The purpose of this study was to examine whether lower extremity progressive resistance training (PRT) in older adults who are at risk for falls improves balance confidence. The study was a one-group pretest-posttest quasi experimental design. The variables of interest (dependent) were balance confidence and muscular strength. Subjects were volunteers recruited from Bentley Village. The measurements used for the dependent variables included the Activities-specific Balance Confidence (ABC)...

The study was a one-group pretest-posttest quasi experimental design. The variables of interest (dependent) were balance confidence and muscular strength. Subjects were volunteers recruited from Bentley Village. The measurements used for the dependent variables included the Activities-specific Balance Confidence (ABC) Scale and a predicted one repetition maximum (1 RM) from a 5RM test. The independent variable was high-intensity PRT for the lower extremities. Subjects performed PRT three times a week for 10 weeks for a total of 30 training sessions. All subjects demonstrated statistically significant increases in lower extremity strength and improvements in balance confidence, however, statistically a correlation could not be made between increased lower extremity strength and improvements in balance confidence. There were positive correlations seen between lower extremity strength and attendance. In conclusion, seven balance impaired active older adults between the ages of 80 and 90 years of age completed a 1 0-week high intensity PRT program for the LE. High-intensity PRT is a safe and effective means of increasing strength in the older adult. Future studies need to be completed to determine if high intensity PRT may also improve balance confidence in older adults.

Background. Individuals with Parkinson’s Disease (PD) experience a progressive deterioration in the performance of learned, repetitive movement sequences which affects his or her ability to perform activities of daily living. Individuals with PD can maintain daily functional activities longer by remaining as active as possible. Documenting physical activity in this population will identify functional activities that can be performed at varying stages of this progressive neurological disease....
Show moreBackground. Individuals with Parkinson’s Disease (PD) experience a progressive deterioration in the performance of learned, repetitive movement sequences which affects his or her ability to perform activities of daily living. Individuals with PD can maintain daily functional activities longer by remaining as active as possible. Documenting physical activity in this population will identify functional activities that can be performed at varying stages of this progressive neurological disease. Objective. The purpose of the study was to determine the relationship of energy expenditure physical activity in individuals affected by PD at different severity stages Design. This was a quantitative, non-experimental descriptive study. Data were collected in four Florida cities: Naples, Fort Myers, Tampa, and Fort Lauderdale. Participants. The participants consisted of 30 individuals with PD (Hoehn & Yahr stages 1-5). Methods. Participants best matched his or her disabilities to one of the seven descriptions corresponding to the Modified Hoehn & Yahr (H&Y) Staging Scale. As a comparison tool, investigators used the Modified H&Y Staging Scale to determine the severity stage of each participant. Next, participants completed the MET Activity Table to indicate which activities he or she could complete independently on a daily basis. Each participant’s demographical data were also collected. Results. The Pearson Correlation Coefficient demonstrated an inverse relationship between the Modified H&Y scores and MET activity level with r= -0.440 (p= 0.015). Results from a multiple regression analysis found three variables to be good predictors of MET activity level: investigators’ determination of the participant’s Modified H&Y score (p=0.018), participant’s age (0.048), and participant’s age of diagnosis (0.020). The coefficient of determination for the multiple regression analysis was r2=0.428. However, gender, whether the participant lived alone, and whether the participant required a caregiver’s assistance were not statistically significant predictors of MET activity level for individuals with PD. Limitations. Data were obtained from a limited number of participants and included few participants in Modified H&Y stages 1 and 5. This research used a list of descriptions corresponding to the Modified H&Y Staging Scale that are not currently a standardized scale of measure. Lastly, investigators acknowledged that use of participants’ self-reporting of his or her current physical activity level is a limitation of this study. Conclusions. As individuals with PD increase in disease severity stage, his or her energy expenditure during physical activity is predicted to decrease. This study can be used as a positive motivational tool for individuals with PD. Individuals can strive to meet or maintain the mean activity level of his or her current PD stage. Results of this study are promising; however, studies with larger samples are needed.
