Abstract
Introduction:
Having a therapist observe patients engaged in Robotic Upper Limb
Therapy (RULT) is considered inefficient use of a therapist’s time and
skill. We therefore assessed the feasibility of (RULT) administered by a
trained volunteer.
Methods: The
Volunteer had two 30-minute training sessions by an Occupational
Therapist (OT) rehearsing the MIT-Manus Planar Upper Limb Robotic
software applications, proper positioning of the patient, and device
shut-off and safety considerations. Initial patient sessions were
supervised by the patient’s OT until the Volunteer demonstrated
satisfactory performance. Inpatients on a Stroke Rehabilitation Unit
were referred by their OT for RULT if they could initiate horizontal
gravity-eliminated movement of the forearm and could follow one step
commands. They were enrolled in 25 minute (RULT) sessions based upon the
Volunteer’s availability from one to three half-days per week.
Functional Independence Measures and Fugl-Meyer Scores were recorded at
the time of Stroke Unit Admission by the OT unaware of (RULT) score
results. Statistical analyses were performed using SPSS version 11.5 and
significance was attributed if p<0.05 using 2-tailed analyses.
Results:
A total of 28 patients were enrolled in (RULT) but 2 were unable to
participate due to pain in the affected upper limb. Participants had a
mean of 3 ± 1.5 SD treatments each. Both the patients and volunteer
considered their involvement in the program as worthwhile and
meaningful. Admission MIT-Manus Adaptive-3 treatment software data
showed that the Normalized Jerk+Line+Target (Norm JLT) Score [defined as
(Jerk Score/237)+(Deviation from a Straight Line/13)+(Target Distance
Error/14)] demonstrated a significant Spearman-rho Correlation with
admission Functional Independence Measure (FIM) upper dressing r = -0.56
p=.003; and FIM grooming subscores r = -0.415, p=.035. The Norm JLT
score also predicted change in Fugl-Meyer Upper Limb scores from
admission to discharge r = - .788, p = 0.000.
Conclusions:
Robotic Upper Limb Therapy by a trained Volunteer on an inpatient
Stroke Rehabilitation Unit is easily administered, is viewed by the
patients and volunteer as rewarding, and provides objective measures
useful for assessing upper limb function and outcome. But no mention of recovery results using this.
