The Medium-Term Changes in Health-Related Behaviours among Spanish Older People Lifestyles during Covid-19 Lockdown.

OBJECTIVES: The aim was to evaluate general changes and investigate the association between diet quality, physical activity (PA), and sedentary time (ST) during COVID-19 lockdown and the subsequent 7-month changes in health-related behaviours and lifestyles in older people. PARTICIPANTS: 1092 participants (67-97y) from two Spanish cohorts were included. DESIGN: Telephone-based questionaries were used to evaluate health-related behaviours and lifestyle. Multinomial logistic regression analyses with diet quality, PA, and ST during lockdown as predictors for health-related behaviours changes post-lockdown were applied. RESULTS: Diet quality, PA, and ST significantly improved post-lockdown, while physical component score of the SF-12 worsened. Participants with a low diet quality during lockdown had higher worsening of post-lockdown ST and anxiety; whereas those with high diet quality showed less likelihood of remaining abstainers, worsening weight, and improving PA. Lower ST was associated with a higher likelihood of remaining abstainers, and worsening weight and improving social contact; nevertheless, higher ST was linked to improvement in sleep quality. Lower PA was more likely to decrease alcohol consumption, while higher PA showed the opposite. However, PA was more likely to be associated to remain abstainers. CONCLUSIONS: Despite improvements in lifestyle after lockdown, it had health consequences for older people. Particularly, lower ST during lockdown seemed to provide the most medium-term remarkable lifestyle improvements.

How important is current physical fitness for future quality of life? Results from an 8-year longitudinal study on older adults.

INTRODUCTION: A vast amount of research has focused on the effects of physical fitness (PF) on mortality, with little research evaluating the effects of PF on future expected health related quality of life (HRQoL). AIM: To evaluate how current PF influences future HRQoL measured in a prospective 8-year study in older adults. METHODS: A total of 617 (157 males) older adults (>65y) participated in the study. PF was assessed with the EXERNET battery in 2008-2009 (baseline) and 2016-2017 (follow-up). HRQoL was assessed using the EQ-5D-3L questionnaire in both evaluations. PF tertiles were developed from baseline PF variables: FIT (highest PF values), REGULAR and UNFIT (lowest PF values) taking into account age and sex. Follow-up HRQoL values were compared to sex and age-specific expected values. Logistic regressions were performed to test differences between PF tertiles regarding future expected quality of life. Linear regressions were developed to test whether baseline PF could predict future HRQoL scores. RESULTS: The FIT group showed higher probabilities of an improved HRQoL when compared to the UNFIT group. All PF variables seemed to be important at some point of the study except upper extremities flexibility. Aerobic endurance was the variable that showed to be significant for most of the HRQoL predictions. CONCLUSION: PF influences future HRQoL in older adults who accordingly should try to remain fit to maintain an increased age-adjusted HRQoL.

ACTN3 R577X polymorphism related to sarcopenia and physical fitness in active older women.

BACKGROUND: As the population is getting older, physical activity promotion becomes a good strategy to increase quality of life in the elderly; but genetic condition also plays an important role. The purpose of this study was to examine the association of the ACTN3 R577X polymorphism with physical fitness and muscle mass in physically active older women. METHODS: A cross-sectional study was performed with two groups of older women who practiced physical exercise regularly. The first cohort comprised 164 women (age 69.7 ± 3.2 years) and the second cohort 131 women (age 78.5 ± 3.0 years). The main outcome measures were anthropometric measures with assessment of sarcopenia and sarcopenic obesity, self-reported physical activity EXERNET questionnaire (EEPAQ), evaluation of physical fitness (muscle strength and flexibility test), and ACTN3 genotyping. RESULTS: Women above 75 years old with allele R presented a higher risk of experiencing sarcopenia compared to ACTNR XX homozygous women (odds ratio 0.356, 95% confidence interval 0.139-0.915, p = 0.026). Furthermore, statistically significant differences were found in the chair stand test (p = 0.04), as well as in the sit and reach test (p = 0.01), with better results for women below 75 years old with the ACTN3 XX genotype. CONCLUSIONS: Sarcopenia and physical fitness show differences based on the ACTN3 R577X genotype in active older women.

Associations between Physical Fitness, Bone Mass, and Structure in Older People.

The main aim was to analyse the associations between several physical fitness variables and bone parameters in a sample of elderly people. 129 participants (94 females and 35 males, 76.2 ± 5.4 y) from the EXERNET cohort of Zaragoza (Spain) were included in the study. Physical fitness was assessed using the Senior Fitness Test Battery. Peripheral quantitative computed tomography (pQCT) at the tibia and dual-energy X-ray absorptiometry (DXA) at the hip and lumbar spine were used to assess bone and muscle parameters. Partial correlations were used to describe the associations between fitness and bone parameters. A stepwise regression analysis was used to determine the influence of fitness variables on bone parameters. In males, significant correlations were found between lower body strength and agility with bone total mineral density (Tt.BMD) (r = 0.41 and -0.50) and cortical thickness (r = 0.40 and -0.50, respectively) and walking speed with total and cortical density (r = -0.41 and -0.40, respectively), all measured at tibia (all p < 0.05). Regarding DXA, neck areal bone mineral density (aBMD) correlated with flexibility (r = -0.37) and walking speed (r = 0.39) and Ward's triangle with walking speed (r = 0.39). Agility predicted Tt.BMD and cortical thickness (r 2 change = 24.8% and 23.0%), while walking speed predicted cortical bone mineral density (r 2 change = 19.5%) (all p < 0.05). Females showed correlations between balance and total hip aBMD (r = 0.27) and trochanter aBMD (r = 0.25). Balance predicted trochanter (r 2 change = 4.2%) and total hip aBMD (r 2 change = 4.9%) (both p < 0.05). In conclusion, bone mass in elderly males seems to be more influenced by physical fitness than in females, being agility and walking speed the variables showing greater associations. Other variables should be taken into account in females for future research.

Does fitness attenuate the relationship between changes in sitting time and health-related quality of life over time in community-dwelling older adults? Evidence from the EXERNET multicenter longitudinal study.

OBJECTIVE: To assess the relationship between fitness levels and components, sitting time and health-related quality of life (HRQoL), over time among community-dwelling older adults. METHODS: Three different sitting trajectories were calculated: (i) no change; (ii) decrease; and (iii) increase in ST, between baseline and follow-up. Fitness was assessed using the aerobic capacity, upper and lower limb strength, and total fitness. Participants were classified into higher (75th percentile or above) or lower (below 75th percentile) fitness levels, using the fitness tests. HRQoL scores at follow-up were compared to the three different sitting time trajectories within and across both the higher and the lower fitness groups for each of the three fitness indexes. RESULTS: Greater HRQoL scores were observed in those participants that decreased their ST as compared with those increasing their sitting time over time for participants classified in the lower end of their aerobic capacity or total fitness index. No differences were detected in HRQoL scores in people classified in the higher fitness level group for any of the fitness indexes. Participants that increased or did not change their sitting time and who were classified in the higher fitness end of aerobic capacity and total fitness index self-reported higher HRQoL scores when compared with those in the lower fitness end. CONCLUSION: Increased sitting time over time is associated with poorer HRQoL in older adults. Higher fitness levels could help attenuate the negative impact of sitting over time.

Is Sitting Time Related with Physical Fitness in Spanishelderly Population? The EXERNET Multicenter Study.

BACKGROUND: Older adults spend most of their waking hours performing sedentary activities. The influence of these lifestyle patterns on the physical fitness (PF) levels of this population has not yet been sufficiently investigated. OBJECTIVE: The aim of the study was to examine whether sedentary behavior (SB) (h•d-1sitting) is associated with PF, and specifically to analyze whether sitting >4 h•d-1 is associated with higher risk of having lower levels of fitness in seniors. DESIGN: EXERNET multi-center study. PARTICIPANTS AND SETTINGS: A representative sample of 3136 non-institutionalized elderly (aged 72.2±5.3 years), from 6 Regions of Spain were included in the study. MEASUREMENTS: PF was assessed using 8 different tests from the EXERNET battery. Lifestyle patterns were collected using a validated questionnaire. ANOVA was used to compare the groups according to the hours of sitting. Binary logistic regression was used to calculate the association between the SB and low levels of fitness. RESULTS: For both genders, those who spent sitting >4 h•d-1 had lower levels of balance, agility, walking speed and aerobic endurance (p<0.001). Sedentary men also had less strength of lower extremities (p<0.05), whereas, sedentary women were less flexible in the lower extremities (p<0.001). More than 4 h•d-1 sitting was associated, in men, to higher odds for having low strength (lower extremities), agility, flexibility (lower extremities) and aerobic endurance (p<0.05); and in women, to higher risk of low balance, strength (lower and upper extremities), flexibility (lower extremities), agility, walking speed and aerobic endurance (p<0.05). CONCLUSIONS: Seniors that sit >4 h•d-1 have lower levels of fitness and this behavior is related with an increased risk of having low levels of PF in this population.

Non-osteogenic muscle hypertrophy in children with McArdle disease.

INTRODUCTION: McArdle disease is an inborn disorder of muscle glycogen metabolism that produces exercise intolerance, and has been recently associated with low values ​​of lean mass (LM) and bone mineral content (BMC) and density (BMD) in affected adults. Here we aimed to study whether this bone health problem begins in childhood. METHODS: Forty children and adolescents were evaluated: 10 McArdle disease and 30 control children (mean age of both groups, 13 ± 2y). Body composition was evaluated by dual-energy X-ray absorptiometry and creatine kinase (CK) levels were determined in the patients as an estimate of muscle damage. RESULTS: Legs bone mass was significantly lower in patients than in controls (-36% for BMC and -22% for BMD). Moreover, patients had significantly higher LM values in the legs than controls, whereas no difference was found for fat mass. CK levels were positively associated with LM in McArdle patients. A correlation was found between LM and BMD variables in the control group but not in McArdle patients. CONCLUSION: We have identified a 'non-osteogenic muscle hypertrophy' in children with McArdle disease. This phenomenon warrants special attention since low osteogenesis at an early age predicts a high risk for osteoporosis later in life.

Relationship Between Sarcopenia and Frailty in the Toledo Study of Healthy Aging: A Population Based Cross-Sectional Study.

INTRODUCTION: Frailty and sarcopenia are correlates of musculoskeletal aging that represent a state of vulnerability increasing the risk of negative health outcomes. Standardized definitions are lacking for both, and sometimes both concepts are used interchangeably. However, no large study has assessed the coexistence of these 2 entities in a cohort of older community-dwelling people. METHODS: Data were taken from the Toledo Study of Healthy Aging (TSHA), a study of community-dwelling elderly (≥65 years). The study population consists of 1611 participants with frailty and sarcopenia assessments. For sarcopenia, we used 3 criteria: European Working Group on Sarcopenia in Older People (EWGSOP), the Foundation for the National Institutes of Health (FNIH), and the FNIH fitted to the cut-off points of our population [standardized FNIH (sFNIH)]. Frailty was assessed according to the Fried criteria with cut-off points adjusted to our population. We used logistic regression to assess the relationship between sarcopenia and frailty and measures of diagnostic accuracy to evaluate the potential use of sarcopenia as a diagnostic marker for frailty. RESULTS: The mean age of the population was 75.42 years (±5.86). Overall, 72 (4.5%) were frail. In addition, 352 (21.8%), 332 (20.6%), and 453 (28.1%) participants were considered sarcopenic according to the EWGSOP, FNIH, and sFNIH criteria, respectively. The prevalence of frailty among those with sarcopenia was 8.2% (29/352), 15.7% (52/332), and 10.4% (47/453). Moreover, among frail people, the prevalence of sarcopenia was 40.27%, 72.2%, and 65.3% according to the used criteria. Sarcopenia showed a low sensitivity (<10%) but high specificity (>97%) for the diagnosis of frailty, with a low intercorrelation (Cramer V = 0.16, 0.40, and 0.30) between the 3 criteria and frailty. Using multivariate logistic regression, frailty was associated with sarcopenia according to EWGSOP [odds ratio (OR) = 1.67, 95% confidence interval (CI) = 0.95, 2.96], FNIH (OR = 10.61, 95% CI = 5.8, 19.4), and sFNIH (OR = 6.63, 95% CI =3.5, 12.53). CONCLUSION: Frailty and sarcopenia are distinct but related conditions. Sarcopenia is not a useful clinical biomarker of frailty, but its absence might be useful to exclude frailty.

A route to small clusters: a twisted half-hexagram-shaped M4(OH)4 cluster and its capacity for hosting closed-shell metals.

By combining different oxidation states, coordination indices and bridging systems, it has been possible to obtain the structurally novel M4(OH)4 cluster core (M = transition metal) found in the organometallic compound (NBu4)2[PtIVPt(C6Cl5)8(µ2-OH)2(µ3-OH)2] (1). The cluster is formed by two (µ3-OH) and two (µ2-OH) units that bond platinum atoms in different oxidation states. The cluster core geometry can best be described as a half-hexagram. Compound 1 is an excellent precursor for preparing heterometallic clusters since it can host d10 or s2 Lewis-acid metal centers through Pt→M dative bonds, as demonstrated by its reaction with Ag(i) to produce the heterometallic [Ag2PtIVPt(C6Cl5)8(µ2-OH)2(µ3-OH)2] (2), which has four unbridged Pt-Ag bonds.

Sleep disturbance, obesity, physical fitness and quality of life in older women: EXERNET study group.

OBJECTIVES: To investigate the association between physical fitness, obesity, health related quality of life (HRQoL) and sleep disturbance in 463 community-dwelling older Spanish women (66-91 years of age). STUDY DESIGN: Cross-sectional study. METHOD: Sleep disturbance was assessed with the Jenkins Sleep Scale. Active and sedentary behaviors were recorded by standardized questionnaires. HRQoL was assessed with the EuroQoL-5D. Anthropometric measurements were obtained using standardized techniques. Body fat was measured using bioelectrical impedance. Physical fitness was evaluated by a set of eight tests. RESULTS: Sleep disturbance was reported by 45.1% of women, being associated with higher body mass index (p < 0.05) and waist circumference (p < 0.01). Presence of insomnia was inversely associated with physical fitness. Women in the upper tertile of fitness index had 92.0% lower risk of sleep disturbance as compared to the lower tertile (p = 0.08), while women in the highest tertile of upper body strength had 76.4% lower risk of sleep disturbance as compared to the lower tertile (p < 0.05). Women without sleep disturbance showed better HRQoL. CONCLUSION: Sleep disturbance was associated with central obesity, lower physical fitness and reduced HRQoL. Interventions involving weight management and improvement of physical fitness may contribute to better sleep quality in older women.

Variations of Weight of Prostate Gland in Different Age Groups of Bangladeshi Cadaver.

Now a days, benign prostatic hyperplasia and carcinoma of the prostate are the most common disorders in men. A cross sectional descriptive study was conducted in Department of Anatomy, Mymensingh Medical College, Mymensingh to find out the difference in weight of the prostate gland of Bangladeshi people in relation to age. The present study was performed on 67 postmortem human prostate gland collected from the morgue in the Department of Forensic Medicine, Mymensingh Medical College by non random purposive sampling technique. The specimens were collected from Bangladeshi cadaver of age ranging from 10 to 80 years. All the specimens were grouped into three categories - Group A (upto 18 years), Group B (19 to 45 years) and Group C (above 45 years) according to age. Dissection was performed according to standard autopsy techniques. The weight of the prostate gland were measured and recorded. The mean weight of the prostate gland was 10.13gm in Group A, 17.27gm in Group B and 22.50gm in Group C. Variance analysis shows that mean differences of weight of the prostate were highly significant among all age groups. The weight of prostate gland was found to increase with increased age. For statistical analysis, differences between age groups were analyzed by using students unpaired 't' test. The present study will help to increase the information pool on the weight of prostate gland of Bangladeshi people.

The Spanish version of the Three Factor Eating Questionnaire-R21 for children and adolescents (TFEQ-R21C): Psychometric analysis and relationships with body composition and fitness variables.

OBJECTIVE: The main purpose of the present study is to assess the factor structure and reliability of the Spanish version of the 21-item Three Factor Eating Questionnaire (TFEQ-R21C) in children and adolescents and to analyze the relationships between eating behaviors, body composition and cardiovascular fitness. SUBJECTS: A total of 192 children and adolescents took part in this study (89 boys and 103 girls; aged from 8.8 to 16.8years old and with body mass index (BMI) ranging from 13.2 to 41.1kg/m(2)). None of them had either a history of psychological or eating disorders. MEASUREMENTS: Body composition (dual-energy X-ray absorptiometry-DXA), anthropometrics (body mass, height and BMI), cardiovascular fitness (cyclo-ergometer incremental test) and eating behaviors (TFEQ-R21C) were determined in all participants. RESULTS: The confirmatory factor analysis corroborated the same three factors of the original TFEQ-R21: Uncontrolled Eating (UE), Emotional Eating (EE) and Cognitive Restraint (CR). The internal-consistency reliability (Cronbach's alpha coefficient) for the questionnaire was 0.73. Significant differences were found in BMI (F2,189=3.50, p=0.032) and total fat mass (TFM) (F2,189=3.60, p=0.029) between tertiles of the CR scale (children who had the lowest scores, also had lower BMI and fat mass). Cardiovascular fitness (measured by relative VO2 peak) differs depending on the UE and CR scores. The "healthy" group (those who were normal-weight and had also the highest relative VO2 peak) showed a significant lower CR (F3,160=3.07, p=0.030) and higher UE (F3,160=3.86, p=0.011) than the "unhealthy" group (those who were neither normal-weight nor had adequate relative VO2 peak). CONCLUSIONS: According to the psychometric analysis of the questionnaire, the TFEQ-R21C is a valid and useful tool to assess eating behaviors in Spanish child population. Further research is necessary to understand the links between eating behaviors and other health-related behaviors such as physical activity time or cardiovascular fitness.

Demographic history and adaptation account for clock gene diversity in humans.

Circadian clocks give rise to daily oscillations in behavior and physiological functions that often anticipate upcoming environmental changes generated by the Earth rotation. In model organisms a relationship exists between several genes affecting the circadian rhythms and latitude. We investigated the allele distributions at 116 000 single-nucleotide polymorphisms (SNPs) of 25 human clock and clock-related genes from the 1000Genomes Project, and at a reference data set of putatively neutral polymorphisms. The global genetic structure at the clock genes did not differ from that observed at the reference data set. We then tested for evidence of local adaptation searching for FST outliers under both an island and a hierarchical model, and for significant association between allele frequencies and environmental variables by a Bayesian approach. A total of 230 SNPs in 23 genes, or 84 SNPs in 19 genes, depending on the significance thresholds chosen, showed signs of local adaptation, whereas a maximum of 190 SNPs in 23 genes had significant covariance with one or more environmental variables. Only two SNPs from two genes (NPAS2 and AANAT) exhibit both elevated population differentiation and covariance with at least one environmental variable. We then checked whether the SNPs emerging from these analyses fall within a set of candidate SNPs associated with different chronotypes or sleep disorders. Correlation of five such SNPs with environmental variables supports a selective role of latitude or photoperiod, but certainly not a major one.

Higher bone mass in prepubertal and peripubertal female footballers.

OBJECTIVES: The main aim of this study was to compare the bone mass of female football players with controls of different pubertal stages. METHODS: Sixty five girls aged 8-14 years (10.14 ± 0.1, Tanner stages I-IV) participated in the study. Twenty participants were prepubertal (10 prepubertal control) and 45 peripubertal (15 peripubertal control). All footballers trained two days per week while the control group did not perform regular physical activity outside of school. Body composition was assessed by Dual-energy X-ray absorptiometry. Analysis of covariance was performed to evaluate differences in lean and bone masses. RESULTS: Significant differences in lower-body extremities lean mass (LLM) between peripubertal groups were found (P < .05). Additionally, prepubertal footballers showed higher values of bone mineral content (BMC) at the femoral neck (P < .05) while peripubertal footballers exhibited enhanced BMC at the whole-body, trochanter and Wards triangle area. Bone mineral density (BMD) was higher in footballers compared to their non-active peers at the femoral neck and intertrochanter (P < .05, respectively) while in the peripubertal footballers higher BMD values were found in almost all of the studied body sites. CONCLUSION: Female footballers showed higher bone and lean masses compared to control counterparts; these differences are already detectable at prepubertal ages and more consistent after pubertal spurt.

Fragility fracture risk and skeletal muscle function.

Low-intensity fractures are closely related with age-related musculoskeletal disorders, including osteoporosis, muscle dysfunction and sarcopenia, age-related chronic diseases, and pharmacological treatments. During the last years, a huge amount of information and recommendations has been released in relation to bone metabolism and mineral content. Muscle dysfunction and sarcopenia are highly prevalent during the second half of life, especially in older subjects. The development of sarcopenia may be slowed through healthy lifestyle changes, which include adequate dietary protein, vitamin D and mineral intakes, and regular physical activity. Prevention of falls should be integral, including correction in major involved factors in order to reduce fragility fracture, improve quality of life and appropriately focus clinical and economic resources. Therefore, to obtain better results a global approach is needed to prevent age-related fractures in frail patients that is not only centered on bone metabolism and antiresorptive drugs.

Mitochondrial coupling and capacity of oxidative phosphorylation in skeletal muscle of Inuit and Caucasians in the arctic winter.

During evolution, mitochondrial DNA haplogroups of arctic populations may have been selected for lower coupling of mitochondrial respiration to ATP production in favor of higher heat production. We show that mitochondrial coupling in skeletal muscle of traditional and westernized Inuit habituating northern Greenland is identical to Danes of western Europe haplogroups. Biochemical coupling efficiency was preserved across variations in diet, muscle fiber type, and uncoupling protein-3 content. Mitochondrial phenotype displayed plasticity in relation to lifestyle and environment. Untrained Inuit and Danes had identical capacities to oxidize fat substrate in arm muscle, which increased in Danes during the 42 days of acclimation to exercise, approaching the higher level of the Inuit hunters. A common pattern emerges of mitochondrial acclimatization and evolutionary adaptation in humans at high latitude and high altitude where economy of locomotion may be optimized by preservation of biochemical coupling efficiency at modest mitochondrial density, when submaximum performance is uncoupled from VO2max and maximum capacities of oxidative phosphorylation.

Maintained peak leg and pulmonary VO2 despite substantial reduction in muscle mitochondrial capacity.

We recently reported the circulatory and muscle oxidative capacities of the arm after prolonged low-intensity skiing in the arctic (Boushel et al., 2014). In the present study, leg VO2 was measured by the Fick method during leg cycling while muscle mitochondrial capacity was examined on a biopsy of the vastus lateralis in healthy volunteers (7 male, 2 female) before and after 42 days of skiing at 60% HR max. Peak pulmonary VO2 (3.52 ± 0.18 L.min(-1) pre vs 3.52 ± 0.19 post) and VO2 across the leg (2.8 ± 0.4L.min(-1) pre vs 3.0 ± 0.2 post) were unchanged after the ski journey. Peak leg O2 delivery (3.6 ± 0.2 L.min(-1) pre vs 3.8 ± 0.4 post), O2 extraction (82 ± 1% pre vs 83 ± 1 post), and muscle capillaries per mm(2) (576 ± 17 pre vs 612 ± 28 post) were also unchanged; however, leg muscle mitochondrial OXPHOS capacity was reduced (90 ± 3 pmol.sec(-1) .mg(-1) pre vs 70 ± 2 post, P < 0.05) as was citrate synthase activity (40 ± 3 µmol.min(-1) .g(-1) pre vs 34 ± 3 vs P < 0.05). These findings indicate that peak muscle VO2 can be sustained with a substantial reduction in mitochondrial OXPHOS capacity. This is achieved at a similar O2 delivery and a higher relative ADP-stimulated mitochondrial respiration at a higher mitochondrial p50. These findings support the concept that muscle mitochondrial respiration is submaximal at VO2max , and that mitochondrial volume can be downregulated by chronic energy demand.

Outcome of Percutaneous Tenotomy in the Management of Congenital Talipes Equino Varus by Ponseti Method.

Congenital talipes equino varus (CTEV) is a common complex congenital anomaly affecting approximately 1 per 900 live births in Bangladesh. Current trends in the treatment of idiopathic clubfoot have shifted from extensive surgical release to more conservative techniques. The Ponseti method that includes manipulation, serial casting, percutaneous tenotomy and bracing has recently become very popular for the management of CTEV with reported excellent outcomes. The purpose of this study was to evaluate the outcomes of Percutaneous Tenotomy in the treatment of equinus deformity of idiopathic clubfoot. Between June 2012 and November 2013 we treated 47 feet in 34 children by the Ponseti method. The standard protocol described by Ponseti was used. Percutaneous tenotomy of the Achilles tendon was performed under local anaesthesia in the outpatient department of Dhaka Medical College Hospital. The Pirani score was used for assessment and mean follow up time was 12 months. The compliance of percutaneous tenotomy among the 47 feet was recorded and 40(85.1%) were good, 4(8.5%) were fair and 3(6.4%) were poor. The rating of final outcome of percutaneous tenotomy after one year follow-up periods among 47 feet, 36(76.6%) were good, 11(23.4%) were fair and zero (0%) were poor. This study permits to conclude the percutaneous tenotomy in Ponseti method as a safe, effective outdoor procedure to correct the residual equinus deformity of club foot after serial casting.
