Hand Flexor Tendon Repair: From Biology to Surgery and Rehabilitation.

Tendon biology and anatomy are crucial to manage hand flexor tendon injuries, not only for surgical treatment but also for rehabilitation; surgeon and physical therapist have to choose zone by zone the best way to manage and restore the normal function of hand flexor tendons.

[Exploration of family rehabilitation model for children with scar contracture after hand burns].

Objective: To explore the family rehabilitation model for children with scar contracture after hand burns and observe its efficacy. Methods: A retrospective non-randomized controlled study was conducted. From March 2020 to March 2021, 30 children with scar contracture after deep partial-thickness to full-thickness burns of hands, who met the inclusion criteria, were hospitalized in the Burn Center of PLA of the First Affiliated Hospital of Air Force Medical University. According to the rehabilitation model adopted, 18 children (23 affected hands) were included in a group mainly treated by family rehabilitation (hereinafter referred to as family rehabilitation group), and 12 children (15 affected hands) were included in another group mainly treated by hospital rehabilitation (hereinafter referred to as hospital rehabilitation group). In the former group, there were 11 males and 7 females, aged (4.8±2.1) years, who began rehabilitation treatment (3.1±0.8) d after wound healing; in the latter group, there were 7 males and 5 females, aged (4.6±2.1) years, who began rehabilitation treatment (2.8±0.7) d after wound healing. The children in hospital rehabilitation group mainly received active and passive rehabilitation training in the hospital, supplemented by independent rehabilitation training after returning home; after 1-2 weeks of active and passive rehabilitation training in the hospital, the children in family rehabilitation group received active and passive rehabilitation training at home under the guidance of rehabilitation therapists through WeChat platform. Both groups of children were treated for 6 months. During the treatment, they wore pressure gloves and used hand flexion training belts and finger splitting braces. Before treatment and after 6 months of treatment, the modified Vancouver scar scale, the total active movement of the hand method, and Carroll quantitative test of upper extremity function were used to score/rate the scar of the affected hand (with the difference of scar score between before treatment and after treatment being calculated), the joint range of motion (with excellent and good ratio being calculated), and the function of the affected limb, respectively. Data were statistically analyzed with independent sample t test, equivalence test, Fisher's exact probability test, and Mann-Whitney U test. Results: The differences of scar scores of the affected hands of children in family rehabilitation group and hospital rehabilitation group between after 6 months of treatment and those before treatment were 3.0 (2.0, 7.0) and 3.0 (2.0, 8.0) respectively (with 95% confidence interval of 2.37-5.38 and 1.95-5.91). The 95% confidence interval of the difference between the differences of the two groups was -2.43-2.21, which was within the equivalent boundary value of -3-3 (P<0.05). The excellent and good ratios of joint range of motion of the affected hand of children in family rehabilitation group and hospital rehabilitation group were 3/23 and 2/15 respectively before treatment, and 15/23 and 12/15 respectively after 6 months of treatment. The ratings of joint range of motion of the affected hand of children in family rehabilitation group and hospital rehabilitation group after 6 months of treatment were significantly higher than those before treatment (with Z values of 3.58 and 2.30, respectively, P<0.05), but the ratings of joint range of motion of the affected hand between the two groups were similar before treatment and after 6 months of treatment (with Z values of 0.39 and 0.55, respectively, P>0.05). The functional ratings of the affected limbs of children in family rehabilitation group and hospital rehabilitation group after 6 months of treatment were significantly higher than those before treatment (with Z values of 3.98 and 3.51, respectively, P<0.05), but the functional ratings of the affected limbs between the two groups were similar before treatment and after 6 months of treatment (with Z values of 1.27 and 0.38, respectively, P>0.05). Conclusions: The WeChat platform assisted rehabilitation treatment with mainly family rehabilitation, combined with hand flexion and extension brace can effectively reduce the scarring after children's hand burns, improve the joint range of motion of the affected hands, and promote the recovery of affected limb function. The effect is similar to that of hospital-based rehabilitation providing an optional rehabilitation, treatment method for children who cannot continue to receive treatment in hospital.

"It was like a bad dream": Making sense of violent hand amputation and replantation in South Africa.

BACKGROUND: South Africa is faced with one of the highest rates of violent crime in the world. Accordingly, therapists treat high numbers of deliberate hand injuries. There is, however, a paucity of literature exploring the lived experiences of these survivors. PURPOSE: The aim of this study was to describe and interpret the meaning of living through a violent hand amputation and replantation, the impact on occupational adaptation and to reflect on therapeutic intervention, within the context of South Africa. STUDY DESIGN: An exploratory embedded single case study using a qualitative approach. METHODS: Interpretative phenomenological analysis was used to analyze data from: 8 interviews with the primary participant, over a period of 33 months; an interview with his work colleague; interviews with 5 health professionals; a review of the occupational therapy rehabilitation file and a review of the audio-visuals, recorded over 2-years. RESULTS: This narrative reveals a man who understood his terrifying assault to be part of a southern African ritual of spiritual origin - using human body parts for traditional medicine (muti crime) or witchcraft. He perceived his expensive hand replantation and therapy as surreal and violence as normal. Challenges highlighted the importance of being attentive to the psychosocial sequelae of violence; and the most valuable part of therapy was perceived as occupational engagement. CONCLUSIONS: The perception of attempted muti murder situates this extreme and unusual case study as a novel contribution to the medical and rehabilitation literature. South African therapists are urged to be actively involved in changing the culture of violence, and hand therapists are reminded of the importance of applying holistic and occupation-based intervention.

Effect of exoskeleton manipulator on hand function rehabilitation for postburn patients.

PURPOSE: Patients with scar contracture deformities caused by hand burns were treated with an exoskeleton manipulator system, which was equipped with games to explore its clinical application value. METHODS: Twenty patients who were treated for post-burn scars of bilateral hands between October 2020 and June 2021 were selected (ChiCTR2000036232). The patients were divided into two groups: control, 10 patients (traditional outpatient treatment); and experimental, 10 patients (exoskeleton manipulator system treatment). We compared the change in the total active motion (TAM) value, grip strength, scar improvement, and postoperative pain improvement. RESULTS: After 3 months of rehabilitation training, the improvement of thumb TAM was 33.80 ± 11.38 ° in the experimental group and 23.2 ± 6.13 ° in the control group. With respect to the index finger TAM, the improvement in the experimental and control groups was 84.50 ± 30.96 ° and 54.80 ± 15.89 °, respectively. The middle finger TAM of the experimental and control groups improved by 86.75 ± 32.85 ° and 60.25 ± 17.97 °, respectively. However, improvement of grip strength, scar score, and pain score were similar between the two groups. CONCLUSIONS: The exoskeleton manipulator system has excellent effects in improving burned hand joint movement, which is suitable for hand burn patients and has beneficial clinical effects.Implications for rehabilitationExercise is an effective means to improve the hand function of burn patients.The application of mechanical devices in the rehabilitation of burned hands can effectively help patients exercise.The A5 Hand Function Training System is an exoskeleton mechanical device that can exercise the small joints of the hand. It assists patients in using different computer games during treatment.

The functional ratings of the affected limbs of children in family rehabilitation group and hospital rehabilitation group after 6 months of treatment were significantly higher than those before treatment (with Z values of 3.98 and 3.51, respectively, P<0.05), but the functional ratings of the affected limbs between the two groups were similar before treatment and after 6 months of treatment (with Z values of 1.27 and 0.38, respectively, P>0.05). Conclusions: The WeChat platform assisted rehabilitation treatment with mainly family rehabilitation, combined with hand flexion and extension brace can effectively reduce the scarring after children's hand burns, improve the joint range of motion of the affected hands, and promote the recovery of affected limb function.

Hand characteristics and functional abilities in predicting return to work in adult workers with traumatic hand injury.

BACKGROUND: Hand injuries affect a person's functioning, thus impeding their abilities to return to work. There is a limited understanding in return to work of the overall predictors when including hand characteristics and functional abilities. Therefore, it is essential to identify the most relevant predictors in return to work among individuals with a hand injury. OBJECTIVES: (1) To compare hand function characteristics and functional abilities of injured workers who have or have not returned to work. (2) To estimate hand function characteristics and functional abilities as predictors to return to work. METHODS: One hundred and fifteen adult workers with hand injuries aged 18- 59 years old from five general hospitals in Malaysia participated in a cross-sectional study. Predictors were estimated using logistic regression. RESULTS: There was a significant association between occupational sector (p = 0.012), injury duration (p = 0.024), occupational performance (p = 0.009) and satisfaction with performance (p < 0.001), grip strength of injured hand (p = 0.045- 0.002) and the Disability of Arm, Shoulder and Hand (DASH) disability/symptom (p = 0.001) with the person's return to work status. Significant predictors of return to work were identified using the Canadian Occupational Performance Measure (COPM) satisfaction's score, DASH disability/symptoms' score and duration of the injury. CONCLUSION: As two main predictors of return to work were COPM satisfaction and DASH disability/symptoms, occupational therapists working in rehabilitation should focus on achieving functional performance and satisfaction within the optimal time.

Simulación clínica para la rehabilitación de la mano en un anestesiólogo después de una lesión ocupacional: un estudio de caso / Patient simulation for hand therapy in an anesthesiologist after an occupational injury: A case study

Describir el uso de la simulación clínica como terapia de rehabilitación de la mano de una paciente anestesióloga que sufrió atrapamiento del pulgar derecho con la mesa quirúrgica y se le realizó un autoinjerto parcial del dedo del pie a la mano.En la semana 14 tras la cirugía se introdujo la terapia de simulación con tareas anestésicas simuladas y escenarios clínicos en lugar de la rehabilitación habitual. Las variables cuantificadas, tanto físicas, como funcionales y psicológicas, indicaron una mejoría durante y después de la intervención con simulación, que se mantuvo un mes después de la vuelta al trabajo.El uso de la simulación clínica en la rehabilitación en una paciente anestesióloga después de una lesión en la mano contribuyó a mejorar la amplitud de movimiento, la fuerza, la sensibilidad y las pruebas funcionales, y jugó un papel determinante en la reincorporación laboral para asumir las demandas de la práctica de la anestesia.(AU)

We described the use of clinical simulation for hand therapy in an anesthesiologist that accidentally suffered from entrapment with the surgical table in the right thumb and underwent a partial toe-to-hand autograft.At week 14 after surgery, the patient practiced anesthetic tasks and clinical scenarios using a patient simulator instead undergoing a regular occupational therapy regimen. Quantifiable physical, functional and psychological measures improved during and after the simulation intervention, and there was no decline one month after the patient returned to work.The use of clinical simulation as part of the rehabilitation process of an anesthesiologist after hand injury contributed to improving the range of motion, strength, sensibility, and functional tests. Overall, it played an important role in determining the worker's potential to withstand the demands of anesthesia practice.(AU)

Printing a static progressive orthosis for hand rehabilitation.

BACKGROUND: Static progressive orthosis is used for the treatment of severe joint contracture after trauma and/or surgery. However, a custom-fabricated static progressive splint would be expensive and labor intensive. Especially, owing to very limited payment under the current Taiwanese National Health Insurance, the incentives to fabricate a patient-specific splint are insufficient for a therapist. To ease splint construction, we introduced three-dimensional (3D)-printed "shark fin"-shaped device works as a static progressive orthosis for the hand rehabilitation. The aim of this study was to describe and demonstrate the newly designed device. METHODS: This study included a 46-year male suffered from a left distal radius fracture and underwent open reduction internal fixation and a 23-year male with the right thumb flexor pollicis longus rupture, requiring tendon repair. Both subjects used this "shark fin"-shaped device to stretch for increasing range of motion (ROM) of wrist extension and the thumb. RESULTS: The patient receiving ulnar shortening surgery used this device to stretch for increasing ROM of wrist extension. The active ROM of wrist extension improved from 30° to 50°. The other patient with the right thumb flexor pollicis longus rupture suffered from thumb contracture; the ROMs of the metacarpophalangeal (MCP) joint and interphalangeal (IP) joint were 40°-55° and 20°-25°, respectively. After tenolysis surgery, his ROMs of the MCP and IP joints were improved to 10°-35° and 40°-65°, respectively. Following physical therapy by applying the device, his ROMs of the MCP and IP joints were further increased to 0°-40° and 25°-70°, respectively. CONCLUSION: Incorporating the "shark fin"-shaped orthosis into hand rehabilitation increased the ROM of wrist extension for a patient with distal radius fracture and improved the ROM of the MCP and IP joints in another patient after tenolysis surgery.

Effects of Virtual Reality and Task-Oriented Training on Hand Function and Activity Performance in Pediatric Hand Burns: A Randomized Controlled Trial.

OBJECTIVE: To assess the efficacy of a motion-sensing, hands-free gaming device and task-oriented training (TOT) programs on improving hand function, activity performance, and satisfaction in pediatric hand burns. DESIGN: A randomized controlled trial. SETTING: Outpatient rehabilitation center. PARTICIPANTS: Fifty children with deep partial-thickness or full-thickness hand burns. (N=50; mean age, 10.70±1.64y; range, 7-14y) INTERVENTIONS: Children were randomized into 1 of the following 3 groups: the motion-sensing, hands-free gaming device group that used interactive video games plus traditional rehabilitation (TR); the TOT group that used real materials plus TR; and the control group that only received TR, all groups received the interventions 3 days per week for 8 weeks. MAIN OUTCOME MEASURES: We assessed the children at the baseline and after 8 weeks of intervention. The primary outcome measures were the Jebsen-Taylor Hand Function Test, Duruoz Hand Index (DHI), and Canadian Occupational Performance Measure (COPM). The secondary outcome measures were range of motion (ROM) of the digits, grip strength, and pinch strengths (tip, palmer, and lateral pinch). RESULTS: There was a significant increase in all measurements of the motion-sensing, hands-free gaming device and TOT groups compared with that of the control group postintervention (P<.05). There was no significant change in Jebsen-Taylor Hand Function Test, COPM performance, ROM, grip strength, and tip and lateral pinch strengths between the motion-sensing, hands-free gaming device group and TOT group (P>.05), whereas there was a significant increase in DHI, COPM satisfaction, and palmer pinch strength (P<.05) in the motion-sensing, hands-free gaming device group compared with the TOT group postintervention. CONCLUSIONS: The motion-sensing, hands-free gaming device and TOT programs resulted in significant improvement in hand function, activity performance and satisfaction, ROM of the digits, grip strength, and pinch strengths in pediatric hand burns compared with the traditional hand rehabilitation.

Rehabilitation following surgery for flexor tendon injuries of the hand.

BACKGROUND: Various rehabilitation treatments may be offered following surgery for flexor tendon injuries of the hand. Rehabilitation often includes a combination of an exercise regimen and an orthosis, plus other rehabilitation treatments, usually delivered together. The effectiveness of these interventions remains unclear. OBJECTIVES: To assess the effects (benefits and harms) of different rehabilitation interventions after surgery for flexor tendon injuries of the hand. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials, the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, MEDLINE, Embase, two additional databases and two international trials registries, unrestricted by language. The last date of searches was 11 August 2020. We checked the reference lists of included studies and relevant systematic reviews. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and quasi-RCTs that compared any postoperative rehabilitation intervention with no intervention, control, placebo, or another postoperative rehabilitation intervention in individuals who have had surgery for flexor tendon injuries of the hand. Trials comparing different mobilisation regimens either with another mobilisation regimen or with a control were the main comparisons of interest. Our main outcomes of interest were patient-reported function, active range of motion of the fingers, and number of participants experiencing an adverse event. DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials for inclusion, extracted data, assessed risk of bias and assessed the quality of the body of evidence for primary outcomes using the GRADE approach, according to standard Cochrane methodology. MAIN RESULTS: We included 16 RCTs and one quasi-RCT, with a total of 1108 participants, mainly adults. Overall, the participants were aged between 7 and 72 years, and 74% were male. Studies mainly focused on flexor tendon injuries in zone II. The 17 studies were heterogeneous with respect to the types of rehabilitation treatments provided, intensity, duration of treatment and the treatment setting. Each trial tested one of 14 comparisons, eight of which were of different exercise regimens. The other trials examined the timing of return to unrestricted functional activities after surgery (one study); the use of external devices applied to the participant to facilitate mobilisation, such as an exoskeleton (one study) or continuous passive motion device (one study); modalities such as laser therapy (two studies) or ultrasound therapy (one study); and a motor imagery treatment (one study). No trials tested different types of orthoses; different orthosis wearing regimens, including duration; different timings for commencing mobilisation; different types of scar management; or different timings for commencing strengthening. Trials were generally at high risk of bias for one or more domains, including lack of blinding, incomplete outcome data and selective outcome reporting. Data pooling was limited to tendon rupture data in a three trial comparison. We rated the evidence available for all reported outcomes of all comparisons as very low-certainty evidence, which means that we have very little confidence in the estimates of effect. We present the findings from three exercise regimen comparisons, as these are commonly used in clinical current practice. Early active flexion plus controlled passive exercise regimen versus early controlled passive exercise regimen (modified Kleinert protocol) was compared in one trial of 53 participants with mainly zone II flexor tendon repairs. There is very low-certainty evidence of no clinically important difference between the two groups in patient-rated function or active finger range of motion at 6 or 12 months follow-up. There is very low-certainty evidence of little between-group difference in adverse events: there were 15 overall. All three tendon ruptures underwent secondary surgery. An active exercise regimen versus an immobilisation regimen for three weeks was compared in one trial reporting data for 84 participants with zone II flexor tendon repairs. The trial did not report on self-rated function, on range of movement during three to six months or numbers of participants experiencing adverse events. The very low-certainty evidence for poor (under one-quarter that of normal) range of finger movement at one to three years follow-up means we are uncertain of the finding of zero cases in the active group versus seven cases in the immobilisation regimen. The same uncertainty applies to the finding of little difference between the two groups in adverse events (5 tendon ruptures in the active group versus 10 probable scar adhesion in the immobilisation group) indicated for surgery. Place and hold exercise regimen performed within an orthosis versus a controlled passive regimen using rubber band traction was compared in three heterogeneous trials, which reported data for a maximum of 194 participants, with mainly zone II flexor tendon repairs. The trials did not report on range of movement during three to six months, or numbers of participants experiencing adverse events. There was very low-certainty evidence of no difference in self-rated function using the Disability of the Arm, Shoulder and Hand (DASH) functional assessment between the two groups at six months (one trial) or at 12 months (one trial). There is very low-certainty evidence from one trial of greater active finger range of motion at 12 months after place and hold. Secondary surgery data were not available; however, all seven recorded tendon ruptures would have required surgery. All the evidence for the other five exercise comparisons as well as those of the other six comparisons made by the included studies was incomplete and, where available, of very low-certainty. AUTHORS' CONCLUSIONS: There is a lack of evidence from RCTs on most of the rehabilitation interventions used following surgery for flexor tendon injuries of the hand. The limited and very low-certainty evidence for all 14 comparisons examined in the 17 included studies means that we have very little confidence in the estimates of effect for all outcomes for which data were available for these comparisons. The dearth of evidence identified in this review points to the urgent need for sufficiently powered RCTs that examine key questions relating to the rehabilitation of these injuries. A consensus approach identifying these and establishing minimum study conduct and reporting criteria will be valuable. Our suggestions for future research are detailed in the review.

The Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) scores in 961 Japanese volunteers.

INTRODUCTION: Patient-reported outcomes recently have been used to assess treatment outcomes. The Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) is a particularly convenient and useful tools. However, data on the normative values of Japanese population are lacking, so the present study was conducted to gather this information. METHODS: We assessed 1098 volunteers over 18 years of age (363 men and 735 women, average 50 years old) who had not received upper limb treatment in a medical facility. These participants included our institution's staff, their family members, and the participants in the group meetings held by institution's staff. Their occupations were also examined. We divided occupations into nonmanual and manual labor. These factors of the participants were then analyzed to clarify which (if any) influenced the QuickDASH. RESULTS: Valid answers were obtained from 961 subjects (87.5%). The median score was 2 (mean: 4.8) in the overall population, 0 (mean: 2.6) in men, and 2.5 (mean: 6.0) in women. The scores increased with age and were higher in women than in men. There were no significant differences by manual labor. Female sex and older age were identified as factors that influenced the QuickDASH score in the multiple regression analysis. There were high correlations among QuickDASH, work and sports/music scores. CONCLUSIONS: The present study provided QuickDASH scores for Japanese volunteers who had not received upper limb treatment in a medical facility. The scores were associated with older age and female sex. This study helps us to know the degree of potential upper limb impairment in the general population, and will help in populational strategies as primary and secondary preventive medicine for upper limb-related diseases.

Advantages and Limitations of Leap Motion from a Developers', Physical Therapists', and Patients' Perspective.

BACKGROUND: Physical rehabilitation exergames (PREGs) are suitable for motivating patients toward completing treatments. Leap Motion (LM) is a motion sensor that may be useful for developing PREGs targeted at hands and fingers rehabilitation. Therefore, knowing the advantages and limitations of LM is relevant to understand under which conditions this sensor may be suitable. OBJECTIVE: In this article, we present a qualitative study to identify the main advantages and limitations of LM for PREGs. METHODS: We collect data using interviews with a group of PREGs developers, physical therapy experts, and patients. We employ the thematic analysis method to analyze the collected data. RESULTS: We found that the advantages and limitations of LM are related to (1) the role as PREG development tool that enables hand movements detection, (2) the capability to be a mobile and easy-to-use capturing technology, and (3) the contribution to add value in rehabilitation therapy by motivating physical therapists and patients to use PREGs. CONCLUSION: The analysis shows that LM is a suitable and cost-effective solution for developing usable PREGs for some hand and finger rehabilitation movements with a moderate development effort. However, the development maturity of LM poses limitations related to reliability and robustness, preventing the use of LM as a standalone physical rehabilitation tool. Our findings serve as guidelines for developers and physical therapists during the development and use of PREGs targeted at hands and fingers, guiding the decision-making process during feasibility analysis and design stages.

Results of a special interdisciplinary hand therapy program for work-related injuries.

The importance of postoperative care of hand injuries is undisputed, but sometimes more intensive therapy is needed. The objective of this study was to evaluate the benefits of a specialized hand rehabilitation program supervised by hand surgeons. The outcomes and short-term follow-up of 76 patients with upper extremity injuries were analyzed through patient self-reported parameters as well as objective functional scores. Improvement in all self-assessed parameters during rehabilitation was statistically significant for the DASH (p<0.001) as well as the EQ-5D (p<0.05). Further improvement in the short-term (14 weeks) was only seen for the DASH score (p<0.05). During rehabilitation, there was a statistically significant improvement in all objective measurements. Among patients with finger injuries, 71% were able to return to work. Our specialized hand rehabilitation program provides benefits for all patients. There are differences between types of upper extremity injuries in terms of the effects and necessary treatments.

Work-related Transitions Following Hand Injury: Occupational Therapy Scoping Review.

BACKGROUND.: Occupational therapists who facilitate work-related transitions after hand injury require robust evidence to inform practice. PURPOSE.: To identify the occupational therapist's contribution to facilitate work-related transitions for persons with hand injuries and identify gaps in existing knowledge. METHOD.: A systematic search was conducted from 2008 to 2018 to identify articles and doctoral theses published across 14 databases. Data was analysed descriptively. FINDINGS.: In total, 15 studies from 16 countries (14 high and 2 upper-middle income) were identified. Four strategies to facilitate work-related transitions were identified. Clear differences were evident across country groupings. IMPLICATIONS.: The paucity of research limits evidence-based practice, especially in low- and middle-income countries, which indicates the need for further research.

Gamification in rehabilitation of metacarpal fracture using cost-effective end-user device: A randomized controlled trial.

STUDY DESIGN: This is a two-group randomized controlled trial. INTRODUCTION: Finger stiffness after treatment for metacarpal fractures often occurs due to poor compliance to the conventional rehabilitation programs. Gamification has shown success in improving adherence to and effectiveness of various therapies. PURPOSE OF THE STUDY: The purpose of this study was to evaluate whether gamification, using cost-effective devices was comparable with conventional physiotherapy in improving hand functions and adherence to rehabilitation in metacarpal fractures. METHODS: A 2-group randomized controlled trial involving 19 patients was conducted. Participants were randomized to a control (conventional physiotherapy, n = 10) or interventional group (gamification, n = 9). The grips strength and composite finger range of motion were measured at the baseline and each follow-up together with Patient-Rated Wrist and Hand Evaluation scores and compliance. RESULTS: There were no significant differences on improvements of grip strength (means difference 24.38 vs 20.44, P = .289) and composite finger range of motion (means difference 50.50 vs 51.11, P = .886). However, the gamification group showed better results in Patient-Rated Wrist and Hand Evaluation (mean 0.44 vs 8.45, P = .038) and compliance (P < .05). No adverse events were reported. DISCUSSION: Our results suggest that gamification using a cost-effective device demonstrated similar effectiveness as conventional physiotherapy in post-metacarpal fracture rehabilitation. CONCLUSIONS: Gamification using a mobile device is an inexpensive and safe alternative to conventional physiotherapy for hand rehabilitation after metacarpal fractures. It effectively serves as a guide for future development of cost-effective technology-enhanced therapy.

Safety of Early Postoperative Range of Motion in Burn Patients With Newly Placed Hand Autografts: A Pilot Study.

Patients who suffer hand burns are at a high contracture risk, partly due to numerous cutaneous functional units, or contracture risk areas, located within the hand. Patients who undergo split-thickness skin grafting are often immobilized postoperatively for graft protection. Recent practice at our burn center includes an early range of motion (EROM) following hand grafting to limit unnecessary immobilization. The purpose of this study was to determine whether EROM is safe to perform after hand grafting and if there is any clinical benefit. This retrospective, matched case-control study of adults compared patients who received EROM to subjects who received the standard 3 to 5 days of postoperative immobilization. Patients were evaluated for graft loss and range of motion. Seventy-one patients were included in this study: 37 EROM patients and 34 matched controls. Six patients experienced minor graft loss, three of these were not attributable to EROM. All graft loss was less than 1 cm and none required additional surgery. Significantly more patients who received EROM achieved full-digital flexion by the first outpatient visit (25/27 = 92.6% vs 15/22 = 68.2%; P = .028). Performing EROM does not cause an increase in graft loss. All areas of graft loss from the EROM group healed without intervention. There appears to be a benefit to EROM since there was a significant improvement in the patients' ability to make a full fist at initial outpatient follow-up. Additional prospective analysis is needed to examine the true clinical utility of EROM in the hand and other contracture-prone areas.

Use of mobile applications in hand therapy.

INTRODUCTION: Mobile devices can be incorporated into therapy as an engaging alternative to traditional therapy options. The use of mobile devices and smartphone applications can enhance the quality of care provided by health care professionals. PURPOSE: To find mobile apps that can be incorporated into hand therapy practice. METHODS: Hand therapy evaluation, interventions, proprioception, laterality, and home exercise program applications can be incorporated into practice. Patient education can also be provided via the use of mobile applications. CONCLUSION: Smartphone applications can be a valuable intervention and impact performance in individuals with impaired hand function. Smartphone applications offer a client-centered, and potentially motivating, activity option that can be utilized to aid the hand therapist.
