Item Anticipatory and Compensatory Postural Adjustments in Response to External Lateral Shoulder Perturbations in Subjects with Parkinson’s Disease(2016) Swarowsky, AlessandraThe purpose of this study was to investigate the anticipatory (APA) and compensatory (CPA) postural adjustments in individuals with Parkinson’s disease (PD) during lateral instability of posture. Twenty-six subjects (13 individuals with PD and 13 healthy matched controls) were exposed to predictable lateral postural perturbations. The electromyographic (EMG) activity of the lateral muscles and the displacement of the center of pressure (COP) were recorded during four time intervals that are typical for postural adjustments, i.e., immediately before (APA1, APA2) and after (CPA1 and CPA2) the postural disturbances. The magnitude of the activity of the lateral muscles in the group with PD was lower only during the CPA time intervals and not during the anticipatory adjustments (APAs). Despite this finding, subjects with PD exhibit smaller COP excursions before and after the disturbance, probably due to lack of flexibility and proprioceptive impairments. The results of this study suggest that postural instability in subjects with PD can be partially explained by decreased postural sway, before and after perturbations, and reduced muscular activity after body disturbances. Our findings can motivate new studies to investigate therapeutic interventions that optimize the use of postural adjustment strategies in subjects with PD.Item Are Functional Mobility Tests Responsive to Group Physical Therapy Intervention in Individuals with Parkinson’s Disease?(2018) Swarowsky, AlessandraBACKGROUND: The Timed up and go test (TUG), the Five times sit-to-stand test (FTSTS) and the Bed Mobility test (BMT) are widely used in clinical practice for Parkinson Disease (PD). However, no reported studies have evaluated the responsiveness to group physical therapy intervention (GPTI). OBJECTIVE: To verify if TUG, FTSTS and BMT were responsive to GPTI. METHODS: Thirty individuals with PD were assessed prior to and after an 8-week evidence-based GPTI. Paired t test was used to determine statistically significant change pre-and post-intervention. Internal responsiveness (IR) was classified with the standardized response mean (SRM). A 5-point Likert scale assessed self-perceived performance by the subjects after the intervention. Analysis of the receiver operating characteristic (ROC) curve was used to determine the accuracy and cut-off scores for identifying participants who had shown improvement. RESULTS: GPTI was efficient in improving real (p ≤0.001) and self-perceived mobility performance in all measures. All tests were responsive to changes: the IR varied from medium to high (SRM = 0.7–1.5); the cut-off point for TUG test was >2.2 s, for FTSTS test was >2.5 s and for BM test >1.4 s. CONCLUSIONS: The TUG, FTSTS and BMT were responsive to the GPTI and accurately detected meaningful clinical changes. Our results provide an important information about the clinical application of these tests in PD individuals.Item Assessing Timed Up and Go in Parkinson's Disease: Reliability and Validity of Timed Up and Go Assessment of Biomechanical Strategies(2017) Swarowsky, AlessandraObjective: To investigate the measurement properties of the Timed Up and Go Assessment of Biomechanical Strategies (TUG-ABS) to determine its adequacy for use with individuals with Parkinson's disease. Subjects: Fifty individuals with Parkinson's disease. Design: Diagnostic accuracy. Methods: The study investigated the following properties: reliability (inter-examiner, intra-examiner, test-retest, internal consistency and minimal detectable change), construct validity, and floor and ceiling effect. Results: Considering the total score, the inter-examiner, test-retest and intra-examiner reliabilities were classified as excellent (0.95 ≤ intra-class correlation coefficient (ICC)≤0.99). The TUG-ABS presented excellent internal consistency (α = 0.98). The minimal detectable change was 3.82 points. The construct validity between the TUG-ABS and the Unified Parkinson's Disease Rating Scale (UPDRS) - part III was classified as moderate (ρ = -0.62). Significant, elevated and positive correlations were obtained between TUG-ABS and the Balance Evaluation System Test (BESTest)-VI (ρ = 0.72) and negative correlations between TUG-ABS and TUG (ρ = -0.78). The discriminant function obtained with the total score of TUG-ABS classified 60% of the individuals correctly with respect to the group (determined by the performance in TUG) to which they belonged. One-way analysis of variance (ANOVA) showed that TUG-ABS discriminated the individuals with Parkinson's disease in all stages according to Hoehn & Yahr. There was a ceiling effect of 22%. Conclusion: TUG-ABS presented adequate measurement properties in individuals with Parkinson's disease.Item Asynchronous Interprofessional Simulation to Promote the Role of Physical Therapy in Wound Management(2023) Lopez, Laura; Edgar, Cory; Radloff, Jennifer C.; Lowden-Stokely, Janice; Hawes, Stacey; Rowe, LynnItem Binary Dance Rhythm or Quaternary Dance Rhythm Which Has the Greatest Effect on Non-motor Symptoms of Individuals With Parkinson's Disease?(2021) Swarowsky, AlessandraThis study aimed to compare the effect of a binary and quaternary rhythm protocol on cognition, mental activity, daily life, and quality of life among individuals with Parkinson's Disease. A two-arm randomized clinical trial with 31 individuals diagnosed with Parkinson's disease, who were allocated to the binary group or quaternary group. Both groups underwent a 12-week intervention. The following variables were analyzed: personal and clinical information; MoCA; UPDRSI and II; PDQ-39. Both intervention groups improved cognition, mental activity, activities of daily living, and quality of life. In addition, there were intergroup differences in total UPDRSII, writing, and hygiene where the quaternary group was superior to the binary group. It concludes that the binary and quaternary rhythm positively influenced and presented similar effects on the complementary treatment of individuals with Parkinson's disease on the studied variables. Thus, it is believed that both interventions are possible and feasible for the health professionals involved in the area.Item Body Surface Posture Evaluation: Construction, Validation and Protocol of the SPGAP System (Posture Evaluation Rotating Platform System)(2016) Swarowsky, AlessandraBackground Several posture evaluation devices have been used to detect deviations of the vertebral column. However it has been observed that the instruments present measurement errors related to the equipment, environment or measurement protocol. This study aimed to build, validate, analyze the reliability and describe a measurement protocol for the use of the Posture Evaluation Rotating Platform System (SPGAP, Brazilian abbreviation). Methods The posture evaluation system comprises a Posture Evaluation Rotating Platform, video camera, calibration support and measurement software. Two pilot studies were carried out with 102 elderly individuals (average age 69 years old, SD = ±7.3) to establish a protocol for SPGAP, controlling the measurement errors related to the environment, equipment and the person under evaluation. Content validation was completed with input from judges with expertise in posture measurement. The variation coefficient method was used to validate the measurement by the instrument of an object with known dimensions. Finally, reliability was established using repeated measurements of the known object. Results Expert content judges gave the system excellent ratings for content validity (mean 9.4 out of 10; SD 1.13). The measurement of an object with known dimensions indicated excellent validity (all measurement errors <1 %) and test-retest reliability. A total of 26 images were needed to stabilize the system. Participants in the pilot studies indicated that they felt comfortable throughout the assessment. The use of only one image can offer measurements that underestimate or overestimate the reality. To verify the images of objects with known dimensions the values for the width and height were, respectively, CV 0.88 (width) and 2.33 (height), SD 0.22 (width) and 0.35 (height), minimum and maximum values 24.83–25.2 (width) and 14.56 – 15.75 (height). In the analysis of different images (similar) of an individual, greater discrepancies were observed in the values found. The cervical index, for example, presented minimum and maximum values of 15.38 and 37.5, a coefficient of variation of 0.29 and a standard deviation of 6.78. Conclusions The SPGAP was shown to be a valid and reliable instrument for the quantitative analysis of body posture with applicability and clinical use, since it managed to reduce several measurement errors, amongst which parallax distortion.Item Brain-Computer Interface for Motor Rehabilitation(Springer, 2019) Clark, Elizabeth; Korostenskaja, MilenaItem Brazilian Samba Protocol for Individuals with Parkinson’s Disease: A Clinical Non-randomized Study(2017) Swarowsky, AlessandraBackground: In the 10 most populated countries in the world, Parkinson's disease (PD) affects more than 5 million individuals. Despite optimal treatment options already developed for the disease, concomitant involvement of other areas of health care plays an important role in complementing the treatment. From this perspective, dancing can be viewed as a non-drug alternative that can reduce falls by improving some motor skills, such as mobility, balance, gait, and posture, and can also improve the overall quality of life. Brazilian samba promotes improvement in motor and non-motor symptoms in individuals with PD, providing a new treatment option for this population. Objective: The main objective of this quasi-experimental study is to provide a 12-week samba protocol (2x/week) for individuals with PD and to compare its effects with the group without intervention. The hypothesis is that the Brazilian samba protocol will promote improvement in primary (motor) and secondary (non-motor) outcomes in individuals with PD. Methods: The sample will be selected at random from individuals diagnosed with PD in the city of Florianopolis (SC, Brazil). Sample size calculation was performed with the G*Power 3.1.9.2 software, with 0.447 effect size, at 5% significance level, power of 0.9, and test and sample loss of 20%. This yielded 60 individuals divided between the intervention and control groups. The questionnaires will be filled out before and after the dance intervention. The data collection for the control group will be held simultaneously to the intervention group. The classes will last for 1 hour, twice a week in the evening for 12 weeks, and all classes will be divided into warm-up, main part, and relaxation. Two-way analysis of variance with repeated measures and Sidak post-hoc comparison test will be used for a comparative analysis of the final results of the control group with the experimental group and of the within-group changes between pre- and postintervention period. Results: We expect to complete follow-up in September 2017. Conclusions: The major inspiration for this study was to encourage the creation of new rehabilitation programs that do not emphasize doctor involvement. This is a unique protocol for PD and we believe it can be an important tool to alleviate the motor and non-motor symptoms of individuals with PD. Dance is a simple activity depending on little equipment and few financial resources, facilitating its implementation and improving the cost-benefit relationship. In addition, activities that have a cultural aspect for the population in question, and which are pleasant, enable the participants to commit long term. This can enhance patient’s compliance with the therapy, which is often a problem for many rehabilitation programs.Item Central Nervous System Acting Drugs in Treatment of Migraine Headache(2012) Samsam, MohtashemMigraine is a primary headache disorder with an unknown pathophysiology. The growing evidence in recent years indicates migraine being a brain disorder, a sensory dysmodulation, and a system failure of normal sensory processing of the brainstem that involves the vascular tone and pain. At the moment, triptan family and NSAIDs are the first choice drugs for the treatment of acute migraine. There are several prophylactic drugs including the antiepileptic drugs (AEDs), betablockers, and Ca2+ channel blockers that are used for the treatment of migraine. Although many drugs including the triptans, NSAIDs, and others target the peripheral sites of activation, several novel drugs are being developed to target neural sites of action in the central nervous system (CNS). The first trigeminal synapses in the brain stem as well as the ascending and descending pathways and higher brain centers are involved in the transmission of pain and therefore be the main targets of several drugs some of which are in clinical trials. Central sensitization may also aggravate the headache and some drugs tend to alleviate pain by targeting neurotransmitters, receptors, or signalling molecules involved in this phenomenon. This article discusses the CNS acting novel drugs and those that are currently in use for the treatment of migraine.Item Comparison between Two Functional Mobility Scales for Parkinson's Disease Directly Applied to Physical Therapy Practice: Cross-cultural Adaptation and Measurement Properties(2017) Swarowsky, AlessandraThe Modified Parkinson Activity Scale (PASm) and Lindop Parkinson's Disease Mobility Assessment (LPA) scales were developed to assess the functional mobility in patients with Parkinson's disease (PD) being directly applied to physical therapy practice. To translate and perform the cross-cultural adaptation of PASm and LPA scales to Portuguese-Brazil, and to analyze some psychometric properties. Cross-cultural validation study. Clinical environment. Thirty-two Brazilian subjects with Parkinson's disease. The study consisted of two stages: 1) cross-cultural adaptation process; 2) evaluation of psychometric properties. Considering the total score, the interrater and test-retest reliabilities showed a coefficient of intra-class correlation that ranged between 0.97 and 0.98. Both scales showed excellent internal consistency (α=0.83 and 0.94). Positive correlations were obtained between the Brazilian versions of the LPA and PASm and PAS (ρ=0.63 and 0.92). The concurrent validity between scales and part III of UPDRS, established a moderate negative correlation, (ρ=-0.54 and -0.65). The one way ANOVA showed that LPA-Brazil discriminates the individual with PD between all stages according HY, and the PASm- Brazil between mild and severe stages, and moderate and severe. The MDC of scales ranging from 1 to 2 points. There was Ceiling effect only for the LPA-Brazil. Brazilian versions of PASm and LPA are valid and reliable instruments to assess the functional mobility in patients with PD, being directly applied to physical therapy clinical practice. The major goal of physical therapy in PD is to maintain functional mobility and independence of the patient. The results of study are relevant and could improve the physical therapy practice in Brazil, since it provides the Brazilian version of two mobility scales (one of them recommended by the European Guidelines for Physical Therapy Practice in patients with Parkinson disease).Item Concordance and Discordance Between Measured Balance and Perceived Balance and the Effect on Gait Speed and Falls Following Stroke(2016) Liphart, JodiObjective: To ascertain the existence of discordance between perceived and measured balance in persons with stroke and to examine the impact on walking speed and falls. Design: A secondary analysis of a phase three, multicentered randomized controlled trial examining walking recovery following stroke. Subjects: A total of 352 participants from the Locomotor Experience Applied Post-Stroke (LEAPS) trial. Methods: Participants were categorized into four groups: two concordant and two discordant groups in relation to measured and perceived balance. Number and percentage of individuals with concordance and discordance were evaluated at two and 12 months. Walking speed and fall incidence between groups were examined. Main measures: Perceived balance was measured by the Activities-Specific Balance Confidence scale, measured balance was determined by the Berg Balance Scale and gait speed was measured by the 10-meter walk test. Results: Discordance was present for 35.8% of participants at two months post stroke with no statistically significant change in proportion at 12 months. Discordant participants with high perceived balance and low measured balance walked 0.09 m/s faster at two months than participants with concordant low perceived and measured balance (p < 0.05). Discordant participants with low perceived balance and high measured balance walked 0.15 m/s slower than those that were concordant with high perceived and measured balance (p ⩽ 0.0001) at 12 months. Concordant participants with high perceived and measured balance walked fastest and had fewer falls. Conclusions: Discordance existed between perceived and measured balance in one-third of individuals at two and 12 months post-stroke. Perceived balance impacted gait speed but not fall incidence.Item Cross Cultural Adaptations and Sychometric Domains of Brazilian Version of PROFILE PD for Parkinson’s Disease(2017) Swarowsky, AlessandraPurpose: The PROFILE PD scale was developed specifically to evaluate patients with Parkinson’s disease (PD) within the context of the International Classification of Functioning, Disability and Health, directly applied to physical therapy practice. The study aimed to translate and cross-culturally adapt the PROFILE PD scale to Portuguese-Brazil, and to analyze its psychometric domains. Methods: Fifty participants with PD participated in the study. We assessed the clarity of the Brazilian version of the scale by physiotherapists, presence of floor and ceiling effects, interrater and test–retest reliabilities, in addition to discriminant, concurrent (UPDRS) and construct validity, internal consistence, minimal detectable change (MDC), and responsiveness. Results: The scale was considered highly clear for physical therapists. The interrater ICC was 0.74 and Wk was 0.89 for the total score. For test–retest reliability, the total ICC score was 0.99. The analysis of concurrent validity showed the Spearman correlation between Brazilian version of PROFILE PD and UPDRS (ρ = 0.77; p < 0.001). Factor analyses demonstrated that the test comprises a single scale. Brazilian version of PROFILE PD was able to discriminate the subject with PD in mild and moderate stages, and in mild and severe stages. A high internal consistency was found (α = 0.99). MDC was 2.41 points and there were no floor and ceiling effects. Also, the scale was responsive to physical therapy intervention, with improvement in 8 points after two months (effect size = 0.85). Conclusion: The Brazilian version of PROFILE PD is an instrument reliable, valid, and responsive to physical therapy intervention, that can be used to quantify impairments and limitations in patients with PD and can provide an overall summary of the impact of disease, useful for physiotherapy practice. Implications for Rehabilitation • PROFILE PD is a reliable and valid instrument to be applied in Brazilian Parkinson disease patients. • This scale is design specially to be used in physical therapy practice within the contexts surrounding the International Classification of Functioning, Disability and Health. • PROFILE PD was able to discriminate between patients in mild and moderate stages of disease which is difficult in clinical practice mainly because the scale used for this relies on balance and gait rather than a global profile.Item Dance Rhythms Improve Motor Symptoms in Individuals With Parkinson's Disease: A Randomized Clinical Trial(2022) Swarowsky, AlessandraBackground: Evidence-based practices involving dance modalities found in binary (two-beat rhythm) or quaternary (four-beat rhythm) show that dance positively influences the motor aspects of disease. Aim: This randomized clinical trial aimed to analyze the effect of two dance rhythm (binary and quaternary) on the balance, gait, and mobility in individuals with Parkinson's disease (PD). Methods: Thirty-one individuals with PD were randomized into the binary group (n = 18) and the quaternary group (n = 13). Both groups participated in different dance rhythms lasting 12 weeks, twice a week, for 45 minutes. Results: The binary group showed a significant difference in balance (p = 0.003), freezing of gait (p = 0.007), as well as in the motor aspects of MDS-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), with emphasis on the total values with a score change of 3.23. In the quaternary group, significant differences were found in balance (p = 0.021) with a score change of -2.54 and in the motor aspects of the MDS-UPDRS Part III where the total values stood out with a change of 3.54. Discussion: When comparing the possible effects of binary and quaternary rhythms on the motor symptoms of individuals with PD, it was demonstrated that binary rhythm improved balance, freezing gait, and UPDRSIII. As for the quaternary rhythm, the benefits were in balance and the UPDRSIII. Conclusion: The binary and the quaternary rhythm dance protocols positively influenced the motor symptoms of individuals with PD after 12 weeks of intervention.Item Differential Diagnosis of Deep Gluteal Pain in a Female Runner with Pelvic Involvement: A Case Report(2013) Podschun, LauraBackground: Gluteal injuries, proximal hamstring injuries, and pelvic floor disorders have been reported in the literature among runners. Some suggest that hip, pelvis, and/or groin injuries occur in 3.3% to 11.5% of long distance runners. The purpose of this case report is to describe the differential diagnosis and treatment approach for a patient presenting with combined hip and pelvic pain. Case description: A 45-year-old female distance runner was referred to physical therapy for proximal hamstring pain that had been present for several months. This pain limited her ability to tolerate sitting and caused her to cease running. Examination of the patient’s lumbar spine, pelvis, and lower extremity led to the initial differential diagnosis of hamstring syndrome and ischiogluteal bursitis. The patient’s primary symptoms improved during the initial four visits, which focused on education, pain management, trunk stabilization and gluteus maximus strengthening, however pelvic pain persisted. Further examination led to a secondary diagnosis of pelvic floor hypertonic disorder. Interventions to address the pelvic floor led to resolution of symptoms and return to running. Outcomes: Pain level on the Visual Analog Scale decreased from 7/10 to 1/10 over the course of treatment. The patient was able to return to full sport activity and improved sitting tolerance to greater then two hours without significant discomfort. Discussion: This case suggests the interdependence of lumbopelvic and lower extremity kinematics in complaints of hamstring, posterior thigh and pelvic floor disorders. This case highlights the importance of a thorough examination as well as the need to consider a regional interdependence of the pelvic floor and lower quarter when treating individuals with proximal hamstring pain.
