Validity and Reliability of the Turkish Version of Mandibular Function Impairment Questionnaire.

OBJECTIVE: To assess the validity and reliability of the Turkish version of the Mandibular Function Impairment Questionnaire (MFIQ-TR). METHODS: Included in this study were 248 patients diagnosed with temporomandibular disorder (TMD) according to Diagnostic Criteria for TMD Axis I protocol. Construct-related validity was evaluated through internal and external construct validity; convergent and divergent validities were evaluated by the average variance extracted (AVE), composite reliability (CR), and bivariate correlations between factors. Reliability was assessed by internal consistency and test-retest reliability. RESULTS: All items of the MFIQ-TR had content validity and factor loadings above 0.5. The model statistics indicated a good fit. The convergent validity was very good (AVE > 0.5 and CR > 0.7), and the discriminant validity was satisfied. Internal consistency and test-retest reliability of the MFIQ-TR were excellent. CONCLUSION: The MFIQ-TR is a valid and reliable instrument for evaluating the impairment of mandibular function in Turkish patients with TMD.

A comparison of the effectiveness of splinting, exercise and electrotherapy in women patients with hallux valgus: A randomized clinical trial.

BACKGROUND: Hallux valgus (HV) is a very common foot deformity involving lateral deviation of the hallux and medial deviation of the first metatarsal head. OBJECTIVES: To investigate the effects of HV night splinting, exercise and electrotherapy on the HV angle, and foot-specific health-related quality of life. METHODS: Sixty women (120 feet) with bilateral HV deformity were randomly assigned to one of three groups - an HV night splint (SP) group, an exercise (EX) group, and a high-voltage galvanic stimulation (HVPGS) (EL) group. The patients in SP group used the HV night splints while resting or sleeping for at least 8 h a day and the patients in the EX group performed exercises 3-4 times a day with 10 repetitions for the duration of the one-month treatment period. Twenty-minute HVPGS was applied in total over three weekly sessions for four weeks in EL group. Angular degrees (hallux interphalangeal angle (HIPA), HV angle (HVA), and intermetatarsal angle (IMA)) were determined before (t0) and three months after treatment (t2). Foot-specific quality of life was assessed using the Manchester-Oxford Foot Questionnaire (MOFQ) at t0, after one month (t1), and at t2. RESULTS: All groups exhibited significant changes in the HIPA, HVA, and IMA angles and outcome measures (p ≤ 0.001). Decreases in the HIPA and IMA angles, and MOFQ-Pain subscale scores, were higher in the SP group than in the other two groups (p < 0.05). IMA angle at t2, MOFQ-Walking score at t1 and t2 and MOFQ-Pain subscale score at t1 were lower in the SP group (p < 0.05). CONCLUSION: The SP group exhibited more positive effects in the parameters measured than the other two groups. A combination of these conservative treatment approaches may be more beneficial to improve HV symptoms with longer follow-up periods. CLINICALTRIALS. GOV IDENTIFIER: NCT04393545.

Developing a shoulder pain scale for wheelchair basketball players.

BACKGROUND: Shoulder pain in wheelchair (WC) basketball players is common. Yet there was no scale to define shoulder pain. OBJECTIVE: This study was performed to develop a shoulder pain scale for WC basketball players. METHODS: A five-step procedure was followed: Identifying the feature, writing down the items and drafting the form, formulating the final form, pre-pilot-pilot implementation, and validity-reliability analyses. The final form of the scale consisted of 15 items about self-care and sport-specific activities. RESULTS: External factor analysis showed that the scale had a two-factor structure which is "Shoulder Pain during Sports" and "Shoulder Pain during Self-care Activities". Pre-rotation results of factor analysis showed that if all of the items were loaded on the first factor, it would have an eigenvalue more than 7 times larger than the eigenvalue of the second factor. Therefore, it can be concluded that the scale can be used as a one-dimensional scale. The Cronbach's Alpha values were found to be 0.94 and 0.92 for the shoulder pain factor during sports and self-care activities, respectively. Total value was found to be 0.95. The corrected item-total correlation values were all above 0.60. CONCLUSIONS: This newly developed valid, reliable scale allows assessment of the shoulder pain of WC basketball players.
