“…[9][10][11] Perbedaan ukuran lebar langkah dapat mempengaruhi keseimbangan untuk mengatur posisi Center of Mass (CoM) dan menunjukkan perbedaan gaya berjalan lansia yang memiliki risiko jatuh dan tidak. 12 Penelitian-penelitian sebelumnya lebih banyak melihat perubahan lebar langkah pada permukaan mendatar selain itu masih adanya perbedaan pendapat dari penelitian sebelumnya mengenai perubahan lebar langkah dan keseimbangan lansia saat berjalan sehingga membuat peneliti tertarik untuk meneliti lebih lanjut mengenai lebar langkah terhadap risiko jatuh dengan kondisi lingkungan yang berbeda yaitu permukaan menanjak karena lebar langkah merupakan salah satu indikator dalam keseimbangan berjalan ditambah masih kurangnya data-data yang membahas lansia yang ada dimasyarakat dalam melakukan aktivitas berjalan melewati akses-akses menanjak.…”

Pendahuluan: Semakin bertambah usia sistem dan jaringan tubuh mengalami perubahan pada sistem sensoris, motorik dan pemrosesan pusat untuk mengontrol posisi tubuh saat bergerak. Penurunan pada salah satu sistem tersebut mengakibatkan kemampuan untuk mengontrol keseimbangan menjadi berkurang. Keseimbangan diperlukan dalam melakukan aktivitas sehari-hari seperti berjalan khususnya dipermukaan menanjak. Seiring bertambahnya usia sistem sensoris untuk menerima informasi mulai menurun, jumlah serat motorik berkurang, berkurangnya sel-sel otak dan perubahan neurotransmitter pada sistem saraf pusat menghasilkan penurunan fasilitas gerakan dan kontrol motorik salah satunya mengakibatkan perubahan pada pola berjalan. Lebar langkah merupakan salah satu parameter gaya berjalan untuk melihat keseimbangan saat berjalan. Beberapa penelitian telah menyelidiki bagaimana perubahan lebar langkah lansia saat berjalan dipermukaan mendatar tetapi tujuan penelitian ini untuk mengetahui lebar langkah memengaruhi keseimbangan dinamis lansia saat berjalan menanjak. Metode: Metode yang digunakan dalam penelitian ini yaitu cross sectional dengan teknik pengambilan sampel purposive sampling. Hasil: Uji normalitas pada penelitian diperoleh nilai signifikan pada lebar langkah yaitu 0,666 dan keseimbangan diperoleh nilai 0,259. Data pengukuran berdistribusi normal karena p>0,05. Uji hipotesis pada penelitian ini menggunakan uji pearson correlation diperoleh hasil p = 0,000. Nilai p<0,05 menunjukkan adanya korelasi antara keseimbangan dinamis dan lebar langkah saat berjalan menanjak dan memiliki korelasi yang kuat 0,933 dengan nilai positif yang mengindikasikan bahwa nilai lebar langkah dan keseimbangan lansia berbanding lurus. Semakin menurun keseimbangan lansia maka terjadi pelebaran lebar langkah yang mengindikasikan risiko jatuh yang lebih saat berjalan menanjak. Simpulan: Lebar langkah berhubungan dengan keseimbangan berjalan pada lansia. Perubahan keseimbangan ketika berjalan dibidang menanjak meningkatkan risiko jatuh dengan ditandainya besarnya ukuran lebar langkah saat berjalan di permukaan menanjak. Kata Kunci: Lansia, lebar langkah, keseimbangan, permukaan menanjak

“…The number of adult and older adult women is higher than that of men in the general Brazilian population 3 It was demonstrated that women are at increased risk of more frequent tripping and falling than age-matched men 4 . However, there is lack of studies in Brazilian and international literature verifying changes in static postural balance related to the quality of therapeutic exercise performed by women in the transition between adult and older ages 5 .…”

The aging process causes changes in the physical and functional conditions, as well as in the foot structure and function. This study aimed to analyze the plantar pressure variation with respect to visual information and physical activity in adult and older women. This was a cross-sectional study that included 142 women (mean age of 67.8 years). Participants responded the anamnesis questionnaire, Mini Mental State Examination, and International Physical Activity Questionnaire. Plantar pressure was assessed using computerized baropodometry. Weight distribution was observed in semitandem positions for the right foot forward and then the left foot forward . Data analysis showed that foot type had no correlation with age (p = 0.37 right foot; p = 0.93 left foot) or level of physical activity (p = 0.28 right foot; p = 0.96 left foot). Moreover, plantar pressure variation showed no significant relationship with age (R2 = 0.2; p = 0.6). In conclusion, plantar pressure variation is not associated with the morphological foot type in women analyzed, as the visual condition did not generate plantar pressure variations when compared to its effect on the classification of plantar arches. Furthermore, level of physical activity was not associated with plantar pressure variation .

AbstractFalls are a multifactorial cause of injuries for older people. Subjects with osteoporosis are more vulnerable to falls. The focus of this study is to investigate the performance of the different machine learning models built on spatiotemporal gait parameters to predict falls particularly in subjects with osteoporosis. Spatiotemporal gait parameters and prospective registration of falls were obtained from a sample of 110 community dwelling older women with osteoporosis (age 74.3 ± 6.3) and 143 without osteoporosis (age 68.7 ± 6.8). We built four different models, Support Vector Machines, Neuronal Networks, Decision Trees, and Dynamic Bayesian Networks (DBN), for each specific set of parameters used, and compared them considering their accuracy, precision, recall and F-score to predict fall risk. The F-score value shows that DBN based models are more efficient to predict fall risk, and the best result obtained is when we use a DBN model using the experts’ variables with FSMC’s variables, mixed variables set, obtaining an accuracy of 80%, and recall of 73%. The results confirm the feasibility of computational methods to complement experts’ knowledge to predict risk of falling within a period of time as high as 12 months.
