The efficacy of balance and proprioception exercises in female patients with knee osteoarthritis: A randomized controlled study.

OBJECTIVE: Loss of proprioception and balance disorders are commonly observed in patients with knee osteoarthritis. In this study, we aimed to investigate the effects of balance and proprioception exercises in patients with knee osteoarthritis. DESIGN: A single-center randomized trial with three parallel arms. SETTING: A tertiary health care facility in Turkey. PARTICIPANTS: Female patients with knee osteoarthritis aged 40-70 years. INTERVENTIONS: Ten-week exercise program in Biodex training, classical balance training and isometric strengthening groups. MAIN MEASURES: Dynamic balance (overall stability index and the modified Clinical Test of Sensory Interaction and Balance), pain (visual analogue scale), physical function (30-s chair stand test and 40-meter fast-paced walk test) and quality of life (Knee Injury and Osteoarthritis Outcome Score). RESULTS: Eighty-nine patients enrolled in the study. The Biodex training group, the classical training group, and the control group had overall stability index values of 1.0 ± 0.07, 1.4 ± 0.07 and 1.4 ± 0.07, and the Modified Clinical Test of Sensory Interaction and Balance - Condition-3 values of 0.7 ± 0.04, 0.9 ± 0.04 and 0.9 ± 0.04 respectively, at the end of treatment. In terms of pain scores on movement, each group showed significant improvement compared to their baseline, and the classical balance training group had better scores than the control group. No other significant difference was found between the groups. Physical function and quality of life outcomes showed significant main effects only in the time factor. CONCLUSIONS: Balance and proprioception exercises may have positive effects on dynamic balance and pain. The effects on physical function and quality of life should be investigated in further studies with larger sample.

Is the left/right judgment task performance altered in unilateral carpal tunnel syndrome: And associated with symptom severity?

BACKGROUND: Left/right judgment task performance (LRJT) is impaired in severe neuropathic pain conditions. However, comparison of LRJT performance in patients with carpal tunnel syndrome (CTS) with a control group with similar cognitive functions has not been investigated. OBJECTIVE: The aim of the study was to compare the LRJT performance of CTS patients with healthy controls and the unaffected side. METHODS: Seventy-five CTS patients with dominant, right-hand involvement and 75 control subjects were included in the study. The Recognize® tablet application was used for LRJT performance. Tactile acuity (Two-point discrimination) and handgrip strength; pain severity (Visual Analog Scale) and neuropathic component of pain (Pain Detect Questionnaire); symptom severity and functional impact of CTS (Boston CTS Assessment Test) were evaluated. Mixed-design ANOVAs and correlation analyses were used for data analysis. DESIGN: Cross-sectional study. RESULTS: Analysis of variance showed that there was no significant effect of side (affected versus unaffected) or group (CTS versus control group) on recognition accuracy or time. Significant group*site interactions were found for the two-point discrimination F (1,148) = 6.388, p = 0.013; and for handgrip strength F (1,148) = 17.552, p < 0.01. A statistically significant negative correlation was found between recognition accuracy and symptom duration and a significant positive correlation was found between recognition accuracy and handgrip strength in CTS patients (r = -0.267, p = 0.020; r = 0.290, p = 0.012). CONCLUSION: CTS patients recognize the affected side as accurately and quickly as the unaffected side and control group. Further research is needed to clarify the relationship between LRJT performance in the severely affected CTS group. GOV REGISTRATION NUMBER: NCT04967144 CLINICALTRIALS.

Impact of peer-led group education on the quality of life in patients with ankylosing spondylitis.

OBJECTIVES: To determine the effect of peer-led group education on the quality of life and depression in patients with ankylosing spondylitis (AS). METHODS: Eighty patients with definite AS were allocated randomly to either the education or control group. The education group (n = 40) was subjected to a peer-led group education program about disease and was given an educational booklet, while the control group (n = 40) was given the educational booklet only. Levels of quality of life and depression were measured at baseline, immediately after education (fourth week) and at 6 months in both groups. RESULTS: The results are based on 56 (n = 27, education group; n = 29, control group) patients. The level of quality of life and depressive symptoms were not changed except for a deterioration in the social functioning subgroup of Short From (SF)-36 in both groups. When the groups were compared, there were no significant differences between changes in social functioning scores. CONCLUSIONS: Peer-led education did not alter quality of life levels and depression scores. However, because of the maintainance of quality of life levels, this type of intervention may be considered as a supplementary intervention to the standard medical care for management of AS.

Comparison of the DAS28-CRP and DAS28-ESR in patients with rheumatoid arthritis.

AIM: To compare the Disease Activity Score with 28 joint (DAS28) using erythrocyte sedimentation rate (ESR) (DAS28-ESR) and DAS28 using C-reactive protein (CRP) (DAS28-CRP) with thresholds validated for DAS28-ESR in Turkish patients with rheumatoid arthritis. METHOD: The DAS28 data of 112 patients with rheumatoid arthritis followed in a local outpatient clinic were used. First, the correlation between DAS28-CRP and DAS28-ESR and the correlation between their unique components ([0.36 × In (CRP + 1) + 0.96] and [0.70 × In (ESR)]) were analyzed. Second, a Bland-Altman plot was constructed for the evaluation of the level of agreement between DAS28-CRP and DAS28-ESR. Lastly, the agreement between these two methods was analyzed by κ coefficient. RESULTS: Although there was a strong correlation between DAS28-CRP and DAS28-ESR, the correlation between their unique components was fair. Although more than 95% of the point data fall between the upper and lower bounds of the limit of agreement, the percentage error (46%) was higher than the acceptable proportion of 30%. The κ coefficient of agreement between DAS28- ESR and DAS28-CRP with validated thresholds for DAS28-ESR was 0.42, which was close to the lower boundary for moderate agreement. CONCLUSION: The results of this study demonstrated that there is discordance between DAS28-ESR and DAS28-CRP with the validated thresholds for DAS28-ESR. Using the DAS28-CRP with threshold values validated for DAS28-ESR may lead to errors in the determination of disease activity and therefore may lead to errors in the management of patients with rheumatoid arthritis.

Effects of home-based exercise program on the functional status and the quality of life in patients with rheumatoid arthritis: 1-year follow-up study.

We previously reported the efficacy of a 4-week home-based exercise therapy for patients with rheumatoid arthritis (RA). In this study, we aimed to investigate whether short-term improvements in the functional status and quality of life were maintained at 1 year. Patients who completed 4-week home-based exercise program were advised to maintain the same exercises for 1 year duration. Changes of functional status and quality of life in patients with RA were evaluated by the Health Assessment Questionnaire (HAQ) and the Rheumatoid Arthritis Quality of Life Scale (RAQoL). The change of the variables at the different time points (baseline, 4 weeks, and 1 year) was assessed by the repeated measure of ANOVA test with Geisser-Greenhouse correction. Pairwise ANOVA comparisons adjusted using the Bonferroni correction were conducted. Twenty-eight (63.6%) of 44 patients were available for follow-up at 1 year. The results of repeated measure ANOVA showed that there was a statistically significant difference between three assessments in the HAQ (P = 0.015) and RAQoL (P = 0.037) scores at the end of the follow-up. Improvements in the functional status and health-related quality of life at 4 weeks were maintained at 1-year follow-up. In conclusion, we observed significant improvements in the functional status and health-related quality of life by 4-week home-based exercise program. Furthermore, these improvements were maintained at 1-year follow-up. Further studies are needed to confirm the usefulness of the home-based exercise therapy.

Foot deformities in patients with rheumatoid arthritis: the relationship with foot functions.

AIM: The aim of this study was to investigate foot deformities in patients with rheumatoid arthritis (RA), to detect frequency of deformities and to assess the relationship between foot deformities and foot functions. METHODS: Anteroposterior and lateral radiographs of 40 patients and 40 control subjects were studied. The hallux valgus (HV) angle, intermetatarsal angle between first and second metatarsals, intermetatarsal angle between first and fifth metatarsals, and calcaneal pitch were measured on radiographs. Foot functions were measured by the Foot and Ankle Outcome Score (FAOS). RESULTS: The frequency of foot deformities in RA patients was determined as 78.8%. The most frequent foot deformity in RA patients was HV (62.5%), followed by metatarsus primus varus (MPV) (41.3%). MPV and splaying of the forefoot deformities were significantly more frequent in RA patients than the control group (P < 0.05). Mild to moderate effect on FAOS subscales was observed in RA patients. There was a slight, but significant correlation between the foot deformities and the FAOS subscales except for quality of life subscale. CONCLUSIONS: In this study, it has been shown that foot deformities are frequent in patients with RA and that there is slight deterioration in foot functions related to RA. Our results indicated that foot deformities have small, but clinically important changes on foot functions. There is a need for more studies, which evaluates the foot deformities, to further explore the relationship between the foot deformities and foot function in patients with RA.

Fatigue in patients with ankylosing spondylitis: relationships with disease-specific variables, depression, and sleep disturbance.

This study was designed to evaluate (a) the frequency of fatigue and its multi-dimensional nature, and (b) its association with demographic variables, disease-specific variables, and other variables, covering depression and sleep disturbance in patients with ankylosing spondylitis (AS). Sixty-two patients with AS were included in the study. Fatigue was assessed by the fatigue item of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF). While the disease activity was evaluated by the BASDAI, the functional state was assessed by Bath Ankylosing Spondylitis Functional Index, metrological measurements by Bath Ankylosing Spondylitis Metrology Index, global well-being by Bath Ankylosing Spondylitis Global Score, the pain on rest by VAS (0-10 cm), sleep disturbance by Pittsburgh Sleep Quality Index, and depressive symptoms by Zung Self-Rating Depression Scale. Fifty percent of the patients had severe fatigue. Multi-dimensional assessment with MFSI-SF enabled us to identify fatigue in more detail. The disease-specific variables, covering pain, stiffness, disease activity, and physical functioning, contributed significantly with both BASDAI fatigue and MFSI-SF as dependent variables, accounting for 61.3% and 44.7% of the variance, respectively. Disease activity was the most powerful predictor of both single-dimensioned and multi-dimensioned fatigue. It was also found that the contribution of depression on fatigue was 12%. In conclusion, it was observed that half of the patients had severe fatigue, and multi-dimensional assessment was provided to understand specific aspects of fatigue better. Even though disease activity had a considerable effect on fatigue, the effects of psychogenic factors, especially depression, should be taken into consideration in the management of AS.
