Validity and Responsiveness of Balance Measurements Using Posturography in Patients With Immune-Mediated Neuropathies
Background and Aims
Validated objective measures for balance in immune mediated neuropathies are lacking. In this study, we investigated the clinimetric properties of posturography using a force platform, a quantitative assessment of postural control.
Methods
We assessed patients with chronic inflammatory demyelinating polyneuropathy (CIDP) and IgM-related polyneuropathy (IgM-PNP) using sway parameters (path, area and amplitude) measured at multiple time points. Validity was investigated by assessing differences in sway path between patients with and without reported balance symptoms and by assessing correlations of sway path with (established) impairment measures related to balance, disability and quality of life (QoL). Responsiveness was assessed by means of an anchor-based approach, using a patient anchor and two disability scales.
Results
We included 52 CIDP and 13 IgM-PNP patients. In CIDP, sway path was 25% longer in patients reporting balance symptoms relative to patients without balance symptoms (p = 0.03). There was excellent reliability between consecutive measurements in both CIDP and IgM-PNP. Moderate to good correlations were observed between sway path and an ataxia scale (CIDP: Spearman's ρ = 0.46, 95% CI: 0.2–0.69; IgM-PNP: Spearman's ρ = 0.72, 95% CI: 0.28–0.96) while correlations with related disability measures and QoL were poor. Changes in sway parameters over time were not consistently associated with changes in other outcome measures.
Interpretation
Posturography measurements showed poor validity and responsiveness. Therefore, despite excellent reliability, using a force platform in clinical practice or trials for immune-mediated neuropathies cannot be recommended.
期刊介绍:
The Journal of the Peripheral Nervous System is the official journal of the Peripheral Nerve Society. Founded in 1996, it is the scientific journal of choice for clinicians, clinical scientists and basic neuroscientists interested in all aspects of biology and clinical research of peripheral nervous system disorders.
The Journal of the Peripheral Nervous System is a peer-reviewed journal that publishes high quality articles on cell and molecular biology, genomics, neuropathic pain, clinical research, trials, and unique case reports on inherited and acquired peripheral neuropathies.
Original articles are organized according to the topic in one of four specific areas: Mechanisms of Disease, Genetics, Clinical Research, and Clinical Trials.
The journal also publishes regular review papers on hot topics and Special Issues on basic, clinical, or assembled research in the field of peripheral nervous system disorders. Authors interested in contributing a review-type article or a Special Issue should contact the Editorial Office to discuss the scope of the proposed article with the Editor-in-Chief.
