In addition, in certain circumstances severe hemiparetic patients were unable to generate sufficient isometric force and, in particular for MST, some post-stroke patients might be stronger than the instrument's reading capacity [13, 35, 38, 41, 42, 43]. Only hip extension aROM on the paretic side was found to have a relationship to gait speed. The previous literature neglects to consider hip extension directly, but only abnormalities in pelvic tilt or reduced hip flexion were reported. [PERSON] et al. [16] found that gait speed was positively associated with paretic hip extension strength in musculoskeletal models and, in addition to the ankle plantar-flexors, contributes to the forward acceleration of the trunk during walking. This finding is somewhat inconsistent with the finding of a correlation between hip flexors and speed. The kinematics of all lower limb joints in the sagittal plane and its relationship with spastic biaarticular muscles should be studied further. Data from the current study confirms the findings of [PERSON] et al. regarding the correlation between BI and gait speed, even if they used the Modified Barthel Index with sub-score (ambulation and stair climbing) [45]. There have been no previous studies analyzing a patient's functional capacities using the NEAS scale. As regards spatio-temporal gait parameters, a systematic review conducted by [PERSON] et al. [9] analyzed the mechanisms of gait speed change post-stroke and the recovery measures after physical therapy and showed how, in some studies, changes in spatiotemporal parameter results significantly correlated, as expected, with gait speed both for the hemiparetic and unaffected side. Further studies compared hemiparetic and healthy subjects' gait speed (normal and slow), confirming significant differences in the step length and duration of the double stance phase, the single-stance phase and the swing phase and cadence at the slow speed [9]. The results of the current study are in good agreement with these findings. The assessment of gait speed in stroke survivors is of paramount relevance because it is a valuable way to evaluate function and quality of life [46], and rehabilitation should aim to reach the best gait speed performance to these patients. A recent Cochrane review [6] highlighted how cardiorespiratory training alone or associated with resistance training can significantly increase the maximum walking speed in post-stroke hemiparetic patients. All the interventions analyzed, including specific gait-related training, resulted in positive effects, reflecting the task-related nature of training specificity, strictly related to measurements such as the BI. Patients in the current study were all included in an inpatient rehabilitation program after the stroke, followed later by inclusion in an APA program for managing residual chronic impairment. APA for stroke is a low-cost, feasible and well-accepted intervention, showing gain or stabilization in terms of walking speed and ADLs [47]. The current study has limitations.
