Postural control characteristics of breast cancer (BC) survivors with chronic chemotherapy-induced neuropathy (CIN)
Archives of Physical Medicine and Rehabilitation(2024)
摘要
Research Objectives
To characterize neuromotor deficits associated with chronic CIN.
Design
Cross-sectional.
Setting
Breast oncology practice within an academic medical center.
Participants
BC survivors >40 years of age with chronic CIN, defined as persisting more than 3 months after their last dose of taxane-based chemotherapy. Participants were identified as having neuropathy through chart review. Research staff worked with treating oncologists to invite their eligible patients to participate in this study and to enroll patients who were interested.
Interventions
None.
Main Outcome Measures
Center-of-pressure (COP) based measures of postural control associated with falls risk and/or injury risk calculated per Prieto, et al. (1996) and Roerdink, et al. (2011).
Results
Sixty (60) survivors with CIN participated, ranging in age from 40 to 78 years old and from 3 months to 6 years post-chemotherapy end. Of this cohort, 52 (87%) demonstrated postural control outside of the normal range, as defined in Worthen-Chaudhari et al. (2018). Here we report descriptive statistics of the 52 survivors who demonstrated postural control dysfunction.
Conclusions
Among BC survivors over the age of 40, we found evidence that CIN can persist chronically up to 6 years after chemotherapy completion and can be associated with postural control dysfunction. Understanding the incidence and severity of motor control deficits associated with the sensory loss of CIN might be useful for clinical decision-making. In addition, postural control might be a viable target for interventional studies of CIN that seek to improve function as well as sensation. More research is warranted.
