The goal of this study is to compare between Eccentric training and conventional therapy in sub-acute stroke survivors. The primary objective of this study is to evaluate improvements in gait speed after four months of ET in comparison to conventional therapy for patients with sub-acute stroke. Secondary objectives involve assessing: i) modifications in neuromuscular parameters of PF, ii) changes in muscle stiffness within PF during passive mobilization and active force generation, and iii) modifications in architectural parameters of PF.
This study will be a single-blinded, controlled, randomized design, wherein participants will be randomly assigned to one of two groups: the Conventional Therapy Group (CTG) or the Eccentric Training Group (ETG). Both groups will undergo a comprehensive series of assessments at three key time points: Ji (initial assessment), Jint (intermediate assessment), and Jf (final assessment). The study will commence with a recruitment phase, followed by a screening phase. Subsequently, there will be a 4-week period allocated for experimental testing before the intervention, and an additional 4 weeks for experimental testing after the intervention. These assessments will encompass a wide range of evaluations, including clinical health assessments, biomechanical assessments, neuromuscular evaluations, and functional assessments

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| CTG | Active Comparator | In conventional therapy, the treatment plan is determined based on medical opinion. After admission, each patient undergoes several multidisciplinary assessments aimed at objectively determining the care based on their needs. In this group, patients received only conventional rehabilitation. This will carry out in the same manner as a regular practice of the clinic. 3 sessions per week |
|
| ETG | Experimental | In the absence of a standardized eccentric isokinetic training protocol established for hemiparetic subjects on the plantar flexor muscles, the protocol designed for this study drew inspiration from the one established by Clark and Patten. (2013) and by Harris-Love et al. (2017).This protocol allows the introduction of an eccentric stimulus for individuals who are new to this type of training and progressively advances their program to include workload levels sufficiently to stimulate muscle plasticity optimally, thereby inducing skeletal muscle adaptations. 3 sessions per week |

| Eccentric training | Procedure | The eccentric program will last for 16 weeks, with a frequency of 2 sessions per week, totalling 32 sessions. At least 1 day of rest will be required between two training sessions. The participants will be placed in the similar position of the neuromuscular assessments (reference position). The Biodex System 4 dynamometer settings for the exercise sessions were also like the settings used for the assessments. The training program will be divided into two phases: a familiarization phase and a progression phase |

| gait speed (m/s) through the 10-meter walking test. | An analysis of the walking pattern will be conducted to quantify the evolution of spatio-temporal and barometric parameters of walking and their asymmetry. | initial assessment in the first week of the inclusion, intermediate assessment at 6 weeks of the inclusion, and final assessment at 12 weeks of the inclusion |
| Measure | Description | Time Frame |

| Biomechanical proprieties | muscle stiffness, as expressed by the shear modulus (µ, in Kpa), will be assessed during passive ankle joint mobilization from dorsiflexion to plantar flexion and during maximal voluntary isometric contraction of Plantar flexors | initial assessment in the first week of the inclusion, intermediate assessment at 6 weeks of the inclusion, and final assessment at 12 weeks of the inclusion |
