RESUMEN
Objectives: The aim of this study was to investigate the intrarater and interrater reliability and validity of range of motion measurements obtained with a universal goniometer, digital inclinometer, and smartphone application in patients with total knee arthroplasty. Methods: Range of motion of the knee joint was measured by two examiners with a universal goniometer, digital inclinometer, and a smartphone application. Data were obtained from 51 knees of 27 patients at postoperative 6 months. Two measurements made by the first examiner were compared to assess interrater reliability, and measurements from both examiners were compared to assess intrarater reliability. Statistical analysis was performed using intraclass correlation coefficient (ICC) and Spearman's rho values. Results: With all three methods, active and passive knee flexion range of motion measurements showed high intrarater and interrater reliability (ICC = 0.749-0.949). Concurrent validity analysis also demonstrated statistically significant, moderate to strong correlation among the three methods (r = 0.775-0.941). Conclusion: The universal goniometer, digital inclinometer, and smartphone application were all found to be reliable and valid assessment tools in clinical practice for patients with total knee arthroplasty.
RESUMEN
BACKGROUND: Taping stimulates the mechanoreceptors, increases sensory information to the central nervous system, and improves sensorimotor synchronization, resulting in improved motor control. However, the efficacy of taping on elbow proprioception is not clear. PURPOSE: This study aimed to evaluate the immediate effects of taping on elbow proprioception in healthy individuals. STUDY DESIGN: This study was a two-arm, parallel-group, randomized, controlled, single-blinded study with a sham application. METHODS: Fifty six healthy adults were randomized 1:1 to kinesio taping (n = 27) or sham taping (n = 29). Active joint position sense error (JPSE) was used to quantify proprioception using a universal goniometer at three-time points: baseline (BS), immediately after taping (IA), and 30 minutes after taping (30MA), with the tape still in place at 70° and 110° of elbow flexion. Participants were blinded to group assignments. The Friedman analysis assessed differences between evaluations within groups, and the Mann-Whitney U test determined differences between groups. RESULTS: The study was completed with 56 participants and there were no dropouts. No skin reaction or adverse effect was observed in the participants and no test trial was excluded. The baseline scores of the groups were similar (p > 0.05). A significant difference was detected in the study group after kinesio taping at 70° (MD = -1.22; CI = (-2.33: -0.10; p < 0.005; d = 0.653) and 110° of elbow flexion (MD = -1.34; CI = 2,47: -0,21; p < 0.005; d = 0.73). This statistically significant difference was observed even at the 30MA evaluations at 70° (p < 0.05). Also, there was a statistically insignificant tendency to decrease in JPSE of both groups at both degrees following taping. CONCLUSIONS: Elbow proprioception may be enhanced by kinesio taping, and this effect could last up to 30 minutes at 70° of elbow flexion. In contrast, sham taping did not produce such an improvement. Based on the differences in JPSE, kinesio taping proved more effective and had a longer-lasting impact than the sham application. The statistically insignificant tendency to decrease in JPSE may indicate that the 30-minute application period is inadequate to create a statistically significant effect on elbow proprioception. Longer usage periods can better reveal the effects of orthoses on proprioception.

BACKGROUND: Practical, applicable, valid, and reliable tools are needed to assess physical performance in patients with Total Knee Arthroplasty (TKA) in a variety of settings, including routine clinical assessment, research studies, and community-based programs. OBJECTIVE: The aim of this study is to evaluate the validity and reliability of the Short Physical Performance Battery (SPPB) among patients with TKA. METHODS: We included 45 patients who underwent TKA surgery (mean age 68.89 ± 9.26). The SPPB, Timed up and go (TUG) test and, Hospital for Special Surgery (HSS) Knee Score were administered to the patients. SPPB was performed twice on the same day with 1 h rest. RESULTS: The ICC(2,1) coefficient, MDC95 and SEM values were 0.97, 1.02 and 0.37 respectively. The Pearson correlation coefficient of the SPPB with the TUG and HSS was -.78, and 0.74 respectively. CONCLUSION: SPPB has excellent reliability, and strong validity in assessing physical performance in patients with TKA. SPPB can identify even minimal detectable difference in physical performance and can be reliably used to monitor patient outcomes in the postoperative period for a comprehensive assessment of TKA in many physical performance domains, including balance, walking speed, and lower extremity strength.

RESUMEN
BACKGROUND: Under dual-task (DT), functional mobility and balance testing can detect balance and mobility problems in activities of daily living, especially in situations that cannot be identified under single-task conditions. OBJECTIVE: Determine the test-retest reliability and concurrent validity of the Four Square Step Test (FSST) under DT conditions for people with total knee arthroplasty (TKA). METHOD: A total of 30 patients with TKA participated in this research, and patients were tested with the FSST under DT conditions. In addition, concurrent validity of the dual-task FSST was calculated using Timed Up and Go (TUG) under the single-task condition and Hospital for Special Surgery (HSS) Knee Score. Patients performed two FSST trials on the same day under DT conditions. RESULTS: The intraclass correlation coefficients (ICC2,1) two-way random effects model, and minimal detectable changes with 95% confidence intervals (MDC95) values of the FSST under DT conditions were .97 and 3.43, respectively. The Pearson's correlation coefficient of the FSST with the TUG and HSS was .65 and -.40, respectively. CONCLUSION: The FSST has been found to be a reliable and valid clinical assessment tool for dynamic balance under DT conditions in patients with TKA. For identify balance disorders in daily life at early points, clinicians and researchers can use the FSST under DT conditions in TKA. CLINICAL TRIAL REGISTRATION NUMBER: NCT06108466.
RESUMEN
BACKGROUND: Improving proprioception can reduce the risk of injuries, while its disruption may lead to injuries and recurrent or persistent symptoms. PURPOSE: This study aimed to evaluate the immediate effects of elbow orthoses on elbow proprioception in asymptomatic individuals. STUDY DESIGN: This was a randomized, controlled, single-blinded study with a sham application. METHODS: Sixty participants were equally distributed into three orthosis groups (counterforce, sleeve, and sham). Proprioception was assessed using active joint position sense error (JPSE) at 70° and 110° of elbow flexion at three time points: baseline (BS), immediately after (IA) wearing the orthosis, and 30 minutes after (30MA) wearing the orthosis. RESULTS: Between groups: No significant difference in JPSE was observed at 70° (p = 0.095); however, there was a significant difference at 110° (p = 0.005). Between time points: At 70°, JPSE did not exhibit a significant difference (p = 0.055), whereas a significant difference was observed at 110° (p = 0.020). Interaction of time points×groups: No significant interaction was observed either at 70° (p = 0.476) or at 110° (p = 0.346). At 70°, within the sleeve group, significant differences were identified between BS-30MA (p = 0.001) and IA-30MA (p = 0.009). At 110°, in the sleeve group, significant differences were observed between BS-30MA (p = 0.007) and IA-30MA (p = 0.007). In the counterforce group, significant differences were identified between BS-30MA time points (p = 0.001). At 70°, no difference was observed within the overall evaluation in the counterforce group (p > 0.05), whereas at 110°, a significant difference was noted (p = 0.026). At both 70° and 110°, no differences were identified within the overall evaluation in the sleeve and sham groups (p > 0.05). CONCLUSIONS: In asymptomatic individuals, sleeve orthosis improved elbow proprioception at 70°, whereas both counterforce and sleeve orthoses were effective at 110°.

ABSTRACT Objective: This study evaluated the physical and functional characteristics of Turkish patients with knee osteoarthritis and how this disease affects their physical and functional status. Methods: This study included 320 patients, who were evaluated to assess body mass index (BMI) and Hospital for Special Surgery (HSS) score in terms of age, sex and functional characteristics. Results: Mean patient age was 66.92±8.89 years and mean BMI was 31.02±5.20 kg/m2. Mean patient HSS score was 58.70±11.08. According to their sit-to-stand test results, 33% of the patients (n=104) were found to be independent. There was a significant relationship between BMI and functional activity score (p<0.05). Conclusions: The majority of the patients in our study were female and obese, and had low functionality levels. Function in patients with OA is restricted as a result of excess weight, so preventive measures can help Turkish patients with OA maintain their ideal weight. Furthermore, patient education can be help this population acquire the habit of regular exercise in order to reduce pain and improve their physical activity and quality of life.

RESUMEN
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.
