Objective: Post-stroke patients must be early and frequent out-of-bed mobilised in order to improve recovery and prevent medical complications. However, evidence-based data for the optimal pivot transfer technique is missing. The objective of this study is to investigate whether there are differences in quadriceps muscle activity, weightloading and patient experiences during two different pivot transfers in subacute stroke patients.
Methods: In a randomised controlled pilot study, six stroke patients (median age 56 (54-62) years, 8 (7-11) days post-stroke) participated. Each participant performed six pivot transfers (three each over the paretic and the nonparetic lower-extremity), assisted by a physiotherapist. Surface Electromyography, Pedar-X System and Patient Experiences Form measured the outcomes.
Results: The mean quadriceps muscle activity (peak) is for rectus femoris 165.39 (55.64) mV vs. 99.38 (55.64) mV, p=0.35; vastus lateralis 235.08 (72.96) mV vs. 174.13 (77.62) mV, p=0.15; vastus medialis 234.35 (86.92) mV vs. 605.80 (457.12) mV, p=0.37 comparing the paretic with the non-paretic lower-extremity. The mean weightloading is 242.25 (89.08) Newton vs. 500.23 (71.05) Newton, p=0.63 comparing the paretic with non-paretic lowerextremity. The participants felt significantly safer (median score 1, (IQR 1-1) vs. median score 4; (IQR 4-4), p<0.01) and preferred pivot transfers over the non-paretic lower-extremity compare to the paretic lower-extremity (median score 1, (IQR 1-1) vs. median score 4, (IQR 4-4); p<0.01).
Conclusion: For the first time, we have evidence-based data for pivot transfers in subacute stroke patients. The results of quadriceps muscle activity and weight-loading indicate no statistically significant differences, while the participants are feeling significantly safer and prefer transfers over the non-paretic lower-extremity.
