A Weighted Vest Rehabilitation Protocol to Improve Gait in a Patient with Cerebellar Degeneration: A Case Report. Amy Belanger, BS, DPT Student, Kirsten Buchanan, PhD, PT, ATC University of New England, Doctor of Physical Therapy Program, Portland, Maine Background Cerebellar degeneration (CD) is a rare brain dysfunction that affects motor control. Ataxia is a common manifestation of CD, defined as the discoordination of the limbs or trunk. Interventions that have separately been found to be effective when treating ataxia are postural training, comprehensive physical therapy (PT) and weighted vest protocols. 1,2,3,4 While each of these treatments have individually been shown to decrease ataxia, they have not been used in combination. Case Description The patient was a 34-year-old female who presented with severe ataxia and impaired mobility. The patient was previously in good health and worked at the hospital. The patient was admitted to the inpatient rehabilitation unit for intensive PT, occupational therapy, and speech therapy. A comprehensive PT program including strengthening, endurance and balance training was utilized. Additionally, the patient wore a weighted vest and used a weighted walker when participating in transfers, gait training, and functional tasks. Over 3 weeks, she was seen for 21 visits. The patient’s personal rehabilitation goal was to return home to her husband and 3-year-old son. Discussion Studies have investigated the use of weighted vest protocols and comprehensive PT programs separately but not in combination. After 3 weeks of a combined weighted vest protocol and comprehensive PT program, the patient showed gains in all areas of strength, balance, transfers and gait. The complexity of her medical condition limited her ability to meet her long-term PT goals of complete independence, however, she was able to return home to her husband and 3-year-old son at discharge. A limitation of this case report was that 6 different physical therapists treated this patient over the course of her stay. Conclusion This patient appeared to make improvements in mobility after participating in strength, endurance and balance training and following the use of a weighted vest during functional tasks. The idiopathic cause of her condition made it difficult to anticipate the expected progression of her disease. Future studies should investigate the percent of body mass a weighted vest should be to have the most benefit for patients with CD. Purpose The purpose of this case report was to investigate a combined weighted vest protocol and comprehensive PT program for a 34-year-old with cerebellar degeneration.
