Abstract
Background and Objective: Complex regional pain syndrome (CRPS) is a chronic condition characterized by severe regional pain, allodynia, hyperalgesia, and functional impairment. The aim of this systematic review is to investigate whether a familial subtype of CRPS (fCRPS) exists and to determine whether people with fCRPS have specific characteristics. Methods: Databases CINAHL, Medline, PsycINFO, and PubMed were searched with no date limitation. Quality of reporting was assessed using the Scottish Intercollegiate Guidelines Network scale and the Joanna Briggs Institute’s checklists. Results: Eight studies were included. Family relationships were defined as any immediate (i.e., parents or siblings) or blood relatives. A combination of participants with known or unknown causes for CRPS was recruited. The studies in this review support the potential for the existence of fCRPS, although this included less than 25% of those affected. People with potential fCRPS showed more severe symptoms, more sites involved, a higher percentage of spontaneous onset, and earlier age at onset. An elevated sibling recurrence risk ratio of 5.6 (95% confidence interval [CI], 3.0 to 9.8) was reported for people under 50. None of the studies established a pattern of heritability. Therefore, the most likely explanation for heritability would be a multifactorial model in which cumulative and interactive Gene × Environment effects may be involved. Conclusions: This systematic review supports the potential for the existence of fCRPS; however, all identified studies used uncontrolled case reports, case series, and case–control designs that cannot provide evidence of causation. Further studies are required to reveal the heritability and genetic structure of fCRPS.

Abstract
UNLABELLED Osteoporosis affects many aspects of daily life. The aim of this systematic review was to assess the effects of exercise interventions on functional outcomes in persons with osteoporosis, in comparison with controls. METHODS Four databases were searched and yielded 1587 citations. Two reviewers independently determined study eligibility, rated risk of bias, appraised methodological quality of studies, and resolved discordance by consensus. RESULTS A total of 28 studies examining 2113 participants met inclusion criteria; 25 studies were suitable for meta-analyses. Four categories of exercise were identified using the ProFaNE taxonomy. After removing studies with high risk of bias and sorting them into intervention sub-types, we were able to sufficiently reduce the heterogeneity. The standardized mean difference (SMD) favored multicomponent exercise for mobility (- 0.56, 95% CI [- 0.81, - 0.32], p = 0.06, I2 = 51%); balance (0.50, 95% CI [0.27, 0.74], p = 0.28, I2 = 21%); and self-reported measures of functioning (- 0.69, 95% CI [- 1.04, - 0.34], p = 0.02, I2 = 61%). Trials were judged at low or unclear risk of selection bias, indicating inadequate reporting and at high risk of performance bias due to lack of participant blinding. The mean methodological quality rating of the studies was 63.5% indicating moderate quality. CONCLUSIONS A multicomponent exercise program of high-speed training combined with simulated functional tasks is promising to enhance functional outcomes. Due to substantial clinical heterogeneity of the target groups and specific demands of exercise modes, it is unclear which exercise program is optimal.

Abstract
UNLABELLED The aim of this study was to categorize the facilitators and barriers of exercise and identify methods to promote exercise adherence in the osteoporosis population. Despite the fair methodological quality of included randomized controlled trials (RCTs), less than 75 % identified facilitators and barriers to exercise. Methods to promote and measure exercise adherence were poorly reported. INTRODUCTION Several studies have shown exercise to be successful in maintaining or increasing BMD in individuals with low bone mass. Yet, adherence to exercise is poor, with 50 % of those registered in an exercise program dropping out within the first 6 months, lack of time being the number one barrier in many populations. However, in the osteoporosis population, the main facilitator and barrier to exercise is still unclear. The aim of this study is to examine the extent to which RCTs reported the facilitators and the barriers to exercise and identified methods to promote adherence to an exercise program. METHODS PubMed, CINHAL, EMBASE, and the Cochrane Review were queried using a predefined search criterion, and the resulting citations were imported into DistillerSR. Screening was carried out by two independent reviewers, and articles were included in the analysis by consensus. The methodological quality of included studies was assessed using the PEDro scale. RESULTS Fifty-four RCTs examining exercise interventions in patients with osteopenia or osteoporosis were included. A spectrum of facilitators and barriers to exercise for osteoporotic patients were identified; however, no one facilitator was more frequently reported than the other. The most commonly reported barriers were lack of time and transportation. In most RCTs, methods to promote and measure exercise adherence were unsatisfactory. Of the 54 papers, 72 % reported an adherence rate to an exercise program; the lowest reported rate was 51.7 %, and the highest 100 %. CONCLUSIONS Most RCTs found were of fair quality; however, less than three quarters identified facilitators and barriers to exercise. Reporting of methods to promote and measure exercise adherence were low. Future work should be directed toward identifying major facilitators and barriers to exercise adherence within RCTs. Only then can methods be identified to leverage facilitators and overcome barriers, thus strengthening the evidence for efficacy of optimal interventional exercise programs. This review has been registered in PROSPERO under registration number CRD42016039941.

Abstract
OBJECTIVE To perform a systematic review on the efficacy of transcutaneous electrical nerve stimulation (TENS) for the treatment of rotator cuff tendinopathy in adults. METHODS A literature search was conducted in four databases (CINAHL, Embase, PubMed and PeDRO) for randomised controlled trials published from date of inception until April 2015, comparing the efficacy of TENS for the treatment of rotator cuff tendinopathy with placebo or any other intervention. Risk of bias was evaluated using the Cochrane risk of bias tool. Results were summarised qualitatively. RESULTS Six studies were included in this review. The mean methodological score was 49% (standard deviation 16%), indicating an overall high risk of bias. One placebo-controlled trial reported that a single TENS session provided immediate pain reduction for patients with rotator cuff tendinopathy, but did not follow the participants in the short, medium or long term. Two trials that compared ultrasound therapy with TENS reported discrepancy and contradictory results in terms of pain reduction and shoulder range of motion. Corticosteroid injections were found to be superior to TENS for pain reduction in the short term, but the differences were not clinically important. Other studies included in this review concluded that TENS was not superior to heat or pulsed radiofrequency. CONCLUSION Due to the limited number of studies and the overall high risk of bias of the studies included in this review, no conclusions can be drawn on the efficacy of TENS for the treatment of rotator cuff tendinopathy. More methodologically sound studies are needed to document the efficacy of TENS. Until then, clinicians should prefer other evidence-based rehabilitation interventions proven to be efficacious to treat patients with rotator cuff tendinopathy.

Abstract
Between 1995 and 2006, five intra-articular osteotomies of the head of the radius were performed in patients with symptomatic healed displaced articular fractures. Pre-operatively, all patients complained of persistent painful clicking on movement. Only patients with mild or no degenerative changes of the radial head and capitellum were considered for osteotomy. The operations were performed at a mean of 8.2 months (4 to 13) after injury and the patients were reviewed at a mean of 5.5 years (15 months to 12 years) after the osteotomy. The average Mayo Elbow Performance Index Score improved significantly from 74 before to 88 after operation, with four patients rated as good or excellent (p < 0.05). The subjective patient satisfaction score was 8.4 on a ten-point scale. All osteotomies healed and there were no complications. In this small series intra-articular osteotomy of the head of the radius was a safe and effective treatment for symptomatic intra-articular malunion without advanced degenerative changes.

Abstract
OBJECTIVE To establish the validity of three self-report scales used to measure function following arthroplasty for osteoarthritis (OA) of the carpometacarpal joint. METHOD Persons with OA of the carpometacarpal joint (n=122) were assessed on one occasion 9-117 months following tendon interposition arthroplasty. They completed three self-report measures of hand/upper limb disability: the Australian/Canadian Osteoarthritis Hand Index (AUSCAN), the Patient-Rated Wrist Hand Evaluation (PRWHE), and the Disabilities of Arm, Shoulder and Hand (DASH). They also completed the Short Form 36 (SF-36) and performed tests of strength, range of motion (ROM), and dexterity. Factor analysis and correlations were used to determine the association among the scales and subscales considered to measure similar constructs (e.g., pain and physical disability). Correlations between the scales and measures of impairment were also conducted to examine construct validity of the disability measures. t-Tests evaluated the hypotheses that subjects with isolated hand OA would have lower scores than those with additional joint involvement. RESULTS All three scales or their subscales loaded on one factor. Convergent validity of the disability measures was demonstrated by high correlations between similar subscales (r>0.75), and divergent validity by a lack of correlation between the measures and self-report hand appearance. As expected, correlations between disability and strength, dexterity, or a global measure of ROM were higher than with ROM of individual joints. The AUSCAN and the DASH were better able to discriminate those with localized hand OA from those with involvement of other joints. CONCLUSIONS The AUSCAN, PRWHE, and DASH are valid assessments of pain and/or disability of hand OA, and provide information distinct from impairment measures.

Abstract
PURPOSE This study investigated the relationship between severity of symptoms and success of nonoperative and operative treatment in patients with carpal tunnel syndrome (CTS). METHODS An observational cohort study regarding the management of CTS was conducted. Thirty patients referred to a tertiary hand centre with a diagnosis of CTS were prospectively followed. Twenty-five of the patients (47 affected hands) were available for long-term follow up to determine management outcomes. Self-report symptoms and physical impairments were assessed and documented at baseline, 6 weeks, and 12 weeks using the CTS Severity Score (SSS), the Disability-Shoulder, Arm and Hand Score (DASH), and the Levine Functional Score. Longer-term follow-up was conducted to identify status on outcome measures and whether patients proceeded to surgery. RESULTS Those who proceeded to surgery (n = 27/47 hands) had higher initial CTS SSS and DASH scores and also maintained higher scores compared to those who improved with conservative management (p < 0.05). Improvements occurred in the SSS (P < 0.0001), Functional Score (P < 0.001), and DASH score (P < 0.05) following surgery in the patients resistant to conservative management. Recovery of grip and dexterity was less satisfactory. DISCUSSION This study suggests that the SSS is useful in the triage of patients on surgical wait-lists as patients with high initial scores or failure to change in short-term follow-up are likely to proceed to surgical release. Despite prolonged symptoms and previous treatment, patients with lower SSS scores had moderate success with a second trial of conservative management.

Abstract
Our aim was to determine the clinical value of MRI and CT arthrography in predicting the presence of loose bodies in the elbow. A series of 26 patients with mechanical symptoms in the elbow had plain radiography, MRI and CT arthrography, followed by routine arthroscopy of the elbow. The location and number of loose bodies determined by MRI and CT arthrography were recorded. Pre-operative plain radiography, MRI and CT arthrography were compared with arthroscopy. Both MRI and CT arthrography had excellent sensitivity (92% to 100%) but low to moderate specificity (15% to 77%) in identifying posteriorly-based loose bodies. Neither MRI nor CT arthrography was consistently sensitive (46% to 91%) or specific (13% to 73%) in predicting the presence or absence of loose bodies anteriorly. The overall sensitivity for the detection of loose bodies in either compartment was 88% to 100% and the specificity 20% to 70%. Pre-operative radiography had a similar sensitivity and specificity of 84% and 71%, respectively. Our results suggest that neither CT arthrography nor MRI is reliable or accurate enough to be any more effective than plain radiography alone in patients presenting with mechanical symptoms in the elbow.

Abstract
OBJECTIVE To assess the reliability, validity and responsiveness of the Australian/Canadian (AUSCAN) Osteoarthritis Hand Index in both Likert (LK) and Visual Analogue (VA)-scaled formats. METHODS Two separate studies were conducted; the first addressing reliability and validity issues and the second addressing index responsiveness. In a group of 50 patients with osteoarthritis (OA) of the hand, test-retest reliability was assessed at a 1-week interval and internal consistency from single administrations of the Index. Construct validity was evaluated against several other outcome measures including the Functional Index for Hand Osteoarthritis (FIHOA), separate patient and physician global assessments, Doyle Index, grip strength, pinch grip, and Health Assessment Questionnaire. A 6-week washout retreatment design was used in a group of 44 OA hand patients to assess index responsiveness and comparative responsiveness against the FIHOA. RESULTS Reliability and construct validity coefficients confirm the reliability and construct validity of both the AUSCAN LK3.0 and AUSCAN VA3.0 Indices. The washout retreatment study establishes index responsiveness and suggests that the AUSCAN LK3.0 and AUSCAN VA3.0 Indices may be more responsive than the FIHOA. CONCLUSIONS The patient self-completed AUSCAN LK3.0 and AUSCAN VA3.0 Indices are reliable, valid and responsive and can be recommended as primary outcome measures for future hand OA clinical trials.

Abstract
OBJECTIVE To develop a reliable, valid, and responsive self-administered questionnaire to probe pain, stiffness and physical disability in patients with osteoarthritis (OA) of the hand. DESIGN In order to assess the dimensionality of the symptomatology of hand OA, a self-administered questionnaire was developed to probe various aspects of pain (10 items), stiffness (two items), and physical function (83 items). The question inventory was generated from eight existing health status measures and an interactive process involving four rheumatologists, two physiotherapists, and an orthopaedic surgeon. RESULTS Face-to-face interviews were conducted with 50 OA hand patients; 39 females and 11 males with mean age 62.8 years and mean disease duration 9.4 years. Items retained were those which fulfilled specified selection criteria: prevalence > or =60% and mean importance score approximating or exceeding 2.0 Item exclusion criteria included low prevalence, gender-based, ambiguous, duplicates or similarities, alternatives, composite items, and items that were too restrictive. This process resulted in five pain, one stiffness and nine function items which have been proposed for incorporation in the AUSCAN Index. CONCLUSIONS Using a traditional development strategy, we have constructed a self-administered multi-dimensional outcome measure for assessing hand OA. The next stage includes reliability, validity and responsiveness testing of the 15-item questionnaire.

Abstract
BACKGROUND AND PURPOSE The present study evaluated the concurrent validity of the NK hand dexterity test (NKHDT) by use of three separate analyses: (1) the correlation between the NKHDT and a criterion comparator (Jebson's Hand Function Test (JHFT)); (2) the correlation between both dexterity tests and a patient-rated function questionnaire; and (3) the ability of subscales to differentiate between subjects with and without upper extremity pathology. METHOD The study population included 40 individuals with a variety of musculoskeletal problems affecting the upper extremity and 10 individuals without any history of upper extremity problems. Both dexterity tests were administered on a single occasion according to a standard protocol. Subjects also completed a rating scale which evaluated self-care, household work, work and recreation on an 0-10-point scale. RESULTS The validity of the NKHDT was supported in all three analyses because: (1) the correlation between the NKHDT and JHFT subtests was moderate to strong (Pearson's r = 0.47-0.87) and stronger when the objects were more similar in size; (2) both scales correlated to a similar extent with patient-rated function (Pearson's r = 0.34-0.67); and (3) all subscales were statistically different between subjects with and without upper extremity pathology (p < 0.01). CONCLUSIONS The present study supports the use of the NKHDT as a measure of hand dexterity.

Abstract
The purposes of this study were to determine the overall incidence of distal radius fracture (DRF) complications, determine the incidence and types of DRF complications in a consecutive cohort of 250 patients with DRFs, describe DRF complications reported by patients compared with those reported by physicians, and formulate a DRF complication checklist to improve recording of DRF complications. We found that the overall complication rates vary widely (6% to 80%). Physician-reported complication data were collected for 236 patients, and a physician-reported complication rate of 27% was determined. A patient-reported complication rate of 21% was found for 207 patients whose patient-reported data were collected. We also noted that patients and physicians assess DRF complications differently: patients are more focused on symptoms than diagnoses. A DRF complication checklist was developed to improve prospective data collection. The checklist includes a classification for all DRF complications and allows for assessment of severity of each complication.

Abstract
BACKGROUND Treatment of unreconstructible comminuted fractures of the radial head remains controversial. There is limited information on the outcome of management of these injuries with arthroplasty with a metal radial head implant. METHODS The functional outcomes of arthroplasties with a metal radial head implant for the treatment of twenty-five displaced, unreconstructible fractures of the radial head in twenty-four consecutive patients (mean age, fifty-four years) were evaluated at a mean of thirty-nine months (minimum, two years). There were ten Mason type-III and fifteen Mason-Johnston type-IV injuries. Two of these injuries were isolated, and twenty-three were associated with other elbow fractures and/or ligamentous injuries. RESULTS At the time of follow-up, Short Form-36 (SF-36) summary scores suggested that overall health-related quality of life was within the normal range (physical component = 47 +/- 10, and mental component = 49 +/- 13). Other outcome scales indicated mild disability of the upper extremity (Disabilities of the Arm, Shoulder and Hand score = 17 +/- 19), wrist (Patient-Rated Wrist Evaluation score = 17 +/- 21 and Wrist Outcome Score = 60 +/- 10), and elbow (Mayo Elbow Performance Index = 80 +/- 16). According to the Mayo Elbow Performance Index, three results were graded as poor; five, as fair; and seventeen, as good or excellent. The poor and fair outcomes were associated with concomitant injury in two patients, a history of a psychiatric disorder in three, comorbidity in two, a Workers' Compensation claim in two, and litigation in one. Subjective patient satisfaction averaged 9.2 on a scale of 1 to 10. Elbow flexion of the injured extremity averaged 140 degrees +/- 9 degrees; extension, -8 degrees +/- 7 degrees; pronation, 78 degrees +/- 9 degrees; and supination, 68 degrees +/- 10 degrees. A significant loss of elbow flexion and extension and of forearm supination occurred in the affected extremity, which also had significantly less strength of isometric forearm pronation (17%) and supination (18%) as well as significantly less grip strength (p < 0.05). Asymptomatic bone lucencies surrounded the stem of the implant in seventeen of the twenty-five elbows. Valgus stability was restored, and proximal radial migration did not occur. Complications, all of which resolved, included one complex regional pain syndrome, one ulnar neuropathy, one posterior interosseous nerve palsy, one episode of elbow stiffness, and one wound infection. CONCLUSIONS Patients treated with a metal radial head implant for a severely comminuted radial head fracture will have mild-to-moderate impairment of the physical capability of the elbow and wrist. At the time of short-term follow-up, arthroplasty with a metal radial head implant was found to have been a safe and effective treatment option for patients with an unreconstructible radial head fracture; however, long-term follow-up is still needed.

Abstract
The number of interventions and the related costs of management of scar are increasing. Despite increasing emphasis on evidence-based practice, there is little comparative data on which to base treatment selection. The ability of a therapist to evaluate the natural progression of a scar or treatment efficacy may be hampered by the nature of the particular scar, the lack of conformity in descriptions of scar, and the lack of reliable standardized outcome measurements. This literature review seeks to clarify the constructs measured for scar and present the measures currently available for use.

Abstract
Measurement of outcome after treatment of elbow pathology has tended to rely on nonstandardized scales and isolated impairment measures, particularly range of motion. This study evaluated the reliability and validity of patient questionnaires with patients with elbow pathology. Patients with a variety of complaints affecting the elbow (n = 70) completed four questionnaires-the American Shoulder and Elbow Surgeons Elbow Form; the Patient-rated Elbow Evaluation; the Disabilities of Arm, Shoulder and Hand questionnaire; and Short Form 36--during clinic attendance and returned repeat questionnaires by mail (n = 50). The test-retest reliability was determined to be acceptable for all four instruments (16 of 19 ICCs for subscales > 0.78; all ICCs for total score s > 0.90). Four constructs on the relationship expected between outcome measures, determined prior to data collection, were observed as anticipated, supporting the validity of outcome questionnaires. This study supports the use of these instruments to evaluate outcome in patients with elbow pathology.

Abstract
Computed tomography was used to image the distal radioulnar joint (DRUJ) for instability. Four methods were used to quantify subluxation of the DRUJ: the Mino criteria, the epicenter method, the congruency method, and a new method called the radioulnar ratio (RUR). Validity of the various methods was evaluated in clinical and laboratory situations. Rheumatoid patients with symptomatic DRUJ pathology had significantly more abnormal RUR values (100% vs 73% [epicenter method] and 88% [Mino criteria]). The RUR detected instability sooner in a progressive laboratory-induced instability model. The intraobserver and interobserver reliability of the RUR was high, with intraclass correlation coefficients of 0.89 and 0.87, respectively. The RUR demonstrated superior performance in the diagnosis of DRUJ subluxation.

Abstract
The consistency of pinch scores obtained with new devices compared with that of scores obtained by traditional devices underlies the ability of therapists to use new devices when communicating about patient status or using normative data published for these traditional devices. This study determined the inter-instrument reliability of pinch strength scores obtained using three commercially available pinch gauges (B&L, JTech and NK pinch gauges). Volunteers (average age, 32 years; range, 18 to 80 years; 19 women, 21 men; 20 with hand pathology, 20 without hand pathology) were tested on a single occasion using all three devices. Each subject was tested with the elbow at 90%, the forearm neutral, and the wrist in neutral deviation. Three trials of maximum tripod and key pinch strength were performed. The hand tested first and the instrument order were randomized. Intraclass correlation coefficients (ICCs) and their 95% confidence intervals were calculated. The inter-instrument error and its associated boundaries (+/- 2 SD) were also calculated. Intraclass correlation coefficients were high for both affected and unaffected hands in patients (> 0.90) and in subjects without pathology (> 0.80). Average instrument error was close to zero and was similar between instruments, indicating a lack of instrument bias. These results suggest that pinch strength scores obtained with any of these three pinch gauges can be compared with normative data obtained with either of the other pinch gauges.

Abstract
Twenty-two consecutive patients (23 wrists) underwent open reduction internal fixation of dorsal perilunate dislocations and fracture-dislocations through combined dorsal and volar approaches. One of 5 experienced wrist surgeons performed these procedures within an average of 3 days of injury (range, 0-26 days) and intercarpal fixation was kept within the proximal carpal row. Motion was instituted an average of 10 weeks (range, 5-16 weeks) after injury. All patients were males. The average age at the time of injury was 32 years (range, 16-60 years). The average follow-up period was 37 months (range, 13-65 months). Average flexion-extension motion arc and grip strength in the injured wrist were 57% and 73%, respectively, compared with the contralateral wrist. The scapholunate angle increased and the revised carpal height ratio decreased over time, which was statistically significant for both measurements. Three patients (3 wrists) required wrist arthrodesis and a fourth patient had an immediate scaphoid excision and 4-corner arthrodesis secondary to an irreparable scaphoid fracture. One patient required a proximal row carpectomy to treat septic arthritis. Nine of the remaining 18 wrists had radiographic evidence of arthritis, most often at the capitolunate or scaphocapitate articulations. Short form-36 mental summary scores were significantly greater than age- and gender-matched US population values; physical summary scores were significantly less. The disabilities of arm, shoulder, and hand evaluation, Mayo wrist score, and patient-rated wrist evaluation all reflected loss of function. Seventy-three percent of all patients had returned to full duties in their usual occupations and a total of 82% were employed.

Abstract
BACKGROUND The objective of the present study was to review the results of primary total elbow arthroplasty with use of the Coonrad-Morrey prosthesis. Two hypotheses were tested: (1) the results in patients with inflammatory arthritis would be superior to those in patients with a traumatic or posttraumatic condition, and (2) the isometric extensor torque after total elbow arthroplasty would be significantly less than that of the contralateral elbow. METHODS Forty-seven consecutive patients (fifty-one elbows) had the operation performed by one of three surgeons between November 1, 1989, and June 30, 1996. Thirty-six surviving patients (thirty-nine elbows) were available for follow-up. The mean duration (and standard deviation) of follow-up was 50 +/- 11 months (range, twenty-four to ninety-seven months). The mean age at the time of the operation was 64 +/- 11 years (range, twenty-seven to eighty-seven years). Eighteen patients (twenty-one elbows) had inflammatory arthritis. Eighteen patients (eighteen elbows) had an acute fracture or posttraumatic condition (posttraumatic osteoarthritis in eight, an acute fracture of the humerus in seven, nonunion of the distal aspect of the humerus in two, and primary osteoarthritis in one). The patients were evaluated with use of questionnaires (the Mayo elbow performance index, the Short Form-36 [SF-36], and the Disabilities of the Arm, Shoulder and Hand [DASH] Questionnaire); clinical examination by an orthopaedic surgeon who was not involved with the pre-operative, operative, postoperative, or follow-up care; radiographs; and elbow strength-testing with an isokinetic dynamometer. RESULTS The mean score (and standard deviation) on the Mayo elbow performance index for the group that had inflammatory arthritis (90 +/- 11 points) was significantly higher than that for the group with a traumatic or posttraumatic condition (78 +/- 18 points) at the time of the latest follow-up (p < 0.05). In both groups, the mean extensor torque of the involved elbow was significantly less than that of the contralateral elbow (p < 0.05). No significant difference between the groups was found with respect to the flexion-extension arc of motion. Ten elbows (26 percent) had ulnar nerve dysfunction (a transient deficit in six and a permanent deficit in four); nine (23 percent), an intraoperative fracture (of the humeral diaphysis in four, of the ulnar diaphysis in four, and of the olecranon in one); three (8 percent), a periprosthetic infection; three, a triceps disruption; and one (3 percent), a revision because of a fracture of the ulnar component. There were no other revisions. Of the thirty-four elbows with complete radiographic follow-up, twenty-three had no change in the bone-cement interface. Progressive radiolucency was noted around the ulnar prosthesis in eight elbows, around the humeral prosthesis in one elbow, and around both components in two elbows. CONCLUSIONS Patients who had a total elbow arthroplasty with use of a semiconstrained Coonrad-Morrey prosthesis were generally satisfied; the mean level of patient satisfaction was 9.2 of a possible 10 points for those who had inflammatory arthritis and 8.6 points for those who had a fracture or posttraumatic condition. The rates of complications involving the ulnar nerve, intraoperative fracture, triceps disruption, deep infection, and periprosthetic radiolucency are of concern.

Abstract
We evaluated the responsiveness of patient questionnaires and physical testing in the assessment of recovery after distal radius fracture. Patients (n = 59) were assessed at their baseline clinic visit and again 3 and 6 months after injury. At each visit patients completed a short form-36, Disability of the Arm, Shoulder, and Hand questionnaire, and patient-rated wrist evaluation (PRWE). At 3 and 6 months grip strength, range of motion, and dexterity were analyzed. Standardized response means (SRM) and effects sizes were calculated to indicate responsiveness. The PRWE was the most responsive. Both the PRWE (SRM = 2.27) and the Disability of the Arm, Shoulder, and Hand (SRM = 2.01) questionnaire were more responsive than the short form-36 (SRM = 0.92). The physical component summary score of the short form-36 was similar to that of the physical component subscales. Questionnaires were highly responsive during the 0- to 3-month time period when physical testing could not be performed. Of the physical tests, grip strength was most responsive, followed by range of motion. Responsive patient-rating scales and physical performance evaluations can assist with outcome evaluation of patients with distal radius fracture.

Abstract
Measurement of lateral rotation range of motion (ROM) is frequently performed during shoulder evaluation. The purpose of this study was to determine the intratester and intertester reliability of goniometric measurement of passive lateral rotation ROM of the shoulder. Two experienced PTs performed the testing in a randomized block design. They were blinded to all clinical information and to their goniometric readings. Passive lateral rotation ROM of the shoulder was assessed in 34 patients with a variety of shoulder pathologies. Patients were placed in the supine position with the arm abducted approximately 20 degrees to 30 degrees. A standard goniometer, placed along the joint axis by the therapist, was red by an independent assistant. Intraclass correlation coefficients (ICCs) and their associated 95% confidence intervals were calculated. Intratherapist ICCs (0.88 and 0.93) and intertherapist ICCs (0.85 and 0.80) were high. These findings suggest that reliable measures of passive lateral rotation ROM of the shoulder can be obtained from patients with shoulder pathology using standard goniometry and by placing the patient in a supine position.

Abstract
The NK computerized hand evaluation system includes a dexterity board that can be used to measure patients' ability to manipulate small, medium, and large objects. This study evaluated the test-retest reliability of the NK dexterity test. Thirty-seven healthy subjects aged 20 to 54 years completed two occasions of dexterity testing. Each occasion included bilateral dexterity tests consisting of two trials of each of three subtests. Intraoccasion intraclass correlation coefficients (ICCs) indicated fair to excellent reliability (ICC, 0.53-0.86). Interoccasion ICCs tended to be lower and ranged from 0.39 to 0.83, depending on the subtest. Reliability tended to be higher with the dominant hand than with the nondominant hand. Improvements in equipment design and alternative testing protocols may be needed to ensure consistently excellent reliability in dexterity scores with this test.

Abstract
PURPOSE To determine the reliability of a questionnaire designed to assess forearm pain and function in patients with lateral epicondylitis. METHODS Forty-seven patients with unilateral lateral epicondylitis completed a patient-related forearm evaluation questionnaire (PRFEQ) on two occasions. Intraclass correlation coefficients (ICC 2,1), standard error of measurement (SEM), and 95% confidence intervals (CIs) were determined for the whole group and for three subgroup comparisons of male vs. female subjects, subacute vs. chronic lateral epicondylitis, and work-related vs. non-work-related lateral epicondylitis. RESULTS The test-retest reliability for the overall PRFEQ (ICC, 0.89), and its pain (ICC, 0.89) and function (ICC, 0.83) subscales was excellent. Test-retest reliability for patients with work-related lateral epicondylitis (ICC, 0.80) was significantly (p = 0.018) less than for patients with non-work-related lateral epicondylitis (ICC, 0.94). CONCLUSIONS The PRFEQ can provide a simple, quick, and reliable estimate of arm pain and function in patients with lateral epicondylitis. However, large SEM and 95% CIs limit its ability to accurately predict individual scores.

Abstract
OBJECTIVE The goal of this study was to develop a reliable and valid tool for quantifying patient-rated wrist pain and disability. DESIGN Survey, tool development, reliability, and validity study. SETTING Upper extremity unit. PARTICIPANTS One hundred members of the International Wrist Investigators were surveyed by mail to assist in development of the scale. Patients with distal radius (n = 64) or scaphoid (n = 35) fractures were enrolled in a reliability study, and 101 patients with distal radius fractures were enrolled in a validity study. INTERVENTION Information from the expert survey, biomechanical literature, and patient interviews was used as a basis for item generation and definition of structural limitations for a scale that would be practical in the clinic. Patients with distal radius or scaphoid fractures completed the Patient-Rated Wrist Evaluation (PRWE) on two occasions to determine test-retest reliability. Patients with distal radius fractures (n = 101) completed the PRWE and the SF-36 and were tested with traditional impairment measures at baseline and at two, three, and six months after fracture to determine construct and criterion validity. MAIN OUTCOME MEASURES Reliability coefficients (ICCs) and validity correlations (Pearson product moment correlations). RESULTS Patient opinions on pain and on ability to do activities of daily living and work were thought to be the most important dimensions to include in subjective outcome tools. Brevity and simplicity were seen as essential in the clinic environment. A fifteen-item questionnaire (the PRWE) was designed to measure wrist pain and disability. Test-retest reliability was excellent (ICCs > 0.90). Validity assessment demonstrated that the instrument detected significant differences over time (p < 0.01) and was appropriately correlated with alternate forms of assessing parameters of pain and disability. CONCLUSIONS The PRWE provides a brief, reliable, and valid measure of patient-rated pain and disability.

Abstract
The purpose of this study was to examine intratester, intertester, and interdevice reliability of range of motion measurements of the elbow and forearm. Elbow flexion and extension and forearm pronation and supination were measured on 38 subjects with elbow, forearm, or wrist disease by 5 testers. Standardized test methods and a randomized order of testing were used to test groups of patients with universal standard goniometers, a computerized goniometer, and a mechanical rotation measuring device. Intratester reliability was high for all 3 measuring devices. Meaningful changes in intratester range of motion measurements taken with a universal goniometer occur with 95% confidence if they are greater than 6 degrees for flexion, 7 degrees for extension, 8 degrees for pronation, and 8 degrees for supination. Intertester reliability was high for flexion and extension measurements with the computerized goniometer and moderate for flexion and extension measurements with the universal goniometer. Meaningful change in interobserver range of motion measurements was expected if the change was greater than 4 degrees for flexion and 6 degrees for extension with the computerized goniometer compared with 10 degrees and 10 degrees, respectively, if the universal goniometer was used. Intertester reliability was high for pronation and supination with all 3 devices. Meaningful change in forearm rotation is characterized by a minimum of 10 degrees for pronation and 11 degrees for supination with the universal goniometer. Reliable measurements of elbow and forearm arm movement are obtainable regardless of the level of experience when standardized methods are used. Measurement error was least for repeated measurements taken by the same tester with the same instrument and most when different instruments were used.

Abstract
The primary purpose of the study was to examine the role of the posterior cruciate ligament (PCL) in knee-joint proprioception after total knee arthroplasty (TKA). Knee-joint proprioception was measured in 10 patients with nonsacrificed PCL TKAs and 10 with sacrificed PCL TKAs. Knee-joint proprioception was evaluated through reproduction of static knee angles using a Penny and Giles electrogoniometer. The primary variable was absolute angular error (AAE). AAE was defined as the absolute value of the difference between the test angle and the patient's perceived version of the test angle. Proprioception deficit was compared to the WOMAC questionnaire which evaluates pain, stiffness, and physical function of the lower extremity. No significant difference was found between the nonsacrificed PCL TKA (4.33 degrees +/- 1.52 degrees) and sacrificed PCL TKA (4.38 degrees +/- 1.39 degrees) AAE values (P > .4). Furthermore, no significant differences were observed in the WOMAC questionnaire scores for all three parameters between the two types of knee prosthesis (P > .35). The current findings suggest that the preservation of the PCL in TKA may not improve knee-joint proprioception and subsequently may not improve TKA functional performance.

Abstract
BACKGROUND AND PURPOSE Findings related to joint function can be recorded with movement diagrams or by characterizing the "end-feel" according to the procedure described by Cyriax. Because both methods are used to classify pain and resistance in relation to joint range of motion (ROM), the purpose of this study was to simultaneously evaluate the reliability of these categorizations in a patient sample. SUBJECTS Two physical therapists performed 2 assessments of passive lateral rotation of the shoulder in 34 patients. METHODS Pain and resistance findings were recorded using movement diagrams and end-feel categories. Intraclass correlation coefficients (ICC[2,1]) were used to analyze the ratio (movement diagram) data, and kappa statistics (kappa) were used to analyze the categorical (end-feel) data. RESULTS Intrarater ICCs varied from .58 to .89. Interrater ICCs for locating maximum pain and resistance in joint ROM varied from .85 to .91. Other interrater ICCs were lower (ICC = .34-.88). Intrarater kappa values for end-feel were moderate (kappa = .48-.59), and interrater kappa values were substantial (kappa = .62-.76). CONCLUSION AND DISCUSSION Movement diagram measures conceptually related to the end of joint ROM and end-feel were highly reliable. This finding and the fact that additional end-feel categories were introduced in the study may partially explain the end-feel reliability findings. Consideration of their use in future studies may help to determine their clinical utility.

Abstract
The intra- and interobserver variability of 3 techniques for measuring the humpback deformity of 37 scaphoids using longitudinal computed tomography was assessed. The 3 measuring techniques were the lateral intrascaphoid angle, the dorsal cortical angle, and the height-to-length ratio. The intraobserver reliability of the intrascaphoid angle was poor; the dorsal cortical angle was moderate to excellent, and the height-to-length ratio was excellent. The interobserver reliability of the intrascaphoid angle was poor to moderate, the dorsal cortical angle was moderate to excellent, and the height-to-length ratio was moderate to excellent. For all 3 observers, the intra- and interobserver reliability was the best for the height-to-length ratio and worst for the intrascaphoid angle. The height-to-length ratio is the most reproducible method of assessing the humpback deformity. Clinical correlation is required to establish whether the height-to-length ratio will be of value in predicting the outcome of fractures of the scaphoid.

Abstract
Since 1986 the senior author has performed a matched hemiresection with retinacular/capsular interposition for patients with painful disorders of the distal radioulnar joint. A retrospective review of 55 wrists was performed by an independent hand surgeon and hand therapist. Forty-nine of 54 wrists in the surviving patients were clinically and radiographically reviewed with an average follow-up interval of 36 months. Subjective assessment included a visual analog rating of pain improvement and satisfaction with treatment. Objective assessment included examination of range of motion, strength, stability, and standardized functional testing with the Jebsen and Minnesota Rate of Manipulation tests. Thirty-five patients reported pain improvement and 41 patients were satisfied. The range of supination and pronation increased from 54 degrees and 67 degrees, respectively, to 72 degrees and 72 degrees. Functional ability as measured by the Jebsen test was similar to the contralateral wrist. Patients had most difficulty turning large objects. The clinical, objective, functional, and x-ray films results correlated poorly with pain improvement and patient satisfaction. Complications included one infection, one reflex sympathetic dystrophy, one neuroma of the dorsal sensory branch of the ulnar nerve, and four cases of ulnar-carpal impaction. Pain relief was the primary determinant of patient satisfaction and should be considered the indication for surgery.

Abstract
Both hands of 39 patients who had symptoms of pain and/or numbness in one or both hands were tested by two hand therapists using the full kit of Semmes-Weinstein monofilaments (SWMFs). The SWMF thresholds were obtained for the thumb, the index finger, and the long and small fingers. These thresholds were classified as normal or abnormal based on four decision rules and two criterion measures. Decision rules were based on whether SWMF 2.83 or 3.22 would be the best limit of normality, and whether the small finger should be used for within-subject comparisons. The criterion measures were the highest threshold of all three radial digits and the highest threshold of the long finger alone. Intertherapist agreement on normality was fair to moderate (kappa = 0.22-0.51), varying according to decision rules and criterion measures. Reliability was higher when the additional comparison with the small finger was omitted. High accuracy in identifying cases of carpal tunnel syndrome (CTS) was possible, but accuracy varied moderately between testers and greatly according to decision rules and criterion measurements. The best overall accuracy (81%-82% sensitivity and 57%-86% specificity) was achieved when SWMF 2.83 was used as the upper limit of normality and the small finger was used for within-subject comparison, and when data from the long finger alone were used for decision making.

Abstract
The purposes of this study were to examine the interrater reliabilities of grip, lateral pinch, and tripod pinch measurements in patients with cumulative trauma disorders. Thirty-eight patients with unilateral (n = 28) or bilateral (n = 10) cumulative trauma disorders were tested independently by two hand therapists, during a one-hour period. The tests were completed in a normal hand clinic environment using the standard protocol recommended by the American Society of Hand Therapists. Interrater reliability coefficients for the scores obtained using either a single repetition or the mean of three repetitions were very high (intraclass correlation coefficient [ICC] > 0.87) for all strength measurements. As a result, strength determination in this patient group, when performed by different hand therapists, may be considered reliable.
