RESUMO
This study aimed to develop and evaluate the ARM (arm repetitive movement) algorithm using inertial measurement unit (IMU) data to assess repetitive arm motion in manual wheelchair (MWC) users in real-world settings. The algorithm was tested on community data from four MWC users with spinal cord injury and compared with video-based analysis. Additionally, the algorithm was applied to in-home and free-living environment data from two and sixteen MWC users, respectively, to assess its utility in quantifying differences across activities of daily living and between dominant and non-dominant arms. The ARM algorithm accurately estimated active and resting times (>98%) in the community and confirmed asymmetries between dominant and non-dominant arm usage in in-home and free-living environment data. Analysis of free-living environment data revealed that the total resting bout time was significantly longer (P = 0.049) and total active bout time was significantly shorter (P = 0.011) for the non-dominant arm. Analysis of active bouts longer than 10 seconds showed higher total time (P = 0.015), average duration (P = 0.026), and number of movement cycles per bout (P = 0.020) for the dominant side. These findings support the feasibility of using the IMU-based ARM algorithm to assess repetitive arm motion and monitor shoulder disorder risk factors in MWC users during daily activities.

Spinal cord injury causes temporary or permanent loss of motor, sensory, or autonomic functions, leading to long-term impairments that are not only confined to physical attributes but also restrict individuals' participation in major domains of life. Around 60%-80% of individuals with spinal cord injuries depend on a wheelchair for mobility. Numerous studies have reported yoga's beneficial role in alleviating spinal cord injury symptoms; however, a validated wheelchair-based yoga module was unavailable. Thus, the present study aimed to develop and validate a wheelchair-based yoga module that comprises a printed protocol for individuals with paraplegia. The study was conducted in four phases: The first three phases were the steps for the formulation of a wheelchair-based yoga module, and in the last phase the content validity of the designed module was determined by a panel of 10 experts, who were asked to rate the preliminary module for its necessity and relevance using a Likert scale. A total of 17 yoga practices with high content validity were included in the final wheelchair-based yoga module, and 10 practices with lower content validity were excluded from the designed module. Data analysis revealed the mean content validation index of the designed module to be 0.81. This study concludes that the formulated wheelchair-based yoga module is valid for individuals with paraplegia. However, future studies need to be conducted to determine the protocol's feasibility and effectiveness.

Importance: Several diseases and conditions, such as cerebrovascular disease, arthritis, previous fractures, neurological diseases, or amputation, can result in severe immobility justifying wheelchair use for increased mobility. Immobility results in disuse osteoporosis and is considered a risk factor for fracture, although there are no large cohort studies that have investigated fracture risk in patients who use wheelchairs compared with an ambulatory control group. Objective: To investigate whether immobilized adults who used wheelchairs had a different risk of fracture and injurious falls compared with matched ambulatory controls. Design, Setting, and Participants: This retrospective cohort study compared patients who used wheelchairs and controls (propensity score matched 1:1 using 22 variables relating to anthropometrics, general condition, comorbidity, and fall and fracture risk), identified through a national database of adults 65 years or older who underwent a health evaluation (baseline) at Swedish health care facilities. Patients were followed up from January 1, 2007, to December 31, 2017, and data analysis was performed between June 1 and 30, 2022. Main Outcomes and Measures: Incident fracture, injurious falls without fracture, and deaths. Results: A total of 55 442 adults using wheelchairs were included in the analysis (mean [SD] age, 83.2 [8.3] years; 60.5% women). Those who used wheelchairs and the 55 442 matched controls were followed up for a median of 2.0 (IQR, 0.5-3.2) and 2.3 (IQR, 0.8-3.6) years, respectively. Patients who used wheelchairs had a lower risk of any fracture (hazard ratio [HR], 0.43 [95% CI, 0.41-0.44]), major osteoporotic fracture (HR, 0.32 [95% CI, 0.31-0.33]), and hip fracture (HR, 0.30 [95% CI, 0.28-0.32]) compared with the ambulatory controls, associations that were only marginally affected by multivariable (same as the matching variables) adjustment. The risk of fall injury was lower among those who used wheelchairs than among ambulatory controls (unadjusted HR for Cox proportional hazards models, 0.48 [95% CI, 0.47-0.50]) and remained highly similar after adjustments. Patients who used wheelchairs had a significantly increased risk of death (HR, 1.35 [95% CI, 1.33-1.36]) compared with controls. Association between wheelchair use and fracture outcomes and injurious falls, calculated using a Fine and Gray model with death as a competing risk, was similar to associations obtained using Cox proportional hazards regression for all fracture outcomes. Conclusions and Relevance: In this retrospective cohort study of older adults, wheelchair use was associated with a lower risk of fracture than observed in ambulatory controls. These findings suggest that immobility associated with wheelchair use should not be considered a risk factor for fracture.

ABSTRACT: The purpose of this review was to understand the research on carpal tunnel syndrome in athletes who compete in wheelchair sport. Eight articles were identified using the search strategy. The most common sport evaluated was wheelchair basketball ( N = 4). Most athletes were male and were diagnosed with a spinal cord injury. Different clinical and electrodiagnostic criteria have been used to diagnose carpal tunnel syndrome. Two studies incorporated ultrasound into the clinical evaluation of median nerve pathology. The duration of disability and wheelchair use were associated with increased risk of carpal tunnel syndrome in four studies. There was no association between training load and the prevalence of carpal tunnel syndrome. No study has explored the functional implications of carpal tunnel syndrome on sports participation and performance. No study has assessed the prevention and treatment of carpal tunnel syndrome in individuals who compete in wheelchair sport. This review provides an understanding of the important diagnostic tools, and demographic and training risk factors to consider when evaluating para-athletes for carpal tunnel syndrome and highlights areas for future research.

Objective: To investigate the progression of rotator cuff tendon pathology across one year in manual wheelchair (MWC) users with spinal cord injury (SCI) and matched able-bodied individuals, and to explore the association between pain, age, and duration of wheelchair use with the progression of rotator cuff pathology.Design: Longitudinal cohort study, 1-year follow-up.Setting: Outpatient clinic at a tertiary medical center.Participants: Twenty-four adult MWC users with SCI (20 men) with an average age (SD) of 37(12) years and 24 age and sex-matched able-bodied individuals.Interventions: Not applicable.Main outcome measure(s): Presence of shoulder pain was collected. Magnetic resonance imaging (MRI) abnormalities of rotator cuff tendons including tendinopathy and tendon tears at baseline and 1-year follow-up visits were graded by a board-certified musculoskeletal radiologist, and three categories of tendon pathology scores including individual tendon scores, unilateral cuff scores, and bilateral cuff scores were calculated for each participant.Results: Fifty-four percent of the MWC users reported shoulder pain at both time points which was significantly higher than able-bodied cohort at baseline (17%, P = 0.012) and year 1 (21%, P = 0.021). Rotator cuff tendon pathology was detected as mainly mild tendinopathies and low-grade partial-thickness tears in both cohorts at both time points but was more common in MWC users. The results for the bilateral cuff scores indicated a significant (P < 0.008) progression of rotator cuff tendon pathology in the MWC users over one year. MRI findings did not change significantly for the able-bodied cohort across time. There was no association of pain, age, or duration of MWC use with progression of rotator cuff pathology in MWC user cohort.Conclusion: MWC users had a higher prevalence of pain than matched able-bodied cohort, but pain was minimal and not function-limiting. Bilateral cuff TOTAL scores showed pathology progression in MWC users, but MRI findings remained stable in the able-bodied cohort. MWC users were 3.4 times more likely to experience pathology progression than the able-bodied cohort.

BACKGROUND: Manual wheelchair users are at high risk of developing shoulder pain. However, it is not known if restrictions to limit the spread of the COVID-19 virus affected physical activity, wheelchair use and shoulder pain. OBJECTIVE: The aim of the study is to determine whether COVID-19 related restrictions caused changes in physical activity levels and the presence of shoulder pain in persons who use a wheelchair. METHODS: Manual wheelchair users completed a survey about the presence and severity of shoulder pain in a cross-sectional study design. Participants completed the Leisure Time Physical Activity Questionnaire and were asked about daily wheelchair activity before and during lockdown. A logistic regression examined the relationship between increase in shoulder pain severity and change in activity levels. RESULTS: Sixty respondents were included for analysis. There was no significant change in physical activity during lockdown. There was a significant reduction in number of hours of daily wheelchair use and number of chair transfers during lockdown. Of the respondents, 67% reported having shoulder pain and 22% reported their shoulder pain becoming more severe during lockdown. No significant relationship was observed between the change in activity levels and increasing severity of shoulder pain. CONCLUSION: Restrictions to reduce the spread of the COVID-19 virus resulted in no changes in physical activity levels in a sample of adult manual wheelchair users; however, there was a reduced time using a wheelchair each day and fewer chair transfers. The changes in wheelchair activities were not related to the worsening of shoulder pain.

OBJECTIVE: Pressure injuries in people with spinal cord injury or dysfunction (SCI/D) are known to have a high recurrence rate. As a countermeasure, we perform surgery after adjusting the wheelchair and cushion with the intervention of a seating expert. The effectiveness of seating interventions in postsurgical recurrence prevention was examined. MATERIALS AND METHODS: In this retrospective analysis, the participants were 19 patients with SCI/D who underwent pressure injury surgical treatment in the gluteal region from 2005 to 2018. The patients with conventional rehabilitation were assigned to Group 1 (n = 8), and those with seating intervention by experts in addition to conventional rehabilitation were assigned to Group 2 (n = 11). The main outcome measure was the presence or absence of recurrence 3 years after the surgery. The recurrence rate was compared between the two groups. RESULTS: The recurrence rates were 18% with seating intervention and 75% without; there was a significant difference (p = 0.025). The recurrence odds ratio was 13.5. CONCLUSION: This study suggests that presurgical seating evaluation and assessment by experts, postsurgical rehabilitation based on presurgical evaluation and assessment, and routine follow-up and seating adjustment according to changes are efficacious for preventing postsurgical pressure injury recurrence in patients with SCI/D.

BACKGROUND: Level and non-level transfers are essential tasks of daily living for wheelchair users. Minimal research has examined the role of shoulder pain and fear of falling on transfer quality. The purpose of this study is to (1) examine the association between shoulder pain, fear of falling (FoF) and transfer quality and (2) explore the feasibility of assessing non-level transfers to-and-from the floor. METHODS: Cross-sectional design was used to explore shoulder pain, FoF, and transfer quality in 30 manual wheelchair users (aged 18-42; 15 males). Participant demographic information (age, sex, race, disability, and years using wheelchair), Spinal Cord Injury-Fall Concern Scale (SCI-FCS), and Wheelchair User Shoulder Pain Index (WUSPI) was collected. Three types of transfers: (1) level, (2) uphill, and (3) floor-to-table were graded by a trained researcher using the Transfer Assessment Instrument (TAI) 3.0. Kruskal-Wallis test was used to determine differences in transfer quality based on condition. Spearman correlation was used to determine associations between demographic data, WUSPI, SCI-FCS, and transfer quality scores. RESULTS: All participants safely completed the uphill non-level transfer; 27 safely completed the floor-to-table non-level transfer. Statistical analysis revealed no difference in TAI score across transfer conditions. Spearman correlation revealed a significant correlation between WUSPI and SCI-FCS scores (r = .68, P = .01) and WUSPI and uphill TAI scores (r = -.45, P = .01). CONCLUSION: Increases in shoulder pain are related to decreased uphill transfer quality and increased FoF. Non-level transfers to-and-from the floor are feasible within clinical or laboratory settings.

Context/Objective: Wheelchair users with spinal cord injury (SCI) have a high risk of developing shoulder pain, caused by rotator cuff disease. Platelet-rich plasma (PRP) is a potential treatment after conservative treatments fail and prior to surgical intervention; however, it has not been tested in wheelchair users who have recalcitrant shoulder pain associated with rotator cuff disease. The objective of this pilot project was to test the safety and potential treatment effect of an ultrasound-guided PRP injection for shoulder pain in the aforementioned population.Design: Prospective, quasi-experimental.Setting: Clinical research center.Participants: Six wheelchair users with SCI (3 paraplegia, 3 tetraplegia) who had chronic shoulder pain due to rotator cuff disease (presence of anterior shoulder pain, positive physical examination tests for rotator cuff disease, and tendinopathy demonstrated by ultrasound) and failed at least six months of conservative treatment.Interventions: Ultrasound-guided PRP injection into pathological shoulder tendons, targeting the supraspinatus. Subjects were provided a standardized stretching and strengthening program and were followed for 4, 8, 12, and 24 weeks post-intervention with outcomes collected at each time-point.Outcome Measures: Wheelchair User's Shoulder Pain Index (WUSPI); pain Numerical Rating Scale (NRS); physical and ultrasound examinations for supraspinatus tendinopathy; 5-point patient global impression of change (PGIC).Results: WUSPI (69.9%, P < 0.001), NRS (49.6%, P < 0.01), and physical exam scores (35.7%, P < 0.01) decreased 24 weeks after treatment. Participants reported overall improvement in their status as a result of the treatment. No adverse events were noted, and no changes in ultrasound markers for tendinopathy were observed.Conclusion: A single, ultrasound-guided PRP injection into the supraspinatus tendon, followed by a stretching and strengthening exercise program, was safe and provided improvements in shoulder pain outcome measures in this sample for 24 weeks. Lack of blinding, short-term follow-up, and a suitable control group warrant a larger randomized controlled trial.Trial Registration: NCT01355549.

Objective: Determine the prevalence of lateral epicondylosis (LE) of the dominant elbow in manual wheelchair users based on ultrasound assessment and physical exam.Design: Prospective, cross-sectional.Setting: National Veteran Wheelchair Games 2018 and 2019 (event medical services).Participants: Manual wheelchair users who attended the National Veteran Wheelchair Games (n = 87).Interventions: Participants completed a questionnaire then underwent an ultrasound assessment and a physical exam of their dominant arm evaluating for common extensor tendinopathy (CET) or clinically LE.Main Outcome Measure: Prevalence of CET diagnosed by ultrasound criteria was compared with other diagnostic criteria with MaNemar test for paired binary data.Results: Forty-six percent (N = 40) of participants met diagnostic criteria for CET by ultrasound assessment and 17% (N = 15) of participants met criteria for LE based on physical exam. These values are dramatically higher than what has been reported in the able-bodied population where the prevalence is estimated to be <2%. Age and number of years of wheelchair use were significant predictors of ultrasound diagnosis of LE (P = 0.02, 95% confidence interval [CI] 1.01-1.11) and (P = 0.05, 95% CI 1.00-1.09), respectively. Association analysis based on odds ratio and CI found no association between ultrasound findings suggestive of LE with regular adaptive sport participation greater than 1.5 h per week.Conclusion: Compared to able-bodied population, there is an increased prevalence of both CET and LE in manual wheelchair users based on either ultrasound assessment or physical exam. CET is associated with increased age and increased years using a manual wheelchair. There is no association between the diagnosis of LE and participation in adaptive sport.

PURPOSE: This purpose was to investigate developed seat-cover assemblies' effect on decreasing the fluctuation of the shear force exerted onto the buttocks as the factors causing decubitus ulcers when the back-support was inclined. MATERIALS AND METHODS: The participants were 10 wheelchair users. The force plate was used to measure the horizontal force as the shear force. The back-support was inclined at increasing angles, starting from the upright position (IUP), then proceeding to a fully reclined position (FRP), and returning to the upright position (RUP). The experimental conditions were two conditions; the seat-cover assembly conditions and without the seat-cover assembly as the control conditions. RESULTS: The average values in the seat-cover assembly condition were 14.4 ± 3.3, 13.9 ± 2.3, and 17.3 ± 3.3% body weight in the IUP, FRP, and RUP, respectively. The average values in the control condition were 14.8 ± 2.6, 11.4 ± 1.7, and 24.0 ± 6.7% body weight in the IUP, FRP, and RUP, respectively. In the FUP and the RUP, there were significant differences between two conditions (p < .01). CONCLUSION: These results suggested that the shear force exerted onto the buttocks may to be decreased by using novel seat-cover assembly.Implications for rehabilitationIt is possible to decrease the fluctuations in the shear force by moving the body up and down according the novel seat-cover assembly attached the back-support incline.Disabled, older individuals can be provided with a comfortable life on a reclining wheelchair while preventing decubitus ulcers.

BACKGROUND: Shoulder pain is one of the most common musculoskeletal concerns in manual wheelchair users including among athletes. However, there is a paucity of research characterizing both shoulder pain and shoulder pathology in this population. OBJECTIVE: To characterize and compare the prevalence of current shoulder pain and ultrasound metrics of shoulder pathology between wheelchair athletes, nonathletic wheelchair users, and nonwheelchair users. DESIGN: Cross-sectional. SETTING: Chicago-area adaptive sport teams/programs and musculoskeletal clinics. PARTICIPANTS: Thirty-four wheelchair athletes, six nonathletic wheelchair users, and 12 nonwheelchair users. METHODS: Self-reported shoulder pain was assessed by questionnaire and Wheelchair User Shoulder Pain Index (WUSPI). Shoulder physiology and pathology were assessed by physical and ultrasound evaluation of both shoulders by a sports medicine physician. MAIN OUTCOME MEASURES: Questionnaire outcomes: Prevalence of current shoulder pain, total WUSPI score. Physical examination outcomes: total Physical Examination of Shoulder Scale (PESS) score. Sonographic outcomes: Acromiohumeral distance (AHD) and presence of shoulder pathology. RESULTS: The majority of wheelchair athletes (68%) and nonathletic wheelchair users (67%) experienced shoulder pain since using a manual wheelchair. Wheelchair basketball players had a mean WUPSI score of 17.2 (SD = 21.8), and athletes participating in handcycling, sled hockey, and quad rugby had mean scores of 4.91 (SD = 8.32), 7.76 (SD = 13.1), and 4.29 (SD = 7.75), respectively. Shoulder pathology was observed in 14 of 31 (45%) wheelchair athletes and 4 of 6 (67%) nonathletic wheelchair users (p = .41). CONCLUSIONS: Although wheelchair use is a risk factor for shoulder pain, participation in amateur wheelchair sports may not be associated with increased risk of shoulder pain. It is possible that overhead sports such as wheelchair basketball may define a unique high-risk group. Further study is needed to examine this relationship and to determine whether there are differences between specific wheelchair sports.

OBJECTIVE: To describe the number, specifics and co-occurrence of shoulder pathologies detected by MRI in manual wheelchair users with spinal cord injury and to evaluate the association between shoulder pathologies and presence of shoulder pain. DESIGN: Cross-sectional observation study. SETTING: Community. PARTICIPANTS: Fifty-one wheelchair-dependent persons with spinal cord injury (44 males, 7 females, median age 50 years (IQR 14), median time since injury 24 years (IQR 16)) were allocated to pain or no-pain group based on the Wheelchair User Shoulder Pain Index. INTERVENTIONS: Not applicable. OUTCOME MEASURES: All persons underwent shoulder MRI. Pathologies were scored blinded by two experienced radiologists. Participant characteristics, number and severity of shoulder pathologies were analyzed descriptively. Logistic regression was performed to evaluate the association between MRI findings and shoulder pain. RESULTS: The median number of co-occurring MRI findings per person ranged from 0 to 19 (out of 31 possible findings). The cluster of MRI findings occurring most often together were tendon tears of supraspinatus (present in 84%), subscapularis (69%) and biceps (67%) and osteoarthritis of acromioclavicular joint (80%). When correcting for age and time since injury, the logistic regression showed no statistically significant correlation between the individual pathologies and shoulder pain. CONCLUSION: MRI findings of shoulder pathology are very frequent in persons with and without shoulder pain. Therefore, when diagnosing the cause of shoulder pain and planning interventions, health care professionals should keep this finding in mind and MRI should not be interpreted without careful consideration of clinical history and functional testing.

Objective: To investigate the prevalence of rotator cuff and long head of the biceps pathologies in manual wheelchair (MWC) users with spinal cord injury (SCI).Design: Cross-sectional study.Setting: Outpatient clinic at a tertiary medical center.Participants: Forty-four adult MWC users with SCI (36 men and 8 women) with an average age (SD) of 42 (13) years. SCI levels ranged from C6 to L1; complete and incomplete SCI.Outcome Measures: Participants' demographic and anthropometric information, presence of shoulder pain, Wheelchair User's Pain Index (WUSPI) scores, and magnetic resonance imaging findings of shoulder pathologies including tendinopathy, tendon tears, and muscle atrophy.Results: Fifty-nine percent of the participants reported some shoulder pain. The prevalence of any tendinopathy across the rotator cuff and the long head of biceps tendon was 98%. The prevalence of tendinopathy in the supraspinatus was 86%, infraspinatus was 91%, subscapularis was 75%, and biceps was 57%. The majority of tendinopathies had mild or moderate severity. The prevalence of any tears was 68%. The prevalence of tendon tears in the supraspinatus was 48%, infraspinatus was 36%, subscapularis was 43%, and biceps was 12%. The majority of the tears were partial-thickness tears. Participants without tendon tears were significantly younger (P < 0.001) and had been wheelchair user for a significantly shorter time (P = 0.005) than those with tendon tears.Conclusion: Mild and moderate shoulder tendinopathy and partial-thickness tendon tears were highly prevalent in MWC users with SCI. Additionally, the findings of this study suggest that strategies for monitoring shoulder pathologies in this population should not be overly reliant on patient-reported pain, but perhaps more concerned with years of wheelchair use and age.

BACKGROUND: Individuals with spinal cord injury (SCI) who use manual wheelchairs (MWCs) have a higher rate of rotator cuff pathology progression than able-bodied individuals. OBJECTIVES: This study aimed to test the ability of risk and recovery metrics of arm use to differentiate between (1) MWC users with SCI and matched able-bodied participants (cross-sectional matched-sample study) and (2) MWC users with rotator cuff pathology progression over 1 year from those without pathology progression (longitudinal study). METHODS: Thirty-four MWC users and 34 age- and sex-matched able-bodied individuals were recruited. Upper arm risk (humeral elevation >60°) and recovery (static ≥5 seconds and humeral elevation <40°) metrics were calculated from wireless inertial measurement units (IMUs) worn on the upper arms and torso in the free-living environment. Two separate magnetic resonance imaging studies were completed and assessed for a subset of 16 MWC users approximately 1 year apart. RESULTS: The frequency of risk events (p = .019), summated duration of recovery events (p = .025), and duration of each recovery event (p = .003) were higher for MWC users than able-bodied participants. The summated duration of risk events (p = .047), frequency of risk events (p = .027), and risk to recovery ratio (p = .02) were higher and the summated duration of recovery events (p = .036) and frequency of recovery events (p = .047) were lower for MWC users with rotator cuff pathology progression (n = 5) compared to those without progression (n = 11). CONCLUSION: IMU-derived metrics quantifying arm use at postures >60° and risk to recovery ratios may provide insights of potential risk factors for rotator cuff pathology progression.

CONTEXT/OBJECTIVES: Wheelchair users with chronic shoulder pain have few options after conservative treatments fail. This pilot study's purpose was to establish safety and treatment effects of micro-fragmented adipose tissue (MFAT) injections under ultrasound guidance for treatment of refractory shoulder pain caused by rotator cuff disease in wheelchair users with spinal cord injury (SCI) to prepare for a larger trial. DESIGN: Pilot clinical trial. SETTING: Rehabilitation hospital outpatient clinic. PARTICIPANTS: Ten wheelchair users with chronic SCI who had moderate-to-severe shoulder pain caused by refractory rotator cuff disease (diagnosed via ultrasound) for greater than 6 months. INTERVENTIONS: Ultrasound-guided injections of MFAT into the pathologic rotator cuff tendons and other abnormal shoulder structures (e.g. acromioclavicular and glenohumeral joints; subacromial bursa). OUTCOME MEASURES: 6- and 12-month changes in 11-point Numerical Rating Scale (NRS); Wheelchair User's Shoulder Pain Index (WUSPI); Brief Pain Inventory pain interference items (BPI-I7); Patient Global Impression of Change (PGIC); ultrasound and physical exams; and adverse events. CONCLUSIONS: There were no significant adverse events throughout the study period. WUSPI, NRS, and BPI-I7 scores were significantly lower 6 and 12 months post-procedure (P < .05). Of those who remained in the trial, clinically meaningful changes (≥30% decrease) in WUSPI, NRS, and BPI-I7 scores were observed in 77.8%, 77.8%, and 66.7% of participants, respectively. All but one participant reported improvement in clinical status. MFAT injection under ultrasound guidance is potentially a safe and efficacious treatment for refractory shoulder pain caused by rotator cuff disease in wheelchair users with SCI. A larger, randomized controlled trial has been initiated.Trial registration: ClinicalTrials.gov identifier: NCT03167138.

Shoulder pain and pathology are extremely common for individuals with spinal cord injuries (SCI) who use manual wheelchairs (MWC). Although risky humeral kinematics have been measured during wheelchair-based activities performed in the lab, little is known about arm kinematics in the free-living environment. The purpose of this study was to measure the humeral elevation workspace throughout a typical day for individuals with SCI who use a MWC and matched able-bodied controls. Thirty-four individuals with SCI who use a MWC (42.7±12.7 years of age, 28 males/6 females, C6-L1) and 34 age-and sex-matched controls were enrolled. Participants wore three inertial measurement units (IMU) on their upper arms and torso for one to two days. Humeral elevation angles were estimated and the percentage of time individuals spent in five elevation bins (0-30°, 30-60°, 60-90°, 90-120°, and 120-180°) were calculated. For both arms, the SCI cohort spent a significantly lower percentage of the day in 0-30° of humeral elevation (Dominant: SCI = 15.7±12.6%, Control = 32.1±15.6%, p<0.0001; Non-Dominant: SCI = 21.9±17.8%, Control = 34.3±15.5%, p = 0.001) and a significantly higher percentage of time in elevations associated with tendon compression (30-60° of humeral elevation, Dominant: SCI = 62.8±14.4%, Control = 49.9.1±13.0%, p<0.0001; Non-Dominant: SCI = 58.8±14.9%, Control = 48.3±13.6%, p = 0.003) than controls. The increased percentage of time individuals with SCI spent in elevations associated with tendon compression may contribute to increased shoulder pathology. Characterizing the humeral elevation workspace utilized throughout a typical day may help in understanding the increased prevalence of shoulder pain and pathology in individuals with SCI who use MWCs.

PURPOSE: Nursing home residents sit in wheelchairs (WCs) for extended periods, often with slumped posture. They often experience pneumonia, pressure ulcers, and pain. This study described WC seated posture with its selected predictors and outcomes in the nursing home environment, throughout the daytime hours of 1 day. DESIGN AND METHODS: This observational study (n = 45) in two Veterans Administration Community Living Centers introduced a new measure of WC fit and described WC seated posture of older Veterans, with selected predictors and outcomes. FINDINGS: Wheelchair seated posture was predicted by cognitive status, WC fit, WC skills, and duration of sitting, but not by level of sitting ability. Poor posture measured by the Seated Posture Scale was associated with pain. Highest interface pressures measurable were seen in peak pressure index (PPI = 200 mm Hg), indicating risk of pressure injury. Veterans often denied discomfort, possibly lowering overall pain scores, while reporting severe pain in specific body parts. CONCLUSIONS: Wheelchair seated posture was predicted by cognitive status, WC fit, WC skills, and duration of sitting. Poor posture was associated with pain, and poor posture was an outcome of poor WC fit. Poor WC fit in this study supported earlier findings in non-Veterans Administration nursing homes.

STUDY DESIGN: Secondary analysis of a cross-sectional observation study. OBJECTIVES: To determine the relationship between skin ultrasound images and muscle damage in wheelchair basketball athletes, using skin blotting examinations of the ischial regions. SETTING: Community, Japan. METHODS: Fourteen elite wheelchair basketball athletes were recruited. We obtained data regarding participants' characteristics. We undertook ultrasonographic images and quantitative skin blotting of the ischial region before and after training, and after rest. RESULTS: We identified Category II and III pressure injuries in 2 of the 12 participants. Structural features were classified into four categories based on ultrasonographic features, namely, normal skin structure, unclear superficial and deep fascia, cloudy fat layer, and fat infiltration and low-echoic lesion/anechoic lesions. The muscle-type creatinine kinase (CK-M) level (median [interquartile range: IQR], 2.98 [2.80-3.47]) in the fat infiltration and low-echoic lesion/anechoic lesion group was significantly higher (1.43 [1.41-1.49]) than in a nonfat infiltration and low-echoic lesion/anechoic lesion group after training (p = 0.03). The interleukin-6 (IL-6) level (median [IQR], 23.5 [16.15-58.97]) in the fat infiltration and low-echoic lesion/anechoic lesion group was significantly higher (1.94 [1.74-4.44]) than in the nonfat infiltration and low-echoic lesion/anechoic lesion group after rest (mean difference = -25.4, 95% CI -61.1 to 10.7, p = 0.03). CONCLUSIONS: The combination of ultrasonographic images and skin blotting using CK-M and IL-6, could detect early deep tissue damage in wheelchair athletes. These techniques could be potentially useful in the treatment and prevention of pressure injuries. SPONSORSHIP: This study was supported in part by YAMAHA Motor Foundation for Sports.
