摘要:

The residual limb-socket interface pressures were measured in 13 transtibial amputees who use prostheses with side joints and thigh lacers. The hypothesis of this study was that the interface pressures with a thigh lacer are lower than the pressures without a thigh lacer. Comparison of the interface pressures with and without thigh lacer-side joints revealed a significant difference (p < 0.05). The reduction in the interface pressures indicates that a thigh lacer redistributes the pressures from the residual limb onto the thigh, and a thigh lacer-side joint suspension may be indicated in some transtibial amputees.

摘要:

This article discusses the upper extremity prosthetic treatment of a 13-year-old young man with right hemiparesis and mild learning difficulties. Past prosthetic devices offered little independent function because the strength and energy required to operate the prosthesis was too overwhelming for him. With his new prosthesis, he has gained more independent function, cosmesis, and comfort. Accompanied by an upper extremity rehabilitation program, this prosthesis allows the patient increased independence and function in his daily activities at home and school. The importance of a structured program from an occupational therapist is vital to the success of this prosthesis. This is a case report where an experienced upper extremity prosthetic team successfully fit a patient who never functionally used a prosthesis until the age of 13

摘要:

Results from multiple instrumented gait analysis trials of seven traumatic transfemoral amputees capable of community ambulation are reviewed. All subjects used a novel rotary hydraulic prosthetic knee offering both stance and swing phase control, in combination with various contemporary prosthetic ankle-foot mechanisms. Unlike previous hydraulic stance and swing units, the Otto Bock 3R80 knee provides stance stability whenever the desired weightbearing load is applied to the prosthesisThe mechanical principles and basic functions of the knee joint are described. Results from three phases of gait studies are presented to identify inter-individual variability and the effect of varying sagittal plane knee alignment and the ankle-foot mechanism selected. Subjective amputee preferences for specific foot devices are presentedThe pattern of hip moments on the amputated side during stance phase are characteristic of the individual amputee. However, the magnitude and timing of the hip moments vary considerably between individual amputees. So long as the prosthetic knee remains biomechanically stable, it appears that alignment alterations or the use of varying foot devices have little impact on the hip extension moment. On the other hand, the hip flexion effort required for the amputee to initiate knee flexion in late stance phase is directly related to the linear position of the prosthetic knee in the sagittal plane: the more posterior the knee, the greater the effort needed to begin swing phaseClinical function of this hydraulic prosthetic knee was considered satisfactory with all tested ankle-foot mechanisms. Transfemoral amputee preference for specific prosthetic feet in this study seemed to be determined by two biomechanical factors: (1) their ability to benefit from the use of a dynamic response foot without compensating with the non-amputated knee, and (2) their ability to generate a hip extension moment on the prosthetic side during the weight acceptance phase of gait

摘要:

We studied 25 patients treated part-time with a Wilmington thoracolumbosacral orthosis in order to determine its efficacy. Our study focused on the outcomes of 19 patients. All were skeletally immature (Risser 0,1, or 2) at the initiation of orthotic management, with one exception. We followed them until skeletal maturity, until they became non-compliant, or until they required operative intervention. Fifteen of the 19 patients (79%) had curves that did not progress more than 5° during the time interval that the patient was compliant with wearing the orthosis part-time. The remaining four patients (21%) had at least one curve that progressed more than 5° while wearing the orthosis part-time. These results are comparable to those found in the literature for full-time bracing protocols

摘要:

Programmable centrode knee units have been developed with the primary objective of adding a centrode that could be aligned taking into consideration the patient's residual limb length, strength, and gait determinants. This design allows the prosthetist to more accurately align a prosthesis to meet the amputee's individual characteristics. This article presents the basic function and benefits of the four-bar configuration, as well as the additional mechanical function of the five-bar knee unit. The benefits to the amputee wearing programmable centrode knee unit designs are discussed
