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.

BACKGROUND: Muscle strength and postural control are essential components for performing daily living activities, particularly in older adults, and can therefore serve as screening tools for assessing fall risk in this population. METHODS: The aim of this quasi-experimental study was to evaluate the impact of a 12-week exercise intervention followed by a 2-week detraining period on lower limb strength and postural stability in older adults. The study involved 38 community-dwelling participants of Central European origin over 60 years of age. Participants underwent the measurements consisting of assessments of knee flexors and extensors strength (isokinetic dynamometer, 90° range of motion, 60°/s angular velocity, Humac Norm CSMI, Stoughton MA, USA), toe grip strength (toe grip dynamometer, Takei Scientific Instruments, Niigata, Japan), and postural stability (narrow stand, 30 s, Kistler, Switzerland). Testing was repeated three times during the study (pre-intervention, post-intervention, and post-detraining). Participants were separated into 3 groups according to the type of training: resistance training group (n = 13), proprioceptive training group (n = 14), and endurance training group (n = 11). The intervention program lasted 12 weeks, two 60-min sessions per week. A linear mixed model (LMM) predicted a change in postural stability after the resistance, proprioceptive, and endurance exercise interventions were applied. RESULTS: Results showed that knee extensor strength normalized to body mass significantly increased in the resistance training group post-intervention (p = 0.01). Toe grip strength was significantly higher after the intervention in the endurance training group (p = 0.02). A statistically significant increase in knee flexor strength was observed in the proprioceptive training group (p = 0.01). The 2-weeks detraining period revealed no statistically significant loss in training gains. The LMM found different predictions of postural stability changes related to knee extensor strength after each type of training intervention. The final LMM model explains well the variability of the dependent variable R2 = 0.866. CONCLUSIONS: These results highlight the unique characteristics of specific exercise interventions in enhancing muscular strength and postural stability, which are critical for fall prevention among older adults.

Background: Visceral manipulation is a soft tissue manual work technique that originates from and is classified within the Osteopathic Manipulative Technique (OMT), focusing on the fascial tissue mobilisation of the visceral system. Manual therapy on internal organs is based on anatomy, physiology and physics. Methods: Sixty women with endometriosis and pelvic organ prolapse, aged 41.5 ± 12.02, participated in the study. The women had manipulation therapy once a week for 5 weeks. The World Health Organisation Quality of Life BREF questionnaire and a postural stability assessment were administered before and after performing visceral manipulation. Results: The p-value = 0.0093 obtained in the group with prolapses and the p-value = 0.0001 in the group with endometriosis indicated that the applied visceral manipulation improved the women's quality of life. No effect of therapy was observed on postural stability. Conclusions: Visceral manipulation improved the quality of life of both study groups of women. A significant difference was also observed when comparing the two groups for area.

Background/Objectives: As musculoskeletal injuries in gastroenterologists related to the performance of endoscopic procedures are on the rise, solutions and new approaches are needed to prevent these undesired outcomes. In our study, we evaluated an approach to ergonomic challenges in the form of a belt-like endoscope holder designed to redistribute the weight of the endoscope across the whole body of the practitioner. The aim of the study was to determine how the use of this holder affected the body posture of practitioners during endoscopy. Methods: We designed a special endoscopic model that emulates basic endoscopic movement and maneuvers. With the use of the MoCap camera system, we recorded experienced endoscopists exercising a standardized set of tasks with and without the holder. Results: Following video and statistical analyses, the most significant differences were observed in the position of the left arm which pointed to a more relaxed arm position. Conclusions: The ergonomic benefits of the belt holder in this model merit testing in the clinical setting to evaluate its effectiveness and prevention of musculoskeletal injuries in GI endoscopy.

Background/Objectives: This case study involved a 24-year-old male with an arteriovenous malformation localized in the long head of the right biceps femoris muscle, with an anterior cruciate ligament injury. The aim was to assess the effects of a five-week kinesiological protocol, which included global postural re-education and strengthening exercises focused on knee stabilization. Methods: The effectiveness of the therapeutic intervention was evaluated using Gait Analysis, clinical examination, and the SF-36 questionnaire to assess the patient's quality of life. Results: The study revealed significant postural improvements, including the restoration of the spine's physiological curves, with kyphosis angles measuring 44.7° in indifferent orthostasis and 41.7° in self-corrected standing; and lumbar lordosis measuring 32.8° in indifferent orthostasis and 41.9° in self-corrected standing. Additionally, there was a restoration of the correct knee, hip, and ankle angles, along with a shift in the principal axis of the center of pressure from 7.6° pre-intervention to 12.9° post-intervention. The patient's perception of physical efficiency also improved, increasing from 60% to 75% over the treatment period. Conclusions: The effectiveness of the kinesiological treatment was confirmed by the improvement in gait stability and overall strengthening. The patient's active involvement in the treatment process enhanced his confidence in its success, ensuring adherence to the protocols.

Background: The aim of our pilot study was to assess the feasibility and effectiveness of individual balance telerehabilitation for people with multiple sclerosis (MS). Methods: In this pilot study 20 individuals with MS with balance impairment were included (10 in experimental, 10 in control group). The experimental group underwent 12 weeks of individual telerehabilitation (with direct synchronous contact between the physiotherapist and the patient). The control group received conventional outpatient physiotherapy. The standardized tests of balance and functional mobility were assessed at baseline and after intervention. Results: Comparing the two groups, the experimental group achieved statistically significant improvement in balance: the BBS test (p=0.002), TUG (p=0.048), functional test standing on one limb (p=0.01), and subjectively perceived balance with the ABC Scale questionnaire (p=0.041). The substantive significance (Cohen's d) when comparing the two groups reached a large effect size in the BBS (d=0.83) and standing on one limb (d=1.06) and in the MSWS-12 (d=0.78) and ABC Scale questionnaire (d=0.78). Conclusion: Telerehabilitation interventions represent an increasing trend and our data suggest that individually delivered online telerehabilitation can be effective in the treatment of balance and functional mobility disorders in MS.

BACKGROUND: Whole-body vibration (WBV) is being used in rehabilitation and sport. Studies confirm its positive impact on muscle strength and power or regulating muscle hypertension. However, there are some uncertainties regarding its influence on postural stability. This issue seems particularly interesting in the case of individuals with generalized joint hypermobility (GJH), for whom proprioceptive training and muscle strengthening exercises are recommended while techniques that decrease muscle tension are not advised. OBJECTIVE: The aim of the study was to evaluate the acute effect of WBV on postural stability in adults with GJH. METHODS: 60 participants were categorized into the groups: 1) hypermobility with vibration (GJH+WBV), 2) hypermobility without vibration (GJH-WBV), 3) control group with vibration (CTRL+WBV), 4) control group without vibration (CTRL-WBV). The first and the third group completed WBV (frequency: 15 Hz and 30 Hz, amplitude 3 mm, 3 × 3 min). The second and fourth groups participated only in measurement sessions. GJH was assessed using the Beighton test. Postural stability was measured as the overall stability index (OSI) on the Biodex Balance System on the stable and unstable platform with open and closed eyes. Measurements were taken before and after WBV for two weeks. RESULTS: At a frequency of 15 Hz, a significant time effect was observed for measurements Before and After in CTRL-WBV on the stable platform with open eyes (p= 0.012) and on the unstable platform with closed eyes (p= 0.000) for the GJH+WBV and CTRL+WBV groups. There were no significant interactions (p> 0.05) between factors. At a frequency of 30 Hz, there was a significant time effect Before and After (p= 0.047) on the stable platform with open eyes, but no interaction was found between factors (p= 0.835). CONCLUSION: There is no positive acute effect of WBV on postural stability in adults with and without GJH.

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.
