This study was performed to determine whether Japan Knee Osteoarthritis Measure (JKOM) in patients with knee osteoarthritis improves after walking using knee adduction-reducing shoes we devised for 1 month. The subjects consisted of20patients with knee osteoarthritis (all female, aged 63.8±7.1 years). We assessed knee pain using the visual analogue scale (VAS) and patient-oriented QOL using JKOM. To evaluate the effects of the intervention, a baseline period (A) and a subsequent intervention period (B) were established, and measurement values were compared between the two periods (AB design). Knee pain and JKOM total score and subscale of “Pain and Stiffness in knee”significantly decreased after the 1-month intervention period (B) using adduction-reducing shoes compared with values after the 1-month control period using general sneakers (A). The results of this study suggest that knee adduction-reducing shoes are useful for reducing knee pain and improving patient-oriented QOL in patients with osteoarthritis.
[Purpose] Investigate whether the purpose of this study can distinguish fall by EC-FRT (the functional reach test with eyes closed) [Subjects] Subjects were 101 local elderly residents who are not certified as being in need of care. [Methods] The EC-FRT and FRT scores were measured, and the history of falls in the past year was investigated. [Results] The EC-FRT score decreased with age. It was also lower in a group with than without fall experiences. The risk of falls was higher when the EC-FRT score was below 25.5
[Purpose] The purpose of the present study was to analyze factors for community-contained acute care hospitals that affect the total length of stay in acute care and rehabilitation hospitals among patients with proximal hip fractures. [Patients] Three hundred and thirty two patients undergoing surgery for proximal hip fractures were recruited. [Methods] Using the median value of the total length of stay, we classified the patients into two groups: a short-term group and long-term group. We retrospectively analyzed factors at the time of transfer from acute care hospitals to rehabilitation hospitals.
In this study, 143 elderly people requiring nursing care were enrolled in order to investigate the main factors affecting the 50 m round walking test. Our methodology included analysis of the relationships between upper/lower limb strength, the30second chair stand test (CS-30),the functional reach test (FRT), the one-leg standing test, and the 50 m round walking test. The main factors showing significant correlation with the 50 m round walking test in order of descending correlation coefficients were: CS-30 (r=0.48),FRT (r=0.40),quadriceps strength (r=0.23), one-leg standing test (r=0.20), and grip strength (r=0.17).Based on the results of a stepwise multiple regression analysis, CS-30 (β=0.39) and FRT (β=0.28) were selected as the main factors affecting the 50 m round walking test. The abovementioned results suggest that muscular endurance and dynamic balance exert a greater impact on the 50 m round walking test than upper/lower limb strength and static balance.
The purpose of this study was to analyze the kinematics of the Balance Walk ing Test to measure the time needed to walk slowly along a 20-cm wide and 5-m long course without deviating from it. The activities of the rectus femoris, long head of the bi ceps femoris, tibialis anterior, and medial head of the gastrocnemius, in addition to gait pa rameters, were measured during gait using a surface electromyograph and gait analysis device, respectively, involving 16 healthy adult females. The balance walking, which sub jects walk as slowly as possible, significantly increased the gait velocity and durations of the stance, double support, and swing phases, and significantly degreased the step and stride lengths and cadence against normal speed walking. Concerning muscle activity, the balance walking significantly increased the muscle activity of rectus femoris, long head of the biceps femoris, tibialis anterior, and medial head of the gastrocnemius muscle during the stance phase against normal speed walking. These results support the usefulness of this test in various settings, as it does not require specific devices or areas, and allows sim ple testing procedures.
[Objective] To confirm the significance of hand grip strength measurementfor infants, the hand grip strength of children aged 5-6 was measured and comparedwithvalues representing other motor skills. [Subjects] The measurement involved 408 (211 males and 197 females) healthy children aged 5-6. [Methods] After measuring the height, weight,and hand grip strength, the 5 motor skill tests for infants developed by the Ministry of Education, Culture, Sports, Science, and Technology were conducted to analyze their relationships with the hand grip strength. [Results] Malesʼand femalesʼmean hand grip strengths were 8.5 ± 2.2 and 8.1 ± 2.2 kg, but, sex difference was small. Single correlation analysis revealed small correlations of the hand grip strength with the height, body, and results of the following tests: 25-meter run, standing broad jump, and body support time.
