The purpose of this study was to investigate the validity of automatically stored exercise-data from the elastic band sensor© compared to a gold-standard stretchsensor during exercises commonly used for rehabilitation of the hip and knee. The design was a concurrent validity study. Participants performed three sets of 10 repetitions of six exercises with both sensors attached to the same elastic exercise band. These were knee extension, knee flexion, hip abduction and adduction, hip flexion and hip external rotation. Agreement between methods was calculated for: date, time-of-day, repetitions, total and single repetition, and contraction-phase specific time-under-tension (TUT). Files from the elastic band sensor© contained identical dates, time-of-day and number of repetitions for each exercise set compared to the gold-standard. Total TUT and total single repetition TUT were highly correlated with the stretch-sensor (r=0.83-0.96) but lower for contraction-phase specific TUTs (r=0.45-0.94). There were systematic differences between the methods ranging from 0.0-2.2 seconds (0.0-6.3%) for total TUT and total single repetition TUT, and between 0.0-3.3 seconds (0.0-33.3%) for contraction-phase specific TUTs. The elastic band sensor© is a valid measure of: date, time-of-day, number of repetitions and sets, total TUT, and total single repetition TUT during commonly used home-based strength training exercises. However, the elastic band sensor© seems unable to validly measure TUT for specific contraction-phases.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
