Relationship Between Hamstring Length and Gluteus Maximums in Mechanical Low Back Pain

Relationship Between Hamstring Length and Gluteus Maximums Strength With and Without Normalization in Mechanical Low Back Pain

The aim of this study was to determine the correlation between hamstring length and gluteus maximus strength with and without normalization in patients with mechanical low back pain

seventy-three patients diagnosed as mechanical low back pain. Firstly, gluteus maximus (GM) strength was measured isometrically as a force (kg) and then converted to torque (Nm). GM strength was normalized for body weight and height using the following formula: % (body weight × h) = torque (N × m) ×100 / body weight (N) × h (m), then assessment of hamstring length flexibility using the active knee extension method.

Data was collected and the correlation was determined.

Inclusion criteria:

• Patients diagnosed as mechanical low back pain (MLBP) with very high grade mechanical inflammatory low back pain (MIL) index.
• Age ranged from 18 to 40 years.
• Body mass index ranged from 25 to 30 kg/m2

Exclusion Criteria:

• History of previous fractures, surgeries, malignancies, trauma, rheumatoid arthritis, spondylosis, and spondylolisthesis.
• History of lower limb injuries in the last six months before the study.
• Inability to correctly produce maximal Gluteus Maximus contraction in a pain-free ROM.
