Background A higher risk of shoulder injury in the athletic and non-athletic population is frequently associated with strength deficits. Therefore, shoulder strength assessment can be clinically useful to identify and to quantify the magnitude of strength deficit. Thus, the aim of this study was to evaluate the validity and reliability of a DiCI (a new hand-held dynamometer) for the measurement of shoulder flexion and abduction strength in asymptomatic and symptomatic subjects. Methods Forty-three recreational athletes (29 males and 14 females; age: 22.1 ± 0.47 years; body mass: 68.7 ± 13.1 kg; height = 173.3 ± 9.7 cm) and 40 symptomatic subjects (28 males and 12 females; age: 49.9 ± 8.1 years; body mass: 70.6 ± 14.3 kg; height = 171.7 ± 9.0 cm) completed shoulder flexion and abduction strength tests in two identical sessions one-week apart. Both types of movement were evaluated at 45º and 90º. Results Relative reliability analysis showed excellent intra-class correlation coefficients (ICC) for all evaluated movements (ICC range = 0.90 to 0.99). Absolute reliability analysis showed a standard error of measurement (SEM) ranging from 1.36% to 2.25%, and minimal detectable change (MDC) ranging from 3.93% to 6.25%. In conclusion, the DiCI is a valid and reliable device for assessing shoulder strength both in recreational athletes and in subjects with restricted mobility and loss of strength.

Abstract Introduction: A sphygmomanometer is an instrument commonly used to measure blood pressure that can potentially be used to objectively assess shoulder isometric muscle strength. Objective: To establish the criterion validity and the intra-rater reliability of the sphygmomanometer for the assessment of shoulder isometric muscular strength compared to the handheld dynamometer. To determine if there is a statistically significant difference for shoulder strength between dominant and non-dominant sides. Methods: A test-retest study design was developed, where a rater assessed shoulder flexion and abduction isometric strength of 13 healthy university students, using a commercially available sphygmomanometer and a handheld dynamometer. Results: The criterion validity of the sphygmomanometer was found to be good for both right and left shoulder flexion and abduction strength assessment (Pearson’s r = 0.90-0.97). The intra-rater reliability of the sphygmomanometer was calculated to be good for both right and left flexion and abduction (ICC = 0.96-0.99). The handheld dynamometer also showed good intra-rater reliability for each of the strength measures assessed (ICC = 0.94-0.98). Significant differences (p < 0.01) were identified between dominant and non-dominant sides for shoulder strength. Conclusion: A sphygmomanometer is a simple and easily accessible tool that provides clinicians with accurate objective values for isometric shoulder strength assessment.

PURPOSE: Cellists sustain high levels of playing-related injury and are particularly susceptible to right shoulder pain, yet no studies have attempted to propose a mechanism for disease or establish possible causal factors. The aim of this study was to investigate shoulder injury levels and causes in two populations: professional orchestral cellists and college-level student cellists. METHODS: A questionnaire and physical testing protocol was applied to both groups of participants, eliciting information on lifestyle, playing habits, and self-reported injury rates as well as physical data on shoulder strength, range of motion, and signs of injury. RESULTS: Right shoulder injuries are common among both student (20%) and professional (42%) cellists and seem to be associated with measures indicating potential lack of strength in the scapular stabilisers as well as potential degenerative changes in the rotator cuff. Significant differences were found in the lifestyle and playing habits of the two groups. There were increased signs of pain and stiffness in the professionals and evidence of decreased muscular support in the students. Male cellists showed less scapular stability; female cellists, however, generally had higher levels of pain. CONCLUSIONS: These results indicate that injuries at the shoulder, potentially involving impingement-type pathologies, are a common cause of pain in cellists. Based on this study, future research for cello players could focus on targeted interventions, such as exercises for the scapular stabilisers and muscles of the rotator cuff.

Purpose:This study determined the validity and reliability of a new specific field test that was based on the scientific data from the latest research.Methods:Seventeen international-level karatekas participated in the study: 14 men (age 24.1 ± 4.6 y, body mass 65.7 ± 10.8 kg) and 3 women (age 19 ± 3.6 y, body mass 54.1 ± 0.9 kg). All performed the new karate-specific test (KST) 2 times (test and retest sessions were carried out on separated occasions 1 wk apart). Thirteen men also performed a laboratory test to assess maximal oxygen uptake (VO2max).Results:Test–retest results showed the KST to be reliable. Peak oxygen uptake (VO2peak), peak heart rate (HRpeak), blood lactate concentration, rating of perceived exertion, and time to exhaustion (TE) did not display a difference between the test and the retest. The SEM and ICC for relative and absolute VO2peakand TE were <5% and >.90, respectively. Significant correlations were found between VO2peak(mL · kg−1· min−1) and TE measured from the KST (r= .71, 95%CI 0.35–0.88,P< .0001). There was also no significant difference between VO2peakmeasured from the KST and VO2maxrecorded from the cycle-ergometer laboratory test (55.1 ± 4.8 vs 53.2 ± 6.6 mL · kg−1· min−1, respectively;t= –1.85, df = 12,P= .08,dz= 0.51 [small]). The Bland and Altman analyses reported a mean difference (bias) ± the 95% limits of agreement of 1.9 ± 7.35 mL · kg−1· min−1.Conclusions:This study showed that the new KST test, with effort patterns replicating real karate combat sessions, can be considered a valid and reliable karate-specific field test for assessing karatekas’ endurance fitness.
