Reliability and Validity of the Avoidance of Daily Activities Photo Scale for Patients With Shoulder Pain (ADAP Shoulder Scale).

OBJECTIVE: The Avoidance of Daily Activities Photo Scale for Patients With Shoulder Pain (ADAP Shoulder Scale) was developed to assess pain-related avoidance behavior during daily activities in people with shoulder pain. However, its measurement properties must be verified according to international guidelines. As such, this study investigated the following 4 measurement properties of the ADAP Shoulder Scale: reliability, measurement errors, convergent validity, and floor and ceiling effects. METHODS: The sample comprised 100 individuals with chronic shoulder pain (43 men and 57 women; mean duration of symptoms of 29.7 [SD = 89.0] months; mean age of 44.9 [SD = 15.9] years). The mean test-retest reliability range was 5 days via the intraclass correlation coefficient (ICC). Measurement errors included the standard error of measurement and the minimal detectable change. Convergent validity was analyzed by applying the Pearson correlation with the Tampa Scale for Kinesiophobia, Pain Catastrophizing Scale, and Shoulder Pain and Disability Index. RESULTS: The ADAP Shoulder Scale showed excellent test-retest reliability, both in all domains and in the total score [ICC(2,1) = 0.94; 95% CI = 0.92-0.96]. The standard errors of measurement for the free-movement, high-effort, and self-care domains were 8.1%, 6.0%, and 7.6%, respectively. The minimal detectable change for the total score of the ADAP Shoulder Scale was 16.0%. The total score of the ADAP Shoulder Scale was low to moderately correlated with the total scores of the Tampa Scale for Kinesiophobia (r = 0.52), Pain Catastrophizing Scale (r = 0.30), and Shoulder Pain and Disability Index (r = 0.72). No floor or ceiling effects were detected in the total score. CONCLUSION: The ADAP Shoulder Scale is a reliable, valid instrument for assessing avoidance behavior in adults who have chronic shoulder pain and are not athletes. IMPACT: This study provides evidence that the ADAP Shoulder Scale is appropriate for clinical and practical use in people with chronic shoulder pain.

Development of the Avoidance Daily Activities Photo Scale for Patients With Shoulder Pain.

OBJECTIVES: The purpose of this study was to develop the Avoidance of Daily Activities Photo Scale (ADAP Shoulder Scale) to measure shoulder pain-related avoidance behavior in patients with shoulder pain and evaluate and report the structural validity and internal consistency of the scale. METHODS: Potential daily activities involving the shoulder were selected from the activities and participation domain of the International Classification of Functioning, Disability and Health. The selected activities were presented to an expert panel, health care professionals, and patients with shoulder pain with the question "How much do you think it is important to ask patients with shoulder pain about this activity?" Activities attaining a content validity index (CVI) ≥ 0.8 were represented using a digitally colored photograph. Activity photographs were evaluated by health care professionals and patients with shoulder pain. Photographs with a CVI ≥ 0.8 were included in the scale. To evaluate structural validity and internal consistency of the scale, exploratory factor analysis was performed to determine the presence of any scale domain. Cronbach alpha was calculated to indicate the internal consistency of each domain. RESULTS: Of the 107 preselected activities, 21 attained a CVI ≥ 0.8. Eighteen photographs (CVI ≥ 0.8) were included in the scale after being analyzed by 120 health care professionals and 50 patients with shoulder pain. Exploratory factor analysis (N = 156) showed that the ADAP Shoulder Scale consists of 3 domains: free movement, high effort, and self-care. The internal consistencies of the domains were 0.92, 0.89, and 0.92, respectively. CONCLUSION: The ADAP Shoulder Scale included 15 photographs distributed in 3 domains. All domains had a high internal consistency. The scale is easily applicable, well understood, and relevant for shoulder pain. IMPACT: The ADAP Shoulder Scale can be used to rate shoulder pain-related avoidance behaviors.

Concurrent validity of handheld dynamometer measurements for scapular protraction strength.

BACKGROUND: Handheld dynamometers (HHD) provide quick and low-cost assessments of muscle strength and their use has been increasing in clinical practice. There is no available data related to the validity of HHD for this measurement. OBJECTIVE: To verify the concurrent validity of scapular protraction measurements using an HHD. METHODS: Individuals with traumatic anterior glenohumeral instability were allocated in Instability Group (n=20), healthy swimmers were allocated in Athletes Group (n=19) and healthy subjects were allocated in Sedentary Group (n=21). Concurrent validity was verified by the Pearson correlation test between HHD and isokinetic measurements. The agreement between instruments was verified by Bland-Altman plots, for each of the two HHD positions. RESULTS: A moderate correlation was observed between seated (r=0.59) and lying supine HHD (r=0.54) and isokinetic dynamometer measurements for the all groups. Separated group analysis exhibited a strong correlation between seated HHD and isokinetic dynamometer measurements in the Instability Group (r=0.80), Sedentary Group (r=0.79) and Athletes Group (r=0.76). The Bland-Altman plot showed greater agreement in the seated position than the lying supine position when comparing measurements with the HHD and isokinetic in both the general sample and separated groups. CONCLUSION: The HHD may be considered a valid tool for assessing scapular protraction muscle strength among healthy athletes, non-athletes and subjects with shoulder instability. We recommend to assess subjects in the seated position and to be aware that the HHD tends to overestimate the peak force, compared with the gold-standard isokinetic dynamometer.

Scapular muscles weakness in subjects with traumatic anterior glenohumeral instability.

OBJECTIVE: To investigate possible alterations on scapular muscle strength in subjects with traumatic anterior glenohumeral instability. DESIGN: Cross-sectional study. SETTING: Laboratory setting. PARTICIPANTS: Fifty-two subjects of both sexes: 26 healthy and 26 with traumatic anterior glenohumeral instability. MAIN OUTCOME MEASURES: Subjects performed maximal isometric and concentric isokinetic contractions of shoulder protraction and retraction in scapular and sagittal planes, at slow (12.2 cm/s) and fast (36.6 cm/s) speeds. RESULTS: Subjects with glenohumeral instability presented lower peak force of protraction and retraction during isometric and fast speed tests in the scapular plane; and of isometric protraction in the sagittal plane. CONCLUSIONS: People with traumatic anterior glenohumeral instability present muscle weakness of scapular protractors and retractors. Considering the importance of the scapulothoracic muscles for the dynamic stability of the glenohumeral joint, strengthening of these muscles is recommended for rehabilitation of traumatic anterior glenohumeral instability.

Glenohumeral interposition of rotator cuff stumps: a rare complication of traumatic rotator cuff tear.

The present report describes a case where typical findings of traumatic glenohumeral interposition of rotator cuff stumps were surgically confirmed. This condition is a rare complication of shoulder trauma. Generally, it occurs in high-energy trauma, frequently in association with glenohumeral joint dislocation. Radiography demonstrated increased joint space, internal rotation of the humerus and coracoid process fracture. In addition to the mentioned findings, magnetic resonance imaging showed massive rotator cuff tear with interposition of the supraspinatus, infraspinatus and subscapularis stumps within the glenohumeral joint. Surgical treatment was performed confirming the injury and the rotator cuff stumps interposition. It is important that radiologists and orthopedic surgeons become familiar with this entity which, because of its rarity, might be neglected in cases of shoulder trauma.

O objetivo deste trabalho é relatar um caso com os achados de imagem característicos da lesão traumática do manguito rotador com interposição de múltiplos cotos de tendões do manguito rotador entre a glenoide e o úmero, confirmada cirurgicamente. Esta condição é uma rara complicação do trauma do ombro. Em geral ocorre no trauma de alta energia, frequentemente associada com luxação da articulação glenoumeral. No caso em questão não houve documentação de luxação franca da articulação glenoumeral. As radiografias mostraram aumento do espaço articular, rotação interna do úmero e fratura do coracoide. Nas imagens de ressonância magnética, além das alterações observadas nas radiografias, foi identificada ruptura massiva do manguito rotador com interposição dos cotos dos tendões do supraespinal, do infraespinal e do subescapular no interior da articulação glenoumeral. Foi realizado tratamento cirúrgico confirmando a lesão e a interposição dos cotos do manguito. É importante que radiologistas e ortopedistas estejam familiarizados com esta entidade, que, pela sua raridade, pode ser negligenciada no atendimento do trauma do ombro.

Intraobserver and interobserver reliability of radial torsion angle measurements by a new and alternative method with computed tomography.

OBJECTIVE: To evaluate the intraobserver and interobserver reliability of radial torsion angle measurement using computed tomography. METHODS: Twelve pairs of cadaver radii and 116 forearms from 58 healthy volunteers were evaluated using axial computed tomography sections measured at the level of the bicipital tuberosity and the subchondral region of the radius. During digital imaging, the angle was formed by two lines, one diametrically perpendicular to the radial tubercle and the other tangential to the volar rim of the distal joint surface. Measurements were performed twice each by three observers. RESULTS: In cadaveric bones, the mean radial torsion angle was 1.48º (-6º - 9º) on the right and 1.62º (-6 º - 8º) on the left, with a mean difference between the right and left sides of 1.61º (0º - 8º). In volunteers, the mean radial torsion angle was 3.00° (-17° - 17°) on the right and 2.91° (-16°- 15°) on the left, with a mean difference between the sides of 1.58º (0º - 7º). There was no significant difference between each side. The interobserver correlation coefficient for the cadaver radii measurements was 0.88 (0.72 - 0.96) and 0.81 (0.58 - 0.93) for the right and left radius, respectively, while for the volunteers, the difference was 0.84 (0.77 - 0.90) and 0.83 (0.75 - 0.89), respectively. Intraobserver reliability was high. CONCLUSION: The described method is reproducible and applicable even when the radial tubercle has a rounded contour.

O emprego dos retalhos livres em pacientes queimados: experiência de 58 retalhos em 46 pacientes / Free tissue transfers in the management of burns: experience with 58 flaps in 46 patients

A grande maioria das queimaduras de terceiro grau é tratada com a excisão tangencial,seguida da enxertia de pele. No entanto, as deformidades secundárias são frequentes, principalmentenos membros superiores e na cabeça e pescoço. As contraturas causadas pelasqueimaduras graves podem ser tratadas das formas mais diversas. Aquelas limitadas às pequenasáreas podem ser tratadas com zetaplastias, enxertos ou retalhos locais; mas quandoa contratura é extensa é difícil atingir bons resultados com os métodos convencionais. Osautores descrevem a sistematização e a estratégia na reconstrução primária ou secundáriaem pacientes queimados com o emprego de 58 retalhos livres, em 44 pacientes.

Tangential excision is the debridement of necrotic tissue until viable tissue is reached. Thesecond phase of surgical treatment is wound closure. The gold standard of wound coverageis autologus skin grafting. However, results can be disappointing in severe burns that involvethe upper extremity and the neck. Fifty-eight free flaps for 46 patients with deep burns werereviewed retrospectively to determine indication, methods and outcomes.

Avaliaçäo da perda da correçäo no tratamento cirúrgico das fraturas da coluna torácica e lombar / Assessment of loss of correction in the surgical treatment of thoracic and lumbar spine fractures

Os autores avaliaram os resultados do tratamento cirúrgico de 39 pacientes com fraturas da coluna toraco-lombar. Foram utilizadas, como material de fixaçäo hastes de Harrington isoladamente ou associadas a amarrilhos de Luque e placas AO tipo DCP e 4,5mm com parafusos transpediculares. Analisaram o comportamento do segmento vertebral envolvido na fratura, com destaque especial para a perda da correçäo que ocorre tardiamente. Observaram perda da correçäo inicial em 51,3 por cento dos pacientes, que variou de 5§ a 27§. Correlacionaram essa perda de correçäo à lesäo do disco intervertebral, à lesäo do corpo vertebral e à insuficiência dos métodos convencionais de fixaçäo em manter a reduçäo
