Effects of App-based Versus Personal On-site Instruction on Neuromuscular Activity in Injury Prevention Exercises

Not Applicable

Completed

• Conditions: Musculoskeletal Injury; Injury, Knee
• Interventions: Behavioral: PHY; Behavioral: APP

• Registration Number: NCT03063814
• Lead Sponsor: National Research Centre for the Working Environment, Denmark

Brief Summary

Therefore, the aim of the present study was to evaluate neuromuscular characteristics observed during a single bout of selected and validated injury preventive exercises instructed by an app (in accordance with 'Get set - Train smarter') versus gold standard instruction, supervision and feedback provided on-site by an expert. The present evaluation targets a population of female football and handball players without any previous exposure to injury prevention training.

Arm && Interventions

Group	Intervention	Description
PHY	PHY	In PHY, a physiotherapist demonstrated and explained the focus areas of each of the five exercises before the participant performed the exercises. If needed, verbal feedback was given between trials to correct the performance of the exercise. The physiotherapist approved trials that were performed with proper technique.
APP	APP	In the APP group, a video sequence of each exercise, supported by short written descriptions (in accordance to 'Get set - Train smarter', (9) on how to perform the exercise correctly, was shown to the participants on an iPad. The video-recorded exercises were performed by the same physiotherapist who supervised PHY participants. If required, the participants in the APP group were allowed to watch the video and description several times between trials of the same exercise. The participants approved their own trials when they believed that the exercises had been performed as described.

Primary Outcome Measures

Name	Time	Method
Normalized hamstring EMG	5 minutes after instruction	Normalized to isometric MVC hamstring muscle EMG amplitude recorded during the exercise.

Secondary Outcome Measures

Name	Time	Method
Normalized quadriceps EMG	5 minutes after instruction	Normalized EMG amplitude of the quadriceps muscle recorded during the exercise.
Joint angle	5 minutes after instruction	Joint angle during the exercise
