Abstract

Background and Objective:Altered Pattern of the Global Muscle system is presented in literature among individuals with sacroiliac Joint Dysfunctions. However, the pattern of changes in the Latissimus dorsi (LD) and gluteal maximus (GM) among sacroiliac joint dysfunctions (SIJD) is not reported. This study aimed to investigate the changes in the resting muscle thickness of the Latissimusdorsi and gluteal maximus in SIJD.Method:A total of 88 subjects (44 individuals with SIJD and 44 healthy individuals as matched control) was included in this study. The resting thickness of the Latissimusdorsi and gluteal maximus was measured using real time musculoskeletal ultrasonography and data was compared between the ipsilateral side and contra lateral side among subjects with SIJD as well as healthy subjects. Independent sample t test was used to analyze the data by using SPSS version-25.Results:The results showed that contralateral LD were reduced significantly among subjects with SIJD when compared with the other side and with control. It also showed that ipsilateral IO, TrA and GM were reduced significantly among subjects with SIJD when compared with the controls and with contralateral side.Conclusion:The reduced resting muscle thickness showed an altered motor pattern of Deep Muscles of local system and Gross muscles of global system among patients with sacroiliac joint dysfunction.

Highlights

Sacroiliac joint is a diarthrodial synovial joint and a source of low back pain and referred pain in the lower extremity.[1]
Compressive forces across the pubic symphysis are increased by activation of the obliqus internal (IO) and adductor longus, whereas activation of the IO, transverses abdominus (TrA), gluteus maximus, latissimus dorsi, and lumbar erector spinae increase compressive forces across the SIJ.[3]
The healthy subjects were matched as controls in terms of age, weight, height and body mass index (BMI).Any patients who reported disc pathology, history of spinal surgeries, any musculoskeletal symptoms on the lower limb over the past year and participants undergone any type of regular exercise over last three months were excluded

This study aimed to investigate the changes in the resting muscle thickness of the Latissimusdorsi and gluteal maximus in SIJD.

Conclusion: The reduced resting muscle thickness showed an altered motor pattern of Deep Muscles of local system and Gross muscles of global system among patients with sacroiliac joint dysfunction
