Efficacy of a Supervised Intervention Protocol on Rounded Shoulder Posture and Shoulder ROM Among Saudi Young Females

Effectiveness of Strengthening and Stretching Exercise on the Resting Length of Pectoralis Minor Muscle and Shoulder Flexion of Young Females With Rounded Shoulder Posture

Shortening of pectoralis minor (PMi) muscle affects the scapular excursion that results in limited shoulder flexion range of motion (SFROM). The purpose is to evaluate the effect of Stretching of PM muscle along with the strengthening of lower trapezius (LTR) muscle to increase the length of PM muscle (PML) and limited SFROM in young adult females with rounded shoulder posture.

Study Overview

• Status: Completed
• Conditions: Postural; Defect
• Intervention / Treatment: Other: Active Stretching or Self-stretching exercises; Other: Active strengthening Or Self-Strengthening exercises

Detailed Description

Shortening of pectoralis minor (PMi) muscle affects the scapular excursion that results in limited shoulder flexion range of motion (SFROM). The purpose is to evaluate the effect of Stretching of PM muscle along with the strengthening of lower trapezius (LTR) muscle to increase the length of PM muscle (PML) and limited SFROM in young adult females with rounded shoulder posture.

Randomized sixty female subjects with rounded shoulder posture into two groups: Group A performed active Stretching of PMi along with the strengthening of LTR muscle(n=30); group B performed dynamic Stretching of PMi muscle only. Scores of outcome measures were recorded before and post interventions on day 0, day10th, and day21st, respectively.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Group A; Group A performed active Stretching of Pectoralis Minor (PMi) muscle along with the strengthening of Lower Trapezius muscle under the supervision of a physiotherapist	Other: Active Stretching or Self-stretching exercises; Pectoralis minor muscle was actively stretched under the supervision of a physiotherapist as follows: - 2 sets of 3-stretches/session/day, for 5 consecutive days a week, for 3 weeks; Other: Active strengthening Or Self-Strengthening exercises; Lower trapezius muscle was strengthened under the supervision of a physiotherapist as follows: -2 sets of 5-rep./session/day, for 5 consecutive days in 1st week, progressed to 10 and 20 reps./session/day for 2 weeks and 3 weeks respectively.
Active Comparator: Group B; Group B performed active Stretching of the Pectoralis Minor (PMi) muscle only under the supervision of a physiotherapist.	Other: Active Stretching or Self-stretching exercises; Pectoralis minor muscle was actively stretched under the supervision of a physiotherapist as follows: - 2 sets of 3-stretches/session/day, for 5 consecutive days a week, for 3 weeks
