Strength of the Uninvolved Limb Following Return to Activity After ACL Injury: Implications for Symmetry as a Marker of Sufficient Strength
Authors: Hartshorne Matthew T , Turner Jeffrey A , Cameron Kenneth L , Padua Darin A
Published: June 2024

Background

Muscular strength deficits are common after ACL injury. While the Limb Symmetry Index (LSI), using the uninvolved limb as a reference, is widely used, negative strength adaptations may affect both limbs post-injury. It is uncertain how the strength of the uninvolved limb in those with an ACL injury compares to uninjured individuals, making it unclear whether it is appropriate as a benchmark for determining sufficient strength.

Purpose

To compare the strength of key lower extremity muscles of the uninvolved limb in those with history of ACL injury (ACL-I) to the dominant limb in individuals with no history of ACL injury (control).

Study Design

Cross-sectional study.

Methods: A total of 5,727 military cadets were examined, with 82 females and 126 males in the ACL-I group and 2,146 females and 3,373 males in the control group. Maximum isometric strength was assessed for six muscle groups measured with a hand-held dynamometer. Separate two-way ANOVAs with limb and sex were performed for each muscle group.

Results

Significant main effects for limb were observed with the uninvolved limb in the ACL-I group displaying greater strength compared to the dominant limb in the control group for the quadriceps, hamstrings, and gluteus medius, but effect sizes were small (Cohen’s d <0.25). Significant main effects for sex were observed with greater male muscular strength in all six muscle groups with small to large effect sizes (Cohen’s d 0.49-1.46). No limb-by-sex interactions were observed.

Conclusions

There was no evidence of reduced strength in the uninvolved limb in those with a history of ACL injury compared to the dominant limb in those with no prior ACL injury. This finding suggests that, after clearance to return to activities, the uninvolved limb can be used as a standard for comparison of sufficient strength, including when using the LSI.

Effects of Low-Load Blood Flow Restriction Training on Rotator Cuff Strength and Hypertrophy: Case Series
Authors: Safford Daniel W , Shah Kshamata M , Breidenbach Frederic , McClure Philip W
Published: June 2024

Background

The rotator cuff (RC) plays a pivotal role in the performance and health of the shoulder and upper extremity. Blood flow restriction training (BFRT) is a modality to improve strength and muscle hypertrophy with even low-load training in healthy and injured individuals. There is minimal evidence examining its effect proximal to the occluded area, and particularly on the RC.

Hypothesis & Purpose

The purpose of this case series is to explore the effects of low-load BFRT on RC strength, hypertrophy, and tendon thickness in asymptomatic individuals.

Study Design

Case series.

Methods

Fourteen participants with asymptomatic, untrained shoulders were recruited to participate. They performed an eight-week low-load shoulder exercise regimen where BFR was applied to the dominant arm only during exercise. The dependent variables were maximal isometric strength of the shoulder external rotators(ER) and elevators (in the scapular plane in full can position) (FC) measured via handheld dynamometry, cross sectional area (CSA) of the supraspinatus and infraspinatus muscles, and supraspinatus tendon thickness measured via ultrasound imaging (US). Mean changes within and between arms were compared after training using paired t-tests. Cohen’s d was used to determine effect sizes.

Results

All participants were able to complete the BFRT regimen without adverse effects. Mean strength and CSA increased for all variables in both arms, however this increase was only significant (p<0.01) for FC strength bilaterally and CSA for the supraspinatus and infraspinatus on the BFRT side. The effect sizes for increased supraspinatus and infraspinatus CSA on the BFRT side were 0.40 (9.8% increase) and 0.46 (11.7% increase) respectively. There were no significant differences when comparing the mean changes of the BFRT side to the non-BFRT side for strength or muscle CSA. There were no significant changes to supraspinatus tendon thickness.

Conclusion

These results suggest variability in response of the RC musculature to low-load BFRT in asymptomatic individuals. The potential for a confounding systemic response in the study design makes determining whether low-load BFRT is more beneficial than low-load non-BFRT difficult. The hypertrophy seen on the BFRT side warrants further study.

Pain Neuroscience Education for Acute Pain
Authors: Louw Adriaan , Schuemann Teresa , Zimney Kory , Puentedura Emilio J
Published: June 2024

In musculoskeletal and sports medicine, pain has traditionally been linked to tissue injury, often assuming a linear correlation between tissue damage and pain intensity. However, modern pain science has illuminated the complexity of the human pain experience, incorporating psychosocial elements, nervous system sensitization, immune responses, and structural changes in the brain as factors. This contemporary understanding of pain has proven highly beneficial for both clinicians treating individuals in pain and those experiencing pain.

Pain neuroscience education (PNE) provides individuals in pain with an understanding of the underlying neurobiology and neurophysiology of their pain experience, which has been shown to result in decreased self-reported pain, reduced disability, the alleviation of fear and fear-avoidance behaviors, diminished pain catastrophizing, and improved movement. Currently, research on PNE predominantly focuses on interventions with individuals with persistent or chronic pain conditions. However, those who experience acute, sub-acute, and perioperative pain also have the potential for elevated levels of fear, fear-avoidance, and pain catastrophizing, indicating potential benefits from PNE.

This invited commentary seeks to inform readers about the latest advancements in pain science and propose a conceptual model for delivering PNE in acute pain experiences.

ERROR ANALYSIS OF THE SOLUTIONS OF (1+1)- DIMENSIONAL & (2+1)-DIMENSIONAL HEAT-LIKE EQUATIONS USING HE’S POLYNOMIAL
Authors: Kaur Mankirat
Published: June 2024

In this paper, we are examining He’s polynomial method for solving (1+1)- dimensional and (2+1)-dimensional heat-like equations that arise in various diffusion processes. The absolute error is calculated from the exact solution and numerical solution by taking different iterations of the He’s polynomial. This method is also called the homotopy perturbation method (HPM). The nonlinear terms can be easily handled by the use of He’s polynomials. The proposed scheme finds the solution without any discretization or restrictive assumptions and avoids round-off errors. Some examples are given to show the efficiency and accuracy of the He’s polynomial used to solve Heat-like equations.

Published: June 2024

Spray drying is one of the most preferred preservation methods that converts an aqueous feed containing solvent, carrier agent, and food compounds into dry powder with superb physicochemical and functional properties. This paper reviews the fundamental and important operating parameters, product characteristics, current and potential applications, and techno-economic aspects of spray drying. The key operating parameters should be chosen to achieve the highest spray drying performance in terms of operational efficiency and product quality. A successful spray drying operation is greatly dependent on the feed material properties, the mechanical design of the equipment, and selected operating parameters. This paper also found that water content, water activity, and glass transition temperature are the main parameters that really determine product quality in terms of shelf life and storage conditions of food powder obtained from the spray drying process. Recent advances in the development of new heatless spray drying technology in the manufacture of food flavoring and nutraceuticals are interesting to develop, in addition to the potential to produce nano-sized powders with distinctive properties and the use of superheated steam and carbon dioxide to sterilize products. The appropriate information on spray drying technology featured in this paper is targeted to reinforce researcher and practitioner understanding for widening its applications in pertinent food industries. Doi: 10.28991/HEF-2024-05-02-09 Full Text: PDF

This research was conducted to analyze the need for developing learning tools based on religious moderation in schools in conflict-prone areas in West Nusa Tenggara. This qualitative research uses a document analysis and narrative analysis approach. The research subjects were 20 people from conflict-prone areas in West Nusa Tenggara who were taken using a purposive sampling technique. Data was collected using documentation techniques, focus group discussions and in-depth interviews. Data from document analysis was interpreted using the thematic analysis method and FGD data was analyzed using narrative analysis to obtain conclusions regarding the need for developing learning tools based on religious moderation in schools in conflict-prone areas. The research results show that science learning tools in junior high schools in conflict-prone areas do not fully contain the value of religious moderation. Science learning tools for students in conflict-prone areas require explicit elements of moderation. Elements of religious moderation are needed in learning planning documents and textbook documents. The learning planning needed creates an inclusive learning environment, encourages cooperation, develops character values, increases religious understanding, and strengthens student character formation. The required teaching materials contain descriptions that provide a broad understanding of moderation, promote spiritual values, and assist students in character development.
