ABSTRACT
Background and Purpose – Muscle weakness, particularly of lower limbs, is associated with reduced walking speed, increased risk of falls and disability in elderly. Though Progressive resisted exercises has been proved to increase muscle strength in elderly there is uncertainty about its dosage and its effect on balance, mobility and depression in elderly. The objective of the study was to know if there is any improvement in balance, mobility, depression on the Berg balance scale, Timed Up and Go test and Geriatric Depression Scales respectively after the intervention program.
Methodology- After taking ethical committee permission and informed consent from participants, 38 subjects, mean age, (71.97±4.87) years, ambulatory with or without walking aid were recruited in the study from two old age homes. The study design was within group pre-post experimental design. The study was single blinded to reduce the bias. The participants were given sub maximal (30-70% of 1 R M) Progressive resisted exercises to lower limb muscles - ankle dorsiflexors, plantar flexors, hamstrings, quadriceps, hip abductors and hip extensors with free weights (in the form of sand bags). The total duration of the study was ten weeks. ACSM guidelines for strength training were followed. The outcome measures of the study were Berg Balance Scale, Timed Up and Go test, Geriatric Depression Scale. After completion of the study, the collected data was statistically analysed.
Results- Statistical analysis was done by using paired t test for Timed Up and Go test, scores of Berg balance scale and Geriatric depression scale were analysed using Wilcoxon signed rank test. All the parameters scores on Berg balance scale (z= -5.659, p = 0.00), Timed Up and Go test (t=17.66, two tailed significance of 0.00), Geriatric depression scale (z = -5.659, p=0.00) showed significant improvement post intervention.
Conclusion - Sub maximal Progressive resisted exercises (30 to 70 % 1 RM) is an effective and safe exercise program to improve balance, mobility and depression in institutionalised elderly.
