Results of Intrathecal Baclofen Treatment in Sixteen Spasticity Patients According to Four Different Measurement Scales: A Retrospective Analysis

Introduction Spasticity is a motor disorder characterized by a velocity-dependent increase in tonic stretch reflexes. It occurs as a result of overstimulation of the stretch reflex and is a component of the upper motor neuron syndrome. Intrathecal Baclofen (ITB) pump administration in patients with a diagnosis of spasticity may be a suitable option for reducing the complaints of the patients and increasing their quality of life. The aim of this study is to analyze clinically and statistically the diagnosis, treatment criteria, and post-treatment results of patients with spasticity who were treated in our clinic. Materials and Method Sixteen patients who were diagnosed with spasticity and placed on an intrathecal Baclofen pump between January 2015 and December 2020 were included in this study. An intrathecal Baclofen trial was first applied to patients who were candidates for the Baclofen pump. The spasticity levels of the patients who decided to have an intrathecal Baclofen pump were scored according to the modified Ashworth scale (MAS) and Penn spasm frequency scale (PSFS). In addition, the scaling of the patients' own conditions according to the visual analogue scale (VAS) and ambulation status according to the modified functional ambulation classification (MFAC) were recorded. All these evaluations were repeated in the preoperative, early postoperative, and follow-up periods. Results The sex distribution of the patients included in the study was equal to eight women and eight men. The age distribution was between 18 and 76. The average age was 40.62 (standard deviation ±17.79). The average preoperative modified Ashworth scale score was 3.73, and the average Penn spasm frequency scale score of the patients was 3.67. The average preoperative modified functional ambulation classification score was 1.87, and the average visual analogue scale score was 6.67. At the end of the second postoperative week, the average modified Ashworth scale score was 1.80 and the average Penn spasm frequency scale score was 1.67. The modified functional ambulation classification score was 2.60 and the visual analogue scale score was 4.58. The average follow-up period of the patients was 64 months. At the end of the follow-up periods, the average late-period modified Ashworth scale score was 1.87, and the Penn spasm frequency scale score was 1.67. The average modified functional ambulation classification score was 3.00, and the average visual analogue scale score was 4.50. Statistically, there was a significant difference between preoperative and postoperative results in both modified Ashworth scale and Penn spasm frequency scale scores (P<0.05). Modified functional ambulation classification preoperative and postoperative comparison results (P<0.05) and visual analogue scale results (P<0.05) were also statistically significant. No significant difference was found between the early postoperative period and the late postoperative period in all measurements (P=1.00). Conclusion Intrathecal Baclofen administration is one of the many treatment options for spasticity. In this way, it has been shown that greater Baclofen efficacy is achieved and its side effects are reduced. It should always be remembered that the process of this treatment is teamwork that requires the participation of more than one specialty branch. Physical therapists, neurologists, pediatricians, and neurosurgeons should be included in this teamwork.
