PENGARUH LATIHAN ISOMETRIK DENGAN HANDGRIP MODIFIKASI (ReHand-Stroke) TERHADAP TEKANAN DARAH DAN KEKUATAN OTOT PASIEN PASCA STROKE DI PUSKESMAS
Yuliyanti Permane Suci1, Endang Triyanto2, Desiyani Nani3

Latar Belakang: Hemiparese dan instabilitas tekanan darah pada pasien pascastroke menghambat pemulihan. Inovasi alat ReHand-Stroke dikembangkan untuk memberikan indikator agar latihan isometrik handgrip lebih terukur sesuai dosis.
Tujuan: Mengembangkan alat ReHand-Stroke dan menganalisis pengaruhnya terhadap tekanan darah serta kekuatan otot pasien pascastroke.
Metode: Penelitian Tahap I menggunakan Research and Development (R&D) dengan pengembangan prototype modifikasi pegas (2-10 kg) serta sensor lampu dan bunyi. Tahap II menggunakan desain Quasi-Experimental (Pretest-Posttest Control Group) pada 60 partisipan yang dibagi menjadi kelompok intervensi (n=30) dan kontrol (n=30). Kelompok intervensi berlatih dengan ReHand-Stroke dan kelompok kontrol menggunakan bola karet standar selama 6 minggu (5 menit/sesi, 6x seminggu). Data dianalisis menggunakan uji Wilcoxon dan Mann-Whitney.
Hasil: ReHand-Stroke dinyatakan valid dengan nilai S-CVI 0,93. Analisis data pada masing-masing kelompok menunjukkan perbedaan signifikan antara nilai pre-test dan post-test pada variabel kekuatan otot serta tekanan darah (p < 0,05). Selanjutnya, hasil perbandingan antar kelompok menunjukkan perbedaan signifikan antara kelompok intervensi dan kelompok kontrol pada pengukuran akhir (p = 0,001). Kelompok intervensi menunjukkan perubahan lebih besar dengan selisih median peningkatan kekuatan otot sebesar 7 kg, serta penurunan tekanan darah sistolik 20,5 mmHg dan diastolik 12 mmHg.
Kesimpulan: Latihan isometrik menggunakan ReHand-Stroke selama 6 minggu efektif menurunkan tekanan darah dan meningkatkan kekuatan otot. Alat ini layak digunakan sebagai media rehabilitasi mandiri di layanan kesehatan primer dengan pemantauan tanda-tanda vital secara ketat.

THE EFFECT OF ISOMETRIC EXERCISE WITH MODIFIED (ReHand-Stroke)  ON BLOOD PRESSURE AND MUSCLE STRENGTH OF POST-STROKE PATIENTS AT PUBLIC HEALTH CENTERS
Yuliyanti Permane Suci1, Endang Triyanto2, Desiyani Nani3
Background: Hemiparesis and blood pressure instability in post-stroke patients hinder recovery. The ReHand-Stroke innovation was developed to provide indicators so that isometric handgrip exercises are more measurable according to the dosage.
Objective: To develop the ReHand-Stroke device and analyze its effect on blood pressure and muscle strength in post-stroke patients.
Methods: Phase I utilized Research and Development (R&D) to develop a prototype with spring modifications (2-10 kg) and light and sound sensors. Phase II employed a Quasi-Experimental design (Pretest-Posttest Control Group) with 60 participants divided into intervention (n=30) and control groups (n=30). The intervention group practiced with ReHand-Stroke, while the control group used standard rubber balls for 6 weeks (5 minutes/session, 6x per week). Data were analyzed using Wilcoxon and Mann-Whitney tests.
Results: ReHand-Stroke was declared valid with an S-CVI value of 0.93. Data analysis in each group showed significant differences between pre-test and post-test values in muscle strength and blood pressure (p < 0.05). Furthermore, the inter-group comparison showed a significant difference between the intervention and control groups at the final measurement (p = 0.001). The intervention group showed greater changes with a median difference in muscle strength increase of 7 kg, and a decrease in systolic blood pressure of 20.5 mmHg and diastolic of 12 mmHg.
Conclusion: ReHand-Stroke was effective in increasing muscle strength and reducing blood pressure in post-stroke patients at week 6. This device is feasible for use as a self-rehabilitation medium in primary healthcare services with strict monitoring of vital signs.
Keywords: Blood Pressure, Isometric Handgrip, Muscle Strength, Post-Stroke, ReHand-Stroke.
