Comparison of scapular posterior tilting exercise alone and scapular posterior tilting exercise after pectoralis minor stretching on scapular alignment and scapular upward rotators activity in subjects with short pectoralis minor.

Objectives: To compare scapular posterior tilting exercise alone and scapular posterior tilting exercise after pectoralis minor (PM) stretching on the PM index (PMI), scapular anterior tilting index, scapular upward rotation angle, and scapular upward rotators' activity in subjects with a short PM.

Participants: Fifteen subjects with a short PM participated in this study.

Main Outcome Measures: The PMI, scapular anterior tilting index, and scapular upward rotation angle were measured after scapular posterior tilting exercise alone and scapular posterior tilting exercise after PM stretches.

Trunk muscle activation during different quadruped stabilization exercises in individuals with chronic low back pain.

Background And Purpose: The aim of this study was to compare the trunk muscle activities and the local/global activity ratios of the abdominal, back and trunk muscles during stabilization exercises such as one arm raise (AR), one leg raise (LR), and opposing arm/leg raise (ALR) in patients with chronic low back pain (LBP).

Method: Ten individuals with chronic LBP (five men and five women) participated in this study. The external oblique abdominis, internal oblique abdominis, multifidus, thoracic part of the lumbar iliocostalis and the local/global activity ratio were assessed, while quadruped stabilization exercises were performed (AR, LR, and ALR); each exercise was carried out three times.

The effect of scapular posterior tilt exercise, pectoralis minor stretching, and shoulder brace on scapular alignment and muscles activity in subjects with round-shoulder posture.

Background: There are various methods for rehabilitating round-shoulder posture (RSP), including strengthening exercises, stretching, and using a shoulder brace or taping to correct the altered posture. However, no study has determined which intervention is the most effective of the three methods to decrease RSP (intervention #1: scapular posterior tilting exercise alone [hereafter, SPT], intervention #2: the scapular posterior tilting exercise after PM stretching [PM stretch+SPT], and intervention #3: the scapular posterior tilting exercise with use of a shoulder brace [SPT+brace]).

Objectives: The purpose of this study was to compare the SPT, PM stretch+SPT, and SPT+brace on RSP, PM index (PMI), and lower trapezius (LT) and serratus anterior (SA) activity in subjects with RSP.
