Active Shoulder Elevation

Decent Essays
1. What are the major goal(s) of this article?
Research by Kolber, Fuller, Marshall, Wright and Hanney (2012) supports that the goal of this study was to investigate the intrarater reliability, interrater reliability and concurrent validity of active shoulder elevation in the scapular plane (scaption) using a digital inclinometer and goniometer (p.161, 162).
2. What does the goniometer purport to do, and how does it do it?
According to Kobler et al., (2012) the goniometer is used to perform examination of joints mobility and in this study it measures active shoulder elevation in scapular plane (scaption) (p. 161-163). The participant first brings the dominant hand (tested hand) in the end range of scaption with thumb pointed towards the ceiling

As per to Kobler et al., (2012), they were asked to sign the informed consent document approved by the Institutional Review Board at Nova Southeastern University, and they were given complete information about the study even before starting the research. The study had exclusion criteria as well. The researchers made sure they don’t include participants with any cervical spine or upper extremity pain during data collection or participants who are receiving therapeutic care on their dominant hand due to recent shoulder surgery. Otherwise, this would have led to err in the measurement. The 3rd year DPT students who were supposed to perform the measurements were given 6 hours practice trials with the instruments in addition to their academic exposure. This was another way to avoid any measurement error. The measurements were taken in two ways inter and intra raters way. And both the raters were blinded to the results throughout the investigation. This way they avoid result bias. For accuracy, the digital inclinometer was fixed to zero before taking any measurement. Also, to ensure validity the measurement from goniometer and inclinometer was taken in one motion of scaption. All the participants were asked to perform a same 3 min warm up and were asked to perform passive motion first and then active motion. This way the participant was familiarized with the requested motion…show more content…
Therefore its usage has to be investigated (p.162). In this study the authors Kobler et al., (2012), used healthy participants, that’s why on should not correlate their ranges with population having shoulder pathology. Also, in this study the asymptomatic participants were asked to hold their arm in position after goniometric measurements to perform inclinometric measurements. This method should not be easy in case of participants with shoulder pathology. This will affect the result of the study. The other limitation of this study was the age group of the participants. In clinical settings we usually see patients ranging from 44 years however, in this study they investigated young adults with mean average age of 26 years. Therefore, this study cannot be generalized for people of increasing or decreasing age group. Both, the goniometer as well as the digital inclinometer needs to be calibrated before using or else results in err. Another limitation to this study is that, the inclinometer measurement varies from goniometer measurement with different body types for an e.g. thinner people (ectomorphs) are leaner as compared slight heavy people (endomorphs and mesomorphs). Therefore while measuring scaption the inclinometer measurement varies due to
