Tragus-wall distance (TWD), modified Schober's test (MST), and chest expansion were measured for postural assessment.
They reported that there was no difference between healthy controls and AS patients in terms of balance and general stability parameters and they found a negative correlation between Schober's test and general stability scores.
The flexibility levels of the study participants were measured before and after the Clinical Pilates education using finger-to-floor test and modified Schober's test.
The results of both modified Schober's test and finger-to-floor test, which were used to measure the flexibility levels, showed a statistically significant increase in post-education scores compared with those of the pre-education period.
Zaniewska and colleagues  described the improvement of a range of mobility in a lumbar spine in a group of 30 patients evaluated via Schober's test
For this test I have used the Schober's Test
which measures the lumbar spine's flexion.
(8) to assess the Lumbar spina l mobility, Occiput-wall distance to assess the cervical spinal mobility and Finger-floor distance to assess the Thoraco- Lumbar spinal mobility was done in each of the patients.
Demographic characteristics, disease duration, treatments, physical examination findings (neck circumference, occiput-to-wall distance, Schober's test
, and chest expansion) were documented for each patient.
The modified lumbar Schober's test
yielded a result of 5 cm, and chest expansion during maximum inspiration was 1 cm.
The Schober's test
measurement was 2 cm, chest expansion was 2.
The total range of thoracolumbar movement in the sagittal plane was evaluated by the modified Schober's test
and finger-to-floor distance.
Other parameters were duration of morning stiffness, modified Schober's test
, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) level.
