It is well known that visual cues can improve the motor performance of Parkinsonian patients. Previous laboratory studies have examined the effects of visual cueing to the floor. This case study examined the effects of using a visual cue above eye level on the gait of a Parkinsonian man. It was found that cueing the patient to a target above eye level while waking not only improved the kinematic parameters of the gait cycle but also facilitated a more functional gait pattern with re-intergration of arm swing, rhythm, heel strike and a more erect posture. Visual targeting above eye level may serve as an important clinical tool for physiotherapists treating Parkinsonian patients.

The purpose of this study is to examine the acoustic characteristics of Parkinsonian speech, with respect to different utterance conditions, by employing acoustic/auditory-perceptual analysis. The subjects of the study were 15 patients (M=7, F=8) with Parkinson's disease who were asked to read out sentences under different utterance conditions (clear/casual). The sentences read out by each subject were recorded, and the recorded speech was subjected to cepstrum and spectrum analysis using Analysis of Dysphonia in Speech and Voice (ADSV). Additionally, auditory-perceptual evaluation of the recorded speech was conducted with respect to breathiness and loudness. Results indicate that in the case of clear speech, there was a statistically significant increase in the cepstral peak prominence (CPP), and a decrease in the L/H ratio SD (ratio of low to high frequency spectral energy SD) and CPP F0 SD values. In the auditory-perceptual evaluation, a decrease in breathiness and an increase in loudness were noted. Furthermore, CPP was found to be highly correlated to breathiness and loudness. This provides objective evidence of the immediate usefulness of clear speech intervention in improving the voice quality of Parkinsonian speech.

A 52-year-old female diagnosed with Atypical Parkinsonian Disorders (APD) about one year ago suffered from dizziness and gait disturbance. The patient was identified as Taeeumin esophagus-cold lung-dry symptomatology pattern and was treated with Jowisengcheong-tang. The patient's symptoms of dizziness and night sweats were assessed using Global Assessment Scale (GAS). And, the Unified Multiple System Atrophy Rating Scale (UMSARS) and the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) were used to assess the overall function of the patient. The patient's symptoms of dizziness and night sweats were significantly improved, and UMSARS and MDS-UPDRS scores were decreased. This case showed that Sasang constitutional medicine treatment can improve APD symptoms and improve the quality of life of the patient.

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has been found to be effective treatment of Parkinson's disease (PD). This study aims to evaluate the effect of DBS for rigidity during DBS surgery. Six Parkinsonian patients who received STN-DBS surgery participated in this study. The examiner imposed flexion and extension of a patient's wrist randomly. Resistance to passive movement was quantified by viscoelastic properties (two damping constants for each of flexion and extension phase and one spring constant throughout both phases). All Viscoelastic constants decreased by DBS (p<0.01). Specifically, reduction in damping constant during flexion ($B_f$) was greater than those of damping constant during extension ($B_e$) and of spring constant (p<0.05). $B_f$ would be appropriate for evaluation of effect of DBS for rigidity during DBS surgery.

Objectives : For Parkinsonian patients who had not reacted favorably on drug therapy are good candidate for ventroposterolateral pallidotomy, although not curative. We studied these patients after unilateral pallidotomy, to confirm the effectiveness and safety of this procedure. Methods : We evaluated the 17 patients with idiopathic Parkinson's diesease who had undergone unilateral posteroventral pallidotomy. All patients responded to levodopa initially. Mean age was 55 years(38-75years), and mean duration of disease was 9.8 years(3-20years). Pre-and postoperative evaluation at 3 month intervals included Unified Parkinson's Disease Rating scale(UPDRS) scoring, Hoehn and Yahr(H & Y) staging, and neuropsychological examinations. Results : Pallidotomy significantly improved parkinsonian symptom(tremor, rigidity, bradykinesia, dyskinesia, sensory symptom). Nine of 10 patients who showed dyskinesia preoperatively significant improvement. The mean dose of levodopa in 9 patients was lowered. The mean H & Y score and UPDRS score were improved in on and/or off time in 15 patients. Among patients who were not improved, one patient worsened, and the others showed no change. The mean overall UPDRS off score changed from 76 preoperatively to 44(33%) at 6 months and from 70 to 52(25%) at 1 year. Transient surgical morbidity was showen in four patients and included dysarthria, hypotonia and confusion. Conclusion : We conclude that pallidotomy is safe and effective in patients who have levodopa-reponsive parkinsonism with severe symptom fluctuation. Unilateral pallidotomy also considered helpful to ipsilateral symptom. Unilateral pallidotomy can improve all of parkinsonian's symptom and allow to reduce the levodopa medication. Most of patients show satisfactory results.

Diadochokinetic (DDK) speech task has been utilized as an evaluating tool for speakers with dysarthria for many years. This study attempted to differently diagnose multiple system atrophy (MSA) from idiopathic Parkinson's disease (PD) using patients' performance of DDK (i.e., alternate motion rate (AMR)). The subjects included 11 cases of pathologically confirmed MSA and 16 IPD patients who commonly presented with parkinsonian syndrome. The speech sample of each patient was analyzed acoustically using the MSPTM(Motor Speech Profile, a module of CSL). The results showed that the average DDK rate was significantly faster in the IPD than the MSA groups in all three syllables (i.e., /puh/, /tuh/. and /kuh/). We propose the average DDK rate variable as a core clinical trait in differentiating the two pathological conditions.
