Abstract Background: Knee osteoarthritis is a degenerative joint disease affecting the aging Filipino population. Outcome measure tools are used to assess a patient’s health status for the quality of care improvement. With the increasing prevalence of knee osteoarthritis, it warrants the need to conduct a clinical audit to identify the most common outcome measure tools used by Filipino Physical Therapists. Objectives: To determine the outcome measure tools used by Filipino Physical Therapists in assessing knee osteoarthritis in hospitals and clinics and compare it to the current global standard of assessment. Methods: A retrospective record audit study design was used to determine the current assessment tool compared with standards of assessment. Results: Of the 45 of 285 charts reviewed, 80% were females and 73.33%, aged older than 60 years. The following were examination tools used by Physical Therapists: In Subjective; a. pain score (97.77%), b Functional status (80%), and c. stiffness ( 4.44%). In Objective; a. ocular inspection and palpation(97.77% ), b. range of motion and manual muscle testing (93.33%), c. posture ( 48.89%), d. special tests (33.33%), e. gait analysis ( 71.11%), and f. Functional assessment ( 91.11%). Physical Therapists did not use Western Ontario and McMaster Universities Osteoarthritis (WOMAC), Visual Analog Scale (VAS), Short Form-36 (SF-36), and Knee Injury and Osteoarthritis Outcome Score ( KOOS) outcome measures for assessing knee osteoarthritis. Conclusion: Physical Therapists did not use standardized outcome measure tools in the assessment for knee osteoarthritis. Thus, the study shows the gap in the assessment for knee osteoarthritis in the Philippines and global standards.

The senior investigator of this study trained four researchers on the use of the validated data extraction form. Inter-rater reliability of four researchers on the use of data extraction form was determined. The four researchers independently extracted data from the Subjective, Objective, Assessment, Plan (SOAP) notes written by a physical therapist on the PT chart of a patient who underwent physical therapy treatment. Inter-rater reliability was computed using the Kappa Coefficient, specifically Fleiss Kappa. A range from -1 to +1, where 0 represents the amount of agreement expected from random chance, and 1 represented a perfect agreement between the raters.12 Phase 4: Clinical Audit.

Abstract Background: Inversion ankle sprains are among the most common traumatic injuries for both men and women caused by jumping and landing activities. The ankle is protected by the static and dynamic stabilizers to reduce the incidences of injuries. Furthermore, using a non-elastic closed- basket weave taping technique is one of the common interventions to prevent it. Knowledge about the muscle activity reaction of the dynamic stabilizers upon application of tape is limited with varying results. Objectives: To determine the effect of non-elastic closed-basket weave ankle taping on the muscle activity of tibialis anterior, peroneus longus, medial, and lateral gastrocnemius on healthy individuals during jump landing on a hard, flat surface. Methods: This study is a quasi-experimental study using a pre- and post-test design. Peak amplitude muscle activity was assessed and analyzed using surface electromyography (sEMG) after landing from a jump. The pre-test was done by jump landing without tape, after which post-test data was immediately collected after applying the non-elastic closed-basket weave taping. Jump landing was done for three trials for both pre- and post-tests. A paired t-test was used to determine significant differences in pre-post taping. Results: Fifteen healthy participants were included in the study (9 females, 6 males) with a mean age of 21 + 1.03 years old and BMI of 22.74 + 1.63 kg/m2. No significant difference was observed on peak amplitude muscle activity of the tibialis anterior (p= 0.06), medial gastrocnemius (p= 0.32), and lateral gastrocnemius (p= 0.66) after application of tape. However, a significant difference was observed in the peroneus longus after the application of tape (p= 0.05) during jump landing. Conclusion: Non-elastic closed-basket weave taping decreased the peak amplitude muscle activity of the peroneus longus during jump landing. This research suggests that tape may influence the peroneus longus, and it may or may not be detrimental in reducing the risk of ankle sprains.

The leg muscles help studies have shown that jumping and drop stabilize the ankle in one fixed position during landing are often the mechanisms involved in the the landing phase, through which different acquisition of ankle sprains during cutting injuries can be prevented. Among these muscles maneuvers and jump landing tasks in field are the peroneus longus, which acts as a primary hockey, high jumps, tennis, and basketball defense mechanism of an injured ankle,10 the games.6 When an individual starts to jump, the gastrocnemius,8,9 and the tibialis anterior, which ankle moves from a dorsiflexed to a allows dorsiflexion to handle landing stability.11 plantarflexed position, then upon landing, it A study by Ebben10 showed a significant effect of moves from plantarflexion to dorsiflexion.

The ankle the involvement of the hip and knee muscles is protected by its static and dynamic stabilizers. during jumping and landing activities. In a study Static stabilizers are bone articulations and done by Walsh,8 wherein they observed the ligaments that support the ankle. In contrast, muscle activity immediately after contact in dynamic stabilizers are the muscles firing around jump landing. The gastrocnemius is seen to be the joint for stability.5 Eccentric control is noted contracting first for ankle stabilization, followed to lessen the forces acting between the ground by the contraction of the biceps femoris and and the ankle joint, which is the dynamic rectus femoris.

Abstract 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. Keywords: gluteus medius, tibialis anterior, peroneus longus, muscle activation, landing INTRODUCTION Landing is commonly performed in human and BOSU ball.14 Unstable surfaces are as equally locomotion1,2 especially in sports. Drop landing is important to be considered as stable surfaces an isolated landing with no subsequent motion.3 due to the modifications of musculoskeletal Examples include a gymnast performing a loading in response to changing surfaces.10 Due dismount, landing after a rebound of a basketball to large loads absorbed by the musculoskeletal player, or landing of a volleyball player after spiking the ball.3-6 This plays an important role in system upon landing, strategies to reduce and successful sports performance7,8 for it reduces control the reaction force must be initiated the total body momentum, absorbs impact load, before impact.10 Strategies including muscle and prevents injuries.9,10 It is also where most activation and segment kinematics before injuries, such as ankle sprain, occur. landing require synergistic work10,15 by multiple muscles and segments of the lower extremity In sports, landing occurs on stable and unstable specifically the hip and ankle16,17 to work in surfaces.11 The latter is defined as any surface synergy. The muscle activation pattern of the that is unsteady, not fixed or not firm.12 This can lower extremity during drop landing works for include trampolines, wobble boards13, foam11, absorbing the stress of the impact of landing and stabilization of the lower extremities to avoid 31
