The Effects of Schroth Based Exercise Therapy in Adolescents with Pectus Excavatum

January 6, 2025 updated by: Busra Kandemir, Hacettepe University
Research on exercise methods for pectus excavatum (PE) is limited, highlighting the need for further studies. This study investigated the effects of Schroth-based exercise therapy combined with vacuum treatment in 35 adolescents with PE, divided into a vacuum + exercise group (n=19) and a vacuum-only group (n=16). Outcomes included deformity severity, sagittal posture, thoracic cage and spinal mobility, muscle endurance, and quality of life. The combination therapy significantly improved sagittal spinal posture (craniovertebral, thoracic, thoracolumbar, lumbar angles) and deformity-specific quality of life (Nuss Questionnaire scores) compared to vacuum-only treatment.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • having pectus excavatum
  • being 10-18 years
  • having Haller index more than 2.5

Exclusion Criteria:

  • Individuals with pectus excavatum associated with a syndrome Individuals with mixed deformity
  • Individuals who have previously received any conservative treatment or surgery for chest deformity or spinal issues
  • Individuals with neuromuscular, rheumatic, or chronic systemic diseases

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Non-Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: vacuum only
Experimental: Vacuum plus exercise
Other: Exercise
Due to the limited research on exercise approaches for pectus excavatum, further investigation in this field is needed. This study aims to explore the impact of Schroth-based exercise therapy on adolescents with pectus excavatum.
