## 4 Discussion
In meta-analyses and systematic reviews [17, 18], we found different reports of patients included in the studies, both in terms of the AIS classification and outpatient status. Perhaps this can be explained due to the social, cultural, and genetic differences between countries, or the access to medical services and rehabilitation strategies. Also analyzing different studies, we concluded that there was a relationship between converting the AIS degree to a better one according to the severity of the SPI or intramedullary lesion length [16]. Moreover, locomotor training improves the AIS grade gait speed to levels sufficient for independent in-home or community ambation after chronic motor incomplete SCI [19]. In the study, we also looked at the various drugs used by the patients, and the most common type of medication used was a lack of medication in T-SCI, which was a normal result considering that they are younger and healthier, while antihypertensive medication was the most commonly used in NT-SCI [20, 21]. It is well known that in SCIs, the most common complication observed in both groups was a urinary tract infection. [PERSON] et al. compared the complications between traumatic and nontraumatic SCIs and found no statistically significant differences between the two groups regarding urinary tract infections. Moreover, the authors identified other infections such as pneumonia and wound infections. It is important to determine the risk of infections at admission to a hospital because it has an important implication for the rehabilitation outcomes, individualized patient management, and long-term outcome of individuals with NT-SCI. That is why we calculated the Carmeli score, in order to identify patients susceptible to being colonized with multidrug-resistant bacteria at the beginning of the hospitalization. The highest numeric value of the three criteria represents the final value of the Carmeli score (1, 2, or 3). The final score allowed us to classify patients as follows: score 1 (community-acquired infections with microorganisms susceptible to classic antibiotics), score 2 (probably healthcare-associated or community-acquired infections but with a high probability of resistant or multidrug-resistant strains), and score 3 (maximum prediction for nosocomial infections with resistant or multidrug-resistant strains) [22]. In our study, we found a higher Carmeli score in the T-SCI group (1.78) versus the NT-SCI group (1.68), but without statistical significance. There is no data in the scientific literature regarding this score in SCIs. An important issue to establish the rehabilitation goals is to evaluate the fall risk. [PERSON] et al. evaluated the falls in SCIs, acquired brain injury, and a neuromusculoskeletal disease, and the type of disease was not a significant predictor of the fall rate in the multivariable analysis, but these results may be useful when developing and timing fall prevention interventions for inpatient rehabilitation [23, 24]. This is consistent with previous reports finding that most falls occur within a few weeks of admission, at 5-7 weeks. We found that the risk of falls is higher (\(p<0.05\)) at admission in the T-SCI group, but the risk decreases statistically significantly in both groups (\(p<0.001\)) after only 2 weeks of treatment. We also investigated the pain, using the VAS score [25], and we found that, at admission, there were higher values in NT-SCI (\(p<0.001\)), and at discharge, the score decreased in both groups (\(p<0.001\)). In previous studies [8, 9, 26], although spasticity and neuropathic pain are quite common in both the nontraumatic and traumatic groups, these conditions were less prevalent in the nontraumatic group, even if the pain could be visceral, nociceptive, or neuropathic [27]. Regarding the functional status, we evaluated FIMm, FIMc, and FIMt. The results have shown a higher level at admission for NT-SCI for all three parameters, and all increase with a statistical significance (\(p<0.001\)) in T-SCI as well as in the NT-SCI group.
