ABSTRACT
BACKGROUND AND OBJECTIVES:
The treatment for greater trochanteric pain syndrome (GTPS) is conservative. However, there are few studies that prove these results. The objective of this study was to analyze the effect of increasing hip and trunk muscle strength on pain, functional capacity, core muscle endurance, and postural control of women with GTPS.
METHODS:
This study is a clinical trial. Twenty-six women with GTPS were assigned into Group 1 (G1, n=12, hip strength exercises) and Group 2 (G2, n=14, hip and core strength exercises) and were evaluated before the start, after the intervention protocol, and after the follow-up of 12 weeks (Follow-Up - FU). Pain, functional capacity, core endurance and postural control were evaluated. The Prone Bridge test (PBT) and Supine Bridge test (SBT) established core endurance.
RESULTS:
The pain decreased after the interventions and FU (p=0.001), with a strong effect (1.62≤d≤2.35), with no differences between groups (p=0.29). Functional capacity improved after the interventions and FU (p=0.03), with a poor effect (0.19≤d≤0.27), with no differences between groups (p=0.61). The time in the PBT increased for both groups (p=0.62), with a strong effect in G2 (d=1.02). The SBT established that G2 was better after the intervention and FU (p=0.04; d=0.20), with no differences between the moments (p=0.95). Postural control showed no differences.
CONCLUSION:
Strength exercises for the hips only or for the hips and core decreased pain and improved functional capacity and core endurance in GTPS.

HIGHLIGHTS
Hip and core muscle strengthening exercises improve pain and functional capacity of women with Greater Trochanter Pain Syndrome (GTPS).
Hip and core muscle strengthening exercises did not change the postural control of women with GTPS.
Hip muscle strengthening exercises and hip + core muscle strengthening exercises have similar effects.
