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

NCT03063814 | Completed

• 1 other identifier: ACL01
• Study Type: interventional
• Target: 47
• Locations: 1 country
• Sites: 1

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.

Conditions

Musculoskeletal Injury; Injury, Knee

Outcome Measures

Primary Outcomes (1)

• Normalized hamstring EMG

  Normalized to isometric MVC hamstring muscle EMG amplitude recorded during the exercise.

  5 minutes after instruction

Secondary Outcomes (2)

• Normalized quadriceps EMG

  5 minutes after instruction

• Joint angle

  5 minutes after instruction

APP

EXPERIMENTAL

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.

Behavioral: APP

PHY

ACTIVE COMPARATOR

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.
