Proprioception assessment in subjects with idiopathic loss of shoulder range of motion: joint position sense and a novel proprioceptive feedback index.

We examined the effects of elevation range and plane on shoulder joint proprioception in subjects with idiopathic loss of shoulder range of motion (ROM). Joint position sense (JPS) and a novel proprioceptive feedback index (PFI), including difference magnitude and the similarity index, were used to assess proprioception. Twelve subjects (eight male, four female) with involved stiff shoulders and normal opposite shoulders were recruited from a university hospital. Subjects attempted to repeat six target positions. Target positions consisted of arm elevation in three planes (frontal, scapular, and sagittal planes) and two ranges (end/mid range). Six trials of each target position were used to determine acceptable trials for stabilization of the data, less than 5% of the cumulative mean values for at least three successive trials. The data stabilized at the sixth repetition. Compared to control shoulders, involved shoulders had enhanced proprioception during end range movements (p < 0.05). The magnitude of the repositioning error and difference magnitude decreased (1.6 degrees -3.5 degrees for repositioning error and 22.2 degrees -62.1 degrees for difference magnitude), whereas similarity index improved at end range movements compared to mid range movements (p < 0.05) in involved stiff shoulders. Results of JPS and PFI suggest that both capsuloligamentous and musculotendinous mechanoreceptors play an important role in proprioception feedback during active movements in subjects with idiopathic loss of shoulder ROM.

An investigation into the effect of number of trials during proprioceptive testing in patients with patellofemoral pain syndrome.

The purpose of this study was to investigate the effect of increasing the number of test trials in the assessment of knee joint position sense, in a group of patellofemoral patients, and second, to investigate the effects of joint angle and type of test. Thirty-two patients with a diagnosis of patellofemoral pain syndrome were admitted to this study. Knee joint position sense was measured by performing an ipsilateral matching activity at target angles of 20 degrees and 60 degrees using two techniques; Passive Angle Reproduction (PAR), and Active Angle Reproduction (AAR). The results show that five repetitions are required for AAR and six for PAR. A two-way repeated-measures ANOVA showed that there was no significant difference (p = 0.559) in the accuracy of angle reproduction for the two angles (60 degrees and 20 degrees ); however, there was a significant difference (p = 0.001) between the two types of test (AAR and PAR). The results of this study have implications for clinicians and researchers who examine knee joint proprioception as part of functional assessment in a variety of knee joint pathologies including PFPS. A "quick" one-off assessment of knee joint position sense may give erroneous data; subjects need to have several trials before a true picture of their proprioceptive status emerges. Type of testing performed, active or passive, is also important, although the angle of testing may not be relevant.
