SI Dysfunction? Manipulate it, Exercise it, or BOTH

Effectiveness of Exercise Therapy and Manipulation on Sacroiliac Joint Dysfunction: A Randomized Controlled Trial

Nejati P, Safarcherati A, & Karimi F.  Pain Physician. 2019; 22:53-61.

Take Home Message: Overall, exercise and manipulation may provide early improvements for patients with sacroiliac joint dysfunction. However, patients should be re-evaluated before 6 months to determine treatment plans moving forward since the combination of exercise and manipulation was not better than performing exercise or mobilizations alone after 6 months.

Sacroiliac joint dysfunction is a common cause of low back pain.  While exercise is considered to be effective for generalized low back pain, it remains unclear what is the best way to treat low back pain caused by sacroiliac joint dysfunction.  The authors of this study conducted a randomized controlled trial to evaluate the effectiveness of exercise therapy, manipulation therapy, and exercises + manipulation therapy among people with sacroiliac joint dysfunction.

Rest Days are Unrelated with Concussion Rates

National Rugby League Match Scheduling and Rate of Concussion

Gardner AJ, Howell DR, Iverson GL. J Sci Med Sport. 2019 [Epub ahead of print]

Take Home Message: A rugby player was most likely to sustain a concussion during the first rugby match of the year compared with any other match. The number of rest days before a match was unrelated to concussions.,M_1731951.jpg
Rugby athletes are at high risk of suffering a concussion during a match. Over the past 12 years in Australia, the National Rugby League (NRL) added matches on Mondays (beginning of 2007 season) and Thursdays (beginning of 2012) rather than just on weekends. The scheduling changes resulted in fewer rest days during the 24-game season. Additionally, the NRL introduced the “concussion interchange rule” at the beginning of the 2014 season to allow for proper concussion medical care. This rule allows for a brief (up to 15 minutes) sideline concussion evaluation to decide if a player has a concussion and should be removed from play or if not then to return without costing the team one of its 12 player interchanges. No one has studied if the decreased rest time is associated with a higher rate of concussion or was more likely to activate the “concussion interchange rule”. Therefore, the authors sought to determine if there was a relationship between pre-match rest days, match location, time of the season, and match outcome with diagnosed concussion and use of the “concussion interchange rule”.

Parents are Open to Age Restrictions for Tackling in Football

Parents’ Perspectives Regarding Age Restriction for Tackling in Youth Football

Take Home Message: In the United States, the majority of parents (61%) support a minimum age for tackling in football. An additional 24% indicated that they would “maybe” support such an age limit.

In recent years, there have been increasing concerns about the acute and chronic effects of concussive and sub-concussive head impacts that occur during sports. Some sport organizations like US Soccer and USA Hockey have recently implemented age restrictions on heading and checking respectively with marked success with reducing injury in the latter. Despite football being the most popular youth sport for boys, no such age restriction exists for tackling. Furthermore, it is unclear if the public would support such restrictions if they were imposed. Therefore, Chrisman and colleagues surveyed a nationally representative sample of parents with school-aged children to determine the level of national support present for age restrictions on tackling.

Load, Overload, and Recovery in the Athlete: Select Issues for the Team Physician-A Consensus Statement

Load, Overload, and Recovery in the Athlete: Select Issues for the Team Physician-A Consensus Statement.

Med Sci Sports Exerc. 2019 Apr;51(4):821-828. doi: 10.1249/MSS.0000000000001910.

The American Academy of Family Physicians, the American Academy of Orthopaedic Surgeons, the American College of Sports, Medicine, the American Medical Society for Sports Medicine, the American Orthopaedic Society for Sports Medicine, and the American Osteopathic Academy of Sports Medicine collaborated to develop a statement on load, overload, and recovery in the athlete. “This document provides an overview of the concepts of load, overload, and recovery, as well as the musculoskeletal and psychosocial issues related to overload injuries and illnesses that are important for the team physician to understand. In addition, understanding the role of wearable devices, technology, and other tools used to measure load, overload, and recovery is important.” The document also addresses intervention strategies.

Manual Therapy after Ankle Surgery: Do or Don’t?

Short-Term Effects of Manual Therapy in Patients After Surgical Fixation of Ankle and/or Hindfoot Fracture: A Randomized Clinical Trial

Albin SR, Koppenhaver SL, Marcus R, Dibble L, Cornwall M, Fritz JM. J Orthop Sports Phys Ther. 2019. doi: 10.2519/jospt.2019.8864. [Epub ahead of print]

Take Home Message: After surgical fixation of an ankle/hindfoot fracture, people who received joint mobilizations during 3 sessions had similar improvements in ankle range of motion, balance, and gait compared to people receiving only light soft-tissue mobilization.

Patients with fractures to the ankle/hindfoot commonly undergo operative fixation. These patients often experience post-operative deficits in range of motion and balance as well as gait alterations that increase the risk for long-term consequences if not fully addressed during rehabilitation. Typical post-surgical treatment requires long periods of immobilization that results in talocrural and subtalar joint stiffness. Unfortunately, only 1 in 5 patients will be able to fully recover from the increased stiffness. Manual therapy may improve outcomes after surgical fixation but there is little evidence to support this hypothesis. Thus, the authors conducted a randomized controlled trial to determine the short-term effects of manual therapy on ankle and foot mobility, muscle stiffness, gait, and static and dynamic balance.

AMSSM Position Statement Update: Blood-Borne Pathogens in the Context of Sports Participation

AMSSM Position Statement Update: Blood-Borne Pathogens in the Context of Sports Participation.

McGrew C, MacCallum DS, Narducci D, Nuti R, Calabrese L, Dimeff R, Paul S, Poddar SK, Rao A, McKeag D. Clin J Sport Med. 2019 Mar 20. doi: 10.1097/JSM.0000000000000738. [Epub ahead of print]

The American Medical Society for Sports Medicine (AMSSM) updated a position statement on blood-borne pathogens in the context of sports participation. The document is directed toward all health care providers who care for patients involved in sport or exercise. The document reviews relevant epidemiology, testing/screening, specific management and preventive measures, effects of exercise on athletes living with blood-borne pathogens and general principles of management, and education.
