In Community Dwelling Females Age 65 or Older, Gait Speed Declines as Kinesthetic Awareness of the Lower Legs Decreases

Purpose: This study investigates the existence of a correlation between the gait speed and kinesthetic sense in lower legs and to conduct further analysis of kinesthetic sense in relation to the risk of fall among community dwelling females aged 65 years or older. Materials and Methods: A non-experimental correlational, descriptive, and cohort study included 38 community dwelling females (average age of 82.5 years). The kinesthetic ruler (K-Ruler) and kinesthetic test protocol were created and used to assess lower extremity kinesthetic awareness. The GaitRite System was used to assess gait speed. Each subject was categorized into four groups: “LL” (Low K-Score and low gait speed), “LH” (Low K-Score and high gait speed), “HL” (High K-Score and low gait speed), and “HH” (High K-Score and high gait speed) according to kinesthetic awareness and gait speed measured. Voluntary fall incidence reporting over the 6-month period was followed by the initial data collection. Results: Pearson product-moment correlation (2-tailed) showed that there is a statistically significant, positive moderate-to-strong correlation between K-score and gait speed (ICC = 0.692, p Discussion: Gait speed declines as kinesthetic awareness of lower extremity decreases in community dwelling 65 or older female subjects. Additionally, the combination of kinesthetic awareness and gait speed can be served as a predictor of fall risk. The K-ruler can be used to assess lower extremity kinesthetic awareness in older people as a feasible and standard test.

The Effect of Sensory Stimulation versus Motor Control Cueing of the Foot on Balance in Elderly Females: Single Group Pretest-Posttest Study

Study Design: A Quasi Experimental Single Group Pre-Test Post-Test. Objectives: The aim of this study was to determine the effects of sensory stimulation and motor control cueing of the foot on balance in females over the age of 65. Background: Balance deficits in the elderly population have shown to have detrimental consequences. Evidence suggests that sensory stimulation and motor control of the foot improve postural sway, however, studies have yet to compare the effects of both interventions on balance. Method and Measures: A total of 40 participants were contacted to complete the study with 32 participants meeting inclusion criteria for data collection and completing the research study. Two data collection days were utilized to perform pre and post-test outcome measures using the Functional Reach Test and Overall Sway Index (collected using the Biodex Medical System Inc., Biodex Biosway Portable Balance System). The interventions were 2-minute sensory stimulation to the sole of each foot on day one, and the “short foot” motor control cue on day two. Four related sample T-tests were conducted with the interventions as the dependent variable and the time of observation (pre and post) as the independent variable. Results: The results revealed sensory stimulation significantly improved balance as indicated by a decline in postural sway from pretest (5.92 ± 3.05) to posttest (5.00 ± 2.92) (p = 0.045) and a significant increase in Functional Reach from pretest (8.01 ± 2.55) to posttest (8.70 ± 2.66) (p Conclusion: Based on the results, researchers concluded that sensory stimulation is a viable intervention to utilize in order to improve balance in the elderly population. Further research to identify the appropriate prescription of sensory stimulation to maximize effects should be completed.
