RESUMEN
BACKGROUND: Botulinum toxin (BT) injection is a new treatment for spasticity with hemiplegia after stroke. How a patient decides to receive BT injections after becoming aware of the treatment remains unclear. In this exploratory qualitative study, we aimed to investigate patients' decision-making about treatment strategies in collaboration with family and health professionals and to identify conflicts in patients' feelings about BT treatment. METHODS: The study included six patients with stroke sequelae. Data were collected using comprehensive interviews and were analyzed using the grounded theory approach and trajectory equifinality modeling. RESULTS: After patients learned about BT treatment, they clearly exhibited the following two concurrent perceptions: "the restriction of one's life due to disabilities" and "the ability to do certain things despite one's disabilities." Some patients reported a "fear of not being able to maintain the status quo owing to the side effects of BT." To alleviate this fear, timely support from family members was offered, and patients overcame anxiety through creative thinking. However, there were also expressions that revealed patients' difficulties dealing with negative events. These factors influenced the patients' development of "expectations of BT" or "hesitations about BT." CONCLUSIONS: To establish treatment strategies in collaboration with patients, healthcare professionals should show supportive attitudes and have discussions with patients and their family members to help patients resolve their conflicts and should establish treatment strategies that maintain the positive aspects of patients' lives.

BACKGROUND: Toe flexor strength is important for preventing older adults from falling. Although intrinsic foot muscles are the main determinants of toe flexor strength, exercises for strengthening these muscles are difficult for older adults. This study therefore aimed to determine whether the use of electromyographic biofeedback helps older adults to perform intrinsic foot muscle strengthening exercises. METHODS: This randomized controlled trial had two parallel arms. Participants were randomly allocated to the control group or the electromyographic biofeedback group. Control participants performed two progressive intrinsic foot muscle strengthening exercises twice a week for 6 weeks. Participants in the other group performed these exercises assisted by electromyographic biofeedback. Primary outcome measures were changes in toe flexor strength and the timed up-and-go and functional reach tests (the latter two being balance tests). FINDINGS: Altogether, 23 older adults were randomized to the control group (n = 12) or the electromyographic biofeedback group (n = 11). After the 6-week intervention, toe flexor strength on the dominant side increased in both groups (P < 0.017). However, toe flexor strength on the nondominant side increased only in the electromyographic biofeedback group (P < 0.017), with a large effect size of 1.5. There were no changes in the two balance tests. Three of the control group and two of the electromyographic biofeedback group were lost to follow- up. INTERPRETATION: Our results indicate that, the use of electromyographic biofeedback can enhance the effect of intrinsic foot muscle strengthening exercises on the nondominant side in older adults. CLINICAL TRIAL REGISTRATION NUMBER: UMIN000036521.

BACKGROUND AND PURPOSE: The associations between leg length discrepancy (LLD) and patient-perceived inequality and functional outcomes after total hip arthroplasty (THA) are unclear in the literature. The aim of this study was to determine the types of LLD after THA and to identify the best predictor of patient-perceived LLD and functional outcome in the short term after THA. METHODS: We subdivided LLD into true and apparent types and prospectively studied 53 consecutive patients undergoing unilateral primary THA to determine whether there is an association between the type of LLD and functional outcome 2 months after the operation. Apparent LLD was measured by the block test and true LLD was measured by hip radiography. We classified the patients into 4 groups: true, apparent, mixed, and no-LLD groups. The questionnaire included a visual analog scale of pain, the Western Ontario and McMaster Universities Osteoarthritis Index, and patient-perceived inequality. Physical performance was measured using walking speed and the Timed Up and Go test. RESULTS: The apparent and mixed LLD groups had a higher prevalence of patient-perceived inequality than the true and no-LLD groups. The results of physical performance showed that the walking speed of the mixed LLD group and the results of the Timed Up and Go Test of the apparent LLD group were significantly slower than those of the true LLD group. DISCUSSION: We suggested that the true LLD group may have a weak relationship with functional outcome after THA while the apparent LLD resulting from pelvic obliquity due to hip contracture or scoliosis is correlated with the short-term functional outcome after THA. CONCLUSION: Apparent LLD can be a better predictor of patient-perceived inequality and physical performance than true LLD.
