Effectiveness of a Post-Acute-Care Rehabilitation Program in Patients with Stroke: A Retrospective Cohort Study.

Early rehabilitation is essential for restoring functional recovery in patients with stroke, particularly during the early phase of post-acute care (PAC), or the subacute stage. We aimed to evaluate the effectiveness of a 7-week PAC rehabilitation program in improving muscle strength, physical performance, and functional recovery. A total of 219 inpatients with stroke in the subacute stage were initially recruited from the PAC ward of a regional teaching hospital in Northern Taiwan, with 79 eligible patients-within 1 month of an acute stroke-included in the analysis. The program was delivered 5 days per week, with 3-4 sessions daily (20-30 min each, up to 120 min daily), comprising physical, occupational, and speech-language therapies. Sociodemographic data, muscle strength, physical performance (Berg Balance Scale [BBS], gait speed, and 6-minute walk test [6MWT]), and functional recovery (modified Rankin Scale [mRS], Barthel Index [BI], Instrumental Activities of Daily Living [IADL], and Fugl-Meyer assessment: sensory and upper extremity) were collected at baseline, 3 weeks, and 7 weeks. Generalized estimating equations analyzed program effectiveness. Among the 56 patients (70.9%) who completed the program, significant improvements were observed in the muscle strength of both the affected upper (B = 0.93, < 0.001) and lower limbs (B = 0.88, < 0.001), as well as in their corresponding unaffected limbs; in physical performance, including balance (BBS score: B = 9.70, = 0.003) and gait speed (B = 0.23, = 0.024); and in functional recovery, including BI (B = 19.5, < 0.001), IADL (B = 1.48, < 0.001), and mRS (B = -0.13, = 0.028). These findings highlight the 7-week PAC rehabilitation program as an effective strategy during the critical recovery phase for patients with stroke.
