Background: Gluteus medius (GMeds), peroneus longus (PL), and tibialis anterior (TA) help in maintaining frontal stability of the lower extremity, particularly, the ankle. Muscle activation must be sufficient to prevent the occurrence of an ankle sprain. The purpose of this study is to compare the muscle activation of the GMeds, TA, and PL during drop landing on stable and unstable surfaces of physically active individuals. Methods: Surface EMG (sEMG) was used to determine the muscle activation pattern of the GMeds, TA, and PL of fifteen ( 15) recreational athletes during drop landing. The mean percentage of maximum voluntary isometric contraction (%MVIC) was calculated for comparison. Wilcoxon signed-rank test was used to compare means. Results: There were no statistically significant differences in the muscle activity of GMeds (p=0.69), TA (p=0.26), and PL (p=0.23) on stable and unstable surfaces. However, a small effect size showed that GMeds (d=0.30) has higher activation in the unstable surface while TA (d=0.28) and PL (d=0.17) have lower activation on unstable surface. Conclusion: Landing surface does not significantly alter muscle activity of GMeds, TA, and PL. However, the magnitude of the difference in the mean %MVIC between groups shows the compensatory mechanism of the body when subjected to different surface conditions. This can be used when creating injury prevention programs of the lower extremity.

Background: Muscular imbalance in the core and hip is one of the major risk factors associated with PFPS. There is evidence that decreased strength of the hip musculature is present in individuals with PFPS. This decrease in hip strength can also affect the stability of the core and further predisposes an athlete to injury. Objectives: This is a cross-sectional study that compares the hip muscle strength and core stability of collegiate football players with and without PFPS. Methods: 25 participants (10 with PFPS and 15 without PFPS) participated in the study. Hip strength was measured using a digital handheld dynamometer. Core stability was assessed through the McGill Core Strength test and the 8-stage stability test. Results: The hip adductors showed to be significantly weaker in those with PFPS as compared to those without PFPS (p=0.040). No differences were found in the hip flexor (p=0.812), hip extensor (p=0.460) and abductors (p=0.126) strength while the core musculature showed that there is a statistically significant difference on the endurance of the lateral core musculature (p<0.001) and trunk flexors (p=0.027) between the two groups. Conclusion: Football athletes without PFPS in this study demonstrated greater core stability and hip adductor muscle strength compared to those without PFPS.

Background Patellofemoral pain syndrome is the most common knee condition and is associated with patellar maltracking. Ultrasound is used in studying patellar maltracking. The objective is to determine if the technique which analyzes the displacement of the patellar tendon in the trochlear sulcus is associated with patellofemoral pain syndrome. Methods In total, 68 knees of 34 football players (males = 20, females = 14) were included. Patellar tendon displacement was assessed in supine and standing positions. Patellar tendon displacement difference in the two positions was determined. Results There was a significant difference in the lateral patellar tendon displacement during standing which was larger in patellofemoral pain syndrome than without patellofemoral pain syndrome (Mean Rank = 39.20 vs. 30.32, p = 0.02). There was no significant difference between the two groups for lateral patellar tendon displacement in supine and the difference in patellar tendon displacement from supine to standing. Conclusion The technique could be a potential method in assessing patellar maltracking. It could be used to have a comprehensive understanding of the pathomechanics and treatment of patellofemoral pain syndrome.

Aim: To determine acceptance of telerehabilitation, accessibility to technological resources, and technical literacy, and determine the relationship between mentioned variables among older adults with hypertension. Methods: This cross-sectional analytic study collected data through an online survey using the Web-Based Patient-Reported Outcomes Capture System-Needs, Acceptance, and Readiness Assessments questionnaire. Purposive sampling was used through the assistance of partner communities from UST Simbahayan. Relationships between independent (socio-demographics and readiness) and dependent variables (acceptance) were analyzed through robust regression (p-value<0.0001) using STATA. Results: Most older adults (n = 174) were female and had secondary schooling. The overall acceptance of telerehabilitation was measured through a 4-point Likert scale (Mean = 3.42; Median = 3.57). In terms of readiness, the majority have computer access and internet access at home but have a frequency of use of less than a month. Younger age increased acceptance by 0.48%, while a college graduate increased acceptance by 13%. Living in Laguna and Rizal also increased acceptance by 13% and 26%, respectively. In contrast with past studies, this research revealed that frequency of ICT use and Internet access are not predictive of acceptance of telerehabilitation. Conclusion and Implications: Younger age, higher educational attainment, place of residence, and computer access at home were predictive of acceptance of telerehabilitation. The results suggest the need to include other quantitative aspects of telerehabilitation readiness. The findings of the study may aid in identifying the readiness of other communities in receiving telerehabilitation and addressing the barriers to implementing telerehabilitation.
