CONTEXT AND OBJECTIVE: Maintainance of postural balance requires detection of body movements, integration of sensory information in the central nervous system and an appropriate motor response. The purpose of this study was to evaluate whether lower-limb dominance has an influence on postural balance. DESIGN AND SETTING: This was a cross-sectional study conducted at Faculdade de Medicina da Universidade de São Paulo (FMUSP) and at Hospital do Coração (HCor). METHODS: Forty healthy sedentary males aged 20 to 40 years, without any injuries, were evaluated. A single-foot balance test was carried out using the Biodex Balance System equipment, comparing the dominant leg with the nondominant leg of the same individual. The instability protocols used were level 8 (more stable) and level 2 (less stable), and three instability indices were calculated: anteroposterior, mediolateral and general. RESULTS: The volunteers' mean age was 26 ± 5 years (range: 20-38), mean weight 72.3 ± 11 kg (range: 46-107) and mean height 176 ± 6 cm (range: 169-186). Thirty-four of them (85%) presented right-leg dominance (defined according to which leg they used for kicking) and six (15%) had left-leg dominance. There were no significant differences between the dominant and nondominant legs at the two levels of stability (eight and two), for any of the instability indices (general, anteroposterior and mediolateral). CONCLUSION: The lower-limb dominance did not influence single-foot balance among sedentary males.

Background: Sarcopenia is the involuntary loss of muscle mass predicted by aging and is associated with an increased likelihood ofunfavorable results, such as falls, mortality and functional disabilities. Objective: Evaluate balance, gait speed, lower limb strength andfunctionality in sarcopenic and non-sarcopenic elderly. Methods: Cross-sectional study, carried out with 68 subjects aged 60 years orover, residents of the community and possessing an independent gait. The assessment instruments were bioimpedance, balance test,four-meter gait speed test, chair support test and SPPB. Results: The prevalence of sarcopenia in the population of the present studywas 43.3%. In the group of non-sarcopenic subjects, a correlation was found between all the variables evaluated. In the group ofsarcopenic subjects, a correlation was found between lower limbs strength and gait speed. Conclusion: The skeletal muscle mass ofa sarcopenic elderly is related to their lower limb strength and gait speed, but it does not present a significant correlation with balanceand functional performance. Further studies are needed to clarify the behavior of balance, gait speed, lower limb strength and functionalperformance variables when compared to the decrease in muscle mass inherent in aging.

Introduction: Surfing is a discipline that has considerably increased the number of followers who practice this sport. Research has focused on describing the main variables associated with performance, but not the relationships that may exist between them. Objective: To establish the relationship of dynamic postural balance with respect to the anthropometric profile and physical aptitude in surfers. Material and method: This research is an observational and cross-sectional study of a descriptive-correlational type. The sample included 30 surfers (8 women and 22 men). The variables of the anthropometric profile studied were body mass, bipedal height, body mass index (BMI), sum of folds, body composition and somatotype. Furthermore, physical aptitude was assessed by indirect tests. The data of the anthropometric profile and physical aptitude were correlated with the results of the dynamic postural balance test (Y balance test). Results: For the anterior direction of the Y balance test, the variables that were significant were gender, body weight, bipedal height, sum of folds, adipose mass and Sargent’s jump height (R2 = 0.55). The posteromedial direction of the Y balance test yielded a significant model that indicates that gender, sum of folds and adipose mass are the variables that jointly predict dynamic postural balance (R2 = 0.30). For the posterolateral direction, the model indicates that the BMI, sum of folds, adipose mass, mesomorphism, ectomorphism and performance in the sit and reach test are the variables that influence the performance of the Y balance test (R2 = 0.55). Conclusion: Predictive models were established to determine anthropometric and physical condition variables that would be decisive for the performance of a surfer’s postural balance.

Limb Dominance

Context Patellar tendinopathy is common in basketball players, and structural ultrasound abnormalities can be found in symptomatic and asymptomatic tendons. Lower limb dominance may also be a critical load factor, potentially leading to overloading of the patellar tendon. Objective To describe and compare the prevalence by lower limb dominance of patellar tendons with structural and vascular abnormalities and to describe the morphologic measures of tendons without abnormalities among adult male elite basketball players. Design Cross-sectional study. Setting Medical center of a professional basketball team in the Spanish league. Patients or Other Participants A total of 73 adult male elite basketball players (146 patellar tendons; age = 26.8 ± 4.9 years, height = 198.0 ± 0.1 cm, mass = 95.4 ± 11.4 kg). Main Outcome Measure(s) We used ultrasound to screen the patellar tendons for the presence of structural and vascular abnormalities. Tendons were categorized as abnormal if they demonstrated a focal area of hypoechogenicity, thickening, or neovascularization. We also examined the cross-sectional area and thickness of tendons without abnormalities. Prevalence and morphologic measures were compared by limb dominance. Results A total of 35 players (48%) had bilateral abnormalities, whereas 21 (28.7%) had unilateral abnormalities. Among the 91 abnormal tendons, 90 (61.6% of 146 tendons) exhibited a focal area of hypoechogenicity, 59 (40.4% of 146 tendons) exhibited thickening, and 14 (9.6% of 146 tendons) exhibited neovascularization. No group differences were detected between the dominant and nondominant limbs. Among the 55 normal patellar tendons, 34 were bilateral (from 17 players) and 21 were unilateral. Approximately 25% (n = 14) of all 55 normal tendons had a cross-sectional area that was greater than 182.8 mm2 and a thickness greater than 7.2 mm. Among the 34 bilateral normal tendons, no group differences were observed between the dominant and nondominant limbs for either cross-sectional area or thickness. Conclusions The prevalence of abnormal tendons was high among adult male elite basketball players, and bilateral presentations were more frequent. Structural abnormalities were most common.

The majority of people with Multiple Sclerosis (pwMS), report lower limb motor dysfunctions, which may relevantly affect postural control, gait and a wide range of activities of daily living. While it is quite common to observe a different impact of the disease on the two limbs (i.e., one of them is more affected), less clear are the effects of such asymmetry on gait performance. The present retrospective cross-sectional study aimed to characterize the magnitude of interlimb asymmetry in pwMS, particularly as regards the joint kinematics, using parameters derived from angle-angle diagrams. To this end, we analyzed gait patterns of 101 pwMS (55 women, 46 men, mean age 46.3, average Expanded Disability Status Scale (EDSS) score 3.5, range 1–6.5) and 81 unaffected individuals age- and sex-matched who underwent 3D computerized gait analysis carried out using an eight-camera motion capture system. Spatio-temporal parameters and kinematics in the sagittal plane at hip, knee and ankle joints were considered for the analysis. The angular trends of left and right sides were processed to build synchronized angle–angle diagrams (cyclograms) for each joint, and symmetry was assessed by computing several geometrical features such as area, orientation and Trend Symmetry. Based on cyclogram orientation and Trend Symmetry, the results show that pwMS exhibit significantly greater asymmetry in all three joints with respect to unaffected individuals. In particular, orientation values were as follows: 5.1 of pwMS vs. 1.6 of unaffected individuals at hip joint, 7.0 vs. 1.5 at knee and 6.4 vs. 3.0 at ankle (p < 0.001 in all cases), while for Trend Symmetry we obtained at hip 1.7 of pwMS vs. 0.3 of unaffected individuals, 4.2 vs. 0.5 at knee and 8.5 vs. 1.5 at ankle (p < 0.001 in all cases). Moreover, the same parameters were sensitive enough to discriminate individuals of different disability levels. With few exceptions, all the calculated symmetry parameters were found significantly correlated with the main spatio-temporal parameters of gait and the EDSS score. In particular, large correlations were detected between Trend Symmetry and gait speed (with rho values in the range of –0.58 to –0.63 depending on the considered joint, p < 0.001) and between Trend Symmetry and EDSS score (rho = 0.62 to 0.69, p < 0.001). Such results suggest not only that MS is associated with significantly marked interlimb asymmetry during gait but also that such asymmetry worsens as the disease progresses and that it has a relevant impact on gait performances.

Cellulitis is a bacterial infection of the dermis and subcutaneous tissues occupying a large proportion of hospital beds. This study was conducted for analysis of patients with cellulitis according to their demographics and clinical presentation and to examine their comorbidities, complications, and its management. This observational cross-sectional study was conducted in the Department of Surgery at Santosh Medical College and Hospitals involving a total of 60 cases having cellulitis and other soft tissue infections of lower limb. Analysis of their demographic profile, management, and complications was done. Cellulitis is seen commonly in males, 46 (76.6%). The mean age of patients affected by cellulitis in the study was 36.4 ± 1.23 years. The most common site affected is leg involving more people in field jobs. The most common risk factor was trauma in 46.6%, and other factors were diabetes mellitus and smoking, while abscess formation was the most common complication observed in 36.6% of cases. A total of 56.6% cases were managed conservatively, while 43.3% cases required surgical intervention. Mean hospital stay in this study was 5.02 ± 0.23 days. It was concluded that cellulitis is subcutaneous, spreading bacterial infection is more common in males, and its incidence is highest in working age group population. Lower limb is commonly involved. Trauma, smoking, and diabetes are significant risk factors for development of cellulitis. Abscess is the most common complication. About 50% patients with cellulitis can be managed conservatively and the rest require surgical intervention.

Pain Distribution

Design: Cross-sectional study. Background: Osteoarthritis is one of the most common conditions in our society. A growing number of studies suggest the existence of central sensitization (CS) in a subgroup of osteoarthritic patients. One of the criteria included for the classification of CS pain is the expanded distribution of pain. As this criterion is a well-recognized sign of CS, a digital pain drawing (DPD) analysis would be useful to easily identify possible extended areas of pain distribution (PD) in patients with OA. Objective: To study the relationship between the percentage of distribution of pain in the lower limb for both knee and hip, in patients before hip or knee arthroplasty, and the Central Sensitization Inventory Questionnaire. Methods: Twenty women (mean [Formula: see text] years) with diagnosed chronic (over 3 months) knee ([Formula: see text]) and hip ([Formula: see text]) OA participated in the study, with intensity of pain from mild to severe, meaning pain [Formula: see text]/10 using the Numeric Pain Rating Scale (NPRS). The PD was analyzed via software created for this research, called “Pain Distribution Application”. Results: A statistically significant positive correlation between CSI and PD to the lower extremity OA (hip and knee) ([Formula: see text], [Formula: see text]) was found. The distribution of pain has a linear correlation with the results in CSI, of patients who tested positive for CS, i.e. with a score of [Formula: see text]. Conclusions: As the distribution of pain on the surface of the body (diffusion) increases, so does the score of people who test positive for CSI. Our results showed that calculating the distribution of pain with our application may have a utility as a CS screening tool. The PD threshold of 10% of the body area is an index for CS for chronic pain lower limb OA patients.

Context: Core stability is important for preventing injury and improving performance. Although various tests for evaluating core stability have been reported to date, information on their relationship and the effect of gender differences is limited. This study aimed to (1) identify correlations among the 3 core stability tests and to examine the validity of each test and (2) identify gender differences in the test relationship and determine whether gender influenced test selection. Design: Cross-sectional study. Methods: Fifty-one healthy volunteers (27 men and 24 women) participated in the study. The participants underwent the following 3 tests: Sahrmann Core Stability Test (SCST), the lumbar spine motor control tests battery (MCBT), and Y Balance Test (YBT). Each parameter was analyzed according to all parameters and gender using the Spearman rank correlation coefficient. Results: Overall, there was a strong positive correlation between SCST and MCBT and moderate positive correlations between SCST and YBT and between MCBT and YBT. Conversely, gender-specific analyses revealed no significant correlations between YBT and SCST and between YBT and MCBT in women, although significantly strong correlations were found among all tests in men. Conclusion: Although these 3 tests evaluated interrelated functions and may be valid as core stability tests, the results should be carefully interpreted when performing YBT in women.
