Midterm outcomes of patellofemoral arthroplasty / Resultados a medio plazo de la artroplastia femoropatelar

Background: The purpose of this study is the evaluation of the patellofemoral arthroplasty (PFA) survival and clinical and radiological outcomes in our institution. Methods: A retrospective evaluation of our institution patellofemoral arthroplasty cases from 2006 to 2018 was performed; the n sample after applying exclusion and inclusion criteria was 21. All patients excepting one were female with a median age of 63 (20–78). A Kaplan–Meier survival analysis at ten years was calculated. Informed consent was obtained from all patients prior being included in the study. Results: The total revision rate was 6 out of 21 patients (28.57%). The progression of the osteoarthritis in the tibiofemoral compartment was the main cause (50% of revision surgeries). The degree of satisfaction with the PFA was high, with a mean Kujala score of 70.09 and a mean OKS of 35.45 points. The VAS score improved significantly (p<0.001) from a preoperative mean of 8.07 to a postoperative mean of 3.45, with an average improvement of 5 (2–8). Survival at 10 years, with revision for any reason as the endpoint, was 73.5%. A significant positive correlation between BMI and the WOMAC pain (r=0.72, p<0.01) and between BMI and the post-operative VAS (r=0.67, p<0.01) was observed. Conclusions: The results of the case series under consideration suggest that PFA could be a possibility in the joint preservation surgery on the isolated patellofemoral osteoarthritis. BMI >30 seems to be a negative predictor factor in relationship with the postoperative satisfaction, increasing the pain proportionally to this index and requiring more replacement surgery than patients with BMI <30. Meanwhile the radiologic parameters of the implant are not correlated with the clinical or functional outcomes.(AU)

Antecedentes: El propósito de este estudio es la evaluación de la supervivencia de la prótesis femoropatelar y los resultados clínicos y radiológicos en nuestro centro. Métodos: En el presente estudio se realiza una evaluación retrospectiva de los casos de prótesis femoropatelar en nuestro centro entre los años 2006 y 2018. El tamaño muestral, tras aplicar los criterios de inclusión y de exclusión, fue de 21 pacientes. Todos los pacientes excepto uno fueron mujeres, con una media de edad de 63 años (rango 20-78). Se calculó una gráfica de Kaplan-Meier de supervivencia en los primeros 10 años. El consentimiento informado de todos los pacientes fue obtenido previamente a la inclusión en este estudio. Resultados: La tasa de recambio a prótesis total fue 6 de 21 pacientes (28,57%). La progresión de la osteoartrosis en el compartimento tibiofemoral fue la causa principal (50% de las cirugías de revisión). El grado de satisfacción con la PFA fue alto, con una media en la escala de Kujala de 70,09 y una media de OKS de 35,45 puntos. La EVA mejoró significativamente (p<0,001), de una media preoperatoria de 8,07 a una media postoperatoria de 3,45, siendo la media de mejoría de 5 puntos (2 a 8 puntos). La supervivencia a los 10 años, con rescate de la prótesis debido a cualquier causa, fue del 73,5%. Se observó una correlación positiva ente el IMC y la escala WOMAC (r=0,72, p>0,01) y entre el IMC y la EVA postoperatoria (r=0,67 y p<0,01). Conclusiones: Los resultados de esta serie de casos mostraron que la prótesis femoropatelar puede ser una alternativa de tratamiento como cirugía de preservación de la osteoartritis femoropatelar aislada. El IMC>30 parece ser un factor predictor negativo en relación con la satisfacción postoperatoria, incrementando el dolor con una correlación positiva con este índice y requiriendo mayor cirugía de reemplazo que los pacientes con IMC<30.

Evaluation of rectus abdominis muscle strength and width of hernia defect in patients undergoing incisional hernia surgery.

BACKGROUND: The aim of this study was to analyze the strength status of the rectus abdominis muscle in patients with incisional hernia and the relationship between the width of the hernia defect and the strength of the rectus abdominis muscle. METHODS: This is a observational cohort study of patients with medial line incisional hernia (July-October 2022), classified as W2 according to the European Hernia Society (EHS). The data collected were demographic and clinical characteristics related to hernia, and measure of the rectus abdominis muscle strength using an isokinetic dynamometer and a strain gauge. We analyzed the relationship between hernia width and rectus abdominis muscle strength with correlation tests to adjustment by age, sex, BMI, and body composition. RESULTS: A total of 40 patients (64% female) with a mean age of 57.62 years (SD 11) were enrolled in the study. The mean BMI was 29.18 (SD 5.06), with a mean percentage of fat mass of 37.8% (SD 8.47) and a mean percentage of muscle mass of 60.33% (SD 6.43). The maximum width of the hernia defect was 6.59 cm (SD 1.54). In the male group, the mean bending force moment (ISOK_PT) was 94.01 Nw m (SD 34.58), bending force moment relative to body weight (ISOK_PT_Weight) was 103.32 Nw m (SD 37.48), and peak force (PK_90) was 184.71 N (SD 47.01). In the female group, these values were 58.11 Nw m (SD 29.41), 66.48 Nw m (SD 32.44), and 152.50 N (SD 48.49), respectively. Statistically significant differences were observed in the relationship between the data obtained with the isokinetic dynamometer and sex (p = 0.002), as well as between the data obtained with the isokinetic dynamometer and age (p = 0.006). Patients in the 90th percentile (P90) of rectus abdominis muscle strength also had smaller hernia defect widths (p = 0.048). CONCLUSIONS: In this study, age and sex were identified as the most statistically significant predictor variables for rectus abdominis muscle strength. The width of the hernia defect exhibited a trend towards statistical significance.

Effects of non-supervised exercise interventions on bone mineral density in adult women: a systematic review and meta­analysis.

Osteoporosis is a major health issue worldwide. This study analyzes the effects of non-supervised osteoporosis prevention programs on bone mineral density. Non-supervised exercise increases femoral neck and lumbar spine bone mineral density in adult women. Thus, it might be effective for preventing or treating osteoporosis or osteopenia in this population. INTRODUCTION: Osteoporosis is a major health issue worldwide. Social distancing measures due to COVID-19 have hindered the chances to take part in supervised osteoporosis prevention exercise programs. The purpose of the present study is to systematically review and meta-analyze the effects of non-supervised osteoporosis prevention exercise programs on bone mineral density (BMD) in adult women. METHODS: A comprehensive search of electronic databases (n = 7) was conducted including (a) prospective randomized controlled trials (RCTs) comparing at least one exercise group vs. a control group with sedentary lifestyle or sham exercises; (b) baseline and follow-up BMD values, or BMD changes from baseline, at any skeletal site; (c) women over 30 years old; and (d) non-supervised exercise programs only. Subgroup analyses were performed for menopausal status, intervention duration, type of exercise, and osteopenia/osteoporosis status. RESULTS: Ten studies were included (n = 668). Random effect analyses showed that unsupervised exercise had beneficial effects on lumbar spine (LS) BMD with standardized mean difference (SMD) = 0.40 (95% confidence interval (CI): 0.03-0.77), and femoral neck (FN) BMD with SMD = 0.51 (95% CI: 0.16-0.85). Unsupervised exercise increased LS (SMD = 0.73 (95% CI: 0.13-1.33)) and FN BMD (SMD = 0.85 (95% CI: 0.33-1.37)) in women with osteopenia/osteoporosis, but not in healthy counterparts. CONCLUSION: Non-supervised exercise improves FN and LS BMD in adult women. Beneficial effects of exercise on FN and LS BMD might be more pronounced in those with poor bone health compared with healthy counterparts. More RCTs prescribing non-supervised, osteogenic exercise are required in this population. It is necessary to investigate the efficacy of remote/assistive technologies for delivering and monitoring non-supervised exercise interventions.

Influencia de la localización del acelerómetro para cuantificar la actividad física en programas para la prevención de osteoporosis / Influence of accelerometer location to quantify physical activity in osteoporosis prevention programs / Influência da localização do acelerômetro na quantificação da atividade física em programas de prevenção da osteoporose

OBJETIVO: La actividad física tiene efectos positivos sobre la salud ósea. Para desarrollar programas de prevención de la osteoporosis basados en actividad física, la intensidad de la misma debe cuantificarse con precisión con el fin de garantizar su efectividad así como la integridad esquelética del individuo. El objetivo ha sido evaluar la influencia de la localización del acelerómetro para cuantificar la intensidad de la actividad física en programas para la prevención de osteoporosis. MÉTODO: Dieciocho mujeres premenopáusicas completaron un protocolo de ejercicio compuesto por cinco saltos con contramovimiento y cuatro series en tapiz rodante a distintas velocidades. Las participantes portaron acelerómetros situados en muñeca y cadera, y se compararon las medidas de aceleración registradas en ambas localizaciones. Se realizaron tres tipos de análisis: 1) Asociación entre mediciones de ambas localizaciones. 2) Nivel de similitud en las estimaciones grupales. 3) Evaluación del sesgo de medición. RESULTADOS: Baja correlación entre medidas de aceleración registradas en muñeca y cadera en todas las pruebas de protocolo (r= 0.046-0.469, p < 0.05). Las diferencias entre las estimaciones grupales y el sesgo de medición aumentan a medida que se incrementa la velocidad en el tapiz rodante. CONCLUSIONES: La aceleración medida en la muñeca podría sobreestimar la aceleración realmente producida en la cadera. Este efecto debe tenerse en cuenta a la hora de cuantificar la carga en programas de actividad física para la prevención de la osteoporosis

OBJECTIVE: Physical activity has positive effects on bone health. In order to develop osteoporosis prevention programs based on physical activity, exercise intensity must be precisely quantified in order to guarantee its effectiveness as well as to ensure skeletal integrity. The objective has been assessing the influence of the accelerometer location to quantify the intensity of physical activity in osteoporosis prevention programs. METHOD: Eighteen premenopausal women completed an exercise protocol consisting of five countermovement jumps followed by four treadmill bouts at different speeds. Participants carried accelerometers located on the wrist and hip, and the acceleration measures recorded at both locations were compared. Three types of analysis were analyzed: 1) Association between measurements from both locations. 2) Level of similarity in group estimates. 3) Evaluation of measurement bias. RESULTS: Low correlation between peak acceleration measured at hip and wrist in all protocol tests (r= 0.046-0.469, p < 0.05). Differences in group estimates and measurement bias between the records of both locations increase as the treadmill speed does. CONCLUSIONS: Acceleration measured in the wrist could overestimate the acceleration produced in the hip. This effect must be taken into account when quantifying mechanical loads in physical activity programs for the prevention of osteoporosis

MÉTODO: Dezoito mulheres na pré-menopausa completaram um protocolo de exercícios composto por cinco saltos com contramovimento e quatro séries em esteira em diferentes velocidades. Os participantes carregaram acelerômetros localizados no punho e no quadril, e as medidas de aceleração registradas nos dois locais foram comparadas. Foram realizados três tipos de análise: 1) Associação entre as medidas dos dois locais. 2) Nível de similaridade nas estimativas de grupo. 3) Avaliação do viés de medição. RESULTADOS: Baixa correlação entre as medidas de aceleração registradas no punho e no quadril em todos os testes de protocolo (r = 0.046-0.469, p <0.05). As diferenças entre as estimativas de grupo e o viés de medição aumentam à medida que a velocidade na esteira aumenta. CONCLUSÕES: A aceleração medida no pulso pode superestimar a aceleração realmente produzida no quadril. Esse efeito deve ser levado em consideração na quantificação da carga de programas de atividade física para a prevenção da osteoporose

'Exercise to me is a scary word': perceptions of fatigue, sleep dysfunction, and exercise in people with fibromyalgia syndrome-a focus group study.

Fibromyalgia syndrome (FMS) is a common and complex chronic pain condition. Exercise is recommended in the management of the FMS; however, people with FMS often find exercise exacerbates their condition and causes overwhelming fatigue. The objective of this study was to explore the perceptions of fatigue and sleep dysfunction, and exercise in people with FMS. Three, 60-90 min focus groups were conducted with people with FMS (n = 14). Participants were recruited from patient support groups who had experienced therapeutic exercise in the management of their condition. Focus groups were video and audio recorded and transcriptions analysed for thematic content by three independent evaluators. Fatigue, sleep dysfunction, and pain were universally reported by participants. The over-arching theme to emerge was a lack of understanding of the condition by others. A huge sense of loss was a major sub-theme and participants felt that they had fundamentally changed since the onset of FMS. Participants reported that they were unable to carry out their normal activities, including physical activity and exercise. The invisibility of FMS was associated with the lack of understanding by others, the sense of loss, and the impact of FMS. People with FMS perceive that there is a lack of understanding of the condition among health care professionals and the wider society. Those with FMS expressed a profound sense of loss of their former 'self'; part of this loss was the ability to engage in normal physical activity and exercise.

Effects of eccentric overload bout on change of direction and performance in soccer players.

The aims of this study were to analyse the effects of eccentric overload training (EOT) on kinetic parameters during change of direction (COD) and performance related to sprinting and jumping abilities. 20 male soccer players performed 2 different protocols: 1) 5-min cycling warm-up and 2) 5-min cycling warm-up+YoYo half-squat exercise. The outcome measured included vertical ground reaction force (vGRF) and propulsive force (PvGRF), time to vGRF (T_vGRF) and propulsive force (T_PvGRF), contact time (CT), eccentric (ECC_IMP), concentric (CONC_IMP) and total (TOT_IMP) impulses and moments (Mx, My and Mz) during 2 COD tasks. Additionally, subjects performed a counter-movement jump (CMJ) and 20 m sprint tests. Results showed a substantial better improvement (likely to almost certainly) in vGRF (ES: 0.84), vAGRF (ES: 0.72), CT (ES: 0.48), My (ES: 0.35), Mz (ES: 0.44) and ECC_IMP (ES: 0.45) during crossover cutting maneuver, whereas during side-step cutting maneuver Time_ECC (ES: 0.68), CT (ES: 0.64), vGRF (ES: 0.48) and My (ES: 0.47) were substantially enhanced (likely). Furthermore, substantial better performance was found in CMJ (ES: 0.47; very likely) and 20 m (ES: 0.20; possibly). In conclusion, EOT produced a better muscle activation during 2 different COD tasks and greater sprinting and jumping performance.

Cardiac autonomic response during recovery from a maximal exercise using whole body vibration.

OBJECTIVE: To examine the effect of passive whole-body vibration (WBV) on heart rate (HR) variability (HRV) during the recovery from intense exercise. DESIGN: Randomized, counterbalanced, crossover design SETTING: Laboratory. INTERVENTIONS: Twenty-three healthy male performed a bicycle exercise test to exhaustion followed by an active recovery period using WBV (25Hz and peak to peak displacement of 4mm) or passive recovery period (noWBV; 0Hz-0mm) on two separate days in random order. The recovery protocol consisted of six 1-min sets separated by 1-min inter-set rest periods in the seated position with the feet on the vibration platform. ECG recordings were made at baseline and during recovery at min 2, 4, 6, 8, 10 and 12 in both conditions. Frequency-domain measures of HRV were determined via power spectral analysis using fast-Fourier transform. Low frequency (LF; 0.04-0.15Hz) and high frequency bandwidths (HF; 0.15-0.4Hz) were determined. RESULTS: HR was increased in both groups (P<0.01) throughout the recovery. At min 2, HR was lower (P=0.05) after WVB compared to the noWBV trial. At min 3, the increase (P<0.05) in total power after WBV was significantly different (P<0.01) compared to noWBV. Normalized (nu) LF and LF/HF were increased (P<0.01), whereas HF nu was reduced (P<0.001) in both conditions without a significant group-by-time interaction (P=0.08). CONCLUSION: Passive WBV reduces HR and increases total power during the early recovery of intense exercise, despite no effect on power spectral components of HRV.

Incidencia del ejercicio físico y el entrenamiento vibratorio sobre la amplitud de movimiento de mujeres con fibromialgia / Influence of physical exercise and whole body vibration on flexibility in women with fibromyalgia

Objetivo. En la presente investigación hemos planteado como objetivos principales, por un lado, valorar el efecto del ejercicio físico y el entrenamiento vibratorio sobre la amplitud de movimiento en mujeres con fibromialgia (FM) y, por otro, determinar si existe alguna relación entre dicha variable y el dolor y la rigidez. Método. La muestra estuvo constituida por un total de cuarenta y seis mujeres (edad: 58,2 ± 8,5 años; peso: 72,1 ± 9,6 kg; altura: 156,9 ± 6,1 cm) diagnosticadas con FM. Los participantes fueron divididos aleatoriamente en tres grupos: ejercicio físico y entrenamiento vibratorio (WBV + EJ; n = 15); ejercicio físico sin vibraciones (EJ; n = 15) y un grupo control (GC; n = 16). Los grupos WBV + EJ y EJ realizaron dos sesiones semanales de ejercicio físico durante 8 semanas. Además, los integrantes de WBV + EJ realizaron 3 sesiones semanales de entrenamiento vibratorio (30 Hz, 4 mm). Las pruebas de evaluación incluyeron el test de sit and reach (variable principal), la valoración del número de tender points (TP) y una escala analógica visual (VAS) para determinar la rigidez. Resultados. Los resultados derivados del análisis intra e intergrupo no mostraron diferencias significativas en la rigidez o el número de TP, si bien, la prueba de sit and reach mostró una mejora estadísticamente significativa en WBV + EJ (58%; p < 0,05). El análisis correlacional mostró una relación inversa (r = -0,55; p < 0,05) entre el sit and reach y el número de TP. Conclusión. Como conclusión, podemos indicar que los datos obtenidos en la presente investigación han mostrado los efectos significativos del entrenamiento vibratorio sobre la amplitud de movimiento en mujeres con FM, aunque el número de TP o la rigidez no se vieron afectados en ningún caso(AU)

Objective. The main aim of this investigation was twofold: first to evaluate the effects of exercise and whole body vibration training on flexibility in women with fibromyalgia (FM) and determine whether these improvements are related to symptom severity (stiffness and bodily pain). Method. Forty-six women (mean ± sd, age: 58.2 ± 8.5 years; weight: 72.1 ± 9.6 kg; height: 156.9 ± 6.1 cm) with FM were randomized into one of three groups: exercise and whole body vibration (WBV) training group (WBV + EX; n = 15), exercise training group (EX), and usual-care control group (CG). WBV + EX and EX groups carried out two sessions per week of exercise training for 8 weeks. In addition, WBV + EX group performed 3 vibration-training (30 Hz, 4 mm) sessions per week. Outcome assessed included sit and reach test (primary outcome), tender points (TP) evaluation, and a visual analog scale (VAS) was used to determine the stiffness level. Results. Results showed no statistical intra and intergroup differences in stiffness or the number of TP. However, a significant increment in the sit and reach performance was observed in WBV + EX (58%; p < 0.05). Moreover, correlation analysis showed an inverse and significant relationship (r = -0.55; p < 0.05) between sit and reach and number of TP in WBV+EX group. Conclusion. In conclusion, exercise and WBV seems to be effective on flexibility in women with FM. However, the number of TP and stiffness was not modified after the intervention(AU)

The relationship between nutritional status, functional capacity, and health-related quality of life in older adults with type 2 diabetes: a pilot explanatory study.

OBJECTIVE: To explore the relationship between nutritional status, functional capacity and health-related quality of life (HRQoL) in older adults with type 2 diabetes (T2DM). DESIGN: Cross-sectional study. SETTING AND PARTICIPANTS: Forty two non-insulin dependent older adults from a primary care center in Seville, Spain. MEASUREMENTS: Function was assessed with a battery of standardized physical fitness tests. Nutritional status was assessed using the Mini Nutritional Assessment (MNA) and the European Quality of Life Questionnaire (EQ-5D-3L) was used to assess HRQoL. RESULTS: There was an association between MNA-nutritional status and lower body strength as assessed by the chair sit-stand test (rho= .451; p= .037) and between MNA-nutritional status and EQ-5D-3L-HRQoL (EQ-5D-3Lutility, rho= .553; p<.001 and EQ-5D-3LVAS rho= .402; p<.001). An MNA item by item correlation analysis with HRQoL and lower limb strength demonstrated that HRQoL appears to be related to functional capacity (principally lower body strength, motor agility and cardiorespiratory fitness) among participants. These results were maintained when correlations were adjusted for co-morbidity. CONCLUSION: Our results demonstrated that nutritional status is moderately associated with HRQoL and lower limb strength in patients with T2DM. Our data suggest that more emphasis should be placed on interventions to encourage a correct diet and stress the needed to improve lower body strength to reinforce better mobility in T2DM population.

Revisión sobre la lesión de la musculatura isquiotibial en el deporte: factores de riesgo y estrategias para su prevención / Review on the hamstring muscle injury in sport: risk factors and prevention strategies

La lesión aguda de la musculatura isquiotibial es una de las más frecuentes en el ámbito deportivo, presentando una alta incidencia e, incluso, una elevada tasa de recurrencia. Ambos fenómenos se han relacionado a menudo con la ineficacia de las estrategias utilizadas para prevenir la aparición de esta lesión, ya que éstas no tienen en consideración, en muchas de las ocasiones, el carácter multifacético de la lesión. Además, la evidencia científica sobre los factores de riesgo asociados a la lesión isquiotibial es limitada aún, lo que dificulta el desarrollo de estrategias de prevención apropiadas. En base a lo expuesto, los objetivos de esta revisión son: analizar los factores de riesgo asociados a esta lesión y, de acuerdo a estos, describir las estrategias utilizadas para prevenir dichas lesiones(AU)

Acute hamstrings injury is one of the most common in sport, presenting a high incidence and even a high recurrence rate. Both are often associated with the ineffectiveness of the strategies used to prevent the occurrence of this injury, because they do not take into cosideration, in many instances, the multifaceted nature of the injury. In addition, scientific evidence about the risk factors associated with hamstring injury is still low, limiting the development of appropriate prevention strategies. Based on the above, the aims of this review are: analyze the risk factors associated with this injury and, according to them, describe the strategies used to prevent injuries(AU)

The effect of 6-week exercise programme and whole body vibration on strength and quality of life in women with fibromyalgia: a randomised study.

OBJECTIVES: The aim of this study was to investigate the effectiveness of a 6-week traditional exercise programme with supplementary whole-body vibration (WBV) in improving strength and health status in women with fibromyalgia (FM). METHODS: Thirty postmenopausal women with FM (mean (SD) age: 59 (7.90) years) were randomised into one of two groups, one intervention group (GEV n=15), which combined exercise training (two days a week) with three days of WBV (3 sets of 45 s at 20 Hz-3 mm and four sets of unilateral static squats at 20 Hz-2 mm) and another control group (n=15), that performed the same physical activity programme but without vibration training (GEnV). The Fibromyalgia Impact Questionnaire (FIQ) and the global score of the SF-36 were used to assess functional capacity and quality of life. Two additional tests were employed to assess muscle strength. Baseline data and pre-test and post-test data were collected before and after the six-week intervention period. RESULTS: Significant improvements in all outcomes measured were found from baseline in both groups. A 5% improvement from baseline in total FIQ score was observed in the exercise groups (p≤0.05), and was accompanied by reductions in SF36 scores of 9.8% (p<0.001) and 7.9% (p<0.001) in the GEV and GEnV group, respectively. Improvements were also observed in muscle strength in both groups but greater in the GEV group. CONCLUSIONS: The results suggest that women with FMS can gain additional health benefits by engaging in a 6-week traditional exercise programme with supplementary WBV.

Using cardiovascular parameters and symptom severity to prescribe physical activity in women with fibromyalgia.

OBJECTIVES: This study has two main aims, firstly to define subgroups of women affected by fibromyalgia syndrome (FMS) based on symptoms and secondly to determine cardiovascular parameters in treadmill exercises in order to prescribe physical activity. METHODS: Thirty-two women (age= 53.26+/-6.61 yr) were assigned to two different groups based on their functional capacity and symptoms as measured by the Fibromyalgia Impact Questionnaire and pain. Subjects were submitted twice to a maximum treadmill incremental test until participants achieved volitional exhaustion (VO2max). Expired respiratory gases, ventilator parameters and heart rate (HR) were measured continuously through exercise, and rate perceived exertion (RPE) was assessed once a minute during the test. RESULTS: Peak VO2 values for the moderately affected group (Group 1) were significantly different from those of severely affected group (Group 2) (26.2+/-2.1 ml x kg(-1) x min(-1) (Group 1) and 22.1+/-2.5 ml x kg(-1) x min(-1) (Group 2)). Additionally taking into account VO2 at ventilatory threshold (VO2VT), significant differences between groups were found in both tests. Some notable differences in all parameters evaluated were also found. CONCLUSION: This study has demonstrated that the aerobic capacity of patients with FMS was different according to how severely affected they were by the condition; therefore, physical activity of the same intensity should not be prescribed for both groups. According to these results, health professionals could prescribe physical activity with confidence to this patient group.
