To investigate the effects of adjuvant mental practice (MP) on affected upper limb function following a stroke using three-dimensional (3D) motion analysis.
In this AB/BA crossover study, we studied 10 hemiplegic patients who had a stroke within the past 6 months. The patients were randomly allocated to two groups: one group received MP combined with conventional rehabilitation therapy for the first 3 weeks followed by conventional rehabilitation therapy alone for the final 3 weeks; the other group received the same therapy but in reverse order. The MP tasks included drinking from a cup and opening a door. MP was individually administered for 20 minutes, 3 days a week for 3 weeks. To assess the tasks, we used 3D motion analysis and three additional tests: the Fugl-Meyer Assessment of the upper extremity (FMA-UE) and the motor activity logs for amount of use (MAL-AOU) and quality of movement (MAL-QOM). Assessments were performed immediately before treatment (T0), 3 weeks into treatment (T1), and 6 weeks into treatment (T2).
Based on the results of the 3D motion analysis and the FMA-UE index (p=0.106), the MAL-AOU scale (p=0.092), and MAL-QOM scale (p=0.273), adjuvant MP did not result in significant improvements.
Adjuvant MP had no significant effect on upper limb function following a stroke, according to 3D motion analysis and three clinical assessment tools (the FMA-UE index and the two MAL scales). The importance of this study is its use of objective 3D motion analysis to evaluate the effects of MP. Further studies will be needed to validate these findings.

To determine the associating factors of fear of falling (FOF) and the correlations between FOF and quality of life (QOL) on subacute stroke patients in Korea.
Fifty hemiplegic subacute stroke patients in our clinic were recruited. We directly asked patients with their fear of falling and interviewed them with the Korean version of falls efficacy scale-international (KFES-I). We divided the participants into two groups; with FOF and without FOF. We compared these groups with the strength of hemiplegic hip abductor, knee extensor, ankle plantar flexor, functional ambulation category (FAC) scale, stroke specific quality of life (SSQOL), and hospital anxiety depression scale (HADS).
Thirty-four participants were enrolled, and more than half of the patients with subacute stroke had FOF. We compared the patients with and without FOF. According to the results, FOF was associated with the strength of hemiplegic hip abductor, knee extensor and ankle plantar flexor, FAC, total SSQOL, and domains (energy, mobility, self care, upper extremity function) of SSQOL (p<0.05). FOF was also associated with the anxiety score of HADS (p<0.05). KFES-I had a significant negative correlation with the strength of hemiplegic hip abductor, knee extensor and ankle plantar flexor, FAC, total SSQOL, and domains (energy, mobility, self care, upper extremity function) of SSQOL (p<0.01).
The FOF was associated with not only QOL but also with the physical and psychological factors, and in particular, anxiety. Therefore, further concerns about FOF in subacute stroke patients might be required.

To verify the influence of sour taste on swallowing and the presence of reflex cough when sour material was swallowed in patients with dysphagia secondary to brain injury.
Fifty dysphagic brain injury patients who underwent videofluoroscopic swallowing study (VFSS) were recruited. The patients who had shown severe aspiration at 2 ml of liquid were excluded. The dysphagic patients were given 5 ml each of a sour tasting liquid (SOUR) and a thin liquid barium (LIQUID) in random order. An expert analyzed the result of VFSS by reviewing recorded videotapes. Analysis components consisted of the Penetration-Aspiration-Scale (PAS) score, oral transit time (OTT), pharyngeal transit time (PTT), pharyngeal delay time (PDT) and the reflex cough presence.
The PAS score for SOUR was significantly lower than the one for LIQUID (p=0.03). The mean OTT for SOUR was significantly shortened compared to that for LIQUID (p=0.03). The mean PTT and PDT were also shortened in SOUR, although the differences were not statistically significant (p=0.26 and p=0.32, respectively). There was no significant difference between SOUR and LIQUID regarding the presence of reflex cough (p=1.00).
The sour taste could enhance sensorimotor feedback in the oropharynx, thus lowering the chances of penetration-aspiration caused by shortening of the oropharyngeal passage times. There was no significant difference in the presence of reflex cough produced between LIQUID and SOUR.
