**4.7. Limitations**

The study has a number of weaknesses. The small sample size reduced the statistical power of the study. Also, the group was not homogeneous, with different degrees of degenerative changes in the lumbar spine. This would confound the outcome, as subjects with more flexible spines are expected to have better improvement. Also, it was difficult to ensure that patients followed the exercises protocol strictly at home.

Further studies are required to elucidate whether SBP positively influences the thoracolumbar and lumbar curves in adult scoliosis patients, particularly those with curves that are susceptible to progression and whether SBP when combined with the standard conservative treatments improve their effectiveness.
