Purpose: The aim of this quasi-experimental research was to determine the effects of exercise by using coconut shell pulley on range of motion (ROM) of shoulder joint in the elderly.

Methods: Participants were the elderly (aged 60-75), purposively recruited from 2 communities in Mueang Nonthaburi District and randomly allocated to the experimental group (n=27), who attended the 12-week exercise by using coconut shell pulleys three times a week for 15 minutes. The control group (n=27) received no intervention. Range of motion of shoulder joints were collected before and after the experiment. Independent sample t-test and paired t-test were used to compare means between the two groups and change values within-group. A p-value of 0.05 was considered significant.

Result: The results showed improvements in ROM in shoulder flexion (163.89:127.78), extension (60.19:31.85), abduction (163.33:120.56), adduction (54.63:26.48), internal rotation (89.81:87.22), and external rotation (72.41:42.59) in the experimental group, which were significantly different from those of the control group (p<.05).

Conclusion: The utilization of a coconut shell hoist for exercise training resulted in an enhancement of shoulder joint flexibility in the elderly. This approach could serve as a substitute for conventional exercises in promoting the well-being of older individuals.
