To examine the effect of cane use and cane positions on the sit-to-stand (STS) performance of stroke patients.


In a crossover study, 30 stroke patients performed STS test in seven situations in a random sequence: without a cane, three positions with a regular cane (parallel to the ankle, parallel to the 5th toe, and 10 cm in front of the 5th toe), and the same three positions with a quad cane. The peak vertical ground reaction force (GRF) and maximum vertical cane support force during STS were recorded.


Using a cane significantly reduced the peak GRF by 3%~9% of body weight compared to that without a cane (p=0.000~0.023). Different cane positions strongly influenced the maximum cane support force and peak GRF. When the cane was closer to the ankle, the maximal cane support force increased by 6.7%~8.6% of body weight, which resulted in a decrease in the peak GRF.


Both types of cane reduced lower extremities’ load during STS. When the cane was closer to the trunk, the load on legs was lessened, while the load on the upper extremity increased. Upper extremity’s load during STS was greater when using quad cane than using regular cane.
