Efficacy and feasibility of SENSory relearning of the UPPer limb (SENSUPP) in people with chronic stroke: A pilot randomized controlled trial

Feasibility and efficacy of an early sensory-motor rehabilitation program on hand function in patients with stroke: a pilot, single-subject experimental design

OBJECTIVE

Hand and upper limb functional impairments following stroke lead to limitations in performing activities of daily living. We aimed to investigate feasibility and efficacy of an early sensory-motor rehabilitation program on hand and upper limb function in patients with acute stroke.

DESIGN

A pilot, single-subject experimental, A-B-A study.

SETTING

Stroke unit of an educational hospital and an outpatient occupational therapy clinic.

PARTICIPANTS

A convenience sample including five people with acute stroke.

PROCEDURES

Participants received 3 h of an intensive hand and upper limb sensory and motor rehabilitation program, 5 days per week for 3 months (15-min mental imagery, 15-min action observation, 30-min mirror therapy, 1.5-h constraint-induced movement therapy, and 30-min bilateral arm training). Activities were chosen based on the task-oriented occupational therapy approach.

OUTCOME MEASURES

An assessor blinded to intervention program measured sensory and motor functions using action research arm test, box and block test, Semmes-Weinstein monofilaments, and upper extremity section of Fugl-Meyer assessment.

RESULTS

Assessment data points in intervention and follow-up phases compared to baseline were in higher levels, sloped upwardly, and increased significantly for all participants in all outcome measures.

CONCLUSIONS

The present pilot study showed that a package of nowadays evidence-based rehabilitation methods including mental imagery, action observation, mirror therapy, modified constraint-induced movement therapy, bilateral arm training, and task-oriented occupational therapy approach is able to improve sensory and motor functions of the hand and upper limb in patients with acute stroke.

Experiences of SENSory Relearning of the UPPer Limb (SENSUPP) after Stroke and Perceived Effects: A Qualitative Study

Recently, it was shown that sensory relearning of the upper limb (SENSUPP) is a promising intervention to improve sensorimotor function after stroke. There is limited knowledge, however, of how participants perceive the training. Here, we explored how persons with sensory impairments in the upper limb experienced the SENSUPP protocol (combined sensory- and motor training and home exercises for 5 weeks) and its effect. Fifteen persons (mean age 59 years; 10 men; >6 months post-stroke) were individually interviewed, and data were analyzed with qualitative content analysis. An overall theme ‘Sensory relearning was meaningful and led to improved ability to perform daily hand activities’ and two categories with six subcategories emerged. The outpatient training was perceived as meaningful, although the exercises were demanding and required concentration. Support from the therapist was helpful and training in small groups appreciated. The home training was challenging due to lack of support, time, and motivation. Small improvements in sensory function were perceived, whereas increased movement control and ability in performing daily hand activities were reported. In conclusion, the SENSUPP protocol is meaningful and beneficial in improving the functioning of the UL in chronic stroke. Improving compliance to the home training, regular follow-ups, and an exercise diary are recommended.
