Introduction: Sockets and interfaces are important elements for lower limb orthoses and prostheses, as they allow for proper contact and fit between the devices and the affected limb or stump.Objective: To review the different polymers used in the development of lower limb sockets and external prosthetic and orthotic interfaces, their functional requirements and the possible skin problems caused by their use.Materials and methods: A literature review was conducted using the databases EBSCO, Embase, LILACS, SciELO, ScienceDirect and Scopus.Results: 47 articles and papers that met the inclusion criteria were retrieved. Thermoplastics, thermosets, foams, gels and elastomers are among the polymers used for manufacturing prosthetic and orthotic interfaces and sockets. However, studies estimate that between 32% and 90.9% of the population that use these devices have experienced skin problems on the affected stump or limb, such as excessive sweating, wounds and irritation.Conclusion: There is a clear need for further research to develop prosthetic and orthotic interfaces and sockets for lower limbs that can prevent or control damage to the skin of users.

Aims In recent years there has been a significant rise in the popularity of muscle gun devices. However, the current research regarding handheld muscle gun devices is unclear. Therefore, this literature review will explore the current literature regarding the effect of muscle gun device on lower limb range of motion, muscle activation, force output and the possibility of reducing delayed onset muscle soreness. Methods Four databases were used along with two academic search engines to search for studies that satisfied the inclusion criteria. To fulfil the inclusion criteria studies had to be of a pre-post design with a focus on the use of percussion massage devices on lower limbs. Studies exploring range of motion and muscle force output were of particular interest. Results Thirty-nine included studies were used in this literature review. It was found that handheld percussive massage devices are the most effective method of increasing lower limb range of motion compared to foam rolling and other self-myofascial protocols. The use of handheld percussive massage devices directly after exercise reduces delayed onset muscle soreness. However, there was no reported significant increase in muscle activation or force output following the usage of a handheld percussive massage device. Conclusion The use of muscle gun devices is recommended as part of a structured warm-up pre-exercise due to an increase in range of motion, reduction in perceived muscle soreness whilst having no negative impact on muscle activation and force output. Muscle guns may also be implemented as part of a rehabilitation programme post injury due to their ability to increase range of motion and reduce perceived pain and muscle soreness.

For many years, mainly to simplify data analysis, scientists assumed that during a gait, the lower limbs moved symmetrically. However, even a cursory survey of the more recent literature reveals that the human walk is symmetrical only in some aspects. That is why the presence of asymmetry should be considered in all studies of locomotion. The gait data were collected using the 3D motion analysis system Vicon. The inclusion criteria allowed the researchers to analyze a very homogenous group, which consisted of 54 subjects (27 women and 27 men). Every selected participant moved at a similar velocity: approximately 1,55 m/s. The analysis included kinematic parameters defining spatio-temporal structure of locomotion, as well as angular changes of the main joints of the lower extremities (ankle, knee and hip) in the sagittal plane. The values of those variables were calculated separately for the left and for the right leg in women and men. This approach allowed us to determine the size of the differences, and was the basis for assessing gait asymmetry using a relative asymmetry index, which was constructed by the authors. Analysis of the results demonstrates no differences in the temporal and phasic variables of movements of the right and left lower limb. However, different profiles of angular changes in the sagittal plane were observed, measured bilaterally for the ankle joint.

BACKGROUND: Several reviews have been published regarding quality of life (QoL) and Health Status (HS) in persons with lower limb amputation (LLA). However, little has been discussed in the literature with respect to older populations (i.e. age>60 years) with trans-tibial amputation. Furthermore, the perceived satisfaction with prosthesis is another important aspect for consideration in the amputees’ life. OBJECTIVE: The purpose of this review was to evaluate the impact of trans-tibial amputation on the QoL, HS and prosthesis satisfaction, in order to determine the appropriate intervention to improve these aspects in older population of trans-tibial amputees (TTA). METHODS: Research articles, published between January 2000 to March 2019, were found using Scopus, PubMed and Google Scholar databases. The methodological quality of the selected articles was assessed using the Critical Review Form-Quantitative Studies checklist. RESULTS: Ten articles that met the inclusion criteria were selected. In these papers, we can summarize that people with trans-tibial amputation have a better QoL compared to those with above knee amputation. Moreover, physical functioning and mobility are the most influencing factors for QoL and HS in older people with lower limb amputation. Finally, the prosthesis weight reduction may improve satisfaction with the prosthetic limb. CONCLUSION: Efforts have to be made in order to improve mobility in older population with transtibial amputation for better QoL and HS. This can be accomplished by means of adequate rehabilitation, pain management and an accurate choice of appropriate prosthetic components. We observed that the quality of evidence in the literature available is inadequate and future research would benefit from more prospective observational cohort studies with appropriate inclusion criteria and larger sample sizes to better understand the QoL and HS in this population. Layman’s Abstract: Few studies have deeply investigated the effect of aging on Quality of Life, perceived Health Status and satisfaction with the prosthesis on older trans-tibial amputees. This review focuses on these aspects, which can guide professionals on how to improve prosthetic and rehabilitative intervention in this particular amputees’ population. The results of this review indicate that the Quality of Life and Health Status seem to be influenced by adequate rehabilitation, pain management and an accurate choice of appropriate prosthetic components.

Background: The symptoms of sciatic herpes zoster are sometimes difficult to distinguish from sciatica caused by lumbar disc herniation. We describe a case of suspected lumbar disc herniation with sciatic herpes zoster to reduce the rate of misdiagnosis.Case Report: A 55-year old man, male, developed low back pain after carrying heavy items 20 years ago. Characteristics of symptoms: 1. Symptoms were aggravated in the upright lumbar forward flexion position; 2. The VAS (leg) score was 8–9 points and the VSA (lumbar) score was 0 point; 3. It can be relieved when rested in the supine position; 4. It came on intermittently with radiation pain in the right lower limb. There were several attacks every year. One month ago, there was radiating pain in the right lower limb. The pain was from the back of the right hip, behind the thigh, in lateral crural region, to the back of the foot. And Symptoms worsened for 10 days. The VAS score was 8 points. Pain could not be relieved by rest or changing posture. There was no back pain, no lower limbs, weak walking, no claudication and other symptoms. Analgesics and neurotrophic drugs are ineffective. After the application of antiviral drugs, the radiation pain in the right lower extremity was significantly relieved.Conclusion: We describe this case in detail and discuss how to make an authentic diagnosis, with a concomitant literature review.

Abstract To establish an exercise in open muscular chain rehabilitation (OMC), it is necessary to choose the type of kinematic chain of the mechanical / biomechanical system that constitutes the lower limbs in interaction with the robotic device. Indeed, it’s accepted in biomechanics that a rehabilitation exercise in OMC of the lower limb is performed with a fixed hip and a free foot. Based on these findings, a kinematic structure of a new machine, named Reeduc-Knee, is proposed, and a mechanical design is carried out. The contribution of this work is not limited to the mechanical design of the Reeduc-Knee system. Indeed, to define the minimum parameterizing defining the configuration of the device relative to an absolute reference, a geometric and kinematic study is presented.

Alexithymia is a construct defined as the inability to differentiate between emotional experiences and bodily sensations. According to existing knowledge, alexithymia may have a major effect on the process of treatment and the outcome of the hemodialysis disease. The objective of this literature review was to determine the significance that alexithymia has for compliance and variables of clinical and mental health in the population of hemodialysis patients. For the above purpose, bibliographic databases “MEDLINE” and “Web of Science” were searched. The matrix method was used in analysis of articles. Searching both databases resulted in 248 articles. After applying exclusion and inclusion criteria, we included results of 13 articles in the literature review. The results of the search are findings regarding the prevalence and correlation of alexithymia with variables of clinical and mental health in hemodialysis patients. Alexithymia is significantly more common in the population of hemodialysis patients, and it has a negative effect on their mental and somatic health. Alexithymia levels in hemodialysis patients are more pronounced in cases where there is a greater number of comorbidities. Alexithymia is the predictor of high mortality rate in the population of hemodialysis patients, independent of other comorbidities.

The purpose of this study was to investigate the effects of how limb dominance and joint immobilization alter markers of physical demand and muscle activation during ambulation with axillary crutches. In a crossover, counterbalanced study design, physically active females completed ambulation trials with three conditions: (1) bipedal walking (BW), (2) axillary crutch ambulation with their dominant limb (DOM), and (3) axillary crutch ambulation with their nondominant limb (NDOM). During the axillary crutch ambulation conditions, the non-weight-bearing knee joint was immobilized at a 30-degree flexion angle with a postoperative knee stabilizer. For each trial/condition, participants ambulated at 0.6, 0.8, and 1.0 mph for five minutes at each speed. Heart rate (HR) and rate of perceived exertion (RPE) were monitored throughout. Surface electromyography (sEMG) was used to record muscle activation of the medial gastrocnemius (MG), soleus (SOL), and tibialis anterior (TA) unilaterally on the weight-bearing limb. Biceps brachii (BB) and triceps brachii (TB) sEMG were measured bilaterally. sEMG signals for each immobilization condition were normalized to corresponding values for BW.HR (p < 0.001) and RPE (p < 0.001) were significantly higher for both the DOM and NDOM conditions compared to BW but no differences existed between the DOM and NDOM conditions (p > 0.05). No differences in lower limb muscle activation were noted for any muscles between the DOM and NDOM conditions (p > 0.05). Regardless of condition, BB activation ipsilateral to the ambulating limb was significantly lower during 0.6 mph (p = 0.005) and 0.8 mph (p = 0.016) compared to the same speeds for BB on the contralateral side. Contralateral TB activation was significantly higher during 0.6 mph compared to 0.8 mph (p = 0.009) and 1.0 mph (p = 0.029) irrespective of condition. In conclusion, limb dominance appears to not alter lower limb muscle activation and walking intensity while using axillary crutches. However, upper limb muscle activation was asymmetrical during axillary crutch use and largely dependent on speed. These results suggest that functional asymmetry may exist in upper limbs but not lower limbs during assistive device supported ambulation.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Exercise prescription is one of the main components of phase III Cardiac Rehabilitation (CR) programs due to its documented prognostic benefits. It has been well established that, when added to aerobic training, resistance training (RT) leads to greater improvements in peripheral muscle strength and muscle mass in patients with cardiovascular disease (CVD). With COVID-19, most centre-based CR programs had to be suspended and CR patients had to readjust their RT program to a home-based model where weight training was more difficult to perform. How COVID-19 Era impacted lean mass and muscle strength in trained CVD patients who were attending long-term CR programs has yet to be discussed. Purpose To assess upper and lower limb muscle strength and lean mass in CVD patients who had their centre-based CR program suspended due to COVID-19 and compare it with previous assessments. Methods 87 CVD patients (mean age 62.9 ± 9.1, 82.8% male), before COVID-19, were attending a phase III centre-based CR program 3x/week and were evaluated annually. After 7 months of suspension, 57.5% (n = 50) patients returned to the face-to-face CR program. Despite all constraints caused by COVID-19, body composition and muscle strength of 35 participants (mean age 64.7 ± 7.9, 88.6% male) were assessed. We compared this assessment with previous years and established three assessment time points: M1) one year before COVID-19 (2018); M2) last assessment before COVID-19 (2019); M3) the assessment 7 months after CR program suspension (last trimester of 2020). Upper limbs strength was measured using a JAMAR dynamometer, 30 second chair stand test (number of repetitions – reps) was used to measure lower limbs strength and dual energy x-ray absorptiometry was used to measure upper and lower limbs lean mass. Repeated measures ANOVA were used. Results Intention to treat analysis showed that upper and lower limbs lean mass did not change from M1 to M2 but decreased significantly from M2 to M3 (arms lean mass in M2: 5.68 ± 1.00kg vs M3: 5.52 ± 1.06kg, p = 0.004; legs lean mass in M2: 17.40 ± 2.46kg vs M3: 16.77 ± 2.61kg, p = 0.040). Lower limb strength also decreased significantly from M2 to M3 (M2: 23.31 ± 5.76 reps vs M3: 21.11 ± 5.31 reps, p = 0.014) after remaining stable in the year prior to COVID-19. Upper limb strength improved significantly from M1 to M2 (M1: 39.00 ± 8.64kg vs M2: 40.53 ± 8.77kg, p = 0.034) but did not change significantly from M2 to M3 (M2 vs M3: 41.29 ± 9.13kg, p = 0.517). Conclusion After CR centre-based suspension due to COVID-19, we observed a decrease in upper and lower limbs lean mass and lower limb strength in previously trained CVD patients. These results should emphasize the need to promote all efforts to maintain physical activity and RT through alternative effective home-based CR programs when face-to-face models are not available or possible to be implemented.

Abstract Background Managing thrombosis in rare sites is challenging. Existing studies and guidelines provide detailed explanations on how to overcome lower-limb thromboses and pulmonary embolisms, but few studies have examined thrombosis in rare sites. Lack of data makes clinical practice heterogeneous. Recommendations for diagnosing, treating, and following-up internal jugular vein thrombosis are not clearly defined and mostly based on adapted guidelines for lower-limb thrombosis. Case presentation A 52-year-old Caucasian woman came to the Emergency Department with chest, neck, and left arm pain. Computed tomography imagery showed a left internal jugular vein thrombosis. An extensive workup revealed a heterozygous factor V Leiden gene. Therapy was initiated with intravenous unfractionated heparin, then switched to oral acenocoumarol, which resolved the symptoms. Based on this case presentation and a literature review, we summarize the causes, treatment options, and prognosis of unprovoked internal jugular vein thrombosis. Conclusions Managing internal jugular vein thrombosis lacks scientific data from large randomized clinical trials, partly because such thromboses are rare. Our literature review suggested that clinical treatments for internal jugular vein thrombosis often followed recommendations for treating lower-limb thrombosis. Future specific studies are required to guide clinicians on the modalities of diagnosis, screening for thrombophilia or oncologic disease, treatment duration, and follow-up.
