Background: A significant part of successful athletic performance is the use of peripheral vision. A divide visual attention task with a central and peripheral target was used to assess athletes with and without a history of concussion. The research suggests that both groups had the same response accuracy in the task performance. The purpose of this research was to determine if peripheral visual attention is impacted in ice hockey players who have had a history of one or more self reported concussion. Methods: Orientation discrimination accuracy of a pair of Landolt type block “C” targets was measured using a divided covert attention task on 22 collegiate level men’s ice hockey players. Stimuli were presented simultaneously at central fixation and at one of 40 peripheral locations against a bright white background for two stimulus durations (150ms and 15ms). Block “C” targets were presented at one of 4 orientations (up, down, left and right) and randomized for central and peripheral locations. Results: Overall there was a statistically significant difference in the performance at 150ms and 15ms stimuli durations; athletes had a larger area of correct responses with the 150ms stimulus duration. Athletes performed better in the horizontal meridian compared to the vertical meridian for both stimulus durations. Conclusion: The divided visual attention test results for a cohort of university level men’s ice hockey players shows a decline in area of correct responses with shorter stimulus durations. There was no difference in response accuracy between those with a history of a concussion compared to those without a previous concussion.

Object The aim of this study was to examine the brain's white matter microstructure by using MR diffusion tensor imaging (DTI) in ice hockey players with a history of clinically symptomatic concussion compared with players without a history of concussion. Methods Sixteen players with a history of concussion (concussed group; mean age 21.7 ± 1.5 years; 6 female) and 18 players without a history of concussion (nonconcussed group; mean age 21.3 ± 1.8 years, 10 female) underwent 3-T DTI at the end of the 2011–2012 Canadian Interuniversity Sports ice hockey season. Tract-based spatial statistics (TBSS) was used to test for group differences in fractional anisotropy (FA), axial diffusivity (AD), radial diffusivity (RD), and the measure “trace,” or mean diffusivity. Cognitive evaluation was performed using the Immediate Postconcussion Assessment and Cognitive Test (ImPACT) and the Sport Concussion Assessment Tool–2 (SCAT2). Results TBSS revealed a significant increase in FA and AD, and a significant decrease in RD and trace in several brain regions in the concussed group, compared with the nonconcussed group (p < 0.05). The regions with increased FA and decreased RD and trace included the right posterior limb of the internal capsule, the right corona radiata, and the right temporal lobe. Increased AD was observed in a small area in the left corona radiata. The DTI measures correlated with neither the ImPACT nor the SCAT2 scores. Conclusions The results of the current study indicate that a history of concussion may result in alterations of the brain's white matter microstructure in ice hockey players. Increased FA based on decreased RD may reflect neuroinflammatory or neuroplastic processes of the brain responding to brain trauma. Future studies are needed that include a longitudinal analysis of the brain's structure and function following a concussion to elucidate further the complex time course of DTI changes and their clinical meaning.

  Introduction Significant part of sports related concussions (SRC) are below the level of clinical diagnosis of SRC or are unnoticed. The most severe cumulative consequence of SRC is chronic traumatic encephalopathy (CTE). The study of a wide range of clinical manifestations of CTE plays an important role. Purpose To establish long-term cognitive consequences of TBI in ice hockey players. Material and methods Retrospectively, we tested retired 20 ice hockey players. All athletes completed a questionnaire with their team doctor, which included: passport part, sports history, history of SRC, a mini mental scale evaluation (MMSE) and «the clock drawing test». Results The results of the analysis showed a statistically significant decrease in the value of MMSE with an increase in SRC more than 1 during a sports career. Thus, in the group with 1 SRC the value of MMSE was 28.7 (1.38) points, while in the group with 2 or more SMS it was equal to 26.7 (1.15) points (p <0.05). MMSE goalkeepers scored 26.6 (0.6) points, strikers – 27.8 (0.4) points, defenders – 28.2 (0.7) points (p<0.05). The fact of hospitalization indicates clinically significant severity of a history of SRC. Having retrospectively collected data on hospitalization of hockey players after SRC, there was also a decrease in the value of MMSE in those with a history of hospitalization. Thus, in the group of people with hospitalization MMSE was 27.1 (1.39) points, without hospitalization – 27.9 (1.7). No statistically relationship between age and severity of cognitive impairment was found. Significant statistic connection (n = 20, correlation coefficient rs = – 0.40; p<0.05) has been found between the number of SRC and the indicator and MMSE test and between number of SRC and «the clock drawing test» (n = 20, correlation coefficient rs = – 0.10; p <0.05). Conclusions Our study has outlined connection between cognitive impairment in ice-hockey players and SRC.

ABSTRACT Context: The epidemiological focus on time loss may underestimate the true magnitude of hip and groin problems in male ice hockey players. Objective: To describe the prevalence, incidence and severity of hip and groin problems (time loss and non-time-loss) in Swedish ice hockey players over the course of a season and to explore potential pre-season risk factors for these problems. Design: Prospective one-season cohort study Setting: Professional and semi-professional Swedish ice hockey Patients or other participants: Twelve professional and semi-professional male ice hockey teams were invited to participate. Nine teams agreed to participate, and 163 players were included in analyses. Main outcome measures: Hip and groin problems in the previous season (time loss; non-time-loss), isometric adduction and abduction strength, and five-second squeeze test were recorded prior to the season and served as independent variables in the risk factor analysis. Main outcome measures were cumulative incidence of hip and groin problems, average prevalence, and odds ratios for groin problems in-season Results: Cumulative incidence for all problems was 45.4 % (95% CI 37.6–53.4) and 19% (13.3–25.9) for substantial problems. Average prevalence was 14.1% (10.8–17.5) for all and 5.7% (4.3–7.2) for substantial problems. Among reported problems, 69.2% had gradual onset; where only 17% lead to time loss. Players with non-time-loss problems in the previous season had significantly higher odds for new problems [All: OR 3.3 (1.7–6.3); Substantial: OR 3.6 (1.8–8.4)]. Pre-season strength was not significantly associated with the odds for subsequent problems. Conclusion: Hip and groin problems are common in ice hockey and may lead to substantial impairments in performance. Only one in five problems led to time loss and 7 out of 10 had gradual onset. Non-time-loss problems in the previous season were found to be a significant risk factor for new problems whereas preseason hip adduction and abduction strength was not.

Background: Hip and groin problems are just as common in ice hockey as they are in soccer. The 5-second squeeze test (5SST) is a valid indicator of hip- and groin-related sporting function (self-reported function) in soccer and is suggested to be interpreted according to a “traffic light” approach in guiding the early identification and management of affected players. It is currently unknown how the 5SST relates to self-reported function and muscle strength in ice hockey players. Purpose: To investigate correlations between the 5SST result, self-reported function, and hip muscle strength in ice hockey players. A further aim was to investigate the discriminative ability of the “traffic light” approach (numeric rating scale [NRS] score: 0-2 = green, 3-5 = yellow, 6-10 = red) regarding levels of self-reported function and strength. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Professional and semiprofessional male ice hockey players (N = 333) performed the 5SST and completed the Sport subscale of the Copenhagen Hip and Groin Outcome Score (HAGOS). Bilateral adduction and abduction strength was measured using handheld dynamometry. Associations were estimated using Spearman rank-order correlations, and groups were compared using the Kruskal-Wallis test or analysis of variance. Standardized effect sizes (ESs) for differences in strength (Hedges g) and self-reported function ( r) were provided. Results: The 5SST result was significantly correlated with self-reported function (rho, –0.319; P < .01) and hip muscle strength (rho, –0.157 to –0.305; P < .01). The HAGOS Sport scores differed significantly between all 3 traffic light groups (ES, 0.23-0.33; P ≤ .005). Players with an NRS score >2 (yellow or red light) had lower adduction (ES ≥ 0.75; P < .001) and abduction strength (yellow: ES, 0.30; P = .031) (red: ES, 0.51; P = .058) than players with a green light. Conclusion: The 5SST result was significantly correlated with self-reported function as well as hip muscle strength and was able to discriminate between the traffic light levels in ice hockey players. Players with a yellow or red light had reduced adduction and abduction strength compared with players with a green light (NRS score ≤2). Routine 5SSTs may allow the early identification of affected ice hockey players and indicate yellow and red light situations, in which players may benefit from load management and appropriate hip muscle strengthening.
