Context: Hamstring inflexibility is typically treated using therapeutic massage, stretching, and soft tissue mobilization. An alternative intervention is deep oscillation therapy (DOT). Currently, there is a lack of evidence to support DOT’s effectiveness to improve flexibility. Objective: To explore the effectiveness of DOT to improve hamstring flexibility. Design: Randomized single-cohort design. Setting: Research laboratory. Participants: Twenty-nine healthy, physically active individuals (self-reported activity of a minimum 200 min/wk). Interventions: All participants received a single session of DOT with randomization of the participant’s leg for the intervention. The DOT intervention parameters included a 1∶1 mode and 70% to 80% dosage at various frequencies for 28 minutes. Hamstring flexibility was assessed using passive straight leg raise for hip flexion using a digital inclinometer. Patient-reported outcomes were evaluated using the Copenhagen Hip and Groin Outcome Score and the Global Rating of Change (GRoC). Main Outcome Measure: The independent variable was time (pre and post). The dependent variables included passive straight leg raise, the GRoC, and the participant’s perceptions of the intervention. Statistical analyses included a dependent t test and a Pearson correlation. Results: Participants reported no issues with sport, activities of daily living, or quality of life prior to beginning the intervention study on the Copenhagen Hip and Groin Outcome Score. Passive straight leg raise significantly improved post-DOT (95% confidence interval, 4.48°–7.85°, P < .001) with a mean difference of 6.17 ± 4.42° (pre-DOT = 75.43 ± 21.82° and post-DOT = 81.60 ± 23.17°). A significant moderate positive correlation was identified (r = .439, P = .02) among all participants between the GRoC and the mean change score of hamstring flexibility. Participants believed that the intervention improved their hamstring flexibility (5.41 ± 1.02 points) and was relaxing (6.21 ± 0.86). Conclusions: DOT is an effective intervention to increase hamstring flexibility.

An 18-year-old, male collegiate basketball athlete complained of right testicular pain following basketball activities. The patient’s imaging denoted edema within the pubis at the insertion of the adductor longus tendon and rectus sheath aponeurosis consistent with inguinal disruption. The patient underwent conservative rehabilitation and attempted to return to participation with increased pain. Subsequently, the patient underwent surgery. Following surgical intervention, the patient underwent 6 weeks of rehabilitation with basketball-specific considerations. On conclusion, the patient was pain free and returned to activity. This case is unique due to the insidious onset, sport in which the patient participated, and failed conservative management.

The management of an acute lateral ankle sprain (LAS) affects long-term outcomes, which highlights the need for assessment of practice at the point of care. The purpose of this retrospective chart review was to examine the management strategies for acute LAS as documented in a secondary school’s electronic medical records (EMR) over 2 years. Patient charts noting a LAS diagnosis (n = 107) were identified from the EMR. Most charts indicated palpation and anterior drawer test performance. Cryotherapy (82%) and compression (55%) varied in use. Therapeutic rehabilitation and return-to-activity testing were underreported. Overall, clinical management of acute LAS may not align with best available evidence.

Firefighters are exposed to psychological stress while on duty that could lead to mental and behavioral illnesses that may go unreported. We surveyed firefighters to identify their perceived barriers encountered when attempting to report a mental and behavioral illness with a follow-up question related to how difficult the selected barrier was in the reporting process. A total of 314 firefighters completed the instrument, with most indicating they experienced cultural barriers such as social norms from administration and peers. The findings demonstrate an overall demand for a cultural change within the fire service for a supportive environment that encourages reporting.
