The relationship between trunk function and spasticity in people with multiple sclerosis

Abstract

Background

As People with multiple sclerosis (PWMS) experience greater disability, their ability to control their trunk diminishes, indicating that trunk control should be a focus as the disease advances. Spasticity is another complication that leads to disability in people with multiple sclerosis is spasticity. Patients who do not have proper trunk control and an inappropriate length-tension relationship have less capacity for lower extremity movements and high tonicity in the lower limb muscles.

Methods

Sixty-six women and men with multiple sclerosis between the ages of 20–50 who have moderate disability participated in this study. An evaluation of the relationship between trunk control and spasticity has been carried out. Trunk motor control was assessed using the Trunk Impairment Scale (TIS) and spasticity was assessed using the Multiple Sclerosis Spasticity Scale-88 (MSSS-88). Trunk motor control was assessed with the Trunk Impairment Scale (TIS) and spasticity with the Multiple Sclerosis Spasticity Scale 88 (MSSS-88).

Results

The MSSS-88 total score was negatively correlated with the TIS score (b = −0.011, 95% CI: 0.018 to −0.003, P = 0.006). A 1-point increase in the MSSS-88 total score was associated with a 0.011-point decrease in the TIS score.

Conclusion

It was revealed that the Trunk function was associated with spasticity in PWMS. The core function has an inverse relationship with spasticity. The better the core functions of PWMS, the less spasticity they will have.
