Clinical Assessment of Scapular Positioning in Musicians: An Intertester Reliability Study

Context:

The reliability of the measurement of the distance between the posterior border of the acromion and the wall and the reliability of the modified lateral scapular slide test have not been studied. Overall, the reliability of the clinical tools used to assess scapular positioning has not been studied in musicians.

Objective:

To examine the intertester reliability of scapular observation and 2 clinical tests for the assessment of scapular positioning in musicians.

Design:

Intertester reliability study.

Setting:

University research laboratory.

Patients or Other Participants:

Thirty healthy student musicians at a single university.

Main Outcome Measure(s):

Two assessors performed a standardized observation protocol, the measurement of the distance between the posterior border of the acromion and the wall, and the modified lateral scapular slide test. Each assessor was blinded to the other''s findings.

Results:

The intertester reliability coefficients (κ) for the observation in relaxed position, during unloaded movement, and during loaded movement were 0.41, 0.63, and 0.36, respectively. The κ values for the observation of tilting and winging at rest were 0.48 and 0.42, respectively; during unloaded movement, the κ values were 0.52 and 0.78, respectively; and with a 1-kg load, the κ values were 0.24 and 0.50, respectively. The intraclass correlation coefficient (ICC) of the measurement of the acromial distance was 0.72 in relaxed position and 0.75 with the participant actively retracting both shoulders. The ICCs for the modified lateral scapular slide test varied between 0.63 and 0.58.

Conclusions:

Our results demonstrated that the modified lateral scapular slide test was not a reliable tool to assess scapular positioning in these participants. Our data indicated that scapular observation in the relaxed position and during unloaded abduction in the frontal plane was a reliable assessment tool. The reliability of the measurement of the distance between the posterior border of the acromion and the wall in healthy musicians was moderate.     

Glenohumeral Rotational Range of Motion in Collegiate Overhead-Throwing Athletes During an Athletic Season

Context:

Repetitive throwing at high velocities leads to altered range of motion (ROM) in the dominant shoulder compared with the nondominant shoulder in overhead-throwing athletes. Loss of glenohumeral internal rotation (IR), or glenohumeral internal-rotation deficit (GIRD), is associated with shoulder injuries. Therefore, GIRD should be evaluated during the clinical examination of the thrower''s shoulder.

Objective:

To assess glenohumeral ROM in competitive baseball and softball athletes at 3 intervals over the course of an athletic season in order to (1) examine changes in ROM over time and (2) monitor the prevalence of GIRD.

Design:

Observational, repeated-measures study.

Setting:

Collegiate athletic training room.

Patients or Other Participants:

Forty-eight healthy National Collegiate Athletic Association (NCAA) Division I or Division II athletes (age  =  19 ± 1 years, height  =  174 ± 14 cm, mass  =  77.8 ± 18.1 kg; 19 softball, 29 baseball players).

Main Outcome Measure(s):

We measured glenohumeral IR, external rotation (ER), total arc (ER + IR), and GIRD at 3 times: prefall, prespring, and postspring. We calculated GIRD in 2 ways: as the difference in IR between dominant and nondominant shoulders and as the percentage of the total arc.

Results:

In the dominant shoulder, ER increased during the season (F_2,96  =  17.433, P < .001), but IR remained the same (F_2,96  =  1.839, P  =  .17). The total arc in the dominant shoulder increased between time intervals (F_2,96  =  14.030, P < .001); the mean difference between prefall and postspring measurements was 9.694° (P < .001), and the mean difference between prefall and postspring measurements was 10.990° (P < .001). In the nondominant shoulder, ER increased over the season (F_2,96  =  23.395, P < .001), but IR did not change over the season (F_2,96  =  0.087, P  =  .90). The total arc in the nondominant shoulder increased between prefall and prespring measurements and between prefall and postspring measurements (F_2,96  =  18.552, P < .001). No changes were noted in GIRD over time. However, more athletes with GIRD were identified with the GIRD (IR difference) calculation in prefall (n  =  6) than in prespring (n  =  1) and postspring (n  =  4) (Cochran Q  =  5.2, P  =  .07). In addition, more athletes with GIRD were identified with the GIRD (% total arc) calculation in postspring (n  =  6) than in prefall (n  =  5) or prespring (n  =  4) (Cochran Q  =  2.6, P  =  .27).

Conclusions:

Healthy NCAA Division I and Division II athletes did not display changes in glenohumeral IR over an athletic season. However, they gained in ER and total arc during the season in both shoulders. Future researchers should investigate changes over multiple seasons. The 2 methods of calculating GIRD identified different athletes as having GIRD, indicating that additional investigation is warranted to determine the clinical benefits of each method.     

Lateral scapular slide test and scapular mobility in volleyball players

Context:

The stability of the scapula in relation to the entire moving upper extremity is the key in the throwing sequence. The importance of scapular positioning in volleyball players has been well documented in the literature, but no one has compared scapular positioning between volleyball players and sedentary people.

Objective:

To compare measurements of scapular mobility obtained using the lateral scapular slide test between volleyball players and sedentary participants without shoulder impairments and to compare changes in scapular mobility in players according to the number of years of sport participation.

Design:

Cross-sectional study.

Setting:

University research laboratory.

Patients or Other Participants:

A total of 121 people at a single university volunteered. Of these, 67 were sedentary (age = 24.3 ± 2.34 years, height = 1.69 ± 0.09 m, mass = 65.1 ± 11.91 kg); 54 were volleyball players from 4 professional teams and were separated into 2 groups according to their years of sport participation. The first group was named young players (n = 31; age = 17.7 ± 2.58 years, height = 1.83 ± 0.10 m, mass = 68.3 ± 12.21 kg, sport participation ≤ 9 years), and the second group was named old players (n = 23; age = 26.9 ± 3.39 years, height = 1.95 ± 4.38 m, mass = 90.7 ± 5.75 kg, sport participation ≥ 10 years).

Main Outcome Measure(s):

Study participants completed a rating scale for pain and a questionnaire about demographic and shoulder problems. One assessor performed the lateral scapular slide test and additional flexibility measurements around the shoulder girdle. Flexibility (external rotation, internal rotation) and scapular position (1, 2, 3) were compared among groups (young players, old players, sedentary people) and between sides (dominant, nondominant).

Results:

In sedentary participants, we found differences for position 1 (t₆₆ = 3.327, P = .002), position 2 (t₆₆ = 2.491, P = .004), position 3 (t₆₆ = 2.512, P = .006), and internal rotation (t₆₆ = 2.592, P = .001) between the dominant and nondominant sides. In old players, we found differences for position 2 between the dominant and nondominant sides (t₂₂ = 2.956, P = .004). For position 2 (F_2,118 = 4.265, P = .02) and position 3 (F_2,118 = 4.702, P = .01), we found differences between young and old players. For internal rotation, we found differences between sedentary and old players (F_2,118 = 6.578, P = .002) and between young and old players (F_2,118 = 3.723, P = .01).

Conclusions:

Clinicians evaluating overhead athletes need to remember that asymmetric scapular posture between the dominant and nondominant sides in unilateral overhead athletes might be normal and not necessarily related to injury.     

A Comparison of Whole-Body Vibration and Resistance Training on Total Work in the Rotator Cuff

Context:

Whole-body vibration machines are a relatively new technology being implemented in the athletic setting. Numerous authors have examined the proposed physiologic mechanisms of vibration therapy and performance outcomes. Changes have mainly been observed in the lower extremity after individual exercises, with minimal attention to the upper extremity and resistance training programs.

Objective:

To examine the effects of a novel vibration intervention directed at the upper extremity as a precursor to a supervised, multijoint dynamic resistance training program.

Design:

Randomized controlled trial.

Setting:

National Collegiate Athletic Association Division IA institution.

Patients or Other Participants:

Thirteen female student-athletes were divided into the following 2 treatment groups: (1) whole-body vibration and resistance training or (2) resistance training only.

Intervention(s):

Participants in the vibration and resistance training group used an experimental vibration protocol of 2 × 60 seconds at 4 mm and 50 Hz, in a modified push-up position, 3 times per week for 10 weeks, just before their supervised resistance training session.

Main Outcome Measure(s):

Isokinetic total work measurements of the rotator cuff were collected at baseline and at week 5 and week 10.

Results:

No differences were found between the treatment groups (P > .05). However, rotator cuff output across time increased in both groups (P < .05).

Conclusions:

Although findings did not differ between the groups, the use of whole-body vibration as a precursor to multijoint exercises warrants further investigation because of the current lack of literature on the topic. Our results indicate that indirectly strengthening the rotator cuff using a multijoint dynamic resistance training program is possible.

Reliability and Validity of the Upper Limb Physician's Rating Scale in Children with Cerebral Palsy

Purpose

The Upper Limb Physician''s Rating Scale (ULPRS) is a tool that assesses movement quality of the upper limbs. It is used as an outcome measure after botulinum toxin type A injection in children with cerebral palsy (CP). This study aimed to investigate the reliability and validity of the ULPRS in children with spastic CP.

Materials and Methods

Thirty children with spastic CP (M:F=17:13) aged 5 to 13 years old were recruited. The ULPRS was scored based on recorded videotapes by four physicians on two separate occasions. The Melbourne Assessment of Unilateral Upper Limb Function (MUUL) was scored by an occupational therapist. Intraclass correlation coefficients (ICCs), 95% confidence intervals and weighted kappa statistics were calculated for the scores of ULPRS to obtain interrater and intrarater reliability. The relationship between ULPRS and MUUL was assessed using Pearson correlation coefficients.

Results

The ICCs for the total ULPRS scores were 0.94 between raters and 0.99 to 1.00 within raters. The weighted kappa statistics for subitem scores for the ULPRS ranged from 0.67 to 1.00 within raters and from 0.46 to 0.86 between raters. The relationship between ULPRS and MUUL was strong (Pearson correlation coefficient=0.751; p<0.05).

Conclusion

The results demonstrated the high reliability of the total ULPRS score within and between raters. A significant concurrent validity between ULPRS and MUUL also supports the clinical utility of the ULPRS as an outcome measure of spastic upper limb in children with CP.

The Diagnostic Validity and Reliability of an Internet-Based Clinical Assessment Program for Mental Disorders

Background

Internet-based assessment has the potential to assist with the diagnosis of mental health disorders and overcome the barriers associated with traditional services (eg, cost, stigma, distance). Further to existing online screening programs available, there is an opportunity to deliver more comprehensive and accurate diagnostic tools to supplement the assessment and treatment of mental health disorders.

Objective

The aim was to evaluate the diagnostic criterion validity and test-retest reliability of the electronic Psychological Assessment System (e-PASS), an online, self-report, multidisorder, clinical assessment and referral system.

Methods

Participants were 616 adults residing in Australia, recruited online, and representing prospective e-PASS users. Following e-PASS completion, 158 participants underwent a telephone-administered structured clinical interview and 39 participants repeated the e-PASS within 25 days of initial completion.

Results

With structured clinical interview results serving as the gold standard, diagnostic agreement with the e-PASS varied considerably from fair (eg, generalized anxiety disorder: κ=.37) to strong (eg, panic disorder: κ=.62). Although the e-PASS’ sensitivity also varied (0.43-0.86) the specificity was generally high (0.68-1.00). The e-PASS sensitivity generally improved when reducing the e-PASS threshold to a subclinical result. Test-retest reliability ranged from moderate (eg, specific phobia: κ=.54) to substantial (eg, bulimia nervosa: κ=.87).

Conclusions

The e-PASS produces reliable diagnostic results and performs generally well in excluding mental disorders, although at the expense of sensitivity. For screening purposes, the e-PASS subclinical result generally appears better than a clinical result as a diagnostic indicator. Further development and evaluation is needed to support the use of online diagnostic assessment programs for mental disorders.
