ABSTRACT
BACKGROUND: Chronic pain affects 70% of individuals with spinal cord injury (SCI) and leads to declines in health and quality of life. Neuropathic and nociceptive pain are phenotypes derived from different mechanisms that contribute to pain perception. The objective of this research was to investigate differential pain responses to moderate-to-vigorous physical activity (MVPA) in two chronic pain phenotypes: neuropathic and nociceptive pain. METHODS: Community-based physical activity levels were collected for one week in 17 individuals with SCI using a wrist-worn accelerometer, and daily pain ratings were assessed and categorized by phenotype. Physical activity levels were summarized to calculate minutes of MVPA. Correlational analyses were conducted to compare relationships between pain intensity and MVPA across individual participants and between pain phenotype groups. RESULTS: The neuropathic pain group revealed significant negative correlation between MVPA and pain intensity. In the nociceptive pain group, there was no significant correlation between MVPA and pain intensity. Further analysis revealed two subgroups of positive (N = 4) and negative (N = 3) correlations between MVPA and pain intensity. Pain location differed between the subgroups of nociceptive pain. Individuals with negative correlation experienced neck and upper back pain, whereas individuals with positive correlation experienced unilateral upper extremity pain. CONCLUSION: Differential relationships exist between pain phenotypes and MVPA in individuals with SCI. Pain location differed between the subgroups of nociceptive pain, which we presume may indicate the presence of nociplastic pain in some individuals. These results may contribute to the advancement of personalized pain management by targeting non-pharmacological interventions for specific pain phenotypes.Trial registration: ClinicalTrials.gov identifier: NCT05236933..
ABSTRACT
OBJECTIVE: To assess the effects of group tele-exercise participation on physical activity (PA) determinants and behavior as identified by social cognitive theory (SCT) in individuals with spinal cord injury (SCI). DESIGN: This clinically registered non-randomized trial [NCT05360719] used a single-group parallel mixed methods design. Quantitative and qualitative primary measures were assessed at pre-program and after 8-week intervention completion (post-program), with an additional 8-week period retention to capture quantitative assessments only. SETTING: Community. PARTICIPANTS: Individuals with chronic SCI (N=22, injury duration 2-50 years) aged 26-68 years (10 male/12 female). INTERVENTION: An 8-week group tele-exercise program for individuals with SCI consisting of biweekly 60-minute classes delivered via live Web-conferencing software. MAIN OUTCOME MEASURES: Exercise self-efficacy (Exercise Self-efficacy Scale for SCI: ESES), outcome expectations for exercise (Multidimensional Outcome Expectations for Exercise: MOEES), weekly PA minutes measured through quantitative assessments (Leisure Time PA Questionnaire for SCI: LTPAQ), and parallel qualitative thematic analysis of focus group interview transcripts. RESULTS: Congruence between numeric and thematic findings was present for exercise self-efficacy and self-evaluative exercise outcome expectations. Improved exercise self-efficacy was influenced by exercise knowledge gained during program participation. Increased expectations of internal exercise outcomes, such as influence on psychological state and overall mood, occurred after program participation. Participant descriptions of the portability and sustainability of the program leading to added movement in everyday life were not reflected in the numeric scores of LTPAQ assessment. CONCLUSIONS: Participation in an 8-week group tele-exercise program positively affected personal determinants of PA behavior immediately after participation. Future investigations should include a control group and biophysical PA measures such as wearable digital health devices.

Background: Individuals with SCI are 1.5 times more likely to be sedentary compared to adults without disabilities or chronic health conditions. It is therefore imperative to develop and evaluate innovative facilitation strategies for physical activity behavior in this population. Objectives: As an insightful step to creating and evaluating tailored physical activity interventions for individuals with SCI, we evaluated demographic, psychosocial, and physical characteristics of those who choose to engage in physical activity by enrolling in a group exercise study. Design/Methods: We conducted a cross-sectional analysis detailing demographic features and baseline outcomes of those with SCI enrolled in a group tele-exercise study who were classified as regular exercisers versus nonregular exercisers per the American College of Sports Medicine exercise guidelines. Between-group differences for psychosocial and physical outcomes were assessed with chi-square and Mann-Whitney U tests (p < .05). Results: Twenty-seven adult volunteers enrolled in the study (exercisers = 14, nonexercisers = 13). Groups were comparable for biological sex, gender identity, self-reported racial group(s), and current age. Exercisers demonstrated significantly shorter duration of injury compared to nonexercisers (p = .012). Exercisers exhibited significantly higher exercise self-efficacy (p = .017) and increased reported weekly minutes in vigorous intensity leisure time physical activity (p = .029). Conclusion: Nonexercisers with SCI demonstrate increased injury duration and reduced exercise self-efficacy compared to active peers. These factors should be addressed in the design and delivery of SCI-specific physical activity interventions to increase the likelihood of this critical health behavior over time.

BACKGROUND AND PURPOSE: More than 50% of individuals with spinal cord injury (SCI) report no regular exercise due to numerous barriers to participation. Tele-exercise services offer viable solutions to reduce barriers. However, limited evidence for SCI-specific tele-exercise programs is available. The purpose of this study was to evaluate the feasibility of a synchronous group tele-exercise program designed for individuals with SCI. METHODS: Explanatory sequential mixed-methods design assessed feasibility of a synchronous 2-month biweekly group tele-exercise program for individuals with SCI. Numeric measures of feasibility were first collected (recruitment rate, sample features, retention, attendance), followed by postprogram interviews with participants. Thematic analysis of experiential feedback elaborated on numeric findings. RESULTS: Eleven volunteers (ages = 49.5 ± 16.7 years) with SCI (range: 2.7-33.0 years) enrolled within 2 weeks of recruitment initiation. Retention was 100% retention at program completion. Median number of live classes attended per participant was 10 (62.5%). Participants described that attendance and satisfaction were facilitated by program-specific features including coinstruction by instructors with SCI-specific knowledge and lived experience, as well as group structure. Participants reported increased exercise knowledge, confidence, and motivation. DISCUSSION AND CONCLUSIONS: This study demonstrated feasibility of a synchronous group tele-exercise class for individuals with SCI. Key features facilitating participation include class length, frequency, coleadership by individuals familiar with SCI and exercise instruction, and group motivation. These findings begin to examine a viable tele-service strategy that could be employed as a bridge among rehabilitation specialists, community fitness instructors, and clients with SCI to increase physical activity access and behavior.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1 available at: http://links.lww.com/JNPT/A442 ).

OBJECTIVE: Over the past half century, the landscape of life and aging with spinal cord injury (SCI) has changed drastically, in part due to medical advancements and the rapidly increasing aging population. With these changes comes a critical need for rehabilitation professionals to understand aging with SCI in relation to strategies that support health maintenance over time. The purpose of this study was to identify and describe the meaning of health maintenance and aging outlook from the perspectives of individuals living with SCI. METHODS: A qualitative descriptive approach using focus group interviews and thematic analysis was used to generate a rich understanding of shared experiences with SCI by allowing for discussion among participants. RESULTS: Participants were 24 individuals ranging in age from 22 to 76 years who were living with chronic SCI (>12 months), with injury duration ranging from 3 to 47 years. Health maintenance was connected to 3 themes: self-management routine to prevent secondary health conditions; importance of injury acceptance over time; and engagement with disability networks. Aging outlook was linked to fear of functional dependence and lack of evidence-based education on aging with SCI. CONCLUSION: These findings suggest that individuals living with SCI would benefit from clinical support that acknowledges psychological and social aspects of health beyond physical routines. IMPACT: These findings inform the development and implementation of SCI-related interventions to maximize healthy aging. It is crucial for clinicians and researchers to investigate issues beyond routine self-management and functional independence to support the emotional adjustment of life with SCI. Unique personal considerations based on life stage when injured warrant investigation. Education and advocacy for peer support is imperative at all life stages given its positive impact on health.

CONTEXT: The purpose of this study was to determine test-retest reliability of upper-extremity muscle activity and kinematics during submaximal adapted rowing. DESIGN: A repeated-measures design was used. METHODS: Data were collected on 10 individuals (7 male and 3 female) with mobility impairment. Surface electromyography of muscles of the dominant arm (upper, middle, and lower trapezius, anterior and posterior deltoid, latissimus dorsi, and infraspinatus) was acquired. Muscle activity was analyzed using the area under the curve, peak amplitude, and mean amplitude. Kinematic analysis determined joint motions for shoulder plane and angle of elevation, and trunk flexion/extension, and rotation at the catch (0%) and finish (100%) of the stroke. Three submaximal rowing trials (20 strokes each) were completed with the middle 10 strokes of each trial averaged for analysis. RESULTS: An interclass correlation coefficient (3, 10) determined test-retest reliability across trials (interclass correlation coefficient defined as poor < .5; moderate .5-.75; and good .75-.9). Moderate to excellent reliability existed across all muscles for the area under the curve, peak amplitude, and mean amplitude. Excellent reliability was seen for all kinematic measures. CONCLUSION: Results indicate upper-extremity muscle activity and kinematics of the adapted rowing stroke are reliable in a diverse group of individuals with mobility impairment.

Lifestyle physical activity following spinal cord injury (SCI) is critical for functional independence, mental wellness, and social participation, yet nearly 50% of individuals with SCI report no regular exercise. The objective of this study was to better understand factors leading to this participation gap by capturing the physical activity perspectives of individuals living with SCI. We completed small group interviews with nine individuals living with SCI across the United States. Iterative thematic analysis systematically revealed meaningful core concepts related to physical activity engagement with SCI. Emergent themes revealed challenges to lifestyle physical activity behavior including gaps in physical activity education, isolation during psychological adjustment, and knowledge limitations in community exercise settings. A secondary theme related to the COVID-19 pandemic emerged, highlighting additional environmental constraints affecting participation. Our findings suggest that most physical activity education is delivered during inpatient rehabilitation and is related to physical function. Lifetime physical activity strategies are achieved through self-education and peer networking. Personal motivators for physical activity include secondary condition prevention, while social and emotional barriers prevent regular adherence. These findings can inform the development and delivery of physical activity programs to maximize physical activity engagement in individuals living with chronic SCI.

ABSTRACT: Exercise-induced hypoalgesia related to physical activity produces sensory adaptations, but its mechanism remains unclear. Quantitative sensory testing is an effective measurement tool to identify sensory changes, but the extent of evidence linking quantitative sensory testing and physical activity has not been explored. The purpose of this scoping review is to synthesize the evidence on using quantitative sensory testing to evaluate psychophysical changes related to physical activity in adult populations. The researchers developed a comprehensive search strategy with a Health Sciences Librarian using the Arksey and O'Malley Methodological framework. Four databases (Medline [PubMed], CINAHL, Web of Science, and Embase) were searched for peer-reviewed primary research. After 2790 articles were evaluated, 196 studies were included for final review. More than half of studies used randomized controlled trial design (50.5%), followed by quasi-experimental (24.0%) and observational (25.5%) strategies. Healthy adults (42.9%) and individuals with chronic health conditions (20.9%) were examined most frequently. Aerobic (27.6%) and strength (21.4%) physical activity types were most commonly studied. Static quantitative sensory testing measures of pressure pain threshold (84%) were used most frequently. The findings of this scoping review demonstrate available evidence for quantitative sensory testing as a measurement tool of neuromodulation related to physical activity in adult populations. A systematic review is warranted to examine outcomes and recommendations.

STUDY DESIGN: Retrospective study. OBJECTIVES: We aimed to characterize the convergent disruptions of the structural connectivity based on network modeling technique (i.e., graph theory) to identify significant changes in network organization/reorganization between uninjured and chronic spinal cord injury (SCI) participants. SETTING: USA. METHODS: Ten adult participants including 4 with chronic SCI and 6 uninjured were scanned using a multi-shell diffusion imaging on a 3.0 T MR scanner. Whole brain structural connectivity matrix was estimated by performing the quantification of the number of white matter fibers (called edges) connecting each possible pair of brain region (called nodes). Brain regions were defined according to Desikan-Killiany cortical atlas. Using connectivity matrix, connectivity strength as well as six different graph theoretical measurements were computed for each participant. They include: (1) global efficiency; (2) local efficiency; (3) degree; (4) betweenness centrality; (5) average shortest length and (6) clustering coefficient. Finally network based statistics was applied to extract nodes/connections with significant differences between groups (uninjured vs SCI). RESULTS: The SCI group showed significant decreases in betweenness centrality in the left precentral gyrus (T-score=2.98, p value=0.02), and the right caudal middle frontal gyrus (score = 2.35, p value=0.047). It also showed significant decrease in left transverse temporal gyrus (T-score=2.36, p value=0.046) in clustering coefficient. In addition, altered regions in the occipital and parietal lobe were also identified. CONCLUSION: These results suggest that not only local but also global alterations of the white matter occur after SCI. The proposed modeling technique has the potential to serve as a screening tool to identify any areas of the brain affected after SCI.

STUDY DESIGN: Cross-sectional analysis of baseline data of a longitudinal cohort study. OBJECTIVES: Little evidence exists on pain-related psychosocial factors in individuals with newly acquired spinal cord injury (SCI). To understand a biopsychosocial model of pain, we must first understand the presenting psychological pain-related factors at injury onset. Therefore, we assessed musculoskeletal pain and pain-related psychological constructs in a group of individuals with newly acquired SCI. We hypothesized that individuals with new SCI would report musculoskeletal shoulder pain with elevated levels of kinesiophobia and pain catastrophizing. SETTING: Data were collected in three rehabilitation hospitals located in urban and suburban communities. METHODS: Thirty-five individuals with newly acquired SCI participated. Demographics, Musculoskeletal Pain Survey shoulder subscale, Tampa Kinesiophobia Scale-11, Pain Catastrophizing Scale, Fear of Pain Questionnaire, Chronic Pain Coping Inventory-42, and Subjective Quality of Life Questionnaire were administered. Descriptive analysis of all measures was determined and relationships between pain and psychosocial measures determined. RESULTS: Moderate shoulder pain existed in 40% of people with new SCI along with clinically elevated kinesiophobia, pain catastrophizing, fear of pain, and reduced quality of life. Shoulder pain was statistically associated with pain catastrophizing (ρ = 0.41, p = 0.01). Kinesiophobia positively correlated with fear of pain (ρ = 0.38, p = 0.02) with an inverse relationship to quality of life (ρ = -0.47, p = 0.01). CONCLUSIONS: Elevated pain, and pain-related psychological characteristics, such as catastrophizing and kinesiophobia exist during the early stages after SCI. Early identification of pain-related factors can guide clinical intervention potentially ameliorating pain-linked functional impairments.

Objective: The majority of individuals with spinal cord injury (SCI) experience chronic pain. Chronic pain can be difficult to manage because of variability in the underlying pain mechanisms. More insight regarding the relationship between pain and physical activity (PA) is necessary to understand pain responses during PA. The objective of this study is to explore possible relationships between PA levels and secondary conditions including pain and fatigue.Design: Prospective cohort analysis of a pilot study.Setting: Community.Participants: Twenty individuals with SCI took part in the study, and sixteen completed the study.Interventions: Mobile-health (mHealth) based PA intervention for two-months during the three-month study.Outcome measures: Chronic Pain Grade Scale (CPGS) questionnaire, The Wheelchair User's Shoulder Pain Index (WUSPI), Fatigue Severity Scale (FSS), and PA levels measured by the mHealth system.Results: A positive linear relationship was found between light-intensity PA and task-specific pain. However, the relationship between moderate-intensity PA and pain interference was best represented by a curvilinear relationship (polynomial regression of second order). Light-intensity PA showed positive, linear correlation with fatigue at baseline. Moderate-intensity PA was not associated with fatigue during any phase of the study.Conclusion: Our results indicated that PA was associated with chronic pain, and the relationship differed based on intensity and amount of PA performed. Further research is necessary to refine PA recommendations for individuals with SCI who experience chronic pain.Trial registration: ClinicalTrials.gov identifier: NCT03773692.

STUDY DESIGN: Cohort study. OBJECTIVES: Shoulder pain prevalence is high in those with spinal cord injury (SCI) and is associated with decreased function, participation restrictions and decreased quality of life. Limited evidence exists regarding physical impairments of newly acquired SCI. The current study compared musculoskeletal factors at rehabilitation initiation in individuals with newly acquired SCI to uninjured individuals. We hypothesized no impairment differences of shoulder pain, strength, mobility, muscle extensibility, or rotator cuff integrity would exist between groups. SETTING: Multi-site laboratory setting. METHODS: Thirty-five individuals with newly acquired SCI and age and gender-matched controls without SCI (n = 34) participated. Musculoskeletal Pain Survey, shoulder range of motion (ROM), strength, pectoralis minor muscle extensibility (PM) and tissue integrity [Ultrasound Pathology Rating Scale (USPRS)] were obtained. RESULTS: Higher pain was reported by individuals experiencing new SCI along with lower strength across all bilateral measures, reduced elevation, external rotation, and horizontal adduction ROM, with large effect sizes. PM bilateral extensibility was reduced compared to controls, with moderate between group effect size; however, no USPRS score difference existed. CONCLUSIONS: This study provided the first comprehensive clinical description for individuals with newly acquired SCI. In comparison to matched uninjured controls, participants with new SCI reported greater shoulder pain with impairments in mobility, strength, and extensibility. The identified early clinical impairments aligned with progressive impairment including further pain development and persistence. Awareness and modification of these early clinical impairments may lead to improved long-term outcomes, improving the overall health and well-being of individuals with newly acquired SCI.

Humeral elevation is a critical motion for individuals who use a manual wheelchair given that, in a typical day, wheelchair users reach overhead 5 times more often than able-bodied controls. Kinematic analyses in individuals with chronic spinal cord injury (SCI) have focused on weight-bearing tasks rather than overhead reaching. This technical report presents shoulder movement coordination during overhead reaching in individuals with newly acquired SCI. Eight volunteers with acute SCI and 8 matched, uninjured controls participated. Three-dimensional kinematics were collected during seated, humeral elevation. Scapular and thoracic rotations during humeral elevation were averaged across repetitions. The linear relationship of scapular upward rotation to humeral elevation provided movement coordination analysis. Maximal elevation was reduced in SCI with increased thoracic kyphosis. Medium to large effect sizes were found at each elevation angle, with reduced scapular external rotation, posterior tilt, and increased thoracic kyphosis for those with SCI. The linear relationship occurred later and within a significantly (P = .02) smaller range of humeral elevation in SCI. Altered movement coordination, including a diminished linear association of scapular upward rotation and humeral elevation (scapulohumeral rhythm), is found with reduced maximal elevation and increased thoracic kyphosis during overhead reaching tasks in those with acute SCI.
ABSTRACT
A large peak hip adduction angle during running is a risk factor for several overuse injuries in women. The purpose of this study was to determine if female runners with a large peak hip adduction angle have differences in eccentric hip abductor muscle strength, hip neuromuscular control, and/or hip width to femoral length ratio (HW:FL) compared to those with a small angle. Hip adduction during running, hip strength, hip control, and HW:FL were measured in sixty healthy female runners (1.66 ± 0.06 m; 63.2 ± 8.3 kg; 27 ± 6 years). Data from twenty runners with the largest and twenty with the smallest peak hip adduction angles were analysed. Between-group differences in hip strength, control, and HW:FL were determined using independent t-tests (p < 0.05). Variables that were significantly different between groups were entered into a regression model. Runners in both groups had similar hip strength (p = 0.90) and control (p = 0.65). HW:FL was greater in the large peak angle group (p = 0.04), but only explained a small amount of peak hip adduction angle variance for all sixty runners (R2 = 0.05). Alarge peak hip adduction angle in some healthy female runners may simply be instinctive as there were no deficiencies in the strength or neuromuscular control constructs assessed.

Objective: Limited evidence examines the association of psychological factors, such as fear of movement and pain catastrophizing, with musculoskeletal pain patterns in active manual wheelchair users with spinal cord injury (SCI). This study investigated the relationship among musculoskeletal pain, fear avoidance factors, quality of life (QoL), activity and duration of injury in individuals with SCI. Design: Cross-sectional correlational. Setting: Community setting. Participants: Twenty-six individuals with SCI (age = 42 ± 14 years, duration manual wheelchair use = 17 ± 13 years, work/school/volunteer hours/week = 31 ± 14; recreation/sports hours/week 10 ± 12). Outcome Measures: Demographics and self-report measures including the Musculoskeletal Pain Survey (MPS), Wheelchair Users Shoulder Pain Index (WUSPI), Tampa Scale of Kinesiophobia (TSK-11), Pain Catastrophizing Scale (PCS), Fear of Pain (FPQ), Subjective Quality of Life Questionnaire (SQoL), and the Social Interaction Inventory (SII). Spearman's rho (ρ) assessed correlation among measures. Results: Strong association existed between age and duration of injury (ρ = 0.66, P < 0.001). SQoL offered a strong, direct correlation with age (ρ = 0.63, P = 0.01), duration of injury (ρ = 0.70, P = 0.001), and strong, inverse relationship with MPStotal (ρ = -0.66, P = 0.003) and MPS shoulder subscore (ρ = -0.64, P = 0.004). WUSPI demonstrated strong, inverse association with self-reported work hours (ρ = -0.52, P = 0.02) and a strong, direct relationship to PCS (ρ = 0.79, P = <0001). PCS demonstrated a strong, inverse relationship to work/school/volunteer hours (ρ = 0.71, P < 0.001) and strong association to TSK-11_total (ρ = 0.61, P = 0.001). A moderate, inverse relationship was identified for recreational/sports hours and FPQ (ρ = 0.48, P = 0.03). Conclusion: This cyclical relationship of musculoskeletal pain, reduced activity, and maladaptive psychological factors allude to interdependence of factors, supporting the multidisciplinary approach to care.

BACKGROUND: The purpose of this study was to determine feasibility of further investigation of treatment with instrument-assisted soft-tissue mobilization (IASTM), using the Graston technique, compared with conservative care for treatment of chronic plantar heel pain (CPHP). METHODS: Eleven participants with plantar heel pain lasting 6 weeks to 1 year were randomly assigned to one of two groups, with each group receiving up to eight physical therapy visits. Both groups received the same stretching, exercise, and home program, but the experimental group also received IASTM using the Graston technique. Outcome measures of pain and function were recorded at baseline, after final treatment, and 90 days later. Feasibility of a larger study was determined considering recruitment and retention rates, compliance, successful application of the protocol and estimates of the treatment effect. RESULTS: Both groups demonstrated improvements in current pain (pain at time of survey), pain with the first step in the morning, and function after final treatment and at 90-day follow up. Medium-to-large effect sizes between groups were noted, and sample size estimates demonstrated a need for at least 42 participants to realize a group difference. A larger-scale study was determined to be feasible with modifications including a larger sample size and higher recruitment rate. CONCLUSIONS: This pilot study demonstrates that inclusion of IASTM using the Graston technique for CPHP lasting longer than 6 weeks is a feasible intervention warranting further study. Clinically important changes in the IASTM group and moderate-to-large between-group effect sizes suggest that further research is warranted to determine whether these trends are meaningful.

BACKGROUND: Individuals with short resting pectoralis minor muscle length have been shown to have aberrant scapulothoracic motion when compared to individuals with long resting pectoralis minor muscle length. However, the degree to which the pectoralis minor muscle can be lengthened and whether or not scapulothoracic motion differs between individuals with short and typical resting pectoralis minor muscle length is unknown. OBJECTIVES: To determine if: (1) pectoralis minor muscle elongation (percent pectoralis minor muscle can be actively and passively lengthened beyond resting length), (2) pectoralis minor muscle percent length change during overhead reaching, and (3) scapulothoracic motion during overhead reaching differ between individuals with short and typical resting pectoralis minor muscle length. DESIGN: Two group comparison. METHODS: Thirty healthy individuals were placed into a short or typical resting pectoralis minor muscle length group. A caliper was used to measure resting pectoralis minor muscle length and pectoralis minor muscle length during active and passive muscle lengthening. An electromagnetic tracking system was used to measure pectoralis minor muscle length change as well as scapular, humeral, and trunk motion during several arm elevation tasks. Pectoralis minor muscle elongation and length change during arm elevation tasks were compared between groups using independent t-tests. Two-factor mixed-model analyses of variance were used to compare scapulothoracic motion at arm elevation angles of 30°, 60°, 90°, and 120°. RESULTS: Pectoralis minor muscle elongation and pectoralis minor muscle length change during arm elevation did not differ between groups. Scapulothoracic motion did not differ between groups across arm elevation tasks. CONCLUSIONS: Although resting pectoralis minor muscle length differed between groups, pectoralis minor muscle lengthening and scapulothoracic motion were similar between participants with short and typical resting pectoralis minor muscle length. Additional studies are needed to better understand the role of pectoralis minor muscle elongation on scapulothoracic motion.

OBJECTIVES: To determine (1) agreement of musculoskeletal ultrasound (MSK-US) findings of shoulder pathology and related shoulder special test results in individuals with varied durations of manual wheelchair (MWC) use after spinal cord injury (SCI); and (2) whether shoulder musculoskeletal impairments, per MSK-US and clinical examination, differed in individuals with SCI and varying durations of MWC use. DESIGN: Cross-sectional cohort study. SETTING: Laboratory setting. PARTICIPANTS: Adult volunteers (N=23) with SCI who used an MWC for community mobility. Individuals were stratified into 3 groups based on duration of MWC use: <5 years, 5 to 15 years, and >15 years. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Special tests for shoulder impingement and bicipital tendonitis were performed. Bilateral shoulder MSK-US was performed, with the Ultrasound Shoulder Pathology Rating Scale (USPRS) quantifying biceps tendon, supraspinatus tendon, and greater tuberosity cortical surface impairments. RESULTS: No agreement was found between MSK-US and related special tests. Special tests failed to identify impairment in 33.3% to 100% of those identified on MSK-US. The total USPRS score was highest in those with >15 years' MWC use. A higher proportion of dynamic impingement (supraspinatus and biceps) was found in those with >15 years' MWC use, with other MSK-US items having moderate effect sizes among duration-use groups. CONCLUSIONS: MSK-US identified shoulder impairments more frequently than commonly used special tests. A significant increase in the presence of MSK-US shoulder impairments was identified in the longest-duration group. This was not the case for special tests or pain. MSK-US is an easily administered, low-cost, noninvasive method for determining shoulder impairments and should be used in routine screening of individuals who use an MWC after SCI.

STUDY DESIGN: Prospective cohort correlation study. INTRODUCTION: There is no known published research on correlations between the Patient-Specific Functional Scale (PSFS), hand grip strength, and the Disability of the Arm, Shoulder and Hand (DASH) in a population with hand osteoarthritis (OA). PURPOSE: The purpose of this study is to establish reliability of the PSFS and to evaluate the relationship between the PSFS, hand grip strength, and the DASH for a population with hand OA. METHODS: Thirty-five participants in 4 hand clinics completed the PSFS, hand grip strength testing, and the DASH at the onset of therapy and at discharge. Eighteen participants enrolled at the primary investigator's site completed a baseline PSFS one week before the pretreatment collection with data used to establish relative and absolute reliability. Data were analyzed separately at pretreatment and posttreatment with Spearman's rho correlation (P < .05). Intraclass correlation (2, 1), standard error of the measurement, and minimum detectable change (MDC90 and MDC95) were calculated from the repeated baseline and pretreatment PSFS. RESULTS: Intraclass correlation for PSFS was (r = 0.80) with the standard error of the measurement = 0.56, MDC90 = 1.30, and MDC95 = 1.56. Small correlation between the PSFS and DASH scores was found pretreatment (ρ = -0.10) and change scores (ρ = 0.13). CONCLUSION: Excellent reliability with small measurement error has established clinical utility of the PSFS for the population with hand OA. These outcome measures were shown to measure different constructs and therefore should not be used interchangeably. LEVEL OF EVIDENCE: 3.
