Impact of energy intake on the activities of daily living in patients with cervical spinal cord injury undergoing post-acute rehabilitation.

To investigate the association between sufficient energy intake and improvement in activities of daily living (ADL) after hospitalization in patients with cervical spinal cord injury (CSCI) undergoing post-acute rehabilitation. Retrospective cohort study. Post-acute care hospital from September 2013 to December 2020. Patients with CSCI admitted to a post-acute care hospital for rehabilitation. Not applicable. Multiple regression analysis was performed to investigate the relationship of sufficient energy intake to Motor Functional Independence Measure (mFIM) gain, mFIM score at discharge, and body weight change during hospitalization. In total, 116 patients (104 men and 12 women), median age: 55 (interquartile range [IQR] 41-65) years were included in the analysis. Then, 68 (58.6%) were in the energy-sufficient group, and 48 (41.4%) patients were classified under the energy-deficient group. The two groups did not significantly differ in terms of mFIM gain and mFIM score at discharge. The energy-sufficient group maintained body weight change during hospitalization than the energy-deficient group (0.6 [-2.0-2.0] vs. -1.9 [-4.0--0.3],  < 0.001). Multiple regression analysis showed no association between sufficient energy intake and outcomes. Sufficient energy intake within the first 3 days of admission did not affect ADL improvement during hospitalization in patients with a post-cute CSCI undergoing rehabilitation.
