The Modified Ashworth Scale (MAS) is a clinical scale used to assess muscle spasticity. While the evidence indicates that the reliability of the MAS is better in the upper limb and in certain distal muscle groups, no investigation has compared the effect of limbs and muscle groups on the MAS reliability. This study aimed to evaluate the effect of limb and muscle group on the reliability of the MAS in patients with spastic hemiplegia. Thirty subjects with upper and lower limb muscle spasticity were recruited for this trial. Two female experienced physiotherapists participated in this examination of reliability, and rated each patient in a randomized order in a single session. For the intrarater reliability, the second rater repeated the test 1 week later. Shoulder adductor, elbow flexor, wrist flexor, hip adductor, knee extensor, and ankle plantar flexor were tested on the hemiplegic side. Results demonstrated moderate inter ( κ = 0.514, SE = 0.046, p < 0.001) and intrarater ( κ = 0.590, SE = 0.051, p < 0.001) reliability. For the inter and intrarater reliability, the agreement obtained for the upper and lower limb was similar. In the upper limb, the agreement between raters on the distal wrist flexor was significantly higher than the agreement on the proximal shoulder adductor. In the lower limb, there was a similar agreement between raters on the distal ankle plantar flexor and proximal hip adductor. For within rater, the agreement on the proximal and distal muscles of both limbs was not statistically significant. The Modified Ashworth Scale had moderate reliability. The limbs had no effect on the reliability. The agreement on distal wrist flexor in the upper limb was significantly higher between rater than in the proximal shoulder adductor. The agreement obtained with the MAS was not good, which questions the validity of the measurements.

To determine the extent to which the Brunnstrom recovery stages of upper limb in hemiparetic stroke patients are correlated to neurophysiological measures and the spasticity measure of Modified Modified Ashworth Scale (MMAS). A concurrent criterion-related validity study. Not applicable. Thirty patients (15 men and 15 women; mean ± SD = 58.8 ± 11.5 years) with upper limb spasticity after stroke were recruited. Wrist flexor spasticity was rated using the MMAS. The neurophysiological measures were Hslp/Mslp ratio, H(max)/M(max) ratio and Hslp. There was a significant moderate correlation between the Brunnstrom recovery stages and the neurophysiological measures. The Brunnstrom recovery stages were highly correlated to the MMAS scores (r = -0.81, p < 0.0001). The Brunnstrom recovery stages are moderately correlated with neurophysiological measures and highly correlated with the MMAS regarding the evaluation of motor recovery in stroke patients. The Brunnstrom recovery stages can be used as a valid test for the assessment of patients with post-stroke hemiplegia.

Ashworth Scales are the most widely used tests to assess the severity of muscle spasticity. These scales offer qualitative and subjective information; consequently, there are issues concerning validity and reliability. This article presents the results of a study comparing interrater reliability of the original and of the modified Ashworth Scales for measuring muscle spasticity in elbow flexors. Fifteen patients with hemiplegia (nine men and six women) with a median age of 52 years (interquartile range, 28–64) participated in this study. Two physiotherapists rated the muscle tone of elbow flexors according to ratings criteria of the Ashworth and the modified Ashworth Scales. Kappa values for the original Ashworth and the modified Ashworth Scales were 0.17 (SE = 0.21; p = 0.41) and 0.21 (SE = 0.12; p = 0.08), respectively. The scales showed similar levels of reliability (χ² = 0.0285, df = 1, p = 0.7). The Ashworth Scales are not reliable for the assessment of muscle spasticity. In the absence of interrater reliability, the validity of the measurements may also be questioned.

The objective of the study was to develop and validate a translated and culturally adapted Mini-Mental State Examination (MMSE) for the Persian-speaking population. The MMSE was translated into Persian. Two groups of neurologically intact subjects (n = 100) and subjects with Alzheimer's disease (n = 13) were studied. The difference between groups on the mean total scores of the Persian MMSE was statistically significant (control = 28.62 ± 2.09; subjects with Alzheimer's disease = 11.77 ± 5.66; p < .001). The cutoff score of 23 was the best cutoff score for our subjects with a sensitivity and specificity of 98% and 100%, respectively. There was a significant correlation between the Persian MMSE score and the level of education (r = .46) and with age (r = −.77). There was no significant correlation between the Persian MMSE and gender. The Persian MMSE was found to be valid for discrimination of cognitive impairment in the Persian-speaking community.

The Modified Modified Ashworth Scale (MMAS) is a clinical instrument for measuring spasticity. Few studies have been performed on the reliability of the MMAS. The aim of the present study was to investigate the intrarater reliability of the MMAS for the assessment of spasticity in the lower limb. We conducted a test-retest study on spasticity in the hip adductors, knee extensors, and ankle plantar flexors. Each patient was measured by a hospital-based clinical physiotherapist. Twenty-three patients with stroke or multiple sclerosis (fourteen women, nine men) and a mean +/- standard deviation age of 37.3 +/- 14.1 years participated. The weighted kappa was moderate for the hip adductors (weighted kappa = 0.45, standard error [SE] = 0.16, p = 0.007), good for the knee extensors (weighted kappa = 0.62, SE = 0.12, p < 0.001), and very good for the ankle plantar flexors (weighted kappa = 0.85, SE = 0.05, p < 0.001). The kappa value for overall agreement was very good (weighted kappa = 0.87, SE = 0.03, p < 0.001). The reliability for the ankle plantar flexors was significantly higher than that for the hip adductors. The intrarater reliability of the MMAS in patients with lower-limb muscle spasticity was very good, and it can be used as a measure of spasticity over time.

Purpose: To investigate the effect of low-frequency repetitive transcranial magnetic stimulation (rTMS) on lower extremity (LE) spasticity, motor function and motor neurone excitability in chronic stroke patients. Method: This study was a randomised sham-controlled cross-over trial with 1-week follow-up. A total of 20 post-stroke patients were randomised to receive active (n = 10) or sham (n = 10) rTMS. Fourteen of them (7 in each group) crossed over to the sham or active rTMS after a washout period of 1 month. Interventions consist of five consecutive daily sessions of active or sham rTMS to the unaffected lower extremity motor area (1000 pulses; 1 Hz; 90% of the tibialis anterior motor threshold). Outcome measures were modified modified ashworth scale (MMAS), the H-reflex, lower extremity section of Fugl–Mayer assessment (LE-FMA) and timed UP and GO (TUG) test. All outcomes were measured at three levels in each intervention period: pre- and post-intervention and 1-week follow-up. Results: Friedman’s test revealed significant improvement in MMAS score only after active rTMS. This improvement lasted for one week after the active rTMS. Repeated measure analysis of variance (ANOVA) showed significant time*intervention interaction for LE-FMA. There are no differences between groups for the MMAS and LE-FMA. No significant change in H_max/M_max ratio and TUG test was noted. Conclusion: Low-frequency rTMS over the LE motor area can improve clinical measures of muscle spasticity and motor function. More studies are needed to clarify the changes underlying this improvement in spasticity. Implications for Rehabilitation Spasticity is a common disorder and one of the causes of long-term disability after stroke. Physical therapy modalities, oral medications, focal intervention and surgical procedures have been used for spasticity reduction. Beneficial effect of the repetitive transcranial magnetic stimulation (rTMS) for post-stroke upper extremity spasticity reduction and motor function improvement was demonstrated in previous studies. This study shows amelioration of lower extremity spasticity and motor function improvement after five daily sessions of inhibitory rTMS to the unaffected brain hemisphere which lasted for at least 1 week following the intervention.
