Assessment of Foot Shape in Children and Adolescents with Intellectual Disability: A Pilot Study.

BACKGROUND Available publications provide little evidence pertaining to assessment of foot shape in children with intellectual disability. The aim of this study was to assess the parameters of foot shape in children and adolescents with intellectual disability and to evaluate the relationship between the degree of disability and these parameters. MATERIAL AND METHODS The study involved 90 individuals aged 7-15 years, including 45 subjects with mild and moderate levels of intellectual disability (study group) and 45 peers with normal intellectual development (control group). Each participant was subjected to photogrammetric assessment of foot shape based on the projection moire effect. RESULTS Analysis of the relationship between the disability level and the assessed parameters showed that the length of the right (p=0.006) and left (p=0.004) foot, as well as Wejsflog's rate for the right (p<0.001) and left (p<0.001) foot, were significantly higher among children with mild disability, whereas GAMMA angle of the right (p=0.028) and left (p=0.006) foot was significantly higher among children with moderate disability. CONCLUSIONS The findings show a significant relationship between the degree of disability and the assessed foot parameters. Significant differences between the subjects with intellectual disability and the control group were identified in the basic parameters defining foot structure.

Concurrent validity of photogrammetric and inclinometric techniques based on assessment of anteroposterior spinal curvatures.

PURPOSE: The purpose of the study was to investigate correlations between parameters of anteroposterior spinal curvatures in the sagittal plane, measured with the use of photogrammetric technique and inclinometer in healthy elderly women. METHODS: Randomized study involved 50 females, ranging from 50 to 70 years of age (mean 62.26 ± 6.94); mean body mass index (BMI) 27.69 ± 4.79. The examined parameters included angle of inclination in lumbosacral spine (ALFA), thoracolumbar transition (BETA), upper thoracic segment (GAMMA), angle of lumbar lordosis (LLA) and thoracic kyphosis (TKA). Results obtained with gravitational inclinometer were compared with those identified with photogrammetry method. Statistical analyses were performed with Mann-Whitney U test, regression analysis and Bland-Altman analysis. RESULTS: In Mann-Whitney U test, with correction due to continuity, no statistically significant differences for any variable were found. Regression analysis was significant only for the variable of BETA angle. Bland-Altman coefficient for the respective angles was: ALFA 2.0%, BETA 4%, GAMMA 0%, LLA 2% and TKA 0%. CONCLUSIONS: The results acquired with gravitational inclinometer and with photogrammetric technique are comparable, as the parameters of anteroposterior spinal curvatures acquired with these two methods are found to be compatible in the case of measurements of lumbar lordosis and thoracic kyphosis.

Analysis of Anteroposterior Spinal Curvatures in Child Violinists from Music Schools.

Young musicians often report problems with their upper limbs and spine due to their specific and asymmetric positions and actions while playing, which may contribute to overloading these structures. Diagnosing any disorders to the upper limbs or spine early may help to minimize the risk of developing any serious instrument-related health problems in the future. The aim of this study was to assess the anteroposterior (AP) spinal curvatures in children learning to play the violin. Previous studies have shown anthropomorphic differences in young adult musicians, and our study examined if these differences appeared early or late in the musician's career. METHODS: Body posture of 101 children, aged 7-12 yrs (mean 11.09±1.48), was assessed. The study population consisted of 49 child violinists and a control group of 52 children who did not play any musical instrument. There were 81.19% girls and 18.81% boys. Body posture was analyzed using the MORA 4G. RESULTS: The violinist group showed significant differences in the thoracolumbar region angle (p=0.004) compared to the non-musical children. The remaining parameters did not reveal significant differences between groups. The parameter characterizing the location of kyphosis peak calculated from the spinous process of the C7 vertebra was significantly higher in the study population. CONCLUSIONS: Changes in body posture in children who play the violin appear early in their training. Body postures when playing the violin lead to some changes in parameters characterizing AP spinal curvatures in the sagittal plane.

Comparison of parameters characterizing lumbar lordosis in radiograph and photogrammetric examination of adults.

OBJECTIVE: The purpose of this study was to test validity of photogrammetry compared with radiography as a method of measuring the Cobb angle and the size of anterior-posterior spine curvatures in adults. METHODS: The study included 50 volunteers, 23 men and 27 women whose mean age was 52.6 years. The average weight of the subjects was 81.3 kg, average body height was 172.0 cm, and the average body mass index was 27.4. Based on radiologic examination, the length and depth of lumbar lordosis were determined and the size of the Cobb angle of lumbar scoliosis. After the radiologic examination, a photogrammetric test was performed for each subject with the projection moire phenomenon. RESULTS: The Pearson correlation found statistically significant associations concerning the length of lordosis (P < .001) and the Cobb angle (P < .001). Correlation of the depth of lordosis indicated a strong trend (P = .063). CONCLUSIONS: This study found that the moire method of photogrammetric measurement produced similar findings to radiographic measurements in determining size of the Cobb angle and the length of lumbar lordosis.

Evaluation of functional outcomes in individuals 10 years after posterior lumbar interbody fusion with corundum implants and decompression: a comparison of 2 surgical techniques.

BACKGROUND: The purpose of this study was to evaluate lumbar spine-related functional disability in individuals 10 years after lumbar decompression and lumbar decompression with posterior lumbar interbody fusion (PLIF) with corundum implants surgery for degenerative stenosis and to compare the long-term outcome of these 2 surgical techniques. MATERIAL/METHODS: From 1998 to 2002, 100 patients with single-level lumbar stenosis were surgically treated. The patients were randomly divided into 2 groups that did not differ in terms of clinical or neurological symptoms. Group A consisted of 50 patients who were treated with PLIF and the use of porous ceramic corundum implants; the mean age was 57.74 and BMI was 27.34. Group B consisted of 50 patients treated with decompression by fenestration; mean age was 51.28 and the mean BMI was 28.84. RESULTS: There was no statistical significance regarding age, BMI, and sex. Both treatments revealed significant improvements. In group A, ODI decreased from 41.01% to 14.3% at 1 year and 16.3 at 10 years. In group B, ODI decreased from 63.8% to 18.36% at 1 year and 22.36% at 10 years. The difference between groups was statistically significant. There were no differences between the groups regarding the Rolland-Morris disability questionnaire and VAS at 1 and 10 years after surgery. CONCLUSIONS: Long-term results evaluated according to the ODI, the Rolland-Morris disability questionnaire, and the VAS showed that the both methods significantly reduce patient disability, and this was maintained during next 10 years. The less invasive fenestration procedure was only slightly less favorable than surgical treatment of stenosis by both PLIF with corundum implants and decompression.

The effect of spinal curvature on the photogrammetric assessment on static balance in elderly women.

BACKGROUND: Involutional changes to the body in elderly patients affect the shape of the spine and the activity of postural muscles. The purpose of this study was to assess the influence of age-related changes in spinal curvature on postural balance in elderly women. METHODS: The study population consisted of 90 women, with a mean age of 70 ± 8.01 years. Static balance assessments were conducted on a tensometric platform, and posturographic assessments of body posture were performed using a photogrammetric method based on the Projection Moiré method. RESULTS: The results obtained were analysed using the Spearman's rank correlation coefficient test. We found a statistically significant correlation between body posture and the quality of the balance system response based on the corrective function of the visual system. The shape of the spinal curvature influenced postural stability, as measured by static posturography. Improvement in the quality of the balance system response depended on corrective information from the visual system and proprioceptive information from the paraspinal muscles. CONCLUSIONS: The sensitivity of the balance system to the change of centre of pressure location was influenced by the direction of the change in rotation of the shoulder girdle and spine. Development of spinal curvature in the sagittal plane and maintenance of symmetry in the coronal and transverse planes are essential for correct balance control, which in turn is essential for the development of a properly proportioned locomotor system.

A comparative analysis of static balance between patients with lumbar spinal canal stenosis and asymptomatic participants.

OBJECTIVE: The aim of this study was to assess static balance in patients with lumbar spinal canal stenosis who qualified for surgical decompression of associated neural structures and compare them with asymptomatic participants. METHODS: This case-controlled study evaluated a sample of 50 patients with spinal canal stenosis (stenosis group) and 48 participants with no history of clinical symptoms of back pain. Static balance was assessed by conducting quantitative analysis of balance reaction parameters in quiet standing with the eyes closed. RESULTS: Higher values were observed in total length of center of pressure (COP) path, length of COP path in the anterior-posterior plane, mean amplitude of COP projection in the anterior-posterior plane, maximal amplitude between the 2 most distant points in the anterior-posterior plane, mean COP velocity, and sway area marked by the moving COP in the stenosis group compared with the asymptomatic group. CONCLUSIONS: This study showed statistically significant differences in static balance parameters between patients with spinal canal stenosis compared with the asymptomatic group.

Study of the influence of lipids on the balance parameters in patients with well and poorly controlled arterial hypertension.

STUDY AIM: To assess the correlation of the level of cholesterol fractions and balance in two groups of patients with well and poorly controlled hypertension. MATERIAL AND METHODS: The study included 106 patients: 41 males and 65 females with diagnosed arterial hypertension without concomitant diseases which could affect the balance system. The average age of the patients was 52.1 +/- 7.7 years. The values of the level of individual lipid fractions from the previous three months were obtained from the medical records of the patients. The influence of the cholesterol fractions in the patient group with well and poorly controlled hypertension on balance parameters was assessed. The balance examination was conducted on a stabilometric platform. RESULTS: The study results indicate a correlation between balance disorders and the increase of cholesterol levels in people with hypertension regardless of its level of control. Patients with uncontrolled hypertension more frequently presented a deterioration of the balance parameters examined on the stabilometric platform. The increase in the level of the LDL cholesterol fraction was associated with a deterioration of the balance parameters only in the group with uncontrolled hypertension, both in the eyes open and eyes closed test. The increase in the level of cholesterol and its individual fractions in combination with arterial pressure above 140/90 mmHg in our study deteriorated the balance parameters for the distance traveled, velocity of movement and the size of the area marked by the projection of the center of gravity in the examined persons. CONCLUSIONS: Disorders of lipid balance may be associated with changes in the balance system and accelerate their development in people under 60 years of age, which translates to worse balance parameters achieved in the stabilometric platform test, especially

Changes in the body posture of women occurring with age.

BACKGROUND: A current topic in the field of geriatrics still needing a great deal of study is the changes in body posture occurring with age. Symptoms of these changes can be observed starting between the ages of 40-50 years with a slow progression that increases after 60 years of age. The aims of this study were to evaluate parameters characterizing the posture of women over the age of 60 years compared with a control group and to determine the dynamics of body posture changes in the following decades. METHODS: The study included 260 randomly selected women. The study group consisted of 130 women between the ages of 60-90 years (Older Women). The control group (Younger Women) consisted of 130 women between the ages of 20-25 years (posture stabilization period). The photogrammetric method was used to evaluate body posture using the phenomenon of the projection chamber. The study was conducted according to generally accepted principles. RESULTS: In the analysis of parameters characterizing individual slope curves, results were varied among different age groups. The lumbar spine slope did not show significant differences between different age groups (p = 0.6952), while statistically significant differences (p = 0.0000) were found in the thoracic-lumbar spine slope (p = 0.0033) and upper thoracic spine slope. Body angle was shown to increase with age (p = 0.0000). Thoracic kyphosis depth significantly deepened with age (p = 0.0002), however, the thoracic kyphosis angle decreased with age (p = 0.0000). An increase in asymmetries was noticed, provided by a significantly higher angle of the shoulder line (p = 0.0199) and the difference in height of the lower shoulder blade angle (p = 0.0007) measurements in the group of older women. CONCLUSIONS: Changes in the parameters describing body posture throughout consecutive decades were observed. Therapy for women over the age of 60 years should involve strengthening of the erector spinae muscles and controlling body posture with the aim of reducing trunk inclination and deepening of thoracic kyphosis. Moreover, exercises shaping lumbar lordosis should be performed to prevent its flattening.

Effects of carrying a backpack in a symmetrical manner on the shape of the feet.

The aim of this study was to assess changes in the shape of the feet while carrying a backpack constituting 10% of a child's weight. It was an observational, cross-sectional study involving 118 primary school children aged 11-13 years. Selected parameters of foot shape were assessed in both a normal position and with a backpack using podoscopy and a CQ-ST examination device. The study revealed significant differences in the length and width of the right and left feet between assessments. Moreover, the longitudinal arch of the foot was significantly lowered and deformity of the great toe was reported. Carrying a backpack constituting 10% of a child's weight results in lowering of the longitudinal and traverse arches of the feet and advanced toe deformities. PRACTITIONER SUMMARY: We performed an observational, cross-sectional study examining the effect of carrying a backpack constituting 10% of a child's weight on parameters of foot shape and observed significant lowering of the longitudinal and traverse arches of the feet and advanced toe deformities.

Back pain and body posture of non-professional Brazilian Jiu-Jitsu practitioners.

Background: The aim of the study was to assess the prevalence of back pain in non-professional Brazilian Jiu-Jitsu practitioners (NP-BJJ practitioners), and to assess the relationship between their back pain and postural disorders. Methods: The study involved 61 subjects (age: 30.7 ± 4.9 years old; body mass: 79.4 ± 12.9 kg; body height: 179.6 ± 8.4 cm; 8 woman and 53 man), 31 who trained Brazilian Jiu-Jitsu (BJJ) and 30 subjects who had never trained any combat sport. The mean time of training BJJ in the study population was 3.9 ± 4.1 years. Postural assessments were conducted with the use of the photogrammetric method. The assessment of back pain and injuries was conducted with the Oswestry Disability Index (ODI) and with our proprietary questionnaire. Results: Among both populations, 37 subjects reported back pain. There were no differences in back pain location between the two groups or in functional state on the ODI. Significant differences between the groups in the values of the postural parameters (spinal height, length of kyphosis, length of lordosis, pelvis inclination angle) were observed. Statistically significant differences between the NP-BJJ practitioners with and without back pain in the length of the thoracic kyphosis and the differences in the height of the waist triangles were found. Conclusions: Both in the study population and in the control group the spinal pain was minimal or moderate on the ODI. BJJ practitioners who reported back pain had characteristic postural changes in some of the analysed postural parameters in comparison to BJJ practitioners who did not report back pain.

Postural stability disorders-early signs of aging-in physically non-active prisoners.

BACKGROUND: There is a need for a study of possible relationship between serving a prison sentence and developing postural stability dysfunction. The aim of the study was to analyze postural stability of physically inactive prisoners. The study group consisted of 24 male prisoners aged 34.6 ± 7.02 years, imprisoned in closed prison and 30 healthy, non-active physically, aged 36.9 ± 7.5 years, who consisted control group. The subjects were imprisoned for a mean of 105.43 ± 58.48 months. METHODS: The static balance test was conducted on bi-modular stabilometric platform CQStab2P. RESULTS: We found statistically significant differences in several stability parameters. Prisoners results were significantly worse in parameters measured with eyes open: MA (mean amplitude p < 0.01), MAAP (mean amplitude in anterio-posterior plane p < 0.03), MAML (mean amplitude in medio-lateral plane p < 0.04), MaxAP (maximal sway in AP p < 0.01), MaxML (p < 0.01). With eyes closed the prisoner's results were significantly worse in SPML (sway path in medio-lateral plane p = 0.01), better in MAML (p < 0.01) and MaxML (p < 0.01), and faster in MVML (mean velocity in medio-lateral plane p < 0.01). CONCLUSIONS: (1) Diagnostics aimed at early diagnoses of ageing symptoms should be performed in prisons. It would allow for better prisoner management in terms of assessment of ability to work, free time activity offer and falls prevention. (2) In prisons, in addition to counteracting the typical causes of balance disorders, action should be taken to counteract the causes for balance disorders typical for prison environment, inter alia: sensory deprivation-by implementing programmes comprehensively activating prisoners, and hypokinesis-by implementing physical activity programmes that cater for the needs of older prisoners.

Balance and functional disorders in geriatric patients after total hip prosthesis removal.

BACKGROUND: One of the most difficult complications of total hip arthroplasty is an infection in the area of the implant with an incidence of 0.5% to 2.5% resulting in the most severe situation in prosthesis removal. OBJECTIVE: The aim of the study was to assess postural stability and functional disorders in patients after hip prosthesis removal. METHODS: A group of 15 patients after hip prosthesis removal was compared to a control group of 15 healthy persons who were age-matched without any symptoms of degenerative disorders in the lower spine and lower extremities. The static balance test was conducted on a bi-modular stabilometric platform, registering the movement of the centre of foot pressure. The functional state of the patients was assessed on the basis of the Harris Hip Score (HHS). RESULTS: Patients had poor functional result (HSS mean 62.29 ± 12.92 points). Obtained results of postural stability of patients showed huge difficulties maintaining stability and showed statistically significant differences in a majority of the analysed parameters. CONCLUSIONS: Several stability parameters showed significantly worse results in patients after hip prosthesis removal. Special attention should be paid and focused physiotherapy should be undertaken for patients with a stability disorder and functional status to prevent falls and improve functioning.

Postural stability and functional disorders in patients with loosened hip prosthesis.

PURPOSE: The number of primary hip arthroplasties is growing every year. One of the most common long complications is the aseptic loosening of the prosthesis leading to serious complications in patients life, pain and following surgeries. In the literature, there is a lack of studies regarding balance impairment in this group of patients, which is why there was a need to conduct the study in order to find possible falling risk factors and simple functional, diagnostic test. The aim of the study was to assess functional state and static balance disorders in patients admitted to orthopaedic department due to loosened hip prosthesis prior to its replacement or removal. METHODS: The study population were 30 patients (15 women and 15 men) admitted to Orthopaedic Department for diagnosis and treatment of loosened hip prosthesis. Patients' mean age was 71.67 ± 9.21, body height 169.20 ± 8.75 cm, body weight 77.83 ± 12.96 kg. The clinical control group consisted of 30 healthy subjects age-, body height- and weight-matched, without degenerative disorders of lower extremities. Function was assessed with Harris Hip score. The static balance test was conducted in the mornings, in quiet separate room on bi-modular stabilometric platform CQStab2P, registering the movement of centre of foot pressure (COP). RESULTS: Measurements with eyes open and closed showed significant differences in limb loads - the load to the healthy limb was several times greater. Results of tests on the platform with eyes closed showed significantly worse balance in patients group. Their total statokinesiogram path was longer, and their COP sways number was greater. Similarly to the test with eyes open, the load of the healthy limb was much greater. CONCLUSION: Hip replacement loosening results in significant worsening of balance parameters. Balance assessment could be an additional useful diagnostic tool for hip replacement loosening available for physiotherapists.

Body Fat and Muscle Mass in Association with Foot Structure in Adolescents: A Cross-Sectional Study.

Prior studies have investigated associations between body mass index (BMI) and foot structure; however, these studies are limited only to the evaluation of the longitudinal arch of the foot and do not evaluate associations with body composition. Therefore, this study examined associations between body fat percentage (BFP) and muscle mass percentage with foot structure in adolescents. This study was conducted with 158 healthy subjects aged from 11 to 13 years. Body fat percentage and muscle mass percentage were estimated using bioelectrical impedance analysis. A podoscope was used to calculate Clarke's angle (CL), the Wejsflog index (WI), hallux valgus angle (ALPHA), and the angle of the varus deformity of the fifth toe (BETA). Lower values of CL were found in participants with excessive BFP (p = 0.021). No differences were observed in the values of the Wejsflog, ALFA or BETA indices between normal and excessive BFP groups. Participants with the lowest muscle mass percentage were significantly more likely to have lower values of CL and WI (p = 0.014 and p < 0.001, respectively). Excess BFP appeared to have a significant effect on the longitudinal arch and low muscle mass percentage on the longitudinal and transverse arches of the foot in adolescents. There was no association between fat and muscle content with positions of the big and fifth toes.

Agreement of Three Posturographic Force Plates in the Assessment of Postural Stability.

This study was designed to assess how the results obtained for three different posturographic platforms agreed with each other in an assessment of static postural stability. The study included 111 young healthy participants. A measurement of postural stability was made for each participant, with their eyes open and then closed, on each platform in a random order. The Romberg ratio, path length, and center of pressure (COP) area were analyzed. For all measures, significant differences (p < 0.05) were observed among the three force plates. The highest Spearman's rank correlation was observed between Alfa vs. CQStab2P (0.20 to 0.38), and the lowest between Alfa vs. AccuGait (-0.19 to 0.09). Similar results were obtained for the concordance correlation coefficient (0.10 to 0.22 for Alfa vs. CQStab2P and -0.6 to 0.02 for Alfa vs. AccuGait). Bland-Altman analysis for values standardized (z-scores) against AccuGait indicated a low level of agreement between compared platforms, with the largest error between AccuGait vs. Alfa, and a slightly lower error between AccuGait vs. CQStab2P or Alfa vs. CQStab2P. The 95% limits of agreement ranged from 2.38 to 7.16 (Alfa vs. AccuGait), 2.09 to 5.69 (CQStab2P vs. AccuGait), and 1.39 to 7.44 (AccuGait vs. Alfa) in COP length with eyes open and COP length Romberg ratio, respectively. Special care is recommended when comparing values relating to COPs from different devices that are analyzed by different software. Moreover, unperturbed stance tests among young healthy adults can be questioned as a valid postural control parameter.

Evaluation of vitamin D3 levels and morphotic parameters of blood in prematurely born children at six years of age.

In Poland the preterm children, with the birth rate reaching 6.3%, constitute a serious medical problem. The system of specialistic clinics provides them with the multidisciplinary care for the first 3 years of life, including the monitoring of hematologic parameters in relation with anemia and osteopenia. The aim of this study was to assess the vitamin D3 level and morphotic parameters of blood in children who were prematurely born at the time when they are about to start school. The study was carried out in a group of 92 children, aged 6 years ±0.63, including 54 preterm children born at gestational age <32 weeks - and 38 full-term children. A basic anthropometric measures and assessment of morphotic parameters and the vitamin D3 level were assessed. Statistical analyses were carried out using Shapiro-Wilk W-test, Student's t-test and Mann-Whitney U test. Preterm children had significantly lower the vitamin D3 level than controls. This also refers to some morphotic parameters of blood, such as level of hemoglobin, mean corpuscular hemoglobin concentration and platelets. Prematurely born 6-7 year-old children have significantly lower vitamin D3 levels in blood serum than normal and significantly lower hemoglobin levels than full-term children.

Assessment of body adiposity preterm children at the beginning of school age.

In Poland, like in other developed countries, 6.3% of babies are born prematurely. Preterm babies suffer from numerous health issues. The aim of the study was to assess body adiposity in preterm children at the beginning of school age. The study population consisted of 61 children aged 5 to 8 years who had been born preterm. We performed standard anthropometric measurements according to internationally recognized methodology. The following parameters were used: Body Weight (BW), Body Heigh (BH), Waist Circumference (WC), Body Mass Index (BMI), Waist to Height Ratio (WtHR), Triceps Skinfold Thickness (TST), Subscapular Skinfold Thickness (SST), Umbilical Skinfold Thickness (UST), as well as total sum of the above parameters, or the Global Adiposity (GA). The anthropometric measurements were taken according to international anthropometric methodology. All anthropometric parameters for body adiposity were significantly lower in the study population than in the reference system. We found a statistically significant relationship between: the number of fetuses and: UST (p = 0.007) and z-score UST (p = 0.030); combined number of unfavorable perinatal events: and UST (p = 0.013) and z-score UST (p = 0.007), GA (p = 0.038) and z-score GA (p = 0.040). Preterm children who are about to start school have significantly lower values of anthropometric features that characterize their body adiposity. In preterm children at early school age number of fetuses diversifies UST; and combined number of unfavorable perinatal events diversifies UST and GA. It is recommended that more studies are conducted on positively oriented modification of body adiposity in these children, as well as its long term monitoring.

Urinary incontinence due to lumbar spinal stenosis causing disability and lowering quality of life.

OBJECTIVES: Lumbar spinal stenosis may lead to urinary inconsistence and can have a negative impact on the quality of life. The aim of the study was to assess the incidence of urinary incontinence and quality of life in female patients with spinal canal stenosis comparing to control group. METHODS: The study population consisted of 50 women diagnosed with severe lumbar spinal canal stenosis. Their mean age was 55.32 ± 12.97 years. The clinical control group consisted of 30 women who did not suffer from any spine disorders. Their mean age was 54.87 ± 12.01 years. There was no difference between both groups regarding age, weight, BMI and number of parity. The women diagnosed with clinical and radiographic symptoms of spinal canal stenosis filled out an anonymous questionnaire, ODI, ICIQ-UI-SF, and ICIQ-LUTSqol questionnaires. RESULTS: We found urinary incontinence in 56% of women with lumbar spinal canal stenosis and in 43% of clinical control group. We also found a statistically significant correlation between duration of lumbar stenotic symptoms, the SLR sign, number of deliveries and the intensity of urinary incontinence. CONCLUSIONS: Urinary incontinence in women with lumbar spinal canal stenosis is significantly different from the control group. Leakage of urine happened more frequently, the amount of urine leaked was greater, and the general impact on everyday life is harsher, as compared to the clinical control group.
