Exercise intervention and their respective results with PEDro scoring

References	Intervention	Results	PEDro score
Samuel et al. (2013)	First component: Brisk walking program for 15-20 min at an RPE between 3 and 5/10 for 5 days a week for 6 weeks Second component: Active exercise program for both upper and lower limbs 5 days a week for 6 weeks Progression: Active-resisted exercises for biceps, triceps, hamstrings, and quadriceps 8-10 times for 2-3 sets	Functional capacity evaluated by 6MWT showed significant improvement in the experimental group that underwent the exercise training (P<0.05) QOL also improved with exercise training as well as the PCS was maintained as much as the baseline with no significant deterioration	9
Zhao, MD et al. (2016)	Resistance program - chest press in squat, wall push up, military press, side arm raises, biceps curl, shoulder shrugs, and calf raises. Weights included dumbbells and inserts into an ankle strap Intensity: 3 sets of 8-12 repetitions of each functional resistance for 7 weeks with rest periods of 2 min Walking program: Five times for 6 min to achieve 30 min of walking each day for 7 weeks	The MPACT participants had achieved improvement in several strength, mobility, physical activity, diet, and QOL endpoints These trends were statistically significant (P<0.05) in knee strength, mental health, head-and-neck QOL, and barriers to exercise	6
Samuel et al. (2019)	Control group - three 10-min walk every 5 days a week Experimental group - aerobic exercise (brisk walking 15-20 min) and active resistance exercise: Biceps curl, triceps extension, overhead shoulder flexion, hip flexion and abduction, and quadriceps (knee extension) Intensity: RPE of 3-5/10 for 15-20 min Frequency: 5 days/week	A 11-week training program showed significant improvement in the functional capacity (P<0.001), QOL (P<0.001), and prevention of worsening of fatigue (P<0.001) in the exercise group	8
Lonkvist et al. (2017)	Resistance training: Large muscle groups Intensity and volume progression: From 2 to 3 sets with a load corresponding to 15-8 RM Frequency: 36 training sessions, i.e., thrice weekly for 12 weeks Control group: No restriction on any physical activity but no organized training	12-week resistance training showed significant improvement in muscle strength, muscle mass, body composition, and QOL. This study also proved to be safe and feasible in terms of resistance training	8

6MWT: 6-min walk test, PCS: Physical component score, QOL: Quality of life, RPE: Rating of perceived exertion, RM: Repetition maximum
