Concussion-related visual memory and reaction time impairment in college athletes improved after osteopathic manipulative medicine: a randomized clinical trial.

CONTEXT: Concussion is an acute, transient disruption in brain function due to head injury. Previous studies suggest osteopathic manipulative medicine (OMM) improved recovery from concussion. OBJECTIVES: The hypothesis was that new-onset impairments (NOI) of neurological functions identified by Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) will improve more so after OMM than after concussion-education. METHODS: College athletes presenting to the outpatient academic healthcare center (AHCC) with concussion due to head injury within the preceding 2 weeks were recruited for this IRB-approved, randomized, single-blinded trial. Consented men and women were randomized into groups receiving two OMM treatments or two concussion-education sessions to control for social effects. Preseason, Baseline, ImPACT was compared to Post-Injury scores to determine NOI. Baseline, Post-Injury, and Post-Interventions ImPACTs were compared by analysis of variance (ANOVA, α≤0.05). Post-Injury correlations and mean changes in King-Devick (KD) scores were analyzed. RESULTS: Post-Injury NOI were found in 77.8% (14/18) men and 85.7% (6/7) women, including ImPACT subscore indices for verbal and visual memory, processing speed (PS), and reaction time (RT). Of those with NOI, mean visual memory recovered by 50.0% following one and by 104.9% (p=0.032) following two OMM treatments in men and by 82.8% (p=0.046) following one treatment in women. Following two interventions, the mean RT in men receiving OMM improved by 0.10 more than education (p=0.0496). The effect sizes of OMM were large (Cohen's d=1.33) on visual memory and small (Cohen's d=0.31) on RT. CONCLUSIONS: The NOI in visual memory and RT following concussion significantly improved in the OMM group compared to the education group. Integrating OMM utilizing physical exam and this treatment was a safe individualized approach in athletes with acute uncomplicated concussions. Further research is warranted to improve the utilization of OMM for individuals with concussion.

Effects of Osteopathic Manipulative Treatment on Sleep Quality in Student Athletes After Concussion: A Pilot Study.

CONTEXT: Impaired sleep quality is among many symptoms observed in patients with a concussion and may predispose a patient to a prolonged recovery course and a later return to their daily activities. Studies have suggested that osteopathic manipulative treatment (OMT) may play a role in improving sleep quality. OBJECTIVE: To investigate how OMT may play a role in the management and overall healing process in patients with a concussion by improving sleep quality. METHODS: Data were collected from a randomized, controlled study on OMT and concussion (of which this study represents 1 arm) to investigate the effects of OMT vs concussion education counseling on sleep quality in student athletes with a concussion. Student athletes with no medical history of neurodegenerative disease who presented to the New York Institute of Technology College of Osteopathic Medicine Academic Healthcare Center with a concussion following a sport-related injury were enrolled in the study. Participants received OMT intervention or standard counseling on how to care for a concussion during their first and second visits. Participants rated their symptoms, including sleep quality, on the validated scale Sport Concussion Assessment Tool 5th Edition at 3 consecutive visits during 1 week. The mean sleep quality score within and between the OMT and education groups before each of 2 interventions and at the third visit were compared and analyzed using the Mann-Whitney U test. RESULTS: Thirty participants were enrolled in the study. Total symptom data showed a stronger, significant correlation with sleep scores than with other symptoms. Participants receiving OMT (n=16) reported overall 80% and 76% improvement in sleep quality from pre-OMT values to their second and third visits, respectively. Participants who had an educational intervention (n=14) reported a 36% and 46% improvement from pre-OMT values to their second and third visits, respectively. CONCLUSION: The beneficial relationship trend between OMT and sleep quality in patients with a concussion was not statistically significant. Owing to the limitations of this study, further research with a larger population and sham control participants is warranted. (clinicaltrials.gov No. NCT02750566).

Effectiveness of Osteopathic Manipulative Medicine vs Concussion Education in Treating Student Athletes With Acute Concussion Symptoms.

CONTEXT: Concussion, a type of mild traumatic brain injury, is a disruption in normal brain function due to head injury. New-onset symptoms from concussion vary, likely depending on the areas of the head and neck affected; they can be severe and debilitating. Current treatment options are limited and difficult to individualize. Osteopathic manipulative medicine (OMM) can aid musculoskeletal restrictions that can potentially improve concussion symptoms. OBJECTIVE: To assess concussion symptom number and severity in participants with concussion who received either OMM or an educational intervention. METHODS: A randomized controlled trial was conducted at the New York Institute of Technology Academic Health Care Center. Patients presenting to the center with concussion-like symptoms due to recent head injury within the previous 7 days provided consent and were randomized into 2 intervention groups, receiving either 1 OMM treatment (n=16) or 1 concussion education intervention (n=15). Participants were assessed before and after the intervention with the validated Symptom Concussion Assessment Tool fifth edition (SCAT-5) for quantification of number of symptoms and their severity. Collected data were analyzed using the Mann-Whitney U test and the repeated-measures analysis of variance. RESULTS: Thirty-one participants were enrolled in the study; after 1 control participant was excluded due to incomplete data, 30 patient records were analyzed. The OMM intervention group had a significant decrease in symptom number (P=.002) and symptom severity (P=.001) compared with the concussion education group. CONCLUSION: When used in the acute setting, OMM significantly decreased concussion symptom number and severity compared with concussion education. This study demonstrates that integration of OMM using a physical examination-guided, individualized approach is safe and effective in the management of new-onset symptoms of uncomplicated concussions.

Lumbar Diagnosis and Pressure Difference Variance.

CONTEXT: There is no consensus on the correlation between clinical experience and accuracy in diagnosing somatic dysfunctions, which makes it difficult to justify the use of more subjective measures to evaluate this important association. To better understand this relationship, palpatory forces can be observed while diagnosing a somatic dysfunction. OBJECTIVE: To quantify the pressure applied in diagnosing lumbar somatic dysfunction, find a correlation between accuracy of diagnosis and palpation pressure, set the standards for palpation, and develop precise palpatory skills for osteopathic medical students. METHODS: The palpatory forces were evaluated between participants with varying experience levels (osteopathic medical students and attending physicians from the New York Institute of Technology College of Osteopathic Medicine). Two osteopathic physicians confirmed an L5 somatic dysfunction diagnosis in a volunteer standardized patient (SP), who served as the control. Participants then palpated the lumbar segment of the SP in a prone position with F-Scan System (TekScan) sensors, which recorded the amount of pressure and time used to reach a full diagnosis. RESULTS: Participants (11 osteopathic medical students and 10 attending physicians) who diagnosed an L5 somatic dysfunction consistent with the SP's diagnosis had less of a difference in peak force (mean [SD] difference, 62.50 [325.7] g/cm2) between the contact points (right hand vs left hand). In contrast, participants with a dissimilar L5 diagnosis from the SP's had a mean (SD) difference in peak force of 319.38 (703.1) g/cm2. Similarly, the difference in the mean (SD) force of palpation between the contact points was lower in participants who made the correct diagnosis (16.81 [117.4] g/cm2) vs those who made an incorrect diagnosis (123.92 [210.3] g/cm2). No statistical significance was found between the diagnostic accuracy of the students and physicians (P=.387) or the time taken to reach a diagnosis (P=.199). CONCLUSION: We observed that using equal pressures in both hands while palpating a lumbar segment correlates to more accurate somatic dysfunction diagnoses.
