A Targeted Approach to Evaluating the Golfing Athlete with Low Back Pain: A Resident’s Case Report
Authors: Deckard Luke 
Published: June 2021

Background and Purpose Low back pain is one of the most common conditions occurring in the golfing population. Many approaches have been utilized throughout the years to address this condition including the concept of regional interdependence. The purpose of this case report is to describe the evaluation process and treatment approach of a golfer with low back pain using the principles of regional interdependence. Case Description A thirty-year-old male with right-sided low back pain was evaluated using a comprehensive approach including golf specific movement screening and a swing evaluation. The patient had mobility restrictions in his thoracic spine and hips that appeared to be contributing to a hypermobility in the lower lumbar spine. Based on the evaluation, he was placed into the treatment-based classification (TBC) of stabilization but would also benefit from mobilization/manipulation techniques. Outcomes After seven visits over a four-week span, the patient’s mobility and core stability both improved and he was able to play golf and workout pain free. His outcome measures also improved, including the revised Oswestry Disability index from 26% disabled to 10%, the Fear Avoidance Behavior Questionnaire (FABQ) Work from 10/42 to 3/42, and the FABQ Physical Activity from 19/24 to 6/24. Discussion Evaluating and developing a plan of care to address low back pain in an avid golfer can be challenging as a variety of demands are placed on the spine during the movement. This case report describes the evaluation process and treatment approach to specifically target the demands that are required during the golf swing. Utilizing a targeted approach that includes golf specific movement screening and a swing evaluation can help guide the therapist in their treatment and improve the patient’s outcome.

Published: June 2021

Background Mechanical percussion devices have become popular among sports medicine professionals. These devices provide a similar effect as manual percussion or tapotement used in therapeutic massage. To date, there are few published studies or evidence-based guidelines for these devices. There is a need to understand what professionals believe about this technology and how they use these devices in clinical practice. Purpose To survey and document the knowledge, clinical application methods, and use of mechanical percussion devices among healthcare professionals in the United States. Design Cross-sectional survey study. Methods A 25 question online survey was emailed to members of the National Athletic Trainers Association, Academy of Orthopedic Physical Therapy, and American Academy of Sports Physical Therapy. Results Four hundred twenty-five professionals completed the survey. Most professionals (92%, n=391) used devices from two manufacturers: Hyperice® and Theragun®. Seventy-seven percent directed clients to manufacturer and generic websites (n=329) to purchase devices. Most respondents used a medium and low device speed setting for pre- and post-exercise (62%, n=185), pain modulation (59%, n=253), and myofascial mobility (52%, n=222). A large proportion of respondents preferred a total treatment time between 30 seconds and three minutes (36-48%, n=153-204) or three to five minutes (18-22%, n=76-93). Most respondents (54-69%, n=229-293) believed that mechanical percussion increases local blood flow, modulates pain, enhances myofascial mobility, and reduces myofascial restrictions. Most respondents (72%, n=305) were influenced by other colleagues to use these devices. Sixty-six percent used patient reported outcomes (n=280) to document treatment efficacy. Live instruction was the most common mode of education (79%, n=334). Conclusion These results are a starting point for future research and provide insight into how professionals use mechanical percussion devices. This survey also highlights the existing gap between research and practice. Future research should examine the efficacy of this technology and determine consensus-based guidelines.

The Neuroplastic Adaptation Trident Model: A Suggested Novel Framework for ACL Rehabilitation
Authors: Machan Timothy , Krupps Kody 
Published: June 2021

Anterior Cruciate Ligament (ACL) injuries are common in athletic populations and there are many factors that contribute to a return to play decision. Human movement is diverse and variable, and it is important for patients recovering from an ACL injury to develop a variety of movement strategies for athletic performance. Variability of movement during sport may help to decrease injury risk by preparing the individual to handle many different situations and improve problem solving. ACL injuries result in neurophysiological dysfunction due to a disruption of the afferent information from the native mechanoreceptors in the ligament. Following injury, the brain enters a neuroplastic state and can adapt and change positively or negatively based on the rehabilitation or lack thereof. This commentary presents a novel framework for rehabilitation called the Neuroplastic Adaptation Trident Model that takes into account respected methods for attempting to achieve positive neuroplastic changes. This structured framework provides clinicians with reproducible methods to employ as part of the rehabilitation process to maximize motor control and motor learning. Suggested dosage and implementation are proposed to lead to a consistent and gradually progressive challenge throughout the entire rehabilitation process that takes advantage of the time from surgery until return to play. The purpose of this clinical commentary is to describe the Neuroplastic Adaptation Trident model and provide examples for clinical implementation. This method should be studied further to determine true effectiveness; currently, it is presented as a theoretical model based on best current evidence regarding ACL injury and rehabilitation of neurophysiologic dysfunction.

Published: June 2021

Background Flossing includes wrapping a specialized latex band around a muscle group providing compression, partially occluding blood flow, followed by performing exercises. This is hypothesized to improve flexibility by dissipating myofascial adhesions; however, research is lacking. Objective To determine the effect of the application of a floss band to the thigh on hamstring flexibility and lower extremity power. Design Crossover Study Setting Exercise Physiology Laboratory. Participants Twenty-one recreationally active individuals (8 male, 13 female; age = 22.62±2.99 years; height = 171.52±9.08 cm; mass = 73.57±11.37 kg). Methods Three counterbalanced interventions were studied during body weight squats, lunges, and hamstring curls (without resistance): floss, sham, and control. The floss treatment included wrapping the Rogue Wide Voodoo Floss Band™ from the proximal knee to the gluteal fold at a pressure of 140 to 200 mmHg. The sham treatment included wrapping the same band in the same location with less pressure (10 to 40 mmHg) while the control treatment did not include floss band application. Hip flexion range of motion, via the straight leg raise, and power (single-leg vertical jump) were compared from pre-test to post-test using a 3x2 repeated measures ANOVA. Results There was a significant interaction between time and session for hamstring flexibility (F(2,40)=17.54, p<0.001, η2=0.47). Post hoc tests showed significant differences between pre- (86.14±8.06 degrees) and post-test (90.81±7.69 degrees) for the floss session (p<0.001, Mean Difference=4.67, CI95=3.35-5.98) and between pre- (87.67±7.51 degrees) and post-test (89.86±7.88 degrees) for the sham session (p=0.001, Mean Difference=2.19, CI95=0.98-3.40). There were no significant interactions for jump power (F(2,40)=1.82, P=0.18, η2=0.08, 1-β=0.36). Conclusions Flossing treatment increased hamstring flexibility more than the sham session without affecting lower body power. Flossing could be beneficial when treatment or performance preparation goals are increased flexibility without decreased power. Future studies should continue to examine the clinical effectiveness of flossing on an injured population.

Authors: Kemp Jordyn A , Olson Megan A , Tao Matthew A , Burcal Christopher J 
Published: June 2021

Background Lateral epicondylitis (LE) is one of the most commonly reported musculoskeletal disorders in the upper extremity. The mechanism of LE is repetitive motion that causes a strain of the extensor tendons. This consequently causes pain and tendinosis at the tendinous attachment site on the lateral epicondyle. Most cases of LE are treated nonoperatively with a variety of interventions, such as injections. Purpose The aim of this systematic review (SR) is to synthesize the current evidence on the efficacy of platelet rich plasma (PRP) injections versus corticosteroid (CS) injections as treatment interventions for LE. Study Design Systematic Review Methods Online databases were searched from database inception to February 24th, 2020 for relevant SR’s evaluating PRP vs. CS injections as treatment methods for LE. Two independent researchers searched and screened for articles that were systematic reviews that directly compared PRP to CS injections for LE. Results A total of five SR’s were included in this review that were published between 2016 and 2020. CS injections were more efficacious for short-term pain relief, and PRP injections were more efficacious for long-term pain relief and improved function. Conclusion PRP injections appear to be a more effective long-term treatment option than CS injections for those with LE who did not respond to conservative management. Level of evidence 1

Published: June 2021

Background Limited research exists on the effects of both high and low frequency whole body vibration (WBV) on individuals with subacute lateral ankle sprains. Hypothesis/Purpose To examine the difference in the effects of high and low frequency WBV on limits of stability (LOS) in adults with a subacute ankle sprain. It was hypothesized that WBV would improve effects on outcome variables for LOS as a component of dynamic balance. Study Design Quasi-experimental, pretest-posttest design. Methods Fifteen participants ages 19-27 years (Mean age 22±2.36) with either a Grade I or Grade II lateral ankle sprain received WBV in bilateral stance under three randomized conditions (high frequency-25 Hz, low frequency-6 Hz, and control, which consisted of bilateral stance with machine off) for six minutes over three sessions (one time per week). The LOS test, consisting of 5 variables, were assessed using the NeuroCom® Balance Manager-SMART EquiTest® (Natus Medical Incorporated, Pleasanton, CA) at baseline and after the intervention period. The participants completed a practice LOS test and then had a six-minute standing rest break. After the rest break, they completed the pre-LOS (baseline) test. Intervention was administered using the Galileo® Med L Chip Research (Novotec Medical GmbH, Pforzheim, Germany) for six minutes for the appropriate condition of either high or low frequency WBV or control. Data analysis was performed using 2-Way (2x3) Repeated Measures ANOVAs with additional post hoc testing as needed. Results Significant interactions were found for reaction time (RT), movement velocity (MVL), and maximal excursion (MXE) composite scores with a decrease in RT of 0.117 seconds (p=0.022) between control and high frequency conditions during the post LOS. For composite MVL, an increase of 0.547 degrees/second (p=0.002) between pre- and post-high frequency WBV occurred. For composite MXE, an increase of 2.13% p=0.031 (when comparing pre- and post-high frequency WBV. Conclusion Findings suggest that a single session of high frequency WBV in individuals with a subacute lateral ankle sprain may result in improvement in several components of postural stability. WBV is a quick intervention that could be implemented in physical therapy clinics, athletic training rooms, and workout facilities to improve an individual’s LOS as a component of dynamic balance one to eight weeks post lateral ankle sprain.

Synthesis of a seven-link statically determined spatial hinge mechanism with an additional movable crank link without redundant (passive) connection of the tumbling machine with a complex spatial movement of the working vessel with subsequent analytical study of its design and geometric parameters. Methodology. The analytical method of research is used on the basis of geometric and structural synthesis of a spatial seven-link hinge mechanism with an additional movable crank link without redundant connection of the tumbling machine with a complex spatial movement of the working vessel. The machine was simulated in the SolidWorks-2016 computer-aided design system. Tumbling types of equipment with containers, which perform a different character of movement, are analyzed. On the basis of structural synthesis, the design of a seven-link statically defined spatial mechanism with an additional movable link, a tumbling machine crank, in which the working capacity performs a complex spatial movement, is proposed. Carried out 3D modeling of the machine in the CAD system SolidWorks 2016. Analytical studies of the main geometric parameters of the developed tumbling machine were carried out. Scientific novelty. A relationship has been established between various geometric parameters of the synthesized seven-link statically determined spatial hinge mechanism, in particular, between the center-to-center length of the intermediate connecting rod (working capacity) and the length of the crank, which makes it possible to calculate the necessary ratios of the lengths of the links of the mechanism to ensure the functioning of the machine without jamming its spatial mechanism. Practical significance. A new design of a machine for processing parts has been developed, based on a seven-link statically determined spatial hinge mechanism with an additional movable crank link. Mathematical dependences are obtained for calculating its basic design and geometric parameters. These dependencies can be used in the corresponding design bureaus of machine-building enterprises at the design stage of tumbling equipment with a complex spatial movement of working containers.
