Lower Cross SyndromeNCT06531746
Effect of Extracorporeal Shock Wave on Electrophysiological Changes and Pain in Patients With Lower Cross Syndrome
A study testing Extracorporeal shock wave and Conventional physical therapy program in people with Lower Cross Syndrome, run by Ahmed Alshimy at 1 site in Egypt.
Trial summary
Lower Cross Syndrome happens when there is muscular imbalance between weak and tight muscles. The tight muscles are generally the hip flexors and erector spinae, and weak muscles are the abdominals and gluteal muscles. Shortening occurs in the hip flexors while weakening occurs in the abdominals and gluteal muscles. Read more about this study

About this study
Lower Cross Syndrome happens when there is muscular imbalance between weak and tight muscles. The tight muscles are generally the hip flexors and erector spinae, and weak muscles are the abdominals and gluteal muscles. Shortening occurs in the hip flexors while weakening occurs in the abdominals and gluteal muscles.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Extracorporeal shock waveOther
Participants will receive (2.5 bars, 2000 pulses, 5 Hz, 7 min) rESWT with 1500 shock targeting the taut band of erector spinae, and 500 around the taut band, by using an EME S.r.l. via Degli Abeti 88/161122 Pesaro [serial number:
EM12681015], Italy, shock wave generator.
Conventional physical therapy programOther
Stretching and strengthening of Iliopoas muscle and Stretching and strengthening of Lower back muscles
Sham (No Treatment)Device
Sham extracorporeal shock wave will be introduced without real shock wave impulses.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Lower Cross Syndrome happens when there is muscular imbalance between weak and tight muscles. The tight muscles are generally the hip flexors and erector spinae, and weak muscles are the abdominals and gluteal muscles. Shortening occurs in the hip flexors while weakening occurs in the abdominals and gluteal muscles.

Group II (Control): will consist of 20 patients with lower cross syndrome and will receive sham extracorporeal shock wave in addition to conventional physical therapy program only same as group (I). For 12 sessions every other day, each session for 1 hour.

Questions about this trial
What is this clinical trial studying?
A study testing Extracorporeal shock wave and Conventional physical therapy program in people with Lower Cross Syndrome, run by Ahmed Alshimy at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Visual Analog Scale (time frame: 4 weeks). The study lists 2 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 19 May 2026.
