Grade-4/5 motor activity log-Brazil for post-stroke individuals with a severely impaired upper limb: a validity, reliability and measurement error study.

PURPOSE: This study examined the clinimetrics of the Brazilian-Portuguese translation of the Grade-4/5 Motor Activity Log (MAL 4/5), which assesses everyday use of the more affected upper-limb (UL) in stroke survivors with moderate/severe or severe motor impairment. MATERIALS AND METHODS: The translated MAL 4/5 was administered to 47 stroke survivors with moderate/severe or severe UL motor impairment. Accelerometers were worn on participants' wrists for five days on average prior to the first assessment. Test-retest and inter-rater reliabilities were assessed using the intraclass correlation coefficient (ICC), internal consistency using Cronbach's α, and construct validity was tested with correlations with the accelerometry. The measurement error (SEM) and the minimal detectable change (MDC) were calculated. RESULTS: MAL4/5-Brazil's test-retest reliability (AOU: ICC = 0.84; QOU: ICC = 0.90), inter-rater reliability (AOU: ICC = 0.83; QOU: ICC = 0.91), internal consistency (Cronbach's α = 0.91 and 0.95 for AOU and QOU scales, respectively), the SEM and MDC were 0.3 and 0.8 points for the AOU subscale and 0.2 and 0.5 points for the QOU subscale, respectively. The construct validity (AOU scale: r = 0.67; QOU scale: r = 0.76) was high. CONCLUSION: Grade-4/5 Motor Activity Log-Brazil is a reliable and valid instrument for assessing the more-affected UL use of stroke patients with moderate/severe or severe UL motor impairments.

Reliability and concurrent validity of the Grade-4/5 MAL-Brazil were established in adults with hemiparesis moderate/severe or severe upper extremity post Stroke.The minimum detectable change for the Grade-4/5 MAL-Brazil was 0.8 points for the Amount of Use scale and 0.5 points for the Quality of Use scale.Data from the accelerometry supports the construct validity of this instrument.The assessment can now be used clinically and for research in adults with impairment upper extremity moderate/severe or severe post Stroke.

Effectiveness of kinesio taping for chronic stroke patients: a systematic review with meta-analysis.

PURPOSE: Kinesio taping (KT) is an approach that has been used in the rehabilitation of patients with chronic stroke. The aim of this review is to evaluate the effectiveness of KT alone or combined with other interventions for patients with chronic stroke. MATERIALS AND METHODS: The search was performed on CENTRAL, EMBASE, PEDro, and five other databases and two trial registries up to July 2022. We included randomized controlled trials that evaluated the effectiveness of KT compared to control interventions. The primary outcomes were upper limb function and gait. We assessed the risk of bias in the included studies using the PEDro scale. The certainty of the evidence was assessed using the GRADE approach. RESULTS: We included 14 RCTs undertaken in six different countries. PEDro score ranged from 4 to 9 points. There is very-low certainty evidence that KT has no effect on gait, balance, and postural control. We found very-low certainty evidence of a slightly benefit when used in addition to other therapies for gait, balance and postural control, and pain intensity. CONCLUSIONS: Our study findings show KT does not have enough robust evidence for improving upper limb function, gait, balance and postural control, and pain intensity in chronic stroke patients.Implications for rehabilitationKinesio taping (KT) is a method that has gained popularity among some health professionals to treat patients poststroke.There is very-low certainty evidence that KT alone has no effect on gait, balance and postural control compared to no treatment.There is very-low certainty evidence that KT plus other therapies may be slightly beneficial for gait, balance and postural control, and pain intensity intervention.Only one study reported there were no adverse events such as skin reactions or local ulceration for patients poststroke.

Functional Outcomes Associated With Independence in Walking Among People With Hereditary Ataxias: An Exploratory Cross-sectional Study.

OBJECTIVE: This study aimed to identify functional outcomes related to independence in walking among people affected by hereditary ataxias. METHODS: Sixty participants were selected by convenience in a list provided by an organization of people with ataxia. Sociodemographic and clinical data were collected using a semistructured questionnaire. The Assessment and Rating of Ataxia was used to assess and rate cerebellar ataxia. Changes in body structure and function, limitation in activities, and restriction in participation were evaluated with specific outcome measures. Participants were classified as independent in walking if they were able to walk without walking aids or human assistance and as dependent in walking if they have been using walking aids (sticks, crutches, or walkers) for more than 6 months, using a wheelchair for locomotion most of the day, or both. Multivariate logistic regression analyses were conducted hierarchically and in blocks considering upper limbs function, balance systems, sensory functions, postural control, walking, independence, cognition, and perception as independent variables. The prevalence ratio for walking independence was determined. RESULTS: The final regression model pointed out that gait capacity assessed by the 6-Minute Walk Test and dexterity assessed by the Box and Blocks test were the main markers related to walking independence in individuals with hereditary ataxias. CONCLUSION: The distance covered in 6 minutes of walking (walking endurance) and upper extremity dexterity can be used to better assess the progression of cerebellar disease related to walking independence in individuals with hereditary ataxias. IMPACT: This study supports early detection of individuals who are at risk of loss of walking independence and an optimized rehabilitation plan.

Measurement properties of the Reaching Performance Scale for Stroke.

AIM: Reaching Performance Scale for Stroke (RPSS) evaluates the upper limb reach-to-grasp movement quality and compensatory movements. The objective of the study was to test the reliability, construct validity, and interpretability of the Brazilian-Portuguese RPSS. METHODS: Fifty-one individuals (mean age 62 ± 10.8 years), with acute-to-chronic stroke (range: 1-300 months) were video recorded while performing a reach-to-grasp task of a cone placed both close and far from the individual. Their degree of motor impairment ranged from 4 to 59 points in the Fugl-Meyer scale. RESULTS: Reaching Performance Scale for Stroke showed excellent intra- (ICC2,1 = 1.00) and interrater (ICC2,1 = 0.98-0.99) reliability, and redundant internal consistency (Cronbach's α = 0.98). The construct validity between RPSS and Fugl-Meyer scale was strong (Spearman rho = 0.88-0.89; p < 0.0001). The scale was able to discriminate individuals with mild or moderate upper limb impairment from those with severe impairment. We found ceiling and floor effects. CONCLUSIONS: Reaching Performance Scale for Stroke showed excellent reliability and redundant internal consistency. The construct validity with the Fugl-Meyer scale was strong. Reaching Performance Scale for Stroke was able to discriminate individuals with different levels of upper limb impairment.IMPLICATIONS FOR REHABILITATIONPost-stroke individuals develop compensatory strategies to perform reaching movements with the paretic upper limb.The Reaching Performance Scale for Stroke provides a quantitative and qualitative evaluation of the reach-to-grasp movement.The Reaching Performance Scale for Stroke is suitable for use with Brazilian-Portuguese speakers and has adequate reliability and validity.

Performance of discrete, reciprocal, and cyclic movements of the ipsilesional upper limb in individuals after stroke.

Aiming movements of the upper limbs can be classified either as discrete, or reciprocal, or cyclic. The control of these movements after a stroke can be affected. The aim of this experimental, cross-sectional study was to characterize the performance of these movements after the right and left hemisphere chronic stroke. Thirty-six individuals aged between 40 and 70 years, right-handed, were allocated into three groups (control, right stroke, and left stroke). Participants were asked to perform aiming movements on a tablet. Individuals after stroke performed the tasks only with their ipsilesional limb, while the control group performed movements with both limbs. The reaction and movement times, peak velocity, and the variability and error of the endpoint were analyzed. Individuals after stroke presented a worse performance in all movement classes as expected, but differently depending on the damaged hemisphere. Participants with right hemisphere damage showed larger endpoint errors, while those with left hemisphere damage had longer reaction and movement times. Both differences were seen consistently in discrete and reciprocal, but not in cyclic movements. Cyclic movements presented shorter latencies, were faster, and showed greater endpoint errors when compared to discrete and reciprocal movements. These results suggest that stroke affects differently the performance of discrete and reciprocal movements according to the hemisphere lesion side, but not in cyclic movements. Different levels of motor control among the three classes of movements by the nervous system may justify these results.

Different weekly frequencies of Pilates did not accelerate pain improvement in patients with chronic low back pain.

BACKGROUND: Recent evidence recommends Pilates for the treatment of chronic low back pain. However, it is still unknown if different weekly frequencies of Pilates can accelerate the improvement of symptoms in patients with chronic low back pain verified by a daily pain assessment. OBJECTIVE: To analyze whether different weekly frequencies of Pilates can accelerate pain reduction by 30%, 50%, and 100% in patients with non-specific chronic low back pain and the necessary number of weeks to reach these improvements. METHODS: Two hundred and twenty-two patients were randomized into three groups: Pilates group 1 received treatment once a week, Pilates group 2 received treatment twice a week, and Pilates group 3 received treatment three times a week. All groups received Pilates for six weeks. Pain intensity was measured daily before and after each intervention session using the Pain Numerical Rating Scale. The assessor was not blind. RESULTS: The survival analysis showed that all Pilates groups had a pain reduction of 30%, 50%, and 100% at the same speed during treatment. There was no difference between the different weekly frequencies of Pilates for any of the comparisons (p>0.05). After the first week of treatment, 44.6% of the patients in Pilates group 3 showed complete pain improvement, followed by 37.8% of the patients in Pilates group 2 and 29.7% in Pilates group 1. After the last week, 71.6% (Pilates group 1), 77% (Pilates group 2), and 78.4% (Pilates group 3) of the patients reported complete improvement of symptoms. CONCLUSION: Different weekly frequencies of Pilates did not accelerate pain improvement in patients with non-specific chronic low back pain.

Different doses of Pilates-based exercise therapy for chronic low back pain: a randomised controlled trial with economic evaluation.

OBJECTIVES: To evaluate the effectiveness and cost-utility of the addition of different doses of Pilates to an advice for non-specific chronic low back pain (NSCLBP) from a societal perspective. DESIGN: Randomised controlled trial with economic evaluation. SETTING: Physiotherapy clinic in São Paulo, Brazil. PARTICIPANTS: 296 patients with NSCLBP. INTERVENTIONS: All patients received advice and were randomly allocated to four groups (n=74 per group): booklet group (BG), Pilates once a week (Pilates group 1, PG1), Pilates twice a week (Pilates group 2, PG2) and Pilates three times a week (Pilates group 3, PG3). MAIN OUTCOME MEASURES: Primary outcomes were pain and disability at 6-week follow-up. RESULTS: Compared with the BG, all Pilates groups showed significant improvements in pain (PG1, mean difference (MD)=-1.2, 95% CI -2.2 to -0.3; PG2, MD=-2.3, 95% CI -3.2 to -1.4; PG3, MD=-2.1, 95% CI -3.0 to -1.1) and disability (PG1, MD=-1.9, 95% CI -3.6 to -0.1; PG2, MD=-4.7, 95% CI -6.4 to -3.0; PG3, MD=-3.3, 95% CI -5.0 to -1.6). Among the different doses, PG2 showed significant improvements in comparison with PG1 for pain (MD=-1.1, 95% CI -2.0 to -0.1) and disability (MD=-2.8, 95% CI -4.5 to -1.1). The cost-utility analysis showed that PG3 had a 0.78 probability of being cost-effective at a willingness-to-pay of £20 000 per quality-adjusted life-year gained. CONCLUSIONS: Adding two sessions of Pilates exercises to advice provided better outcomes in pain and disability than advice alone for patients with NSCLBP; non-specific elements such as greater attention or expectation might be part of this effect. The cost-utility analysis showed that Pilates three times a week was the preferred option. TRIAL REGISTRATION NUMBER: NCT02241538, Completed.

Effectiveness and Cost-Effectiveness of Different Weekly Frequencies of Pilates for Chronic Low Back Pain: Randomized Controlled Trial.

BACKGROUND: The Pilates method has been recommended to patients with low back pain, but the evidence on effectiveness is inconclusive. In addition, there is still no evidence for the cost-effectiveness of this method or for the ideal number of sessions to achieve the highest effectiveness. OBJECTIVE: The aim of this study will be to investigate the effectiveness and cost-effectiveness of the Pilates method with different weekly frequencies in the treatment of patients with nonspecific low back pain. DESIGN: This is a randomized controlled trial with blinded assessor. SETTING: This study will be conducted at a physical therapy clinic in São Paulo, Brazil. PARTICIPANTS: Two hundred ninety-six patients with nonspecific low back pain between the ages of 18 and 80 years will be assessed and randomly allocated to 4 groups (n=74 patients per group). INTERVENTION: All groups will receive an educational booklet. The booklet group will not receive additional exercises. Pilates group 1 will follow a Pilates-based program once a week, Pilates group 2 will follow the same program twice a week, and Pilates group 3 will follow the same program 3 times a week. The intervention will last 6 weeks. MEASUREMENTS: A blinded assessor will evaluate pain, quality-adjusted life-years, general and specific disability, kinesiophobia, pain catastrophizing, and global perceived effect 6 weeks, 6 months, and 12 months after randomization. LIMITATIONS: Therapists and patients will not be blinded. CONCLUSIONS: This will be the first study to investigate different weekly frequencies of treatment sessions for nonspecific low back pain. The results of this study will contribute to a better definition of treatment programs for this population.
