RESUMEN
OBJECTIVES: To study the addition of feedback-guided neck strength home exercise to physical therapy as an enhanced rehabilitation programme in the treatment of patients with chronic neck pain. DESIGN: A prospective randomised controlled trial. SETTING: Rehabilitation department of an academic hospital. SUBJECTS: Patients with chronic neck pain. INTERVENTIONS: The patients in both groups received supervised physical therapy sessions 3 times a week for 12 weeks. Patients in Group A (N = 38) used the neck strengthening exerciser device for 20â min daily at home for 6 weeks and patients in Group B (N = 20) performed 20â min of daily regular neck exercise at home for 6 weeks. OUTCOME MEASURES: Neck disability index, pain visual analogue scale, active range of motion of the neck, Patient Global Assessment and patient evaluation of treatment effect. All subjects were assessed at baseline as well as at 6- and 12-week follow-ups. RESULTS: At the 6-week follow-up, Group A exhibited significantly greater improvements (P < 0.05) in pain Visual Analogue Scale (Group A: 2.97 ± 1.57; Group B: 4.20 ± 1.82), neck disability index (Group A: 13.95 ± 8.07; Group B: 20.07 ± 9.14) and active cervical extension (Group A: 65.26 ± 12.76; Group B: 51.45 ± 11.78). At 12-week follow-up, Group A also exhibited significantly greater active cervical extension (Group A: 67.74 ± 11.94; Group B: 53.85 ± 14.09; P < 0.05). CONCLUSION: Adding neck strengthening exerciser home training to physical therapy was demonstrated to be more effective than physical therapy alone for patients with chronic neck pain.

AIMS: Nonmotor symptoms (NMS) such as cognitive impairment and impulse-control disorders in Parkinson's disease (PD) remain a therapeutic challenge. Transcranial direct current stimulation (tDCS) has emerged as a promising alternative, although its immediate effects on NMS have been less well defined. In this randomized, sham-controlled, crossover study, we aimed to explore the single-session tDCS effects on cognitive performance in PD. METHODS: Ten nondemented patients with PD completed two sessions in counterbalanced order, receiving 20 minutes of either 2 mA anodal or sham tDCS over the left dorsolateral prefrontal cortex (DLPFC). During stimulation, they performed the visual working memory and go/no-go tasks. Performance of the tasks was compared between the two conditions. RESULTS: Single-session anodal tDCS over the left DLPFC did not significantly improve cognitive tasks in PD compared with sham (P > .05). CONCLUSION: Single-session tDCS is ineffective in improving visual working memory and inhibitory control in PD. Further research may worth exploring alternative tDCS parameters, ideally with repeated sessions and concomitant training.

AIM: To evaluate aerobic capacity in patients with ankylosing spondylitis (AS) and determine possible relationships between aerobic capacity, pulmonary function, and disease-related variables. METHOD: Forty-two patients with AS and 42 healthy controls were recruited in the study. Descriptive data, disease-related variables (grip strength, lumbosacral mobility, occiput-to-wall distance, chest expansion, finger-to-floor distance, Bath Ankylosing Spondylitis Disease Activity Index, Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Global Score, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and hemoglobin), and chest and thoracic spine x-rays were collected in each patient with AS. All subjects took standard pulmonary function and exercise tolerance tests, and forced vital capacity (FVC) and aerobic capacity were recorded. RESULTS: Both aerobic capacity and FVC in patients with AS were significantly lower than those in normal subjects (P < 0.05). AS patients with BASFI scores of < 3 or BASDI scores of < 4 had a higher aerobic capacity. There was significant correlation between aerobic capacity, vital capacity, chest expansion, Schober's test, cervical range of motion, and BASFI in patients with AS. Neither aerobic capacity nor vital capacity correlated with disease duration, ESR, CRP, and hemoglobin. CONCLUSIONS: Significantly reduced aerobic capacity and FVC were observed in patients with AS, and there was significant correlation between aerobic capacity, vital capacity, chest expansion, and BASFI.

PURPOSE: Although ultrasound (US)-guided subacromial injection has shown increased accuracy in needle placement, whether US-guided injection produces better clinical outcome is still controversial. Therefore, this study aimed to compare the efficacy of subacromial corticosteroid injection under US guidance with palpation-guided subacromial injection in patients with chronic subacromial bursitis. METHODS: Patients with chronic subacromial bursitis were randomized to a US-guided injection group and a palpation-guided injection group. The subjects in each group were injected with a mixture of 0.5 mL dexamethasone suspension and 3 mL lidocaine into the subacromial bursa. The primary outcome measures were the visual analog scale for pain and active and passive ranges of motion of the affected shoulder. Secondary outcome measures were the Shoulder Pain and Disability Index, the Shoulder Disability Questionnaire, and the 36-item Short-Form Health Survey (SF-36). The primary outcome measures were evaluated before, immediately, 1 wk, and 1 month after the injection; the secondary outcome measures were evaluated before, 1 wk, and 1 month after the injection. RESULTS: Of the 145 subjects screened, 46 in each group completed the study. Significantly greater improvement in passive shoulder abduction and in physical functioning and vitality scores on the SF-36 were observed in the US-guided group. The pre- and postinjection within-group comparison revealed significant improvement in the visual analog scale for pain and range of motion, as well as in the Shoulder Pain and Disability Index, Shoulder Disability Questionnaire, and SF-36 scores, in both groups. CONCLUSIONS: The US-guided subacromial injection technique produced significantly greater improvements in passive shoulder abduction and in some items of the SF-36. US is effective in guiding the needle into the subacromial bursa in patients with chronic subacromial bursitis.
