IntroductionPatients with spina bifida in the lumbosacral region usually have various degrees of motor and sensory dysfunctions of the lower extremities and anal sphincter. The aim of our study was to evaluate the distribution and differences in frequencies of affected muscles, number of affected muscles and degree of neurogenic lesion between patients with spina bifida occulta (SBO) and spina bifida aperta (SBA).Material and methodsIn 100 patients with SB, 6 muscles in the lower limbs were separately analysed. Due to the number of affected muscles, we evaluated 5 groups of patients: with 1 affected muscle, 2 affected muscles, 3 affected muscles, 4 affected muscles and 5 affected muscles. Three degrees of neurogenic lesions were assessed: mild, moderate and severe.ResultsThe tibialis anterior muscle was most frequently affected in SB patients. The outer anal sphincter was frequently affected in the group of SBA patients. Single muscle affection is frequent in the group of patients with SBO, while in the group of patients with SBA, 4 muscles were significantly frequently affected. The great majority of patients (45.46%) with affected outer anal sphincter (OAS) in the group of SBO were without affection of other muscles, while for the SBA group it was for every third patient. Mild neurogenic lesion was significantly frequent in SBO patients, while severe form was significantly frequent in SBA patients.ConclusionsPatients with SBO usually present with mild to moderate clinical presentation, while multiple root involvement and severe degree of neurogenic lesion is associated more frequently with SBA.
ObjectiveMultiple Sclerosis Spasticity Scale (MSSS)-88 has been developed for self-assessment of spasticity symptoms in patients with multiple sclerosis (MS). The objective of this study was to validate MSSS-88 and evaluate the psychometric properties in patients with MS in Serbia.MethodsThe study comprised 65 MS patients with spasticity. MSSS-88 consists of 88 items grouped in eight sections. Internal consistency of the MSSS-88SR subscales was determined using Cronbach’s alpha coefficient. Test/retest reliability with an intra-class correlation coefficient (ICC) for each MSSS-88SR subscale was performed. Clinical validity of MSSS-88SR was determined by correlations with the Numeric Rating Scale (NRS) and the Modified Ashworth Scale (MAS).ResultsThe range of Cronbach’s alpha for all scales and ICC was 0.91–0.96 and 0.84–0.91, respectively. All ICCs were statistically significant (p<0.05). All evaluated subscales of MSSS-88 were significantly correlated with the NRS scale. The highest correlation coefficients were registered between the WL subscale and the EDSS and MAS, while the strongest relationship was observed between the MSS subscale and the NRS.ConclusionThe Serbian translated version of this instrument may be useful as a clinical measure for spasticity and functionality in patients with MS.
The Patient-Reported Impact of Spasticity Measure (PRISM) has been developed recently to assess the impact of spasticity on quality of life after spinal cord injury. Although PRISM may also be useful in patients with multiple sclerosis (MS), its psychometric properties in MS have not been established and PRISM is currently available only in English. The aims of this cross-sectional study were to translate PRISM into the Serbian language (PRISMSR) and examine its validity (construct, convergent, divergent) and reliability (internal consistency, test-retest reliability) in 48 patients with spasticity because of MS diagnosed at least 1 year earlier and in remission at least 3 months. PRISMSR was administered twice 3 days apart. The validity of seven PRISMSR subscales was examined against the Modified Ashworth Scale (MAS), the Numerical Rating Scale (NRS) for spasticity, sex, and education. Internal consistency was assessed with Cronbach α and test-retest reliability with intraclass correlation coefficient for agreement (ICC2,1). During the forward-backward translation, only one PRISM item required minor cultural adaption. Almost all PRISMSR scores correlated significantly with MAS and NRS scores (r=0.29-0.51, 0.001≤P≤0.043). They were all significantly higher for MAS≥2 group versus the MAS<2 group (0.003≤P≤0.035) and for the NRS≥7 group versus the NRS<7 group (0.001≤P≤0.042), except for the Social Embarrassment subscale (P=0.083). The PRISMSR scores were not significantly different between sexes (P≥0.104) or those with high school versus college degree (P≥0.139). Both Cronbach α (0.78-0.93) and test-retest ICC2,1 (0.82-0.90) were high. The original PRISM may be translated successfully into other languages. PRISMSR shows adequate validity and reliability for assessing the impact of spasticity on quality of life in patients with MS.
