Adaptação e validação intercultural da versão portuguesa do Physical Therapy Outpatient Satisfaction Survey

ABSTRACT - The aim of this study was to adapt and validate the Physical Therapy Outpatient Satisfaction Survey (PTOPS) for the Portuguese culture. This version was obtained by a forward/ backward translation, consensus panels, and pre-test. The Portuguese PTOPS was administered to 76 physical therapy outpatients in 10 health services. The content analysis (panels of experts and lay people) and the factor analysis resulted in a reduction of the original 34 items to 28 items that validly identify 3 constructs. The reliability was acceptable for both internal consistency (Cronbach’s alpha = 0.73) and reproducibility (ICC between 0.84 and 0.87), which represent acceptable levels of validity and reliability.RESUMO - Foi objetivo deste estudo adaptar e validar para a cultura portuguesa o Physical Therapy Outpatient Satisfaction Survey (PTOPS).

Reliability and validity of PedsQL for Portuguese children aged 5–7 and 8–12 years

BACKGROUND: Pediatric Quality of Life Inventory (PedsQL) is a measure to assess health-related quality of life (HRQoL) in children and adolescents. It is formed by 23 items adapted to children age and includes a parent proxy report version. With four multidimensional subscales and three summary scores, it measures health as defined by WHO. The concepts measured by this instrument are ‘physical functioning’ (8 items), ‘emotional functioning’ (5 items), ‘social functioning’ (5 items) and ‘school functioning’ (5 items). It also measures a ‘total scale score’ (23 items), a ‘physical health summary score’ (8 items) and a ‘psychosocial health summary score’ (15 items). The aim of this paper is to present the main results of the cultural adaptation and validation of the PedsQL into European Portuguese. METHODS: The Portuguese version was the result of a forward-backward translation process, with a cognitive debriefing analysis, guaranteeing face validity and semantic equivalence. Children aged 5–7 and 8–12 were randomly selected and were asked to fill a socio-demographic data survey and the Portuguese versions of PedsQL and KINDL, another HRQoL measure for children and adolescents. They were divided into three groups, healthy children, children with type I diabetes and children with spina bifida. The reliability was tested for reproducibility (ICC) and internal consistency (Cronbach’s alpha). The construct validity (known-groups discriminant validity) was supported by differences between self-reports from healthy children and children with chronic conditions, and from children with chronic diseases and their parents. The criterion validity was tested after the correlations of the scores obtained by both children and adolescents HRQoL assessment instruments. RESULTS: A total of 179 children and 97 parents were recruited. PedsQL demonstrated good levels of reproducibility (r > 0.95 in all versions) and acceptable levels of internal consistency with Cronbach’s alpha at 0.70 on most scales. Concordance values between children’s and parents’ perceptions ranged between 0.36 and 0.78 and the correlations with KINDL questionnaire were excellent, supporting concurrent validity. CONCLUSIONS: The Portuguese version of the PedsQL demonstrated acceptable psychometric properties for future research and clinical practice for children aged 5–12

Cross-cultural adaptation and validation of the Portuguese Survey of musculoskeletal conditions, playing characteristics and warm-up patterns of golfers

BACKGROUND: The University of Western Ontario Questionnaire for Musculoskeletal Conditions in Senior Golfers (MSK Golfers) was developed in Canada because of a lack of knowledge concerning musculoskeletal conditions directly related to golf play and warm-up, although the high injury incidence in golf practice. This lack of epidemiological measures also exists for the Portuguese golf population. OBJECTIVE: The purpose of this study was to translate and cross-culturally adapt the MSK Golfers questionnaire into Portuguese and to test its construct validity and reproducibility. METHODS: The MSK Golfers was translated from English to Portuguese and tested for psychometric properties. Sixty-one golfers, aged between 14 and 70 years and with at least 1 year of practice in golf, were recruited. The validity of the MSK Golfers was assessed by evaluating data quality (missing, floor and ceiling effects). Reproducibility analysis included intra-class correlation coefficients (ICC) (2,1) and Cohen's Kappa coefficient. RESULTS: The ICC values for continuous items ranged from 0.634 to 0.998 with the exception of one item on golf activity. Kappa statistics for the categorical items ranged between 0.714 and 1.00. CONCLUSIONS: The Portuguese version of the MSK Golfers, including playing characteristics and warm-up patterns of golfers, showed a high reliability for a golfing population with an age range of 14 to 70 years

Electromyographic analysis of posterior deltoid, posterior rotator cuff and trapezius musculature in different shoulder exercises

Background: The shoulder external rotator muscles and the different portions of the trapezius muscle have never been studied in exclusivity. However, the literature has provided several exercises which have been used in this study. Purpose: To quantify electromyographic activity of the shoulder external rotator muscles and the upper, middle and lower trapezius in seven exercises. Methods: 20 healthy males performed 7 exercises in random order. Surface electromyography was recorded for the posterior deltoid, infraspinatus, teres minor, upper, middle and lower trapezius. Results: The four prone exercises presented the highest levels of EMG activation in the External Rotators Synergy (the average activation of arm external rotator muscles group) and in the Trapezius Synergy (the average activation of the three portions of trapezius). The infraspinatus muscle obtained the highest activation values in exercises 1 (prone horizontal abduction at 90° with full external rotation, thumb up ), 4 (prone external rotation at 90º abduction and elbow at 90º), and 5 (side-lying ER with elbow on the trunk). The highest activation level of the teres minor muscle was found in Exercise 1. Conclusions: The four prone exercises demonstrated the highest EMG activity in the shoulder, considering both the external rotator muscles and the trapezius. However, if the focus of the strength training process is mainly to strengthen the two external rotator muscles of the rotator cuff, with an adequate intramuscular coordination pattern for the trapezius, the side lying ER with the elbow resting on the trunk seems to be the most appropriate exercise

Emg Activation Of Abdominal Muscles In The Crunch Exercise Performed With Different External Loads.

The aim of this study was to describe by means of surface electromyography the activation of the rectus abdominis, obliquus externus and rectus femoris muscles during the crunch abdominal exercise performed with loads. Thirteen subjects performed crunch exercises with loads representing 80, 60, 40 and 20% of the 1-RM (100%) in a random order with the subjects drawing lots, and with a 5 min rest between sets. Surface bipolar EMG electrodes were used. The root mean square of the EMG was calculated for the first repetition of each load. Differences between conditions were tested using a one way ANOVA for repeated measures. Post-hoc Bonferroni tests was used to detect significant differences between specific loads (p<0.05). An average of the percentage values of all studied abdominal muscles was used as a representative value of abdominal synergy (Ab Syn). In general it can be concluded that the abdominal muscles were significantly more recruited in the 100% load condition. Abdominal activation significantly differed between the various loads; however, in general adjacent loads (20 vs. 40% - 1-RM) did not differ. These results suggest that for young, healthy and physically active adults when the objective is progression in the training process of abdominal force, the option ought to be for changes of load superior to 20% of the 1-RM.1057-6

Influence of short-term unweighing and reloading on running kinetics and muscle activity

International audienceIn running, body weight reduction is reported to result in decreased lower limb muscle activity with no change in the global activation pattern (Liebenberg et al. in J Sports Sci 29:207-214). Our study examined the acute effects on running mechanics and lower limb muscle activity of short-term unweighing and reloading conditions while running on a treadmill with a lower body positive pressure (LBPP) device. Eleven healthy males performed two randomized running series of 9 min at preferred speed. Each series included three successive running conditions of 3 min [at 100 % body weight (BW), 60 or 80 % BW, and 100 % BW]. Vertical ground reaction force and center of mass accelerations were analyzed together with surface EMG activity recorded from six major muscles of the left lower limb for the first and last 30 s of each running condition. Effort sensation and mean heart rate were also recorded. In both running series, the unloaded running pattern was characterized by a lower step frequency (due to increased flight time with no change in contact time), lower impact and active force peaks, and also by reduced loading rate and push-off impulse. Amplitude of muscle activity overall decreased, but pre-contact and braking phase extensor muscle activity did not change, whereas it was reduced during the subsequent push-off phase. The combined neuro-mechanical changes suggest that LBPP technology provides runners with an efficient support during the stride. The after-effects recorded after reloading highlight the fact that 3 min of unweighing may be sufficient for updating the running pattern
