Reduction in isometric strength of the scapulohumeral muscles is a commonly seen impairment in overhead athletes afflicted with shoulder impingement syndrome (SIS). The purpose of this study was to compare the effects of two different treatment programs: progressive resistance exercises plus manual therapy (PRE plus MT) and motor control exercises (MCE), on isometric strength of upper trapezius (UT), middle trapezius (MTr), lower trapezius (LT), serratus anterior (SA), supraspinatus (Supr.), anterior deltoid (A.D), and latissimus dorsi (LD). 80 male university-level overhead athletes clinically diagnosed with SIS were randomly allocated into either of the two groups: PRE plus MT and MCE group. Athletes in the PRE plus MT group underwent graduated exercises with resistance elastic band, stretching exercises, and mobilization of the thoracic and shoulder joints. MCE group was submitted to motor control exercises in varied planar positions. Athletes in both groups underwent management 3 times a week for 8 weeks. Isometric strength of UT, MTr, LT, Supr, A.D, SA, and LD was measured at three-time points: baseline, 4th week, and 8th week. Relative to baseline, both interventions were found to be effective in increasing and optimizing the isometric strength of muscles (

0.05
) except for supraspinatus in the MCE group (
p
>
0.05
). However, athletes in PRE plus MT group presented a more pronounced increase in isometric strength than those in the MCE group. Between groups analysis found the largest isometric strength improvement in PRE plus MT group for A.D, followed by Supr. and UT muscles (
p
<
0.05
; effect size: 0.39 to 0.40). The study concluded that compared to MCE, PRE plus MT provides greater improvement in the isometric strength of scapulohumeral muscles.
Background Balance and gait impairments are the most common motor deficits due to stroke, limiting the patients' daily life activities and participation in society. Studies investigating effect of task-specific training using biomechanical balance and gait variables (i.e. kinetic and kinematic parameters) as well as posturography after stroke are scarce. Objectives The primary aim of this study is to assess the efficacy and long-term outcome of task-specific training based on motor relearning program (MRP) on balance, mobility and performance of activities of daily living among post-stroke patients. Methods In this two-armed randomised controlled clinical trial, a total of 66 sub-acute stroke patients who meet the trial criteria will be recruited. The patients will randomly receive task-specific training based on MRP or a conventional physical therapy program (CPT). Twenty-four physiotherapy sessions will be conducted, divided into three training sessions per week, 1 h per session, for 8 weeks, followed by an analysis of changes in patient’s balance, gait and performance of activates of daily living at three time periods; baseline, post-intervention and follow-up after 3-months, using clinical outcome measures and instrumental analysis of balance and gait. Discussion The results of this study can guide to better understanding and provide an objective clinical basis for the use of task-specific training in stroke rehabilitation. Also, it intends to help bridge the current knowledge gap in rehabilitation and training recommendations to provide a therapeutic plan in post-stroke rehabilitation.
