Published: August 2021

Background Assessment of inter-limb kinetic symmetry during landing could provide valuable insights when working with athletes who have undergone anterior cruciate ligament reconstruction. However, it is difficult to determine if the asymmetry exhibited by an injured athlete is excessive or within a range that is similar to uninjured athletes, until normative values are established. Purpose The purpose of this study was to establish normative values for inter-limb impact force symmetry in uninjured adolescent athletes. In addition, an example is provided of how these normative values could be used to identify athletes who exhibit atypically high levels of asymmetry following anterior cruciate ligament reconstruction. Study Design Cross-sectional study Methods One hundred and thirty-six uninjured athletes completed drop vertical jumps and countermovement jumps while force plates recorded ground reaction forces. Symmetry indices captured inter-limb symmetry in impact forces during landing for both tasks. These symmetry indices were also combined to create an index that captured symmetry across both tasks. Normative values were established using the uninjured athletes’ data. Eleven athletes who had undergone anterior cruciate ligament reconstruction and been cleared to return to landing and jumping performed the same tasks and their data were compared to the results for the uninjured group. Results Measures of central tendency, variability, percentiles, and outliers were calculated/identified based on the uninjured athletes’ symmetry indices. Six of the 11 injured athletes exhibited atypically high symmetry index values. Conclusion The normative values established as part of this study may serve as a basis for identifying athletes who exhibit atypically high levels of inter-limb impact force asymmetry during jumping tasks following anterior cruciate ligament reconstruction.

Published: August 2021

Background Very limited investigations have been conducted exploring risk factors for injury in water polo players. A gap remains in the literature regarding identification of variables that should be considered as part of player screening evaluations. Purpose To estimate whether previous injury, changes in strength, range of motion (ROM) or upward scapular rotation (UR) are related to shoulder injuries in water polo players. Study Design Descriptive cohort study Methods Thirty-nine international-level players participated (19 males). Shoulder internal (IR) and external rotation (ER) peak torque was measured using an isokinetic device (CONtrex MJ). Shoulder ROM was measured passively using standard goniometry. Scapular UR was measured using a laser digital inclinometer. At baseline players were divided into groups: those with and without previous shoulder injuries. Independent t-tests and Mann-Whitney U tests were used to compare the study variables between groups. After nine months, a second analysis compared the same athletes, who were then grouped by those who had or had not sustained new injuries. Effect sizes were calculated with a Hedge’s g. Chi squared analysis compared proportion of injured players with and without previous injury. Results Eighteen participants (46%) had previous injuries at baseline. Players with a previous injury showed higher peak torques for IR (0.62±0.15 vs 0.54±0.13N/kg, p=0.04, g=0.60); larger loss of IR ROM (9.9±9.1 vs 4.1±7.5°, p=0.04, g=0.68), but no statistical difference in UR (p=0.70). After nine months, there were no statistical strength differences between groups. Loss of IR ROM was significantly higher in the injured group (9.8±9.8 vs 4.0±6.7°, p=0.04, g=0.68), as well as UR (13.0±3.0 vs 10.4±3.3°, p=0.01, g=0.81). History of previous injury was significantly related to developing a new injury (OR 6.5, p=0.02). Logistic regression found previous injury and UR most important contributors to injury risk. Conclusions Previous injury, changes in IR ROM and UR are related to new shoulder injuries in water polo, but further variables such as rest, training load, or psychosocial factors may explain the incidence of new injuries.

Authors: Abassi Mohsen , Whiteley Rod 
Published: August 2021

Background Persisting reductions in ankle dorsiflexion range of motion are commonly encountered clinically and seen to be associated with adverse outcomes after ankle and other lower extremity injuries. Accordingly improving identified deficits is a common goal for rehabilitation; however, little data exists documenting any improvement related to interventions in these patients. Purpose To document the change in dorsiflexion range of motion after stretching and mobilization-with-movement and exercise and a novel manipulation intervention in a population of injured athletes. Design Case series in 38 consecutive injured athletes with persisting reductions in ankle dorsiflexion range of motion (42 “stiff” ankles, 34 uninjured) in an outpatient sports physiotherapy clinic. Method During a single treatment session, two baseline measurements of weight-bearing dorsiflexion were taken at the start of the session to establish reliability and minimum detectable change, and then the same measures were performed after stretching and a mobilization-with-movement intervention, and again after clinical exercise and a novel manipulation which was applied on both ankles. Results Excellent reliability was demonstrated (ICC2,1>0.93, MDC=3.5°) for the dorsiflexion measure. Statistically significant (p<0.01), but clinically meaningless improvements were seen after stretching and the mobilization-with-movement intervention on the injured and uninjured legs (1.9° and 1.4° respectively) with greater improvements seen after exercise and the subsequent manipulation (6.9° and 4.7°). Conclusions The relatively simple clinical exercise and manipulation intervention program was associated improvement in dorsiflexion range of motion in this cohort with persisting ankle stiffness. The interventions described largely restored range of motion consistent with baseline levels of the uninjured ankles. Improvements were also seen in the uninjured ankles following intervention.

Published: August 2021

Background Fatigue may play a role in anterior cruciate ligament (ACL) injury, but has not been incorporated into objective test batteries for return to sport decisions following ACL reconstruction (ACLR) surgery. The effect of fatigue on muscle function and performance following surgery and rehabilitation has been poorly studied. Purpose/Hypothesis The purpose of this study was to assess the effect of fatigue on performance of various hop tests used in clinical rehabilitation settings by examining LSI scores. The authors hypothesized that participants will have worse limb symmetry index scores following the fatigue protocol and that the operative limb (ACLR) will have a greater decline in function than the non-operative limb (CON). Study Design Cross-Sectional Study. Methods Participants (n=21 [Male = 15, Female = 6]; AGE = 24.6 ± 9.3) were at least six months post ACLR and in rehabilitation. Testing was performed over two separate sessions in either a non-fatigued (NFS) or fatigued state (FS). In the FS, individuals performed a series of exercises to exhaust muscular endurance, strength, and power systems, after which they performed as battery of seven hop tests (single hop for distance, triple hop for distance, crossover hop for distance, 6-meter timed hop, lateral rotation hop for distance, medial rotation hop for distance, and vertical jump for height). A 2(limb) x 2(time) ANOVA was used to compare limbs between each state. Results Differences between limbs (CON vs ACLR) were observed for all hop tests in the NFS whereby the ACLR limb was observed to have reduced performance (↓5.4-9.1%, p <0.05). When tested in the FS, significant differences in performance between limbs remained for only the crossover (↓4.9%), medial rotation (↓7.1%), lateral rotation (↓5.5%), and vertical hop (↓10.0%)(p<0.05). When comparing the NFS and FS states, only the CON limb was observed to have significant decreases in performance of the Triple Hop (↓7.4%), Crossover (↓8.7%), and Lateral Rotation (↓5.2%)(p<0.05). Conclusions Following ACL reconstruction, there appears to be a greater loss in jump performance in the CON limb in the FS. These findings suggest it may be crucial to consider and assess the endurance of both limbs rather than just the ACLR limb when determining readiness for return to play. Level of Evidence Level 3

Published: August 2021

Background Blood flow restriction (BFR) training has been reported to have significant benefits on local skeletal muscle including increasing local muscle mass, strength, and endurance while exercising with lower resistance. As a result, patients unable to perform traditional resistance training may benefit from this technique. However, it is unclear what effects BFR may have on other body systems, such as the cardiovascular and pulmonary systems. It is important to explore the systemic effects of BFR training to ensure it is safe for use in physical therapy. Purpose The purpose of this study was to systematically review the systemic effects of blood flow restriction training when combined with exercise intervention. Study Design Systematic review. Methods Three literature searches were performed: June 2019, September 2019, and January 2020; using MedLine, ScienceDirect, PubMed, Cochrane Reviews and CINAHL Complete. Inclusion criteria included: at least one outcome measure addressing a cardiovascular, endocrinological, systemic or proximal musculoskeletal, or psychosocial outcome, use of clinically available blood flow restriction equipment, use of either resistance or aerobic training in combination with BFR, and use of quantitative measures. Exclusion criteria for articles included only measuring local or distal musculoskeletal changes due to BFR training, examining only passive BFR or ischemic preconditioning, articles not originating from a scholarly peer-reviewed journal, CEBM level of evidence less than two, or PEDro score less than four. Articles included in this review were analyzed with the CEBM levels of evidence hierarchy and PEDro scale. Results Thirty-five articles were included in the review. PEDro scores ranged between 4 and 8, and had CEBM levels of evidence of 1 and 2. Common systems studied included cardiovascular, musculoskeletal, endocrine, and psychosocial. This review found positive or neutral effects of blood flow restriction training on cardiovascular, endocrinological, musculoskeletal, and psychosocial outcomes. Conclusions Although BFR prescription parameters and exercise interventions varied, the majority of included articles reported BFR training to produce favorable or non-detrimental effects to the cardiovascular, endocrine, and musculoskeletal systems. This review also found mixed effects on psychosocial outcomes when using BFR. Additionally, this review found no detrimental outcomes directly attributed to blood flow restriction training on the test subjects or outcomes tested. Thus, BFR training may be an effective intervention for patient populations that are unable to perform traditional exercise training with positive effects other than traditional distal muscle hypertrophy and strength and without significant drawbacks to the individual.

Molecular Studies on Probiotic of Human Breast Milk in the Synthesis of Exopolysaccharide (EPS)
The glucosyltransferase (gtf) gene has an important role in exopolysaccharide (EPS) synthesis in probiotic bacteria. The EPS produced is associated with the adhesion ability of bacteria to the intestinal mucosa. Therefore, the gtf gene can be used as a parameter in the selection of potential probiotic through a molecular approach. This study was conducted to determine the presence of the gtf gene in probiotic from human breast milk using PCR technique. The methods in this study include the following: reculture of probiotic isolates, DNA isolation, amplification of the 16S rRNA gene using universal primers (pA and pB), amplification of specific LAB primers (LABfw and LABrv), specific primary design for the gtf gene, and the amplification of the gtf gene. The results of 16S rRNA gene amplification using universal primers obtained the amplicons of 500-1,000 bp in size. The results of amplification using specific LAB primers obtained an amplicon of about 700 bp in all isolates. The results of amplification of the gtf gene using a specific primer produced an amplicon of 325 bp in all isolates. Based on this study, it was concluded that 16 probiotic isolates from human breast milk were proven to have the gtf gene.
Gen glukosiltransferase (gtf) memiliki peran penting dalam sintesis eksopolisakarida (EPS) pada bakteri probiotik. EPS yang diproduksi berhubungan dengan kemampuan adhesi bakteri pada mukosa usus. Oleh karena itu, gen gtf dapat dijadikan sebagai salah satu parameter dalam seleksi probiotik potensial melalui pendekatan molekuler. Penelitian ini dilakukan untuk mengetahui adanya gen gtf pada probiotik asal air susu ibu (ASI) menggunakan teknik PCR. Metode pada penelitian ini meliputi: reculture isolat probiotik, isolasi DNA, amplifikasi gen 16S rRNA menggunakan primer universal (pA dan pB), amplifikasi primer spesifik BAL (LABfw dan LABrv), desain primer spesifik untuk gen gtf dan amplifikasi gen gtf. Hasil amplifikasi gen 16S rRNA menggunakan primer universal diperoleh amplikon berukuran antara 500-1.000 bp. Adapun hasil amplifikasi menggunakan primer spesifik BAL diperoleh amplikon berukuran sekitar 700 bp pada seluruh isolat. Hasil amplifikasi gen gtf menggunakan primer spesifik menghasilkan amplikon berukuran sekitar 325 bp pada seluruh isolat. Berdasarkan penelitian ini dapat disimpulkan bahwa 16 isolat probiotik asal ASI terbukti memiliki gen gtf.

Published: August 2021

Land use change of rubber plantation into ITERA campus area has led to changes in the ecology of the area. Amphibians and reptiles, referred as Herpetofauna, are categorized as wild animals that are sensitive to environmental changes and are considered as bio-indicators. Wild conservation activities including herpetofauna is an essential part to the forest campus concept in ITERA. The objective of the study is to analyze the diversity and distribution of herpetofauna. This applied Visual Encounter Survey (VES) with Time Constraint Method and Glue Trap technique. This research was carried out on six observation path and 180 traps. The ecological index analysis consisted of species diversity, evenness, richness, abundance, and community similarity. Twenty-two herpetofauna species were found, including nine amphibians (5 families) and 13 reptiles (9 families). There was one reptile species with vulnerable conservation status and 3 reptile species included in CITES appendix II. The diversity index value (H ') was 2.29; species evenness (E) value was 0.74; and species richness value was 3.33. Amphibian species with the highest abundance was Fejervarya cancrivora 1.78 individual/hour of observer, while from the reptile species was Hemidactylus frenatus 0.35 individual/hour of observer. There were 550 herpetofauna encounters, where 8 species could be found on all transects and 6 species could only be found on one transect. This research showed that the condition of ITERA habitat currently supported herpetofauna's life and needed conservation activities to maintain herpetofauna diversity.
