were calculated. RESULTS: The 6 mWT showed a high reliability. The patients walked 3.71 metres more at the end of the second 6 mWT in comparison with the first test. The ICC(2,1) (AS(95)), SEM (m), SEM(95) (m) and SRD(95) (m) were 0.96 (0.92), 3.67, 7.19, and 10.17 m respectively. CONCLUSIONS: Reliability of the 6 mWT was high in patients with THA. The 6 mWT is a simple and sensitive method to measure the functional performance in patients with THA in the clinical setting. Moreover, clinicians and researchers can use the 6 mWT to quantify even small changes in functional performance after THA.
