Abstract Objective To study the effect of different wrist flexion and extension angles on the results of Hoffmann’s sign.Methods Thirty-seven patients with cervical spondylotic myelopathy and fifty objectives as control group were examinated at 15° palmar flexion, 0° neutral, 30° back extension, and 60° back extension of the wrist joint to observe Hoffmann's sign.ResultsThe patients with cervical spondylotic myelopathy did not present significantly different results of Hoffmann’s sign at 0° neutral, 30° back extension, and 60° back extension, but significantly different at 15° palmar flexion (P<0.05). In control group, there is no significant difference at 15° palmar flexion, 0° neutral, 30° back extension, but significantly different at 60° back extension (p<0.05).ConclusionThe different angles of wrist flexion and extension present a significant impact on the results of Hoffmann’s sign examination. For the patients with cervical spondylotic myelopathy, it is reliable to test Hoffmann’s sign at 30° wrist back extension.

Joint angle kinematics of the throwing limb from the early-cocking phase to ball release were investigated for the fastball (FB) and curveball (CB) baseball pitches through use of a three-dimensional film analysis technique. Small sticks were fixed to the hand and forearm to permit rotations of the radioulnar and wrist joint to be calculated. The actions were very similar for two pitches within one subject. There were no differences in the motions of the shoulder and elbow joints or in the temporal sequences between FB and CB pitches. However, there was a significant difference (p<0.05) in the motion of supination/pronation of the forearm and dorsiflexion/palmar flexion of the wrist prior to the ball release; the forearm was supinated more in the CB (maximum supination: 39.9 ±6.0° at 0.072 ±0.045 s before ball release, or BRL) compared to the FB (19.4 ±8.5° at 0.076 ±0.046 s before BRL), whereas the wrist was dorsiflexed more in the FB (maximum dorsiflexion: 41.7 ±6.5° at 0.039 ±0.011 s before BRL) compared to the CB (31.2 ±4.7° at 0.036 ±0.013 s before BRL) during late-cocking and acceleration phases leading to the ball release.

Many authors have studied physical and functional changes in individuals post-stroke, but there are few studies that assess changes in the non-plegic side of hemiplegic subjects. This study aimed to compare the electromyographic activity in the forearm muscles of spastic patients and clinically healthy individuals, to determine if there is difference between the non-plegic side of hemiplegics and the dominant member of normal individuals. 22 hemiplegic subjects and 15 clinically healthy subjects were submitted to electromyography of the flexor and extensor carpi ulnaris muscles during wrist flexion and extension. The flexor muscles activation of stroke group (average 464.6 u.n) was significantly higher than the same muscles in control group (mean: 106.3 u.n.) during the wrist flexion, what shows that the non affected side does not present activation in the standart of normality found in the control group.

Objective: To compare the therapeutic effects of acupotomy trinity lysis and traditional acupotomy on cervical spondylotic myelopathy. Methods: A total of 205 patients with cervical spondylotic myelopathy of liver and kidney deficiency syndrome were randomly divided into the experimental group (105 cases) and the control group (100 cases). The experimental group was relaxed with acupotomy in three positions: Heaven (tian), Human (ren) and Earth (di). Traditional acupotomy was used to relax Ashi acupoints of the affected vertebra in the control group. One treatment was conducted in one week, and the duration of one course of treatment was three weeks. The VAS, JOA score and NDI index were observed after treatment.  Results: Before and after treatment, the total treatment efficiency of the treatment group was 95.23%, and that of the control group was 80.00%, there was significant difference between the two groups, P<0.05; Before operation, there was no significant difference in JOA score, NDI index score, and VAS score between the treatment group and the control group (P>0.05); there was no significant difference after 1 week (P>0.05), but there were significant differences between the two groups 2 weeks and 3 weeks after operation (P<0.05). Conclusion: Acupotomy trinity lysis is a safe, effective and economical treatment for cervical spondylotic myelopathy.

Parkinsonian rigidity has been thought to be constant through a full range of joint angle. The aim of this study was to perform a detailed investigation of joint angle dependency of rigidity. We first measured muscle tone at the elbow joint in 20 healthy subjects and demonstrated that an angle of approximately 60° of flexion marks the division of two different angle-torque characteristics. Then, we measured muscle tone at the elbow joint in 24 Parkinson’s Disease (PD) patients and calculated elastic coefficients in flexion and extension in the ranges of 10°–60° (distal) and 60°–110° (proximal). Rigidity as represented by the elastic coefficient in the distal phase of elbow joint extension was best correlated with the UPDRS rigidity score (r=0.77). A significant difference between the UPDRS rigidity score 0 group and 1 group was observed in the elastic coefficient in the distal phase of extension (P<0.0001), whereas no significant difference was observed in the proximal phase of extension and in each phase of flexion. Parkinsonian rigidity shows variable properties depending on the elbow joint angle, and it is clearly detected at the distal phase of elbow extension.

Abstract Purpose: Approximately 30% of patients with hereditary multiple osteochondromas (HMO) have forearm deformity and dysfunction. The aim of this retrospective study was to review our experience with the surgical treatment of children with HMO and Masada IIb forearm deformities.Methods: Data of eight children treated for HMO Masada IIb forearm deformity at our hospital between 2015 and 2019 were collected from the hospital records and retrospectively reviewed. All patients underwent ulnar lengthening by distraction osteogenesis using either the Orthofix or Ilizarov external fixator. Range of movements at the elbow and wrist joints, and forearm supination/pronation, before and after the operation were recorded. Radiographs were evaluated by the Fogel method, and wrist joint function by the Krimmer method.Results: Follow-up radiographs showed significant improvement in relative ulnar shortening after treatment (pre-operative 9.23 ± 5.21 mm; post-operative 0.33 ± 4.13 mm). Changes in radial articular angle (pre-operative 33.55° ± 3.88° to 32.78° ± 6.57°) and carpal slip (pre-operative 45.00% ± 19.09%; post-operative 43.13% ± 16.68%) were not significant. Elbow flexion and extension, wrist flexion and extension, ulnar and radial deviation at wrist, and forearm rotation were significantly improved after surgery. Wrist function was graded as excellent in seven patients and as good in one patient. One patient treated with the Ilizarov external fixator had poor radial head reduction.Conclusion: Ulnar lengthening with distraction osteogenesis is an effective treatment for HMO Masada IIb deformities. The optimum site for ulnar osteotomy appears to be at the proximal one-third to one-fourth of the ulna.

Background and Objectives: Patients with hand injuries and other conditions presenting to ER or office are usually given local anaesthesia to evaluate the case or perform a certain procedure. Lignocaine in various concentrations with or without adrenaline is used. Lignocaine with adrenaline is shown to be more acidic than plain lignocaine of similar concentration causing more pain. Sodium bicarbonate has been shown to decrease the pH of lignocaine hence decrease the pain related to injection. So this study is carried out to compare buffered (sodium bicarbonate) and plain lignocaine with adrenaline for pain control and analgesia for patients undergoing hand surgery. Material and methods: Patients in the age group of 18-60 years were divided into two groups- a control group (receiving lignocaine hydrochloride with adrenaline) and a study group (receiving carbonated lignocaine with adrenaline) and were evaluated for pain at the site of injection, onset of action of the anesthetic and its duration of analgesia and anaesthesia. Results: A total of 38 patients were included, 19 in each group. There was a significant difference in the pain score at time of injection between study group and control group (median,range: 2( 1-5) and 7(4-9) respectively ) with p<0.001. However, there was no significant difference in terms of onset of action, duration of anaesthesia and return of pain sensation. One patient developed swelling over wrist joint who received buffered solution. Conclusion: Local anesthetics used routinely in hand department should be buffered with sodium bicarbonate to reduce pain on injection of drugs in the patients.

The second version of The Armed Robotic Control for Training in Civilian Law Enforcement, or ARCTiC LawE is presented in this paper. The ARCTiC LawE is an upper body exoskeleton designed to assist in training civilians, military, and law enforcement personnel. This second iteration tests the effect of locking out wrist flexion and extension for handgun training in addition to locking out the radial and ulnar deviation from the first version of The ARCTiC LawE. The experimental group scored significantly higher than the control group at 21 feet and 45 feet over a two-week period. The training occurred in week one and testing occurred in week two. This study lays the groundwork for continued research on transfer of training effectiveness with the ARCTiC LawE.

Abstract Introduction: In the majority of cases, anterior cruciate ligament (ACL) injuries require specialist surgical and physiotherapeutic treatment. The fact that the patient regains a full range of flexion and extension in the knee joint as well as the reduction or elimination of pain is a significant determinant of successful physiotherapy. Material and methods: The study included 72 randomly selected individuals with a complete ACL tear who were qualified for its surgical reconstruction. The research group included 37 patients aged 18-60 (mean age 37±10.3 years). All the participants from this group underwent physiotherapy based on recognised schemes of rehabilitation and performed for 4 weeks before the reconstruction surgery. The control group included 35 patients aged 18-60 (mean age 34±10.0 years) who did not undergo any presurgical physiotherapy programme. Results: Both in the research group and in the control group, subsequent measurements revealed a statistically significant improvement in the range of flexion and extension (p<0.05). Statistical analysis revealed a significantly better extension 1 week and 6 weeks after the ACL reconstruction (p<0.05) in the research group. Statistically significant differences in the level of pain in patients from both groups were noted in subsequent measurements (p<0.05). Also, a statistically significant difference concerning pain assessment 12 weeks after the reconstruction was noted in the research group (p<0.05). Conclusions: A quicker recovery of the range of extension in the operated knee joint and lower intensity of pain in the final measurement noted in the research group may indicate a certain therapeutic value of presurgical physiotherapy.

Objective:To assess whether mental imagery of gripping prevents the loss of grip strength associated with forearm immobilization.Design:Pretest–posttest randomized-group design.Setting:Laboratory.Participants:13 female and 5 male university students, age between 17 and 30 years, randomly assigned into 2 groups—1 control and 1 experimental.Interventions:Both groups had their nondominant forearms immobilized for 10 days. The experimental group undertook three 5-min mental-imagery sessions daily, during which they imagined they were squeezing a rubber ball.Main Outcome Measures:Wrist-flexion and -extension and grip strength before and after immobilization.Results:There was no significant change in wrist-flexion or -extension strength in the mental-imagery group. The control group experienced a significant decrease in wrist-flexion and -extension strength during the period of immobilization (P< .05).Conclusions:Despite study limitations, the results suggest that mental imagery might be useful in preventing the strength loss associated with short-term muscle immobilization

ABSTRACT Objective: To evaluate morphometric variations of the cervical spine in patients with cervical spondylotic myelopathy (CSM) using dynamic magnetic resonance imaging (MRI) in neutral, flexion and extension positions. Methods: This is a prospective study of patients with CSM secondary to degenerative disease of the cervical spine. The morphometric parameters were evaluated using T2-weighted MRI sequences in the sagittal plane in neutral, flexion and extension position of the neck. The parameters studied were the anterior length of the spinal cord (ALSC), the posterior length of the spinal cord (PLSC), the diameter of the vertebral canal (DVC) and the diameter of the spinal cord (DSC). Results: The ALSC and PLSC were longer in flexion than in extension and neutral position, with statistically significant difference between the flexion and extension position. The DVC and the DSC were greater in flexion than in extension and neutral position, however, there was no statistically significant difference when they were compared in the neutral, flexion and extension positions. Conclusion: Dynamic MRI allows to evaluate morphometric variations in the cervical spinal canal in patients with cervical spondylotic myelopathy.
