Effects of electrical stimulation program on trunk muscle strength, functional capacity, quality of life, and depression in the patients with low back pain: a randomized controlled trial.

The aim of this clinical trial was to evaluate the effects of electrical stimulation (ES) program on trunk muscle strength, functional performance, quality of life (QOL) in the patients with chronic low back pain (CLBP). A total of 41 patients with definite CLBP were included in this study. These patients were randomized into two groups. Group 1 (n = 21) was given an ES program and exercises. Group 2 (n = 20) was accepted as the control group and given only exercises. Both the programs were performed 3 days a week, for 8 weeks in the out-patient department. The patients were evaluated according to pain, disability, functional performance, endurance, quality of life, depression. The muscle strengths were measured with a hand-held dynamometer. There were significant improvements for all the parameters in two groups after the treatment. Except depression and social function, the improvements for all the parameters were better in the ES group than in the control group. We observed that ES program was very effective in improving QOL, functional performance and isometric strength. In conclusion, we can say that ES therapy provides comfortable life functions by improving muscle strength, functional performance and QOL.

The relationship of illness perceptions with demographic features, pain severity, functional capacity, disability, depression, and quality of life in patients with chronic low back pain.

OBJECTIVES: The aim of this study was to evaluate the relationship of illness perceptions (IPs) with demographic features, severity of pain, functional capacity, disability, depression, and quality of life in patients with chronic low back pain (CLBP). PATIENTS AND METHODS: Between January 2015 and July 2015, a total of 114 patients with non-specific CLBP (86 females, 28 males; mean age 47.1±15.2 years; range, 18 to 85 years) were included. Non-specific CLBP was defined as low back pain not attributable to a recognizable, known specific pathology such as infection, tumor, inflammation for ≥12 weeks. The IPs using the revised Illness Perception Questionnaire (IPQ-R), pain severity using the visual analog scale (VAS), functional capacity using the Six-Minute Walk Test (6MWT), disability using the modified Oswestry Disability Index (m-ODI), depression using the Beck Depression Inventory (BDI), and quality of life using the Short Form-36 (SF-36) were assessed. RESULTS: There was a significant, positive correlation between the age, body mass index, duration of disease, pain scores, and IPQ-R- consequences, timeline (acute/chronic), and emotional responses subunits, whereas there was a significant, negative correlation between the IPQ-R-personal and treatment control subunits (p<0.001). The IPQ-R-timeline (acute/chronic), consequences, and emotional response subunits were positively and personal and treatment controls and illness coherence subunits were negatively correlated with the BDI and m-ODI (p<0.001). The IPQ-R-consequences and emotional responses subunits were negatively and timeline (acute/chronic), personal and treatment controls, and illness coherence subunits were positively correlated with the SF-36 subunits (p<0.05). CONCLUSION: The IPs were negatively affected by advanced age, high body mass index, longer duration of disease, and increased severity of pain in CLBP patients. Based on these findings, positive IPs may be related with reduced disability and depression, and improved quality of life and functional capacity in this patient population. Developing new strategies for improving the negative IPs of patients with CLBP may be useful.

Falls, fear of falling, and associated factors in ambulatory patients with rheumatoid arthritis: A comparative study with healthy controls.

OBJECTIVES: This study aims to compare fall history and fear of falling (FOF) in patients with rheumatoid arthritis (RA) and healthy controls and to evaluate associated factors for fall risk and FOF in patients with RA. MATERIALS AND METHODS: Between March 2016 and July 2016, a total of 120 patients with RA and 60 age- and sex-matched healthy volunteers were included in the study. The presence of FOF (Yes/No), fall history, and the number of falls within the past 12 month were questioned. All participants were assessed with the Falls Efficacy Scale-International (FES-I), 10 Meter Walk Test (10MWT), One-Leg Stand Test (OLST), Berg Balance Scale (BBS), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). Pain Severity and Patient Global Assessment (PGA) by Visual Analog Scale (VAS), disability by the Health Assessment Questionnaire (HAQ), and disease activity by Disease Activity Score in 28 joints (DAS28) were evaluated in patients with RA. RESULTS: There was no statistically difference between the RA patients and healthy controls in terms of presence of fall history, while the presence of FOF and FES-I scores were significantly higher in the RA patients (p<0.05). In the patient group, the FES-I score was positively correlated with pain VAS, PGA, DAS-28, HAQ, BAI, BDI, and 10MWT and negatively BBS and OLST (p<0.05). The number of falls, HAQ, BBS, and BDI scores were found to be significant independent risk factors affecting variations in the FES-I scores (p<0.001). CONCLUSION: Fear of falling seems to be an important problem in patients with RA, and patients without fall history may also have FOF. The most important factors associated with FOF were impaired balance, increased disability and depression, and number of falls in RA patients. Strategies for preventing falls, maintaining balance, improving emotional status and against FOF are of utmost importance in patients with RA.

Are Illness Perceptions Associated With Disease Activity or Psychological Well-Being in Rheumatoid Arthritis? A Study With the Evidence of Confirmatory Factor Analysis.

OBJECTIVES: This study aims to assess the factor structure of the Turkish Revised Illness Perception Questionnaire (IPQ-R) in patients with rheumatoid arthritis (RA) and the relationship of illness perceptions with disease activity and psychological well-being. PATIENTS AND METHODS: One hundred and fifty RA patients (8 males, 142 females; mean age 51.1±12.7 years; range 21 to 81 years) were included in the study. Confirmatory factor analysis was used to test the factor structure of the IPQ-R. Pain was assessed by visual analog scale, disease activity by Disease Activity Score 28, depression by Beck Depression Inventory, global life satisfaction by the Satisfaction with Life Scale, and illness perception by the IPQ-R. RESULTS: Three items (items 12, 18, 19) were deleted because of poor factor loadings. The modified 35-item model showed good reliability and discriminant validity. Beck Depression Inventory scores were correlated with identity, consequences, and emotional representations subscales positively (p<0.001); and with illness coherence subscale negatively (p<0.05). There were positive correlations between Satisfaction with Life Scale scores, and treatment control and illness coherence subscales (p<0.05). Satisfaction with Life Scale scores were negatively correlated with identity, emotional representation, and timeline acute/chronic subscales (p<0.05), and consequences subscale (p<0.001). Disease Activity Score 28 was not correlated with IPQ-R domains (p>0.05). CONCLUSION: The Turkish IPQ-R appears to be a useful clinical assessment tool to evaluate RA-related illness perceptions. RA healthcare should include psychological intervention to strengthen patients' beliefs about their RA regardless of disease activity.

Reliability and Validity of the Turkish Adaptation of VITACORA-19 in Patients with Psoriatic Arthritis.

OBJECTIVES: This study aims to evaluate the reliability and validity of the Turkish language version of VITACORA-19 (psoriatic arthritis quality of life questionnaire) in patients with psoriatic arthritis. PATIENTS AND METHODS: The Turkish version of VITACORA-19 questionnaire was obtained after a translation and back translation process. The study sample included 61 PsA patients (22 males, 39 females; mean age 46.5±12.2 years; range 19 to 71 years). To assess the test-retest reliability of the Turkish VITACORA-19, the questionnaire was reapplied 10 to 15 days after the first interview (interclass correlation coefficient). Cronbach's alpha (a) was used to evaluate the internal consistency. VITACORA-19 was compared with visual analog scale for physician and patient global assessments, the Health Assessment Questionnaire, and Nottingham Health Profile for construct validity. The internal structure of VITACORA-19 was examined by factor analysis. RESULTS: The individual item intraclass correlation coefficient ranged from 0.77 to 0.98 and Cronbach's alpha ranged from 0.77 to 0.98. The Cronbach's alpha value for whole scale was determined as 0.96. The Kaiser-Meyer-Olkin measure of sampling adequacy was 0.90, and Bartlett's test of sphericity had a p<0.001. Turkish VITACORA-19 total scores were correlated negatively with Health Assessment Questionnaire, visual analog scale for pain, and Nottingham Health Profile subgroups, and positively with physician and patient global assessments (p<0.01). CONCLUSION: Turkish version of VITACORA-19 questionnaire is a reliable and valid measure for health-related quality of life in Turkish patients with psoriatic arthritis.

Bladder exstrophy: effects on bone age, bone mineral density, growth, and metabolism.

Bladder exstrophy patients with or without augmentation have not been investigated according to metabolic bone problems, bone ages and growth, and development in details yet. We studied alterations in growth, bone ages, biochemistry of bone, bone mineral densities (BMD) of the forearm, neck of femur and lumbar vertebrae, blood gases, glomerular filtration rates (GFR), and electrolytes of 15 bladder exstrophy patients with augmentation and in those who had no augmentation. In six patients, a sigmoid colon was used for bladder augmentation and one patient underwent a ureterosigmoidostomy. Growth charts of all children were analyzed for determination of the percentiles. The parameters were compared with normal children and a comparison between augmented and nonaugmented patients were made. Growth retardation and decreased bone age were detected in all of the children. Ten patients with bladder exstrophy were below the 10th percentile for height. The mean age/bone age ratio of the patients was 1.59. The mean lumbar and femoral Z scores of the patients were -1.00 and -0.49, respectively. Mean BMD for distal radius was 0.239 g/cm2. Seven patients had a marked BMD decrease, their femoral and/or lumbar Z scores were below -1. Four cases had a pH lower than 7.35. In five patients, a HCO3 level less than 19 mmol/l was detected, four of them had an augmentation. Chloride measurements were slightly increased in six patients and alkaline phosphatase levels in five cases. Reduced GFR values were detected in two patients. There were no significant difference in laboratory values, in percentile height, and weights, in BMDs of femur, vertebra, forearm nor were any differences noted in age/bone age ratios in patients with augmentation when compared with those who had no augmentation. We found varying alteration in bone mineral density and HCO3 levels in patients with bladder exstrophy. Patients with bladder exstrophy, with or without augmentation, may develop serious growth retardation. As much as 45% of them, regardless of presence of augmentation, have an osteopenia or osteoporosis. We found a considerable difference in percentiles of heights as well as bone ages in bladder exstrophy patients when compared with normal population. We recommend close follow up of children with bladder exstrophy for linear growth, development of osteopenia, and bone ages.

Spondyloarthritis Research Consortium of Canada (SPARCC) enthesitis index in Turkish patients with ankylosing spondylitis: relationship with disease activity and quality of life.

AIM: The aim of this study was to investigate the relationship between Spondyloarthritis Research Consortium of Canada (SPARCC) enthesitis index and disease activity and health-related quality of life in patients with ankylosing spondylitis (AS). METHODS: Eighty-six AS patients not receiving antitumour necrosis factor (TNF) therapy were included in the study. Spinal pain by visual analogue scale (pain VAS rest and activity), disease activity by Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), functional capacity by Bath Ankylosing Spondylitis Functional Index (BASFI), enthesitis severity by SPARCC index, quality of life by Short Form-36 (SF-36), and Bath Ankylosing Spondylitis Metrology Index (BASMI) were assessed in patients. In the laboratory evaluations, the erythrocyte sedimentation rates and serum C-reactive protein levels of the patients were determined. RESULTS: All participants were aged between 18 and 65 years, with a mean age of 36.9 ± 11.13 years. The most frequent region of enthesitis was Achilles tendon insertion into calcaneum (55.8%). Pain VAS rest and activity, BASFI and all parameters of SF-36 were significantly different in AS patients with and without enthesitis. SPARCC index was significantly correlated with pain VAS activity (P < 0.05), pain VAS rest, BASDAI, BASFI and all parameters of SF-36 (P < 0.001). There were no correlations between SPARCC index and BASMI, disease duration and laboratory parameters (P > 0.05). CONCLUSION: The clinical assessment of enthesitis in AS is an important outcome measure, and enthesitis indexes such as SPARCC enthesitis index can be valuable tools in the evaluation of disease activity in AS patients not receiving anti-TNF therapy.

Association between osteoporosis and polymorphisms of the IL-10 and TGF-beta genes in Turkish postmenopausal women.

Osteoporosis is a multifactorial disease in which genetic determinants are modulated by hormonal, environmental and nutritional factors. The balance between bone resorption and bone formation seems to be regulated by a variety of growth factors and cytokines. An important clinical risk factor in the pathogenesis of osteoporosis is the presence of genetic polymorphisms in susceptibility genes. In this study, we investigated the association between osteoporosis and interleukin 10 (IL-10) -597 C > A and transforming growth factor ß1 (TGF-ß1) T869C (also named Leu10 > Pro) polymorphisms in Turkish postmenopausal women. Genomic DNA obtained from 255 individuals (152 osteoporotic and 103 healthy controls). The DNA sample was isolated from peripheral bloods by salting-out method and analyzed by the techniques of PCR-RFLP. Genotype and allele frequencies were calculated and data were analyzed using the χ(2) test. We found a statistically significant difference between the groups with respect to IL-10 genotype distribution (p = 0.001) and allele frequencies (p < 0.0002). However, we did not found any difference between the groups with regarding TGF-ß1 genotype distribution and allele frequencies (p > 0.05). In the combined genotype analysis, IL-10/TGF-ß1 CCCC combine genotype was also estimated risk factor for osteoporosis in Turkish postmenopausal women (p = 0.026). To our knowledge, this is the first report to examine IL-10 gene -597 C > A polymorphism and osteoporosis in Turkish population.

Functional disability of children with spina bifida: its impact on parents' psychological status and family functioning.

OBJECTIVE: To evaluate the impact of functional disability of Turkish children with spina bifida (SB) on parents' psychological status and family functioning. METHODS: Fifty-four children with SB and parents were included. The Functional Measure for Children (WeeFIM), Beck Depression Inventory (BDI), and Family Assessment Device (FAD) were used. RESULTS: Mothers' BDI scores were significantly higher than fathers' (p < 0.001). No significant effects of the knowledge of having children with SB before birth and the number of children in families on BDI scores and FAD sub-scores were found (p > 0.05). According to multiple regression analysis; significant correlations with fathers' BDI were problem-solving (p = 0.012) and general functioning (p = 0.037) and with mothers' BDI was roles (p = 0.018). Only childrens age was found to be an influential variable on WeeFIM scores (p < 0.001). CONCLUSION: Spina bifida healthcare should include psychological support to parents of these children and this support should be independent from disability level of children.

Therapeutic ultrasound versus sham ultrasound for the management of patients with knee osteoarthritis: a randomized double-blind controlled clinical study.

AIM: The aim of this trial was to evaluate the short-term effectiveness of ultrasound (US) therapy on pain, physical function, ambulation activity, disability and psychological status in patients with knee OA. METHODS: Forty-two inpatients with bilateral knee OA were randomized by an independent researcher not involved in the data assessment, to receive either therapeutic continuous US (group 1) or sham US (group 2). A 1-MHz US head was used, set to an intensity of 1 W/cm(2) for 10 min. All patients received 20 min of hot packs, 10 min of interferential current, and 15 min of quadriceps isometric exercise of both knees. Patients in each group received treatments five times weekly for 3 weeks. Patients were evaluated at baseline and at the end of the treatment sessions. Outcome measures included visual analogue scale (VAS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC), 50-m walking speed, Lequesne index, Hospital Anxiety and Depression Scale (HADS). RESULTS: The patients with knee OA had significant improvements in pain, stiffness, functional activity, walking time, disability, depression and anxiety scores with therapeutic US and sham US (P < 0.05). The improvement in pain VAS scores, WOMAC scores, Lequesne index and HADS scores were not significantly different in patients treated with US and sham US (P > 0.05). No side-effects were reported during or after the US treatment periods. CONCLUSION: US therapy is safe but use of US in addition to conventional physical therapy programs seems to have no further significant effect in people with knee OA.

Changes in bone mineral density and bone metabolism markers in premenopausal women with multiple sclerosis and the relationship to clinical variables.

Bone mineral density (BMD) is affected in young adults with multiple sclerosis (MS), which leads to disabling disease. We aimed to show changes that were independent of immobilization by measuring BMD and laboratory markers of bone metabolism in mobile MS patients. We compared a total of 52 premenopausal female patients with relapsing-remitting multiple sclerosis (RRMS) to 41 women of similar age who had no risk factors for osteoporosis. The lumbar and femur BMD were measured using the dual energy X-ray absorptiometry (DXA) method. The urine concentration of serum 25-hydroxycholecalciferol (25-OH vit D(3)), and pyridinoline and deoxypyridinoline were also measured. The concentration of serum osteocalcin was measured to determine the speed of bone metabolism. The mean age of patients (+/- standard deviation [SD]) was 36.1+/-7.4. The average Expanded Disability Status Scale (EDSS) score was 2.2+/-1.8. The concentration of 25-OH vit D(3) and osteocalcin was lower, whereas the concentration of parathyroid hormone (PTH), alkaline phosphatase (ALP), pyridinoline and deoxypyridinoline was higher in the patient group. In the patient group, lumbar 2-4 BMD, T score and Z score and femur neck and trochantor BMD, T score and Z score were significantly lower than in the control group. There was a significant negative relationship between: the disease period and L 2-4 BMD, T score and Z scores; and the femoral neck BMD, T score and Z scores. There was a significant relationship between the total Functional Independence Measure score and the femoral neck, femoral trochanter BMD, T score, and Z score. There was a significant negative relationship between the average EDSS, L 2-4 and all the DXA measurements obtained from the femur. There was a significant relationship between the 25-OH vit D(3) concentration and L 2-4 T score and Z score from the DXA measurements obtained from the femur. There were no significant relationships between osteocalcin, pyridinoline, deoxypyridinoline levels and the BMD measurements. Therefore, the duration of the disease and decrease in functional capacity are the main factors that affect BMD in MS. Apart from the decrease in functional capacity, 25-OH vit D(3) deficiency and secondary PTH increase contribute to the BDM changes observed in MS.

Association of transforming growth factor beta1 gene polymorphism with rheumatoid arthritis in a Turkish population.

OBJECTIVE: Cytokine genes play important roles in the pathogenesis of rheumatoid arthritis (RA). In RA, the plasma and synovial fluid levels of transforming growth factor beta1 (TGFbeta1) have been shown to be raised. The aim of this study was to investigate the relationship between the TGFbeta1 T869C polymorphism and RA in a Turkish population. METHODS: One hundred and thirty-one patients with a clinical diagnosis of RA and 133 healthy controls were enrolled in this study. Analyses of TGFbeta1 T869C gene were made by the polymerase chain reaction-restriction fragment length polymorphism technique. RESULTS: There was no significant difference in genotypic frequency of TGFbeta1 T869C polymorphism between the patients with RA (TT:TC:CC=42.7%:41.2%:16%) and controls (TT:TC:CC=36.1%:48.1%:15.8%) (p=0.48). The age at first occurrence of clinical symptoms of RA did not differ significantly in relation to TGFbeta1 T869C genotypes (p=0.07). Furthermore, there was no significant association between TGFbeta1 T869C genotypes and the presence or absence of radiographic erosions in the patient group (p=0.67). But presence of T allele was associated with 1.92-fold increased risk for RF positivity (p=0.02, OR=1.92, 95% CI=1.08-3.40). CONCLUSION: The allele frequencies for TGFbeta1 T869C polymorphism in RA patients were similar to those in the control group. However, the T allele carriers had 1.92-fold increased risk for RF positivity. Further studies on larger numbers of cases and on the other polymorphic regions of this gene are needed before definite conclusions can be drawn about the role of TGFbeta1 in the etiology of RA.

Effects of two exercise interventions on pulmonary functions in the patients with ankylosing spondylitis.

OBJECTIVE: The aim of this study was to evaluate the impact of two different home-based daily exercise programs on pulmonary functions in the patients with ankylosing spondylitis (AS). METHODS: Fifty-one patients with AS were distributed into three groups. Group 1 (n=19) was given a conventional exercise regimen. Group 2 (n=19) received exercises based on the Global Posture Reeducation (GPR) method. Group 3 (n=13) was accepted as the control group. Patients were assessed according to pain, functional capacity (The Bath Ankylosing Spondylitis Functional Index - BASFI), disease activity (The Bath Ankylosing Spondylitis Disease Activity Index - BASDAI), chest expansion, pulmonary function parameters, and 6-min walk distance (6MWD) test. RESULTS: Although there were significant improvements for BASDAI and BASFI scores in all groups, significant improvements in the VAS pain, chest expansion, pulmonary function parameters and 6MWD test were observed in the exercise groups. The improvements in pain, functional capacity, disease activity, chest expansion, pulmonary function parameters and 6MWD test were better in the exercise groups than in the control group. The GPR method resulted in greater improvements than the conventional exercise program in specific pulmonary function parameters like forced vital capacity, forced expiratory volume in 1s, and peak expiratory flow parameters. CONCLUSION: Both exercises are efficient in improving pulmonary functions. Since the improvements in pulmonary function tests were greater in the patients who performed the exercise according to GPR method, motivated patients should be encouraged to perform this exercise program.

A comparative evaluation of health related quality of life and depression in patients with fibromyalgia syndrome and rheumatoid arthritis.

The aim of this study was to compare health related quality of life (HRQoL) and assess functional and psychological status in rheumatoid arthritis (RA), fibromyalgia syndrome (FS) patients and controls (each 30 subjects). Demographic characteristics, pain and sleep disturbance by Visual Analog Scale, depression by Beck Depression Inventory (BDI), disease impact by fibromyalgia impact questionnaire, DAS-28, and HRQoL by SF-36 were gathered. The FS group scored significantly worser than the RA group with respect to physical role, social functioning and bodily pain subscales of SF-36. The scores of all SF-36 subscales were significantly lower in FS and RA patients than controls except mental health score. All of the subscales of SF-36 were negatively correlated with BDI scores in FS patients. In RA group, the DAS-28 scores were inversely correlated with all of SF-36 subscales. In conclusion, presence of comorbid depression must be taken into account when determining HRQoL in FS and RA. Essentials improving the HRQoL are management of depression in FS and control of disease activity in RA.

Polymorphisms of the serotonin-2A receptor and catechol-O-methyltransferase genes: a study on fibromyalgia susceptibility.

Genetic and environmental factors are thought to play roles in the etiopathology of fibromyalgia syndrome (FMS). The objective of this study was to determine the potential effects of single nucleotide polymorphisms (SNPs) in catechol-O-methyltransferase (COMT) (rs4680) and 5-hydroxytryptamine (serotonin) 2A (5-HT2A) receptor (rs6313 and rs6311) genes on susceptibility to FMS. One hundred seventy-one women (80 FMS, 91 control) were enrolled in the study. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used for the genotyping analyses. Genotype and allele frequencies were calculated by the chi-square test. Beck depression inventory, state and trait anxiety inventory and symptom checklist-90 revised (SCL-90-R) tests were applied to both patients and controls. There were no observed differences in the frequencies of alleles and genotypes between patients and controls for the COMT, and the two 5-HT2A receptor gene polymorphisms (P>0.05). Our results suggest that the investigated polymorphisms seem not to be the susceptibility factors in etiology of FMS.

Serum ghrelin levels but not GH, IGF-1 and IGFBP-3 levels are altered in patients with fibromyalgia syndrome.

INTRODUCTION: Both hypothalamo-pituitary-insulin-like growth factor-1 (IGF-1) axis and ghrelin levels may be altered in fibromyalgia syndrome (FMS) due to increased somatostatin tone. The aim of this study is to compare hypothalamo-pituitary-IGF-1 axis, ghrelin concentrations and their relations in premenopausal women with FMS and premenopausal healthy controls. METHODS: Seventy-five women (47 FMS and 28 healthy women) were enrolled in the study. Fasting plasma glucose, serum growth hormone (GH), insulin, C-peptide, IGF-1, insulin-like growth factor binding protein-3 (IGFBP-3) and ghrelin levels were measured. Depressive symptoms were assessed using beck depression inventory. Pain intensity and sleep disturbance were recorded on a visual analog scale. The activity of daily living was assessed by fibromyalgia impact questionnaire. RESULTS: There were no significant differences in GH, IGF-1, IGFBP-3, glucose, insulin, and C-peptide levels between patients and controls (p>0.05), whereas ghrelin levels were significantly lower in patients than controls (p<0.05). Ghrelin levels were not correlated with GH, IGF-1, IGFBP-3, glucose, insulin, and C-peptide levels while they were positively correlated with tender point score and sleep disturbance score and negatively correlated with pain intensity score. CONCLUSION: Our results suggest that low levels of ghrelin in FMS are not related to the changes in hypothalamo-pituitary-IGF-1 axis but may be related to some symptoms of FMS. Our results need to be clarified by further studies.

Evaluation of hand functions in hemodialysis patients.

BACKGROUND AND AIMS: Patients with end stage renal disease (ESRD) have many musculoskeletal abnormalities, including hand dysfunction. The Sollerman test evaluates hand grip function in daily activities. The relationships between Sollerman test (dominant hand) with Duruoz's Hand Index (DHI), Health Assessment Questionnaire (HAQ), and Beck Depression Inventory (BDI) tests have not been investigated previously. The aims of this study are to evaluate hand grip function using the Sollerman test in hemodialysis (HD) patients, correlate this test with other measures evaluating hand function or psychosocial status, and investigate factors that can affect Sollerman test. METHODS: One-hundred twenty HD patients (64 male, 56 female, mean age 51 +/- 1.4 years, mean duration of HD therapy 5.3 +/- 3.7 years) were included in this study. The HAQ, DHI, and BDI scores were determined by standard techniques. All patients underwent the Jamar grip test and Sollerman test for the dominant (D) and non-dominant hand (ND). RESULTS: We found a positive correlation between Sollerman test (dominant hand) with Sollerman test-ND, Jamar-D, and Jamar-ND tests. There were negative correlations between Sollerman test with age, HAQ, BDI, and DHI tests. CONCLUSIONS: The relationships between Sollerman test (dominant hand) with DHI, HAQ, and BDI tests have not been investigated previously. This study showed the correlations between the Sollerman test (dominant hand) and other tests (either positive or negative). Psychosocial problems can affect hand functions.
