The relation of hand functions with radiological damage and disease activity in rheumatoid arthritis

The purpose of this study was to investigate specifically the correlation of hand functions determined by Duruoz hand index (DHI) with radiological findings and disease activity in rheumatoid arthritis (RA) patients. Forty-eight RA patients were evaluated with DHI questionnaire, disease activity score (DAS) 28 and modified Larsen scoring method. Correlation between DAS-28 and DHI was assessed in all the patients. Mean DHI scores were compared between patients in remission (DAS-28 < 2.6) and patients who have more or less disease activity (DAS-28 >or= 2.6). To exclude the probable conflicting effect of disease activity on hand functions, the correlation between radiological scores and DHI was investigated only in patients with remission. There was a positive correlation between DAS-28 and DHI in all patients group (r = 0.434, P < 0.002). No correlation between the radiological scores of any joint groups and DHI could be found in patients with remission. Hand functions seemed to be affected prominently from disease activity. Radiological scores demonstrating joint damage were not in relation with hand functions.

Sezer N, Yavuzer G, Sivrioglu K, Basaran P, Koseoglu BF. Clinimetric properties of the Duruoz Hand Index in patients with stroke. Objective To investigate the reliability, validity, and responsiveness of the Duruoz Hand Index (DHI) in assessing activity limitation related to hand function in patients with stroke. Design Prospective validation study. A consecutive sample of stroke patients was evaluated on 3 occasions: 2 baseline measurements with a 24-hour interval in between, and again 1 month later immediately after a 4-week inpatient rehabilitation program. Setting Three different inpatient rehabilitation centers. Participants A consecutive sample of 56 patients with stroke (33 men, 23 women) with a mean age 62 years and a mean time since stroke 84 days. Interventions Not applicable. Main Outcome Measures Brunnstrom stages, Modified Ashworth Scale, sensory status, FIM instrument, and DHI. Test-retest reliability was tested using the intraclass correlation coefficient (ICC) and internal consistency was tested using the Cronbach α coefficient. Indexes of measurement error were calculated by standard error of measurement and minimal detectable change (MDC). Construct validity was assessed by association with the FIM instrument (Spearman ρ correlation coefficient). Responsiveness was assessed by calculation of the effect size and paired t test. Results The test-retest reliability and internal consistency of the DHI were excellent, with an ICC of .99 (95% confidence interval, .93−.99) and α of .97. The MDC was 1.4 DHI points. The correlation between the DHI and the FIM self-care items was high (ρ=−.73). The DHI significantly discriminated the patients with dominant side paresis versus nondominant side paresis ( P<.01). The DHI score improved significantly after a 4-week inpatient rehabilitation program ( P<.05). Conclusions The DHI is a time and labor efficient, practical instrument that can be used to assess the hand-related activity level for clinical and research purposes in patients with stroke.

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.

The effects of the diabetes related soft tissue hand lesions and the reduced hand strength on functional disability of hand in type 2 diabetic patients

Objectives The aim of the present study is to examine the effects of diabetes related soft tissue hand lesions such as Dupuytren's disease, trigger finger and limited joint mobility (LJM) and the reduced hand strength on the functional disability of the hand in type 2 diabetic patients. Methods Forty-four type 2 diabetic patients and 60 age and sex matched controls were included in the study. Subjects were examined for the presence of Dupuytren's disease, trigger finger and LJM. Grip strength was tested first with Jamar dynamometer followed by pinch strength measurements using by a manual pinchmeter. Electrophysiological studies were performed in both groups. Duruöz Hand Index (DHI) was used to assess the functional hand disability. Results The mean DHI score of the diabetics was significantly higher than controls ( p < 0.0001). Dupuytren's disease, trigger finger or LJM was not correlated with DHI in diabetic patients ( p > 0.05). The grip and pinch strengths were significantly lower in diabetic patients than the non-diabetic controls ( p < 0.05) and the grip and pinch strengths were negatively correlated with DHI in type 2 diabetic patients ( p < 0.001). Conclusion Dupuytren's disease, trigger finger and LJM did not cause to functional disability of hand but low hand strength was found to cause functional disability of hand in our type 2 diabetic patients.

Reliability and Validity of a Self-report of Hand Function in Persons with Rheumatoid Arthritis

The purpose of this study was to examine the test–retest reliability and the concurrent validity of the Duruöz Hand Index (DHI) in persons with rheumatoid arthritis (RA). Forty participants with RA and no other major medical problems completed the DHI, a self-report of hand function, at two points in time to assess test–retest reliability. To determine concurrent validity, participants were also administered three performance-based tests, the Arthritis Hand Function Test (AHFT), the Hand Mobility in Scleroderma Test (HAMIS), and the Keitel Functional Test (KFT), and two self-report questionnaires of functional ability, the Health Assessment Questionnaire (HAQ) and the Scleroderma Functional Assessment Questionnaire (SFAQ). Test–retest reliability intraclass correlation coefficients for the DHI ranged from 0.83 to 0.90. Scores on the DHI were significantly correlated with scores on the AHFT ( r s = 0.36–0.54), the HAMIS ( r s = 0.39), the HAQ ( r s = 0.78), the HAMIS ( r s = 0.39), and the SFAQ ( r s = 0.85). Scores on the DHI did not correlate with KFT scores. The results from this study show the DHI to be a reliable and valid test for hand function in persons with RA.

Reliability and validity of the Duruoz Hand Index in persons with systemic sclerosis (scleroderma).

To examine the test-retest reliability and concurrent validity of the Duruoz Hand Index (DHI) in persons with scleroderma. Forty patients with scleroderma and no other major medical problems completed the DHI at 2 points in time to assess test-retest reliability. To assess validity, participants were administered the Arthritis Hand Function Test (AHFT), the Hand Mobility in Scleroderma Test (HAMIS), and the Keital Function Test (KFT), all performance-based tests. In addition, participants completed the Health Assessment Questionnaire (HAQ), a self report of functional ability. Test-retest reliability intraclass correlation coefficients for the DHI ranged from 0.81 to 0.97. Scores on the DHI did not correlate with HAMIS scores, but were significantly correlated with scores from the KFT (rs = 0.48, P < 0.01), HAQ (rs = 0.79, P < 0.01), and all sections of the AHFT (rs = 0.34-0.60, P < 0.05-0.01). The results from this study show the DHI to be a reliable and valid test for persons with scleroderma.
