UNASSIGNED: The Active Movement Scale (AMS) is a brief screen for identifying movement impairments affecting functional task performance.
UNASSIGNED: To assess inter-rater reliability, test-retest reliability, floor and ceiling effects, and concurrent validity of the AMS in adults with musculoskeletal disorders.
UNASSIGNED: Fifty-five subjects (mean age: 61.3±15.3 years) transitioning from physical therapy attended two sessions. The 14-item AMS was assessed by two therapists, resulting in a total score (AMST) and two sub-scores: upper body (AMSU) and lower body (AMSL). Moreover, subjects completed PROMIS Physical Function-10a (PPF), Lifestyle Physical Function (LPF), Cardio Activity Level (CAL) surveys, Two Square Agility Test (TSAT), WorkAbility Rate of Manipulation Turning (WRMT) and Placing (WRMP), Grip Strength (GS), 10-Meter Walk Usual (GSU) and Fast (GSF) pace, and Grooved Pegboard Placing (GPP) and Remove (GPR) tests.
UNASSIGNED: Inter-rater reliability coefficients for AMST, AMSU, and AMSL were 0.96, 0.92, and 0.96, respectively, with individual item reliability ranging from 0.58 to 1.0. Test-retest reliability for these assessments yielded coefficients of 0.93, 0.84, and 0.94, with individual item reliability ranging from 0.47 to 0.88. No floor effects were observed, but mild ceiling effects were noted. AMST showed a high correlation with LPF (r = 0.72) and moderate correlation with PPF (r = 0.64) surveys. AMSU had moderate correlations with GPP (r = 0.61) and WRMP (r = 0.57) tests, while AMSL correlated moderately with GSF (r = 0.55) and TSAT (r = 0.50) tests.
UNASSIGNED: This study provides evidence of the reliability and validity of AMS in adults with musculoskeletal disorders to support transitions between rehabilitation and fitness programs.

OBJECTIVE: We aimed to elicit scientific evidence on the cost-effectiveness of two catechol-O-methyltransferase inhibitors (COMT-i) versus no COMT-i in patients with advanced Parkinson\'s disease.
METHODS: A mixed model of the decision tree and a Markov model with three health states by OFF-time level (<25%, ≥25%, and death) was constructed to compare opicapone (OPC), entacapone (ENT), and no COMT-i over a lifetime. A hypothetical cohort of 10,000 patients was created and simulated based on the characteristics of the BIPARK trial subjects.
RESULTS: Two COMT-i (OPC and ENT) were identified as a cost-effective option compared to no COMT-i. Probabilistic sensitivity analysis showed that over 90% of the simulations proved the robust cost-effectiveness of COMT-i. When the time horizon as the most influential factor decreases to a 5- and 10-year period, COMT-i can be a cost-saving option. Although ENT may be the preferred option over OPC economically because of its lower price, OPC can be acceptable if the drug price is reduced by 17%.
CONCLUSIONS: Add-on treatment with COMT-i in patients with PD receiving levodopa/carbidopa appears to be cost-saving compared with not using COMT-i. In the future, it is necessary to evaluate the economic evaluation of COMT-i based on long-term real-world evidence.

UNASSIGNED: To compare the dopamine transporter (DAT) density with other risk factors for L-DOPA-induced dyskinesia (LID) in patients with Parkinson\'s disease (PD), with and without LID.
UNASSIGNED: We evaluated 67 subjects: 44 patients with idiopathic PD of varying degrees of severity (PD group), and 23 healthy age-matched volunteers (control group). Among the 44 patients in the PD group, 29 were male and the following means were recorded at baseline: age, 59 ± 7 years; disease duration, 10 ± 6 years; Hoehn and Yahr (H&Y) stage, 2.16 ± 0.65; and Unified Parkinson\'s Disease Rating Scale part III (UPDRS III) score, 29.74 ± 17.79. All subjects underwent 99mTc-TRODAT-1 SPECT. We also calculated specific uptake ratios or binding potentials in the striatum.
UNASSIGNED: The DAT density in the ipsilateral and contralateral striata was lower in the PD group. The variables disease duration, L-DOPA dosage, doses per day, L-DOPA effect duration time, H&Y stage, and UPDRS III score explained the occurrence of LID. The DAT density in the ipsilateral striatum, contralateral striatum, and caudate nucleus was lower in the patients with LID than in those without.
UNASSIGNED: Our findings suggest that presynaptic dopaminergic denervation is associated with LID in individuals with PD.
UNASSIGNED: Comparar a densidade do transportador de dopamina (DAT) com outros fatores de risco para discinesia induzida pela L-DOPA em pacientes com doença de Parkinson, com e sem discinesias.
UNASSIGNED: Sessenta e sete sujeitos, 23 voluntários saudáveis e 44 pacientes pareados por idade com diferentes graus de gravidade da doença de Parkinson idiopática (29 homens; idade média ± desvio-padrão (DP), 59 ± 7 anos; duração média ± DP dos sintomas, 10 ± 6 anos; H&Y: média ± DP, 2,16 ± 0,65; UPDRS III: média ± DP, 29,74 ± 17,79). Todos os sujeitos realizaram SPECT cerebral com 99mTc-TRODAT-1. Além disso, foram calculadas as taxas de captação específica ou potenciais de ligação no estriado.
UNASSIGNED: A densidade de DAT do estriado ipsilateral ou contralateral foi menor no grupo doença de Parkinson. As variáveis duração da doença, dosagem de L-DOPA, doses por dia, tempo de duração do efeito da L-DOPA, H&Y e UPDRS III explicaram a ocorrência de discinesia. Adicionalmente, pacientes com discinesia exibiram menor densidade de DAT no estriado ipsilateral ou contralateral e no núcleo caudado do que os pacientes sem discinesia.
UNASSIGNED: O presente estudo sugere que a denervação dopaminérgica pré-sináptica na doença de Parkinson está associada ao desenvolvimento de discinesia induzida pela L-DOPA.

BACKGROUND: Dyskinesia is one of the most common complications of stroke. Acupuncture therapy (AT) and mirror therapy (MT) are promising rehabilitation measures for the treatment of post-stroke dyskinesia. Although some studies suggested that AT and MT are effective and safe for dyskinesia, the effects, and safety remain uncertain due to lacking strong evidence. The purpose of this study is to investigate the efficacy and safety of AT combined with MT in the treatment of post-stroke dyskinesia.
METHODS: We searched the following databases: PubMed, Web of Science, Cochrane Library, EMBASE, Medline, China Knowledge Network, WANFANG, and China Biomedical Literature Database, from inception to 1 January 2023 to identify eligible studies. Total effective rate, the Fugl-Meyer assessment scale (FMA) upper and lower limb scores, modified Barthel index scores, Berg balance scale, modified Ashworth scale, and adverse reactions were adopted as outcome indicators. The Grading of Recommendations Assessment Development and Evaluation system was used by 2 independent reviewers to assess the quality of evidence for the outcome indicators included in the study. The statistical analysis was conducted by RevMan V.5.4 software.
RESULTS: A total of 24 randomized controlled studies included 2133 patients with post-stroke dyskinesia were included. The total effective rate of AT combined with MT was more advantageous in the treatment of post-stroke dyskinesia (relative risk = 1.31, 95% confidence interval [CI] [1.22-1.42], Z = 6.96, P < .0001). AT combined with MT was more advantageous for FMA upper limb score (mean difference [MD] = 6.67, 95% CI [5.21-8.13], Z = 8.97, P < .00001) and FMA lower limb score (MD = 3.72, 95% CI [2.81-4.63], Z = 7.98, P < .00001). Meta-analysis showed that AT combined with MT for post-stroke dyskinesia had a more advantageous modified Barthel index score (MD = 9.51, 95% CI [7.44-11.58], Z = 9.01, P < .00001).
CONCLUSIONS: AT combined with MT is effective in improving motor function and daily living ability of patients, especially in improving muscle spasms. However, these results should be regarded with caution given the low quality of evidence for the evaluation results.

OBJECTIVE: Understanding how the main scapular muscles behave in overhead athletes with scapular dyskinesis (SD).
METHODS: Systematic Review.
METHODS: Electronic searches were performed in Pubmed (MedLine), Embase, CINAHL, and SPORTDiscus databases.
METHODS: Overhead athletes with SD.
METHODS: Electromyographic activity of the upper (UT), middle (MT), and lower (LT) trapezius, and serratus anterior (SA).
RESULTS: Eight studies were included in this review. The UT activity showed a tended to increase its activity mainly during tasks over 90° compared to 45°. SA activity had similar behavior, mainly during isometric tasks. The MT also increased its activity mainly in tasks with overhead angulations when compared to lower angulations. The LT activation tended to decrease its EMG activity at angulations below 60° in overhead athletes with SD.
CONCLUSIONS: The EMG behaviour of UT and SA for non-athletes appears to differ from what has already been described in the literature. The MT seems to be the most neglected muscle for scapular stabilization in overhead athletes with SD. The decrease in LT activity suggests that this may have implications for the performance of these athletes.

BACKGROUND: Scapular dyskinesis is prevalent among asymptomatic athletes, particularly those involved in overhead activities, and can significantly impact their neuromuscular control. These changes may impair upper extremity function and strength, elevating the risk of injury. Therefore, it is imperative to investigate how scapular dyskinesis affects shoulder proprioception, upper extremity dynamic stability, and hand grip strength in overhead athletes. This study compared these parameters between overhead athletes with and without scapular dyskinesis.
METHODS: The study included twenty asymptomatic professional overhead athletes with scapular dyskinesis and twenty without scapular dyskinesis, identified using the lateral scapular slide test. In this cross-sectional study, shoulder active joint position sense, serving as shoulder proprioception, was measured using an isokinetic dynamometer. Upper extremity dynamic stability and hand grip strength were evaluated using an upper quarter modified star excursion balance test (UQ-mSEBT) and a handheld dynamometer.
RESULTS: The study found that the shoulder active joint position sense was significantly lower in the scapular dyskinesis group compared to the group without scapular dyskinesis (PExternal Rotation = 0.003, PInternal Rotation < 0.001, and PForward Flexion = 0.002). However, the two groups had no significant differences in UQ-mSEBT and hand grip strength scores.
CONCLUSIONS: The results showed that scapular dyskinesis could affect the sense of shoulder active joint position among asymptomatic overhead athletes. However, it did not affect their upper extremity dynamic stability and hand grip strength.

OBJECTIVE: Scapular dyskinesis is one of the causes of shoulder disorders and involves muscle weakness in the serratus anterior. This study investigated whether motor unit (MU) recruitment and firing property, which are important for muscle exertion, have altered in serratus anterior of the individuals with scapular dyskinesis.
METHODS: Asymptomatic adults with (SD) and without (control) scapular dyskinesis were analyzed. Surface electromyography (sEMG) waveforms were collected at submaximal voluntary contraction of the serratus anterior. The sEMG waveform was decomposed into MU action potential amplitude (MUAPAMP), mean firing rate (MFR), and recruitment threshold. MUs were divided into low, moderate, and high thresholds, and MU recruitment and firing properties of the groups were compared.
RESULTS: High-threshold MUAPAMP was significantly smaller in the SD group than in the control group. The control group also exhibited recruitment properties that reflected the size principle, however, the SD group did not. Furthermore, the SD group had a lower MFR than the control group.
CONCLUSIONS: Individuals with scapular dyskinesis exhibit altered MU recruitment properties and lower firing rates of the serratus anterior; this may be detrimental to muscle performance. Thus, it may be necessary to improve the neural drive of the serratus anterior when correcting scapular dyskinesis.
