OBJECTIVE: To investigate the effects of two weeks of intensive mass practice with a constraint-induced movement therapy approach for the lower extremity in five chronic poststroke patients, and the persistence of effects at three and six months.

DESIGN: A single-subject experimental design (SSED) was used with an AB design and follow-ups three and six months later.

SETTING: Outpatient rehabilitation at Torsby Hospital in Sweden.

MAIN MEASURES: Motor function in lower extremity, mobility, dynamic balance, weight-bearing symmetry and walking ability were measured on six occasions during two weeks (A phase), with the Fugl-Meyer assessment for lower extremity, the Timed Up and Go, the Step Test, the Timed Walking Test and the Six-Minute Walk Test. During the intervention's B phase, six measurements were performed with the same time intervals as in the A phase. There were follow-ups three and six months later.

INTERVENTION: The intervention (B phase) consisted of bicycling, training in water, strength training, standing weight-bearing, walking up and down stairs, walking indoors and outdoors and flexibility training of the lower extremity, on all weekdays, 6 h a day for two weeks.

RESULTS: The results showed improvements in 23/30 variables (77%), 12 of them statistically significant (52%). At follow-up, 22/23 improvements persisted. For example, three of five subjects walked significantly further after the intervention and the follow-ups showed that they still walked further than before the intervention.

CONCLUSION: Intensive mass practice with constraint-induced movement therapy for the lower extremity can improve motor function, mobility, dynamic balance, weight-bearing symmetry and walking ability in chronic poststroke patients. Long-term follow-up showed that the effects persisted for these five subjects.

BACKGROUND: To regain the ability to walk is one of the most commonly stated goals for people who have had a stroke due to its importance in everyday life. Walking ability affects patients’ mobility, self-care, and social lives. Constraint-induced movement therapy (CIMT) is known to be effective in improving upper extremity outcomes post-stroke. However, there is insufficient evidence regarding its efficacy in improving lower extremity outcomes.AIM: To investigate whether a highly intensive CIMT for lower extremity (LE-CIMT) function post-stroke can improve motor function, functional mobility, and walking ability. Furthermore, it also aimed to investigate whether age, gender, stroke type, more-affected side, or time after stroke onset affect the efficacy of LE-CIMT on walking ability outcomes.

DESIGN: Longitudinal cohort study.

SETTING: Outpatient clinic in Stockholm, Sweden.

POPULATION: A total of 147 patients mean age 51 years (68% males; 57% right-sided hemiparesis), at the sub-acute or chronic phases post-stroke who had not previously undergone LE-CIMT.

METHODS: All patients received LE-CIMT for 6 hours per day over 2 weeks. The Fugl-Meyer Assessment (FMA) of the lower extremity, Timed Up and Go (TUG) test, Ten-Meter Walk Test (10MWT), and six-Minute Walk Test (6MWT) were used to assess functional outcomes before and directly after the 2-week treatment was complete as well at 3-month post-intervention.

RESULTS: Compared to baseline values, FMA (P<0.001), TUG (P<0.001), 10MWT (P<0.001) and 6MWT (P<0.001) scores were statistically significantly improved directly after the LE-CIMT intervention. These improvements persisted at the 3-month post-intervention follow-up. Those who completed the intervention 1-6 months after stroke onset had statistically significant larger improvements in 10MWT compared to those who received the intervention later than 6 months after stroke onset. Age, gender, stroke type, and more-affected side did not impact 10MWT results.

CONCLUSIONS: In an outpatient clinic setting, high-intensity LE-CIMT statistically significant improved motor function, functional mobility, and walking ability in middle-aged patients in the sub-acute and chronic post-stroke phases. However, studies with more robust designs need to be conducted to deepen the understanding of the efficacy of LE-CIMT.

CLINICAL REHABILITATION IMPACT: High-intensity LE-CIMT may be a feasible and useful treatment option in outpatient clinics to improve post-stroke walking ability.

Rehabilitation after stroke has changed and more studies with intensive therapy have been conducted. When a new method – here lower-limb constraint-induced movement therapy (CIMT) – is introduced, it is important to investigate participants’ own experience of the therapy. The present purpose was accordingly to describe stroke patients’ experience of training with lower-limb CIMT. Qualitative interviews with seven stroke patients who had participated in lower-limb CIMT were conducted. The interviews were transcribed verbatim and analysed with qualitative content analysis. One theme, knowledge of myself and my prospects for leading an easier life, emerged. Two main categories were found: the therapy and me and my body, with four and three categories respectively. The therapy comprised the informants’ experience of preparation for CIMT, the actual intensive training and its effects, and their views on the physiotherapists involved. Me and my body comprised the informants’ reflections on their own significance for the therapy, how the reflections had affected them and what insight into their condition CIMT had given. The informants reported that CIMT for the lower extremity gave them knowledge of their body and their prospects for leading an easier life. The intensive training instilled hope, since the functional improvements showed the possibilities of improvements, increasing the respondents’ independence and self-esteem. Even though the intensive training is tough, it was experienced as entirely necessary.
