Rehabilitation of the arthrofibrotic knee.
This paper describes the postoperative rehabilitation of the arthrofibrotic knee, with specific emphasis on modern rehabilitation techniques. The significance of prevention and early recognition is discussed. The importance of early motion and patellar mobility is emphasized and specific exercises to prevent and treat stiffness are described. Continuous passive motion, bracing, and exercise--on the stationary bicycle, on the treadmill, and in water--are adjuncts in the program. Strengthening is added when motion is re-established and there is no swelling or pain. Sport-specific activities are added if progress is satisfactory and motion is maintained. If pain, swelling, or stiffness develops, exercises should be discontinued. Modalities such as cryotherapy, ultrasound, electrical stimulation, rest, and manipulation can be used judiciously. Anti-inflammatory and analgesic medications should be used to prevent inflammation, to control pain, and to allow more aggressive rehabilitative exercises.

Repeated passive stretching: acute effect on the passive muscle moment and extensibility of short hamstrings.
OBJECTIVE: To examine the response of short hamstring muscles to repeated passive stretching. DESIGN: A repeated measures design. SETTING: A university laboratory for human movement analysis in a department of rehabilitation. SUBJECTS: Students (7 men, 10 women) from the Department of Human Movement Sciences. MAIN OUTCOME MEASURES: The lift force, range of motion, pelvic-femoral angle, first sensation of pain, and electromyogram of the hamstrings were measured. RESULTS: Comparison of the data of the test group (n = 17) after five successive passive stretch tests by means of an instrumental straight-leg raising test showed no significant change of the variables passive muscle stiffness and extensibility (p>.05). CONCLUSION: The acute effect of repeated passive stretching of short hamstring muscles is negligible. With an instrumental straight-leg raising test, the relevant muscle variables can be examined noninvasively.

Robot-assisted movement training compared with conventional therapy techniques for the rehabilitation of upper-limb motor function after stroke.
OBJECTIVE: To compare the effects of robot-assisted movement training with conventional techniques for the rehabilitation of upper-limb motor function after stroke. DESIGN: Randomized controlled trial, 6-month follow-up. SETTING: A Department of Veterans Affairs rehabilitation research and development center. PARTICIPANTS: Consecutive sample of 27 subjects with chronic hemiparesis (>6mo after cerebrovascular accident) randomly allocated to group. INTERVENTIONS: All subjects received twenty-four 1-hour sessions over 2 months. Subjects in the robot group practiced shoulder and elbow movements while assisted by a robot manipulator. Subjects in the control group received neurodevelopmental therapy (targeting proximal upper limb function) and 5 minutes of exposure to the robot in each session. MAIN OUTCOME MEASURES: Fugl-Meyer assessment of motor impairment, FIMtrade mark instrument, and biomechanic measures of strength and reaching kinematics. Clinical evaluations were performed by a therapist blinded to group assignments. RESULTS: Compared with the control group, the robot group had larger improvements in the proximal movement portion of the Fugl-Meyer test after 1 month of treatment (P<.05) and also after 2 months of treatment (P<.05). The robot group had larger gains in strength (P<.02) and larger increases in reach extent (P<.01) after 2 months of treatment. At the 6-month follow-up, the groups no longer differed in terms of the Fugl-Meyer test (P>.30); however, the robot group had larger improvements in the FIM (P<.04). CONCLUSIONS: Compared with conventional treatment, robot-assisted movements had advantages in terms of clinical and biomechanical measures. Further research into the use of robotic manipulation for motor rehabilitation is justified.

Treatment of a knee contracture using a knee orthosis incorporating stress-relaxation techniques.
The subject of this case report was a 67-year-old Caucasian woman who had undergone total knee arthroplasty of the right knee. Postoperative physical therapy and a new orthosis that utilizes principles of stress relaxation (constant displacement) and static progressive stretching were used to reestablish range of motion. The total treatment time (cumulative orthosis wear time) was 32.5 hours over a period of 29 days, and the patient obtained a 17-degree increase in active range of motion. Six months later there was no measurable loss in range of motion. The results of the treatment may be beneficial for some patients. Researchers and clinicians need to conduct studies to further evaluate this approach to knee contracture management.

Comparison of two techniques of robot-aided upper limb exercise training after stroke.
OBJECTIVE: This study examined whether incorporating progressive resistive training into robot-aided exercise training provides incremental benefits over active-assisted robot-aided exercise for the upper limb after stroke. DESIGN: A total of 47 individuals at least 1 yr poststroke were enrolled in this 6-wk training protocol. Paretic upper limb motor abilities were evaluated using clinical measures and a robot-based assessment to determine eligibility for robot-aided progressive resistive training at study entry. Subjects capable of participating in resistance training were randomized to receive either active-assisted robot-aided exercises or robot-aided progressive resistance training. Subjects who were incapable of participating in resistance training underwent active-assisted robotic therapy and were again screened for eligibility after 3 wks of robotic therapy. Those subjects capable of participating in resistance training at 3 wks were then randomized to receive either robot-aided resistance training or to continue with robot-aided active-assisted training. RESULTS: One subject withdrew due to unrelated medical issues, and data for the remaining 46 subjects were analyzed. Subjects in all groups showed improvement in measures of motor control (mean increase in Fugl-Meyer of 3.3; 95% confidence interval, 2.2-4.4) and maximal force (mean increase in maximal force of 3.5 N, P = 0.027) over the course of robot-aided exercise training. No differences in outcome measures were observed between the resistance training groups and the matched active-assisted training groups. Subjects' ability to perform the robotic task at the time of group assignment predicted the magnitude of the gain in motor control. CONCLUSION: The incorporation of robot-aided progressive resistance exercises into a program of robot-aided exercise did not favorably or negatively affect the gains in motor control or strength associated with this training, though interpretation of these results is limited by sample size. Individuals with better motor control at baseline experienced greater increases in motor control with robotic training.

[Arthrolysis of the elbow in posttraumatic contracture].
Intra- and periarticular fractures about the elbow joint are treated with open reduction and internal fixation. This allows early functional after-treatment. Nevertheless, the range of motion remains more or less unsatisfactory. In these cases open arthrolysis provides a considerable improvement in joint function. We therefore recommend this operation when the hardware is removed about 9 months after the accident. The reasons for post-traumatic contracture of the elbow could be intrinsic such as interposed fragments, intra-articular adhesions, incongruity of the articular surfaces--or extrinsic--like contractures of the capsule and ligaments, adhesions of different layers, ectopic bone formations. In most cases a combination of both can be found. Important conditions for successful arthrolysis are mostly intact joint surfaces, failure of all conservative efforts to improve the arc of motion, a motivated patient who understands clearly the risks and benefits that could reasonably be expected by the operative procedure and rehabilitation and, last but not least, a skilled, experienced surgeon. The choice of the approach depends on the main location of the post-traumatic changes and on previous incisions. Osteotomy of the radial epicondyle gives a much better view of the joint and should be performed whenever necessary. The exact course of the operation may not be standardized. The main point is to remove scarred adhesions and bony irregularities. An individually modified rehabilitation program is as important as the operative procedure itself to achieve the best results possible. In general, the exercises should not cause pain. In the first few days plaster casts in flexion and extension are used. Physiotherapy is supported by CPM machines as early as possible. Patients must be prepared with the help of drugs and the application of ice bags. Even after months improvement of motion can be obtained. In a retrospective follow-up study, 125 out of 168 patients with arthrolysis of the elbow joint were reviewed. Most patients sustained a fracture of the distal humerus. In 77%, the results were graded as very good, good or satisfactory, i.e., the average relative improvement amounted to at least 40% according to the criteria of W. Blauth. Patients with very severe (preoperative ROM 0-30 degrees) and severe (preoperative ROM 30-60 degrees) contractures profited more (relative improvement 60%) than the others (relative improvement 45%). Overall, the average arc of total motion increased 49 degrees; the relative improvement of motion increased by 58%.

The use of continuous passive motion after arthroscopically assisted anterior cruciate ligament reconstruction: help or hindrance?
One hundred and eight patients having undergone arthroscopic anterior cruciate replacement and having had continuous passive motion (CPM) as part of their immediate post-operative regime were prospectively compared with 108 patients having an identical operative procedure but not receiving CPM. All patients were operated on by the same surgeon, and the two groups were well matched for age, weight and associated injuries and procedures. Those not receiving CPM required significantly less analgesia (P = 0.0001), had less blood loss measured in the drains (P = 0.001) and had a shorter hospital stay (P = 0.0001). At review 6 months after surgery, there was no significant difference between the two groups in the range of movement of the operated leg compared to the normal leg.

Application of passive stretch and its implications for muscle fibers.
To increase range of motion, physical therapists frequently use passive stretch as a means of gaining increased excursion around a joint. In addition to clinical studies showing effectiveness, thereby supporting evidence-based practice, the basic sciences can provide an explanation how a technique might work once a technique is known to be effective. The goal of this article is to review the potential cellular events that may occur when muscle fibers are stretched passively. A biomechanical example of passive stretch applied to the ankle is used to provide a means to discuss passive stretch at the cellular and molecular levels. The implications of passive stretch on muscle fibers and the related connective tissue are discussed with respect to tissue biomechanics. Emphasis is placed on structures that are potentially involved in the sensing and signal transduction of stretch, and the mechanisms that may result in myofibrillogenesis are explored.

Continuous passive motion following total knee arthroplasty.
BACKGROUND: Knee arthroplasty (KA) is a common intervention that can enhance the quality of life for patients with osteoarthritis (OA) and rheumatoid arthritis (RA). Post-surgery rehabilitation protocols often include continuous passive motion (CPM). However, CPM protocols vary considerably amongst institutions. OBJECTIVES: The purpose of the current meta-analysis is to evaluate the effectiveness of continuous passive motion following total knee arthroplasty. SEARCH STRATEGY: An electronic search of MEDLINE (1966 to 2002), EMBASE (1988 to 2002), CINAHL (1982 to 2002), HEALTH STAR (1991 to 1994) and CURRENT CONTENTS (1997 to 2002) was conducted to identify randomized controlled trials. SELECTION CRITERIA: Following an a priori protocol, only randomized controlled trials of CPM for the treatment of participants post KA were eligible. Subjects were 18 years of age or older and had a pre-surgery diagnosis of degenerative joint disease. Both the experimental and control groups received physiotherapy. In addition to the physiotherapy intervention, the experimental group received CPM. DATA COLLECTION AND ANALYSIS: Two reviewers independently selected trials for inclusion. Data were then extracted and the quality of the trial assessed using predetermined forms. Outcome measures of interest were: active and passive knee range of motion (ROM) length of hospital stay, pain, swelling and quadriceps strength. A fixed effects model was used throughout for continuous variables, except where heterogeneity existed; in which case, a random effects model was used. Results were analyzed as weighted mean differences (WMD) with 95% confidence intervals (CI). Standardized mean differences (SMD) were used when different scales were used to measure the same concept (e.g. pain). Dichotomous outcomes were presented as a relative risk. MAIN RESULTS: Fourteen trials were retained for analysis. Results favouring CPM were found for the main comparison of CPM combined with physiotherapy (PT) versus PT alone at end of treatment. For the primary outcomes of interest, CPM combined with PT was found to statistically significantly increase active knee flexion (WMD 4.30 degrees, 95% CI: 1.96, 6.63) and decrease length of stay (WMD -0.69 days, 95% CI: -1.35, -0.03). CPM was also found to decrease the need for post-operative manipulation (RR 0.12, 95% CI: 0.03, 0.53). CPM did not significantly improve passive knee flexion and passive or active knee extension. REVIEWER'S CONCLUSIONS: CPM combined with PT, may offer beneficial results compared to PT alone in the short term rehabilitation following total knee arthroplasty.

The influence of continuous passive motion on the results of total knee arthroplasty.
Twenty-two primary total knee arthroplasties were prospectively randomized into one of two treatment protocols. Ten of these patients were managed in the hospital after surgery by means of a postoperative splint. The remaining 12 patients were placed immediately postoperatively in the recovery room into the continuous passive motion (CPM) device. The study compares the range of motion, analgesic use, hospital stay, and the volume of hemovac output in the two groups. These cases demonstrated two statistically significant findings with the use of CPM: (1) decreased use of narcotic analgesics and (2) decreased length of hospital stay.

Gap formation after flexor tendon repair in zone II. Results with a new controlled motion programme.
Intratendinous metal markers were used to study gap formation in 36 flexor digitorum profundus repairs during and after early controlled motion with a programme combining dynamic traction and passive flexion to all four digits. The mean gap 3 weeks after operation was 2.5 mm. The mean final gap was 2.6 mm. The results of linear regression analysis showed that gap formation within the observed range from 0 to 8.5 mm did not negatively affect tendon excursions or clinical results in terms of active interphalangeal joint range of motion. These findings are in accordance with the results of a previous study of gap formation in patients treated with a modified traditional Kleinert traction programme. Together the two studies confirm that controlled motion is effective in restricting the adhesions associated with gap formation during postoperative immobilisation.

The early treatment of motion complications after reconstruction of the anterior cruciate ligament.
The use of active and passive knee motion in the immediate postoperative period and a treatment plan for early postoperative limitations in knee motion has proven highly effective in restoring motion after anterior cruciate ligament (ACL) reconstruction. Of 207 knees, 189 (91%) regained a full range of motion of 0 degrees-135 degrees. The remaining 18 knees (9%) did not regain motion as rapidly as the others and were placed in an early postoperative phased treatment program. Six knees had serial extension casts, nine had early gentle manipulation under anesthesia, and three had arthroscopic lysis of intraarticular adhesions and scar tissue. Fourteen of these 18 knees regained a full range of knee motion. Two of the remaining four knees lacked 5 degrees of full extension, whereas the other two, in patients who had failed to follow medical advice and the rehabilitation program, had permanent and significant limitation of motion. The incidence of postoperative motion problems was related to the extent of the surgical procedure. The incidence was 4% in patients who had only ACL reconstruction, 10% in cases in which added lateral extraarticular procedure had been done, 12% where a meniscus repair had been done, and 23% where a medial collateral ligament repair was done.

Effects of therapeutic passive exercise of hip and knee joints on the soleus H-reflex.
UNLABELLED: The effect of passive movement of a leg on alpha-motoneurons of the soleus was investigated while the ankle was immobilized. Electrophysiological parameters of the H-reflex were used. Nineteen fully informed volunteers with no history of neurological or internal disease participated in the study. The mean age across all the experiments was 20.9 years. Contributions to the modulation of the soleus H-reflex by hip and knee joint movements were analyzed in two tasks. These were the most general movement methods used in physical therapy. Soleus H-reflexes were measured six times per experiment. Stimulation intensity was set at the 1.1 x M-wave threshold. RESULTS: 1. In both exercises, H/M decreased as flexion progressed with fast or slow movement. The quadriceps femoris inhibited soleus muscle alpha-motoneurons in both experiments. 2. H/M increased on initiation of extension in the two-joint exercise. In the single-joint exercise, inhibition was retained through the extension phase during both fast and slow movements. Hamstring effects were strong during extension of the leg. 3. In both exercises, the H/M for fast movement was lower than for slow movement at all angles, indicative that H/M decreases with fast movement irrespective of the effects produced by the hip joint.

The effects of multiple-strand suture methods on the strength and excursion of repaired intrasynovial flexor tendons: a biomechanical study in dogs.
This study was designed to determine the effects of in vivo multistrand, multigrasp suture techniques on the strength and gliding of repaired intrasynovial tendons when controlled passive motion rehabilitation was used. Twenty-four adult mongrel dogs were divided into 4 groups and their medial and lateral forepaw flexor tendons were transsected and sutured by either the Savage, the Tajima, the Kessler, or the recently developed 8-strand suture method. The tendon excursion, joint rotation, and tensile properties of the repaired tendons were evaluated biomechanically at 3 and 6 weeks after surgery. It was found that neither time nor suture method significantly effected proximal and distal interphalangeal joint rotation or tendon excursion when the 4 techniques were compared to each other. Normalized load value (experimental/control) was significantly affected by both the suture method and the amount of time after surgery, however. The Savage and 8-strand repair methods had significantly greater strength than did the Tajima method at each time interval (p < .05 for each comparison). In addition, the 8-strand method had significantly greater normalized load values than did the Savage method at each time interval (p < .05 for each comparison). Normalized stiffness (experimental/control) for the 8-strand repair method was significantly greater than that for the Tajima and Savage methods at 3 and 6 weeks after surgery (p < .05). In addition, the normalized stiffness values for the 6-week groups was significantly greater than those for the 3-week groups (p < .05). It was concluded that the method of tendon suture was a significant variable insofar as the regaining of tendon strength was concerned and that the newer low-profile 8-strand repair method significantly expands the safety zone for the application of increased in vivo load during the early stages of rehabilitation.
