The Refinement of a Previously Tested Concussion Protocol to Improve Its Clinical Utility
Notice bibliographique
Résumé
College of Kinesiology Research Theme: Human Performance Background: Concussions are a complex pathophysiological process that can affect balance control, emphasizing the importance of measuring balance during concussion rehabilitation. Previous research evaluated the feasibility of a balance assessment protocol comprised of 24 standing tasks (e.g., one/two legs, eyes open/closed, on/off foam, with/without a figure 8 head movement, with/without a reaction time task). Fifteen of the 24 tasks were deemed feasible; however, the reliability, clinical implementation, and clinical utility of those tasks are unknown. This research examined the reliability of those 15 tasks, gathered clinician insights, and evaluated the clinical utility to develop a refined balance assessment protocol for people undergoing concussion rehabilitation. We hypothesized that the clinical utility index (CUI) would increase after our refinements. Methods: Participants completed the standing balance tasks while standing on force plates (VALD Force Decks) to measure Centre of Pressure (COP) movement. Reliability of the COP data for participants without a history of concussion who completed the tasks twice 2-20 days apart was examined using Intraclass correlation coefficients (ICCs) for normally distributed data and Lin’s Concordance Coefficient (Rc) for non-normally distributed data (α =.05). Tasks with ≥ moderate reliability were compared between participants with and without a history of concussion using independent t-tests (α =.05). We shared results with four practicing clinicians (physiotherapists at a local clinic) to gather their clinical input and determine which tasks would be clinically useful. Clinical utility was calculated for the original and refined protocols. Results: Six of the 15 feasible tasks had significant (p<.05), moderate-good reliability, including quiet standing eyes closed, quiet standing single leg, quiet standing single leg eyes closed, figure 8 single leg, figure 8 on foam single leg, and a lower extremity reaction time test. The quiet standing eyes closed and quiet standing single leg tasks differentiated between groups with and without a history of concussion. Clinicians chose the quiet standing eyes closed, figure 8 single leg, and lower extremity reaction time tasks as tasks they could incorporate into their current concussion rehabilitation protocol. The CUI changed from 1 (original protocol) to 5 (refined protocol). Discussion: Using the previously established feasibility results and calculated reliability results changed the number of tasks from 15 to 3, which increased the CUI and represents a more clinically useful protocol. The feasibility and reliability results allowed clinicians insight into which tests are best to implement into their current protocol. The quiet standing eyes closed task serves as a simple baseline test, while the figure 8 single leg task incorporates vestibular activation, and the lower extremity reaction time task adds a cognitive challenge to balance. Future research could implement these three tasks in people undergoing concussion rehabilitation to determine if they are beneficial in detecting changes in balance and for clinical decision-making.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
