Abstract Background: This study aimed to describe lower limbs impairments, balance and activity limitations related to indoor mobility in adult walkers with autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS). Results: Twenty-five participants were recruited with a mean age of 32.2 (±10.4) years with 45.7 % using a walking aid. There is a significant difference between participants with and without a walking aid in terms of lower limbs coordination, balance and mobility. Although participants who walk without a walking aid perform better than the others and they are below predictive or reference values. Despite significant mobility limitations, only mild spasticity and passive range of motion limitations were observed. However, there is a significant difference between unaffected individuals and participants with ARSACS for lower limb muscle cocontraction. Conclusions: Results show a high level of lower limb impairments, balance and mobility limitation in adults’ participants with ARSACS that are still walking, including people not using a walking aid. One of the most original finding is the presence of excessive cocontraction and a relatively mild level of spasticity in the lower limbs muscles. Results of this study better circumscribes the impairments and activities that should be the focus of intervention including rehabilitation in ARSACS.

Abstract Background This study aimed to describe lower limbs impairments, balance and activity limitations related to indoor mobility in adult walkers with autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS). Results Twenty-five participants were recruited with a mean age of 32.2 (± 10.4) years with 45.7% using a walking aid.

BACKGROUND: Microsurgical flaps are widely used to treat complex traumatic wounds of upper and lower limbs. Few studies have evaluated whether the vascular changes in preoperative computed tomography angiography (CTA) influence the selection of recipient vessel and type of anastomosis and the microsurgical flaps outcomes including complications. OBJECTIVE: The aim of this study was to evaluate if preoperative CTA reduces the occurrence of major complications (revision of the anastomosis, partial or total flap failure, and amputation) of the flaps in upper and lower limb trauma, and to describe and analyze the vascular lesions of the group with CTA and its relationship with complications. METHODS: A retrospective cohort study was undertaken with all 121 consecutive patients submitted to microsurgical flaps for traumatic lower and upper limb, from 2014 to 2020. Patients were divided into two groups: patients with preoperative CTA (CTA+) and patients not submitted to CTA (CTA–). The presence of postoperative complications was assessed and, within CTA+, we also analyzed the number of patent arteries on CTA and described the arterial lesions. RESULTS: Of the 121 flaps evaluated (84 in the lower limb and 37 in the upper limb), 64 patients underwent preoperative CTA. In the CTA+ group, 56% of patients with free flaps for lower limb had complete occlusion of one artery. CTA+ patients had a higher rate of complications (p = 0.031), which may represent a selection bias as the most complex limb injuries and may have CTA indicated more frequently. The highest rate of complications was observed in chronic cases (p = 0.034). There was no statistically significant difference in complications in patients with preoperative vascular injury or the number of patent arteries. CONCLUSIONS: CTA should not be performed routinely, however, CTA may help in surgical planning, especially in complex cases of high-energy and chronic cases, since it provides information on the best recipient artery and the adequate level to perform the microanastomosis, outside the lesion area.

Background and objective: Type of physical activity may influence morphological and muscular asymmetries in the young population. However, less is known about the size of this effect when comparing various sports. The aim of this study was to identify the degree of bilateral asymmetry (BA) and the level of unilateral ratio (UR) between isokinetic strength of knee extensors (KE) and flexors (KF) among athletes of three different types of predominant locomotion in various sports (symmetric, asymmetric and hybrid). Material and methods: The analyzed group consisted of young elite athletes (n = 50). The maximum peak muscle torque of the KE and KF in both the dominant (DL) and non-dominant (NL) lower limb during concentric muscle contraction at an angular velocity of 60°·s−1 was measured with an isokinetic dynamometer. Results: Data analysis showed a significant effect of the main factor (the type of sport) on the level of monitored variables (p = 0.004). The type of sport revealed a significant difference in the bilateral ratio (p = 0.01). The group of symmetric and hybrid sports achieved lower values (p = 0.01) of BA in their lower limb muscles than those who played asymmetric sports. The hybrid sports group achieved higher UR values (p = 0.01) in both lower limbs. Conclusions: The results indicate that sports with predominantly symmetrical, asymmetrical, and hybrid types of locomotion affected the size of the BA, as well as the UR between KE and KF in both legs in young athletes. We recommend paying attention to regular KE and KF strength diagnostics in young athletes and optimizing individual compensatory exercises if a higher ratio of strength asymmetry is discovered.

Power sports have always been very popular among servicemen. This is especially evident in recent times, when such power sports, as armsport, crossfit, kettlebell lifting, powerlifting have received some development. The article presents a comparative analysis of the power capabilities of cadets who specialize in various power sports. The study involved male cadets of the 4th year of various faculties (n=53) of the Military Academy (Odessa), who in the process of training were engaged in power sports: armsport (n=12), crossfit (n=16), kettlebell lifting (n=15), powerlifting (n = 10). In addition, the results of cadets-athletes were compared with the results of cadets of the faculty of training specialists of airborne assault troops and military intelligence and special purpose, who did not attend sports sections of the academy (n=60). Analysis of the power of the cadets was carried out on the following exercises: pull-up, lifting by coup, lifting by strength on the crossbar, 24 kg kettlebell snatch, push-up on the parallel bars, push-up. The conducted researches testified to the high level of development of power qualities of cadets of all sections of academy in power sports. There was no significant difference between the results of cadets of different power sports in most exercises. It is established that the power capabilities of cadets who are engaged in various power sports are significantly better than those of cadets who are not engaged in sports. This suggests that any of the studied power sports can be an effective means of developing and improving the power opportunities of future officers of the Armed Forces of Ukraine

Abstract Objective The aim of this study is to compare the isokinetic knee muscles peak torque measurements and proprioception between the affected and intact limbs of patients with stroke, in addition to finding the correlation between knee muscles strength and lower limb function. Methods Twelve patients with stroke (mean age 64.33 ± 6.140 years), with 3 to 7 months poststroke who can walk 25 feet independently without using or using assistive devices and full passive range of motion were included in the study. Biodex isokinetic dynamometer was used for measuring isokinetic strength at 90°/s, 120°/s, and 150°/s and isometric strength at 60°/s in both flexors and extensors of the knee, whereas proprioception was measured at 45°/s knee flexion, all for affected and intact limbs. Functional measurements were assessed using the Fugl-Meyer Assessment for Lower Limb scale and Barthel Index (BI). Results The differences shown were found to be statistically significant between affected and intact limbs in isokinetic 90°/s flexion (p = 0.005), extension (p = 0.0013), and isometric at 60°/s flexion (p < 0.0001) knee muscle strengths and also the proprioception (p = 0.05). Significant positive correlation was found between isokinetic affected side knee flexion at 90°/s (r = 0.903) with BI (r = 0.704). Conclusion There is a significant difference in peak torque measurements between affected and normal lower limbs of poststroke patients, as well as a significant correlation between the knee strength and lower limb functions. Furthermore, it can also be concluded that the differences in knee proprioception between the affected and intact limbs were shown to be significant.

This study investigated the effectiveness of whole-body vibration (WBV) training incorporated into a conventional physiotherapy (PT) program (WBV-assisted training) in improving blood flow in the lower limbs and range of motion in the lower limb joints of children with myelomeningocele (MMC). A total of 31 children with MMC (7–15 years old) underwent a 6 weeks treatment program consisting of 2 weeks of conventional PT followed by 4 weeks of WBV-assisted training. The assessment comprised two parts: evaluation of lower limb joint range of motion and Doppler ultrasonography of the superficial femoral, popliteal, and anterior tibial arteries and was performed three times for each of the participants (at baseline, after 10 sessions of PT but before WBV-assisted training, and after 20 sessions of WBV-assisted training). Our results showed that WBV-assisted training significantly improved lower limb circulation in patients with MMC, increasing velocity and reducing resistivity in all tested arteries. Moreover, WBV-assisted training alleviated lower-extremity contractures, especially of the knee. Thus, WBV-assisted training is effective as an adjunctive rehabilitation program for improving functional mobility in children with MMC.

The present study examines the level of aspiration of students belonging to different streams of education and its impact on academic performance. The sample of the study consisted of 717 students (358 males and 358 females). The age range of the sample was 18 to 19 years. Tool used for measuring level of aspiration was Level of Aspiration Measure developed by Dr. Mahesh Bhargava and Prof. M A Shah. Goal Discrepancy Score is the difference between aspiration and the achievement on the same trial. The percentiles of marks obtained in the last qualifying exam were treated as an indicator of academic performance. For inferential purpose the data was treated with ANOVA and Scheffe’s test of Multiple Comparison. The findings of the study revealed that no significant difference exists between Academic Performance of students with high and low achievers belonging to Engineering and Management streams of education; however there exists significant differences between academic performances of students with high and low Level of Aspiration belonging to Law fraternity; with students showing low Level of Aspiration performing better than students with high Level of Aspiration. There exists no significant difference between academic performance of boys and girls with respect to Level of Aspiration in engineering stream. However, there exists significant difference between academic performance of boys and girls with respect to Level of Aspiration in Management and Legal streams of education. In both the streams girls outshine boys.
