Outpatient Physical Therapy Management of a Patient with Right Hamstring Strain Injury: A Case Report

Background and Purpose: Hamstring injuries are the most common muscle strains in competitive sports. Insufficient rehabilitation may be attributed to a high occurrence of recurrent hamstring injuries in athletes. This case study evaluates the effectiveness of physical therapy following a Grade 2 right hamstring injury and discusses the outcomes experienced by the patient. Case Description: The patient was a 51-year-old Caucasian female athlete who received 6 outpatient physical therapy treatments. She presented with a Grade 2 right hamstring injury after hearing a pop while competing in a tennis tournament. Interventions: The therapy provided emphasized the use of a conservative approach with functional exercises including eccentric hamstring loading. The exercises were used in conjunction with FIFA 11+ with dynamic activities to assist the patient to return to sport at the same level of performance she had prior to the injury. Outcomes: Over the course of treatment, the patient was able to increase her functional ability with squatting, bending, running, hiking, sitting, and tennis while decreasing her pain. Discussion: The patient responded favorably to treatment and her goals in her plan of care were met. However, more research must be done on the assessment, rehabilitation, and education of female tennis players with hamstring injuries

Split-beam sonars: a backscatter model and prototype data analysis

Split-beam echosounders provide estimation of fish size by directly measuring their target strength. A model that can be used to evaluate and optimize split-beam sonar performance is presented. The model has been used to generate beam patterns to match prototype instruments and to simulate acoustic signals based on the scattering of sound from particles in a three-dimensional domain. The sum of the contribution of the scatterers is sampled at the transducer locations, resulting in simulated signals used for data processing and sonar performance prediction. The model’s capabilities were evaluated through comparisons with ASL Environmental Sciences’ AZFP-Split prototype system. The field trials were conducted in Saanichton, BC, by lowering a calibration target sphere to a range of 220 m in the acoustic beam. Both model prediction and prototype system performance show accuracy of σ = 0.2 dB at 25 m range. Potential future applications of the model include exploring methods of target separation and improving accuracy when presented with complex target structures

Toolkit: Healing our protectors: Building resilience among tribal law enforcement officers through cultural interventions

Introduction: The U.S. and Native Americans have a government-to-government relationship. The result of 375 treaties, established laws and instituted policies promote Tribal sovereignty and are intended to support the general wellbeing Indigenous persons and protect their lands and resources. The Tribal sovereignty includes law enforcement. This resource is intended to provide a broad understanding of the challenges both Tribal and Bureau of Indian Affairs (BIA) law enforcement officers face; many struggle dealing with the traumatic events they have experienced. We acknowledge that there is a scarcity of current information related to Tribal and BIA police officers’ mental health. This document is in response to that concern. In this product we present statistics on tribal and BIA law enforcement officers when and where data are available. We provide resources and strategies that focus on knowledge and skills development to build resilience and wellness among our protectors. Most importantly, this resource provides a review of stress through the narrative of the author Leo Belgarde, Sr. Leo was forced to retire from law enforcement due to posttraumatic stress disorder (PTSD). This resource shares Leo’s story and provides suggestions for treatment and prevention using culturally responsive practices for providers of behavioral health treatment. The authors and contributors suggest using this content in training programs to underscore the realities and impact of stress with suggestions for both organizational and individual response. PTSD and historical, intergenerational, and transgenerational trauma will be reviewed. Audience: This resource is intended to assist behavioral health providers in gaining a greater understanding of post-traumatic stress disorder (PTSD) among law enforcement officers, especially those working in and with tribal communities. It provides suggestions for a culturally responsive approach to treatment using the medicine wheel, and offers concrete exercises. It is also a tool for law enforcement supervisors and administrators who wish to gain a greater understanding of the unique needs of Indigenous law enforcement officers who are dealing with a host of job related challenges and stressors

Racial Misclassification of American Indian and Alaskan Natives on Death Certificates in the United States: Report for National Network of Public Health Institutes.

Racial misclassification is a persistent issue among American Indian and Alaskan Natives who are grossly misrepresented in death. Training is needed for those who report race on death certificates (i.e., funeral directors) so that health and mortality data is accurately reported. An environmental scan of existing resources, literature, and training opportunities was completed in order to understand the current knowledge as well as gaps in racial reporting on death certificates. Racial misclassification is a major barrier to accurate health data for AI/AN populations. It is estimated that approximately 20% of sampled AI/AN individuals were misclassified on their death certificates. Additionally there is a significant lack of tribe specific reporting for AI/AN individuals

Southern San Andreas-San Jacinto fault system slip rates estimated from earthquake cycle models constrained by GPS and interferometric synthetic aperture radar observations

We use ground geodetic and interferometric synthetic aperture radar satellite observations across the southern San Andreas (SAF)-San Jacinto (SJF) fault systems to constrain their slip rates and the viscosity structure of the lower crust and upper mantle on the basis of periodic earthquake cycle, Maxwell viscoelastic, finite element models. Key questions for this system are the SAF and SJF slip rates, the slip partitioning between the two main branches of the SJF, and the dip of the SAF. The best-fitting models generally have a high-viscosity lower crust (η = 10^(21) Pa s) overlying a lower-viscosity upper mantle (η = 10^(19) Pa s). We find considerable trade-offs between the relative time into the current earthquake cycle of the San Jacinto fault and the upper mantle viscosity. With reasonable assumptions for the relative time in the earthquake cycle, the partition of slip is fairly robust at around 24–26 mm/a for the San Jacinto fault system and 16–18 mm/a for the San Andreas fault. Models for two subprofiles across the SAF-SJF systems suggest that slip may transfer from the western (Coyote Creek) branch to the eastern (Clark-Superstition hills) branch of the SJF from NW to SE. Across the entire system our best-fitting model gives slip rates of 2 ± 3, 12 ± 9, 12 ± 9, and 17 ± 3 mm/a for the Elsinore, Coyote Creek, Clark, and San Andreas faults, respectively, where the large uncertainties in the slip rates for the SJF branches reflect the large uncertainty in the slip rate partitioning within the SJF system

Thermoelectrics with Applications to Waste Heat Recovery, Heat Sources, and HVAC Systems

When certain materials are joined at their junctions with dissimilar materials, and they generate a flow of electricity when a thermal gradient is acted upon between the junctions is familiarly known as the Seebeck Effect. This effect may be reversed, also known as the Peltier Effect, which is the distinctive ability to create a temperature variance while an electrical potential difference is applied among these junctions. With the world’s stride to create a more efficient and clean environment, one must render technologies based on development of power extracted from waste heat, and the lack of emissions due to Peltier Cooling and Heating Systems. This review paper talks about the research done to optimize the performance of systems relating to heat sources and waste heat, as well as propose solutions to current issues pertaining to the energy crises. Thermoelectrics will be considered as the foundation to erect a new efficient and environmentally safe planet
