Training Protocols

A novel ankle-foot prosthesis with adjustable range-of-motion limits was developed to support implementation of gradual training protocols in the physical therapy of new amputees. Stakeholder interviews drove design requirements that guided the development. Our first prototype did not pass structural strength testing, but with minor revisions to some components, our second prototype was able to pass structural strength testing to the P6 load level (125kg user) of the ISO 10328 standard for prosthetic feet. The system is ready for laboratory testing with prosthesis users and clinicians to generate further insight for future design iterations.

AbstractThis study was performed to evaluate the effects of Mirror therapy combined with EMG-triggered Functional Electrical Stimulation on upper extremity function in patient with Chronic Stroke. A total of 24 chronic stroke patients were divided into 3 groups. Group I (n=8) was given with traditional physical therapy (TPT), group II (n=7) was given with traditional physical therapy and mirror therapy (MT), and group III (n=9) was given with traditional physical therapy and mirror therapy in conjunction with EMG-triggered Functional Electrical Stimulation (EMGFES-MT). Each group performed one hour a day 5 times a week for 6 weeks.We obtained the following result between before and after treatments about changes of elbow flexion muscle strength (EFMS), elbow extension muscle strength (EEMS), wrist flexion muscle strength (WFMS), wrist extension muscle strength (WEMS), elbow flexion range of motion (EFROM), elbow extension range of motion (EEROM), wrist flexion range of motion (WFROM), wrist extension range of motion (WEROM), grip strength (GS) and upper extremity function.Each group showed a significant difference in EFMS, EEMS, WFMS, WEMS, EFROM, EEROM, WFROM, WEROM, GS and upper extremity function (p<0.05) EMFES-MT group revealed significant differences in EEMS, WEROM, grip strength and upper extremity function as compared to the other groups (p<0.05). No difference was found in the change of spasticity among the 3 groups.Our results showed that EMFES-MT was more effective on elbow, WFMS, WEMS, AROM, grip strength and upper extremity function in patients with chronic stroke. We suggest that this study will be able to be used as an intervention data for recovering upper extremity function in chronic stroke patients

Degree Equation

The first metatarsal and medial cuneiform form an important functional unit in the foot, called “first ray”. The first ray normal range of motion (ROM) is difficult to quantify due to the number of joints that are involved. Several methods have previously been proposed. Controversy exists related to normal movement of the first ray frontal plane accompanying that in the sagittal plane. The objective of this study was to investigate the ROM of the first ray in the sagittal and frontal planes in normal feet. Anterior-posterior radiographs were done of the feet of 40 healthy participants with the first ray in a neutral position, maximally dorsiflexed and maximally plantarflexed. They were digitalized and the distance between the tibial malleolus and the intersesamoid crest in the three positions mentioned was measured. The rotation of the first ray in these three positions was measured. A polynomic function that fits a curve describing the movement observed in the first ray was obtained using the least squares method. ROM of the first ray in the sagittal plane was 6.47 (SD 2.59) mm of dorsiflexion and 6.12 (SD 2.55) mm of plantarflexion. ROM in the frontal plane was 2.69 (SD 4.03) degrees of inversion during the dorsiflexion and 2.97 (SD 2.72) degrees during the plantarflexion. A second-degree equation was obtained, which represents the movement of the first ray. Passive dorsiflexion and plantarflexion of the first ray were accompanied by movements in the frontal plane: 0.45 degrees of movement were produced in the frontal plane for each millimeter of displacement in the sagittal plane. These findings might be useful for the future design of instruments for clinically quantifying first ray mobility.

System Characteristics

Paper reports research on dynamic system characteristics of snow skis. Laboratory and field measurements of frequency response, running surface pressure excitation, and static system characteristics are intended to provide a data base of physical information to guide future design and research. Laboratory testing procedures used give meaningful information for “straight running” but not for “turning.” In general, the turning and straight running maneuvers must be examined independently. This paper summarizes the general research observations with a minimum of detail included.

Hand Burns

We studied the efficacy of the glove-gauze regimen in treating superficial, partial-thickness and small full-thickness hand burns. Outcome measures included healing time, need for surgical intervention, need for formal physical therapy, restoration of range of motion, return to function and incidence of infection. All patients ( n = 123) successfully completed the regimen with an average healing time of 3.7 weeks. None required surgical debridement and seven (6%) required formal physical therapy. One hundred and eighteen patients (96%) regained full range of motion and 122 (99%) returned to their previous level of work. We believe that the glove-gauze regimen provides a simplified and effective means of managing hand burns. We conclude from our patients that the glove-gauze regimen is an effective treatment that can ensure uneventful healing of superficial, partial-thickness and small full-thickness burns. A majority of our patients healed with full range of motion and function without formal physical therapy. Level of evidence: IV

ObjectiveTo determine if anterior cruciate ligament (ACL) reconstruction with a quadriceps tendon (QT) could achieve faster postoperative recovery compared with hamstring tendon (HT) ACL reconstruction.MethodsThirty-seven QT patients were matched for gender, age and preinjury activity level with 74 HT patients. A 6-month postoperative assessment included standardised reported outcome measures: patient-reported outcome measures (PROMs) (International Knee Documentation Committee-subjective knee evaluation form, Knee injury and Osteoarthritis Outcome Score-knee related quality of life subscale, ACL-Return to Sport after Injury scale, Marx activity scale, anterior knee pain), range of motion (active, standing and passive), anterior knee laxity testing, hop tests (single and triple crossover hop for distance) and isokinetic strength testing of the knee extensors and flexors. T-tests or Mann Whitney U tests were used to compare data between groups.ResultsThere were no significant differences between the two groups for any of the PROMs. The HT group had reduced active and standing knee flexion range compared with the QT group (p<0.001). Isokinetic strength testing showed significant deficits in limb symmetry indices for both concentric hamstring peak torque at 60°/s (p<0.001) and 180°/s (p=0.01) in the HT group. There were significantly greater deficits in limb symmetry indices for concentric quadriceps peak torque at 60°/s (p<0.001) and 180°/s (p=0.001) in the QT group.ConclusionThe QT graft does not appear to offer a more rapid recovery in terms of knee symptoms or function which could have allowed for faster progression to the dynamic phases of rehabilitation.Level of evidenceLevel III.

Rehabilitation Time

Thirty-nine patients suffering from hallux valgus deformity were randomized into one of two treatment groups following a corrective Austin procedure. One group received physical therapy only (n = 18), and the other group received physical therapy and continuous passive motion (n = 21). Continuous passive motion was initiated immediately after surgery and patients were instructed to use continuous passive motion for 8 hr a day for 24 days. On the 7th, 14th, 21st, 28th, 60th, and 90th days, range of motion, return to conventional shoes, use of oral analgesics, and complication rate were measured. The group using continuous passive motion had greater range of motion at each postoperative visit compared with the group who used physical therapy only (P &lt; 0.05). The group who used physical therapy only took longer to return to conventional shoes and to cease oral medication than the group who used continuous passive motion (P &lt; 0.01). The use of continuous passive motion as an adjunct to physical therapy following an Austin procedure expedites the rehabilitation time and increases the rate of return to functional range of motion.
