RESUMO
Background Patients staying in acute rehabilitation often use large amounts of opioids during their stay. There are a number of reasons for this increased opioid exposure, including but not limited to daily exercises with physical and occupational therapists, increased demand on a healing body, and use of previously atrophying musculature. Some physiatrists have noticed that patients who concurrently are prescribed medications such as Robaxin seem to require fewer opioids during their stay in acute rehabilitation. This study aimed to determine the association between non-opioid analgesic use and total opioid load, as measured using morphine milligram equivalents (MMEs), during inpatient rehabilitation for traumatic brain injury. Methodology A retrospective study of individuals with a diagnosis of traumatic brain injury admitted to an acute inpatient rehabilitation program was performed. Non-opioid medications that were reviewed in the study included acetaminophen, amitriptyline, baclofen, diclofenac, gabapentin, ibuprofen, lidocaine, methocarbamol, nortriptyline, and pregabalin. Five of the most-used non-opioid medications (acetaminophen, diclofenac, gabapentin, lidocaine, and methocarbamol) were statistically analyzed using regression and analysis of variance to evaluate for any significant variables. Results Results showed that the average daily dose of acetaminophen has a significant effect on the average daily MME and that the average daily dose of gabapentin and methocarbamol each have a significant effect on the change of daily MME usage from admission to discharge from acute rehab (ΔMME). Results also showed that the mere presence of methocarbamol (regardless of daily or total dosage) had a significant effect on the ΔMME. Conclusions Based on these findings, physicians may want to consider prescribing acetaminophen, gabapentin, or methocarbamol for patients admitted for inpatient rehabilitation following traumatic brain injury who require high amounts of opioids.
RESUMO
Despite aggressive conventional therapy, lasting hemiplegia persists in a large percentage of stroke survivors. The aim of this article is to critically review the rationale behind targeting multiple sites along the motor learning network by combining robotic therapy with pharmacotherapy and virtual reality-based reward learning to alleviate upper extremity impairment in stroke survivors. Methods for personalizing pharmacologic facilitation to each individual's unique biology are also reviewed. At the molecular level, treatment with levodopa was shown to induce long-term potentiation-like and practice-dependent plasticity. Clinically, trials combining conventional therapy with levodopa in stroke survivors yielded statistically significant but clinically unconvincing outcomes because of limited personalization, standardization, and reproducibility. Robotic therapy can induce neuroplasticity by delivering intensive, reproducible, and functionally meaningful interventions that are objective enough for the rigors of research. Robotic therapy also provides an apt platform for virtual reality, which boosts learning by engaging reward circuits. The future of stroke rehabilitation should target distinct molecular, synaptic, and cortical sites through personalized multimodal treatments to maximize motor recovery.
