COMPREHENSIVE JOINT FLEXIBILITY ASSESSMENT IN LOWER EXTREMITIES AND SPINAL COLUMN:

Background: Spinal column and lower extremity flexibility are critical components of functionalmovement, athletic performance, and injury prevention. Digital goniometry offers objective, preciseassessment capabilities superior to traditional measurement methods.Objective: To comprehensively evaluate static flexibility of the cervical spine, thoracolumbar spine,coxofemoral joint, knee, and ankle using the Mobee Med digital goniometry system, establishingnormative data and identifying clinical flexibility patterns.Methods: Three healthy adult subjects underwent systematic flexibility assessment using Mobee Med (TGA-registered) with 142 standardized mobility tests. Evaluations included: cervical spine(flexion/extension, lateral bending, rotation), thoracolumbar spine (flexion/extension, lateral bending, rotation), coxofemoral joint (flexion/extension, abduction/adduction, rotations), knee(flexion/extension), and ankle (dorsiflexion/plantarflexion, eversion/inversion). Statistical analysisutilized descriptive statistics and one-sample t-tests comparing measured values against referencestandards (α=0.05).Results: Significant deficits were identified across multiple regions. Cervical spine: flexion 70.67°±3.06(reference 80°, p=0.034), left rotation 77.67°±3.51 (reference 85°, p=0.026). Thoracolumbar spine:extension 15.00°±3.61 (reference 25°, p=0.041). Coxofemoral joint: left hip flexion 118.33°±2.52(reference 125°, p=0.004), right abduction 55.33°±3.51 (reference 70°, p=0.010). Knee: left flexion120.33°±5.51 (reference 135°, p=0.044). Ankle: dorsiflexion 15.00°±2.00 left, 14.33°±2.52 right(reference 20°); plantarflexion 42.67°±7.77 left, 43.33°±4.04 right (reference 55°). Statistical analysisrevealed flexibility restrictions averaging 10-40% below reference values, with larger deficits inextension movements and rotational patterns.Conclusions: Digital goniometry reveals systematic flexibility deficits in spinal and lower extremityjoints even in healthy populations. Cervical and thoracolumbar extension limitations (26.67-66.67%deficits) reflect modern postural dysfunction from prolonged sitting and forward head positioning.Coxofemoral restrictions in flexion (5.63%), abduction (26.51%), and rotations (20-27%) indicate hip musculature tightness predisposing to low back pain and lower extremity pathology. Knee flexiondeficits (10.89-12.19%) and ankle mobility restrictions (25-28.90%) compromise functional movementpatterns essential for daily activities and athletic performance. The Mobee Med system provides precise, standardized assessment enabling early intervention before clinical symptom manifestation.
