Assessing the effects of concussion using the C3Logix Test Battery: An exploratory study

Abstract

The C3Logix is a computerized concussion assessment tool that measures a wider array of symptoms (i.e., balance and oculomotor functioning) than other computerized batteries. Although the C3Logix has been used increasingly by athletic organizations at all levels of play, its utility within the concussion population has not been extensively examined. The current study aimed to determine whether the C3Logix is sensitive to the effects of concussion. A total of 54 student-athletes enrolled at a large southern university completed the C3Logix at baseline and within days following a suspected concussion (mean = 2.93, SD = 3.14). Dependent-samples t-tests revealed that relative to their baselines, following concussion, athletes both reported significantly greater postconcussive symptoms and performed more poorly on measures of reaction time and computer-measured balance. Decrements in processing speed, visual acuity, and clinician-observed errors on tests of balance also trended toward significance. Results suggest that inclusion of measures of balance and oculomotor functioning in the assessment of concussion may provide additional clinical utility above and beyond domains typically measured by computerized concussion assessments.

The relation between neck strength and psychological distress: preliminary evidence from collegiate soccer athletes

“…Age and sport participation were collected by research personnel. Neck pain at the time of testing was determined using one question from the C3Logix graded symptom checklist (NeuroLogix Technologies, OH, USA); ‘neck pain’ was rated on a 7-point Likert scale with 0 = normal and 6 = severe [ 36 ]. Height and weight were collected by athletic personnel using a physician beam scale with height rod (Health o meter ® Professional Scales, model 402KL; Pelstar LLC, IL, USA) and used to determine BMI.…”

Insular Connectivity Is Associated With Self-Appraisal of Cognitive Function After a Concussion

“…For all participants, computerized neurocognitive testing was administered at the time of imaging using the C3 Logix platform, which is designed for longitudinal assessment of domains typically affected by concussive blows (e.g., reaction time, processing speed, memory, and visuospatial function), with good test-retest reliability and validity (36,37). Subtests were presented in a fixed order for all participants within a single session, but with randomization between sessions.…”

Reliability, Validity and Utility of Inertial Sensor Systems for Postural Control Assessment in Sport Science and Medicine Applications: A Systematic Review

“…Eight observational case-control studies focused on comparing concussed and healthy control groups [14,15,[51][52][53][54][55][56], with 5/8 studies demonstrating statistically significant differences between concussion and healthy cohorts. A single prospective cohort study compared athletes healthy baseline and concussed measurements, reporting statistically significant differences between testing points in the DLS EC condition [57]. Two observational case-control studies focused on CAI, reporting conflicting findings when differentiating healthy and CAI [58,59].…”

“…Eight observational case-control studies [14,15,[51][52][53][54][55][56] and a single prospective cohort study [57] investigated the effect of concussion on the instrumented PC assessment scores. Four out of five BESS/mBESS case-control studies [15,[53][54][55] and a single CTSIB protocol [56] demonstrated that sensor derived measures were able to differentiate concussed and non-concussed subjects with a greater degree of accuracy than the traditional measures.…”

Additionally, Bernstein and colleagues [57] prospective investigation reported that the sensor-based measure detected deteriorations in DLS EC balance performance in athletes, post-concussion. In contrast, two studies reported that the instrumented BAM [14] and DLS EO (with/without cognitive task) [51] did not differentiate concussed and healthy control groups.…”
