“…They even discuss proprioceptive deWcits of 0.2°-0.8° relative to their clinical relevance and conclude that proprioceptive deWcits as measured with the current methods have only a low to moderate clinically relevant correlation with function. For shoulder proprioception authors like Cuomo et al [5] found proprioception diVerences of 2° after shoulder replacement and adjudged them as clinical relevant also as reported Pötzl et al [16] who found a proprioception change of 4°. In the present study on purpose we used an active and not a passive angle reproduction test to advance clinical relevance.…”

“…The AAR has been used to assess shoulder proprioception before, for example, in shoulder instability in which Pötzl et al [16] examined the proprioceptive capabilities of 14 patients with recurrent anterior shoulder instability preoperatively and at least 5 years postoperatively using the AAR test. In their series the joint position sense improved on average about 4° in abduction, Xexion, and rotation.…”

The aim of the study was to assess proprioception after shoulder arthroplasty. Twenty-six patients were enrolled who underwent total shoulder arthroplasty (TSA) (n=13) or hemi-arthroplasty (n=8) for shoulder osteoarthritis or reversed arthroplasty (n=5) for cuff tear arthropathy. All patients were examined before the operation and then again six months thereafter in a motion analysis study with an active angle-reproduction (AAR) test. In all groups the AAR deteriorated at 60°flexion (from 5.5°[SD 2.8] to 7.6°[SD 2.7]; p=0.007) and at 30°external rotation (ER) (from 6.5° [SD 3.6] to 7.3°[SD 4.8°]; p=0.023) six months after surgery. In the subgroup of TSA, there was deterioration at 30°ER (p=0.036). Otherwise, there were no significant changes within or among the subgroups. Proprioception, assessed by the AAR test, remained unchanged or deteriorated six months after shoulder arthroplasty. This might be related to the reduced pain or to the relatively short follow-up period.

“…This cycle of events is illustrated by the paradigm of pathophysiology that clinicians and researchers use to identify prospective interventions, such as surgery, rehabilitation, and prevention ( Figure 1). In 2 studies, researchers 12,13 have examined the effects of shoulder surgery on the SMS. However, because of the limitations in the design and methods employed in each study, the precise effects of surgery on upper extremity SMS function are unclear.…”

Context: Clinicians use neuromuscular control exercises to enhance joint position sense (JPS); however, because standardizing such exercises is difficult, validations of their use are limited.Objective: To evaluate the acute effects of a neuromuscular training exercise with a handheld vibrating dumbbell on elbow JPS acuity.Design: Crossover study. Setting: University athletic training research laboratory.Patients or Other Participants: Thirty-one healthy, collegeaged volunteers (16 men, 15 women, age 5 23 6 3 years, height 5 173 6 8 cm, mass 5 76 6 14 kg).Intervention(s): We measured and trained elbow JPS using an electromagnetic tracking device that provided auditory and visual biofeedback. For JPS testing, participants held a dumbbell and actively identified the target elbow flexion angle (906) using the software-generated biofeedback, followed by 3 repositioning trials without feedback. Each neuromuscular training protocol included 3 exercises during which participants held a 2.55-kg dumbbell vibrating at 15, 5, or 0 Hz and used software-generated biofeedback to locate and maintain the target elbow flexion angle for 15 seconds.Main Outcome Measure(s): We calculated absolute (accuracy) and variable (variability) errors using the differences between target and reproduced angles.Results: Training protocols using 15-Hz vibration enhanced accuracy and decreased variability of elbow JPS (P # .005), whereas 5-Hz vibration did not affect accuracy (F 1,61 5 2.625, P 5 .100) but did decrease variability (F 1,61 5 7.250, P 5 .009). The control condition and 0-Hz training protocol had no effect on accuracy or variability (P $ .200).Conclusions: Our results suggest these neuromuscular control exercises, which included low-magnitude, low-frequency handheld vibration, may enhance elbow JPS. Future researchers should examine vibration of various durations and frequencies, should include injured participants and functional multijoint and multiplanar measures, and should examine long-term effects of training protocols on JPS and injury.
