“…Acute reductions in tendon thickness have been previously, though not exclusively,38 39 observed following intense or prolonged exercise in vivo 19–24. Hypothesised to largely reflect the movement of fluid associated with load-induced alignment of the solid phase of the tendon matrix, the findings of the current study are consistent with in vitro observations in animal models in which static and cyclic loading have been shown to result in reduced tendon thickness, rapid unbinding and extrusion of intratendinous fluid and visible loss of water and glycosaminoglycans 40–42.…”

“…Several studies have assessed the shoulder by ultrasonography before and after performing a specific task, yet the task performed did not coincide in any of these, including our present study. [19][20][21] In the first study, a decrease in the biceps tendon echogenicity was detected. 19 In our study, LBTT decreased in CG and did not change significantly in MWUs.…”

“…21 The SST appearance was not significantly influenced by demographic parameters or biomechanics, as seen previously. 20 This might be because of the fact that the supraspinatus was visualized transversally as opposed to the longitudinal images obtained of the biceps tendon. Indeed, collagen fiber organization is less evident in the transverse view.…”

“…Acute tendon injuries after different tasks have been investigated previously. [19][20][21] However, to our knowledge, no studies have focused on changes that might occur after a controlled and intense manual wheelchair propulsion task. In addition, it might be interesting to analyze whether such changes could be related to the shoulder joint forces applied or to the basal condition of the shoulder.…”

Shoulder kinetics and ultrasonography changes after performing a high-intensity task in spinal cord injury subjects and healthy controls

Study design: This is a prospective and comparative study between two groups. Objectives: The objective of this study was to compare the changes in shoulder joint forces and their moments, as well as any possible ultrasound changes, when subjects with spinal cord injury (SCI) and healthy controls (CG) undertake a high-intensity manual wheelchair propulsion test. Setting: This study was conducted in an inpatient SCI rehabilitation center. Methods: A group of 22 subjects with SCI at level T2 or below who use a manual wheelchair (MWU), categorized as AIS grade A or B, were compared with a CG of 12 healthy subjects. Subjects in each group performed a high-intensity wheelchair propulsion test. The variables analyzed were shoulder joint forces and the moments at the beginning and at the end of the test. Ultrasound variables before and after the propulsion test were also analyzed. Correlations were also drawn between the ultrasonography and demographic variables. Results: In both groups, peak shoulder forces and moments increased after the test in almost all directions. No differences in the ultrasound parameters were found. A greater long-axis biceps tendon thickness (LBTT) was associated with more shoulder pain according to WUSPI or VAS (r = 0.428, Po0.05 and r = 0.452, Po0.05, respectively). Conclusions: Shoulder joint forces and moments increase after an intense propulsion task. In subjects with SCI, these increases center on forces with less chance of producing subacromial damage. No changes are produced in ultrasonography variables, whereas a poorer clinical and functional evaluation of the shoulder of the MWUs appears to be related to a thicker long-axis biceps tendon.

“…One group of researchers is using sonography to evaluate overuse syndromes and changes in musculoskeletal structures of the shoulder and wrist as a result of their use in wheelchair propulsion (Collinger, Impink, Ozawa, & Boninger, 2010;Impink, Collinger, & Boninger, 2011). A second research group is exploring methods for the use of sonography screening in early identification of carpal tunnel syndrome and upper-extremity work-related musculoskeletal disorders (Evans, Roll, Li, & Sammet, 2010;Evans & Sommerich, 2009;Roll, Evans, Li, Freimer, & Sommerich, 2011;Roll, Evans, Volz, & Sommerich, 2013).…”

Occupational therapy practice is grounded in the delivery of occupation-centered, patient-driven treatments that engage clients in the process of doing to improve health. As emerging technologies, such as medical imaging, find their way into rehabilitation practice, it is imperative that occupational therapy practitioners assess whether and how these tools can be incorporated into treatment regimens that are dually responsive to the medical model of health care and to the profession’s foundation in occupation. Most medical imaging modalities have a discrete place in occupation-based intervention as outcome measures or for patient education; however, sonographic imaging has the potential to blend multiple occupational therapy practice forms to document treatment outcomes, inform clinical reasoning, and facilitate improved functional performance when used as an accessory tool in direct intervention. Use of medical imaging is discussed as it relates to occupational foundations and the professional role within the context of providing efficient, effective patient-centered rehabilitative care.

Effect of an Intense Wheelchair Propulsion Task on Quantitative Ultrasound of Shoulder Tendons

Abstract: QUS has proven to be sensitive to risk factors for tendon pathology. Future studies can apply grayscale-based QUS to study the development and prevention of repetitive strain injuries, particularly on an individual basis.
