BACKGROUND: Head tremor poses diagnostic problems, especially when present as an isolated or predominant symptom. OBJECTIVES: To assess how maneuvers activating upper limb postural tremor can help differentiate head tremor in essential tremor (ET) from dystonic tremor (DT) in cervical dystonia. METHODS: 48 patients with head tremor (25 ET, 23 DT), underwent clinical examination and accelerometric evaluation of head and upper limb tremor during routine tremor-inducing tasks. RESULTS: While accelerometric power and clinical scores of head tremor did not significantly differ between patient groups, task-induced variations revealed distinctions. ET patients exhibited increased head tremor power and clinical scores during forward outstretched and lateral wing-beating arm positions, unlike DT patients. Coherence between head and upper limb tremor remained consistent. Tremor stability index showed no significant differences. CONCLUSIONS: Task-induced changes in head tremor could aid in distinguishing between ET and DT. Further research is needed to refine diagnostic approaches for head tremor.

BACKGROUND: Aveir DR (Abbott, Abbott Park, IL) is a dual-chamber leadless pacemaker (LP) system with distinct atrial and ventricular LPs (ALP, VLP) that communicate wirelessly to deliver atrioventricular synchronous pacing. Success rates of these implant-to-implant (i2i) transmissions have not been systematically evaluated. OBJECTIVE: This study aims to evaluate chronic i2i success rates in a clinical setting. METHODS: Patients meeting standard dual-chamber pacing indications were enrolled and implanted with dual-chamber LP systems as part of a prospective international clinical trial (Aveir DR i2i Study). The percent of successful i2i transmissions from ALP-to-VLP (A-to-V) and VLP-to-ALP (V-to-A) were interrogated from LPs in de novo patients using the device programmer at implant, discharge, and at 1, 3, and 6 months postimplant (1M, 3M, 6M). RESULTS: A total of 399 patients completed device implant and i2i diagnostic interrogation (62% male; age 69 years; 65% sinus node dysfunction, 32% atrioventricular [AV] block). Median A-to-V and V-to-A i2i success rates exceeded 90% of beats at all time-points from implant to 6M. The minority of patients with A-to-V or V-to-A i2i success in <70% of beats at implant (A-to-V: 19% of patients, V-to-A: 31% of patients) showed roughly 40% improvement by 1M, with this minority dropping to roughly 5% of patients by 6M. Improvement in i2i communication success may be attributed to reprogramming of i2i setting levels, natural changes in dominant posture, and device stabilization. CONCLUSION: Wireless implant-to-implant communication in the new dual-chamber leadless pacemaker system demonstrated successful transmissions in >90% of beats throughout the 6-month evaluation period. Communication success improved significantly over time postimplant for specific subgroups. CLINICAL TRIAL REGISTRATION: Aveir DR i2i Study, ClinicalTrials.gov ID NCT05252702.

OBJECTIVES: Chronic back pain is the most common cause of incapacity for work. The purpose of the study was to determine the effectiveness for activating the function of the deep stabilization system (DSS) in patients with chronic low back pain. METHODS: The effectiveness of three different methods was compared: Pilates method (PM), dynamic neuromuscular stabilization and balance aids on deep stabilization system function and pain perception in the lumbar spine. The group consisted of 75 patients. RESULTS: The results show differences in the effectiveness of the methods depending on the observed characteristics. The least significant differences were observed when comparing the Pilates method to balance aids. No statistically significant difference was observed in four out of five areas. The only area where a statistically significant effect of the exercise method got recorded was the intra-abdominal pressure test (p < 0.05). The lowest change was recorded in the measured values using the intra-abdominal pressure test at PM, and the highest change was recorded in Thomayer's values at dynamic neuromuscular stabilization. CONCLUSION: By comparing the three methods it was noted that each of them has its own positive reaction to the pain and the muscular apparatus. The most appropriate method to affect DSS function appears the dynamic neuromuscular stabilization (DNS) concept, where was the most significant improvement in DSS activation and the most significant reduction in chronic low back pain.

We aimed to determine the persisting effects of various exercise modalities and intensities on functional capacity after periods of training cessation in older adults. A comprehensive search was conducted across the Cochrane Library, PubMed/MEDLINE, Scopus, and Web of Science Core Collection up to March 2024 for randomized controlled trials examining residual effects of physical exercise on functional capacity in older adults ≥ 60 years. The analysis encompassed 15 studies and 21 intervention arms, involving 787 participants. The exercise and training cessation periods ranged from 8 to 43 weeks and 4 to 36 weeks, respectively. Meta-analyses were performed using change scores from before the physical exercise to after the training cessation. The effect sizes (ES) were calculated as the standardized mean differences between the intervention and control groups' change scores. Subgroup analyses and meta-regressions explored the influence of participant characteristics, the magnitude of the effect produced by the initial training program, various exercise modalities (resistance and multicomponent training) and intensities (high and low), and subdomains of functional capacity (agility, balance, standing ability, walking ability, and stair walking). The findings revealed that exercise interventions had a significant effect on preserving functional capacity after training cessation (ES = 0.87; p < 0.01). This protective effect was consistent across various exercise modalities and intensities (ES ≥ 0.67; p ≤ 0.04). The benefits obtained during the training program were positively associated with the residual effects observed after training cessation (β = 0.73; p < 0.01), while age negatively influenced the persisting adaptations (β = -0.07; p < 0.01). Current evidence suggests that exercise-based interventions, irrespective of modality and intensity, are highly effective in preventing functional declines after training cessation among older adults.

BACKGROUND: The known impairments of the cardiovascular system in Parkinson ́s disease (PD) are caused by autonomic dysfunction and manifested mainly in postural hypotension, chronotropic insufficiency, and reduced heart rate variability. Other dysfunctions, mainly stress response, arrhythmia occurrence, and heart morphology changes, are still the subject of research. OBJECTIVES: To assess the heart rate and blood pressure reaction during exercise, advanced measurements of heart volumes and mass using cardiac magnetic resonance (CMR), and occurrence of arrhythmias in PD patients. METHODS: Thirty PD patients (19 men, mean age 57.5 years) without known cardiac comorbidities underwent bicycle ergometry, electrocardiogram Holter monitoring and CMR. Exercise and CMR parameters were compared with controls (24 subjects for ergometry, 20 for CMR). RESULTS: PD patients had lower baseline systolic blood pressure (SBP) (117.8 vs. 128.3 mmHg, p < 0.01), peak SBP (155.8 vs. 170.8 mmHg, p < 0.05), and lower heart rate increase (49.7 vs. 64.3 beats per minute, p < 0.01). PD patients had higher indexed left and right ventricular end-diastolic volumes (68.5 vs. 57.3, p = 0.003 and 73.5 vs. 61.0 mL/m2 , respectively) and also indexed left and right ventricular end-systolic volumes (44.1 vs. 39.0, p = 0.013 and 29.0 vs. 22.0 mL/m2 , p = 0.013, respectively). A high prevalence of atrial fibrillation (8 subjects, 26.7%) was found. CONCLUSIONS: This novel study combining functional and structural approaches showed that PD is linked with weaker blood pressure and heart rate reaction during exercise, increased myocardial mass and heart volumes compared to controls, and a high prevalence of atrial fibrillation.

PURPOSE: The Core Outcome Measures Index (COMI) is a short, multidimensional instrument translated into several languages that covers five domains recommended in the assessment of outcome in patients with low-back and neck pain. The purpose of this study was to cross-culturally adapt the COMI from English to Czech language and to test the face and construct validity and reproducibility of its results in patients with low-back and neck pain. METHODS: Participants (n = 125) were included from primary and secondary care. The participants reported moderate pain and disability levels. All participants filled in the COMI forms before and after surgery. Descriptive statistics, Wilcoxon paired test, Crombach's alpha, principal component analysis and information entropy calculation were used. RESULTS: The instrument was successfully forward and back-translated. It can be seen that the questionnaire applied as part of our intervention study produces answers with a sufficient degree of variability and with a satisfactory degree of representation of extreme values. It can be also seen that the questionnaire can diagnose an objectively occurring change associated with the surgeon within the intervention procedure. Our other findings support the idea of ​​a possible reduction in the number of questions that measure the same latent variable. Our investigations also showed that it is possible to reduce the range of the point scale of the perception of pain to 5 degrees of intensity and thus unify the range with the other questions. CONCLUSION: The Czech COMI shows acceptable properties and is thus suitable to use as a short instrument for measuring important domains in patients with low-back and neck pain.

UNLABELLED: In this study, we investigated the effect of regular walking and its combination with manual techniques/resistance exercise. The position of the shoulder girdle was assessed using the acromion-wall distance (AD). The intervention took place twice a week for 4 weeks. A total of 88 seniors over the age of 60 successfully completed the study. The results showed a statistically significant improvement of AD in the left shoulder within the group that underwent walking combined with resistance exercise. The remaining groups did not show any statistically significant change in AD. BACKGROUND: The world population is rapidly aging; therefore, it is necessary to respond to this challenge in time. One of the typical involutional signs of old age is a hunched posture combined with a forward position of the shoulder girdle. This posture negatively impacts various bodily functions, postural stability, and strain on the musculoskeletal system. OBJECTIVES: We aimed to evaluate the effect of walking and walking combined with manual therapy/resistance exercise on scapular positioning in healthy elderly individuals. METHODS: Participants of experimental groups underwent a 4-week training session that involved walking and manual techniques/resistance training applied 2x/week. Participants of the control group maintained their usual daily habits. RESULTS: Our results showed statistically significant improvement in scapular positioning of the left shoulder in participants who underwent regular walking combined with resistance exercise training. CONCLUSIONS: These results suggest that regular walking combined with resistance training, when properly dosed, may beneficially influence scapular positioning in healthy elderly individuals.

INTRODUCTION: Patients who have sustained extensive burns frequently exhibit substantial damage to skeletal muscle and associated complications. The rehabilitation of these patients can be challenging due to the nature of the injury and the subsequent complications. Nevertheless, there is a possibility that functional proprioceptive stimulation (illusory movements) may facilitate effective rehabilitation in patients with limited physiotherapy options. Nevertheless, this approach has yet to be tested in patients with burn injuries. MATERIAL AND METHODOLOGY: A prospective, randomised, crossover trial was conducted at a burn centre in a tertiary teaching hospital. The objective was to assess the effects of illusory movements on energy metabolism, insulin sensitivity, and skeletal muscle biology in adult critically ill patients with deep burns covering 30 % or more of the total body surface area. Two 30-minute daily sessions of functional proprioceptive stimulation were administered in addition to the standard physical therapy or physical activity regimen. Subsequently, the patients proceeded to the next stage of the trial, which involved a two-week crossover period. MEASUREMENTS AND MAIN RESULTS: Daily indirect calorimetry and calculation of nitrogen balance. Skeletal muscle biopsies from vastus lateralis for high resolution respirometry and euglycemic clamps to assess whole body glucose disposal were performed three times: at baseline and then fortnightly after each intervention period. The intervention was feasible and well tolerated in both early and late stages of burn disease. It did not change energy expenditure (mean change -33 [95 % CI: -292;+227] kcal .24 h-1, p = 0.79), nitrogen balance (+2.0 [95 % CI: -3.1;+7.1] g N .1.73 m-2 BSA .24 h-1), or insulin sensitivity (mean change of insulin-mediated glucose disposal -0.33 [95 % CI: -1.18;+0.53] mmol.h-1). At the cellular level, the intervention increased the capacity of mitochondria to synthesize ATP by aerobic phosphorylation and tended to increase mitochondrial coupling. Functional capacities of fatty acid oxidation and electron transfer chain complexes I, II, and IV were unaffected. CONCLUSIONS: Compared to physical therapy alone, two daily sessions of functional proprioceptive stimulation in addition to usual physical therapy in patients with extensive burns did not change energy expenditure, insulin sensitivity, nitrogen balance, or energy substrate oxidation. At cellular level, the intervention improved the capacity of aerobic phosphorylation in skeletal muscle mitochondria. Clinical effects remain to be demonstrated in adequately powered trials.

During vertical jump evaluations in which jump height is estimated from flight time (FT), the jumper must maintain the same body posture between vertical takeoff and landing. As maintaining identical posture is rare during takeoff and landing between different jump attempts and in different individuals, we simulated the effect of changes in ankle position from takeoff to landing in vertical jumping to determine the range of errors that might occur in real-life scenarios. Our simulations account for changes in center of mass position during takeoff and landing, changes in ankle position, different subject statures (1.44-1.98 m), and poor to above-average jump heights. Our results show that using FT to estimate jump height without controlling for ankle position (allowing dorsiflexion) during the landing phase of the vertical jump can overestimate jump height by 18% in individuals of average stature and performing an average 30 cm jump or may overestimate by ≤60% for tall individuals performing a poor 10 cm jump, which is common for individuals jumping with added load. Nevertheless, as assessing jump heights based on FT is common practice, we offer a correction equation that can be used to reduce error, improving jump height measurement validity using the FT method allowing between-subject fair comparisons.

AIM: This study aimed to analyse cross-cultural differences in the prevalence of low back pain (LBP) and other back pain of general nurses in direct inpatient care in the Czech Republic (CZ) and Great Britain (GB). METHODS: The survey was used using an extended standardized Nordic Musculoskeletal Questionnaire and self-created additional questions. The data were analysed with Stata 15 using a significance level of 0.05. RESULTS: The data analysis was based on 1043 questionnaires. We identified statistically significant differences in the LBP prevalence between the respondents (CZ 93% and GB 85%) over a period of 12 months. Nurses in both countries stated a higher prevalence of LBP compared to pain in the neck, shoulders or upper back. LBP increases in relation to age, length of work experience, body mass index (BMI) and university education (BSc). Age, length of work experience, BMI and education (nursing college and master's degree) were confirmed as significant risks contributing to the increased prevalence of other back pain as well. Respondents reported a reduction in work performance, leisure activities and the need to change profession in relation to LBP. CONCLUSION: The results of the study confirm that LBP is a frequent occupational health issue in the general nurses working in direct inpatient care in both countries.
