Abstract
Kaki sebagai bearing of body weight sangat berperan dalam kenyamanan daily activity. Peningkatan massa tubuh selama kehamilan berkorelasi dengan perubahan dimensi kaki yang dapat menyebabkan peningkatan beban sendi pada sistem tubuh. Peningkatan beban sendi tentu akan mempengaruhi keseimbangan postural dan keseimbangan berjalan wanita hamil yang dapat dideteksi melalui center of pressure (COP) dan kinematika ekstremitas bawah. Oleh karena itu, dirancang suatu sistem dengan menggunakan sensor tekanan FSR interlink 402 dan sensor gabungan accelerometer ADXXL335 - gyroscope ENC-03RC yang dikomputasikan oleh mikrokontroler STM32F10C8T6. Data sensor tekanan pada bagian telapak kaki: toe, first metatarsal (M1), fifth metatarsal (M5), dan heel digunakan untuk menentukan posisi dan deviasi center of pressure (COP) serta temporal parameter. Sedangkan data sensor sudut pada bagian: thigh, shank, dan foot akan digunakan untuk menentukan kinematika ekstremitas bawah yang meliputi knee joint parameter dan ankle joint parameter. Data komputasi mikrokontroler akan ditampilkan pada Personal Computer (PC) melalui komunikasi bluetooth. Pengujian dilakukan untuk mendeteksi perbedaan gaya berjalan wanita hamil dengan gaya berjalan normal. Hasil penelitian menunjukkan bahwa gaya berjalan wanita hamil dibandingkan gaya berjalan normal memiliki posisi center of pressure (COP) cenderung ke arah medial-anterior sehingga memungkinkan tren pronasi kaki dengan deviasi center of pressure yang lebih tersebar sebagai indikasi menurunnya stabilitas gaya berjalan dan peningkatan risiko jatuh. Gaya berjalan wanita hamil juga menunjukkan durasi satu siklus gait yang lebih lama dengan kecepatan gaya berjalan yang lebih kecil dibandingkan gaya berjalan normal. Kinematika ekstremitas bawah untuk gaya berjalan wanita hamil dibandingkan gaya berjalan normal menunjukkan adanya kecenderungan penurunan fleksi dan peningkatan ekstensi dari knee joint serta kecenderungan penurunan plantarfleksi dan dorsifleksi sebagai bentuk adaptasi menjaga stabilitas keseimbangan gaya berjalan. Rekomendasi berdasarkan hasil penelitian menunjukkan gaya berjalan wanita hamil lebih nyaman ketika menggunakan desain alas kaki sandal selop dibandingkan sandal jepit serta dibutuhkan bantalan penyangga pada ekstremitas bawah ketika posisi duduk/tidur.

Since human feet bear body weight, they play a crucial role in daily life activities. There is a correlation between the growth in body mass during pregnancy and changes in foot dimensions, which can increase the joint strain on the systems of the body. The center of pressure (COP) and lower extremity kinematics can identify the effects of the increase in joint load on the postural balance of pregnant women and walking balance. A system utilizing the FSR interlink 402 pressure sensor and the combined sensor accelerometer ADXXL335 - gyroscope ENC-03RC computed by the STM32F10C8T6 microcontroller is therefore offered. The position and deviation of the center of pressure (COP) as well as the walking phase of pregnant women were determined using pressure sensor data collected from the toe, first metatarsal (M1), fifth metatarsal (M5), and heel of the foot. While the angle sensor data from the thigh, shin, and foot portions will be used to identify the kinematics of the lower extremities, including the knee joint parameters and ankle joint parameters, the data computed by the microcontroller will be shown on the personal computer (PC) through Bluetooth. Normal-gait and pregnant women are subjected to tests designed to detect gait variations. Compared to a normal gait, the center of pressure (COP) position stride of pregnant women tends to be medial-anterior, allowing for a pronation trend of the foot and a more dispersed center of pressure deviation as an indicator of lower gait stability and an increased risk of falling. Additionally, the gait of pregnant women exhibited a longer time per gait cycle and slower gait speed than normal gait. As an adaptation to maintain a stable gait balance, the lower extremity kinematics of pregnant women exhibited a propensity to decrease flexion and increase extension of the knee joint, as well as a tendency to decrease plantarflexion and dorsiflexion. Recommendations based on the results of the study show that the gait of pregnant women is more comfortable when using slippers than flip-flops and requires support for the lower extremities when sitting/sleeping.
