Résumé : Context: Spontaneous falls and motor dependence are frequent problems among elderly living in establishment. The objective of this study is to determine the risk of falling and functional mobility in elderly people in institutions as well as the benefits of a rehabilitation program.Methods: Cross-sectional, interventional study including 72 subjects aged between 69 and 84 years residing in hospices for the elderlies. All benefited from a balanced feed. The intervention group included 40 subjects who also completed a functional rehabilitation program for 6 months, while the control group included 32 subjects who did not having benefited a functional rehabilitation program. The Morse Fall Scale (MFS) and the Timed Up and Go-test (TUG) were used to assess fall risk and mobility, Student's T-test was used to compare the two groups.Results: The risk of falling was very high, mean MFS: 90.7±8.73 points, interesting all Elderly, range: [60-130 points]. Their level of autonomy was very low, TUG: 74.15±26.44 seconds, [35-145 seconds]. By comparing the intervention group and the control group: at the first assessment, there was no difference concerning the risk of falling (MFS: 91.25±9.33 vs. 90.15±8.12 points; p=0.2) and their motor autonomy levels were also similar (TUG: 74.45±25.53 vs. 73.85±27.34 seconds; p=0.6). After applying the rehabilitation program, the intervention group observed a reduction in the risk of falling (MFS: 54.25±6.2 vs 85.21±7.9 points; p<0.001) with improvement in the level of autonomy (TUG: 45.97±11.7 vs 69.12±20.38 seconds; p<0.01). Conclusion: Conclusion: The risk of falling, mobility and balance problems are major challenges for elderlies in Kinshasa institutions, they are reducible by dint of a functional rehabilitation program supported by a balanced feed.
