How completely are randomized controlled trials of non-pharmacological interventions following concussion reported? A systematic review. JOURNAL OF SPORT AND HEALTH SCIENCE 2024; 13:537-547. [PMID: 37619783 PMCID: PMC11184319 DOI: 10.1016/j.jshs.2023.08.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Revised: 05/20/2023] [Accepted: 07/12/2023] [Indexed: 08/26/2023]
Abstract
PURPOSE The study aimed to examine the reporting completeness of randomized controlled trials (RCTs) of non-pharmacological interventions following concussion. METHODS We searched MEDLINE, Embase, PsycInfo, CINAHL, and Web of Science up to May 2022. Two reviewers independently screened studies and assessed reporting completeness using the Template for Intervention Description and Replication (TIDieR), Consensus on Exercise Reporting Template (CERT), and international Consensus on Therapeutic Exercise aNd Training (i-CONTENT) checklists. Additional information was sought my study authors where reporting was incomplete. Risk of bias (ROB) was assessed with the Cochrane ROB-2 Tool. RCTs examining non-pharmacological interventions following concussion. RESULTS We included 89 RCTs (n = 53 high ROB) examining 11 different interventions for concussion: sub-symptom threshold aerobic exercise, cervicovestibular therapy, physical/cognitive rest, vision therapy, education, psychotherapy, hyperbaric oxygen therapy, transcranial magnetic stimulation, blue light therapy, osteopathic manipulation, and head/neck cooling. Median scores were: TIDieR 9/12 (75%; interquartile range (IQR) = 5; range: 5-12), CERT 17/19 (89%; IQR = 2; range: 10-19), and i-CONTENT 6/7 (86%; IQR = 1; range: 5-7). Percentage of studies completely reporting all items was TIDieR 35% (31/89), CERT 24% (5/21), and i-CONTENT 10% (2/21). Studies were more completely reported after publication of TIDieR (t87 = 2.08; p = 0.04) and CERT (t19 = 2.72; p = 0.01). Reporting completeness was not strongly associated with journal impact factor (TIDieR: rs = 0.27; p = 0.01; CERT: rs = -0.44; p = 0.06; i-CONTENT: rs = -0.17; p = 0.48) or ROB (TIDieR: rs = 0.11; p = 0.31; CERT: rs = 0.04; p = 0.86; i-CONTENT: rs = 0.12; p = 0.60). CONCLUSION RCTs of non-pharmacological interventions following concussion demonstrate moderate to good reporting completeness, but are often missing key components, particularly modifications, motivational strategies, and qualified supervisor. Reporting completeness improved after TIDieR and CERT publication, but publication in highly cited journals and low ROB do not guarantee reporting completeness.

Reduced Concussion Symptom Burden in Early Adolescent Athletes Using a Head-Neck Cooling Device. Clin J Sport Med 2024; 34:247-255. [PMID: 38180057 PMCID: PMC11042520 DOI: 10.1097/jsm.0000000000001198] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Accepted: 11/02/2023] [Indexed: 01/06/2024]
Abstract
OBJECTIVE To determine whether an investigational head-neck cooling device, Pro2cool, can better reduce symptom severity compared with standard postconcussion care in early adolescent athletes after a sports-related concussion. DESIGN Prospective, longitudinal, randomized trial design conducted over a 28-day period. SETTING Six pediatric medical centers in Ohio and Michigan. PARTICIPANTS The study enrolled 167 male and female 12- to 19-year-old athletes who experienced a sports-related concussion within 8 days of study enrollment and registering a Sports Concussion Assessment Tool 5 (SCAT5) composite score >7. INTERVENTIONS Pro2cool, an investigational head-neck cooling therapy device, was applied at 2 postinjury time points compared with postconcussion standard of care only. MAIN OUTCOME MEASURES Baseline SCAT5 composite symptom severity scores were determined for all subjects. Sports Concussion Assessment Tool 5 scores for concussed athletes receiving cooling treatment were analyzed across 6 independent postenrollment time points compared with subjects who did not receive cooling therapy and only standard care. Adverse reactions and participate demographics were also compared. RESULTS Athletes who received Pro2cool cooling therapy (n = 79) experienced a 14.4% greater reduction in SCAT5 symptom severity scores at the initial visit posttreatment, a 25.5% greater reduction at the 72-hour visit posttreatment, and a 3.4% greater reduction at the 10-day visit compared with subjects receiving only standard care (n = 88). Overall, 36 adverse events (increased blood pressure, decreased pulse, and dizziness) were reported, with 13 events associated with the device, of which 3 were classified as moderate in severity. CONCLUSIONS This study demonstrates the efficacy and safety of head and neck cooling for the management of concussion symptoms in adolescent athletes of an age group for which little to no prior data are available.

Abstract
BACKGROUND Numerous individual studies suggest that rest may have a negative effect on outcomes following concussion. PURPOSE To perform a systematic meta-analysis of the effects of prescribed rest compared with active interventions after concussion. STUDY DESIGN Meta-analysis; Level of evidence, 4. METHODS A meta-analysis (using the Hedges g) of randomized controlled trials and cohort studies was conducted to evaluate the effects of prescribed rest on symptoms and recovery time after concussion. Subgroup analyses were performed for methodological, study, and sample characteristics. Data sources were obtained from systematic search of key terms using Ovid Medline, Embase, Cochrane Database of Systematic Reviews, APA PsycINFO, Web of Science, SPORTDiscus, and ProQuest dissertations and theses through May 28, 2021. Eligible studies were those that (1) assessed concussion or mild traumatic brain injury; (2) included symptoms or days to recovery for ≥2 time points; (3) included 2 groups with 1 group assigned to rest; and (4) were written in the English language. RESULTS In total, 19 studies involving 4239 participants met criteria. Prescribed rest had a significant negative effect on symptoms (k = 15; g = -0.27; SE = 0.11; 95% CI, -0.48 to -0.05; P = .04) but not on recovery time (k = 8; g = -0.16; SE = 0.21; 95% CI, -0.57 to 0.26; P = .03). Subgroup analyses suggested that studies with shorter duration (<28 days) (g = -0.46; k = 5), studies involving youth (g = -0.33; k = 12), and studies focused on sport-related concussion (g = -0.38; k = 8) reported higher effect sizes. CONCLUSION The findings support a small negative effect for prescribed rest on symptoms after concussion. Younger age and sport-related mechanisms of injury were associated with a greater negative effect size. However, the lack of support for an effect for recovery time and the relatively small overall numbers of eligible studies highlight ongoing concerns regarding the quantity and rigor of clinical trials in concussion.

Abstract
OBJECTIVES We evaluated interventions to facilitate recovery in children, adolescents and adults with a sport-related concussion (SRC). DESIGN Systematic review including risk of bias (modified Scottish Intercollegiate Guidelines Network tool). DATA SOURCES MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Embase, APA PsycINFO, Cochrane Central Register of Controlled Trials, CINAHL Plus with Full Text, SPORTDiscus and Scopus searched until March 2022. STUDY ELIGIBILITY CRITERIA (1) Original research including randomised controlled trials (RCTs), quasi-experimental designs, cohort, comparative effectiveness studies; (2) focus on SRC; (3) English; (4) peer-reviewed and (5) evaluated treatment. RESULTS 6533 studies were screened, 154 full texts reviewed and 13 met inclusion (10 RCTs, 1 quasi-experimental and 2 cohort studies; 1 high-quality study, 7 acceptable and 5 at high risk of bias). Interventions, comparisons, timing and outcomes varied, precluding meta-analysis. For adolescents and adults with dizziness, neck pain and/or headaches >10 days following concussion, individualised cervicovestibular rehabilitation may decrease time to return to sport compared with rest followed by gradual exertion (HR 3.91 (95% CI 1.34 to 11.34)) and when compared with a subtherapeutic intervention (HR 2.91 (95% CI 1.01 to 8.43)). For adolescents with vestibular symptoms/impairments, vestibular rehabilitation may decrease time to medical clearance (vestibular rehab group 50.2 days (95% CI 39.9 to 60.4) compared with control 58.4 (95% CI 41.7 to 75.3) days). For adolescents with persisting symptoms >30 days, active rehabilitation and collaborative care may decrease symptoms. CONCLUSIONS Cervicovestibular rehabilitation is recommended for adolescents and adults with dizziness, neck pain and/or headaches for >10 days. Vestibular rehabilitation (for adolescents with dizziness/vestibular impairments >5 days) and active rehabilitation and/or collaborative care (for adolescents with persisting symptoms >30 days) may be of benefit.

Abstract
A sports-related concussion (SRC) is most commonly sustained in contact sports, and is defined as a mild traumatic brain injury. An exercise-induced elevation of core body temperature is associated with increased brain temperature that may accelerate secondary injury processes following SRC, and exacerbate the brain injury. In a recent pilot study, acute head-neck cooling of 29 concussed ice hockey players resulted in shorter time to return-to-play. Here, we extended the clinical trial to include players of 19 male elite Swedish ice hockey teams over 5 seasons (2016-2021). In the intervention teams, acute head-neck cooling was implemented using a head cap for ≥45 minutes in addition to the standard SRC management used in controls. The primary endpoint was time from SRC until return-to-play (RTP). Sixty-one SRCs were included in the intervention group and 71 SRCs in the control group. The number of previous SRCs was 2 (median and interquartile range (IQR): 1.0 - 2.0) and 1 (IQR 1.0 - 2.0) in the intervention and control groups, respectively; p= 0.293. Median time to initiate head-neck cooling was 10 min (IQR 7-15; range 5-30 min) and median duration of cooling was 45 min (IQR 45-50; range 45-70 min). The median time to RTP was 9 days in the intervention group (IQR 7-13.5 days) and 13 days in the control group (IQR 9-30; p<0.001). The proportion of players out from play for more than the expected recovery time of 14 days was 24.7% in the intervention group, and 43.7% in controls (p<0.05). Study limitations include that a) allocation to cooling or control management was at the discretion of the medical staff of each teams, decided prior to each season, and not by strict randomization, b) no sham cap was used and evaluations could not be performed by blinded assessors and c) it could not be established with certainty that injury severity was similar between groups. While the results should thus be interpreted with caution, early head-neck cooling, with the aim of attenuating cerebral hyperthermia, may reduce post-SRC symptoms and lead to earlier return-to-play in elite ice hockey players.
