This pilot study investigates the patient-reported outcomes of postoperative rehabilitation in competitive athletes, comparing supervised rehabilitation (SVR) and home-based rehabilitation (HBR). Methods: After ACLR, 60 (out of 74 screened) athletes were recruited and equally divided into HBR and SVR groups using non-probability convenience sampling, with each group comprising 15 males and 15 females. The rehabilitation outcomes in the respective groups were evaluated at 8 months using measures (Tegner Activity Scale [TAS], International Knee Documentation Committee subjective knee form [IKDC-SKF], ACL Return to Sport after Injury [ACL-RSI]) and objective parameters (isometric muscle strength, hamstring/quadricep asymmetry). RTS was evaluated at 9 months, with ACL re-injury rates recorded approximately 6 months post-RTS. Results: Both groups exhibited decreased TAS scores (HBR: 8 to 6, SVR: 8 to 7), with the SVR group demonstrating superior postoperative IKDC-SKF scores (81.82 vs. 68.43) and lower ACL-RSI scores (49.46 vs. 55.25). Isometric and isokinetic muscle strength, along with asymmetry values, was higher in the SVR group 8 months post-ACLR (p < 0.05). The SVR group showed a higher RTS rate to the same level (76.6% vs. 53.3%), while the re-injury rate was the same in both the rehabilitation groups (3.3%). Conclusions: Although both rehabilitation approaches yielded comparable outcomes, SVR may demonstrate some superior biomechanical improvements in athletes, resulting in a higher RTS rate. However, the psychological outcomes and re-injury rates did not significantly differ between the groups, emphasizing the need to address individual psychological needs during rehabilitation. Further investigation is recommended with a larger sample size to address the differences of gender among competitive athletes.

A gyógytornaellátás során eddig is általánosan alkalmazott eljárás volt a személyes alkalmak közötti otthoni gyakorlásra ösztönzés a terápia sikeressége érdekében. Ám a foglalkozásokon megtanult és begyakorolt feladatok ismétlésszáma és pontossága kérdéses az otthoni környezetben, ami csökkentheti az eredményességet, és növelheti a sérülésveszélyt. Célkitűzés: Kutatásunkban olyan megoldást teszteltünk, amely megfizethető és széles körben elérhető eszközöket, okostelefont és laptopot használ képernyőmegosztási technológia alkalmazásával. Módszer: A 3 hétig tartó vizsgálatunkban négy csoport (vizsgálati: fiatal, n = 50, életkor 25,6 ± 3,1 év; idősebb felnőttek, n = 50, életkor 74,8 ± 9,1 év; kontroll: fiatal, n = 20, életkor 26,25 ± 3,6 év; idősebb felnőttek, n = 20, életkor 70,15 ± 5,2 év) vett részt. A résztvevők feladata guggolási és térdemelési gyakorlatok végrehajtása volt egy előre meghatározott végtagszöghelyzetig. A vizsgálati csoport tagjai a végtagmozgások és szöghelyzetek nyomon követésére egy – goniométeres alkalmazással a combjukra rögzített – okostelefont és egy aktivált képernyőmegosztási funkcióval rendelkező laptopot használtak, amely valós idejű önellenőrzést tett lehetővé. Eredmények: A célszögtől való eltérés szignifikánsan csökkent (a guggolás esetében a fiataloknál 7,7°-ról 1,7°-ra, az idősebbeknél 16,4°-ról 7,3°-ra; térdemelés esetén a fiataloknál 10,8°-ról 3,2°-ra, az idősebbeknél 14,8°-ról 6,4°-ra), vagyis a gyakorlatok végrehajtása szignifikánsan pontosabb lett a vizsgálati csoportokban. Következtetés: Eredményeink azt mutatják, hogy amikor a résztvevők numerikus visszajelzést kaptak a laptop képernyőjén keresztül, akkor a gyakorlat végrehajtásának pontossága jelentősen megnőtt. Összehasonlításaink és statisztikai elemzéseink alapján összességében kijelenthetjük, hogy olyan, könnyen hozzáférhető eszközök és módszerek is felhasználhatók az otthoni mozgásszervi rehabilitáció eredményességének javításához, mint az okostelefon és a laptop.

Objective: In physical therapy, an online video analysis software that provides real-time graphic and numerical information about the patient’s movement executions without direct personal contact would mean a significant improvement in eHealth treatment. Methods: We have developed a software layer on top of OpenPose human body position estimation software that can extract the time series of angles of arbitrary body parts using the output coordinates from OpenPose processing the data recorded by two cameras simultaneously. To validate the procedure of determining the joint angles using the Openpose software we have used the Kinovea software. Results: The comparison of the determined maximal knee angle in our and the Kinovea software, which is widely used in biomechanical measurements, was not significantly different (2.03±1.06°, p<0.05) Conclusion: This indicates, that the developed software can calculate the appropriate joint angles with the accuracy that physiotherapy treatments require. As, to our knowledge no such software yet exists, with the help of this software development, therapists could control and correct the exercises in real-time, and also from a distance, and physical therapy effectiveness could be increased.

The exercise protocol was carried out among nineteen (10 female, 9 male) junior swimmers from the Hungarian National Swim Team. All athletes showed a positive orthostatic stress test right after our exercise protocol. The diastolic blood pressure was significantly lower due to the delayed-onset muscle soreness effect in the standing position after the supine position of the orthostatic stress test, in contrast to the athletes who did not experience delayed-onset muscle soreness. Furthermore, the heart rate was dysregulated in athletes with a delayed-onset muscle soreness effect when they assumed a supine position after the sustained standing position during the orthostatic stress test, in contrast to the athletes without delayed-onset muscle soreness. Interesting to note is that, in three subjects, the sustained standing position decreased the heart rate below the level of the initial supine position and six athletes experienced dizziness in the standing position, and all of these athletes were from the group that experienced delayed-onset muscle soreness. Accordingly, this study, for the first time, demonstrated that delayed-onset muscle soreness impairs orthostasis after unaccustomed fatiguing intensive acute concentric exercise with a successive isometric weight-loaded wall-sit; however, validation of this association should be investigated in a larger sample size.

Approximately 24 ankylosing spondylitis subjects and 35 age- and gender-matched control subjects were enrolled. Data analysis showed that all corneal nerve-fiber descriptives were lower in the ankylosing spondylitis group, implicating disrupted neural regeneration. Peripheral Langerhans cell density showed a negative correlation with nerve fiber descriptions. A negative correlation between tear film break-up time and corneal nerve fiber total branch density was detected. The potential role of somatosensory terminal Piezo2 channelopathy in the pathogenesis of dry eye disease and ankylosing spondylitis is highlighted in our study, exposing the neuroimmunological link between these diseases. We hypothesized earlier that spinal neuroimmune-induced sensitization due to this somatosensory terminal primary damage could lead to Langerhans cell activation in the cornea, in association with downregulated Piezo1 channels on these cells. This activation could lead to a Th17/Treg imbalance in dry eye secondary to ankylosing spondylitis. Hence, the corneal Piezo2 channelopathy-induced impaired Piezo2-Piezo1 crosstalk could explain the disrupted neural regeneration. Moreover, the translation of our findings highlights the link between Piezo2 channelopathy-induced gateway to pathophysiology and the gateway reflex, not to mention the potential role of spinal wide dynamic range neurons in the evolution of neuropathic pain and the flare-ups in ankylosing spondylitis and dry eye disease.

We examined 29 systemic lupus erythematosus patients and 29 age-matched healthy control subjects. Corneal nerve fiber density (CNFD, the number of fibers/mm2) and peripheral Langerhans cell morphology were lower (p < 0.05) in systemic lupus erythematosus patients compared to the control group. Interestingly, corneal nerve branch density, corneal nerve fiber length, corneal nerve fiber total branch density, and corneal nerve fiber area showed a negative correlation with disease duration. A negative correlation was also demonstrated between average corneal nerve fiber density and central Langerhans cell density. This is in line with our hypothesis that corneal somatosensory terminal Piezo2 channelopathy-induced impaired Piezo2–Piezo1 crosstalk not only disrupts regeneration and keeps transcription activated, but could lead to Piezo1 downregulation and cell activation on Langerhans cells when we consider a chronic path. Hence, Piezo2 containing mechanosensory corneal nerves and dendritic Langerhans cells could also be regarded as central players in shaping the ocular surface neuroimmune homeostasis through the Piezo system. Moreover, lost autoimmune neuroinflammation compensation, lost phagocytic self-eating capacity, and lost transcription regulation, not to mention autoantibodies against vascular heparin sulfate proteoglycans and phospholipids, could all contribute to the progressive fashion of dry eye disease in systemic lupus erythematosus.

This can lead to a drastic deterioration in the patient's quality of life, with the inability to support themselves. Nowadays, in addi-tion to primary treatment of the tumour, physical training of patients has become a priority in order to maintain their quality of life. One key to this is resistance training to prevent sudden muscle loss, which the patient can do alongside primary treatment, and isometric training may be one option.Objective: Our aim was to measure the activation frequency characteristics of the biceps brachii muscle in our subjects during a fatigue protocol while creating a constant controlled isometric tension in the muscle.Method: 19 healthy university students participated in our study. After determining the dominant side, the subjects' single repetition maximum was assessed using the GymAware RS tool and then 65% and 85% of this was calculated. We placed electrodes on the biceps brachii muscle and had them hold the weight at 65% and 85% until full fatigue. Immediately afterwards, subjects performed an isometric maximal contraction (Imax). The measured electromyogra-phy recordings were divided into 3 equal parts, then the first, middle and last 3 s (W1, W2, W3) were analyzed.Results: Our results show that, consistent with fatigue, at both 1RM 65% and 1RM 85% load, the activity of the low -frequency motor units increases, while the activation of the high-frequency motor units decreases.Discussion: The present study is consistent with our previous study.Conclusion: Our test protocol is not suitable for prolonged activation of high-frequency motor units because the activity of high-frequency motor units decreases over time.
