ABSTRACT
OBJECTIVE: The present study aimed to create a shorter version of the Action Research Arm Test (ARAT) without compromising its measurement properties. DESIGN: Secondary analysis of stroke recovery cohorts that used the ARAT to measure upper limb impairment. SETTING: Rehabilitation centers. PARTICIPANTS: Patients with stroke from 5 different stroke recovery cohorts (N=1425). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: A decision tree version of the ARAT (ARAT-DT) was developed using chi-square automated interaction detection. In an independent validation subset, criterion validity, agreement of ARAT-DT with original ARAT scores and score categories, and construct validity with the Fugl-Meyer Upper Extremity Scale score were determined. RESULTS: In total, 3738 ARAT measurements were available involving 1425 subjects. Chi-square automated interaction detection analysis in the development subset (n=2803) revealed an optimized decision tree with a maximum of 4 consecutive items. In the validation data set (n=935), the ARAT-DT differed by a mean of 0.19 points (0.3% of the total scale) from the original ARAT scores (limits of agreement=-5.67 to 6.05). The ARAT-DT demonstrated excellent criterion validity with the original ARAT scores (intraclass correlation coefficient=0.99 and ρ=0.99) and scoring categories (κw=0.97). The ARAT-DT showed very good construct validity with the Fugl-Meyer Upper Extremity Scale (ρ=0.92). CONCLUSION: A decision tree version of the ARAT was developed, reducing the maximum number of items necessary for ARAT administration from 19 to 4. The scores produced by the decision tree had excellent criterion validity with original ARAT scores.

AIMS: Ulnar-sided wrist pain has historically been equated to lower-back pain of wrist surgery. Little is known about the relationship between psychosocial profile and the manifestation of ulnar-sided wrist pathology and their treatment outcomes. This study aimed to determine the impact of pain catastrophising, psychological distress, illness perception, and patients' outcome expectations on patient-reported pain and hand function before and one year after surgery for ulnar-sided wrist pathology. PATIENTS AND METHODS: We included patients who underwent surgical treatment for ulnar-sided wrist pathology. Before surgery, patients completed the Pain Catastrophising Scale (PCS), Patient Health Questionnaire (PHQ), Brief-Illness Perception Questionnaire (B-IPQ), and Credibility/Expectancy Questionnaire (CEQ). Pain and dysfunction were assessed before (n = 423) and one year after surgery (n = 253) using the Patient Rated Wrist/Hand Evaluation (PRWHE). Hierarchical linear regression was used to assess the relationship between psychosocial factors and the preoperative PRWHE score, postoperative PRWHE score, and change in PRWHE. RESULTS: Psychosocial variables explained an additional 35% of the variance in preoperative PRWHE scores and 18% on postoperative scores. A more negative psychosocial profile was associated with higher (worse) preoperative PRWHE scores (PCS: B = 0.19, CI = [0.02-0.36]; B-IPQ Consequences: B = 3.26, CI = 2.36-4.15; and B-IPQ Identity, B = 1.88 [1.09-2.67]) and postoperative PRWHE scores (PCS: B = 0.44, CI = [0.08-0.81]) but not with the change in PRWHE after surgery. Higher treatment expectations were associated with a lower (better) postoperative PRWHE score (CEQ expectancy: B = -1.63, CI = [-2.43;-0.83]) and a larger change in PRWHE scores (B =|1.62|, CI = [|0.77; 2.47|]). CONCLUSION: A more negative psychosocial profile was associated with higher pain levels and dysfunction preoperatively and postoperatively. However, these patients showed similar improvement as patients with a more feasible psychosocial profile. Therefore, patients should not be withheld from surgical treatment based on their preoperative psychosocial profile alone. Boosting treatment expectations might further improve treatment outcomes. LEVEL OF EVIDENCE: III (Cohort study).

INTRODUCTION: Osteoarthritis (OA) affects millions of people worldwide. In hand OA, the thumb base is the most affected single joint. The reported radiographic prevalence ranges from 0 to 100%, making the true radiographic prevalence unclear. Hence, we conducted a meta-analysis on the age and sex-specific prevalence of radiographic thumb base OA. METHODS: We performed a search in Embase, Medline Ovid, Web of Science Core Collection, Cochrane Central Register of Trials, and Google Scholar. We included studies of the general population that reported thumb base OA for males and females separately based on a hand radiograph and reported the age of these groups. Using meta-regression, we estimated the odds ratio (OR) of having radiographic thumb base OA for age and sex, while adjusting for within-study correlation. RESULTS: The initial search yielded 4,278 articles; we finally included 16 studies that reported the age- and sex-stratified prevalence. Taken together, there were 104 age and gender specific-prevalence rates that could be derived from the 16 studies. The prevalence of radiographic OA for the 50-year-old male and female participants was 5.8% and 7.3%, respectively, while the respective prevalence for 80-year-old male and female participants was 33.1% and 39.0%. We found an OR for having radiographic OA of 1.06 (95%CI [1.055-1.065], p < 0.001) per increasing year of age, and 1.30 (95%CI: 1.05-1.61], p = 0.014) for females. CONCLUSION: In the general population, radiographic thumb base OA is more prevalent in females and is strongly associated with age.

INTRODUCTION: Post-traumatic neuropathic pain is a major factor affecting the quality of life after finger trauma and is reported with considerable variance in the literature. This can partially be attributed to the different methods of determining neuropathic pain. The Douleur Neuropathique 4 (DN4) has been validated to be a reliable and non-invasive tool to assess the presence of neuropathic pain. This study investigated the prevalence of neuropathic pain after finger amputation or digital nerve repair using the DN4 questionnaire. METHODS: Patients with finger amputation or digital nerve repair were identified between 2011 and 2018 at our institution. After a minimal follow-up of 12 months, the short form DN4 (S-DN4) was used to assess neuropathic pain. RESULTS: A total of 120 patients were included: 50 patients with 91 digital amputations and 70 patients with 87 fingers with digital nerve repair. In the amputation group, 32% of the patients had pain, and 18% had neuropathic pain. In the digital nerve repair group, 38% of the patients had pain, and 14% had neuropathic pain. Secondly, of patient-, trauma-, and treatment-specific factors, only the time between trauma and surgery had a significant negative influence on the prevalence of neuropathic pain in patients with digital nerve repair. CONCLUSION: This study shows that persistent pain and neuropathic pain are common after finger trauma with nerve damage. One of the significant prognostic factors in developing neuropathic pain is treatment delay between trauma and time of digital nerve repair, which is of major clinical relevance for surgical planning of these injuries.

The aim of this study was to assess return to work (RTW) after open Triangular Fibrocartilage Complex (TFCC) reinsertion. RTW after open surgery for TFCC injury was assessed by questionnaires at 6 weeks, 3 months, 6 months, and 12 months post-operatively. Median RTW time was assessed on inverted Kaplan-Meier curves and hazard ratios were calculated with Cox regression models. 310 patients with a mean age of 38 years were included. By 1 year, 91% of the patients had returned to work, at a median 12 weeks (25%-75%: 6-20 weeks). Light physical labor (HR 3.74) was associated with RTW within the first 15 weeks; this association altered from 23 weeks onward: light (HR 0.59) or moderate physical labor (HR 0.25) was associated with lower RTW rates. Patients with poorer preoperative Patient-Rated Wrist Evaluation (PRWE) total score returned to work later (HR 0.91 per 10 points). Overall cost of loss of productivity per patient was 13,588. In the first year after open TFCC reinsertion, 91% of the patients returned to work, including 50% within 12 weeks. Factors associated with RTW were age, gender, work intensity, and PRWE score at baseline.
