A study testing Strengthening exercises in people with Strength, run by University of Liege at 1 site in Belgium.
Trial summary
The objective of the study was to compare analytic, functional and mixed (analytic/functional) methods in strengthening rotator cuff and scapular stabilizers muscles. For that purpose, participants had to follow a strengthening program 3 times a week during 8 weeks. Read more about this study

About this study
Official title: Functional or Analytic Methods: What is the Best to Strengthen Shoulder and Scapular Muscles?
The objective of the study was to compare analytic, functional and mixed (analytic/functional) methods in strengthening rotator cuff and scapular stabilizers muscles. For that purpose, participants had to follow a strengthening program 3 times a week during 8 weeks.
Read the detailed description
Each participant was allocated to a group (analytic, functional and mixed groups) in a random way while assuring that the groups were quite similar in morphological data or in performance. The strengthening program has to be performed three times a week during eight weeks by each participant.
The exercises included in the program were chosen among the bests exercises described in literature to active shoulder rotators as well as scapular stabilizing muscles. The analytic group has to perform the following exercises: prone rowing with dumbbell, prone external rotation at 90° of abduction, prone extension, bilateral scapular protraction with dumbbells, eccentric internal rotation at 90° of abduction, external rotation diagonal exercise and single arm shot put medicine ball throw. The functional group performed the same exercises but with a functional component: standard plank rowing, swissball external rotation at 90° of abduction, standard plank extension, bilateral scapular protraction (standard plank + raised feet), eccentric internal rotation 90° of abduction with unipodal glute bridge, external rotation diagonal in an unipodal position and single arm shot put throw with medicine ball in and single arm shot put medicine ball throw. Then, for the mixed group, the program included exercises from the analytic group and other ones from the functional group in equal parts. For all the groups, the exercises aimed to strengthen shoulder rotators were performed five times in a row and the others aimed to strengthen scapular stabilizing muscles were performed fifteen times in a row. The only exception was for the single arm shot put medicine ball throw that was performed ten times. Two series of each exercises were performed during each session, which represent a mean duration of thirty minutes.
At the beginning and at the end of the intervention, three different evaluations were performed :
- Measurement of shoulder rotators strength (with an isokinetic device)
- Measurement of scapular stabilizers strength (with an isokinetic device)
- Measurement of functional performance (with Medicine Ball Throw, CKCUEST, Y Balance Test and a core stability test)

What does the primary outcome measure?
Shoulder rotators strength (time frame: Change from baseline at 8 weeks). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 May 2022; AzTrials last refreshed its copy on 30 Oct 2026.
